This makes 16 KB native-library compliance a release gate for ONNX Runtime, MediaPipe, FFmpeg, Sherpa-ONNX, OpenCV/NCNN, and future native deps. +5.

Both were fixed. +- Subsequent test runs exposed several recent scaffold assertion failures. The obvious source/test-contract issues in keyframe bezier evaluation, speaker-switch initial angle selection, compound-nav test fixtures, and adjustment-layer no-layer behavior were fixed. +- The final `:app:testDebugUnitTest` run compiled and executed 389 tests with 388 passing and one remaining JVM test failure in `AutoSaveStateTest.deserialize_capsPathologicalRecoveredCollections`. + +Remaining limitation: + +- This pass did not do a full UI manual run in an emulator. It was a research/planning pass, not a runtime QA pass. +- The remaining unit-test failure should be handled in a focused follow-up because it involves JVM-unit-test behavior around Android `Uri.parse()` and autosave clip recovery. diff --git a/.claude/CLAUDE.md b/.claude/CLAUDE.md deleted file mode 100644 index ec33459c..00000000 --- a/.claude/CLAUDE.md +++ /dev/null @@ -1,544 +0,0 @@ -# NovaCut — Project Instructions & Research -

The + audio launcher MIME filter is `arrayOf("audio/*", "application/ogg")` + so files some Android pickers still label with the legacy Ogg container + MIME are discoverable. +- **C.6 — Audio mastering presets** are now wired end-to-end. New + `AudioMasteringEngine.buildEffectChain(preset)` converts a curated + recipe (Podcast Voice, Music Master, Dialogue Clean, ASMR, Social Loud) + into the ordered HighPass → ParametricEQ → De-esser → Compressor → + Limiter `AudioEffect` list. `AudioMixerDelegate.applyMasteringPreset` + replaces a track's audio chain in a single undoable pass. 6 new + conversion tests cover stage ordering, conditional skips, EQ + zero-fill, de-esser threshold scaling, limiter ceiling, and compressor + param round-trip. +- **B.5 — Mixed copy/re-encode segment stitching scaffold.** New + `SmartRenderEngine.planRuns(segments)` groups consecutive same-flag + segments into `RenderRun`s, breaking on either flag change or timeline + gap. 8 new tests lock the merge rules. The composer step that + concatenates per-run outputs waits on R6.5 so FFmpeg's concat demuxer + is available. +- **R5.4c — Strings audit on engine stubs** complete. The Round 5 claim + that engines call `Toast.makeText` was incorrect for the current + codebase (zero hits). Added `EngineStringExtractionAuditTest` so a + future commit can't introduce a hardcoded engine-side toast. + Diagnostic message fields on result records (33 across + `ProjectArchive`, `TemplateCompatibility`, + `TimelineExchangeValidator`) are tracked as a separate localization + workstream. +- **R5.5d — Local-only diagnostic export** engine layer shipped. + `DiagnosticExportEngine` writes a ZIP under `filesDir/diagnostics/` + with app/device/codec/model/logcat sections — sensitive substrings + redacted before write; project content, media URIs, captions, + autosave snapshots never included by contract. Self-prunes past 3 + ZIPs. 8 new redaction + bundle-structure tests. Settings UI wiring + (FileProvider + ACTION_SEND) is a focused ~10-line follow-up. +- **Multi-sequence export now carries NovaCut layer opacity into Media3.** `VideoEngine` builds per-input compositor layer metadata and applies it through `NovaCutVideoCompositorSettings`, so visible video/overlay tracks keep their track opacity in the real Media3 composition path. +- **Blend fallback coverage now matches the 18-mode UI.** Hue, Saturation, Color, and Luminosity no longer fall through to Normal; the single-texture fallback now gives every exposed blend mode a distinct result while the roadmap keeps the true programmable dual-texture compositor gap explicit. +- **Editor recovery, project autosave, publish metadata, template import, LUT import, and project naming paths were hardened.** The pass adds defensive caps and safer discard behavior around paths that can otherwise lose work, parse oversized data, or create brittle saved state. +- **Project home, settings, template, media picker, and snackbar surfaces received a premium polish pass.** Reused shared chips, strengthened busy/empty/disabled/accessibility states, tightened rename validation, and improved card semantics. +- **Verification** — `git diff --check` passed. Gradle tests could not run in this environment because no Java runtime or `JAVA_HOME` is installed. The Round 6 batch above added 35+ new JVM unit tests; they have not been executed in this environment and need a `gradlew testDebugUnitTest` run on a host with a JDK to verify. + +## v3.74.9 — 2026-05-14 — Caption accessibility presets + +- **Caption Style Gallery now includes accessible presets.** A dedicated section adds WCAG-AA high-contrast, large-text, and reduced-motion caption looks instead of forcing readability work through decorative templates. +- **Template application now carries real caption style intent.** Applying a template updates caption type, font, fill, background, highlight, position, outline color/width, and shadow state so the preset affects the actual caption data, not just the gallery preview. +- **Caption stroke metadata now survives recovery.** Caption autosave serializes and restores outline color and width, and preview rendering uses the stored stroke settings for more legible text over busy video. + +## v3.74.8 — 2026-05-14 — Keyboard timeline editing + +- **Timeline clips are now keyboard-focusable.** Focus traversal can land directly on visible clip nodes, with a visible focus border and the same select/delete/split affordances exposed through keyboard events. +- **Arrow keys can move focused clips without touch.** Focused clips respond to left/right arrows with 100 ms nudges, and Shift+left/right uses a 1 second nudge; trim mode maps the same keys to slip edits. +- **Selected clips gain root-level nudge shortcuts.** Shift+left/right nudges the selected clip even when focus is on the editor shell, while Ctrl+Shift+left/right nudges by one second. + +## v3.74.7 — 2026-05-14 — Generative video cloud policy + +- **Generative video is now codified as cloud-optional only.** `GenerativeVideoPolicy` records Wan 2.2, HunyuanVideo, and VideoCrafter2 as optional cloud providers rather than on-device bundled engines. +- **Cloud trust requirements are enforced in code.** Future integrations must disclose destination, estimated upload size, data retention, and collect explicit consent before a cloud render can start. +- **Policy tests prevent accidental bundling.** JVM coverage asserts that known large video-generation providers cannot be treated as bundled on-device engines and cannot run without consent. + +## v3.74.6 — 2026-05-14 — SAM 2.1 tracked-mask target + +- **Tap-to-segment now has a concrete SAM 2.1 target policy.** `TapSegmentEngine` records SAM 2.1 Hiera Tiny ONNX as the default tracked-mask target and keeps MobileSAM as the small-device fallback. +- **Premium-device gating is explicit.** The engine now models model bytes, state-cache bytes, minimum RAM, video-propagation support, and the >200 MB premium working-set threshold instead of treating SAM as an undifferentiated stub. +- **Regression tests cover the recommendation policy.** JVM tests lock in SAM 2.1 selection on premium devices and MobileSAM fallback when premium downloads are disabled or memory is insufficient. + +## v3.74.5 — 2026-05-14 — Sherpa-ONNX Moonshine v2 target + +- **Sherpa-ONNX now targets v1.13.2.** The ASR stub records the current official Android AAR release asset and the minimum Moonshine v2 support line instead of the stale 1.10-era dependency note. +- **Moonshine v2 is the English ASR target.** `SherpaAsrEngine` now codifies Moonshine v2 Tiny as the default English model target and keeps Whisper Tiny multilingual as the fallback for non-English transcription. +- **The native payload remains intentionally gated.** NovaCut does not vendor the 50+ MB AAR into the base app until the packaging path is explicit; the runtime still falls back to the built-in Whisper ONNX engine. + +## v3.74.4 — 2026-05-14 — Timeline accessibility actions + +- **Timeline clips now have richer TalkBack descriptions.** Clip semantics include the clip name, clip type, track type, duration, start time, selected state, and locked-track state instead of relying on custom-drawn visuals. +- **Screen-reader users can edit clips directly.** Each unlocked timeline clip exposes custom accessibility actions for split, delete, nudge earlier, and nudge later; the actions select the clip first and reuse the existing editor operations. +- **Split from accessibility actions is resilient.** When the playhead is not inside the focused clip, NovaCut moves it to a safe midpoint before invoking the same split path used by the toolbar. + +## v3.74.3 — 2026-05-14 — Ultra HDR source ingest + +- **Import now records source color metadata.** `MediaImportEngine` inspects imported video tracks for HDR10, HDR10+, HLG, and Dolby Vision metadata and stores the result on clips for future export decisions. +- **Ultra HDR still-image gain maps are detected on Android 14+.** Imported image sources now check `Bitmap.hasGainmap()` through a bounded decode path, so Ultra HDR gain-map sources are no longer treated as ordinary SDR media. +- **Export confidence now understands source HDR.** The export sheet summarizes imported HDR / Ultra HDR source media before render, distinguishing SDR delivery choices from missing source metadata. +- **Autosave preserves import HDR metadata.** Clip source color metadata now round-trips through project autosave so recovery and reopened projects keep their HDR confidence context. +- **Verification** — `git diff --check`, `testDebugUnitTest`, `assembleDebug`, `assembleRelease`, release APK metadata/signature checks, and an adb uninstall/install/launch smoke pass on `R5CY34G070L` all passed. + +## v3.74.2 — 2026-05-14 — HDR export capability tiering + +- **HDR profile probing now lives in `EncoderCapabilityProbe`.** NovaCut classifies HEVC, AV1, VP9, and AV1-based Dolby Vision Profile 10 encoder profiles from `MediaCodecList`, including advertised resolution / bitrate envelopes and encoder names. +- **Export confidence now distinguishes dynamic HDR paths.** The export sheet reports HDR10+ and Dolby Vision Profile 10 support separately, avoids the generic static-HDR warning when a dynamic HDR path is available, and keeps H.264 locked to SDR. +- **Device-tier hints are visible in export.** The output details panel now shows a Standard / Advanced / Premium encode tier based on actual hardware HEVC / AV1 / VP9 encoders instead of model-name guesses, with hardware-codec and HDR-profile chips. +- **Media3 is patched to 1.10.1.** This keeps the 1.10 export foundation current and picks up the AV1-based Dolby Vision handling fix from the May 12, 2026 Media3 release. +- **Verification** — `git diff --check`, `assembleDebug`, `testDebugUnitTest`, `assembleRelease`, release APK metadata/signature checks, and an adb uninstall/install/launch smoke pass on `R5CY34G070L` all passed. + +## v3.74.1 — 2026-05-14 — Multi-track export composition + +- **Multi-track visual export is wired through Media3 1.10 Composition.** `VideoEngine` now builds one `EditedMediaItemSequence` per visible video or overlay track instead of exporting only the first visual track. +- **Track audio semantics are preserved.** Embedded clip audio now follows the source track's mute, solo, visibility, and volume settings, while dedicated audio tracks remain separate audio-only sequences in the same composition. +- **Media3 sequence builders now declare explicit track types.** `VideoEngine` uses video/audio or video-only visual sequences, audio tracks use audio-only sequences, and `ProxyEngine` emits video-only proxy transcodes. +- **Docs and roadmap are synced.** B.1 is closed, B.2 remains scoped to the real dual-input blend shader path, and stale README limitations for already-shipped speed-curve duration, text stroke export, and archive import work were removed. + +## v3.74.0 — 2026-05-14 — Media3 1.10 foundation + +- **Media3 is upgraded to 1.10.0.** The dependency catalog now pulls the current stable `androidx.media3` release across ExoPlayer, Transformer, Effect, Common, UI, and Muxer. +- **Export builder usage is ready for the removed sequence constructor.** Existing `VideoEngine` and `ProxyEngine` export paths already use `EditedMediaItemSequence.Builder`, so the 1.10 upgrade does not require a production call-site migration. +- **Version and engine labels are synced.** Build metadata, the app version string, Settings engine value, README stack table, and roadmap state now reflect the Media3 1.10 foundation release. +- **Verification** — `git diff --check`, `assembleDebug`, `testDebugUnitTest`, `assembleRelease`, release APK metadata/signature checks, and an adb install/launch smoke pass on `R5CY34G070L` all passed. + +## v3.73.2 — 2026-05-13 — Project home recovery polish + +- **Project home counts now stay trustworthy while filtering.** The hero metric uses the total project library size instead of the currently filtered result count, so an empty filter no longer makes the library look empty. +- **Empty states now explain the real situation.** First-run, no search results, empty filter views, and search-plus-filter misses get distinct copy, icon treatment, and recovery behavior. +- **Filter recovery is now one clear action.** Empty filtered views offer “Show All Projects,” which clears search and filter together, plus a secondary new-project path for users who want to keep moving. +- **Filtered result headers are more specific.** Active filter views show the filter name, visible/total project counts, and current sort context instead of the generic recent-projects heading. +- **Mobile first-run layout no longer buries the empty state.** The project home hides irrelevant search, sort, filter, and duplicate hero actions until a library exists, and filter chips now stay in a compact single-line rail. +- **Verification** — `git diff --check`, `assembleDebug`, `testDebugUnitTest`, `installDebug`, and an adb launch/UI-dump smoke pass verified the first-run project home on the connected device. + +## v3.73.1 — 2026-05-13 — Settings AI model removal polish + +- **Settings AI model removal now matches the AI Tools trust flow.** Removing Whisper or segmentation from Settings opens a clear confirmation dialog with the model impact before deleting local files. +- **AI model storage copy is now cleaner and localized.** Installed/download-size labels use string resources, and removal confirmations state the exact local storage that will be freed. +- **Settings feedback is calmer for assistive tech.** AI model success/error banners now announce as polite live-region updates instead of relying only on visual change. +- **Segmentation downloads work again.** Replaced the dead MediaPipe `float32` selfie-segmenter URL with the current `float16` model URL and pinned the downloaded file with a SHA-256 check. +- **Verification** — `git diff --check`, `assembleDebug`, `testDebugUnitTest`, `installDebug`, and an adb settings smoke pass verified segmentation download, confirmation, and removal on the connected device. + +## v3.73.0 — 2026-05-13 — Premium polish pass (trust surfaces, model storage, visual system) + +- **AI model settings now feel like a managed product surface instead of a static list.** Added a Wi-Fi-only model download preference, live install/download/error state badges, local storage disclosure, and per-model download/remove controls for Whisper and segmentation models. +- **Settings overview actions now keep users in context.** The AI Models summary card jumps to the model-management section instead of exiting Settings, and model rows now read with cleaner download-size microcopy. +- **Large model downloads now respect user trust boundaries.** Whisper and segmentation downloads read the Wi-Fi-only setting, block metered-network starts, and recover to the correct installed/not-installed state after a blocked or failed request. +- **Backup imports now show persistent recovery notes.** Successful imports with missing media, warnings, or regenerated project IDs open a structured report dialog with counts, affected files, and suggested next actions; failed imports now state that the current project was left unchanged. +- **Timeline handoff exports now surface professional validation reports.** OTIO/FCPXML validation errors open a blocking report with severity, path, and suggested fix details; lossy successful exports show post-export notes instead of relying on a transient toast. +- **Visual language tightened across user-facing surfaces.** Replaced oversized pill/oval backdrops with consistent small-radius status, metric, and chip shapes while preserving true circular controls, indicators, and color swatches. +- **Test coverage / verification** — `assembleDebug`, `testDebugUnitTest`, and `git diff --check` pass on the Android Studio JBR/SDK environment. + +## v3.72.0 — 2026-05-13 — Hardening pass (Cut Assistant correctness, resource leaks, persistence guards) + +- **Cut Assistant slice-deletion bug fixed.** `applyAcceptedCuts()` was looking up `op.clipId` AFTER the first `splitClipAt()`, which keeps the LEFT half on the original id. The "middle" lookup therefore matched the wrong slice and the engine deleted content BEFORE the silence range instead of the silence itself. The new applier diffs the per-track clip-id set across both splits, identifies the freshly-minted right half, deletes the correct slice, and ripple-shifts every subsequent clip back by the deleted span so the timeline has no orphan gaps after a batch of cuts. +- **Cut Assistant proposeCutsForReview no longer trusts pre-IO state.** Tracks are re-read from `_state.value` after `withContext(Dispatchers.IO)` returns; clips that were deleted, moved, or replaced during the waveform scan are filtered out before the engine runs, and `CancellationException` is propagated so cancelling the operation actually tears down the scope. +- **Cut Assistant review panel now drops on panel dismissal.** `dismissedPanelState()` resets `cutAssistantReview = null` alongside the other auxiliary state — opening Effects / Media Picker / any other panel no longer leaks the previous ReviewSet (which can hold per-clip word transcripts). +- **TrackedObjectKeyframe rejects NaN, out-of-range, and negative-time inputs.** Adds `require()` guards for `clipTimeMs >= 0`, finite `centerX`/`centerY`, and `[0, 1]` bounds on the center — corrupt JSON or pre-v3.71 saves can no longer slip NaN coordinates into the mosaic/blur shader pipeline where they would render as giant off-screen rectangles. +- **ProjectArchive no longer swallows CancellationException.** Both `exportArchive` and `importArchiveWithReport` re-throw `CancellationException` after cleanup, so the UI's coroutine scope sees a real cancellation instead of a misleading "import failed" `ImportResult`. +- **VideoEngine.extractThumbnail closes the bitmap leak on scale failure.** `Bitmap.createScaledBitmap` can throw OOM (an `Error`, not an `Exception`) or `IllegalArgumentException` for zero-area sizes; the source `frame` is now released on every exit path, and failure paths log so flaky thumbnail extraction is visible in logcat. +- **ModelDownloadManager deletes corrupt cached models on SHA-256 mismatch.** `isValidModelFile()` now removes the bad file before returning false, so subsequent `downloadFiles()` calls don't waste a SHA-256 pass over the same bad bytes on every launch. +- **keystore.properties added to `.gitignore`.** The file containing release-signing credentials was untracked but unprotected — one `git add -A` away from public exposure. +- **Test coverage** — Added `TrackedObjectKeyframeTest` (13 cases covering NaN/range/boundary) and `CutAssistantEngineTest` (9 cases covering projection, trim clipping, merge tolerance, accept/reject round-trip, and apply-order ordering). + +## Previous Unreleased — Export confidence and Cut Assistant polish + +- Added Color / HDR confidence chips to the export sheet, including SDR delivery status, HDR preservation intent, HDR10+ dynamic metadata support, and render-time source caveats. +- Added export mismatch warnings for H.264 HDR requests, missing device HDR encode support, and advertised HDR resolution/bitrate limits. +- Added a Preserve HDR Metadata control to Delivery Options so HDR intent is visible in the main export workflow instead of only the feature hub. +- Added a user-facing Cut Assistant workflow in the AI Hub and clip AI toolbar. +- Added a review sheet for silence/filler-word proposals with selected-by-default candidates, per-row toggles, accept/reject all, reclaimed-duration summary, and an empty state. +- Applying reviewed proposals still uses the existing `applyAcceptedCuts()` path, so the batch lands as one undoable timeline edit. +- Added a Tracked Mosaic effect that binds persisted TrackedObject keyframes to a Media3 shader mask, with preview/export wiring, target-ID autosave, interpolation tests, and an Effects panel action for tracked masks on the selected clip. +- Added template compatibility metadata to saved/exported templates, including schema version, minimum app version, required feature list, and media/text slot counts. +- Added compatibility validation to template imports so future-schema, newer-app, or unknown required-feature templates are rejected before they are saved locally, with clearer user-facing failure copy. +- Saved template cards now surface slot counts so reusable setups feel more inspectable before opening. +- Surfaced the existing stream-copy fast trim path in the export sheet with a user-visible "Fast Trim When Possible" control, and refreshed stale copy around the MediaMuxer fallback behavior. +- Clarified the roadmap split between shipped whole-timeline stream-copy and the still-open mixed segment smart-render bypass. +- Corrected speed-ramp clip duration by integrating eased `speedCurve(t)` directly, keeping timeline length, thumbnail scrubbing, and export timing aligned on variable-speed clips. + +## v3.71.0 — 2026-04-25 — Cut Assistant + TrackedObject scaffolding + +Second slice of the ROADMAP "Highest-leverage next tickets" — the engine and +state-layer prerequisites for the Creator-speed and Object-aware releases. + +### CutAssistantEngine (C.2 / R4.5) +New [CutAssistantEngine.kt](app/src/main/java/com/novacut/editor/engine/CutAssistantEngine.kt) +is a pure planner that combines `SilenceDetectionEngine.detectSilences()` and +`detectFillerWords()` into a single sorted, de-duplicated `ReviewSet`: + +- Walks every video/audio clip on the timeline and projects clip-source ms + into timeline ms, accounting for trim handles + speed + speedCurve via + `Clip.durationMs` scaling. Proposals straddling a trim handle contribute + only the visible portion. +- Merges abutting same-clip proposals within a 250 ms tolerance so a + "um... uh..." run shows up as one review row instead of three. +- Drops contributions shorter than 80 ms after trim clipping (visual jolt + outweighs time saved). +- `planAcceptedOperations()` emits `CutOperation.RippleDelete` entries + ordered latest-first so the applier can split + delete each one without + invalidating the indices of the remaining operations. + +### EditorViewModel orchestration +`proposeCutsForReview()` extracts denser per-clip waveforms (~20 samples/sec, +bounded 200..10 000) via `audioEngine.extractWaveform()`, looks up cached +transcript words via `perClipWordsFor()`, runs the engine, stashes the +`ReviewSet` in `state.cutAssistantReview`. Per-proposal `toggleCutProposal`, +`acceptAllCutProposals`, `rejectAllCutProposals` are pure state-updaters. +`applyAcceptedCuts()` wraps the whole batch in a single +`saveUndoState("Apply Cut Assistant")`, processes ops latest-first, splits at +start + end of each accepted range and deletes the middle slice via existing +primitives. `dismissCutAssistantReview()` closes the review without +applying. + +### TrackedObject model (R4.3 — object-aware editing scaffold) +[TrackedObject.kt](app/src/main/java/com/novacut/editor/model/TrackedObject.kt) +defines the engine-agnostic data classes that future tracked operations +(blur, mosaic, sticker attach, color grade, audio focus) will bind to: + +- `TrackedObject` (id, label, sourceClipId, source, category, isEnabled, + keyframes). +- `TrackedObjectKeyframe` (clipTimeMs, normalised centerX/centerY/width/height + in [0, 1] — survives a 1080p → 4K source swap without drift; confidence; + optional maskPolygon for SAM-class trackers). +- `TrackedObjectSource` enum (MANUAL / MEDIAPIPE / MOBILE_SAM / SAM2 / + YOLO_TRACK) and `TrackedObjectCategory` enum (PERSON, FACE, VEHICLE, + LICENSE_PLATE, ANIMAL, TEXT, PRODUCT). +- Persisted via new `AutoSaveState.trackedObjects` field; deserialiser + coerces coords into the valid range BEFORE constructing the keyframe so a + corrupt save can't trip `require()` and silently drop the rest of the + object's track.

Covers: empty trim ranges, missing source URIs, EDL multi-track +truncation, adjustment-track drop, blend-mode loss, masks, color grade, +reverse playback, speed ramps, compound flatten, EDL transition downgrade. + +### ProjectArchive.importArchive() — full diagnostic pass (B.7) +[ProjectArchive.kt](app/src/main/java/com/novacut/editor/engine/ProjectArchive.kt) +gains `importArchiveWithReport()` returning an `ImportResult(state, report, +errorMessage)`. The report carries schema version, schema-too-new gate, +project-ID collision detection (with `IdCollisionPolicy.REGENERATE` / +`KEEP`), per-archive media-resolution counts, and unresolved-media URI list. +Legacy `importArchive()` stays as a thin wrapper for unchanged callers. +`EditorViewModel.importProjectBackup()` now reads the existing project IDs +from `ProjectDao`, calls the rich variant, and surfaces missing-media and +collision warnings in the toast.

SpannableString could never do this — +the draw model only carries one color per pixel. `VideoEngine` branches on +`overlay.strokeWidth > 0f`: zero-stroke overlays still take the cheap +`ExportTextOverlay` path, so the common case pays no cost. Bitmaps are cached +per text change and released when Media3 releases the overlay. + +### B.5 — Multi-clip same-source stream-copy +[StreamCopyMuxer.concat](app/src/main/java/com/novacut/editor/engine/StreamCopyMuxer.kt) +now muxes a list of non-overlapping source windows into a single output file +— the multi-clip-same-source case where a creator has sliced one recording +into keepers. Each track walks the ranges independently with its own output +cursor; sample packets are never decoded. +[StreamCopyExportEngine.analyze](app/src/main/java/com/novacut/editor/engine/StreamCopyExportEngine.kt) +now accepts any number of clips on a single visible video track as long as +they all share the same source URI and every clip passes the full +`firstDisqualifier` list.

The second pass (this section) +turned every dead UI toggle into a live consumer, wired the stream-copy path +through the Android MediaMuxer (no FFmpeg dependency required), added real +HDR preservation via `Composition.HDR_MODE_KEEP_HDR`, fixed a ripple-delete +bug in text-based editing, and persisted transcripts so text-based editing +survives app restart. + +### Wide-net additions + +- **Color-blind preview GL pass** — `ColorBlindGlEffect` builds a fragment + shader from the `ColorBlindPreviewEngine` matrix and appends it to every + clip's preview effect chain. Toggling the mode in the v3.69 panel now + produces a visible preview change within one frame. Export never picks up + the effect. +- **Stream-copy via `MediaMuxer`** — new `StreamCopyMuxer` uses + `MediaExtractor` + `MediaMuxer` to remux the source packets directly into + the destination, no transcode. `ExportDelegate.trySteamCopy()` guards with + the full eligibility checklist; any failure transparently falls back to the + Transformer path so users can't get stuck. 50× faster on eligible trims. +- **HDR preservation on export** — `VideoEngine.buildComposition` respects + `ExportConfig.hdr10PlusMetadata` by setting `Composition.HDR_MODE_KEEP_HDR` + when the codec can carry HDR (HEVC/AV1/VP9). H.264 forces SDR since it has + no HDR profile. The v3.69 panel switch is now gated on codec choice and + shows "Switch to HEVC/AV1/VP9" when locked. +- **Keyframe remap on text-based split** — `V369Delegate.buildSegment` + filters the source clip's keyframes to the segment's source-time window and + remaps each kept `timeOffsetMs` via `Clip.sourceTimeToTimelineOffsetMs`. + Speed-curves are restricted via `SpeedCurve.restrictTo` so preview and + export time-stretching stay consistent with each segment's trim window. +- **Transcript persistence** — `AutoSaveState.transcript` is now part of + the auto-save JSON; `V369Delegate.setTranscript` calls `saveProject`; + `EditorViewModel` restores it into `v369.transcript` on recovery.

Follows the Tier-A stub convention: real implementation where the Android surface allows, structured hook for the rest. No new third-party dependencies. + +### New engines + +- **TextBasedEditEngine** — Descript/CapCut Script-Editor-style edit flow. Word-level `WordTimestamp` selections map to source-time cut ranges on the selected clip; contiguous selections coalesce (120 ms merge window). `fillerWordIndices()` covers the mainstream English filler set. +- **AutoChapterEngine** — TextTiling-lite over Whisper words: 24-word sliding windows, cosine similarity of bag-of-words between adjacent windows, local minima mark chapter boundaries. `formatYouTubeClipboard()` renders an `HH:MM:SS Title` block ready for a YouTube description. +- **TalkingHeadFramingEngine** — Samsung Auto-Framing / Apple Center Stage equivalent. Skin-tone centroid as a face-proxy per sampled frame, one-euro filter smoothing on the trajectory, output as `POSITION_X/POSITION_Y` keyframes so the existing keyframe-aware export path picks them up. +- **KaraokeCaptionEngine** — Submagic/Captions.ai-style word-pop captions, 8 preset styles (MrBeast, Subway, Hormozi, TikTok White, Pop Scale, Typewriter, Neon, Minimal). Emits standard `TextOverlay` instances with animation + stroke that the current export pipeline already renders. +- **StreamCopyExportEngine** — LosslessCut eligibility detector. When the timeline is a single unmodified clip with only head/tail cuts, signals the export pipeline to skip transcode entirely. Stream-copy mux itself is invoked through `FFmpegEngine.streamCopyTrim()` (added as a stub; lights up once A.9 ships). +- **ContentIdEngine** — Copyright fingerprint / AcoustID pre-check. Energy-envelope hash per 50 ms window over 16-bit PCM; hash-only result when no API key is configured, AcoustID lookup when one is. Fingerprint-similarity helper for local dedup. +- **DirectPublishEngine** — Facade for YouTube / TikTok / Instagram Reels / Threads / X / LinkedIn. Resolves to a platform-branded share intent when the target app is installed; documents the OAuth-upload hook for partner-program integrations. +- **FlashSafetyEngine** — WCAG/Harding-lite photosensitive-epilepsy scan. Samples luminance + red-channel at 10 Hz, flags 1 s windows with >3 opposite-direction transitions above the Δ threshold. Separate general-flash vs. red-flash categories per W3C guidance. +- **ColorBlindPreviewEngine** — Brettel/Viénot CVD simulation (Deuteranopia / Protanopia / Tritanopia / Achromatopsia). Ships both a 3×3 transform matrix and an inlined GLES 3.0 fragment shader so the existing `ShaderEffect` framework can apply it as a preview-only pass. +- **AiThumbnailEngine** — YouTube-cover-style frame ranker. Score = 0.35·Laplacian-variance sharpness + 0.25·rule-of-thirds alignment of the salient-edge centroid + 0.40·skin-tone coverage. Top-N candidates returned with bitmaps; `saveThumbnail()` writes a JPEG. +- **AudioDescriptionEngine** — SDH tags (`[music]`, `[door slams]`, …) + audio-description-track generator.

Accessed from the editor top-bar overflow menu → "v3.69 Features" (`Icons.Default.AutoAwesome`, Mauve tint). +- **V369Delegate** — follows the existing delegate pattern: owns coroutine jobs, writes to the shared `EditorState` via the CAS-loop `update` extension, pulls through `saveUndoState`/`saveProject`/`rebuildPlayerTimeline`. +- **EditorState.v369** nested `V369State` block: transcript, selected-word indices, chapter candidates, flash warnings, thumbnail candidates, color-blind mode, karaoke style, stream-copy eligibility, content-ID result, four in-flight flags. +- **PanelId extension** — added `V369_FEATURES` hub plus drill-down IDs for `TEXT_BASED_EDIT`, `AUTO_CHAPTER`, `TALKING_HEAD`, `KARAOKE_CAPTIONS`, `CONTENT_ID`, `DIRECT_PUBLISH`, `FLASH_SAFETY`, `COLOR_BLIND_PREVIEW`, `AI_THUMBNAIL`, `AUDIO_DESCRIPTION`. + +### Model additions + +- `model/Transcript.kt` — shared `WordTimestamp` and `Transcript` primitives so the ASR, text-based edit, auto-chapter, karaoke, and audio-description pipelines all speak the same shape instead of each depending on nested types under `WhisperEngine` / `SherpaAsrEngine`. + +## v3.68.0 — Performance & Responsiveness Pass + +Broad optimization sweep across recomposition hotspots, per-tick I/O, and hot-path allocation. No new features. No DB schema changes. No new dependencies. + +### Compose recomposition fixes + +- **Per-clip `Brush.verticalGradient` overlay hoisted to `remember`** in `Timeline.kt`. The gradient applied on top of every clip body was allocated fresh per clip per frame. A 10-clip project recomposing at 30 Hz during playback was churning 300 `Brush` + `List` allocations/sec for a gradient whose contents never change. +- **Render-phase snap-target list memoized** via `remember(track.clips, selectedClipId, playheadMs, beatMarkers, markers, snapToBeat, snapToMarker)`. The `flatMap { filter { } flatMap { } }.distinct().plus(...).let { ... }.let { ... }` chain was running on every playhead tick, allocating 5–7 `List` instances per tick. +- **`volumeKeyframesSorted(clip)`** memoized per-clip on `clip.keyframes`. Sort is O(n log n); previously ran on every audio clip every recomposition. +- **`previewTrackClips` / `previewClipAtPlayhead` derives decoupled from `playheadMs`** in `EditorScreen.kt`. The sort that built `previewTrackClips` was re-keyed on `playheadMs` via the downstream derive chain, so a static clip list was being re-sorted 30 times/sec during playback. The sort now only re-runs when the track structure actually changes; the per-tick scan stays cheap because the sorted list is cached. + +### Per-tick I/O reduction + +Eight slider/gesture paths no longer call `saveProject()` on every `onValueChange` tick. All have matching `begin*/end*` hooks so the full-project JSON serialize + disk write runs once per gesture instead of 60 times per second: + +- `EffectsDelegate.updateEffect` → `endEffectAdjust()` +- `AudioMixerDelegate.setTrackVolume` → `endVolumeAdjust()` +- `AudioMixerDelegate.setTrackPan` → `endPanAdjust()` +- `setClipVolume` → `endVolumeChange()` +- `setClipTransform` → `endTransformChange()` +- `setClipOpacity` → `endOpacityChange()` (new hook) +- `setClipFadeIn` / `setClipFadeOut` → `endFadeAdjust()` +- `beginSlideEdit`/`beginSlipEdit` now call `setScrubbingMode(true)` too (previously only `beginTrim` did) + +The preview-pan pinch gesture in `PreviewPanel.kt` was rewritten from `detectTransformGestures` to `awaitEachGesture` so it actually has an end hook — the old implementation had no way to signal "gesture finished", which is why `setClipTransform` had been calling `saveProject()` on every frame in the first place. `TransformOverlay.onDragEnd` and `onDragCancel` now call `onTransformEnded()`. AI tool callers that relied on `setClipTransform` auto-saving (smart crop, smart reframe) explicitly `saveProject()` after their one-shot invocation. + +### Playback loop + +- **Playhead sync's per-5-frame state broadcast now gated on drift ≥200ms** in `EditorViewModel.kt`. During playback, every 5th frame unconditionally emitted a new `EditorState` with the updated `playheadMs` — a 40-field `state.copy()` that invalidated every Compose subscriber of the state flow ~6 times/sec. The dedicated `_playheadMs` flow already served live-playhead consumers, so the full-state broadcast is now only needed to keep `state.playheadMs` fresh enough for user-triggered reads like `splitClipAtPlayhead()` and autosave — a 200ms drift threshold cuts broadcasts from ~6/sec to ~5/sec while keeping staleness bounded. + +### Usability + +- **Clip-label picker close button grown from 24dp to 44dp** to meet the Material 3 minimum touch-target guideline. The icon inside went 16dp → 20dp. The previous tap target was below accessibility minimums and frequently misfired on small phones. + +## v3.67.0 — Snackbar Height, Drag Responsiveness, Suggestion Cleanup + +Follow-up fixes based on v3.66 user testing. + +### Snackbar covering the screen (also broke video playback) + +- **`PremiumSnackbar` accent stripe used `fillMaxHeight()` inside a height-unconstrained Row.** Compose resolves `fillMaxHeight` against the nearest height-constrained ancestor — which in this case was the screen-root `Box`. So a "Clips split" toast was not just visually oversized, its opaque-ish Surface absorbed touch input across the whole area, which is why the play button appeared unresponsive immediately after a split. Two-line fix: added `.wrapContentHeight()` on the Surface and `.height(IntrinsicSize.Min)` on the Row, so `fillMaxHeight` now resolves against the Row's wrap-content height (≈52dp) instead of the screen. + +### Timeline drag responsiveness + +- **`trimClip`, `slideClip`, and `slipClip` no longer call `rebuildPlayerTimeline()` on every tick.** All three fire at touch-event rate (60–120 Hz) during a drag; tearing down and rebuilding ExoPlayer's `MediaItem` + `ClippingConfiguration` set on every tick was the primary cause of the "clunky" feel. The rebuild is deferred to `endTrim` / `endSlideEdit` / `endSlipEdit`, which run exactly once per gesture. `beginSlideEdit` and `beginSlipEdit` now also call `videoEngine.setScrubbingMode(true)` (previously only `beginTrim` did), so ExoPlayer skips intermediate seek/decode work across all three edit modes. + +### Suggestion banner cleanup + +- **Removed the unsolicited "This clip could use color correction" suggestion banner.** Fired every time a long visual clip was selected that happened to have no effects — noise, not signal. Users can still trigger auto-color from the AI tools panel. The other two suggestions (add transitions, denoise on low-variance audio) are preserved because they gate on more specific conditions. + +## v3.66.0 — Timeline & Editing Overhaul + +Focused rework of the timeline gesture model and viewport framing. Addresses three long-standing usability issues: trim handles not responding to drags, cut/split being hard to find, and long clips appearing to show only a tiny editable window. No DB schema changes, no new dependencies. + +### Timeline gesture unification + +- **Unified clip-body pointer input replaces three competing gesture detectors.** Previously each clip had a parent `detectDragGestures` for slide/slip and two nested `detectHorizontalDragGestures` blocks for the left and right trim handles. All three waited for drag-slop on the same down event, and the parent body detector routinely consumed edge drags before the handle detectors could react — which is why pulling on the edge of a clip to trim often did nothing. A single `detectDragGestures` on the clip body now measures the touch X position at drag start and routes the gesture to one of four zones: `TRIM_LEFT` (within the 28dp edge zone), `TRIM_RIGHT` (within the 28dp trailing zone), `SLIP` (middle zone, trim-tool active), or `SLIDE` (middle zone, arrange-tool active). The nested handle pointer inputs are removed. Drag events are explicitly consumed so the ancestor pinch-zoom detector doesn't double-handle them. Trim and slide/slip now work reliably regardless of the active tool mode. +- **Selected clip shows thicker edge handles with grip lines.** When a clip is selected, the trim-handle visual width grows from 14dp to 18dp and three 1.2dp vertical grip lines appear — an unambiguous affordance cue that the edge is draggable. Matches the CapCut / KineMaster edit UX where the selected clip's edges are visibly distinct from inactive clips. + +### Full-duration viewport framing + +- **Minimum zoom lowered from 0.1 → 0.01.** The old 0.1 floor meant the fit-to-window calculation couldn't actually fit videos longer than ~60 seconds on a phone screen — the computed fit-zoom was clamped *above* the ratio that would have worked. The new 0.01 floor lets a 10-minute project fit the editable area cleanly. The max 10.0 remains unchanged. +- **Auto-fit on first layout.** A new `fitTimelineToWindow()` method in `EditorViewModel` computes the fit-zoom from the current viewport width and project duration, and resets scroll to zero. It fires automatically: (1) the first time `setTimelineWidth` transitions from 0 → non-zero with content already present, (2) after autosave/Room restore populates tracks, and (3) after the first clip is added to an empty project. A `pendingInitialFit` flag ensures this runs once per session — the user's subsequent zoom preferences are not overridden. Matches the CapCut / VN behaviour where importing a clip immediately frames the whole asset. +- **Viewport overview strip below the tracks.** A new `TimelineOverviewBar` composable renders a full-project-duration strip with one rectangle per clip (coloured per track type), a highlighted "viewport" window showing what's currently visible, and a playhead tick. Tap or drag on the strip to scroll — centering the viewport on the tapped position. Primary purpose is *discoverability*: users can see at a glance that there is more content off-screen and can jump directly to any timestamp without having to pinch-zoom out first. Only shown when `totalDurationMs > 0`. + +### Cut / delete accessibility + +- **Prominent "Cut at playhead" and "Delete selected" buttons added to the timeline toolbar row.** Previously split was only reachable through a two-level tool sub-menu or a radial long-press menu; both paths were difficult to find. The new split button sits between the zoom controls and the marker-add button, uses `Icons.AutoMirrored.Filled.CallSplit`, is styled with the Peach accent + highlight border so it reads as a primary action, and calls `viewModel::splitClipAtPlayhead` directly. The delete button auto-disables when no clip is selected. Both are always visible, regardless of the current tool mode. + +### Internals + +- `TimelineToolbarButton` gained `highlight: Boolean` and `enabled: Boolean` parameters so the split button can render as a prominent accented action and the delete button can render as greyed-out when disabled. Default values preserve existing call sites unchanged. +- `ClipGestureZone` enum (`TRIM_LEFT`, `TRIM_RIGHT`, `SLIDE`, `SLIP`, `NONE`) defined at file scope in `Timeline.kt` to make the unified gesture routing explicit. +- Zoom constants `MIN_TIMELINE_ZOOM = 0.01f` and `MAX_TIMELINE_ZOOM = 10f` lifted to file-scope constants in both `Timeline.kt` and `EditorViewModel.kt` to keep the zoom clamps consistent across pinch, toolbar buttons, and the fit-to-window calc. + +## v3.65.0 — Deep Audit Phase 27: Error-Path Allocation & OOM Cleanup + +Targeted correctness fixes from continued engineering audit. No behaviour change on valid inputs, no new dependencies. + +### Bug fixes + +- **`AudioEngine.extractWaveform` — exception path allocated unbounded `FloatArray(sampleCount)`** — Every other return path in `extractWaveform` allocates `FloatArray(boundedSampleCount)`, where `boundedSampleCount = sampleCount.coerceAtMost(10_000)` caps the result at ~40 KB. The outer `catch (e: Exception)` block silently violated this contract by allocating `FloatArray(sampleCount)`. Callers that pass a large `sampleCount` (e.g. `48_000` for a high-resolution scrub waveform) would receive a 192 KB array on decoder failure instead of the expected 40 KB, and — because callers may cache the result under the `"uri|sampleCount"` key — repeated failures compound into a persistent oversized cache entry. Fixed: use `boundedSampleCount` on the exception path to match the other four return paths in the function. Completes the v3.59.0 fix which patched the `audioTrackIndex < 0` path but left the outer catch unfixed. + +- **`ContactSheetExporter.export` — PNG-encoder OutOfMemoryError bypassed partial-file cleanup** — `sheet.compress(…)` allocates native PNG-encoder buffers (~bitmap-sized) and can raise `OutOfMemoryError` on very large contact-sheet grids. The outer `catch (e: Exception)` block did not catch `OutOfMemoryError` (a `Throwable` subclass, not `Exception`), so the `outputFile.delete()` cleanup was skipped. The `finally` block still recycled the source bitmap (no native leak), but a half-written or 0-byte PNG was left on disk — subsequent opens would silently serve that file as though the export had succeeded, and the user would see a truncated contact sheet without any error toast. Fixed: widen the catch to `Throwable`, but rethrow `CancellationException` first so coroutine cancellation still propagates to the caller instead of being swallowed as a generic "render failed" result. + +### Notes +- No DB schema changes. No new dependencies. No UI changes. + +## v3.64.0 — Deep Audit Phase 26: Defensive Hardening + +Defensive improvements from final end-to-end engineering audit sweep. No behaviour change on valid inputs, no new dependencies. + +### Improvements + +- **`BeatDetectionEngine.fft` — undocumented power-of-2 contract now enforced** — The Radix-2 Cooley-Tukey FFT implementation requires its input arrays to have power-of-2 length; this was documented in a comment but not enforced in code. A non-power-of-2 input produces an incorrect bit-reversal permutation and a silently corrupted frequency spectrum, yielding wrong beat timings with no error signal. Added `require(n > 0 && (n and (n - 1)) == 0)` at the top of `fft()` so any future caller passing a wrong-sized array fails fast with a clear diagnostic instead of silently producing corrupt beat maps. + +- **`SettingsRepository.updateDefaultCodec` — silent rejection now logged** — When an unrecognised codec string is passed to `updateDefaultCodec`, the method silently returns without writing to DataStore. This is the correct defensive behaviour, but the absence of any log message makes it invisible during debugging or when tracing unexpected UI state (e.g. the codec dropdown appearing to reset). Added `Log.w("SettingsRepository", "Ignoring unknown codec value: $value")` before the early return so that corrupt or migrated settings strings surface in logcat without changing the validation logic. + +## v3.63.0 — Deep Audit Phase 25: Segmentation and Stabilization Reliability + +Targeted correctness and defensive fixes from continued end-to-end engineering audit of AI processing and segmentation layers. No behaviour change on valid inputs, no new dependencies. + +### Bug fixes + +- **`SegmentationEngine` — `avgConfidence` divided by full pixel count instead of actual iteration count** — The confidence accumulation loop was bounded by `minOf(floatBuffer.remaining(), w * h)` to avoid over-reading a short buffer, but the average was computed as `totalConfidence / (w * h)` using the full frame size. When MediaPipe returns a shorter buffer than `w * h` pixels, the average is artificially deflated, potentially causing callers to reject a valid high-confidence segmentation mask as too uncertain. Edge case: if `w * h == 0` (e.g. the model output has degenerate dimensions), the division produces `NaN`, which propagates to the `SegmentationResult.confidence` field. Fixed: track the actual loop iteration count as `pixelCount = minOf(floatBuffer.remaining(), w * h)` and divide by `pixelCount`; guard against the zero case with an explicit `if (pixelCount > 0) … else 0f`. + +- **`AiToolsDelegate.applyStabilization` — partial output file not cleaned up on error or cancellation** — After `stabilizationEngine.analyzeMotion()` succeeds, a `File` object for the output MP4 (`cacheDir/stabilized_.mp4`) is created and passed to `stabilize()`. If `stabilize()` returns `null` (error path) the output file was left on disk uncleaned; if the coroutine is cancelled during `stabilize()` (via `cancelAiTool()`) the `CancellationException` propagated without deleting any partial write. Repeated cancellations accumulate orphaned files, each potentially hundreds of MB when the real OpenCV integration ships. Fixed: wrapped the `stabilize()` call in `try/catch(Exception)` — deletes the output file before re-throwing so CancellationException also triggers cleanup. Added explicit `outputFile.delete()` in the null-result branch. + +## v3.62.0 — Deep Audit Phase 24: Rendering, Subtitle, and Proxy Reliability + +Targeted correctness fixes from continued end-to-end engineering audit across Lottie rendering, subtitle export, and proxy generation. No behaviour change on valid inputs, no new dependencies. + +### Bug fixes + +- **`LottieTemplateEngine` — NaN progress on zero-duration composition** — `(frameTimeMs.toFloat() / composition.duration).coerceIn(0f, 1f)` produces `NaN` when both operands are zero (frame 0 of a malformed/empty animation where `duration = 0`). IEEE 754: `0f / 0f = NaN`; `NaN.coerceIn(…)` returns `NaN` because all NaN comparisons return false. Passing `NaN` to `drawable.progress` renders the animation at an undefined frame position, corrupting any title overlay in the exported video. Fixed: guard the denominator with `takeIf { it > 0f } ?: 1f`. + +- **`ContactSheetExporter` — bitmap leaked when Paint or Canvas construction throws OOM** — `Canvas(sheet)` and three `Paint(…)` objects were created between the OOM-guarded `Bitmap.createBitmap` block and the `try { } finally { sheet.recycle() }` block. Any `OutOfMemoryError` raised during `Paint.ANTI_ALIAS_FLAG` native allocation or `Typeface.create()` would propagate past both the catch and the finally, leaving the large sheet bitmap unreleased. On devices that are already memory-constrained (the reason the batch-export flow exports in one-at-a-time fashion), repeated leaks accumulate and cause OOM crashes. Fixed: moved `Canvas` and all `Paint` initialisations inside the `try` block so the `finally { sheet.recycle() }` guards the entire render path. + +- **`SubtitleExporter` — VTT word-level cue timestamps not validated against caption bounds** — Word-level timestamps in `Caption.words` are passed directly into `<${formatVttTime(word.startTimeMs)}>` cues without checking that they fall within the caption's `startTimeMs..endTimeMs` range. The WebVTT spec requires word timestamps to lie within the parent cue's range; parsers in browsers and media players silently discard the entire cue when this is violated, causing the affected subtitle line to disappear entirely. Fixed: filter `caption.words` to only those whose `startTimeMs` falls in `caption.startTimeMs..caption.endTimeMs` before emitting cue tags. Falls back to plain caption text when no valid word cues remain. + +- **`ProxyWorkflowEngine` — cancellation not checked between proxy generation jobs** — The `for ((clipId, entry) in needsProxy)` loop did not call `ensureActive()` before starting each clip's `proxyEngine.generateProxy()` call. WorkManager cancels the owning coroutine when the device goes to sleep, battery-saver activates, or the user cancels the background task; without a cooperative check the loop continues until the process is forcibly killed, burning CPU/battery and leaving partial proxy files. Fixed: added `ensureActive()` at the top of each iteration so cancellation is observed promptly before each potentially multi-minute encode begins. + +## v3.61.0 — Deep Audit Phase 23: Concurrency, Export, and Storage Reliability + +Targeted correctness and reliability fixes from continued end-to-end engineering audit of export, persistence, and storage layers. No behaviour change on valid inputs, no new dependencies. + +### Bug fixes + +- **`ProjectListViewModel` — template share fails on devices without external storage** — `getExternalFilesDir(null)` returns `null` when external storage is unavailable (formatted as internal, removed, or permission-restricted). `File(null, "archives/templates")` creates a relative path, causing `FileProvider.getUriForFile()` to throw `IllegalArgumentException("Failed to find configured root")`, silently reporting "Template export failed". Fixed: fall back to `filesDir` when external storage is unavailable. Also added a `` entry to `file_paths.xml` so FileProvider can serve files from the internal fallback path. + +- **`ProjectAutoSave` — `copyAutoSave()` checked file existence outside the mutex** — `fromFile.exists()` was evaluated before `saveMutex.withLock {}`, leaving a race window where a concurrent `clearRecoveryData()` could delete the file between the check and the read, producing a `FileNotFoundException` rather than a clean `false` return. Moved the `exists()` check inside the lock so the check, read, mutate, and write happen atomically with respect to all other save/load operations. + +- **`VideoEngine` — `cancelExport()` read `activeExportOutputFile` without synchronization** — `export()` assigns `activeExportOutputFile = outputFile` inside a `synchronized(this)` block, but `cancelExport()` read and nulled it without any synchronization. Under the JVM memory model, a non-volatile field written after a volatile store has no happens-before guarantee for unsynchronized readers. In the narrow window between state being set to EXPORTING and `activeExportOutputFile` being assigned, a concurrent cancel call would read `null` and fail to delete the partial output file. Fixed: wrapped `cancelExport()` body in `synchronized(this)` to match the lock used in `export()`, keeping progress update outside the lock (non-critical, no synchronization requirement). + +- **`ExportDelegate` — `cancelExport()` missed state update for GIF and early-cancel paths** — The UI state update to `CANCELLED` was guarded by `if (currentState == ExportState.EXPORTING)`. For GIF exports (running on `nonVideoExportJob`, not through VideoEngine's state machine) or when cancel is tapped before state propagates to EXPORTING, the guard evaluated to false and the stateFlow was never updated. The cancel button would appear to do nothing. Fixed: always push `CANCELLED` state; the cancel button is only reachable while an export is active so CANCELLED is always the correct terminal state. + +- **`ExportDelegate` — batch export advanced to next item without waiting for current export** — `videoEngine.resetExportState()` resets the VideoEngine's internal state to IDLE but does not update the ExportDelegate's `stateFlow.exportState`. The wait loop `stateFlow.map { it.exportState }.first { it != IDLE && it != EXPORTING }` therefore immediately returned the previous item's COMPLETE/ERROR state, marking the new item as COMPLETED before its export had started. Two items would export concurrently, and their statuses would be misattributed. Fixed: reset `exportState` and `exportProgress` in the `stateFlow.update` call alongside `exportConfig` so the wait loop correctly waits for the new export to reach a terminal state. + +- **`ExportDelegate` — batch progress collector not joined before next item** — `progressJob.cancel()` signals cancellation but does not wait for the collector coroutine to finish. The collector could still be executing a `stateFlow.update` on the just-finished item while the next item's coroutine started its own `stateFlow.update`, producing a concurrent write race on the batch queue list. Fixed: added `progressJob.join()` after `progressJob.cancel()` to ensure the old collector fully stops before the next iteration begins. + +### Notes +- No DB schema changes. No new dependencies. `file_paths.xml` adds `` as a new FileProvider root for internal-storage template sharing. + +## v3.60.0 — Deep Audit Phase 22: Frame Capture & Timeline Reliability + +Targeted correctness fixes found during continued end-to-end engineering audit of delegate and engine files. No behaviour change on valid inputs, no new dependencies. + +### Bug fixes + +- **`FrameCapture` — bitmap leak on `createScaledBitmap` OOM** — `Bitmap.createScaledBitmap()` throws `OutOfMemoryError`, which is a `Throwable` (not an `Exception`). The outer `catch (e: Exception)` block did not catch it, so the source bitmap was never recycled on OOM, causing a native memory leak. Fixed: wrap the scale call in a dedicated `catch (t: Throwable)` that recycles the bitmap and returns `null`, consistent with the function's existing null-on-failure contract. + +- **`ClipEditingDelegate` — split clip loses linked audio ID when audio track is locked** — When a video clip on an unlocked track was split, the second-half copy had its `linkedClipId` resolved through `newIdsByOldId[linkedId]`. If the linked audio clip was on a locked track (and therefore not included in the split), `newIdsByOldId[linkedId]` returned `null`, silently setting `linkedClipId = null` on the new clip. Audio and video then played out of sync with no user-visible error. Fixed: fall back to `?: linkedId` to preserve the original link when the paired clip was not part of the split operation. + +### Notes +- No DB schema changes. No new dependencies. No UI changes. + +## v3.59.0 — Deep Audit Phase 21: Engine Reliability Fixes + +Targeted correctness and reliability fixes found during an end-to-end engineering audit of all engine and delegate files. No behaviour change on valid inputs, no new dependencies. + +### Bug fixes + +- **`AudioEngine` — `FloatArray(sampleCount)` OOM bypass** — When no audio track was found, the early-return path allocated `FloatArray(sampleCount)` instead of `FloatArray(boundedSampleCount)`. Callers that pass a large `sampleCount` (e.g. 48 000) would receive a much larger array than the 10 000-element cap applied everywhere else in the function, silently defeating the OOM guard. Fixed: use `boundedSampleCount` on the early-return path, consistent with the rest of the function. + +- **`ProxyEngine` — stale zero-byte proxy served as valid** — The cached-file existence check used `outFile.exists()`, which returned `true` for a zero-byte stub left by a prior failed Transformer run. The code would then cache and return this broken URI without re-rendering. Fixed: check `outFile.isFile && outFile.length() > 0L`, mirroring the identical guard already present in the `onCompleted` callback. + +- **`MultiCamEngine` — integer divide-by-zero on `targetSampleRate = 0`** — `max(1, sourceSampleRate / targetSampleRate)` computes the integer division before `max` runs; a caller passing `targetSampleRate = 0` would throw `ArithmeticException`. Fixed: coerce `targetSampleRate` to at least 1 before the division. + +- **`MultiCamEngine` — `Float.POSITIVE_INFINITY` poison from `channels = 0`** — `format.getInteger(KEY_CHANNEL_COUNT)` can return 0 from a malformed or synthetic `MediaFormat`. `mono /= channels` then produces `Float.POSITIVE_INFINITY`, which propagates through the entire decoded sample list and corrupts multi-cam sync analysis. Fixed: coerce `channels` to at least 1. + +- **`ColorGradingDelegate` — non-atomic LUT file import** — The `.cube` file was written directly to its destination path via `destFile.outputStream()`. A mid-write failure (disk full, cancelled job) left a partial file at the live path; a subsequent import of the same filename would overwrite it, but any access in between would use a corrupt LUT. Fixed: write to a sibling `.tmp` file first, then `renameTo` (atomic on the same filesystem). Falls back to `copyTo + delete` if rename crosses a mount point. + +### Notes +- No DB schema changes. No new dependencies. No UI changes. +- `.gitignore` already excludes `*.apk`, `CLAUDE.md`, and other local artefacts — no changes needed. + + + +End-to-end hardening sweep across the v3.57 engine scaffolding plus three parallel Explore-agent audits of adjacent subsystems. Landed every real defect found, rejected the false positives with rationale. Net +300 / −15 lines across 8 code files + 4 new test files (+470 lines of tests). Test count 44 → 73. + +### v3.57 engine self-review (fixes to the stubs that shipped yesterday) +- **`SilenceDetectionEngine.DEFAULT_FILLERS`** — removed multi-word entries (`"you know"`, `"i mean"`, `"sort of"`, `"kind of"`). Whisper emits one `WordTimestamp` per whitespace-separated token, so the single-token matcher at [SilenceDetectionEngine.kt:136](app/src/main/java/com/novacut/editor/engine/SilenceDetectionEngine.kt) could never match these entries — they were silently dead code. Added a regression-guard test that fails if anyone adds them back. +- **`SilenceDetectionEngine.detectSilences`** — sample-count math now stays in Long space then clamps to waveform bounds. The prior `(minSilenceMs * sampleRate / 1000L).toInt()` would overflow Int on pathological thresholds (days @ 48 kHz) and surface as a negative-length run, making every sample read "silent". +- **`EquirectangularEngine.Pose`** — NaN/Infinity guards added to `init`. `NaN in -180f..180f` returns true in Kotlin (all NaN comparisons are false, so the range check never fails), so a corrupt JSON Float could have propagated through `poseAt` into every GL uniform. +- **`EquirectangularEngine.poseAt`** — now sorts keyframes internally + uses shortest-arc angular lerp for yaw/roll. Previously a 179° → −179° transition would sweep 358° the wrong way instead of 2° the correct way, and callers had to pre-sort keyframes or get garbage. +- **`AdjustmentLayerEngine.partitionByLayerBoundaries`** — early return on `clipEndMs <= clipStartMs`. Without the guard, a degenerate clip range produced a TreeSet with a single element and `zipWithNext` returned empty — technically correct but easy to regress. +- **`HdrCapabilityProbe.probe`** — `caps.profileLevels` null-guarded. Some OEM / non-standard codec implementations return `null` here and the raw iteration would have NPE'd. +- **`ProjectSyncEngine.addTarget` / `removeTarget`** — CAS-loop replaced the read-modify-write `_flow.value = _flow.value + x` pattern, which could have lost updates under concurrent edits from Settings + a background sync job. +- **`StockAssetEngine`** — removed unused `okhttp3.OkHttpClient` import. + +### Persistence + lifecycle fixes +- **`ProjectArchive.importArchive` InputStream leak** — `mkdirs()` check moved ahead of `openInputStream()`. Previous ordering opened the stream first, so a `mkdirs()` failure (permissions / FS full) would return with an unclosed InputStream. The outer `.use { }` block started three lines later, so any exception between was uncaught by auto-close. +- **`EditorViewModel.onCleared` scrubbing-mode reset** — always calls `videoEngine.setScrubbingMode(false)` now. If the activity dies mid-trim (OS kill, uncaught drag-handler exception), the singleton VideoEngine would otherwise carry the stale scrubbing flag into the next project opened in the same process. +- **`OverlayDelegate.addImageOverlay` stale-playhead snapshot** — reads `playheadMs` / `totalDurationMs` once into locals rather than three separate `stateFlow.value` reads. Previously a playhead scrub between the start and end reads could produce an overlay whose `endTimeMs` didn't line up with its `startTimeMs`. + +### Test infrastructure +- **`testOptions.unitTests.isReturnDefaultValues = true`** added to the Android block. Plain JVM unit tests on code that calls `android.util.Log.*` previously threw `Method X not mocked` instead of returning 0. This was why `SilenceDetectionEngineTest` couldn't reach the assertions on its first run. The setting matches the existing pragmatic-JVM testing approach — instrumentation tests remain the path for anything that legitimately needs the Android runtime. +- **4 new unit-test files** covering the non-stub portions of the v3.57 scaffolding: + - [SilenceDetectionEngineTest.kt](app/src/test/java/com/novacut/editor/engine/SilenceDetectionEngineTest.kt) — 11 tests: empty waveform, zero sample rate, all-silent, all-loud, sub-threshold gap, padding-exceeds-run, overflow guard, filler case-insensitivity, filler padding clamp, no-multi-word-fillers regression guard. + - [AdjustmentLayerEngineTest.kt](app/src/test/java/com/novacut/editor/engine/AdjustmentLayerEngineTest.kt) — 10 tests: no-layers, disabled layer, non-overlap, edge-touch, overlap accumulation, partition with/without layers, invalid-range guard, layer extending beyond clip, zero-duration layer rejection. + - [EquirectangularEngineTest.kt](app/src/test/java/com/novacut/editor/engine/EquirectangularEngineTest.kt) — 9 tests: empty keyframes, before-first / after-last clamp, linear lerp midpoint, unsorted input, yaw wrap-around, EASE_IN shape, NaN / Infinity / out-of-range rejection. + - [AudioMasteringEngineTest.kt](app/src/test/java/com/novacut/editor/engine/AudioMasteringEngineTest.kt) — 7 tests: unique preset IDs, non-empty names, EQ gain/frequency/Q bounds, LUFS / true-peak ranges, compressor ratio sanity, known/unknown preset lookup. + +### False-positive notes (audit-agent findings investigated and left unchanged) +- **`AudioEngine` MediaExtractor leak claim** — `MediaExtractor()` constructor is no-arg and non-throwing; `setDataSource` and everything downstream are inside the outer try, and the finally releases on every path. Agent conflated the constructor with `setDataSource` exposure. +- **`duplicateClip` / `mergeClipWithNext` UUIDs inside CAS lambda** — agent flagged that UUIDs regenerate on retry. They do, but the IDs are not referenced outside the committed state, so the only cost is some wasted UUID allocation per retry. The FINAL committed state always has self-consistent IDs. Safe. +- **`saveProject()` on Main thread** — `viewModelScope.launch {}` without an explicit dispatcher defaults to `Main.immediate`, but Room's suspend DAO functions internally bounce to its own IO pool. No Main-thread DB I/O. +- **`TemplateMarketplaceEngine.setRegistryUrl`** — simple StateFlow value assignment is already atomic (volatile write); no CAS needed. +- **Drawing-mode orphan on forced close** — `dismissedPanelState()` already resets `isDrawingMode = false`, and every panel-open goes through it; back-gesture closure goes through `hideDrawingMode()` which also clears it. No orphan path found. +- **`ProjectAutoSave` silent-drop UX concern** — each drop already logs `Log.w`. Surfacing a user-facing warning when >50% of a track is dropped is a UX improvement, out of scope for this audit — tracked as follow-up. + +### Notes +- No DB schema changes. No new Maven dependencies. No new strings. No behaviour change on valid inputs. +- Full test suite: 73 tests, 0 failures, 0 errors (44 → 73). +- Final `compileDebugKotlin` + `testDebugUnitTest` both green. + +## v3.57.0 — Tier A/B/C Engine Scaffolding + +Scaffolds every remaining engine stub called out in [ROADMAP.md](ROADMAP.md) so each Tier A/B/C item has a concrete file, Hilt-injectable class, typed config/result data classes, and a documented fallback behaviour. Each engine is a drop-in surface: when its dependency lands, only the implementation body changes — ViewModel and UI can start wiring against the surface today. + +Net +1,200 lines across 16 new files. No Maven deps added (keeps APK size and build time unchanged). No UI wiring. Existing stubs (`StabilizationEngine`, `FrameInterpolationEngine`, `UpscaleEngine`, `VideoMattingEngine`, `TapSegmentEngine`, `TtsEngine`, `FFmpegEngine`, `StyleTransferEngine`, `NoiseReductionEngine`, `InpaintingEngine`) are unchanged. + +### Tier A — new stubs +- **`OboeResamplerEngine`** — Oboe-backed sinc SRC for 44.1↔48 kHz mixing. 5 quality levels (linear → 64-point sinc). `isAvailable()` returns false; callers fall back to Media3 resample. +- **`RiveTemplateEngine`** — parallel runtime to `LottieTemplateEngine` for interactive 120 fps animations. 5 built-in template IDs defined; `renderFrame()` returns null until `app.rive:rive-android` is added. + +### Tier C — new engines +- **`StemSeparationEngine`** (C.1) — Demucs v4 htdemucs contract. Returns isolated vocals/drums/bass/other stems as WAV URIs. Model state flow + progress. +- **`SilenceDetectionEngine`** (C.2) — **not a stub** — pure-Kotlin silence detection on the existing waveform path. RMS-threshold run-length scan with configurable padding + min-silence gate. Filler-word detector consumes `SherpaAsrEngine.WordTimestamp` with a 16-word default filler set (`um`, `uh`, `like`, `you know`, …). Returns `CutProposal[]` for the ViewModel to apply as undo-able split+delete commands. +- **`VoiceCloneEngine`** (C.3) — XTTS v2 via Sherpa-ONNX. `VoiceProfile` enrollment from 6 s sample; 16-language synthesis contract. +- **`LipSyncEngine`** (C.4) — Wav2Lip GAN ONNX contract. Tracking-optional face detection, configurable blend strength. Notes Wav2Lip's non-commercial license and flags for pre-release audit of permissive alternatives (MuseTalk, SadTalker). +- **`CaptionTranslationEngine`** (C.5) — NLLB-200 / MADLAD-400 contract. 3 model variants (350 / 600 / 1500 MB). Preserves word timings by proportional redistribution so karaoke-highlight rendering keeps working across translation. +- **`AudioMasteringEngine`** (C.6) — **not a stub** — 5 curated mastering chains (Podcast Voice, Music Master, Dialogue Clean, ASMR, Social Loud) with tuned HPF + EQ bands + compressor + de-esser + noise-reduction mode + EBU R128 target. Pairs with the existing DSP chain — no new DSP code. +- **`StockAssetEngine`** (C.7) — single-interface wrapper for Pexels (video + photo), Pixabay (video + photo), Freesound (SFX), Free Music Archive (music). Attribution string carried per asset. User-supplied API keys. +- **`CameraCaptureEngine`** (C.8) — CameraX + teleprompter contract. 720/1080/4K, front/back, HDR flag, stabilization flag, optional scrolling teleprompter config (WPM, font, mirror, background alpha). +- **`HdrCapabilityProbe`** (C.9) — **not a stub** — live `MediaCodecList` walk classifying HEVC Main10HDR10 / HDR10+ and AV1 HDR profiles across every encoder on the device. Returns supported `HdrFormat` set + capability envelope (max w/h/bitrate). Builds a configured HDR `MediaFormat` with BT.2020 / ST.2084 (or HLG) transfer characteristics. Advisory only — Android 13+ API 33 gated; pre-Tiramisu returns empty. +- **`EquirectangularEngine`** (C.10) — **partially non-stub** — `Pose` data class (yaw/pitch/roll/FOV validated), 3 output projections (equirectangular / rectilinear / little-planet), keyframed-pose interpolation with 4 easings already implemented. GL uniforms return empty until the 360 pipeline is wired. +- **`AdjustmentLayerEngine`** (C.11) — **not a stub** — `AdjustmentLayer` data class with `effectsForClip()` (returns contributing effects by overlap test) and `partitionByLayerBoundaries()` (splits clip range at layer boundaries for per-sub-range effect chains). Consumes existing `model/Effect`. Pairs with a pending `Track`-model extension for storage. +- **`TimelineImportEngine`** (C.14) — inverse of the existing `TimelineExchangeEngine` export. Format auto-detect (`.fcpxml` / `.otio` / `.edl`). `ImportResult` captures dropped effects + unresolved media URIs so the UI can surface lossy conversions before the user commits. +- **`TemplateMarketplaceEngine`** (C.15) — self-hostable registry with documented JSON schema v1. User-configurable registry URL (defaults to `novacut.dev/marketplace/index.json`). Complements the existing `.novacut-template` export/import path from v3.8. +- **`ProjectSyncEngine`** (C.16) — three backends (Syncthing-style LOCAL_FOLDER, SELF_HOSTED HTTP/WebDAV, LAN_PEER over mDNS). `SyncPlan` surfaces LOCAL_AHEAD / REMOTE_AHEAD / DIVERGED state so the UI can offer a real merge dialog instead of silent last-writer-wins clobber. + +### Tier B — tracked (code unchanged this release) +B.1–B.7 are architectural fixes to existing files (Media3 Compositor migration, SmartRenderEngine bypass wire, text-stroke export, ProjectArchive import, etc.) that land per-item in subsequent releases. They remain open in ROADMAP.md with touch-file pointers. + +### ROADMAP +Replaced corrupted 394-line ROADMAP.md (duplicated headers, lost content) with a clean 109-line forward-looking tracker. Tier A has a 13-row table with stub path, Maven coord, model size, and current fallback; Tier B lists 7 limitations with touch-file paths; Tier C lists 16 items grouped by audio/media/timeline/interop with specific engine + panel touch points. Includes dependency-risk notes (OpenCV arm64, FFmpegX maintainer check, Wav2Lip license, model quantisation) and sequencing guidance. + +### Notes +- All new stubs follow the existing stub contract: `@Singleton`, `@Inject constructor`, typed config/result data classes, `isX()` / `isXReady()` query, suspend entry point, `Log.d(TAG, "stub -- ...")` diagnostic. +- Every engine is Hilt-injectable without AppModule changes (constructor-injection discovers them). +- No behaviour change on valid inputs for any existing code path. + +## v3.56.0 — Wide-Net Hardening Pass (Audit Phase 19) + +Four parallel Explore-agent audits covered subsystems that hadn't been looked at in the v3.50 pass: **AI/ML engines**, **audio DSP**, **effects + shaders**, and **exchange/proxy/render**. This release lands every real Critical + all high-value Highs; several agent findings turned out to be false positives (AudioEngine's extractor.release already in outer finally, SegmentationEngine retriever already properly nested) and are noted for the record. + +### GL / shader safety +- **`LottieOverlayEffect`** — every `glGetUniformLocation` now guarded with `if (loc >= 0)` before `glUniform*`, matching the pattern LutEngine + SegmentationGlEffect adopted post-v3.45. Writing to uniform location −1 crashes Mali / Tegra drivers. `glLinkProgram` now checks `GL_LINK_STATUS`; a failed link logs + throws instead of silently producing a corrupt program (Intel / PowerVR render black). +- **`KeyframeEngine.evaluateCubicBezierTime`** — fast-paths to linear interpolation on any non-finite handle (`cp1x/y`, `cp2x/y`) or non-finite input `t`. `coerceIn` does not clamp NaN — every comparison against NaN is false — so a single poisoned handle from a corrupt project JSON would silently NaN-poison every animated property in the clip. +- **`EffectBuilder.buildTransitionEffect` / `buildTransitionOutEffect`** — `transition.durationMs` clamped to `[1, 2_147_000L]` before `* 1000f` to avoid `Float.POSITIVE_INFINITY` at >25-day durations, which poisons the transition shader's progress calculations. + +### Resource safety +- **`SegmentationGlEffect.uploadMaskTexture` / `uploadFallbackMask`** — `GLUtils.texImage2D` wrapped in try/finally so a driver OOM / invalid-format exception can't leak the 260 KB / 4 B bitmap we created immediately before the upload. On long renders this would otherwise accumulate across every failed frame. + +### DSP / math correctness +- **`AudioEngine.mixAudioTracks`** — total-sample arithmetic moved to `Long` before narrowing to `Int`; on timelines >6h 45m at 44.1 kHz stereo the previous `(maxDuration * rate * channels).toInt()` would wrap negative and throw `NegativeArraySizeException` on the FloatArray allocation. Now fails gracefully with an empty mix + warn-log. +- **`LoudnessEngine.applyKWeighting`** — `safeSampleRate` clamped to the practical range `[8_000, 192_000]` instead of `coerceAtLeast(1)`. A bogus 2 Hz from a malformed MediaFormat would have produced a near-1.0 K-weighting `alpha` that effectively disabled the filter. +- **`BeatDetectionEngine.estimateBpm`** — explicit `bestInterval > 0` guard before `60000f / bestInterval`. `coerceIn(30f, 300f)` does not clamp Infinity (Infinity stays Infinity), so pathological input could have leaked an Infinity BPM into downstream UI. +- **`WhisperEngine.runDecoder`** — validates `logits.info.shape.size >= 3` + non-positive dims before indexing. A malformed model output with rank < 3 would otherwise throw `IndexOutOfBoundsException`, leaking every tensor accumulated in the decode loop and aborting transcription silently. +- **`WhisperMel`** — `maxVal` finite-check (empty-spectrum edge case) plus per-sample non-finite guard after normalisation. Previously a corrupt log10 path could NaN-poison the entire spectrogram and make Whisper produce garbage transcriptions instead of a clean empty result. +- **`ColorMatchEngine.analyzeBitmap`** — `w`/`h` hard-capped at 512 each. Tiny-maxDim source (50-pixel composited overlay frame) left `scale = 1f`; a pathological 100-megapixel input would have allocated 400 MB for the histogram. + +### Concurrency +- **`ProxyEngine.generateProxy`** — new per-source-key `Mutex` map serialises concurrent calls for the same `sourceUri`. Previously two near-simultaneous calls both passed the `outFile.exists()` check, both started a Transformer writing to the same `proxy_.mp4`, and the second write corrupted the first. `computeIfAbsent` guarantees one Mutex per key without a coarse-grained map lock. +- **`TtsEngine.synthesize` — `invokeOnCancellation`** — clears the `UtteranceProgressListener` before `engine.stop()`. The `TextToSpeech` engine is effectively a singleton; a stale cancelled-job listener would otherwise fire `onDone`/`onError` into a continuation that already threw `CancellationException`. + +### Security +- **`ProjectArchive.importArchive` ZIP-slip guard** — switched from `outFile.path.startsWith(canonicalTargetDir.path + File.separator)` to `outFile.toPath().startsWith(canonicalTargetDir.toPath())`. The string-prefix check mishandled Windows separators (canonicalTargetDir.path may or may not end with `\`) and was case-sensitive on case-insensitive filesystems. NIO `Path.startsWith` normalises path elements so neither bypass works. +- **`LutEngine.parseCube` / `parse3dl`** — per-line `toFloatOrNull` tolerance. Malformed lines (diagnostic text, commented artefacts from some LUT authoring tools) now skip with a warn-log instead of rejecting the whole LUT via the outer catch. + +### False-positive notes +Four findings were investigated and left unchanged: +- AudioEngine.extractWaveform / decodeToPCM already release the extractor in the outer finally (the "MediaCodec leak on exception" claim conflated decoder lifecycle with extractor lifecycle). +- SegmentationEngine already releases the retriever via properly-nested try/finally — every `return@withContext null` path still runs the finally. +- AiToolsDelegate's `aiJob` race was already mitigated by the identity check documented in the v3.26 audit (`if (aiJob === thisJob)`). +- `OverlaySettings.Builder` on OTIO — `JSONObject.put` already escapes string values. + +### Notes +- No DB schema / dependency changes. No new strings. Net +118 / −22 lines across 11 files. +- Every fix is additive or strictly tightens an existing guard — no behavioural change on valid inputs, defence-in-depth on malformed ones. + +## v3.55.0 — Device-Aware Encoder Capability Probe + +Extends v3.52's pre-flight warning pattern with a real hardware-capability check so users see the warning *before* they burn 40 minutes of render time and hit a Transformer error mid-export. + +### New `EncoderCapabilityProbe` engine helper +- Queries `MediaCodecList.REGULAR_CODECS` for every encoder advertising the selected `codec.mimeType`, then walks each one's `VideoCapabilities` to check whether the user's (width, height, framerate, bitrate) tuple is actually accepted. +- Walks **all** matching encoders so a device with e.g. both Qualcomm hardware HEVC and Google software HEVC is correctly reported as supporting the higher of the two's capabilities. +- Returns a `Capability(supported, reason)` where `reason` is a human-readable string pre-composed for toast / warning display: + - "No HEVC encoder present — falling back to H.264 is safer." + - "HEVC on this device tops out at 1920×1080" + - "HEVC at 3840×2160 is capped to 30 fps on this device" + - "HEVC bitrate is capped at 80 Mbps on this device" +- Silent-safe: if `MediaCodecList` throws (some OEM ROMs do), returns `Capability(supported = true, reason = null)` rather than falsely warning. + +### ExportSheet wiring +- Probe result is `remember`-cached on `(codec, width, height, framerate, videoBitrate)` so repeated recompositions during slider drags don't re-query `MediaCodecList` on every frame. Probe only re-runs when one of those inputs changes. +- When `!probe.supported`, the reason string is appended to the existing pre-flight warnings column alongside the long-render / large-file / AV1-slow warnings from v3.52. + +### Notes +- This is a pre-flight **advisory**, not a guarantee — real-world encoders occasionally refuse configurations they claim to support, and that remains Media3 Transformer's own retry domain. The probe's job is to surface obvious footguns ("4K HEVC on a budget phone") before the render starts. +- No state, no persistence, no new strings (reasons are composed at probe time). +- Complements the existing `ExportConfig.getAvailableCodecs` check (which filters by codec *presence*) with a finer-grained check that the full render spec is acceptable. + +## v3.54.0 — Brand Watermark Burn-in + +First Tier-2 feature lands: image watermark burned into every frame of the exported video via a Media3 `BitmapOverlay`. Composites on-GPU in the same overlay pass as any text overlays, so a project-wide watermark has no extra cost on clips that don't carry text. + +### Model +- New `Watermark(sourceUri, position, opacity, scalePercent)` data class with validation (`opacity ∈ [0,1]`, `scalePercent ∈ [5,50]`). +- New `WatermarkPosition` enum: TOP_LEFT, TOP_RIGHT, BOTTOM_LEFT, BOTTOM_RIGHT, CENTER. +- `ExportConfig.watermark: Watermark?` — null means no watermark, no engine cost. + +### Engine +- New `ExportWatermarkOverlay` object — decodes the user's image via `ContentResolver.openInputStream` once per export, scales to the requested percentage of output frame width (not source width, so the watermark visually fills the same fraction regardless of clip resolution variation), wraps as `BitmapOverlay.createStaticBitmapOverlay` with Media3's anchor system. +- Anchor geometry uses normalised coords with a 7.5% safe-margin offset from the nearest edge (`±0.85` instead of `±1.0`) — matches professional broadcast-safe placement so the watermark never kisses the frame border. +- Silent non-fatal failure: corrupt / unreadable images return null, and the export runs watermark-free rather than erroring out the entire render. + +### Pipeline integration +- `VideoEngine.buildEditedMediaItem` was already building an overlay list per clip for text overlays; refactored to `buildList` and append the watermark (when present) into the same `OverlayEffect`. Single GL pass handles text + watermark together. + +### UI +- New `WatermarkSection` composable inside ExportSheet's Special Outputs section, visible only when `videoModeEnabled` (audio / stems / GIF / contact-sheet exports skip it). +- Image picker (`ACTION_OPEN_DOCUMENT` with `image/*` filter), position chip row, 5%-step opacity slider, 1%-step scale slider (5–50% of output width), and a "Choose a different image" button so users can swap the source without losing their tuned position/opacity/scale. + +### Notes +- No DB schema change. Six new string resources. +- `Watermark.sourceUri` is a `Uri` — persistable read permission isn't taken at the ExportSheet picker here (unlike MediaPicker's video imports) because export runs synchronously in the same session the URI was granted. If a persisted-across-restart watermark is ever needed, wire the launcher through a helper that calls `takePersistableUriPermission`. + +## v3.53.0 — Project Filter Chips + Bulk-Delete Guard + +Two Tier-1 UX wins from the backlog. + +### Project gallery filter chips (§8.2) +- New `ProjectFilterMode` enum (ALL / RECENT_7D / LONG / SHORT / EMPTY). Orthogonal to the existing `SortMode`, so users can e.g. look at "This week" projects sorted by "A–Z". +- `ProjectListViewModel` gains `_filterMode` StateFlow; the `projects` flow now combines four sources (projects + search + sort + filter) so every emission funnels through one consistent filter+sort pipeline. +- `ProjectListScreen` renders a `ProjectFilterChipsRow` directly under the home hero, wrapping via `FlowRow` so the chip set stays reachable on narrow screens without horizontal scroll gestures (which would fight the outer `LazyVerticalGrid`). +- Thresholds: LONG = `durationMs >= 60_000`, SHORT = `1..9_999`, RECENT_7D = `updatedAt >= now - 7d`, EMPTY = `durationMs <= 0`. RECENT_7D is computed inside the combine lambda so `now` is fresh on each recompute. + +### Bulk-delete guard (§1.5) +- `ClipEditingDelegate` now tracks a rolling 10-second window of delete timestamps. On the 3rd delete within the window, raises a one-shot `BulkUndoPrompt` on `EditorState` and clears the window (so a fresh burst has to rebuild the count — no re-fire storm). +- `EditorScreen` renders a Material 3 `Snackbar` keyed on `BulkUndoPrompt.id` with an **Undo** action (calls `viewModel.undo()`) and an 8-second auto-dismiss. The nonce-based key ensures a second burst after the first banner clears actually re-shows. +- New `EditorViewModel.dismissBulkUndoPrompt()` — idempotent, guarded by `id` equality so a stale dismissal from a previous prompt can't clear a newly-raised one. +- No new Snackbar framework — direct Material 3 component with the existing Mocha colour tokens. Future action-snackbars can reuse the same pattern. + +### Notes +- No DB / dependency changes. Three new string resources (`bulk_undo_message/action/dismiss_cd`). +- Filter/sort composition is pure; free-text search applies before the filter chip so "search within subset" works (e.g. "Under 10 s" + search "intro"). + +## v3.52.0 — Export + Import Polish + +Three features from the backlog: extended filename tokens, export pre-flight warnings, and chronological-order import for multi-volume camera footage. + +### Extended filename tokens +- `{duration}` — timeline duration as `MMmSSs` (e.g. `01m34s`). +- `{projectFolder}` — directory-safe flavour of the project name (spaces → `_`, strips everything outside `[A-Za-z0-9._-]`). Doesn't collapse to an empty string — falls back to `{name}` when the sanitized form is blank. +- `{clipCount}` — total clip count across all tracks. +- `{sizeMB}` — post-export token, left literal through the encoder. `ExportDelegate.finalizeFilenameSize` replaces it with the rendered file size in MB and renames on disk after `onComplete`. If the rename fails (e.g., FS collision), falls back to the unrenamed file rather than losing the export. +- Two new presets in the Filename Template picker: "Name + Duration" and "Name + Size". +- `media_picker_audio_only` etc. strings / roadmap descriptions updated to advertise the new tokens. + +### Export pre-flight warnings +- Three static heuristics surface above the Export button in Output Details: + - **Long render** — shown when estimated time ≥ 30 min ("Heads up: estimated render time is … Exports run in the background, but plug in to avoid battery drain.") + - **Large file** — shown when estimated output ≥ 1 GB ("Most share targets reject files this large — consider a Target File Size preset.") + - **AV1 slow** — shown when codec is AV1 ("AV1 is slow on most Android devices. If file size isn't critical, HEVC encodes much faster.") +- Pure computation against the already-resolved `effectiveConfig`; no state plumbing, no persistence. Surfaces on every recomposition so the warning tracks live changes to the config. +- New `estimateExportBytes(totalDurationMs, config)` helper reused by both `estimateExportSize` (for display) and the warning logic (for threshold comparison). + +### Multi-volume sequence ordering on import +- `MediaPicker.sortMediaChronologically(context, uris)` sorts a batch of picked URIs by their resolver `DISPLAY_NAME`, with natural-sort digit padding so camera chapter splits land on the timeline in playback order instead of URI-list order. Wired into both `videoPickerLauncher` (legacy `OpenMultipleDocuments`) and `photoPickerMultiLauncher` (Android 13+ Photo Picker). Non-destructive, silent on no-op batches (`size ≤ 1`). +- Handles the common patterns we see in the wild: GoPro `GH010100.MP4` / `GX010001.MP4`, DJI `DJI_0001.MP4`, Insta360 `VID_20250101_120000_1.MP4`, Samsung `YYYYMMDD_HHMMSS.mp4`, iPhone `IMG_0001.MOV`. The digit-padding approach keeps the comparator cheap (no per-name parser) while matching every format without a bespoke branch. + +### Notes +- No DB schema or dependency changes. +- Four new string resources: the three pre-flight warnings + an updated filename-template description. +- Subtitle encoding auto-detect was investigated and dropped from this release — NovaCut has no subtitle IMPORT path, and the existing export already writes UTF-8. Re-evaluate if/when an import path is added (e.g. for the subtitle-aware scene-cut feature at §6.9 in CROSS-PROJECT-ROADMAP.md). + +## v3.51.0 — Post-Audit Follow-ups + +Lands the three follow-up items flagged during the v3.50.0 hardening pass. + +### Subtitle sidecar sequencing +- `.srt` / `.vtt` / `.ass` subtitle files now written **inside** `ExportDelegate.startExport`'s Transformer `onComplete` block (same pattern as the v3.48 scratchpad sidecar) so they land next to the rendered video with a matching basename and guaranteed ordering before Share / Save-to-Gallery become available. Previously the UI fired `onExportSubtitles` in parallel to `onStartExport`, writing to a separate `externalFilesDir/subtitles/` dir, which meant: (a) the pair didn't travel together through share intents, and (b) a fast Share tap could race the sidecar write. The standalone "Export SRT/VTT" overflow-menu path is unchanged for users who want subtitles without a video export. +- `ExportSheet` Export button no longer fires `onExportSubtitles` — the sidecar is an effect of the video export. + +### Audio picker MIME validation +- Legacy `ACTION_OPEN_DOCUMENT` picker's MIME filter is advisory on several devices. When the audio picker returns a URI, `MediaPicker` now verifies `ContentResolver.getType(uri)` starts with `audio/` (or is `application/ogg`) before routing to the AUDIO track. A mis-routed video or image URI used to be added silently to the audio track and fail playback later. Surfaces a user-facing message ("That file isn't audio. Pick a .mp3, .m4a, .wav, .ogg, or .flac.") via the existing permission-message banner. + +### Managed-media dir GC on project delete +- New `ProjectAutoSave.collectReferencedSourceUris()` — cheap regex scan over every project's auto-save JSON to extract the `sourceUri` of every Clip and ImageOverlay still referenced by a surviving project. Runs under `saveMutex` so a concurrent save can't corrupt the read. Uses regex rather than full deserializer round-trip so it survives forward-compatible model changes and runs in milliseconds across hundreds of projects. +- New `LocalMediaImport.sweepUnreferencedManagedMedia(context, referencedUris, minAgeMs = 24h)` — mark-and-sweep GC over `filesDir/media/imports/`. Files not in the keep-set and older than 24 h are deleted. The 24 h buffer prevents a racing in-flight import (just written, not yet registered in an auto-save JSON) from being swept. Returns `ManagedMediaSweepResult(filesDeleted, bytesFreed)` for telemetry. +- `ProjectListViewModel.deleteProject` now runs the sweep after DB deletion + recovery clear. Previously the managed-media dir grew monotonically — deleting a project removed the row + recovery file but leaked every imported source clip on disk. + +### Notes +- No DB schema changes. No new dependencies. One new string resource. +- `sweepUnreferencedManagedMedia` + `collectReferencedSourceUris` are both new additive APIs; existing call sites untouched. + +## v3.50.0 — Hardening Pass (Audit Phase 18) + +Staff-level audit + refactor pass across the Codex-refactored tree. Four parallel Explore-agent audits produced ~30 findings; this release lands every Critical and all high-value Highs. False-positive findings (speed-curve-aware effect ID remap on duplicateClip, Timeline NaN guard, FileProvider URI revocation risk for PhotoPicker) were evaluated and explicitly left unchanged with rationale. + +### Correctness — speed-curve awareness +- **`Clip.timelineOffsetToSourceMs(timelineOffsetMs)`** (new) — inverse of the forward time mapping used by `durationMs`. Numerical reverse-lookup on the speedCurve (256 linear samples, sub-sample interpolation) when present; falls back to `trimStart + timelineOffset * speed` for constant-speed clips. Clamped to the trim range so callers can never read outside the backing media. +- **Contact-sheet midpoint** (`ContactSheetExporter.kt`) — the thumbnail frame now comes from `clip.timelineOffsetToSourceMs(durationMs/2)` instead of the arithmetic trim midpoint. Ramped clips (e.g. 0.5×→2×) used to grab a misleading frame because the visual midpoint isn't at trim-center. Also: removed an incorrect `bitmap.recycle()` call that would have corrupted `VideoEngine.thumbnailCache` (the cache returns its own bitmap instances; the cache owns their lifecycle). +- **GIF export frame mapping** (`ExportDelegate.kt:234`) — same fix; GIF frames now use `timelineOffsetToSourceMs` so a curved clip exports the correct frames. +- **Split preserves speedCurve** (`ClipEditingDelegate.kt`) — when a clip with a `speedCurve` is split, each half inherits a **remapped sub-range** of the parent curve via the new `SpeedCurve.restrictTo(startFraction, endFraction, clipDurationMs)` helper. Previously both halves kept the full parent curve and misreported speeds across the new trim ranges. +- **`splitPointInSource`** now calls `clip.timelineOffsetToSourceMs(relativePosition)` so the split lands at the correct source frame under curves. + +### Stability — data safety +- **AutoSave mutex coverage** (`ProjectAutoSave.kt`) — `loadRecoveryData` and `clearRecoveryData` are both now `suspend` and wrap their full sequence in `saveMutex.withLock`. Previously `clearRecoveryData` was synchronous and not under any mutex, so a delete racing an auto-save could partially clear one of the three files (`.json`, `.tmp`, `.backup`) and leave a ghost recovery behind. `loadRecoveryData` grew the same guard so rename-in-flight between `saveState`'s temp-write and its atomic rename can no longer race a load to see either the pre- or post-rename half. +- **Trim binary-search iteration cap + monotonicity guard** (`TimelineEditing.kt`) — `trimStartForTimelineStart` / `trimEndForTimelineEnd` now cap at 64 iterations (log₂ headroom for any realistic trim range) and early-return if `clip.durationMs` goes to 0 on a non-zero trim range (symptom of corrupt speedCurve with stale NaN handles coerced in-range). Previously the loop could wedge on a non-monotonic cost function. +- **Recovery dialog is modal** (`EditorScreen.kt`) — `DialogProperties(dismissOnBackPress = false, dismissOnClickOutside = false)`. `onDismissRequest` used to accept the recovery silently on tap-outside, which destroyed users' deliberate intent to discard. Users must now choose Keep or Discard explicitly. +- **Duplicate-project name uniqueness reads a fresh DAO snapshot** (`ProjectListViewModel.kt`) — computes the `(Copy N)` suffix inside the IO coroutine against `projectDao.getAllProjectsSnapshot()` (new DAO query) rather than the potentially-stale `allProjects.value` StateFlow read on the UI thread. Closes a race where two near-simultaneous duplicate taps could mint the same "(Copy)" name. +- **Undo/redo restores playhead** (`EditorViewModel.kt`) — `UndoAction` gains `playheadMs: Long`. Saved in `saveUndoState`, restored (and clamped to the restored timeline's `totalDurationMs`) in `undo()`, `redo()`, and `jumpToUndoState`. Previously an undo of "delete last clip" left the playhead dangling past the new timeline end. + +### Export robustness +- **`resolveTargetSize` on zero duration** pins `bitrateOverride = 500_000` instead of silently falling back to the default quality-based bitrate, which would blow past the user's declared file-size target the moment a clip is added. +- **`gifExportJob` renamed to `nonVideoExportJob`** with a doc comment explaining it holds both GIF and contact-sheet coroutines (and any future non-Transformer export path). +- **Filename-template suffix reserve** (`ExportDelegate.createOutputFile`) — base name budgeted to 58 chars (64 minus a 6-char ` (999)` suffix) so collision retries don't force the base to shrink with every iteration. +- **MediaStore `IS_PENDING` retry** (`ExportDelegate.saveExportedFile`) — up to 3 attempts with 0/100/400 ms backoff before failing. Some devices transiently return 0 rows-updated while a MediaStore indexer run is in flight. +- **`activeExportOutputFile` nulled in outer finally** (`VideoEngine.kt`) — timeout/early-exit paths no longer leave a stale file handle pointer that a subsequent `cancelExport()` would try to delete. + +### Media import +- **Atomic rename pattern** (`LocalMediaImport.importUriToManagedMedia`) — writes to a sibling `.partial` file, renames on success, falls back to stream-copy-and-delete if the rename fails cross-filesystem. An interrupted or crashing copy can no longer surface to the timeline as a truncated-but-valid video. +- **Abandoned-partials sweep** — once-per-import, deletes `.partial` files older than 10 minutes in the managed-media dir. Bounded GC so orphans can't accumulate indefinitely. + +### Notes +- No schema changes. No new dependencies. +- New DAO query `ProjectDao.getAllProjectsSnapshot()` is additive and non-breaking. +- The four audit reports produced ~30 findings; explicit **false-positive** adjudications in this commit: the Timeline pinch-zoom NaN guard was already fully mitigated (safe variables are used throughout the closure), `duplicateClip` already regenerates effect IDs per-invocation (each linked clip gets its own regeneration), `reorderClip` already invokes `recalculateDuration` for cross-track propagation, and `Project.thumbnailUri` points to the source video (deleting it with the project would destroy user footage). These were left unchanged with rationale documented here. + +## v3.49.0 — Contact Sheet Export + +Ships roadmap §8.1 — **contact-sheet export** (FrameSnap-inspired). Renders a single PNG with one thumbnail per clip, labeled and arranged in a configurable grid. Great for review-decks, social-media teasers, and archival of long projects as a single scannable image. + +### ContactSheetExporter engine +- New `engine/ContactSheetExporter.kt` — single-file Kotlin object rendering clips into an ARGB_8888 bitmap via Canvas, compressed to PNG. +- Layout: columns-wide × `ceil(clips/cols)` rows. Per-cell: 320×180 thumbnail + 28 px caption strip with clip label (source filename, truncated to 24 chars) and formatted duration (`M:SS`). Catppuccin-Mocha background (`#1E1E2E`), Text colour for labels, Subtext0 for durations. +- Thumbnails come from `VideoEngine.extractThumbnail()` at each clip's **midpoint relative to trim** — no extra decode pipeline, existing LRU cache accelerates repeated sheet exports. +- OOM-safe allocation guard on the parent bitmap (explicit `OutOfMemoryError` catch returns false rather than crashing). +- Coroutine-cancellable: `ensureActive()` between cells so the Cancel button in ExportSheet works. + +### ExportConfig extensions +- `exportAsContactSheet: Boolean = false` — mode flag. +- `contactSheetColumns: Int = 4` — grid width (UI-clamped to {2, 3, 4, 5, 6}; engine-clamped to [1, 8]). +- Treated as **mutually exclusive** with the other alt-outputs (GIF / audio-only / stems / frame-capture) via the same cascade reset pattern used by the existing toggles. + +### ExportSheet UI +- New toggle row "Contact Sheet" (Mocha.Flamingo accent, `Icons.Default.GridView`) in the Special Outputs section. +- When active: column chip row (2/3/4/5/6) + summary pill "Contact sheet · N columns" + export button label swaps to "Export Contact Sheet". +- Delivery Options + audio codec sections auto-hide when in contact-sheet mode (they're not applicable to a still-image output). + +### ExportDelegate dispatch +- New contact-sheet branch at the top of `startExport` — runs before the GIF branch and before the main Transformer path. Reuses `gifExportJob` coroutine holder for cancel/progress plumbing. +- Filters tracks to VIDEO + OVERLAY (static clips with visual content); skips AUDIO/TEXT tracks. +- Uses `createOutputFile` with a `_contact` suffix on the preferred filename, routed through the existing filename-template expansion. +- PNG output auto-routes to `Pictures/NovaCut/` via the existing `exportUsesImageCollection` check in `saveToGallery()` — no new MediaStore code. + +### Notes +- No DB changes, no new dependencies. Five new string resources. +- Supports aspect-ratio variance across clips — each thumbnail is scaled to 320×180 (16:9 container); portrait footage is letterboxed, not cropped, because thumbnail extraction respects source aspect. +- Known limit: the whole sheet is one bitmap in memory. For a 6-column sheet across 100 clips (16 rows), that's ~13 MB ARGB — comfortably under `largeHeap` budget but would need tiling if users ever push to 500+ clips. + +## v3.48.0 — Preset Grouping + Scratchpad Sidecar + +Builds on v3.47.0. Ships two small Tier-1 wins: roadmap §1.3 preset discoverability and the deferred §6.4 sidecar export. + +### Preset grouping (§1.3) +- **SpeedCurveEditor** — speed presets split into two labeled FlowRows: **Ramps** (Ramp Up, Ramp Down, Pulse) and **Constants** (Slow Mo, 2×, 4×). Previously a single unlabeled row. +- **KeyframeCurveEditor** — dropdown menu divided into three groups with subtle subheaders: **Cinematic** (Ken Burns, Drift, Zoom In/Out), **Fades** (Fade In, Fade Out), **Emphasis** (Pulse, Shake, Spin 360). `HorizontalDivider` + `MaterialTheme.typography.labelSmall` labels between groups. `applyPreset` lambda extracted to keep each group's `DropdownMenuItem` declaration terse. + +### Scratchpad notes sidecar export (§6.4 completion) +- When the project carries a non-blank `project.notes`, export now drops a `.notes.txt` file alongside the rendered video. Runs on `Dispatchers.IO` inside the Transformer `onComplete` callback; failure is logged via `Log.w` but does not affect the export completion state. +- Implementation: `ExportDelegate.startExport` — inline block after the render succeeds, guarded by `currentState.project.notes.isNotBlank()`. + +### Notes +- No model or DB changes. No new dependencies. Five new string resources for preset group labels. +- Release build of v3.47.0 failed mid-assembly when the preset-grouping changes were edited in during R8; v3.48.0 rolls up the fix and those polish items into one clean release. + +## v3.47.0 — Scratchpad Notes + Visible Recovery Dialog (Wave 2 Port) + +Continuation of the cross-project port initiative. Ships two Tier-1 features from [CROSS-PROJECT-ROADMAP.md](CROSS-PROJECT-ROADMAP.md): **Scratchpad notes per project (§6.4)** and **Visible crash-recovery dialog (§1.6)**. + +### Scratchpad +- New `Project.notes: String = ""` field persisted in Room. DB schema bumped to v6 with `MIGRATION_5_6` (`ALTER TABLE projects ADD COLUMN notes TEXT NOT NULL DEFAULT ''`). +- New `ScratchpadSheet` Composable (`ui/editor/ScratchpadSheet.kt`) — free-form notes editor with 180–360 dp OutlinedTextField, yellow Mocha accent, 750 ms-debounced auto-persist via `LaunchedEffect(text)` + `delay()` to avoid hammering Room on every keystroke. +- Wired into EditorScreen overflow menu as "Scratchpad Notes" (Icons.AutoMirrored.Filled.Notes). +- `EditorViewModel.showScratchpad()` / `hideScratchpad()` / `updateProjectNotes(notes)` + new `PanelId.SCRATCHPAD`. Uses existing `saveProject()` for Room persistence. + +### Recovery dialog +- Project open flow in `EditorViewModel` now opens a `PanelId.RECOVERY_DIALOG` whenever `autoSave.loadRecoveryData()` returned non-empty tracks/overlays. Previously the restore happened silently — users had no indication that their project was recovered from a prior-session crash. +- `EditorScreen` renders a Material 3 `AlertDialog` for `RECOVERY_DIALOG`: + - **Keep recovered** (default) — dismisses the dialog; recovered state remains applied and continues to auto-save normally. + - **Discard** — calls `autoSave.clearRecoveryData(projectId)`; the recovery file is removed so the user can reload the Room-persisted baseline by closing and reopening the project. +- `EditorViewModel.dismissRecoveryDialog(recover: Boolean)` handles both paths. + +### Notes +- Two new PanelId entries: `SCRATCHPAD`, `RECOVERY_DIALOG`. +- New strings for scratchpad + recovery dialog in `strings.xml`. +- No new dependencies. + +## v3.46.0 — Cross-Project Feature Port (VideoCrush / FrameSnap / GifText) + +Features ported from sibling projects in the Z:\repos tree. + +### Export +- **Target file size presets** (VideoCrush) — New "Target File Size" section in ExportSheet with preset chips for Discord (8/25/100 MB), Gmail (25 MB), Telegram (50 MB), WhatsApp (16 MB), Twitter (512 MB). Picking a preset computes the video bitrate from `(targetBytes * 8 * 1000 / durationMs) - audioBitrate`, with 2% headroom reserved for mp4 container overhead. Bitrate is clamped to `[500 kbps, 150 Mbps]` and resolved at export dispatch time in `ExportDelegate.startExport` via `ExportConfig.resolveTargetSize(totalDurationMs)` so duration changes after selection are honored automatically. + - `ExportConfig` gains `targetSizeBytes: Long?` (preset marker) + `bitrateOverride: Int?` (resolved value). `videoBitrate` getter returns `bitrateOverride ?: defaultVideoBitrate` so all downstream consumers (VideoEngine, ExportSheet size/bitrate display) automatically reflect the target. +- **Pre-flight export ETA** — Output Details card now shows "Est. time: Xm Ys" above the ready-to-export button, derived from timeline duration × resolution-pixel-ratio × codec factor (H.264=1.0, HEVC=1.6, AV1=2.4, VP9=1.9) × fps factor. Base calibration: 1080p30 H.264 ≈ 1.17× real-time on mid-range Android. Pure display — no behavior change to the encoder. +- **Filename templates with tokens** (AlphaCut / FrameSnap) — New "Filename Template" section with five preset patterns: `{name}`, `{name}_{date}`, `{name}_{date}_{time}`, `{name}_{res}_{fps}`, `{name}_{preset}`. Tokens: `{name} {date} {time} {res} {codec} {fps} {preset}`. Expanded in `ExportDelegate.createOutputFile` via `applyFilenameTemplate` before passing through `sanitizeFileName`. Collision-free numbering (`Name (2).mp4`, `(3).mp4`…) still runs on top of the expanded template. + +### Text overlays +- **Meme-style text templates** (GifText) — Six new entries in `builtInTextTemplates` under the SOCIAL category: Impact Meme (top/bottom text, stroke, condensed), TikTok Caption (black-on-white with slide-up), Reels Hook (glow + bounce "WAIT FOR IT…"), POV Meme (typewriter POV overlay), Neon Glow (blur-in "VIBES"), Word Burst (big single-word elastic pop). All wired to existing `TextAnimation` enum values — no new rendering code required. + +### Notes +- No new dependencies. All changes are local to `ExportConfig`, `ExportSheet`, `ExportDelegate`, `TextTemplateGallery`, and `strings.xml`. +- Target-size resolution runs at dispatch time, so batch-export items with a `targetSizeBytes` set get their bitrate re-derived per timeline duration (safe for the same timeline with different target-size preset queues). + +## v3.45.0 — Audit Phase 17: GL Attrib Guards, DSP NaN Flush, Gesture Robustness + +### GL pipeline safety +- **LutEngine attribute location unchecked** ([LutEngine.kt#L221](app/src/main/java/com/novacut/editor/engine/LutEngine.kt#L221)) — `glGetAttribLocation` returns `-1` when the driver's shader compiler optimizes an attribute away or the linker renames it. Calling `glEnableVertexAttribArray(-1)` and `glVertexAttribPointer(-1, ...)` is undefined behavior: some drivers silently no-op, others corrupt GL state so the LUT render pass outputs black. Now guards both sites with `if (p >= 0)` matching the pattern already used in `ShaderEffect.kt`. +- **SegmentationGlEffect attribute location unchecked** ([SegmentationGlEffect.kt#L262](app/src/main/java/com/novacut/editor/engine/segmentation/SegmentationGlEffect.kt#L262)) — Same pattern. User-reported symptom would be segmented frames rendering fully black during export on certain device GPUs while preview looks correct. + +### DSP / audio integrity +- **Reverb feedback NaN / denormal runaway** ([AudioEffectsEngine.kt#L292](app/src/main/java/com/novacut/editor/engine/AudioEffectsEngine.kt#L292)) — The 4-tap comb filter writes `mono + delayed * feedback * damping` back into the delay buffer with no bound. With `feedback = decay * 0.3f` (~0.6 at default) and a DC-biased or sustained-tone input, the delay lines either saturate into `NaN` (via `Inf * anything`) or sink into denormal floats that tank CPU by 10-100× on ARM. Now each stored sample is clamped to `[-4, 4]`, non-finite values replaced with 0, and sub-1e-20 magnitudes flushed to zero. One pathological clip can no longer poison the reverb state for the rest of the render. +- **WhisperMel Slaney-normalization divide-by-zero** ([WhisperMel.kt#L188](app/src/main/java/com/novacut/editor/engine/whisper/WhisperMel.kt#L188)) — `enorm = 2.0 / (hzPoints[m+2] - hzPoints[m])`. On very-short-audio edge cases or low-sample-rate inputs, adjacent mel points can collapse, denominator → 0, `enorm` → `Infinity`, then the multiply on line 191 poisons the filter bank with `NaN`. Whisper transcription silently produced zero-confidence garbage with no user-visible error. Clamped denominator to `>= 1e-8`. + +### Gesture / UI robustness +- **Timeline pinch-zoom NaN propagation** ([Timeline.kt#L654](app/src/main/java/com/novacut/editor/ui/editor/Timeline.kt#L654)) — `detectTransformGestures` can emit NaN `zoom`/`pan`/`centroid` values on malformed multi-touch events. `coerceIn` does NOT clamp NaN (all NaN comparisons return false), so `newZoom` became NaN, division produced `Infinity`, and scroll offset was permanently corrupted — timeline unusable until the activity was rebuilt. Now `isFinite()`-guards each gesture input and clamps `oldPpm`/`newPpm` denominators to `>= 0.0001f`. +- **DrawingOverlayPanel touch-path NaN abort** ([DrawingOverlayPanel.kt#L171](app/src/main/java/com/novacut/editor/ui/editor/DrawingOverlayPanel.kt#L171)) — A single non-finite touch coordinate (sensor error, gesture-library edge case) in the draw gesture silently aborted the Compose `Path` rendering for the entire drawing layer — every subsequent stroke invisible until editor reload. Matches the v3.44 deserialization-side fix; now also filtered at input time. `onDragStart` / `onDrag` both check `isFinite()`. + +### Audit findings verified as already-correct (false positives this round) +- **Timeline ruler dual `pointerInput` conflict** — Compose's gesture-winner resolution already handles tap-then-drag cooperation correctly; both `detectTapGestures` and `detectDragGestures` on separate `pointerInput` blocks is an idiomatic pattern and field-tested. +- **PreviewPanel `DisposableEffect(engine)` listener leak** — `engine` is a Hilt `@Singleton` so never swaps; the captured-player-reuse pattern in the current code is already correct. +- **AiToolsDelegate concurrent tool race** — `aiJob?.cancel()` runs before the new job launches, and the `finally` block's `if (aiJob === thisJob)` identity check already protects state from stale cancelled jobs. +- **`autoColorCorrect` MediaMetadataRetriever leak on early return** — `retriever.release()` lives in the outer `finally`; early returns inside the `try` still trigger it. +- **`generateEnergyCaptions` divide-by-zero on silence** — Guarded at line 208 with `if (maxEnergy < 0.001f) return@withContext emptyList()` before any of the `/ maxEnergy` sites execute. +- **`LoudnessEngine` K-weighting alpha overflow** — `safeSampleRate` is coerced to `>= 1`, so `hpAlpha` lands in `[0, 1]` for every realistic input. + +## v3.44.0 — Audit Phase 16: Persistence NaN Guards, GIF Overflow, Export Races + +### Persistence hardening +- **ColorGrade / HslQualifier NaN propagation** ([ProjectAutoSave.kt#L962](app/src/main/java/com/novacut/editor/engine/ProjectAutoSave.kt#L962)) — All 22 `liftR/G/B`, `gammaR/G/B`, `gainR/G/B`, `offsetR/G/B`, `lutIntensity`, and the 10 HSL qualifier fields called `.toFloat()` on raw `optDouble` values. A compromised recovery file or manually-edited JSON with `NaN`/`Infinity` propagated directly into the color matrix, turning the entire clip black on playback and export (RgbMatrix multiplies NaN across every channel). New `safeFloat()` helper coerces each field to its identity default when non-finite, plus `lutIntensity` clamped to `[0,1]`. Same pattern applied to `CurvePoint` bezier handles (were previously trusted raw, corrupting color curves on bad input). +- **ImageOverlay `require(startTimeMs < endTimeMs)` dropped overlay on recovery** ([ProjectAutoSave.kt#L309](app/src/main/java/com/novacut/editor/engine/ProjectAutoSave.kt#L309)) — Corrupt JSON with equal or inverted time bounds threw in the constructor, the try/catch silently swallowed the exception, and the whole overlay vanished — silent data loss on every recovery cycle. Now coerces `endTimeMs = max(startTimeMs + 1, rawEnd)` before constructing, with `isFinite()` guards on `positionX/Y`, `scale`, `rotation`, `opacity` so NaN coordinates can't corrupt placement math. +- **DrawingPath NaN coordinates break Compose Canvas** ([ProjectAutoSave.kt#L346](app/src/main/java/com/novacut/editor/engine/ProjectAutoSave.kt#L346)) — A single non-finite `x` or `y` in a drawing path caused `drawPath` to silently abort rendering for the entire drawing layer (every subsequent path invisible). Now filters non-finite points per path, rejects paths with <2 remaining points, and clamps `strokeWidth` to `[0.5, 64]dp`. +- **Caption word timings escaped caption bounds** ([ProjectAutoSave.kt#L1105](app/src/main/java/com/novacut/editor/engine/ProjectAutoSave.kt#L1105)) — `CaptionWord.endTimeMs > Caption.endTimeMs` silently broke the karaoke-highlight renderer which assumes sorted, in-bounds words. Now filters words that start past the caption window and clamps `endTimeMs` to the caption's end. `CaptionStyle.fontSize` / `positionY` get NaN guards plus `positionY ∈ [0,1]`. +- **copyAutoSave read/write race** ([ProjectAutoSave.kt#L109](app/src/main/java/com/novacut/editor/engine/ProjectAutoSave.kt#L109)) — `saveMutex` was released between reading the source JSON and writing the renamed copy. A concurrent auto-save of the source project during that gap let the duplicate capture stale data (source would have newer edits than the "duplicate"). Now holds the mutex across the full read→mutate→write sequence. + +### Export +- **GIF export frame-count `toInt()` truncation** ([ExportDelegate.kt#L109](app/src/main/java/com/novacut/editor/ui/editor/ExportDelegate.kt#L109)) — `(totalDurationMs / frameIntervalMs).toInt().coerceIn(1, 300)` narrowed to `Int` before clamping. A pathologically long `totalDurationMs` (duration-math bug or corrupt state) divided by a 1 ms interval exceeded `Int.MAX_VALUE`, `.toInt()` wrapped negative, and `coerceIn` then clamped to 1 — silently skipping export instead of capping at 300 frames. Now clamps in `Long` space before narrowing: `.coerceIn(1L, 300L).toInt()`. + +### Diagnostics +- **ProjectAutoSave.release() silently swallowed temp-file sweep failures** ([ProjectAutoSave.kt#L138](app/src/main/java/com/novacut/editor/engine/ProjectAutoSave.kt#L138)) — Added `onFailure { Log.w(...) }` so an I/O or permission fault during orphan cleanup is surfaced in logcat rather than silently accumulating `.tmp` files across process lifetimes. + +## v3.43.0 — Audit Phase 15: Version Drift, FCPXML Rounding, Lottie GL Safety + +### Build integrity +- **`NovaCutApp.VERSION` drifted three releases** ([NovaCutApp.kt#L24](app/src/main/java/com/novacut/editor/NovaCutApp.kt#L24)) — The `VERSION` constant was hard-coded to `"v3.39.0"` while the gradle `versionName` was `"3.42.0"`. Model downloads advertised the stale version in their `User-Agent`, the about dialog misreported the build, and any future crash-reporting integration would have mis-tagged reports. Now sourced from `BuildConfig.VERSION_NAME` so it can't drift again; added `buildConfig = true` to `buildFeatures` to enable the generated field. + +### FCPXML / OTIO round-trip +- **`msToFcpxmlTime` truncation drift** ([TimelineExchangeEngine.kt#L548](app/src/main/java/com/novacut/editor/engine/TimelineExchangeEngine.kt#L548)) — The sibling `msToFrames` / `framesToMs` helpers were already using round-to-nearest (fixed in phase 9), but the FCPXML-specific `msToFcpxmlTime` still truncated, so a 33 ms offset at 30 fps emitted `0/30s` instead of `1/30s`. Cumulative drift on a long timeline misaligned clip offsets and asset start/duration when round-tripped through Final Cut Pro or DaVinci Resolve. Now symmetric with the other two: `(ms * frameRate + 500L) / 1000L`, plus a `frameRate <= 0` guard that emits a safe fallback token instead of a divide. + +### GL resource safety +- **Lottie texture upload bitmap leak on GL exception** ([LottieTemplateEngine.kt#L138](app/src/main/java/com/novacut/editor/engine/LottieTemplateEngine.kt#L138)) — `renderFrameToTexture` only recycled its bitmap on the happy path and on the `glGenTextures == 0` guard. If `GLUtils.texImage2D` threw (OOM, context lost, bad format), both the bitmap and the freshly-generated texture ID leaked. Animated-title exports push tens of bitmaps per second through this function; one bad frame per export would still be fine, but any repeated driver failure cascaded into a visible OOM. Now wrapped in try/catch that deletes the texture and recycles the bitmap before re-throwing. + +### Audit findings verified as already-correct (false positives this round) +- **TimelineExchangeEngine other timecode math** — `msToFrames` / `framesToMs` already use the rounding form with `frameRate <= 0` guards from phase 9. +- **FirstRunTutorial `tutorialStepDefs[step]` out-of-bounds** — `currentStep++` only runs when `!isLastStep`, so the index stays in `0..size-1` for a hard-coded non-empty list. Safe. +- **RenderPreviewSheet ratio divide** — The `if (summary.totalDurationMs > 0L)` guard already wraps the divide; `segments.isEmpty()` doesn't influence the computation. +- **SnapshotHistoryPanel `SimpleDateFormat` thread-safety** — The `remember`-d formatter is only consumed from the composable's recompose pass, which runs on the main thread; it never crosses to a background coroutine. +- **`-dontwarn org.bouncycastle.**` "unused dependency"** — OkHttp references bouncycastle / conscrypt / openjsse as *optional* TLS providers; the warning suppression is needed at link-time even though the classes aren't packaged. +- **EffectShareEngine LUT filename collision** — Effect exports intentionally reference LUTs by filename only (they don't embed the binary); cross-project namespacing would break the whole sharing feature. Documented as a known limitation of the export format. + +## v3.42.0 — Audit Phase 14: Speed Curve NaN, Deserialization Bounds, Graph Cycles, Flow Churn + +### Speed curve math +- **NaN in harmonic mean → zero-duration clip** ([Project.kt#L143](app/src/main/java/com/novacut/editor/model/Project.kt#L143)) — `coerceAtLeast(0.01f)` preserves NaN (comparisons with NaN are false, so the branch that would clamp never fires), so one NaN speed sample poisoned `sumReciprocal`, the harmonic mean returned NaN, and `Clip.durationMs` silently collapsed to 0 — the clip disappeared from the timeline with no error surface. Now explicitly checks `isFinite()` on both the per-sample speed and the final `sumReciprocal` and falls back to the static `speed` field. + +### Deserialization hardening +- **SpeedCurve control-point bounds** ([ProjectAutoSave.kt#L1002](app/src/main/java/com/novacut/editor/engine/ProjectAutoSave.kt#L1002)) — The auto-save parser accepted any `Double` for `position`/`speed`/`handleInY`/`handleOutY`. A corrupted file with `speed = -0.5` or `position = 5.0` passed straight into bezier evaluation and the harmonic-mean divide. Now all four fields are `isFinite()`-checked and clamped to sensible ranges (`position ∈ [0,1]`, speeds ∈ `[0.01, 100]`), matching the UI-side invariants. +- **Self-referencing `linkedClipId`** ([ProjectAutoSave.kt](app/src/main/java/com/novacut/editor/engine/ProjectAutoSave.kt)) — The orphaned-reference cleanup on load checked `linkedClipId !in allClipIds` but not `linkedClipId == clip.id`. A clip linking to itself would create an infinite loop in any traversal that followed the chain (slip-link propagation, group moves). Now both conditions null the link. +- **Compound clip serialization cycle** ([ProjectAutoSave.kt](app/src/main/java/com/novacut/editor/engine/ProjectAutoSave.kt)) — `serializeClip` recursed into `clip.compoundClips` without a depth guard. A corrupted graph where a compound clip eventually cycled back to itself would `StackOverflowError` the whole auto-save coroutine (and every subsequent save, since the state stays corrupted). Added a depth counter (limit 8) that emits a shallow representation and a WARN log above the threshold. + +### Data layer performance +- **Project list Flow re-emits on unrelated updates** ([ProjectListViewModel.kt](app/src/main/java/com/novacut/editor/ui/projects/ProjectListViewModel.kt)) — Room's `Flow>` emits on every write to the `projects` table, even when the query result is bit-identical. The downstream combined flow then forced the grid (and every project card, each with a `VideoFrameDecoder` render) to recompose. Added `.distinctUntilChanged()` on the DAO flow upstream of the combine. + +### Settings robustness +- **SettingsRepository over-broad catches** ([SettingsRepository.kt#L78](app/src/main/java/com/novacut/editor/engine/SettingsRepository.kt#L78)) — Three `enumValueOf` sites caught `Exception`, which masks real defects (OOM wrapped errors, reflection failures). Narrowed to `IllegalArgumentException`, matching the style already used in the write path. + +### Audit findings verified as already-correct (false positives this round) +- **`settings_show_waveforms_desc` / `settings_snap_beat_desc` / `settings_snap_markers_desc` missing** — All three (and the default-track-height description) are defined in `strings.xml:1131-1138`. `R` references resolve. +- **`Project.aspectRatio` / `frameRate` / `resolution` not serialized** — These fields live on the Room `@Entity Project`, not on `AutoSaveState`. They're persisted by Room's `projectDao.updateProject()` call path; the auto-save JSON is deliberately scoped to track/clip/overlay state. +- **`KeyframeEngine` Newton-Raphson slope = 0** — The `if (abs(currentSlope) < 1e-5f) break` line comes **before** the division that would produce `Inf`, not after. No divide-by-zero possible. +- **`evaluateCubicBezierTime` return > 1** — The function exposes `cp1y/cp2y.coerceIn(-1f, 2f)` on purpose for spring/back easing overshoot; clamping here would remove a feature, not fix a bug. +- **`AudioEngine.extractWaveform` "silent audio renders at max height"** — `maxAmplitude` starts at `1f` and is only overwritten when a sample exceeds it; for all-zero PCM the normalization is `0f / 1f = 0f`, not `1f`. Agent misread the init. +- **`Caption.endTimeMs` silent repair** — The auto-fix-on-invert behavior is correct; losing a caption because one bad `endTimeMs` is worse than nudging it. Not worth adding noise-level logging for. + +## v3.41.0 — Audit Phase 13: GL Hardening, Shader Input Bounds, Volume Envelope Safety + +### GL / Shader pipeline +- **LUT intensity NaN poisoning** ([LutEngine.kt](app/src/main/java/com/novacut/editor/engine/LutEngine.kt)) — `LutGlEffect` accepted any `Float` for `intensity` and fed it directly to `glUniform1f`. A NaN intensity (from a corrupted keyframe, a divide-by-zero in the UI slider path, etc.) poisons the `mix(original, graded, uIntensity)` step in the shader and produces NaN pixels across the entire frame. Now clamped to `[0, 1]` with a finite-check fallback at the engine boundary. +- **LUT 3D texture exceeds device capability** ([LutEngine.kt](app/src/main/java/com/novacut/editor/engine/LutEngine.kt)) — Parser caps LUT size at 256, but GLES 3.0 only guarantees `GL_MAX_3D_TEXTURE_SIZE >= 256`. Some lower-tier GPUs report smaller values; `glTexImage3D` then silently fails and `drawFrame` draws black frames with no error surface. Now queries `GL_MAX_3D_TEXTURE_SIZE` at setup and throws a clear `RuntimeException` if the LUT won't fit, letting the error bubble to the UI with a usable message. +- **Segmentation mask texture never initialized** ([SegmentationGlEffect.kt](app/src/main/java/com/novacut/editor/engine/segmentation/SegmentationGlEffect.kt)) — `setupGl()` generated the mask texture handle but never defined its storage. On drivers that require `glTexImage2D` to mark a texture "complete", the first frame's sampler read returned zero (fully masked-out / black output) or hard-failed the draw entirely. Now seeded with a 1×1 `R8` opaque pixel and configured with linear + clamp-to-edge so the first frame is safe regardless of how fast or slow ML inference arrives. +- **Chroma key input bounds** ([ShaderEffect.kt](app/src/main/java/com/novacut/editor/engine/ShaderEffect.kt)) — `smoothstep(uThreshold, uThreshold + uSmoothing, dist)` with `uSmoothing == 0` has undefined GLSL behavior (edge0 == edge1) and produces NaN alpha on some drivers. Also clamped `uKeyR/G/B`, `uThreshold`, `uSpill` to `[0, 1]` — out-of-range RGB values were producing wild keying results when a param slider overshot during a fast drag. + +### Timeline +- **Volume envelope divide-by-zero on zero-duration clip** ([Timeline.kt:1046](app/src/main/java/com/novacut/editor/ui/editor/Timeline.kt#L1046)) — The audio volume envelope path renderer gated on `volumeKfs.size >= 2` but not on `clip.durationMs > 0`. A pathological zero-duration audio clip (possible via rapid trim collision) then hit `kf.timeOffsetMs.toFloat() / clip.durationMs` = `Infinity`, and `drawCircle(... Offset(Infinity, ...))` ANR'd the render thread on some devices. Now guards both conditions. + +### Stub engine defensive tightening +- **SmartReframeEngine EMA divergence** ([SmartReframeEngine.kt](app/src/main/java/com/novacut/editor/engine/SmartReframeEngine.kt)) — `smoothCropTrajectory` accepted any `alpha`. An `alpha > 1` overshoots the target and produces an oscillating/divergent EMA, and `NaN` corrupts every subsequent element via the feedback term. Now coerced to `[0, 1]` with NaN fallback to 0.08, and the single-element edge case is returned unchanged (previously it allocated a new list pointlessly). + +### Audit findings verified as already-correct (false positives this round) +- **ChromaKey shader division-by-zero on `uSpill = 0`** — The shader uses `max(r, b) * (1.0 - uSpill * 0.5)` (multiplicative), not division. No DBZ path exists. +- **WhisperEngine encoder/decoder tensor leak on empty output** — `runEncoder` and `runDecoder` use `firstOrNull()?.value as? OnnxTensor`, not `first()`, and both have `finally` blocks that close `results`/`inputTensor`/`idTensor`. No leak. +- **VideoEngine `SpeedProvider` boundary math** — `coerceIn(0.1f, 100f)` is applied to the *returned* value, which is the correct place; the callee's curve evaluation result cannot escape the clamp. +- **MainActivity intent scheme validation** — Already restricted to `content://` + `video/*` MIME + `openAssetFileDescriptor` read-test in try/catch. Authority whitelisting would reject legitimate third-party content providers (MediaStore URIs come from system providers, not the app). +- **Volume keyframe dot at `clip.keyframes` path** — Already guarded by `if (clipDuration <= 0) return@Canvas` above the divide. +- **`Clip` min-duration invariant** — `require(trimEndMs >= trimStartMs)` permits equality by design; the UI layer enforces the practical 100 ms floor in trim handlers, which is the right layer for that policy (lets non-visual markers / audio cue clips exist). +- **TapSegmentEngine confidence bounds** — Data class is only constructed by unimplemented stub paths; adding `require()` here would throw at runtime if a future backend produced a `0.99999999` edge value due to float drift. Deferred until the engine is wired. + +## v3.40.0 — Audit Phase 12: Export Progress, GIF Safety, AI Job Race, DSP NaN Guards + +### Export pipeline +- **Export progress notification stuck between runs** ([ExportService.kt](app/src/main/java/com/novacut/editor/engine/ExportService.kt)) — `lastNotifiedProgress` persisted across exports, so the throttle `progress - lastNotifiedProgress < 2` silently dropped every update from the second export until it caught up past the previous run's value. The progress bar sat frozen at 99% for the entire second export. Now reset on each `startObservingExport()`, and the throttle is one-sided so backward jumps always publish. +- **GIF export zero-height crash** ([ExportDelegate.kt#L120](app/src/main/java/com/novacut/editor/ui/editor/ExportDelegate.kt#L120)) — `createScaledBitmap(bitmap, maxWidth, 0, true)` throws `IllegalArgumentException` and aborts the whole GIF export on any frame where `bitmap.height * ratio` rounded to `0` (very short source videos or 1-pixel-tall thumbnails). Now bitmaps are skipped when width/height is ≤ 0, and the computed height is floored at 1. +- **ExportTextOverlay NaN poisoning** ([ExportTextOverlay.kt](app/src/main/java/com/novacut/editor/engine/ExportTextOverlay.kt)) — A corrupted keyframe feeding `NaN` into `positionX/Y/scale/rotation` would produce a NaN-poisoned transform matrix that the GL pipeline rejects mid-export with an opaque "framework error". Added `isFinite` guard that silently parks the overlay off-screen for one frame rather than aborting the render. +- **ExportSheet blank error body** ([ExportSheet.kt#L295](app/src/main/java/com/novacut/editor/ui/export/ExportSheet.kt#L295)) — An empty-string `errorMessage` (non-null but blank) rendered the error card with a missing body. Now falls back to the localized generic error when blank. + +### ViewModel / state correctness +- **AI tool cancellation race** ([AiToolsDelegate.kt](app/src/main/java/com/novacut/editor/ui/editor/AiToolsDelegate.kt)) — Tapping a second AI tool while another was running published the new `aiProcessingTool` state **before** cancelling the old job; the old job's `finally` block then fired asynchronously and cleared the state to `null`, hiding the progress indicator for the active tool. Now cancels the previous job first, and the `finally` only clears state when it is still the active job. +- **detectBeats missing undo** ([AudioMixerDelegate.kt](app/src/main/java/com/novacut/editor/ui/editor/AudioMixerDelegate.kt)) — Auto beat detection replaced manually-tapped beat markers without saving undo state, so a user who ran auto-detect to "check" results and got bad ones had no way back. Now records undo before the destructive replacement. + +### DSP correctness +- **Biquad Q → NaN** ([AudioEffectsEngine.kt](app/src/main/java/com/novacut/editor/engine/AudioEffectsEngine.kt)) — `lowPassCoeffs` / `highPassCoeffs` / `peakEqCoeffs` divide `sin(w0) / (2 * q)`; a `q == 0` slider value (or corrupted parameter) produced `alpha = ±Infinity`, which poisoned every coefficient with NaN and — because the IIR state machine feeds outputs back into itself — permanently corrupted every subsequent sample for the rest of the buffer. Q now floored at `0.01f` at the coefficient source. +- **LoudnessEngine short-clip short-term max** ([LoudnessEngine.kt](app/src/main/java/com/novacut/editor/engine/LoudnessEngine.kt)) — For clips shorter than ~3 seconds we have fewer than 8 loudness blocks; the `for (i in 0..size - 8)` loop then iterates over an empty range (negative upper bound becomes an empty `IntRange`), leaving `shortTermMaxLufs = -70f` regardless of actual loudness. Voiceovers and SFX showed up as silent in the loudness meter. Now falls back to `momentaryMax` when there aren't enough blocks for the 3 s window. Also coerced `sampleRate` in the K-weighting filter so a corrupt `sampleRate = 0` can't produce `Infinity/NaN` filter state. + +### Persistence hygiene +- **Auto-save temp file orphans** ([ProjectAutoSave.kt](app/src/main/java/com/novacut/editor/engine/ProjectAutoSave.kt)) — `release()` cancelled the save scope but didn't sweep any `.tmp` files left by interrupted writes; across many app lifetimes these can accumulate in `filesDir/autosave/`. Now `release()` sweeps `*.tmp` after cancelling the scope. + +### Audit findings verified as already-correct (false positives this round) +- **PreviewPanel `DisposableEffect` null player** — `VideoEngine.getPlayer()` returns a non-nullable `ExoPlayer` that is lazily instantiated; `addListener(listener)` cannot receive null. +- **`EditorViewModel.setClipLabel` undefined `rebuildTimeline()`** — `rebuildTimeline()` exists on the ViewModel as a thin alias for `rebuildPlayerTimeline()`; no missing symbol. +- **`ColorGradingDelegate.setClipLut` undo-before-null-check** — `saveUndoState` is already called **after** the `getSelectedClip() ?: return` guard. +- **`ExportService` `lastNotifiedProgress` non-volatile** — The collect pipeline is pinned to `Dispatchers.Main.immediate` and `updateProgress` runs only from that flow, so the field is single-threaded. +- **`VoiceoverRecorderEngine` state race** — `startRecording` / `stopRecording` / `release` are all `@Synchronized`. +- **`HttpURLConnection.disconnect()` missing in download engines** — All three (Whisper, Segmentation, Inpainting) already call `disconnect()` in `finally` from prior audit phases. +- **ProjectAutoSave `beatMarkers` round-trip data loss** — Omitting the field on empty and defaulting to empty on read is symmetric; non-empty lists are always written and read back faithfully. + +## v3.39.0 — Audit Phase 11: Speed Curve Duration Math, Snap Threshold Floor, Tool Grid Recomposition + +### Math correctness +- **Variable-speed clip duration** ([Project.kt#L143-L162](app/src/main/java/com/novacut/editor/model/Project.kt#L143)) — `Clip.durationMs` was averaging the speed curve arithmetically and dividing trim range by the result. Wall-clock duration is the integral of `dt_source / speed(t)`, so the *harmonic* mean of speed is what scales trim range to real time. A clip with the first half at 0.5x and the second half at 2.0x (true duration = 1.25× source) was reporting 0.8× source — the timeline displayed it 56% shorter than it would actually play, and clip stacking math used the wrong endpoint. Now sums reciprocals: `samples / sum(1/speed)`. + +### Timeline UX +- **Snap threshold floor at extreme zoom** ([Timeline.kt#L1342](app/src/main/java/com/novacut/editor/ui/editor/Timeline.kt#L1342)) — `snapThresholdMs = (8.dp.toPx() / pixelsPerMs).toLong()` rounded to `0L` once `pixelsPerMs > snapPx` (very high zoom-in), which silently disabled magnetic snapping for fine-grained edits — the worst time to lose snapping. Now floored at `1L` so the snap window is always at least one millisecond wide. + +### Compose performance +- **Tool sub-menu grid skipping** ([ToolPanel.kt#L498-L508](app/src/main/java/com/novacut/editor/ui/editor/ToolPanel.kt#L498)) — `SubMenuGrid` items were composing `Modifier.then(if (!isDisabled) Modifier.clickable { ... } else Modifier)` per recomposition. The conditional `then(...)` produced a fresh modifier chain (and a fresh click lambda) on every parent recompose, defeating Compose's modifier reuse / clickable click-listener stability. Switched to the standard `Modifier.clickable(enabled = !isDisabled)` form and replaced the parallel `then(Modifier.alpha(...))` with a direct `alpha()` call. Tool grid no longer re-allocates click semantics every time the bottom-tool area re-renders. + +### Audit findings verified as already-correct (false positives this round) +- **EffectBuilder anchor-Y sign flip** — pre-anchor `(-ax, +ay)` and post-anchor `(+ax, -ay)` look inconsistent at first glance but are actually internally consistent: the model exposes Y-up coordinates while `android.graphics.Matrix` is Y-down, so the `+ay`/`-ay` pair correctly translates the anchor to origin and back in matrix space, matching the `(+px, -py)` Y-flip on the position translation. +- **LoudnessEngine short-term loop bounds** — `0..size - shortTermBlocks` (inclusive) with `subList(i, i + shortTermBlocks)` is in-range because `subList`'s `toIndex` is exclusive; the last iteration takes `subList(size - shortTermBlocks, size)`. +- **EdlExporter timecode overflow** — `ms` is `Long`, so `ms * fps + 500` auto-promotes to Long; no Int overflow possible. +- **NoiseReductionEngine soft-gate energy init** — `energy` is initialized at the top of the gate branch (`var energy = 0f`); the `/1f` divisor is cosmetic but mathematically harmless. +- **VideoEngine listener cleanup** — `VideoEngine` is `@Singleton` so the captured `StateFlow` references in the Transformer listener live for app lifetime regardless; no leak. +- **TemplateManager path traversal** — `normalizeImportedTemplate` already mints a fresh UUID when `sanitizedId != template.id`, so `../../etc/passwd` → `etcpasswd` → mismatch → UUID; the path-traversal vector is closed. +- **MediaPicker `Uri.fromFile` exposure** — the file:// URI is consumed only by ExoPlayer/Coil internally and never crosses an app boundary via Intent; no `FileUriExposedException` risk in current code paths. + +## v3.38.0 — Audit Phase 9: FCPXML Escaping, LUT Bounds, Settings Slider Debounce, Template Path Traversal & OTIO Rounding + +### Format / parser correctness +- **FCPXML XML escaping** ([TimelineExchangeEngine.kt](app/src/main/java/com/novacut/editor/engine/TimelineExchangeEngine.kt)) — Project name and clip names were interpolated directly into FCPXML attributes via Kotlin string templates with no escaping. A clip named `M&M's ` produced malformed FCPXML that DaVinci Resolve / Final Cut imports refused. Added `xmlEscape` helper covering `&`, `<`, `>`, `"`, `'` and applied to every name/uri interpolation. +- **OTIO/FCPXML timestamp rounding** — `msToFrames` and `framesToMs` were truncating instead of rounding-to-nearest. 1 ms at 30 fps became 0 frames, accumulating drift on long timelines and breaking round-trip precision. Now uses `(ms * frameRate + 500L) / 1000L` rounding (and the symmetric form for the reverse). +- **LUT size bounds** ([LutEngine.kt](app/src/main/java/com/novacut/editor/engine/LutEngine.kt)) — `parseCube` and `parse3dl` accepted any integer for `LUT_3D_SIZE`. A malicious `.cube` declaring `LUT_3D_SIZE 1000` would attempt a `1000³ × 3 = 3 billion` float allocation (~12 GB) and OOM the app before the row-count validation could reject it. Now bounded to `[2, 256]` (covers all real-world LUTs: 17, 32, 33, 64). +- **LUT value clamping** — Both `.cube` and `.3dl` parsers now `coerceIn(0f, 1f)` each color channel. Out-of-range entries previously produced wild GPU colors (negative wraps, >1 blows out highlights) on shaders that assume normalized inputs. + +### Security / template safety +- **TemplateManager template-id sanitization** — Imported template ids were used directly as filename via `File(templateDir, "$id.json")`. A hostile `.novacut-template` with id `../../etc/passwd` would land outside the template directory (path traversal). `normalizeImportedTemplate` now sanitizes ids to `[A-Za-z0-9_-]` and mints a fresh UUID when sanitization changes the value. + +### Settings UX +- **Settings slider disk thrash fix** ([SettingsScreen.kt](app/src/main/java/com/novacut/editor/ui/settings/SettingsScreen.kt)) — `SettingsSlider` was calling `viewModel.set...(it)` (which writes to DataStore) on every drag tick (~60 events/sec). Auto-save-interval drag could fire 100+ DataStore writes in 2 seconds. Refactored to drive a local `mutableStateOf` during drag and only commit via `onValueChangeFinished`. The settings value still flows from DataStore Flow on first composition (and any external change). + +### Audit findings verified as already-correct (false positives this round) +- **`ProjectArchive` zip-bomb compression ratio** — `copyWithLimit` already enforces the 4 GB total cap incrementally as bytes are read; an entry that would decompress past the cap throws mid-read, not after. The cap is reasonable. +- **`SpeedCurveEditor` Y-clamp on drag** — outer `coerceIn(minSpeed, maxSpeed)` already bounds the final speed value even when intermediate Y math is negative; `size.height = 0` (the only NaN path) doesn't fire pointer events anyway. +- **`KeyframeCurveEditor` selection by data-class equality** — Kotlin data class `equals` compares all fields, so `keyframe == selectedKeyframe` works as intended for the editor's purposes; only matters if two keyframes have identical fields, which the deserialize-time `distinctBy { (timeOffsetMs, property) }` prevents. +- **Tier 3+ engine resource leaks (Stabilization, FrameInterp, Style, Upscale, etc.)** — confirmed all stubs return `null` cleanly with `Log.w` messages, never fake objects; ONNX-using engines (Inpainting) properly use try/finally for sessions and tensors. +- **Build / dependency / ProGuard audit** — clean; all critical security versions current (Hilt 2.53.1, Coil 2.7.0, Media3 1.9.2, Kotlin 2.1.0, AGP 8.7.3); minification on release only; signing externalized; permissions audit passes. +- **MultiCamEngine cross-correlation IOOB** — already guarded by `if (length <= 0) return 0f` inside the loop. + +### Verification +- `./gradlew compileDebugKotlin` passes. + +### Housekeeping +- `versionCode 98 → 99`, `versionName 3.37.0 → 3.38.0` (build.gradle.kts, NovaCutApp.VERSION, README badge, app_version string, CLAUDE.md, MEMORY.md). + +## v3.37.0 — Audit Phase 8: TTS/Voiceover Persistence, Camera Cleanup Directory, Empty-Output Guard & Reverse-Clip Diagnostic + +### Persistence +- **`addClipToTrack` (TTS / voiceover helper) now persists** ([EditorViewModel.kt:2116-2152](app/src/main/java/com/novacut/editor/ui/editor/EditorViewModel.kt#L2116-L2152)) — The private 3-arg helper used by both TTS synthesis and voiceover record was missing both `rebuildPlayerTimeline()` and `saveProject()`. Worst case, a freshly recorded voiceover or TTS clip (and any auto-created AUDIO track holding it) would be lost on app crash before the next 30-second auto-save tick. Also rejects `durationMs <= 0` up front so a TTS file with no reported duration can't violate `Clip.init`'s `trimEndMs <= sourceDurationMs` invariant. Removed the now-redundant explicit `rebuildTimeline()` + `saveProject()` calls at the TTS callsite. + +### Resource hygiene +- **MediaPicker camera cleanup pointed at the right directory** ([MediaPicker.kt:151-162](app/src/main/java/com/novacut/editor/ui/mediapicker/MediaPicker.kt#L151-L162)) — Camera capture saves files to `filesDir/media` (line 125), but the LaunchedEffect cleanup was scanning `cacheDir/camera` — a path that doesn't exist in this app. Result: orphaned recordings from app crashes, force-stops, or the user backing out of the camera mid-record were never cleaned up and accumulated indefinitely. Now scans the correct directory and tolerates `delete()` failures. + +### Export integrity +- **VideoEngine `onCompleted` rejects 0-byte output files** ([VideoEngine.kt:840-867](app/src/main/java/com/novacut/editor/engine/VideoEngine.kt#L840-L867)) — Transformer's COMPLETE callback was previously trusted unconditionally. On certain hardware-encoder edge cases (malformed input, codec init failure that the encoder didn't surface as an error), the file on disk could be 0 bytes despite the COMPLETE callback firing. Surfacing this as success let users share / save an unplayable artifact and trust it worked. Now treats `outputFile.length() <= 0` as ERROR with message "Export produced an empty file" and fires `onError`. + +### Diagnostics +- **Reverse-clip export warning** ([VideoEngine.kt:349-358](app/src/main/java/com/novacut/editor/engine/VideoEngine.kt#L349-L358)) — Media3 Transformer doesn't natively support reverse playback, so any `Clip.isReversed = true` exports forward today. Added a `Log.w` listing the count of reversed clips so logs / bug reports surface the limitation when the visible result doesn't match expectations. (Full reverse implementation would need FFmpeg-side re-encoding and is out of scope for this round.) + +### Audit findings verified as already-correct (false positives this round) +- **`VoiceoverRecorder.stopRecording` "silent failure"** — the catch block already cleans up the orphaned file and returns `null`; the EditorViewModel caller checks for null and toasts "Voiceover recording failed". +- **`VoiceoverRecorder` timestamp collision** — file naming uses `voiceover_${System.currentTimeMillis()}.m4a`; collision requires two recordings in the exact same millisecond on the same device, which the `@Synchronized` start/stop already serializes. +- **MediaPicker public `addClipToTrack` (delegate, 2-arg)** — `if (duration <= 0) { showToast; return }` guards against malformed media before the Clip is constructed; image clips return `DEFAULT_STILL_IMAGE_DURATION_MS = 3000L` from `getMediaDuration`. +- **Empty-timeline export crash** — the `IllegalStateException("No video clips to export")` is caught by the outer try at [VideoEngine.kt:386](app/src/main/java/com/novacut/editor/engine/VideoEngine.kt#L386) and surfaced as ERROR state with the exception message; not a crash. +- **`AppModule.provideProjectDao` missing `@Singleton`** — Room caches the DAO instance internally regardless of how many times Hilt provides it; no real perf impact. +- **`@Insert(onConflict = REPLACE)` race** — REPLACE is well-defined SQLite behavior; concurrent inserts of the same id are serialized by Room's writer thread. +- **Project delete cascade for proxy files** — proxies in `cacheDir/proxies/` are keyed by SHA-256 of source URI and shared across projects; correct cleanup needs reference counting (out of scope) and `cacheDir` is auto-managed by Android's storage manager. +- **Coil VideoFrameDecoder explicit registration** — Coil 2.x auto-discovers the `coil-video` artifact's decoder when the dep is on the classpath; no manual `ImageLoader.Builder` needed. + +### Verification +- `./gradlew compileDebugKotlin` passes. + +### Housekeeping +- `versionCode 97 → 98`, `versionName 3.36.0 → 3.37.0` +- `NovaCutApp.VERSION`, `app_version` string, README badge all synced. + +## v3.36.0 — Audit Phase 7: Batch Cancel, MediaStore Strict Update, GPU Resolution Floor, Segmenter Leak & Duplicate Atomicity + +### Batch export +- **Cancel now stops the queue** ([ExportDelegate.kt:330](app/src/main/java/com/novacut/editor/ui/editor/ExportDelegate.kt#L330)) — Previously, tapping the export-notification Cancel during a batch only cancelled the current item; the loop continued onto the next, ignoring the user's clear "stop" intent. The result-status case now distinguishes `CANCELLED` and breaks out of the loop. Failures still don't break (each batch item is independent and a long queue should tolerate per-item errors). +- **Per-item progress normalized to status** — `BatchExportItem.progress` is now explicitly set to `1f` on `COMPLETED` and `0f` on `FAILED` / `CANCELLED`. Without this, the queue UI would show "85% FAILED" on a job that errored partway through, and the COMPLETE row could stall at 0.99 because the progress collector got cancelled before observing the final tick. + +### Save-to-gallery integrity +- **MediaStore IS_PENDING update is now strict** ([ExportDelegate.kt:423](app/src/main/java/com/novacut/editor/ui/editor/ExportDelegate.kt#L423)) — `resolver.update(...)` returning 0 (no rows updated) means the file is still flagged pending and stays invisible to Gallery / Photos apps even though we showed the user a "Saved to gallery" success toast. Now treats `updated < 1` as an explicit failure so the catch block fires the `delete(contentUri)` cleanup path. + +### GPU resolution floor +- **`ShaderEffect.drawFrame` floors resolution at 1×1** ([ShaderEffect.kt:52](app/src/main/java/com/novacut/editor/engine/ShaderEffect.kt#L52)) — Several shader programs (sharpen, blur, vignette, scanlines, …) compute `1.0 / uResolution` and would produce per-pixel `Infinity` if Media3 ever calls `drawFrame` before `configure()` populated `width` / `height`. Coercing both to `≥ 1` at the uniform site protects every shader at once with no per-shader edits. + +### GPU resource leak +- **`SegmentationGlEffect.drawFrame` `segBitmap` leak hardened** ([SegmentationGlEffect.kt:87-100](app/src/main/java/com/novacut/editor/engine/segmentation/SegmentationGlEffect.kt#L87-L100)) — If MediaPipe's `engine.segment()` throws (bad-input frame, model tensor mismatch), the scaled bitmap leaked. Wrapped in try/finally so per-export-frame leaks under sustained errors can't exhaust GPU/native heap. The earlier v3.35 fix to `SegmentationEngine.segmentFrame` covered the picker preview path; this covers the hot export-render path. + +### Duplicate atomicity +- **`ProjectListViewModel.duplicateProject` rolls back on auto-save copy failure** ([ProjectListViewModel.kt:255-270](app/src/main/java/com/novacut/editor/ui/projects/ProjectListViewModel.kt#L255-L270)) — Previously did `insertProject` then `copyAutoSave` with no error handling. If the file copy failed (disk full, source missing), the Room row remained and opened as an empty project — the user would think "duplicate worked but lost my edits". Now wraps in try/catch and runs `deleteById(newId)` to roll back the orphaned row. + +### Audit findings verified as already-correct (false positives this round) +- `MainActivity` rotation re-import — manifest's `configChanges="orientation|screenSize|screenLayout|keyboardHidden"` prevents activity recreation on rotation; `onCreate` doesn't re-fire. +- `NovaCutApp.createNotificationChannels` API guard — `minSdk = 26` matches the API level where `NotificationChannel` was added; no guard needed. +- `SettingsRepository` corruption handling — DataStore's `CorruptionException` extends `IOException`, so the existing `if (error is IOException)` catch covers it. +- `EffectBuilder` EXPOSURE `Math.pow(2.0, value)` — `value.coerceIn(-2f, 2f)` directly above bounds the input; `pow` result ∈ [0.25, 4]. +- `SegmentationGlEffect` `glReadPixels` reading wrong FBO — agent misread the call order; readback happens BEFORE the saved FBO is restored at line 77. +- `EditorScreen` keyboard intercepting Space/Delete in TextFields — focused TextField consumes input keys before the parent's `onKeyEvent` fires; key auto-repeat for undo/seek is acceptable behavior. +- `ProjectListViewModel.renameProject` race with auto-save — `EditorViewModel`'s viewModelScope (and its auto-save coroutine) is cancelled when the user navigates back to the project list. + +### Verification +- `./gradlew compileDebugKotlin` passes. + +### Housekeeping +- `versionCode 96 → 97`, `versionName 3.35.0 → 3.36.0` (build.gradle.kts, NovaCutApp.VERSION, README badge, app_version string, CLAUDE.md, MEMORY.md). + +## v3.35.0 — Audit Phase 6: Keyframe Range Safety, Color Curve NaN Guard, Bitmap Leak & Caption Validation + +### Math correctness +- **`KeyframeEngine.getValueAt` clamps OPACITY and VOLUME to safe ranges** — Bezier curves with handles outside the unit square (and the `ELASTIC` / `BACK` / `SPRING` easings) can legitimately overshoot `[0, 1]`. For position / scale / rotation the overshoot is the desired effect (springy motion); for OPACITY and VOLUME it's a contract violation: opacity < 0 means "less than transparent", opacity > 1 brightens via `RgbMatrix`, and negative volume in `VolumeAudioProcessor` inverts phase. A new private `clampForProperty(value, property)` is now applied to every return path of `getValueAt`, so every consumer (preview, export, scopes) sees the same legal value. +- **`ColorCurves.evaluateCurve` guards against duplicate-x curve points** — If two adjacent points share the same x coordinate, `(input - p0.x) / (p1.x - p0.x)` divided by zero, producing NaN that propagated through the cubic-bezier into the color output (renders as black or wraps on GPU). Users could create this by dragging a curve handle exactly onto a neighbour, or via legacy auto-saves. Falls back to `p0.y` (visually-correct vertical step). + +### Resource leak +- **`SegmentationEngine.segmentFrame` bitmap leak hardened** — The original `frame` returned by `MediaMetadataRetriever.getFrameAtTime()` and the `scaled` copy were only recycled in the success path. If `Bitmap.createScaledBitmap` OOM'd or `segment(scaled)` threw partway through, both bitmaps leaked (~10 MB per call). Tracked via outer `var frame`/`var scaled` so the `finally` block guarantees recycling regardless of where the failure happens. Also corrected `targetMs * 1000` to `targetMs * 1000L` for explicit Long-multiplication intent. + +### Caption validation +- **`CaptionEditorPanel` Save buttons gated on non-blank text** — Both Save buttons (collapsed and expanded mode) now have `enabled = text.isNotBlank()`, and the saved value is `text.trim()`. Previously a user could save an all-whitespace caption that would render as nothing in the export but still consume timeline space. Trimming on save also normalizes captions like `" Hello "`. + +### Audit findings verified as already-correct (false positives this round) +- **MultiCamEngine.kt:91 `bestOffset.toLong() * 1000 / sampleRate`** — `Long * Int` is Long in Kotlin; no narrowing. +- **AiFeatures.kt:204 `sum / windowSamples`** — `windowSamples` is `(sampleRate / 10).coerceAtLeast(1)`, so divisor is always ≥ 1. +- **AiFeatures.kt:556 / 983 motion-estimation `bestDx / w`** — both call sites are guarded by `if (w < 8 || h < 8) return 0f to 0f` directly above. +- **AiFeatures.kt:2357 `coerceIn(1, halfSize - 1)`** — `halfSize` is at least 32 because of the `if (fftSize < 64) return` guard at line 2320. +- **AudioEngine.kt:194 `totalSamples` Int truncation** — would only matter for ≥ 6-hour audio mixes, where the FloatArray allocation (~7.6 GB) would OOM long before the Int overflowed; not a real concern in a video editor's mix path. +- **`RadialActionMenu` `LaunchedEffect(Unit) { visible = true }`** — composable is gated by `if (showRadialMenu)` in EditorScreen, so it's recreated each show; the `Unit` key is correct here. +- **EffectBuilder `buildVideoEffect` exhaustiveness** — every `EffectType` is covered; `SPEED` / `REVERSE` correctly map to `null` (not shaders). + +### Verification +- `./gradlew compileDebugKotlin` passes. + +### Housekeeping +- `versionCode 95 → 96`, `versionName 3.34.0 → 3.35.0` +- `NovaCutApp.VERSION`, `app_version` string, README badge all synced. + +## v3.34.0 — Audit Phase 5: CAS Safety, Backup Coverage, Performance Hot Path & Stale-String Cleanup + +### Concurrency safety +- **Hoisted UUIDs out of `_state.update {}` closures** — `MutableStateFlow.update` re-executes its lambda on each CAS-retry. Generating UUIDs inside the closure means a retry mints fresh IDs that don't match what any prior closure attempt observed. Fixed two real cases: + - **Paste-effects** (`EditorViewModel.kt:723`) — pre-mints `freshEffects` from `state.copiedEffects` once, then the closure just inserts them. + - **Freeze-frame** (`EditorViewModel.kt:3300`) — pre-mints `freezeClipId` and `secondHalfId` so the inserted freeze clip and the second-half clip have stable identities across retries. + - Practical impact is small (single-threaded UI, low CAS contention), but it's the kind of latent bug that surfaces only under load and is hard to diagnose later. + +### Backup coverage +- **`tts_output/` and `noise_reduced/` now in `backup_rules.xml` and `data_extraction_rules.xml`** — these directories were referenced by `file_paths.xml` and held real media that clips could reference, but were excluded from cloud backup and device transfer. After a restore, project clips that pointed at TTS-generated voiceovers or denoised audio would silently disappear from the timeline (post-v3.31 the load path skips dangling URIs cleanly, but the user still loses the clip). Both rule files now include them so projects round-trip across devices. + +### Performance hot path +- **`PreviewPanel` background brushes hoisted to `remember`** — Two `Brush.verticalGradient(listOf(...))` allocations inside `Column.background(...)` and the inner `Card`'s `Box.background(...)` were running on every recomposition. PreviewPanel recomposes on every playhead tick during playback (~30 Hz), so each frame was producing ~2 List + 2 Brush allocations purely for the GC. +- **`Timeline` per-clip selection brush hoisted to `remember(isSelected, isMultiSelected, clipColor)`** — the clip-rendering loop was allocating a fresh `Brush.horizontalGradient(listOf(...))` per visible clip per recomposition. With a busy timeline and Timeline recomposing on `scrollOffsetMs` updates, this was the dominant per-frame allocation. Now reused until selection or track-color state actually changes. + +### Stale-string cleanup +- **`@string/app_version` synced to `3.34.0`** — the resource was stuck on `v3.30.0` for several releases. It's not currently referenced from code (Settings already uses `NovaCutApp.VERSION`), but it's the kind of surface that appears in Play Store screenshots / accessibility scans when stale. + +### Audit findings verified as already-correct (false positives this round) +- `ExportConfig.videoBitrate` — computed property whose `when` exhaustively covers every `Resolution × ExportQuality` combination with positive bitrates; the `init { require(videoBitrate > 0) }` cannot trip. +- `Project.thumbnailUri` from `clips.firstOrNull()?.sourceUri?.toString()` — chained safe-calls, and `Clip.sourceUri` is rejected at deserialize time if empty (since v3.31). Returns `null` cleanly when there are no clips. +- `selectedClipIds` after `deleteMultiSelectedClips` — already reset to `emptySet()` at line 2730 in the same `_state.update`. +- `ExportService` Cancel-action path — `PendingIntent.getService()` only fires while the service is already in the foreground from the prior export start, so the Cancel branch returning before `startForeground()` is safe. +- Manifest `` for ACTION_SEND — `Intent.createChooser()` is exempt from Android 11+ package-visibility restrictions; no resolver calls in the codebase. +- Room `MIGRATION_4_5` — `CREATE INDEX IF NOT EXISTS` is idempotent; SQLite DDL is atomic. Sort order works regardless of index presence. + +### Verification +- `./gradlew compileDebugKotlin` passes. + +### Housekeeping +- `versionCode 94 → 95`, `versionName 3.33.0 → 3.34.0` (build.gradle.kts, NovaCutApp.VERSION, README badge, app_version string, CLAUDE.md, MEMORY.md). + +## v3.33.0 — Premium Polish: Design Tokens, Animated Snackbar, Onboarding Refresh & Export-State Hierarchy + +### Design system foundations +- **`ui/theme/Tokens.kt`** — New centralized design-token module exposing `Spacing`, `Radius`, `Elevation`, `Motion`, and `TouchTarget` scales. Replaces the ad-hoc `8.dp` / `tween(120)` / `RoundedCornerShape(14.dp)` literals scattered across panels. Future panels should reach for tokens rather than inventing one-off values, so the editor's rhythm stays coherent. + +### New components +- **`PremiumSnackbarHost` (`PremiumSnackbar.kt`)** — Animated, severity-aware Mocha-styled snackbar replacing the bare Material 3 `Snackbar` in the editor. Features: + - Slide-up + fade-in entrance / fade-out exit driven by the new `Motion` tokens + - Severity stripe (Info / Success / Warning / Error) with matching outlined icon — color is never the only signal (a11y) + - PanelHighest surface + hairline border, consistent with the rest of the editor's floating chrome + - Accent-tinted horizontal gradient that hints status without shouting + - `inferSeverity(message)` heuristic so the dozens of existing `showToast("…")` callsites get appropriate styling automatically; explicit `showToast(msg, ToastSeverity.Error)` is also available + - Adaptive duration: errors stay 4.5s, warnings 3.5s, info 2.8s +- **`PremiumHairlineDivider`** — Thin, slightly translucent divider for sectioning content inside `PremiumPanelCard`. Drops into existing card layouts with one line. + +### Onboarding refresh (`FirstRunTutorial.kt`) +- **Backdrop** — Replaced the flat 85% `Crust` scrim with a soft radial mauve→crust vignette. Reads as cinematic stage lighting instead of "the screen is dimmed". +- **Card** — Upgraded from a flat `Surface0` block to a bordered `PanelHighest` surface with a subtle vertical accent gradient and `12.dp` shadow elevation. Gives the tutorial card visible weight against the new vignette. +- **Step indicator** — Replaced equal-sized dots with an animated connected pill bar where the current step expands to 24dp (was: just got slightly bigger). Reads as "you are here" much faster. +- **Skip** — Bare `Text` upgraded to a translucent pill with a hairline border. Discoverable affordance instead of an ambiguous floating word. +- **Step transitions** — Now driven by the shared `Motion.DecelerateEasing` / `AccelerateEasing` tokens so it feels coherent with the rest of the app's motion language. +- **Typography** — Migrated from hardcoded `18.sp` / `13.sp` to `MaterialTheme.typography.headlineMedium` / `bodyMedium` for consistency with the rest of the editor. + +### ExportSheet — semantic primary-button styling +- **New `PrimaryStyle` enum** (`Filled`, `Destructive`, `Quiet`) routed to `ExportStateCard`. Each export state now picks a button treatment that matches its meaning: + - **Exporting → Cancel** — outlined Peach (was: filled Rosewater, indistinguishable from "Share completed export") + - **Complete → Share** — filled Rosewater (celebratory) + - **Cancelled → Done** — outlined neutral (informational, not celebratory) + - **Error → Retry** — filled Red (clear primary) +- **Animated progress bar** — `LinearProgressIndicator` is now driven through `animateFloatAsState` so it doesn't snap on each Transformer progress tick. Bar is also taller (10dp), pill-clipped, and uses a slightly translucent track for better contrast. +- **Percent label** — Bumped from `titleMedium` to `headlineMedium SemiBold` so the "47%" reads as the focal data point of the exporting card. +- **Icon halo** — Replaced single-circle treatment with a layered halo (outer translucent ring + inner filled disc) for visible depth without resorting to a hard shadow that would clash with the gradient surface. +- **Body text** — Now center-aligned, fixing prior visual imbalance with the centered headline above it. + +### Component refinement +- **`PremiumPanelCard`** — Trimmed the 3-stop accent gradient to a single soft fade. The previous middle stop produced a visible "fold" line halfway down every card; the new fade reads as restrained tinted glass. +- **`PremiumPanelCard`** — Standardized on `Radius.xl` / `Spacing.lg` / `Spacing.md` from the new token module instead of inline `24.dp` / `16.dp` / `12.dp`. +- **`PremiumEditorPanel` drag handle** — Slimmed from `44dp × 4dp` to `36dp × 3dp` and dimmed alpha from 0.8 to 0.55. Reads as a quiet gesture hint rather than a competing UI element. +- **EditorTopBar rename dialog** — Normalized unfocused border from `Mocha.Surface1` (too bright) to `Mocha.CardStroke`, matching the rest of the editor's input fields. + +### Snackbar message contrast +- Snackbar body uses primary `Mocha.Text` instead of `Mocha.Subtext1`. Status meaning is carried by the leading icon and accent stripe, leaving the message itself fully legible — important for short-duration toasts where users have ~3 seconds to read and decide. + +### Verification +- `./gradlew compileDebugKotlin` passes. + +### Housekeeping +- `versionCode 93 → 94`, `versionName 3.32.0 → 3.33.0` +- `NovaCutApp.VERSION` updated. + +## v3.32.0 — Audit Phase 4: Encoder Edges, DSP Parameter Hardening & Audio-Format Guards + +### Export / Encoder +- **GIF runaway-frame guard** — `gifFrameRate` is now coerced into `[1, 60]` and `frameIntervalMs` is floored at `1L`. Previously a stale or experimental >1000 fps value produced `1000 / fps == 0`, which made `frameCount = totalDurationMs / 0`, triggering an infinite frame loop, OOM, and an export that never returned. + +### Audio Engines +- **VolumeAudioProcessor channel guard** — `onConfigure` now also rejects `channelCount <= 0`, not just `sampleRate == 0`. A malformed audio track previously slipped through and divided by zero in the per-sample loop (`processedFrames / channelCount`), leaving an orphaned partial export file mid-render. +- **AudioEffectsEngine compressor parameter coercion** — `attack`, `release`, `knee`, `ratio`, and `sampleRate` are now floored at safe positive minima before being fed into `exp(-1f / (attackMs * sampleRate / 1000f))`. A zero `attack` previously produced `exp(-Infinity) = 0` (instant peak follow); a negative attack from corrupt state produced `exp(+Infinity) = NaN` and silently corrupted the audio buffer. + +### UX +- **TtsPanel input cap** — TTS script field is now bounded at 2,000 characters with an inline `len / 2000` indicator (Mocha.Peach when at limit). Prevents accidental paste-bombs from running unbounded synthesis jobs and OOM'ing the engine. + +### Audit Findings That Turned Out To Be Already-Correct +Spent careful verification against source rather than implementing every agent suggestion. False positives this round: GIF color-quantization operator precedence (Kotlin infix `shr`/`and` left-associativity already evaluates correctly), LoudnessEngine short-term loop bounds, BeatDetectionEngine BPM divide-by-zero (intervals already bounded to 200..2000ms), EffectsDelegate.updateEffect missing undo (debounced via `beginEffectAdjust()` by design), AiToolsDelegate stale clip refs (already re-validates inside coroutine and dispatches `currentClip`), MediaStore IS_PENDING handling in `saveExportedFile` (already deletes on exception), batch-export reset ordering (`resetExportState()` already runs before each item's `startExport`), and the four "missing contentDescription" reports (all decorative icons inside buttons / list items with adjacent text labels — adding cd would produce redundant TalkBack output). + +### Verification +- `./gradlew compileDebugKotlin` passes. + +### Housekeeping +- `versionCode 92 → 93`, `versionName 3.31.0 → 3.32.0` +- `NovaCutApp.VERSION` updated. + +## v3.31.0 — Audit Phase 3: Persistence Parity, Resource Leaks & Defensive Deserialization + +### Data Loss Fixes (CRITICAL) +- **ColorGrade.curves not serialized** — `ColorGrade.curves` (master/red/green/blue channel curves with per-point bezier handles) was completely missing from `ProjectAutoSave`. Users lost all RGB curve adjustments on project recovery / app restart. Now fully serialized via new `serializeColorCurves` / `deserializeColorCurves` helpers with bounds-coerced curve points. +- **ColorGrade.colorMatchRef not serialized** — Reference clip ID for "match color to reference" workflow was lost on recovery. Now persisted. + +### Defensive Deserialization +- **Clip fade bounds coerced** — `fadeInMs` and `fadeOutMs` are now coerced into `[0, clipDurationMs]` with `fadeIn + fadeOut <= clipDurationMs`. Previously raw values from corrupted auto-save could exceed clip duration and produce truncated/glitched fades on export. +- **Clip rejected for non-positive `sourceDurationMs`** — Previously zero-duration clips would silently load and break timeline math (division-by-zero risk). Now logged + skipped. +- **Safe URI parse** — `Clip.sourceUri`, `Clip.proxyUri`, and `ImageOverlay.sourceUri` now wrap `Uri.parse` in try/catch. Malformed URIs from a corrupt auto-save no longer take down the whole project recovery. +- **Format version bookkeeping** — `deserialize()` now reads the file's `version` field and logs a warning when an auto-save was written by a newer schema than the current build, instead of silently mis-parsing it. +- **Empty `sourceUri` clip drop logged** — Previously silent; now `Log.w` with clip ID for diagnostics. + +### Resource Leak Fixes +- **WhisperEngine encoder output leak** — `runEncoder` now closes both `OrtSession.Result` and `OnnxTensor` input in a `finally` block. Previously a `runDecoder` exception would orphan the encoder output OnnxTensor (~MB of native memory per chunk leaked on transcription failure). +- **WhisperEngine encoder result leak** — `runEncoder` previously closed `results` only on the success-cast path. Now uses unified try/finally, so the `OrtSession.Result` is closed on every exit including the `as? OnnxTensor` null path. +- **ColorMatchEngine bitmap leak** — `MediaMetadataRetriever.getFrameAtTime()` returns a bitmap that was never recycled (only the scaled copy made inside `analyzeBitmap` was). Now recycled in finally. Also corrected `timeMs * 1000` to `timeMs * 1000L` to make the long-multiplication intent explicit. + +### UI Hardening +- **PreviewPanel still-image `contentDescription`** — Now reads `R.string.cd_preview_still_image` instead of `null` (a11y). +- **PreviewPanel listener lifecycle** — `DisposableEffect` now captures the player reference up front and wraps `removeListener` in try/catch so a player released between attach and dispose can't crash the editor. +- **EditorScreen clip label picker keyed to selection** — `showClipLabelPicker` is now `remember(state.selectedClipId) { ... }`. Previously the picker stayed open after the user changed clip selection or deselected, painting the picker over the wrong (or no) clip. + +### Verification +- `./gradlew compileDebugKotlin` passes cleanly with the above changes. + +### Housekeeping +- `versionCode 91 → 92`, `versionName 3.30.0 → 3.31.0` +- `NovaCutApp.VERSION` updated to match for HTTP user-agent strings on model downloads + +## v3.30.0 — UI Polish & Panel Hardening + +### UI Improvements +- **Editor panels overhauled** — 25 panel composables refined: improved layouts, consistent Catppuccin Mocha theming, better accessibility content descriptions, and expanded string resources (259 new i18n entries). +- **Launcher icon reverted** — Restored halo + full letterform design. +- **KeyframeCurveEditor** — Richer curve visualization with grid lines, property-colored dots, and improved hit detection. +- **SpeedCurveEditor** — Enhanced canvas with reference line, higher-fidelity curve rendering (200 sample steps), and preset chip row. +- **VideoScopes** — Histogram, waveform, and vectorscope panels refined with better scaling and color accuracy. +- **TextTemplateGallery** — Expanded animated template library with category filtering and preview cards. +- **ToolPanel** — Smarter clip/project mode switching, sub-menu grid layout, and disabled-state feedback for clip-only actions. + +### Data Model +- **SpeedCurve.averageSpeed()** — New utility for sampling average speed across a curve with configurable sample count. + +### Housekeeping +- `versionCode 90 → 91`, `versionName 3.29.0 → 3.30.0` +- Room schema v5 export added + +## v3.29.0 — Audit Phase 2: Data Persistence, Thread Safety & Database Optimization + +### Data Persistence Fixes +- **24 missing `saveProject()` calls** — Added `saveProject()` to all discrete state-mutating functions in EditorViewModel that had `saveUndoState()` but never persisted: pasteClipEffects, addAdjustmentLayer, addCaption, removeCaption, applyCaptionStyle, applyBeatSync, applySpeedPreset, applyFillerRemoval, runAutoEdit, importEffects, addEffectKeyframe, analyzeAndReduceNoise, syncMultiCamClips, colorMatchToReference, applyTextTemplate, autoDuckAudio, addKeyframe, deleteKeyframe, setClipSpeedCurve, addMask, deleteMask, setClipBlendMode, unlinkAudioVideo, applyPipPreset. Users could undo changes that were never saved — on app restart, the undo stack was gone but the state never hit disk. + +### Thread Safety Fixes +- **SegmentationEngine race condition** — Added `@Synchronized` to `getOrCreateSegmenter()` to prevent concurrent threads from creating duplicate expensive `ImageSegmenter` instances. +- **applyPipPreset missing timeline rebuild** — Added `rebuildPlayerTimeline()` so PiP preset changes reflect in the player immediately. + +### Database & Storage Fixes +- **Room index on `updatedAt`** — Added `@Index("updatedAt")` to the Project entity and `MIGRATION_4_5` (database v4→v5) to create the index. Project list query (`ORDER BY updatedAt DESC`) was doing a full table scan. +- **TemplateManager import size limit** — `importTemplateFromUri()` now enforces a 10MB cap via chunked reading. Previously read the entire file into memory without limit. +- **Caption deserialization crash guard** — `ProjectAutoSave` now clamps `endTimeMs` when corrupt JSON has `endTimeMs < startTimeMs`, preventing `Caption.init` from throwing during project restore. + +### Housekeeping +- `versionCode 89 → 90`, `versionName 3.28.0 → 3.29.0` + +## v3.28.0 — Deep Engineering Audit: Correctness, Security & Resource Safety + +### Critical Fixes +- **StateFlowExt CAS loop** — Removed 100-retry limit that caused `IllegalStateException` under high contention; loop now runs unbounded with periodic `Thread.yield()`. +- **ProjectAutoSave `release()` deadlock** — Replaced `runBlocking` + mutex with scope cancellation to prevent ANR when Activity destroys. +- **ProjectAutoSave atomic writes** — Save uses temp file + rename + backup rollback pattern; interrupted saves no longer corrupt project files. +- **ProjectAutoSave `.bak` recovery** — `loadRecoveryData()` now restores from backup files left by interrupted saves. +- **AppModule destructive migration removed** — `fallbackToDestructiveMigrationOnDowngrade()` silently deleted all user projects on app downgrade; removed so downgrades now surface an error instead of silently deleting data. +- **VideoEngine export race condition** — Added `synchronized` block around export state check-and-set to prevent concurrent export starts. +- **AudioEngine MediaCodec resource leak** — Both `extractWaveform()` and `decodeToPCM()` now use `try-finally` with nullable decoder to guarantee `stop()`/`release()` on all paths. +- **WhisperEngine ONNX tensor lifecycle** — Decoder loop restructured: `OrtSession.Result` and `OnnxTensor` are now closed exactly once via `finally` block, preventing native memory leaks when `session.run()` succeeds but post-processing throws. + +### Security Fixes +- **Intent filter URI scheme hardening** — Removed `file://` scheme from AndroidManifest intent filter; only `content://` URIs are now accepted. +- **MainActivity intent validation** — Incoming `ACTION_VIEW` intents are validated: scheme must be `content://`, MIME type must resolve, invalid URIs are silently dropped. +- **SettingsRepository enum validation** — `updateDefaultCodec()` and `updateDefaultExportQuality()` now validate against known enum values, preventing garbage strings from being stored via corrupt settings or IPC. + +### Edge Case & Robustness Fixes +- **VolumeAudioProcessor NaN guard** — Added `isNaN()`/`isInfinite()` check on computed gain; handles edge case where `clipDurationMs <= fadeOutMs`. +- **SubtitleExporter invalid caption filter** — Captions with negative times or zero/negative duration are filtered before export instead of producing malformed subtitle files. +- **KeyframeEngine Newton-Raphson stability** — Increased near-zero slope threshold from `1e-7f` to `1e-5f` to prevent floating-point instability in bezier easing. +- **ExportDelegate batch queue snapshot** — Batch export queue is now copied with `.toList()` before iteration to prevent `ConcurrentModificationException` if queue is mutated during export. +- **VoiceoverRecorder thread safety** — Added `@Synchronized` to `startRecording()`, `stopRecording()`, and `release()` to prevent concurrent access from UI and lifecycle callbacks. +- **ProjectDatabase type converter logging** — Silent enum fallbacks in Room type converters now log warnings for diagnosability. + +### Housekeeping +- `versionCode 88 -> 89`, `versionName 3.27.0 -> 3.28.0` + +## v3.27.0 — Export & Archive Overhaul, UI Density Pass, File Safety + +### Engine / Core +- **Centralized file-name sanitization** — New `FileNaming.kt` utility replaces 6+ scattered inline regex calls with a single function that handles Windows reserved names, control chars, and extension preservation. All export/archive/template file paths now use it. +- **ProjectArchive rewrite** — Archives now include a `media_manifest.json` for reliable round-tripping of media URIs. Compound clips and image overlays are archived. Import rolls back created directories on failure and rewrites media URIs via manifest + fallback matching. +- **ProjectAutoSave.saveNow() is now suspend** — Removed `runBlocking` wrapper that could freeze the main thread during manual saves. +- **TemplateManager refactor** — DRY JSON serialization/deserialization via `templateToJson`/`parseTemplateJson`. Export by template ID instead of name. Duplicate name detection on import. Template stateJson is validated on load (corrupt templates are skipped instead of crashing). +- **Scoped-storage backup export** — Backup `.novacut` files are now written via MediaStore on API 29+ instead of direct filesystem access, fixing permission failures on Android 11+. +- **Backup import restores full state** — Beat markers, playhead position, and duration are now restored; panels are dismissed and the player timeline rebuilt after import. + +### Export +- **Named output files** — Exports now use the project name (or batch item name) instead of `NovaCut_`, with automatic `(2)`, `(3)` collision avoidance. +- **MediaScanner on pre-Q save** — Legacy save-to-gallery path now calls `MediaScannerConnection` so files appear in the gallery immediately. +- **Batch export summary** — Toast now reports passed/failed counts instead of a generic "complete" message. + +### UI / Layout +- **Compact top bar** — EditorTopBar adapts sizing and spacing on screens narrower than 430dp. Home icon replaced with a standard ArrowBack. +- **FlowRow everywhere** — Timeline info chips, export preset chips, batch export status pills, and export sheet sections now wrap instead of scrolling horizontally, preventing clipped or unreachable controls on narrow screens. +- **ExportSheet restructured** — Sections wrapped in descriptive cards. Summary hero, pills, and primary button label adapt to the active export mode (video, audio, stems, GIF, frame capture). +- **MediaPicker restructured** — Grouped into "Import from Library" and "Capture on Device" section cards with descriptions. +- **ProjectTemplateSheet** — Built-in and saved template sections have description text and an empty-state placeholder. +- **SettingsScreen** — Every section and picker now has a subtitle description for discoverability. +- **ProjectListScreen** — Added inline rename dialog for projects. +- **BatchExportPanel** — Failed/cancelled status pills; simplified item row (removable vs. in-progress only); `describeForQueue()` is now `@Composable` for string resources. + +### Strings +- 50+ new string resources for section descriptions, batch export states, media picker labels, and settings subtitles. + +### Build & Test +- JUnit 4 test dependency added; `FileNamingTest.kt` covers the new sanitization utility. +- `versionCode 87 -> 88`, `versionName 3.26.0 -> 3.27.0` + +## v3.26.0 — QA Audit: Crash, Leak & Persistence Fixes + +### Crash Fixes +- **WhisperEngine ONNX `results.first()`** — `runEncoder` and `runDecoder` called `.first()` on the ONNX Runtime results map, which throws `NoSuchElementException` if the model returns an empty result map. Replaced with `firstOrNull()?.value` and added explicit close of `results` + `idTensor` on the null path in `runDecoder` to avoid leaking tensors on the break path. + +### Resource Leaks +- **InpaintingEngine session + sessionOptions leak** — `OrtSession` was created before `Bitmap.createScaledBitmap`; if the bitmap allocation threw `OutOfMemoryError`, the session and `sessionOptions` were never closed. Restructured so all ONNX/bitmap/tensor resources are tracked in nullable locals and released in a single outer `finally` block, closing the session and session options on every exit path (including OOM during pre-processing). + +### Persistence / Data Loss Fixes +- **Beat markers silently lost on restart** — `detectBeats()` / manual `tapBeatMarker()` / `clearBeatMarkers()` wrote `beatMarkers` to state but `AutoSaveState` did not include the field at all, so beat analysis was dropped on every auto-save/recovery cycle. Added `beatMarkers: List` to `AutoSaveState`, wired it through all three construction sites in `EditorViewModel` (auto-save, snapshot, manual save), hydrated it in the recovery path, and added `saveProject()` calls after beat mutations. +- **`ColorGradingDelegate.hideColorGrading()` triggered auto-save on panel close** — The close handler called `saveProject()` even though closing a panel is UI-only state that never belongs in the project file. Removed the bogus call; wasted I/O eliminated and the auto-save indicator no longer flashes on every grading panel dismissal. + +### UX / State Fixes +- **SpeedCurveEditor log-slider polluted undo stack** — The fine-control log slider called `onConstantSpeedChanged` on every drag tick without invoking `beginSpeedChange()` / `endSpeedChange()`, so each drag created zero undo entries (never saved undo state at all), never rebuilt the player timeline, and never persisted via `saveProject()`. Added `onSpeedDragStarted` / `onSpeedDragEnded` callbacks to the composable, wired the slider with `onValueChangeFinished` + a `sliderDragActive` guard, bracketed preset chip taps with begin/end so each chip tap yields exactly one undoable action, and wired both to `viewModel::beginSpeedChange` / `viewModel::endSpeedChange` from `EditorScreen`. +- **TextEditorSheet retained stale state across edits** — All 21 `remember { mutableStateOf(existingOverlay?.xxx ?: default) }` blocks had no key, so if the sheet was ever re-composed with a different `existingOverlay` parameter the state would silently hold the previous overlay's values (text, font, colors, shadows, glow, rotation, position, animation). Keyed every remember block to `existingOverlay?.id ?: "__new__"` so state always tracks the overlay being edited. + +### Build +- `versionCode 86 → 87`, `versionName 3.25.1 → 3.26.0` +- Both debug and release builds pass cleanly (R8 minification + resource shrinking enabled) + +## v3.24.0 — Transitions & Smooth Playback + +### Transition System Overhaul +- **Per-clip effects during playback** — Transitions now preview live as playback crosses clip boundaries (previously only visible on selected clip) +- **Transition-out effects** — Outgoing clips now fade/wipe out to match the incoming clip's transition-in, creating seamless visual transitions +- **7 transition-out shader types** — Fade-out (black/white), wipe-out, slide-out, circle-close, zoom-out, and spin-out shaders activated at the end of outgoing clips +- **Export transition-out** — Transition-out effects now also apply during Transformer export, not just preview + +### Smooth Playback +- **Custom ExoPlayer buffer config** — Increased buffer sizes (5s min, 50s max, 1.5s playback, 3s rebuffer) for gapless multi-clip playback +- **Decoder fallback** — Enabled `DefaultRenderersFactory.setEnableDecoderFallback(true)` so playback recovers from codec failures instead of stopping +- **Reduced clip boundary stutter** — Larger pre-buffer window allows ExoPlayer to pre-decode the next clip before the current one ends + +### Timeline UI +- **Transition zone overlays** — Transition-in regions show a yellow gradient overlay with swap icon at the clip start; transition-out regions show a matching gradient at the outgoing clip's end +- **Duration-proportional indicators** — Transition zones scale with the actual transition duration instead of using a fixed 12dp square + +## v3.23.0 — Comprehensive Audit: 24 Bug Fixes + +### Crash Fixes +- **LRU cache overflow** — Thumbnail cache size capped to prevent `IllegalArgumentException` on 8 GB+ heap devices +- **ExportService leak** — Service now stops itself if export is already complete when `onStartCommand` fires +- **GIF double-recycle** — Removed duplicate `Bitmap.recycle()` in export error path that could crash on recycled bitmaps +- **Zero-duration clip guards** — `KeyframeCurveEditor` and `VolumeEnvelopeEditor` now return early when `clipDurationMs` is 0 + +### Correctness Fixes +- **Clip.getEffectiveSpeed** — Now uses raw trim range (`trimEndMs - trimStartMs`) instead of speed-adjusted `durationMs` for speed curve evaluation +- **EDL timecode rounding** — `msToTimecode` now rounds instead of truncating, fixing frame-inaccurate EDL exports +- **deleteMultiSelectedClips** — Now ripple-deletes (shifts subsequent clips backward) instead of leaving timeline gaps +- **applyFillerRemoval** — Now closes gaps after removing filler clips +- **splitClipAt** — First half now clears stale transition that belonged to the pre-split boundary +- **Audio filter stability** — Band-pass and notch filter frequency clamped to \[20 Hz, Nyquist) to prevent NaN coefficients +- **Waveform RMS** — Guards against empty sample buffer division by zero +- **Normalizer naming** — Renamed misleading `targetLufs` parameter to `targetPeakDb` (function implements peak normalization, not LUFS) + +### Data Persistence +- **Track volume/pan/solo** — Now save undo state before mutation (changes are undoable) +- **Audio effect params** — `updateTrackAudioEffectParam` now calls `saveProject()` (changes were lost on restart) +- **setClipLut** — Removed redundant double `saveProject()` call +- **Basic stabilization** — Now calls `rebuildPlayerTimeline()` and `saveProject()` (preview and persistence were broken) +- **Batch export** — Original export config now restored in `finally` block (was lost on cancellation) + +### Thread Safety +- **TtsEngine.preview()** — Now acquires mutex to prevent race with concurrent `synthesize()` calls +- **ProjectAutoSave.copyAutoSave** — Now acquires `saveMutex` to prevent reading partially-written files + +### UI/UX +- **Touch targets** — Enlarged critically undersized buttons: scopes toggle (28→40dp), text editor close (28→40dp), delete keyframe (24→36dp), search clear (20→36dp) +- **formatDate localization** — Now uses existing string resources instead of hardcoded English ("Just now", "Xm ago") +- **Hardcoded strings** — "TRIM MODE" hint and "Untitled" project name now use string resources + +## v3.22.0 — Data Safety, Export Correctness & Bug Fixes + +### ProjectAutoSave — 6 Missing Fields Fixed (Data Loss Prevention) +- **Mask.keyframes** — Animated mask keyframes now survive crash recovery +- **TextOverlay.textPath** — Text-on-path (curved, circular, wave) preserved on save +- **TextOverlay.templateId** — Template association no longer lost on recovery +- **TextOverlay.keyframes** — Animated text overlay keyframes now serialized +- **TimelineMarker.notes** — User notes on markers preserved across sessions +- **Clip.proxyUri + motionTrackingData** — Proxy state and motion tracking data persisted + +### Export Fixes +- **GIF speed calculation** — Frame extraction now accounts for clip speed (was ignoring it, producing wrong frames for non-1x clips) +- **MIME type detection** — `saveToGallery()` and `getShareIntent()` now use correct MIME types for GIF (`image/gif`) and WebM (`video/webm`) instead of hardcoded `video/mp4` +- **GIF saves to Pictures** — GIF exports now save to Pictures/NovaCut instead of Movies/NovaCut +- **Batch export config restore** — Original export config restored after batch export completes (was left as last batch item's config) +- **LZW code size** — Fixed off-by-one in GIF encoder code size increment + +### Bug Fixes +- **setTrackBlendMode** — Now rebuilds player timeline and saves project (was a no-op in preview) +- **pasteClipEffects** — Uses fresh state inside update lambda (was using stale captured reference) +- **deleteMultiSelectedClips** — Now cleans up waveform data for deleted clips (was leaking memory) +- **SpeedCurve NaN guard** — `getSpeedAt()` returns safe default when clipDurationMs is 0 +- **updateImageOverlay** — Now saves undo state (sticker edits were not undoable) +- **removeTextOverlay** — Clears `editingTextOverlayId` when removed overlay was being edited +- **addImageOverlay** — Duration clamped to timeline end (was exceeding total duration) +- **moveClipToTrack** — Validates target track type compatibility (was allowing video→audio moves) +- **seekTo** — Position clamped to valid range + +### Build Infrastructure +- **VMware HGFS build fix** — Added `doFirst` workaround in `build.gradle.kts` for AGP tasks that fail to delete output dirs containing `$` in filenames (Kotlin lambda class names) on VMware shared folders +- **Timeline lambda depth** — Extracted `volumeKeyframesSorted()` top-level helper to reduce deeply nested lambda class name length + +### Code Quality +- **Zero compiler warnings** — Migrated `EditedMediaItemSequence` to Builder pattern (`addItem`/`addItems`), replaced deprecated `Icons.Filled.RotateRight` with `Icons.AutoMirrored.Filled.RotateRight` + +### Error Logging +- Added `Log.w` to silent catch blocks: LutEngine (2), FrameCapture, VideoEngine, MultiCamEngine, MediaPicker (2) +- MediaPicker `takePersistableUriPermission` failures now logged (was silently losing URI permissions) + +## v3.21.0 — Trim Handles, Accessibility & Quality + +### Trim Handle Fix +- Clip edge trim handles now always visible on all clips (were hidden behind selection guard) +- Handles auto-select the clip on drag start — users can directly grab any clip edge to trim +- Unselected clips show subtler handle color (50% alpha) for visual hierarchy + +### Accessibility +- 27+ null contentDescriptions fixed across 16 UI files (37 new string resources) + +### Exception Logging +- 16 silent catch blocks now log warnings across 7 engine files + +### Stub Engine UX +- 4 unimplemented AI tool buttons (Frame Interpolation, Upscale, AI Background, Style Transfer) now show "Coming soon" toast + +## Unreleased + +### Brand Refresh +- Replaced the launcher icon with a new NovaCut adaptive mark built around a luminous `N`, a precision cut stroke, and a nova spark. +- Added Android monochrome themed icon support and a matching round adaptive icon resource. +- Added

Media3 Transformer requires a Looper, export runs withContext(Dispatchers.Main) -- **Multi-clip playback** via ExoPlayer setMediaItems() with ClippingConfiguration per clip -- **Player.Listener** syncs play/pause/end state; periodic coroutine syncs playhead at ~30fps. Tracked via `setPlayerListener()`/`removePlayerListener()` for proper lifecycle cleanup. -- **Auto-save** uses org.json serialization of full Track/Clip/Effect/Keyframe/TextOverlay model tree with safe deserialization (optString/optLong/safeValueOf — never crashes on missing or unknown values) -- **SavedStateHandle** for projectId in EditorViewModel, loaded from NavHost route arg -- **Panel mutual exclusion** — atomic `dismissedPanelState()` + show in single `_state.update` to prevent intermediate states. Voiceover panel included in dismissal. -- **Trim debounce** — `beginTrim()` saves undo once on drag start; `trimClip()` updates live without undo spam -- **Ripple delete** — clip deletion shifts subsequent clips back to close timeline gaps -- **Media type routing** — MediaPickerSheet passes media type string; audio routed to AUDIO track -- **rebuildPlayerTimeline()** — called after every clip mutation (add, delete, split, merge, trim, speed, reverse, undo, redo) to keep ExoPlayer in sync with visual timeline -- **VideoEngine is @Singleton** — ViewModel calls `removePlayerListener()` + `resetExportState()` in onCleared(), never `release()`. The engine outlives any individual ViewModel. -- **Thumbnail cache** — thread-safe LinkedHashMap with `cacheLock` synchronization and `removeEldestEntry` auto-eviction at 200 entries. `accessOrder=false` prevents ConcurrentModificationException. -- **AudioEngine PCM decode** — ShortArray chunks collected then concatenated via `System.arraycopy` to avoid boxing millions of Shorts through `MutableList` -- **Project thumbnails** — Stores first video clip's source URI in `Project.thumbnailUri`; Coil `VideoFrameDecoder` renders frame at display time (no file management needed) -- **Camera capture** — `ActivityResultContracts.CaptureVideo()` + FileProvider URI from cache dir. No CAMERA permission needed — delegated to system camera app via intent. -- **AI tools wiring** — `runAiTool(toolId)` dispatches to `AiFeatures` methods in viewModelScope. All 8 tools fully wired with else branch for unknown tool IDs. Scene detect auto-splits clips at boundaries (reverse-order). Auto captions detect speech via audio energy analysis and create TextOverlay entries. Smart crop uses saliency-weighted region analysis. Auto color analyzes frame histograms and applies brightness/contrast/saturation/temperature effects. Stabilize estimates motion vectors via block matching and applies counter-motion zoom + position keyframes. Denoise analyzes audio noise floor and adjusts volume/fade. Remove BG detects background color from edge pixels and applies chroma key. Track motion uses template matching across frames to generate position keyframes. -- **Audio fade persistence** — `fadeInMs`/`fadeOutMs` stored on Clip model (not local UI state). AudioPanel reads from clip data so values survive panel close/reopen. Serialized in ProjectAutoSave. -- **Duplicate clip** — copies clip with fresh UUIDs for clip + effects, inserts after original, shifts subsequent clips forward. Transition nulled on copy to avoid doubled transitions. -- **Merge clips** — merges selected clip with next adjacent clip from same source. Extends trimEndMs, combines effects, shifts subsequent clips back. Only works for same-source clips. -- **Copy/Paste effects** — `copiedEffects` in EditorState stores copied effect list. Paste creates fresh UUIDs to avoid ID collisions. -- **Freeze frame** — extracts JPEG via MediaMetadataRetriever at playhead, splits clip, inserts 2s still image clip between halves. -- **Share after export** — FileProvider URI + ACTION_SEND intent via `getShareIntent()`. Authority is `${applicationId}.fileprovider`. Requires `` in file_paths.xml. -- **Save to gallery** — MediaStore API with IS_PENDING pattern (API 29+), direct file copy for API 26-28. No WRITE_EXTERNAL_STORAGE needed on API 29+. -- **Project search/sort** — `ProjectListViewModel` combines allProjects with searchQuery + sortMode flows. SortMode enum: DATE_DESC, DATE_ASC, NAME_ASC, NAME_DESC, DURATION_DESC. -- **Project duplicate** — copies Room DB record + auto-save JSON file with fresh projectId and timestamp. -- **Social media crop presets** — CropPanel redesigned with platform labels (YouTube/TV, TikTok/Reels, Instagram Square/Portrait, Classic, Cinematic). Added RATIO_4_5 to AspectRatio enum. -- **PowerDirector-style layout** — EditorTopBar (Home/Undo/Redo/Delete/More/Export) + BottomToolArea with two-mode tab bar. Project mode: Edit/Audio/Text/Effects/AI/Aspect tabs. Clip mode: Back/Edit/Audio Tool/Speed/Transform/Effects/Transition/AI tabs. Tabs with sub-menus (Text, AI, clip-Edit) toggle SubMenuGrid overlays. Direct-action tabs dispatch via onAction string IDs to EditorScreen's when-block routing to ViewModel methods. Tab state resets on clip mode change via LaunchedEffect. -- **Voiceover recording** — VoiceoverRecorderEngine (MediaRecorder @Singleton) injected into EditorViewModel. Recording state tracked via StateFlow. Duration updated via polling coroutine (100ms). Recorded audio auto-added to AUDIO track as new clip. Cleanup in onCleared(). -- **Loop playback** — ExoPlayer REPEAT_MODE_ALL/OFF toggled via PreviewPanel loop button. State persisted in EditorState. -- **Transition duration control** — Slider in TransitionPicker (100-2000ms, 100ms steps). Updates Transition.durationMs on selected clip. -- **Font selector** — TextEditorSheet offers 6 font families (sans-serif, serif, monospace, cursive, condensed, medium). Stored in TextOverlay.fontFamily. -- **Photo Picker (API 33+)** — PickVisualMedia/PickMultipleVisualMedia for video, image, and multi-select on Android 13+. Falls back to OpenDocument on older APIs. -- **Export error handling** — `exportErrorMessage: String?` in EditorState, displayed in ExportSheet with retry button. Error state set from both Transformer.Listener.onError and catch block. `showExportSheet()` resets error state. -- **Auto-save error logging** — `Log.e(TAG, ...)` on auto-save failures instead of silent `catch (_: Exception) {}`. Still non-crashing but now debuggable via logcat. -- **Project delete cleanup** — `ProjectListViewModel.deleteProject()` now calls `autoSave.clearRecoveryData()` to remove orphaned auto-save JSON files. -- **Waveform fade envelope** — AudioPanel Canvas draws fade in/out envelope overlay (stroke line + dimmed fill) on top of waveform visualization. Reads `fadeInMs`/`fadeOutMs` from clip model. -- **Trim mode indicator** — Timeline shows "TRIM MODE — Drag clip edges to adjust" banner (Mocha.Peach) when `currentTool == EditorTool.TRIM` and a clip is selected. -- **Timeline keyframe dots** — Clips with keyframes display small pink dots along the bottom edge at each keyframe's time position. -- **Timeline effects badge** — Clips with effects show "FX{n}" badge in top-right corner (Mocha.Mauve background). -- **AI disabled tool feedback** — `onDisabledToolTapped` callback on AiToolsPanel. Tapping a tool that requires clip selection shows "Select a clip to use {toolName}" toast. Card always clickable (removed Material3 `enabled=false` which blocked taps). - -## Features Wired & Working -- Project gallery (create, open, delete, swipe-to-delete with confirm) -- Navigation:

Export 14 GLSL shader effects (vignette, sharpen, film grain, gaussian/radial/motion blur, tilt shift, mosaic, fisheye, glitch, pixelate, wave, chromatic aberration, chroma key) -- Export 25 transition types via GLSL shaders (dissolve, fade black/white, wipe 4-way, slide 2-way, zoom in/out, spin, flip, cube, ripple, pixelate, directional warp, wind, morph, glitch, circle open, cross zoom, dreamy, heart, swirl) -- Export respects track mute/visible (hidden video tracks excluded, muted tracks silenced, muted audio tracks omitted) -- Export applies frame rate from config via FrameDropEffect (24/30/60fps frame dropping) -- Export applies audio bitrate from config via AudioEncoderSettings (256kbps default) -- Export text overlay fontFamily (TypefaceSpan), backgroundColor (BackgroundColorSpan), alignment (AlignmentSpan) -- Export cancel button in ExportSheet (TextButton in EXPORTING state, wires to VideoEngine.cancelExport) -- Android back button handling (BackHandler: dismiss panel > clear tool > deselect clip) -- Success toasts for split/duplicate/merge operations -- Auto-pause playback when opening any panel (pauseIfPlaying in all show* methods) -- Paste effects dim hint (SubMenuGrid disabledIds with alpha 0.35f when no copied effects) -- Clip filename labels on timeline clips (8sp, semi-transparent, hidden on narrow clips) -- Track mute/visible/lock toggle icons in timeline track headers (11dp color-coded icons) -- Effect enable/disable toggle (eye icon in EffectAdjustmentPanel header, disabled effects skipped in export) -- Project name display in EditorTopBar center (tap to rename via AlertDialog) -- Overflow menu: Add Media, Add Track (Video/Audio/Overlay/Text submenu), Rename Project -- Add Track from overflow menu (creates new track of selected type) - -## Gotchas -- Media3 Transformer effects use `@UnstableApi` annotation - suppress with `@OptIn` -- Thumbnail extraction via `MediaMetadataRetriever` is slow - use caching aggressively -- `largeHeap=true` in manifest is required for video editing workloads -- Room `fallbackToDestructiveMigration()` - no `dropAllTables` parameter in Room 2.6.1 -- Room DB stores project metadata only - track/clip state serialized separately via ProjectAutoSave -- FFmpeg not yet integrated - using pure Media3 pipeline -- VideoEngine is @Singleton - don't call `release()` from ViewModel onCleared (use `removePlayerListener()` + `resetExportState()`) -- `local.properties` not in git - must be created with sdk.dir path -- RgbMatrix color matrices are row-major 4x4: `[R_out = row0 dot [R,G,B,A]]`. Alpha channel (=1) serves as offset for translation effects (brightness, invert). -- OES shader extension for GLES 3.0 is `GL_OES_EGL_image_external_essl3` (not `GL_OES_EGL_image_external`) -- Room TypeConverters must handle unknown enum values gracefully (try/catch around valueOf) -- `startForegroundService()` required on API 26+ (minSdk), with SDK version check for compatibility -- Auto-save deserialization uses `opt*` methods throughout to survive missing/corrupt fields -- Room DB v1→v2→v3 migration handled by `fallbackToDestructiveMigration()` — drops all data on schema change. Acceptable for dev; needs proper migration before release with user data. -- FileProvider requires `res/xml/file_paths.xml` with `` entry matching the directory used for camera temp files -- FileProvider authority is `${applicationId}.fileprovider` — must match in manifest, file_paths.xml, and all code references -- AI scene detection splits clips in reverse-order (sortedByDescending) to prevent timeline position shifts from invalidating subsequent split points -- AI auto color replaces existing effects of same type (brightness/contrast/saturation/temperature) to prevent stacking -- AI stabilize applies zoom + position keyframes — both stored on Clip model (scaleX/Y + keyframes list) -- AI denoise uses volume boost + fade as proxy for noise gating (real spectral subtraction would require custom audio codec pipeline) -- AI remove BG uses chroma key effect — works well for green/blue screen, moderate for general backgrounds -- AI motion tracking generates POSITION_X/POSITION_Y keyframes, merges with existing keyframes (replaces position keyframes, preserves others) -- TRIM and SPLIT tools must call `dismissAllPanels()` — they bypass the boolean-panel pattern since they don't have their own panels -- Speed panel visibility driven by `currentTool == EditorTool.SPEED` (not a boolean flag like other panels), so it self-dismisses on tool change -- BottomToolArea manages `activeTabId` internally — sub-menu visibility is derived from activeTabId + isClipMode, not stored in ViewModel. LaunchedEffect resets activeTabId when isClipMode changes. -- Merge clips only works with adjacent clips from the same source URI (extends trim range) -- VoiceoverRecorderEngine is @Singleton but `release()` is safe to call from onCleared() (unlike VideoEngine) since each recording session is independent -- Photo Picker `takePersistableUriPermission` may throw SecurityException for picker-selected URIs — caught silently since picker grants temporary access -- ExportSheet error state includes `exportErrorMessage` — reset in `showExportSheet()` to prevent stale errors on reopen -- AiToolsPanel disabled tools use always-clickable Card (not Material3 `enabled=false`) to allow tap feedback dispatch -- AudioPanel fade envelope `drawFadeEnvelope()` uses Compose Path — needs `import androidx.compose.ui.graphics.Path` (already imported via wildcard) -- **NovaCutApp.VERSION** — must match build.gradle.kts versionName. Used for notification channel or display; was stale at "v0.3.0" until v0.12.0 fix. -- **VideoEngine export logging** — `Log.e(TAG, ...)` in both Transformer.Listener.onError and catch block. `TAG = "VideoEngine"` for logcat filtering. -- **Effect parameter bounds** — `coerceIn()` on all effect params in `buildVideoEffect()`: brightness ±1, contrast 0-2, saturation 0-3, temperature ±5. Prevents garbled output from unbounded values. -- **Text overlay undo** — `updateTextOverlay()` now calls `saveUndoState("Edit text")`. `addTextOverlay` and `removeTextOverlay` already had undo. -- **Timeline auto-scroll** — During playback, if playhead crosses 80% of visible timeline width, scrollOffsetMs jumps to place playhead at 25% position. Uses `@Volatile var timelineWidthPx` in ViewModel (outside EditorState to avoid recomposition). Timeline reports width via `onTimelineWidthChanged` callback. -- **Export progress clamped** — `coerceIn(0, 99)` while exporting to avoid premature "100%" display (COMPLETE state shows final confirmation instead). -- **Export bitrate descriptions** — Output details card shows human-readable quality hint ("Studio quality", "Great for YouTube/social", "Good for sharing", "Compact file size") alongside Mbps number. -- **Keyframe deduplication** — `KeyframeEngine.getValueAt()` applies `distinctBy { it.timeOffsetMs }` after sorting to prevent division-by-zero when duplicate keyframes exist at same timestamp. -- **SubMenuGrid scroll** — Grid now uses `verticalScroll(rememberScrollState())` with `heightIn(max = 200.dp)` to handle overflow on small screens. -- **Centralized effect defaults** — `EffectType.defaultParams(type)` companion method in `Project.kt` replaces duplicate default maps in `EditorScreen.kt` and `ToolPanel.kt`. Single source of truth for all 40+ effect default parameters. -- **AI tool cancellation** — `runAiTool()` stores `Job` reference in `aiJob` field. `cancelAiTool()` cancels the coroutine. `CancellationException` re-thrown after toast. AiToolsPanel processing indicator shows "Cancel" button. -- **Accessibility content descriptions** — Added to ExportSheet (Share, Save to gallery, Retry, Export video), AudioPanel (Record voiceover), EditorScreen (Add media) icons. -- **Effect adjustment undo debounce** — `EffectSlider` now has `onDragStarted` callback (like SpeedSlider). `beginEffectAdjust()` saves undo state once when slider drag begins, preventing undo spam during continuous adjustment. Threaded through `EffectAdjustmentPanel.onEffectDragStarted` → `EditorScreen` → `EditorViewModel.beginEffectAdjust()`. -- **Split validation before undo** — `splitClipAtPlayhead()` now validates that the playhead is within the selected clip's bounds BEFORE saving undo state. Prevents polluting undo stack with no-op split attempts. -- **Timeline trim guard** — Both left and right trim handle drag handlers now guard against `currentPixelsPerMs < 0.001f` to prevent division-by-zero at extreme zoom levels. -- **Text editor blank guard** — TextEditorSheet Save button disabled when text is blank. Button color dims to indicate disabled state. -- **Smart duplicate naming** — `ProjectListViewModel.duplicateProject()` strips existing `(Copy N)` suffix and increments: "Project (Copy)" → "Project (Copy 2)" → "Project (Copy 3)" to avoid cascading "(Copy) (Copy)" names. -- **Action dispatch logging** — EditorScreen `onAction` when-block has `else` branch with `Log.w("EditorScreen", "Unknown action: $actionId")` for debugging unhandled action IDs. -- **Auto-save failure tracking** — `ProjectAutoSave` tracks consecutive failures. After 3+ in a row, logs `Log.w` warning. Counter resets on success or `startAutoSave()`. Stale `.tmp` files cleaned up on `loadRecoveryData()`. `saveState()` ensures temp file cleanup on write failure. `copyAutoSave()` and `loadRecoveryData()` now log errors instead of silently swallowing. -- **Merge validation before undo** — `mergeWithNextClip()` now validates next-clip existence and same-source URI BEFORE saving undo state. Prevents undo stack pollution from failed merge attempts. Toasts shown for specific failure reasons. -- **Transition duration undo debounce** — `beginTransitionDurationChange()` saves undo state once when slider drag starts. `TransitionPicker` slider has `onDurationDragStarted` callback with isDragging tracking (same pattern as EffectSlider and SpeedSlider). -- **AudioEngine error logging** — `extractWaveform()` catch block now logs `Log.e(TAG, ...)` with exception details instead of silently returning empty array. TAG = "AudioEngine". -- **Fade envelope bounds guard** — `drawFadeEnvelope()` now returns early for `durationMs <= 10` (previously `<= 0`), preventing extreme path coordinates from tiny clip durations. -- **Atomic copyAutoSave** — `copyAutoSave()` now uses the same temp-file + rename pattern as `saveState()` to prevent partial writes on failure. -- **AI tool null safety** — `runAiTool()` now requires clip for ALL tools (removed `auto_color` exception). All `clip!!` replaced with safe `clip` val that's guaranteed non-null after the unified null guard. Prevents NPE when AI tool dispatched without clip selection. -- **Trim bounds coercion** — `trimClip()` now coerces `trimStartMs` to `0..sourceDurationMs-100` and `trimEndMs` to `trimStartMs+100..sourceDurationMs`. Prevents trim ranges exceeding source file bounds. -- **Split minimum duration** — `splitClipAtPlayhead()` validates both resulting halves are >= 100ms in source time before proceeding. Shows "Clip too short to split here" toast on failure. -- **Delete/duplicate undo pre-validation** — Both `deleteSelectedClip()` and `duplicateSelectedClip()` now verify clip existence in tracks before calling `saveUndoState()`. Same pattern as merge/split validation. -- **Deserialization failure logging** — All `mapNotNull` catch blocks in `ProjectAutoSave` deserialization now log `Log.w(TAG, ...)` with index and exception. Covers clips, effects, keyframes, and text overlays. -- **Fade undo debounce** — `beginFadeAdjust()` saves undo state once on drag start for fade in/out sliders. Uses same `onDragStarted` callback pattern as volume/speed/effect sliders. Wired through `AudioPanel.onFadeDragStarted` → `EditorViewModel.beginFadeAdjust()`. -- **Fade bounds coercion** — `setClipFadeIn()` constrains fadeInMs to `0..(durationMs - fadeOutMs)`. `setClipFadeOut()` constrains fadeOutMs to `0..(durationMs - fadeInMs)`. Prevents fade overlap exceeding clip duration. -- **Share intent toast feedback** — `getShareIntent()` now shows toast before returning null: "No exported video to share" for missing path, "Export file no longer available" for deleted file. -- **Export progress reset on error** — Both error paths in VideoEngine (Transformer.Listener.onError and outer catch) now reset `_exportProgress.value = 0f` alongside setting ERROR state. Ensures retry shows fresh progress bar. -- **Export aspect ratio from project** — `ExportConfig` now has `aspectRatio` field. `startExport()` copies project's aspect ratio into config. `VideoEngine.export()` uses `config.aspectRatio` instead of hardcoded `RATIO_16_9`. All 7 aspect ratios (16:9, 9:16, 1:1, 4:3, 3:4, 4:5, 21:9) correctly applied to export output dimensions. -- **Right trim handle upper bound** — Timeline right trim handle now coerces to `clip.sourceDurationMs` on the UI side, preventing visual glitch where clip appears longer than source during drag. -- **Thumbnail cache zoom eviction** — `LaunchedEffect` evicts thumbnail entries for non-current zoom levels before loading new ones. Prevents unbounded Bitmap memory growth across zoom sessions. -- **Safe bitmap cache clearing** — `clearThumbnailCache()` no longer calls `recycle()` on cached Bitmaps since they may still be referenced by Compose Image composables. GC handles reclamation after references are dropped. -- **ExportService setup-phase safety** — `startExport()` wraps `videoEngine.export()` in try/catch to stop the foreground service even if export setup throws before Transformer listener is registered. -- **Deserialization safe getters** — `deserializeClip()` now uses `optString`/`optLong` for all fields (id, sourceUri, sourceDurationMs, timelineStartMs, trimStartMs, trimEndMs). Returns null for missing sourceUri. Transition uses `optJSONObject` instead of throwing `getJSONObject`. Consistent with `deserializeEffect`/`deserializeKeyframe` patterns. -- **Dead metadata key removed** — `getVideoFrameRate()` no longer calls `extractMetadata(24)` (undocumented constant, always returned null). Falls back directly to 30fps default. -- **Multi-clip seek** — `VideoEngine.seekTo()` now computes which media item index the target position falls into and calls `player.seekTo(index, positionWithinItem)`. `clipDurationsMs` list stored on `prepareTimeline()`. `getAbsolutePositionMs()` returns sum of preceding clip durations + `currentPosition` for accurate playhead sync. -- **Paste effects dedup** — `pasteEffects()` now filters out effect types already present on the target clip before pasting. Shows "Effects already present on clip" if all pasted types are duplicates. -- **Merge contiguous validation** — `mergeWithNextClip()` now validates `clip.trimEndMs == nextClip.trimStartMs` to prevent including trimmed-out footage when merging non-adjacent trim ranges. -- **Voiceover permanent storage** — Voiceover recordings now saved to `filesDir/voiceovers/` instead of `cacheDir`. Freeze frames saved to `filesDir/freeze_frames/`. Both survive cache cleanup and device reboot. -- **Project-mode AI tab removed** — AI tools only available in clip mode (when a clip is selected). Removed dead `projectAiSubMenu` and its tab entry from `projectTabs`. -- **Snackbar z-ordering** — Toast Snackbar now uses `zIndex(10f)` and `bottom = 120.dp` padding to render above bottom sheets and tool panels. -- **ExportService @AndroidEntryPoint** — Service now uses Hilt DI to inject VideoEngine @Singleton. Collects `exportProgress`/`exportState` StateFlows via `combine()` to update notification in real-time. Self-manages lifecycle (stopSelf on COMPLETE/ERROR/CANCELLED). ViewModel no longer calls `stopService()`. -- **Export cancellation** — `VideoEngine.cancelExport()` sets `CANCELLED` state and calls `transformer.cancel()`. `activeTransformer` stored as `@Volatile` field, cleared after export completes or fails. ExportService `ACTION_CANCEL` now calls `videoEngine.cancelExport()` instead of just `stopSelf()`. CANCELLED state added to `ExportState` enum. -- **VolumeAudioProcessor** — Custom `BaseAudioProcessor` that applies volume scaling and fade in/out envelope to 16-bit PCM audio during export. Tracks sample position to compute time offset for fade calculations. Only created when `volume != 1.0f` or `fadeInMs > 0` or `fadeOutMs > 0`. -- **Export audio effects wired** — `Effects(audioProcessors, videoEffects)` now passes `VolumeAudioProcessor` list instead of `emptyList()` for audio. Each clip gets its own processor with its specific volume/fade settings. -- **VolumeAudioProcessor encoding validation** — `onConfigure()` validates `C.ENCODING_PCM_16BIT`. Non-16-bit audio formats rejected with `UnhandledAudioFormatException` to prevent garbled output. -- **ExportSheet CANCELLED state** — Dedicated UI state for cancelled exports: `Icons.Default.Cancel` in Mocha.Peach + "Export Cancelled" text + Done button. Prevents CANCELLED falling through to idle/config view. -- **Text overlay editing flow** — `editingTextOverlayId: String?` in EditorState. `editTextOverlay(id)` sets the ID and shows TextEditorSheet. EditorScreen resolves overlay by ID and passes to sheet. onSave calls `updateTextOverlay` (edit) vs `addTextOverlay` (new). -- **Text overlay list UI** — `TextOverlayList` composable in ToolPanel. Shows when text tab active and overlays exist. Each item: colored icon, text preview (1 line), time range, edit + delete buttons. Scrollable with 150dp max height. -- **Camera temp cleanup** — `LaunchedEffect(Unit)` in MediaPickerSheet deletes files in `cacheDir/camera/` older than 1 hour. Safe because camera launcher completes before user opens picker again. -- **dismissedPanelState includes editingTextOverlayId** — Reset to null alongside all panel booleans to prevent stale overlay editing state. -- **Export color effects expanded** — `buildVideoEffect()` now handles 20+ effect types via RgbMatrix: TINT, EXPOSURE, GAMMA, HIGHLIGHTS, SHADOWS, VIBRANCE, POSTERIZE, COOL_TONE, WARM_TONE, CYBERPUNK, NOIR, VINTAGE, MIRROR (via ScaleAndRotateTransformation). Effects requiring custom GL shaders (blur, distortion, vignette, etc.) still return null. -- **Export clip transforms** — Clip rotation, scaleX, scaleY applied via `ScaleAndRotateTransformation.Builder()` in export. Position X/Y not yet supported (requires MatrixTransformation with translation matrix). Static opacity applied via RgbMatrix when no keyframe opacity overrides exist. -- **Export audio track** — Audio track clips (background music, voiceovers) exported as second `EditedMediaItemSequence` with `setRemoveVideo(true)`. Each audio clip gets its own `VolumeAudioProcessor`. `Composition.Builder` uses `setTransmuxAudio(true)` when no audio track to avoid re-encoding video audio. -- **Export text overlays** — `ExportTextOverlay` class extends `androidx.media3.effect.TextOverlay` (not to be confused with model `TextOverlay`). Renders styled SpannableString with ForegroundColorSpan, AbsoluteSizeSpan, StyleSpan. Time-gated: returns empty string + alpha 0 outside `relStartMs..relEndMs`. Position converted from 0..1 model space to -1..1 anchor space (Y inverted). Added via `OverlayEffect(ImmutableList.copyOf(typed))` after effects but before Presentation. -- **TextOverlay name collision** — `com.novacut.editor.model.TextOverlay` and `androidx.media3.effect.TextOverlay` both imported via wildcards. Export function parameter uses fully qualified `com.novacut.editor.model.TextOverlay`. `ExportTextOverlay` extends fully qualified `androidx.media3.effect.TextOverlay()`. -- **EditedMediaItemSequence.Builder** — Migrated from deprecated `EditedMediaItemSequence(list)` constructor to `EditedMediaItemSequence.Builder(list).build()` pattern (Media3 1.5.x). -- **Portrait resolution fix** — `Resolution.forAspect()` now branches on aspect ratio >= 1 vs < 1. For portrait aspects (9:16, 3:4, 4:5), height (shorter dimension) becomes width and the taller dimension is derived. FHD_1080P + 9:16 now correctly produces 1080x1920 instead of 608x1080. -- **Undo/redo recalculates totalDurationMs** — Both `undo()` and `redo()` now wrap restored state through `recalculateDuration()` to keep timeline duration accurate after state restoration. -- **Auto_captions in clip AI menu** — Moved from project-mode textSubMenu (unreachable, required clip) to clip-mode clipAiSubMenu. `auto_color` also added to clipAiSubMenu (was wired in EditorScreen but missing from menu). -- **Keyframe-animated transforms in export** — `MatrixTransformation` replaces static `ScaleAndRotateTransformation` when keyframes exist for SCALE_X/SCALE_Y/ROTATION/POSITION_X/POSITION_Y. Uses `android.graphics.Matrix` with `postScale`/`postRotate`/`postTranslate` (scale → rotate → translate order). Falls back to static keyframe values when no keyframe for a property. -- **Static clip position in export** — `clip.positionX`/`positionY` now applied via `MatrixTransformation` (previously only rotation/scale were exported). Y axis inverted (`-py`) to match GL coordinate system. -- **Keyframe volume in export** — `VolumeAudioProcessor` accepts optional `keyframes` list. When present, evaluates `KeyframeEngine.getValueAt(VOLUME)` per audio sample instead of using static `volume`. Fade envelopes still applied on top of keyframe volume. - -- **Dead ShaderEffects.kt removed** — 509 lines of unused GLSL shader code deleted. All effects use Media3 RgbMatrix/GlEffect in VideoEngine, not custom shader compilation. -- **Waveform extraction on project recovery** — Auto-save restore now launches `extractWaveform()` for all recovered clips. Previously only new clips got waveforms; recovered projects showed placeholders. -- **Text overlay animation export** — `ExportTextOverlay.getOverlaySettings()` now computes per-frame alpha, position offset, scale, and rotation based on `animationIn`/`animationOut` fields. 500ms animation duration. Typewriter handled in `getText()` via progressive character reveal. Bounce uses multi-segment ease-out. Animations compose: in + out can be different types. -- **clip.isReversed not exported** — Known limitation. Media3 Transformer has no reverse playback support. Would require FFmpeg or custom frame-reversal pipeline. `isReversed` works in preview but not in export. -- **Back action dismisses panels** — "back" action in BottomToolArea now calls `dismissAllPanels()` before `selectClip(null)`. Prevents NPE from open panels referencing deselected clip. -- **Export progress poll timeout** — Progress polling loop capped at 2400 iterations (10 minutes at 250ms intervals). On timeout, calls `transformer.cancel()`, sets ERROR state, and reports "Export timed out". Prevents infinite loop if Transformer hangs. - -- **Release signing CI fallback** — `build.gradle.kts` release signingConfig now falls back to debug signing when neither `keystore.properties` nor bundled `novacut-release.jks` exist (CI environment). Previously failed with "Keystore file not found" on GitHub Actions. -- **Version string in strings.xml** — `app_version` resource must be updated alongside NovaCutApp.VERSION and build.gradle.kts versionName. Was stuck at v0.1.0 for 30 releases. -- **Backup rules include freeze_frames and voiceovers** — Both directories live in `filesDir` and are now included in `backup_rules.xml` (legacy) and `data_extraction_rules.xml` (Android 12+). Without this, user recordings and freeze frames would be lost on device transfer. -- **ProGuard keeps Room Converters** — Explicit `-keep class com.novacut.editor.engine.db.Converters { *; }` rule added. Without it, R8 could strip the class since it's only referenced by annotation, causing AspectRatio/Resolution TypeConverter crashes at runtime. -- **VoiceoverRecorder double-start cleanup** — `startRecording()` now stops and releases any existing MediaRecorder before creating a new one. Prevents resource leak (mic hardware lock, memory) if called while already recording. -- **estimateRegionMotion divide-by-zero guard** — `estimateRegionMotion()` in AiFeatures.kt now returns `0f to 0f` when bitmap width or height < 8, matching the guard in `estimateMotion()`. Prevents ArithmeticException on malformed video frames during motion tracking. -- **createProject race condition fixed** — `createProject()` now accepts an `onCreated` callback that fires after the Room insert completes, instead of returning the ID synchronously before the async insert. Prevents navigation to a non-existent project. -- **Timeline waveform empty array guard** — `drawWaveform()` now returns early if `samples.isEmpty()` to prevent `coerceIn(0, -1)` IllegalArgumentException when AudioEngine returns empty FloatArray on decode failure. -- **Gallery save null URI handling** — `saveToGallery()` now shows error toast and returns early when `ContentResolver.insert()` returns null (e.g., scoped storage rejection on API 30+). Previously silently fell through to "Saved to gallery" success toast. -- **Auto-scroll pixelsPerMs guard** — Playhead sync loop guards `pixelsPerMs >= 0.001f` before computing `visibleMs` to prevent division-by-zero at very low zoom levels. -- **Text overlay time validation** — `addTextOverlay()` and `updateTextOverlay()` reject overlays where `startTimeMs >= endTimeMs` with toast feedback. -- **Transition duration bounds on deserialization** — `deserializeTransition()` clamps `durationMs` to 100-2000ms range via `coerceIn()` to match UI slider bounds. -- **Export state snapshot** — `startExport()` captures `tracks`, `textOverlays`, and `config` before launching coroutine, preventing race conditions where state changes between validation and export call. -- **Timeline time labels** — `drawTimeRuler()` now draws time labels at major tick marks using `TextMeasurer`. Format: "0s", "5s", "1:00", etc. Ruler height increased from 24dp to 28dp. -- **Timeline playhead drag** — Ruler Canvas has tap + drag gesture handlers (`detectTapGestures` + `detectDragGestures`) for positioning playhead by tapping/dragging on the ruler. -- **Undo/redo stale state fix** — `undo()` and `redo()` now validate `selectedClipId` exists in restored tracks, call `dismissedPanelState()`, and set `currentTool = EditorTool.NONE`. -- **Smart crop applies transform** — AI smart crop now uses `setClipTransform()` to apply positionX/positionY instead of just showing a toast. -- **Fade slider dynamic max** — AudioPanel fade sliders now use `clip.durationMs` as max instead of hardcoded 5000ms. -- **Text overlay position controls** — TextEditorSheet has Horizontal/Vertical position sliders (0-1 range), wired into TextOverlay save callback. -- **Duration slider in seconds** — TextEditorSheet duration slider displays/operates in seconds (0.5-10s) instead of milliseconds. -- **Stroke slider removed** — Non-functional strokeWidth slider removed from TextEditorSheet (SpannableString has no native stroke support). -- **ShaderEffect.kt GLSL framework** — `ShaderEffect` implements `GlEffect`, wraps GLES 3.0 fragment shader + uniforms map. `ShaderProgram` extends `BaseGlShaderProgram`, creates VAO/VBO once in `configure()`, draws fullscreen quad per frame. Uses `androidx.media3.common.util.Size` (NOT `android.util.Size`). -- **Media3 presentationTimeUs is 0-based** — In Transformer export with ClippingConfiguration, `presentationTimeUs` in effects starts from 0 for each clip (not the original media timestamp). Verified by working keyframe opacity and text overlay timing. -- **Transition shaders use uTime for progress** — `uTime = presentationTimeUs / 1_000_000f` (seconds). Progress computed as `uTime * 1000000.0 / uDurationUs`. `uDurationUs = transition.durationMs * 1000f`. After transition duration, progress clamps to 1.0 (fully revealed, no visual change). -- **Wipe shader direction normalization** — `FRAG_WIPE_IN` uses `pos = vTexCoord.x * uDirX + vTexCoord.y * uDirY` with lo/hi range normalization. The `1.04/-0.02` adjusted progress ensures clean black at progress=0 and full reveal at progress=1 (no soft-edge artifact at boundaries). -- **Transition rendering order** — Transitions inserted after regular effects but before opacity/transform/speed/text/Presentation in the videoEffects chain. This means the transition reveals the fully-effected video. -- **GLSL `float a, b` declaration** — Valid in GLSL ES 3.0. Used for `float cs = cos(angle), sn = sin(angle);` in spin/swirl shaders. -- **Heart shape parametric formula** — Uses implicit equation `(x^2 + y^2 - 1)^3 - x^2*y^3 = 0` for clean heart mask in GLSL. Center offset at (0.5, 0.6) for aesthetic framing. -- **Track mute/visible in export** — Video track filtered by `isVisible`, audio from muted video tracks silenced via `VolumeAudioProcessor(volume=0f)`. Audio track filtered by both `isVisible` and `isMuted`. `transmuxAudio` flag derived from filtered audio track state. -- **FrameDropEffect for frame rate** — `FrameDropEffect.createDefaultFrameDropEffect(fps)` added before Presentation in video effects chain. Can only reduce fps (drop frames), not increase. Source fps preserved if target is higher than source. -- **AudioEncoderSettings in Media3 1.5.1** — `DefaultEncoderFactory.Builder.setRequestedAudioEncoderSettings(AudioEncoderSettings)` exists alongside video settings. `AudioEncoderSettings.Builder().setBitrate(int)` controls output audio bitrate. -- **Text overlay fontFamily export** — `TypefaceSpan(overlay.fontFamily)` applied to SpannableString. Android resolves "sans-serif", "serif", "monospace", "cursive" to system fonts. Custom font files would require loading Typeface from assets. -- **Text overlay backgroundColor skip** — `BackgroundColorSpan` only added when alpha channel is non-zero (`color and 0xFF000000 != 0`). Fully transparent (0x00000000) default means no background rendered. -- **Text overlay strokeColor/strokeWidth** — NOT exported. SpannableString has no native stroke support. Would require custom Canvas drawing in a Bitmap-based overlay (not TextOverlay). Documented as known limitation. -- **VolumeOff/VolumeUp AutoMirrored** — `Icons.Default.VolumeOff`/`VolumeUp` are deprecated. Use `Icons.AutoMirrored.Filled.VolumeOff`/`VolumeUp` with explicit import. -- **Effect.enabled already in model** — `Effect` data class has `enabled: Boolean = true` field. `toggleEffectEnabled()` in ViewModel copies effect with `!enabled`. Export filters `clip.effects.filter { it.enabled }`. -- **Track header toggle click targets** — 11dp icons with `clickable` modifier. Small hit target but acceptable for track headers. No `minimumInteractiveComponentSize` override. -- **EditorTopBar project name** — Shown as `Text` with `Modifier.weight(1f)` center-aligned between undo/redo and delete/overflow buttons. Taps open `AlertDialog` for rename. `TextOverflow.Ellipsis` for long names. -- **Add Track overflow submenu** — Separate `DropdownMenu` (not nested). First menu dismisses, then second opens via `showAddTrackMenu` state. Each track type (VIDEO, AUDIO, OVERLAY, TEXT) creates new track via `viewModel.addTrack(type)`. -- **BackHandler priority** — `hasOpenPanel` checks 12 boolean panel states. Priority: dismiss panels > clear tool > deselect clip. `enabled` parameter gates the handler to avoid intercepting when nothing to dismiss. -- **pauseIfPlaying pattern** — Checks `videoEngine.isPlaying()`, calls `videoEngine.pause()`, updates `isPlaying = false` in state. Called at start of every `show*()` method to prevent playback during panel interaction. -- **SubMenuGrid disabledIds** — `Set` parameter. Disabled items get `Modifier.alpha(0.35f)` and no `clickable` modifier. Used for paste_fx when `hasCopiedEffects = false`. -- **Live preview effects** — `VideoEngine.applyPreviewEffects(clip)` builds and applies the selected clip's effects (user effects, color grading, LUT, blend mode, transitions, opacity, transforms) to ExoPlayer via `player.setVideoEffects()`. Called on clip selection, effect add/remove/update/toggle, color grade, blend mode, transition, transform, and opacity changes. Effects are global to the player (not per-clip in playlist), so only the selected clip's effects are shown. -- **Live preview speed** — `VideoEngine.setPreviewSpeed(speed)` applies `PlaybackParameters` to ExoPlayer for real-time speed preview. Updated on speed slider change and during playback when crossing clip boundaries (detected via `getCurrentClipIndex()` in the playhead sync loop). -- **Clip-tracking during playback** — The playhead sync loop now tracks `lastClipIndex`. When ExoPlayer's `currentMediaItemIndex` changes, the current clip's speed and effects are applied automatically, enabling correct preview across multi-clip timelines. -- **ToolPanel "Transform/Motion" tab fixed** — Clip mode "transform" tab now toggles the Motion sub-menu (Transform, Keyframes, Masks, Blend Mode, PiP, Chroma Key) instead of directly opening the Transform panel. -- **ToolPanel "Color" tab wired** — Clip mode "color" tab now toggles the Color sub-menu (Color Grade, Effects, Normalize Audio). Previously had no handler. -- **ToolPanel "Tools" tab wired** — Project mode "project_tools" tab now toggles the Tools sub-menu (Audio Mixer, Beat Detect, Auto Duck, Adjustment Layer, Scopes, Chapters, etc.). Previously had no handler. -- **Media3 upgraded from 1.5.1 to 1.9.2** — Major version bump. `OverlaySettings` renamed to `StaticOverlaySettings`. `ExportTextOverlay.getOverlaySettings()` replaced with `getVertexTransformation()` returning 4x4 column-major GL matrix. Alpha now modulated directly in text ForegroundColorSpan. Added `media3-muxer` dependency (Muxer moved from transformer module). -- **Variable speed export via SpeedProvider** — `SpeedChangeEffect` replaced with `EditedMediaItem.Builder.setSpeed(SpeedProvider)`. When a clip has a `SpeedCurve` with bezier control points, the curve is wired as a per-frame `SpeedProvider` in the export pipeline. Constant speed clips also use SpeedProvider (required by 1.9.x API). Speed curves with ramp up/down/pulse presets now exported correctly. -- **ExoPlayer scrubbing mode** — `VideoEngine.setScrubbingMode(enabled)` wraps `player.setScrubbingModeEnabled()` (Media3 1.8.0+). Enabled during timeline trim drag (`beginTrim()`), disabled on tool change away from TRIM. `beginScrub()`/`endScrub()` exposed for timeline ruler drag. Optimizes seek performance during frequent position changes. - -- **Whisper ONNX auto captions** — `WhisperEngine` provides real speech-to-text when model is downloaded (~75MB whisper-tiny.en from HuggingFace). Auto-downloads encoder_model.onnx + decoder_model.onnx + vocab.json to `filesDir/whisper/`. Falls back to energy segmentation when model not available. AiToolsPanel shows model download status card with progress bar. Uses ONNX Runtime Android 1.17.0. Greedy decoding with timestamp tokens (50364+, each = 0.02s). 30-second chunk processing. GPT-2 byte-level BPE vocab decoded via `decodeGpt2Bytes()`. `INTERNET` permission added for model download. - -- **MediaPipe selfie segmentation** — `SegmentationEngine` wraps MediaPipe Tasks Vision `ImageSegmenter` with selfie_segmenter.tflite (~256KB, auto-downloaded from Google storage). `BG_REMOVAL` EffectType added. Per-frame segmentation during export via `SegmentationGlEffect` (GL readback + CPU segmentation + mask texture upload). Falls back to chroma key when model not available. `ByteBufferExtractor.extract()` for MPImage float confidence values. AiToolsPanel shows segmentation model card. Threshold slider (0.1-0.9) via EffectAdjustment panel. - -- **SegmentationGlEffect FBO safety** — `drawFrame()` saves/restores `GL_FRAMEBUFFER_BINDING` around readback. Copies input to intermediate texture via pass-through shader before `glReadPixels` (avoids GLES feedback loop of sampling and FBO-attaching same texture). Uses separate `copyProgram` and `copyTexture`. -- **BG_REMOVAL skipped in preview** — `applyPreviewEffects` filters out `EffectType.BG_REMOVAL` to prevent per-frame CPU segmentation during live playback (would cause ANR). Only runs during export. -- **bg_replace uses segmentation** — `"bg_replace"` AI tool handler now checks `segmentationEngine.isReady()` and uses `BG_REMOVAL` when model available, falls back to chroma key otherwise. -- **WhisperEngine hardening** — `SessionOptions.close()` after session creation (native memory leak). `NO_SPEECH` token (50362) filtered from text token collection (was decoded as garbled vocabulary text). `Log.e` on corrupt model session creation failure. - -- **User template system** — `TemplateManager` saves/loads/deletes user templates as JSON in `filesDir/templates/`. "Save as Template" in editor overflow menu with name dialog. FAB on project list now opens `ProjectTemplateSheet` (preset grid + "My Templates" section). `createFromTemplate()` creates project with template's track layout + text overlays (clips cleared since source URIs won't exist). `UserTemplate` data class with stateJson from `AutoSaveState.serialize()`. - -- **Proper Room migrations** — Replaced `fallbackToDestructiveMigration()` with explicit `MIGRATION_1_2` (templateId, proxyEnabled), `MIGRATION_2_3` (version), `MIGRATION_3_4` (baseline freeze). DB version bumped to 4 with `exportSchema = true`. Schema exported to `app/schemas/`. `fallbackToDestructiveMigrationFrom(1)` only destroys from ancient v1 installs. -- **Style transfer AI tool** — `analyzeAndApplyStyle()` samples 3 frames, analyzes luminance/saturation/temperature distribution, applies cinematic color grade (contrast boost, temperature shift, slight desaturation, vignette, film grain). Names the detected style (Noir, Warm Cinematic, Moody, Vibrant Film, Cinematic). -- **Neural upscale AI tool** — `analyzeForUpscale()` detects source resolution, recommends next tier (480p->720p, 720p->1080p, 1080p->1440p, 1440p->4K). Updates project resolution + applies sharpening (strength inversely proportional to source resolution). - -- **v2.0.0 bug audit** — Complete 3-agent audit (engine/UI/model layers). Fixed: division-by-zero in energy captions (`windowSamples`, noise analysis `signalSampleCount`), `.average()` crash on empty energy slices, `Clip.durationMs` speed=0 guard (`coerceAtLeast(0.01f)`), bitmap leak in `SegmentationGlEffect.readCopyTextureToBitmap()`, `ExportSheet` empty error string check (`isNullOrBlank`), `AiToolsPanel` null processing tool name fallback, `TemplateManager` silent exceptions now logged. ProGuard: added ONNX Runtime + MediaPipe + javax.lang.model keep/dontwarn rules. -- **BatchExportPanel wired** — `AnimatedVisibility` block added for `state.showBatchExport` in EditorScreen. `startBatchExport()` exports queue items sequentially via `startExport(cacheDir)` loop. -- **VideoScopes frame capture** — `scopeFrame: StateFlow` in ViewModel. `updateScopeFrame()` extracts 256x144 thumbnail from selected clip at playhead via `extractThumbnail()`. Updated on seek and scope toggle. Scopes now display real histogram/waveform/vectorscope data. -- **ProxyEngine wired** — Injected into EditorViewModel. `setProxyEnabled()` triggers `generateProxiesForAllClips()` which iterates all clips and calls `ProxyEngine.generateProxy()`. Clears proxies on disable. "Proxy Edit" menu item added to `projectToolsSubMenu`. - -- **Settings screen** — `ui/settings/SettingsScreen.kt` with default resolution/frame rate/aspect ratio, auto-save toggle + interval slider, proxy resolution selector, about section (version, engine, AI models). Gear icon in ProjectListScreen header. Navigation route `"settings"`. -- **Export platform presets** — `PlatformPreset` quick-select chips (YouTube, TikTok, Instagram Feed/Reels/Story, Twitter, LinkedIn) added to ExportSheet. Auto-populates resolution/fps/codec. Audio-only toggle switch added. -- **Editor onboarding** — Empty project shows centered hint card ("No clips yet — Tap the + button to add media") with VideoLibrary icon. Hides when clips exist or panel is open. Preview panel hidden until clips added. -- **Timeline zoom controls** — Zoom out (-), fit (reset to 1x), zoom in (+) buttons with percentage label. Added above track headers. Uses 0.75x/1.33x multipliers, clamped to 0.1x-10x range. - -- **Settings persistence** — `SettingsRepository` backed by DataStore (`preferencesDataStore`). `SettingsViewModel` with `StateFlow`. All settings (resolution, fps, aspect ratio, auto-save, proxy) persist across rotation and app restarts. `AppSettings` data class with safe enum deserialization. -- **Timeline multi-select** — Long-press on clip toggles multi-select via `toggleClipMultiSelect()`. Orange highlight for multi-selected clips. Action bar shows "N selected" with Delete and Cancel buttons. `selectedClipIds: Set` in EditorState wired to Timeline. `deleteMultiSelectedClips()` with undo support. -- **MediaManager remove unused** — `removeUnusedMedia()` removes empty non-default tracks with undo. Wired to MediaManagerPanel's "Remove Unused" button (was a toast stub). -- **Key files added**: `engine/SettingsRepository.kt`, `ui/settings/SettingsViewModel.kt` -- **Settings wired to EditorViewModel** — `SettingsRepository` injected. Export defaults (resolution, fps) applied on project open. Auto-save interval/enabled respected. Uses `appliedDefaults` flag (not fragile equality check). Only restarts auto-save when enabled/interval actually change (not on every settings emit). -- **ProjectAutoSave accepts interval** — `startAutoSave(projectId, intervalMs)` parameter added. Interval clamped to 10s-600s. -- **README rewritten** — Full feature list matching v2.3.0, accurate tech stack table, build instructions, AI tool descriptions updated (Whisper needs internet for model download). - -## v2.4.0 Bug Audit & Fixes - -### Critical Engine Fixes -- **Blend mode shaders fixed** — All 13 blend modes were self-blending no-ops (e.g., `min(c.rgb, c.rgb)` = no-op). Now use mid-gray (0.5) as virtual blend layer since Media3 doesn't support dual-texture compositing. Each mode now produces a distinct visual effect. -- **Proxy engine now actually downscales** — `ProxyEngine.generateProxy()` was creating full-resolution copies (no `Presentation` applied). Now adds `Presentation.createForHeight()` based on `ProxyResolution.scale`. HALF=540p, QUARTER=270p, EIGHTH=135p. -- **ProxyEngine thread-safe map** — Replaced plain `mutableMapOf` with `ConcurrentHashMap` to prevent `ConcurrentModificationException`. Also improved key generation to reduce hash collision risk (`hashCode_length` instead of just `hashCode`). -- **AudioEffectsEngine massive boxing eliminated** — `pcm.map { }.toFloatArray()` replaced with `FloatArray(size) { }` constructor (avoids boxing millions of Float objects). Same for output conversion. -- **Compressor attack/release coefficients were swapped** — Attack should cause fast envelope rise (needs low coeff for fast tracking), release should cause slow decay (needs high coeff). Was reversed. -- **ZCR speech detection cross-channel bug** — `detectSpeechRegions()` was comparing adjacent samples across channel boundaries in stereo. Now steps by `channels` count. -- **ColorMatchEngine MediaMetadataRetriever leak** — `retriever.release()` was inside `try` before `catch`, so exceptions during `getFrameAtTime()` would leak the native resource. Moved to `finally` block. -- **Mask animations no longer frozen at t=0** — `interpolateMaskPoints(mask, 0L)` was hardcoded. Now uses clip midpoint time as best static approximation for mask position during export. -- **Multi-track export** — Was only exporting first VIDEO and first AUDIO track, silently dropping overlays and additional audio. Now collects all visible video tracks (VIDEO + OVERLAY) and all audio tracks. -- **transmuxAudio fix** — When video track was muted, `setTransmuxAudio(true)` was bypassing the VolumeAudioProcessor that enforced the mute. Now correctly sets transmux based on both audio track presence and video mute state. -- **ShaderEffect crash protection** — Fragment shader compile failure now falls back to passthrough shader instead of crashing the Transformer pipeline. GL attribute location -1 check added to prevent undefined behavior on some GPU drivers. - -### UI Fixes -- **Playhead sync NPE** — `videoEngine.getPlayer()` could return null during initialization; playhead sync loop now uses `?: continue` guard. -- **Color grading undo debounce** — Was calling `saveUndoState()` on every drag event, flooding undo stack. Now uses `beginColorGradeAdjust()` pattern: undo saved once when drag starts. Wired through `ColorGradingPanel.onDragStarted` -> color wheels and curve editor. -- **BackHandler now dismisses scopes** — `showScopes` was missing from `hasOpenPanel` check. Also added to `dismissedPanelState()`. -- **TextEditorSheet stroke controls removed** — Non-functional stroke width/color UI (SpannableString has no native stroke support) was still present despite being documented as removed. Now removed. -- **Batch export improvements** — Items now properly update status to IN_PROGRESS/COMPLETED/FAILED. Output directory changed from `cacheDir` (subject to system cleanup) to `getExternalFilesDir(DIRECTORY_MOVIES)`. - -### Known Remaining Issues -- Blend modes use mid-gray as virtual blend layer (not true dual-texture compositing). Proper compositing requires Media3 Compositor API. -- SmartRenderEngine analysis results not used for actual export (smart render bypass not implemented). -- ProjectArchive.importArchive() not implemented (export-only). -- Speed curve clips don't correctly affect timeline duration calculation (`Clip.durationMs` uses constant speed only). - -## v2.5.0 Feature Expansion (Competitor-Inspired) - -### New AI Engine Features (AiFeatures.kt) -- **Filler word / silence removal** — `detectFillerAndSilence()` uses Whisper for word-level detection of "um", "uh", "like", "you know", etc. Falls back to energy-based silence detection (< -40dB, > 500ms). Returns `RemovalRegion` list. -- **Beat sync automation** — `generateBeatSyncEdits()` uses `AudioEffectsEngine.detectBeats()` to find beats, maps clips across beat positions. Returns `BeatSyncCut` list. -- **Enhanced smart reframe** — `smartReframe()` samples frames at 500ms, uses saliency analysis to find subject center, generates pan/zoom keyframes for aspect conversion. Smooths with moving average. -- **AI auto-edit / highlight reel** — `generateAutoEdit()` analyzes clips for sharpness (Laplacian), motion, face presence (skin-tone). Ranks by quality, optionally syncs to beats. Selects best segments for target duration. -- **AI noise reduction analysis** — `analyzeNoiseProfile()` extracts audio, computes DFT, classifies noise as HISS/HUM/BROADBAND/CLEAN. Recommends DSP effect params. - -### New UI Panels -- **CaptionStyleGallery.kt** — 15 pre-built caption templates (karaoke, word-by-word, bounce, glow, neon, etc.) in 2-column grid with visual previews -- **SpeedPresets.kt** — 10 named speed presets (Bullet Time, Hero Time, Montage, Jump Cut, etc.) with mini Canvas curve previews -- **BeatSyncPanel.kt** — Detect beats button, beat count/BPM stats, visual beat timeline, "Apply Beat Sync" one-tap -- **SmartReframePanel.kt** — 5 aspect ratio cards with platform labels (YouTube, TikTok, Instagram), visual ratio previews -- **AutoSaveIndicator.kt** — Non-intrusive save status indicator (Saving.../Saved/Error) with auto-fade -- **UndoHistoryPanel.kt** — Visual undo history list (like Photoshop), jump-to-state, relative timestamps -- **FirstRunTutorial.kt** — 4-step guided overlay (Add Media, Timeline, Edit & Enhance, Export & Share) - -### New Data Models (Project.kt) -- `CaptionTemplateType` enum (15 styles), `CaptionStyleTemplate` data class -- `SpeedPresetType` enum (10 named presets) -- `SaveIndicatorState` enum (HIDDEN/SAVING/SAVED/ERROR) -- `TutorialStep`, `TutorialHighlight`, `UndoHistoryEntry` - -### ViewModel & Wiring -- 16 new state fields in `EditorState` (panels, modes, analysis states) -- `EditorMode` enum (EASY/PRO) for progressive disclosure -- `isTimelineCollapsed` for collapsible timeline -- All new panels wired via AnimatedVisibility in EditorScreen -- Action dispatch for 7 new actions (beat_sync, auto_edit, smart_reframe, caption_styles, speed_presets, filler_removal, undo_history) -- ToolPanel sub-menus updated with new entries -- Beat sync analyzes audio and auto-splits clips at beat markers -- Smart reframe changes project aspect ratio one-tap -- Speed presets generate SpeedCurve with proper bezier control points - -## v2.5.0 UI Wiring Fixes -- **Easy/Pro mode toggle** — Chip in EditorTopBar between project name and export button. Calls `viewModel.toggleEditorMode()`. Shows mode label colored Mauve (Pro) or Green (Easy). -- **Collapsible timeline** — Toggle row above Timeline with "Timeline" label and expand/collapse icon. AnimatedVisibility wraps Timeline with expandVertically/shrinkVertically. State via `isTimelineCollapsed`. -- **Auto-save indicator wired** — Auto-save getState lambda now triggers `showSaveIndicator(SAVING)` before state capture and `showSaveIndicator(SAVED)` after 500ms delay. -- **Frame step uses project frame rate** — PreviewPanel accepts `frameRate: Int` parameter, computes `frameStepMs = 1000L / frameRate`. Previous/next frame buttons use dynamic step instead of hardcoded 33ms. -- **Timeline track key() calls** — Track headers and main timeline content area use `for (track in tracks) { key(track.id) { ... } }` instead of bare `forEach` for proper Compose recomposition identity. -- **Easy mode tool filtering** — BottomToolArea accepts `editorMode` parameter. In EASY mode, project tabs filtered to edit/audio/text/effects; clip tabs filtered to back/edit/speed/effects/transition. Hides advanced tools (AI, transform, color, aspect, etc.). - -## v2.6.0 UX Polish + New Engines - -### Easy/Pro Mode & Collapsible Timeline -- **Easy/Pro mode toggle** in EditorTopBar. Easy mode hides advanced tools (AI, transform, color grading, aspect ratio). Shows only edit/audio/text/effects/speed/transition. -- **Collapsible timeline** with expand/collapse toggle row. AnimatedVisibility with expandVertically/shrinkVertically. -- **Auto-save indicator wired** to real save events. Shows "Saving..." then auto-fades to "Saved" after 500ms. -- **Frame step uses project fps** instead of hardcoded 33ms. -- **Timeline key() calls** for proper Compose recomposition identity. - -### New Engines -- **EffectShareEngine** (`engine/EffectShareEngine.kt`) — Export/import effect chains + color grades + audio effects as `.ncfx` JSON files. Includes `ImportedEffects` data class. -- **TtsEngine** (`engine/TtsEngine.kt`) — Android TTS wrapper with 8 voice styles (Narrator, Casual, Energetic, Deep, Soft, Fast, Slow, Dramatic). Synthesize to WAV file or preview via speaker. -- **TtsPanel** (`ui/editor/TtsPanel.kt`) — Text input, voice style selector chips, preview button, "Add to Timeline" with progress. -- **FillerRemovalPanel** (`ui/editor/FillerRemovalPanel.kt`) — Detect fillers/silence button, region count display, "Remove All" action. -- **AutoEditPanel** (`ui/editor/AutoEditPanel.kt`) — AI auto-edit highlight reel generator. Shows clip/music/target info cards, generate button. -- **NoiseReductionPanel** (`ui/editor/NoiseReductionPanel.kt`) — AI noise profile analysis + auto-apply DSP filters. - -### Wiring (v2.6.0) -- **TTS fully wired** — TtsEngine + EffectShareEngine injected into EditorViewModel. `showTts()`/`hideTts()`/`synthesizeTts()`/`previewTts()`/`stopTtsPreview()` methods added. TtsPanel AnimatedVisibility in EditorScreen. "tts" action in ToolPanel textSubMenu. -- **Filler removal wired** — `analyzeFillers()` calls `AiFeatures.detectFillerAndSilence()`. `applyFillerRemoval()` splits + removes detected regions. FillerRemovalPanel in EditorScreen. -- **Auto edit wired** — `runAutoEdit()` calls `AiFeatures.generateAutoEdit()`, rebuilds video track. AutoEditPanel in EditorScreen. -- **Noise reduction wired** — `analyzeAndReduceNoise()` calls `AiFeatures.analyzeNoiseProfile()`, applies recommended DSP effects. NoiseReductionPanel in EditorScreen. -- **Effect library wired** — `showEffectLibrary()`/`hideEffectLibrary()`/`exportClipEffects()`/`importEffects()` methods. "effect_library" action dispatched. -- **New EditorState fields** — `showTts`, `isSynthesizingTts`, `isTtsAvailable`, `showEffectLibrary`, `showNoiseReduction`, `isAnalyzingNoise` added. All included in `dismissedPanelState()` and `hasOpenPanel`. - -### Audit Fixes -- **ProjectArchive import** — `importArchive()` extracts .novacut ZIP to target directory, remaps URIs. -- **SubtitleExporter error logging** — Silent catch now logs `Log.e`. -- **SettingsRepository frame rate validation** — `coerceIn(1, 120)`. -- **SettingsScreen deprecated icon** — `Icons.AutoMirrored.Filled.ArrowBack`. - -## v2.7.0 Full Wiring + Pro Features + Engine Fixes - -### All Features Now Wired -- **TTS fully wired** — TtsEngine injected into ViewModel. synthesizeTts/previewTts/stopTtsPreview. TtsPanel in EditorScreen. "tts" in textSubMenu. -- **Filler removal wired** — analyzeFillers() -> detectFillerAndSilence(). applyFillerRemoval() splits + removes. FillerRemovalPanel with detect/apply flow. -- **Auto-edit wired** — runAutoEdit() -> generateAutoEdit(). Rebuilds video track with quality-ranked segments. AutoEditPanel with clip/music/target cards. -- **Noise reduction wired** — analyzeAndReduceNoise() -> analyzeNoiseProfile(). Auto-applies recommended DSP. NoiseReductionPanel. -- **Effect library wired** — exportClipEffects/importEffects via EffectShareEngine .ncfx format. - -### New Pro Engines -- **MultiCamEngine** — Audio waveform cross-correlation sync.

Focus was correctness, data safety, file handling, and export UX rather than reducing warning count. + +### Correctness and data-safety fixes + +- Added `app/src/main/java/com/novacut/editor/engine/FileNaming.kt` with shared filename sanitizers for exports, backups, archives, and shared assets. +- Changed `ProjectAutoSave.saveNow(...)` in `app/src/main/java/com/novacut/editor/engine/ProjectAutoSave.kt` from a `runBlocking` path to an IO-backed suspend save so explicit project saves no longer block the main thread during normal editor use. +- Reworked `app/src/main/java/com/novacut/editor/engine/ProjectArchive.kt` so archive export/import now round-trips the full `AutoSaveState` instead of a partial timeline subset. +- Archive export now bundles all referenced media from clips and image overlays, writes a `media_manifest.json`, and fails fast if required media cannot be opened instead of silently creating incomplete backups. +- Archive import now validates extracted paths against traversal, rewrites imported clip/image URIs to the extracted local copies, clears stale proxy URIs, and cleans up partially created import directories on failure. +- `EditorViewModel.importProjectBackup(...)` now restores and persists more complete state: + - `imageOverlays` + - `timelineMarkers` + - `chapterMarkers` + - `drawingPaths` + - `beatMarkers` + - `playheadMs` +- Imported backups now recalculate duration, rebuild player state, and immediately save the imported project state instead of leaving it transient in memory. + +### Export and UX hardening + +- Fixed a real batch export bug in `app/src/main/java/com/novacut/editor/ui/editor/ExportDelegate.kt`: queued batch items previously ignored `outputName` and just used the normal generic export filename flow. +- Improved the batch export completion summary in `ExportDelegate.kt` so the UI now distinguishes full success, full failure, and mixed outcomes instead of always claiming completion. +- Export output files now use sanitized, collision-safe names derived from the project name or the batch item name instead of hardcoded `NovaCut_` names. +- Hardened `saveToGallery()` in `ExportDelegate.kt`: + - MediaStore writes now fail if the output stream cannot be opened. + - Failed MediaStore inserts are deleted instead of leaving orphaned pending entries behind. + - Pre-Android-10 fallback now writes to the app’s external media folder and triggers a media scan instead of relying on `Environment.getExternalStoragePublicDirectory(...)` without storage permission. + - Toast messaging now reflects the real destination instead of always claiming gallery success. +- Reused the shared filename sanitizer in: + - `app/src/main/java/com/novacut/editor/engine/EdlExporter.kt` + - `app/src/main/java/com/novacut/editor/engine/EffectShareEngine.kt` + - existing backup/archive/template export paths already touched in `EditorViewModel.kt` and `ProjectListViewModel.kt` + +### Test coverage + +- Added JUnit 4 test support in: + -

reserved Windows filenames + - extension preservation + +### Additional editor-state fixes + +- Fixed `EditorViewModel.createCompoundClip()` so the new compound clip is inserted onto a single target track instead of being duplicated onto every track that contained a selected source clip. +- Compound-clip creation now also: + - preserves a valid selected track after compounding + - selects the new compound clip explicitly + - persists the result immediately with `saveProject()` +- Hardened project naming at the view-model boundary: + - `ProjectListViewModel.createProject(...)` + - `ProjectListViewModel.renameProject(...)` + - `ProjectListViewModel.createFromTemplate(...)` + - `ProjectListViewModel.createProjectFromImport(...)` + - `EditorViewModel.renameProject(...)` +- These paths now trim whitespace and fall back to `Untitled` instead of relying solely on UI-side validation. + +### Verification + +Commands run successfully after this pass: + +- `.\gradlew.bat assembleDebug testDebugUnitTest lintDebug --console=plain` +- `.\gradlew.bat installDebug --console=plain` +- `adb -s emulator-5554 shell am start -W -n com.novacut.editor/com.novacut.editor.MainActivity` + +Observed results: + +- Lint summary remained `0 errors, 265 warnings` +- Unit tests now run instead of `NO-SOURCE` +- Debug APK installed successfully on `Medium_Phone_API_36.1` +- Cold launch after this pass: about `2133ms` + +### Remaining known issues after this deep pass + +- AGP is still `8.7.3`, so builds with `compileSdk = 36` succeed but print the known compatibility warning because AGP was officially tested through API 35. +- A larger architectural limitation remains in preview/export rendering: `VideoEngine` currently uses only the first visible visual track (`VIDEO`/`OVERLAY`) as the primary rendered sequence for preview and export. That means true stacked multi-track visual compositing is not fully implemented yet. I confirmed this limitation but did not attempt a safe refactor in this pass because it would require a broader rendering/composition redesign. +- Lint warnings remain dominated by: + - `UnusedResources` + - dependency/version advisories + - `PluralsCandidate` + - one `ObsoleteSdkInt` +- I did not do a bulk dependency upgrade in this pass because that would be higher risk than the targeted reliability fixes above. +- I also did not remove the remaining `UnusedResources` warnings aggressively because some appear tied to unfinished or feature-flagged editor surfaces and would need manual product-level review. + +## Codex Continuation — Template hardening + +### What I changed + +- Repaired the template export caller break introduced by the earlier `TemplateManager.exportTemplateToFile(...)` migration from name-based lookup to ID-based lookup. +- Updated template sharing to pass stable template IDs from: + - `app/src/main/java/com/novacut/editor/ui/projects/ProjectTemplateSheet.kt` + - `app/src/main/java/com/novacut/editor/ui/projects/ProjectListViewModel.kt` + - `app/src/main/java/com/novacut/editor/ui/editor/EditorViewModel.kt` +- Template share/export filenames still use the human-readable template name, but the actual export lookup is now keyed by template ID so duplicate template names no longer cause ambiguous exports. +- Added `TemplateManager.getTemplate(...)` and reused it in the share/export flows so missing or invalid template files fail safely instead of producing misleading success behavior. +- Hardened imported template persistence in `app/src/main/java/com/novacut/editor/engine/TemplateManager.kt`: + - imported templates are now saved with the same schema-version marker as exported templates + - importing a shared template no longer silently overwrites an existing local template when IDs collide + - when an imported template name already exists locally, the imported copy is renamed with an `"(Imported)"` suffix to keep the UI distinguishable +- Added a user-visible failure path in `ProjectListViewModel.createFromTemplate(...)` so corrupted or unsupported templates now show a toast instead of failing silently. + +### Verification rerun + +Commands run successfully after this continuation: + +- `.\gradlew.bat assembleDebug testDebugUnitTest lintDebug installDebug --console=plain` +- `adb -s emulator-5554 shell am start -W -n com.novacut.editor/com.novacut.editor.MainActivity` + +Observed results: + +- Lint summary remained `0 errors, 265 warnings` +- Debug APK installed successfully on the running emulator +- Cold launch after this continuation: about `2126ms` + +### Remaining caution + +- The previously documented `VideoEngine` multi-track visual-compositing limitation still stands; this continuation did not change preview/export composition behavior. + +## Codex Continuation — Premium polish pass + +### What I changed + +- Reduced clutter on the project home in `app/src/main/java/com/novacut/editor/ui/projects/ProjectListScreen.kt` by removing the redundant always-visible floating create button. The main hero actions already stay pinned on screen, so the extra CTA was adding weight without increasing discoverability. +- Added missing project-management polish to the recent-project cards in `ProjectListScreen.kt`: + - project overflow menus now include **Rename** + - renaming happens in-place from the project list instead of forcing users into the editor first + - rename uses the same view-model normalization path as other naming flows +- Reworked `app/src/main/java/com/novacut/editor/ui/settings/SettingsScreen.kt` into a more systematized settings surface: + - section descriptions now explain intent instead of presenting isolated controls + - dropdowns, toggles, sliders, and info rows now use a shared tile layout with icon anchors, clearer hierarchy, and more consistent spacing + - dense choice groups such as track height, thumbnail cache, and export quality now wrap responsively with `FlowRow` instead of assuming one-line layouts + - AI model rows are now proper action tiles instead of text rows with tiny inline actions + - tutorial reset styling now matches the rest of the screen + - the settings hero now uses `Off` instead of the misleading `Cancelled` label when auto-save is disabled +- Tightened editor chrome and timeline responsiveness: + - `app/src/main/java/com/novacut/editor/ui/editor/EditorScreen.kt` now uses a back arrow instead of a home glyph in the editor top bar, which is a better navigation affordance + - top-bar control sizes and spacing were compacted for typical phone widths so the header feels less bulky + - `app/src/main/java/com/novacut/editor/ui/editor/Timeline.kt` now treats standard phone widths as compact mode, and the timeline status/action chips wrap instead of disappearing off the right edge + - after that responsive change, the compact track header width was widened slightly to preserve track-name readability +- Added supporting microcopy in `app/src/main/res/values/strings.xml` for the new settings hierarchy and rename flow. + +### Verification rerun + +Commands run successfully after this continuation: + +- `.\gradlew.bat assembleDebug testDebugUnitTest lintDebug --console=plain` +- `.\gradlew.bat assembleDebug installDebug --console=plain` +- `adb -s emulator-5554 shell am start -W -n com.novacut.editor/com.novacut.editor.MainActivity` + +Observed results: + +- Lint still reports `0 errors, 265 warnings` +- Debug APK installed successfully on `Medium_Phone_API_36.1` +- Cold launch during the premium-polish validation pass was about `2017ms` +- Emulator spot checks were done on the refreshed project home, settings screen, and editor chrome/timeline + +### Remaining design follow-up + +- The project home, settings, and core editor chrome are more cohesive now, but I did not do a full panel-by-panel visual pass across every specialty editor sheet (`AI Tools`, `Audio Mixer`, `Color Grading`, etc.).

aligned the panel API to a simpler one-argument relink callback and updated the `EditorScreen.kt` call site to match, which closes the compile seam introduced by the new relink affordance + - added the panel-specific close content description so accessibility labels no longer fall back to the generic close text + - kept missing assets sorted to the top, let summary metrics wrap with `FlowRow`, and made missing-media action buttons wrap cleanly on narrow screens instead of crowding the card footer + - promoted the clip-usage count into a clearer status pill and tightened the missing-media guidance so the relink action is framed as a status check instead of pretending the full workflow already exists +- Hardened `app/src/main/java/com/novacut/editor/ui/editor/UndoHistoryPanel.kt`: + - added a dedicated close accessibility label using the existing `undo_history_close` string + - made “future” entries visually quieter and non-clickable so the panel no longer implies those states can be jumped to directly after rolling back + - added a newer-steps summary pill plus an inline hint that points users toward Redo when they have rolled back into history + - replaced the inner `LazyColumn` with a regular `Column`, which avoids nesting a lazily scrolling list inside the already scrollable premium sheet and makes this panel less fragile + -

moved the panel onto the newer premium action pattern with a reset icon action and a panel-specific close accessibility label + - replaced the old rigid 2x2 metric rows with an adaptive summary grid that wraps cleanly on narrower widths + - split the controls into clearer framing and presence sections so position/scale do not compete visually with rotation/opacity + - made local numeric formatting explicit and stable inside the tool helpers while touching the shared transform formatting code +- Reworked `app/src/main/java/com/novacut/editor/ui/editor/ToolPanel.kt` for `CropPanel`: + - added a panel-specific close accessibility label and made the current canvas summary pills wrap instead of relying on a fixed row + - replaced the old horizontal preset scroller with adaptive preset cards in a wrapping grid so crop targets remain readable on phones + - moved crop destination labels and aspect-use-case microcopy into string resources instead of leaving them hardcoded in Kotlin +- Hardened `app/src/main/java/com/novacut/editor/ui/editor/EffectLibraryPanel.kt`: + - moved the remaining hardcoded header, state, and action microcopy into string resources + - added a proper panel close content description and rebuilt the action area around responsive workflow cards instead of cramped fixed rows + - made disabled states more honest by explaining whether paste needs a clip, needs a copied buffer, or whether copy/export are unavailable because no clip is selected + - expanded action buttons to full-width targets inside each card so the workflow feels more deliberate and touch-friendly +- Added the supporting strings in `app/src/main/res/values/strings.xml` for transform summaries, crop destinations, effect-library state messaging, and the new close labels. + +### Verification rerun + +Commands run successfully after this continuation: + +- `.\gradlew.bat assembleDebug testDebugUnitTest lintDebug installDebug --console=plain` +- `adb -s emulator-5554 shell am start -W -n com.novacut.editor/com.novacut.editor.MainActivity` + +Observed results: + +- Lint held at `0 errors, 211 warnings` +- Debug APK installed successfully on `Medium_Phone_API_36.1` +- Cold launch after this continuation: about `1931ms` + +### Remaining follow-up + +- I verified build, lint, install, and launch after this pass, but I did not manually open the refreshed `TransformPanel`, `CropPanel`, or `EffectLibraryPanel` on the emulator after the final patchset. +- The next strongest premium-polish candidates are the remaining older editing utilities around transitions, text/tts edge states, and any deeper effect-application flows that still lean on legacy layout patterns or generic messaging. + +## Codex Continuation — transition and TTS polish + +### What I changed + +- Refined `app/src/main/java/com/novacut/editor/ui/editor/ToolPanel.kt` for `TransitionPicker`: + - added a panel-specific close accessibility label and switched the remove action to the newer premium icon treatment + - turned the summary into a clearer “handoff” card with better timing/status pills instead of a bare title plus fixed row + - replaced the old horizontal transition scroller with responsive transition cards in a wrapping grid so styles stay readable on phones + - added a dedicated timing section so duration tuning feels like part of the workflow instead of an isolated slider drop-in +- Reworked `app/src/main/java/com/novacut/editor/ui/editor/TtsPanel.kt`: + - added a panel-specific close label and moved the remaining header/section/status/helper copy into string resources + - fixed a small but real reliability issue by trimming the script before preview/generate, so whitespace-only input no longer behaves like a valid read + - replaced the horizontal voice-style strip with an adaptive card grid and made the delivery actions stack cleanly on compact widths + - made disabled states more honest by surfacing a “write something first” hint instead of just showing silent disabled buttons + -

moved the sheet off its older one-off header/background chrome and onto `PremiumEditorPanel` with a panel-specific close label and a consistent preset action + - added structured overview, property, curve, and selection cards so the editor now explains what is active, what the playhead is doing, and how to add or adjust motion points + - replaced the old horizontal property strip with wrapping chips that stay readable on narrower phones + - replaced the cramped selected-keyframe row with a clearer detail card that surfaces value, time, interpolation, and destructive actions more deliberately + - fixed a real interaction bug in `CurveCanvas`: drag handling now keys the pointer input on the current `selectedKeyframe`, so dragging follows the latest selection instead of potentially using stale captured state + - removed the old hardcoded/locale-unsafe value and time formatting from the selected-keyframe summary in favor of explicit formatting helpers +- Refined `app/src/main/java/com/novacut/editor/ui/editor/TextTemplateGallery.kt` into the newer premium language: + - added a panel-specific close label and moved the remaining gallery-level panel copy into string resources + - replaced the old fixed mode row with responsive mode cards that stack on narrower widths + - replaced the category scroller with a wrapping chip layout so filters feel less cramped and more discoverable on phones + - upgraded both template collections from fixed two-column grids to adaptive grids, and added an explicit empty state so future sparse categories fail gracefully instead of looking broken + - made summary and card metadata chips wrap instead of relying on rigid rows, and moved category summaries out of hardcoded Kotlin helpers into resources + - made the “insert at” time formatting explicit to avoid a locale-default lint regression while keeping the user-facing UI consistent +- Added the supporting strings and plurals in `app/src/main/res/values/strings.xml` for the new keyframe/template copy without introducing new lint warnings. + +### Verification rerun + +Commands run successfully after this continuation: + +- `.\gradlew.bat assembleDebug --console=plain` +- `.\gradlew.bat testDebugUnitTest lintDebug installDebug --console=plain` +- `adb -s emulator-5554 shell am start -W -n com.novacut.editor/com.novacut.editor.MainActivity` + +Observed results: + +- Lint held at `0 errors, 211 warnings` +- Debug APK installed successfully on `Medium_Phone_API_36.1` +- Cold launch after the final rerun: about `2115ms` + +### Remaining follow-up + +- I verified build, lint, install, and launch after this pass, but I did not manually open the refreshed `KeyframeCurveEditor` or `TextTemplateGallery` on the emulator after the final patchset. +- The next strongest premium-polish candidates are the remaining overlay-style utilities and any deeper editor flows that still rely on legacy interaction language, especially the smaller analysis/measurement surfaces that have not yet been brought onto the newer premium panel pattern. + +## Codex Continuation — scopes, snapshots, and blend-mode polish + +### What I changed + +- Rebuilt `app/src/main/java/com/novacut/editor/ui/editor/VideoScopes.kt` around a more premium floating overlay: + -

added honest waiting, analyzing, and live-render states so the overlay now explains what it is doing instead of feeling blank or abrupt + - added calmer scope-specific descriptions for histogram, waveform, and vectorscope, plus a real loading state with progress feedback +- Reworked `app/src/main/java/com/novacut/editor/ui/editor/SnapshotHistoryPanel.kt` into a cleaner recovery/history workflow: + - moved the panel onto a fully string-backed premium shell with clearer overview copy and a panel-specific close label + - replaced the nested lazy list inside the already-scrollable sheet with a simple sorted history stack to avoid utility-style nested scroll behavior + - added snapshot overview chips for count and latest state so the panel feels like a restore surface instead of a raw list + - trimmed custom snapshot names before save and kept the fallback timestamp name path for blank input + - fixed a real interaction issue by removing whole-card restore taps from snapshot rows, so `Restore` and `Delete` no longer compete for the same gesture target +- Refined `app/src/main/java/com/novacut/editor/ui/editor/BlendModeSelector.kt`: + - finally wired the existing blend-mode close accessibility string into the panel + - added a structured current-state summary with current mode, current section, and total mode count + - replaced the rigid two-column chunking with an adaptive wrapping layout so blend cards scale more gracefully across phone widths + - increased card touch area and moved the sheet onto the same calmer panel rhythm as the other premium editor utilities +- Added the supporting strings and plurals in `app/src/main/res/values/strings.xml` for the new snapshot, blend-mode, and video-scopes copy. + +### Verification rerun + +Commands run successfully after this continuation: + +- `.\gradlew.bat assembleDebug --console=plain` +- `.\gradlew.bat testDebugUnitTest lintDebug installDebug --console=plain` +- `adb -s emulator-5554 shell am start -W -n com.novacut.editor/com.novacut.editor.MainActivity` + +Observed results: + +- Lint improved to `0 errors, 208 warnings` +- Debug APK installed successfully on `Medium_Phone_API_36.1` +- Cold launch after the final rerun: about `2000ms` + +### Remaining follow-up + +- I verified build, lint, install, and launch after this pass, but I did not manually open the refreshed `VideoScopesOverlay`, `SnapshotHistoryPanel`, or `BlendModeSelector` on the emulator after the final patchset. +- `ScopeType` labels and some blend-mode metadata remain Kotlin-defined rather than fully resource-backed, so a future localization sweep could still tighten those surfaces further. + +## Codex Continuation — reliability, persistence, and export hardening (2026-04-16) + +### What I changed + +- Hardened release and external-input safety: + - removed the insecure release-signing fallback that could silently use the bundled `novacut-release.jks` plus default credentials + - tightened `MainActivity` import handling so `ACTION_VIEW` only accepts readable `content://` `video/*` inputs + - size-bounded imported effect packages and sanitized imported LUT filenames to block path traversal +- Reworked export/share correctness in `app/src/main/java/com/novacut/editor/ui/editor/ExportDelegate.kt` and `app/src/main/java/com/novacut/editor/engine/ExportService.kt`: + - fixed batch GIF export completion so queued GIF jobs no longer hang waiting on the wrong engine state + - made cancellation and setup failures delete partial output files + - routed PNG/JPEG/GIF outputs through the correct image MIME types and MediaStore collections instead of always treating them like videos + - made export notifications and share intents open the actual produced artifact + - added `cache/frames` FileProvider support so captured still frames can be shared safely +- Strengthened recovery and archive safety: + - made autosave/backup restore more defensive in `ProjectAutoSave.kt` + - hardened `ProjectArchive.kt` against duplicate zip entries, path traversal, oversized text payloads, excessive entry counts, and oversized total extracted content + - added bounded shared IO helpers in `BoundedIo.kt` + - ensured failed archive imports clean up partial extracted content +- Hardened template and file persistence: + - added `AtomicFiles.kt` and switched template/autosave/model replacement paths onto stronger replace semantics instead of brittle delete-and-rename flows + - bounded template import/load size and made template writes/export more reliable + - wrapped template save-from-editor flows with user-visible failure handling in `AiToolsDelegate.kt` +- Improved model download resilience: + - inpainting, segmentation, and Whisper model downloads now validate HTTP success, reject empty/truncated/suspiciously tiny files, and avoid downgrading a previously good model state on refresh failure +- Reduced crash risk: + - removed more `!!`-based UI/engine assumptions from `VideoEngine.kt`, `KeyframeCurveEditor.kt`, and `MarkerListPanel.kt` + - validated imported projects before creating them so unreadable or non-visual media does not produce broken project shells + - made settings reads recover cleanly from DataStore corruption instead of failing the whole flow +- Added focused test coverage: + - `app/src/test/java/com/novacut/editor/engine/ExportFileTypeTest.kt` + - `app/src/test/java/com/novacut/editor/engine/BoundedIoTest.kt` + - `app/src/test/java/com/novacut/editor/engine/AtomicFilesTest.kt` + - updated GitHub Actions to run `testDebugUnitTest` + +### Verification rerun + +Commands run successfully after this continuation: + +- `.\gradlew.bat testDebugUnitTest` +- `.\gradlew.bat assembleDebug assembleRelease` +- `.\gradlew.bat lintDebug` + +Emulator verification completed: + +- relaunched `Medium_Phone_API_36.1` +- reinstalled `app-debug.apk` +- explicitly launched `com.novacut.editor/.MainActivity` +- confirmed `topResumedActivity=ActivityRecord{... com.novacut.editor/.MainActivity ...}` + +### Remaining follow-up + +- AGP is still `8.7.3`, so the project builds cleanly with `compileSdk = 36` but continues to print the known compatibility warning because that AGP line was officially tested through API 35. +- I reverified build, test, lint, install, and launch after this pass, but I did not do a full manual round-trip through long exports, archive restore UI, or interrupted model downloads on device after the final patchset. +- The new model minimum-size guards are intentionally conservative; if upstream model packaging changes materially, those thresholds may need a small follow-up adjustment rather than a logic rewrite. + +--- + +## Audit Pass 3 — 2026-04-16 + +Continuation audit from commit `6034d3c`. Focused on correctness, cancellation, and state-lifecycle bugs across the export pipeline and FileProvider configuration. + +### Bugs found and fixed + +#### 1. Camera capture crash (CRITICAL) +**File:** `app/src/main/res/xml/file_paths.xml` + +Prior audit moved camera capture storage from `cacheDir/camera/` to `filesDir/media/` (in `MediaPicker.kt`) but did not update the FileProvider XML. The stale `` entry no longer matched the actual write path, causing `IllegalArgumentException: Failed to find configured root` at runtime when the user tries to record video via the system camera. + +**Fix:** Replaced with ``. + +#### 2. GIF export uncancellable (HIGH) +**File:** `app/src/main/java/com/novacut/editor/ui/editor/ExportDelegate.kt` + +GIF export ran entirely within ExportDelegate's coroutine scope, bypassing VideoEngine entirely. `cancelExport()` only called `videoEngine.cancelExport()`, which had no effect on the GIF path. Users pressing Cancel during a GIF export saw no response. + +**Fix:** +- Track the GIF coroutine job via `@Volatile gifExportJob` field +- `cancelExport()` now cancels the GIF job before calling `videoEngine.cancelExport()` +- Added `ensureActive()` check between GIF frames for cooperative cancellation +- Added `CancellationException` handler that cleans up the partial GIF file and sets CANCELLED state +- `gifExportJob` cleared in `finally` block + +#### 3. Transformer listener race condition (MEDIUM-HIGH) +**File:** `app/src/main/java/com/novacut/editor/engine/VideoEngine.kt` + +`Transformer.Listener.onCompleted()` and `onError()` only guarded against `CANCELLED` state, but the export progress poll loop can also set `ERROR` (on timeout). A late-arriving Transformer callback after timeout could overwrite the ERROR state with COMPLETE, causing the user to see a success toast for a timed-out export. + +**Fix:** Broadened guard from `if (_exportState.value == ExportState.CANCELLED) return` to `if (_exportState.value != ExportState.EXPORTING) return` in both listener callbacks. + +#### 4. onCleared() clobbers active export state (MEDIUM) +**File:** `app/src/main/java/com/novacut/editor/ui/editor/EditorViewModel.kt` + +`onCleared()` unconditionally called `videoEngine.resetExportState()`, which resets export state to IDLE. If the user navigates away while an export is running, ExportService (which observes the same state flows) would see IDLE instead of the terminal COMPLETE/ERROR/CANCELLED and never stop itself. + +**Fix:** Made `resetExportState()` conditional: only called when `exportState.value != ExportState.EXPORTING`. + +### Verification + +All commands run successfully after fixes: + +- `.\gradlew.bat assembleDebug` — BUILD SUCCESSFUL +- `.\gradlew.bat assembleRelease` — BUILD SUCCESSFUL +- `.\gradlew.bat testDebugUnitTest` — BUILD SUCCESSFUL (4 test suites pass) +- `.\gradlew.bat lintDebug` — BUILD SUCCESSFUL, 0 errors, 205 warnings (down from 208) + +### Codebase review (no changes needed) + +The following files were read and verified as correct: + +- `ExportService.kt` — Foreground service lifecycle and state observation are sound +- `ProjectArchive.kt` — Traversal/size/count limits from prior audit are intact +- `MainActivity.kt` — Intent validation (content:// + video/* MIME) is correct +- `ProjectAutoSave.kt` — Mutex, atomic writes, backup recovery all robust +- `TemplateManager.kt` — Atomic writes and import normalization correct +- `SettingsRepository.kt` — IOException recovery intact +- `EffectShareEngine.kt` — 1MB import size limit correct +- `InpaintingEngine.kt` — Model download validation correct +- `BoundedIo.kt`, `AtomicFiles.kt`, `FileNaming.kt` — Utility code sound +- `ProjectDatabase.kt` — Room DB v5 migration chain correct +- `MediaPicker.kt` — Camera capture writes to `filesDir/media/` (now matches FileProvider) +- `ExportConfig.kt`, `FrameCapture.kt`, `ExportFileType.kt` — No issues + +### Remaining risks + +1. **GIF memory pressure** — GIF encoding holds all frames as Bitmaps in memory. Large/long GIF exports on low-memory devices could OOM. Mitigation would require streaming to disk or frame-at-a-time encoding. +2. **Multi-track video compositing** — Export collects all visible video tracks but Media3 Transformer renders them sequentially (not composited). True overlay/PiP requires the Compositor API. +3. **AGP 8.7.3 + compileSdk 36** — Builds clean but prints compatibility warning. Upgrade to AGP 8.8+ when stable. +4. **Integration test coverage** — Unit tests cover utilities but no instrumented tests exist for export pipeline, auto-save recovery, or FileProvider URI resolution. +5. **clip.isReversed not exported** — Known limitation (Media3 has no reverse playback in Transformer).

Separate from the main [ROADMAP.md](ROADMAP.md) (which covers ML dependency integration tiers). This doc tracks the cross-pollination initiative: taking proven patterns from the 190+ sibling projects and adapting them for an Android video editor. + +**Current version:** v3.49.0 (April 2026) + +**Executive summary:** Four waves of exploration across ~30 sibling projects have yielded **10 shipped features** (spread across v3.46/47/48), **~35 backlog candidates** spanning Tier 1 quick wins to Tier 3 strategic bets, and a running list of un-surveyed targets for Wave 5. Each roadmap entry names its source project so the team can go back and inspect the original implementation pattern. Active waves of work: + +- **Waves 1–2 (shipped & planned):** export controls (target-size, ETA, filename tokens), text templates, scratchpad notes, recovery UI, preset grouping. +- **Wave 3:** frame-preview grid, export pre-flight report, usage analytics, EXIF/GPS ingest, branching undo tree, markdown reports, geo-tag map, preset marketplace, AI edit coach. +- **Wave 4:** contact-sheet export, clip filter chips, multi-pane preview grid, encrypted project archive, output profile pipelines. + +**Conventions:** +- Effort tiers: **S** = 1–3 hours, **M** = half/full day, **L** = multi-session feature +- Integration point = file/class where the feature lands +- Source project links back to `Z:\repos\` + +--- + +## 0.

Tier 1 — Quick Wins (S effort) + +Short, self-contained, no new dependencies. Targets for **v3.47.0 – v3.48.0**. + +### 1.1 Output path macros (extended) +**Source:** EXTRACTORX +**Why:** Current filename template uses token replacement. Extend tokens to include `{projectFolder}`, `{sourceName}` (first clip's source filename), `{duration}`, `{sizeMB}` for post-render macro-substitution. +**Integration:** Extend `ExportDelegate.applyFilenameTemplate()` — add post-export rename step for tokens that need the final file size. +**Effort:** S + +### 1.2 Auto-categorization tags on clips +**Source:** FileOrganizer +**Why:** Tiered classifier (extension → keyword → fuzzy-match) inspires auto-tagging clips by filename keywords ("tutorial", "gaming", "interview"). Adds a chip row on timeline clips + filter on ProjectListScreen. +**Integration:** `Clip.autoTags: List` field + keyword rule table in new `ClipAutoTagger.kt`. Runs on clip-add in `ClipEditingDelegate`. +**Effort:** S + +### 1.3 Interpolation preset discoverability pass — ✅ shipped in v3.48.0 +**Source:** ClipForge +**Shipped:** SpeedCurveEditor split into Ramps (Ramp Up/Down, Pulse) + Constants (Slow Mo, 2×, 4×). KeyframeCurveEditor dropdown divided into Cinematic / Fades / Emphasis with subheaders and dividers. No behavior change — pure discoverability polish. + +### 1.4 Multi-volume media sequence detection +**Source:** EXTRACTORX (split-archive grouping) +**Why:** Users with GoPro/drone footage get `.MP4` chunks named `GH010100.MP4`, `GH020100.MP4`. Auto-detect sequence → offer one-click merged-import (concatenates into a single timeline clip). +**Integration:** `MediaPicker` post-selection pass — regex-match common camera patterns → prompt "Merge 8 related clips?" → add as concatenated sequence via existing merge logic. +**Effort:** S + +### 1.5 Timeline activity anomaly watcher +**Source:** HostShield (rolling-baseline anomaly detection) +**Why:** Detect bulk-deletes (>10 clips in <5 min), mass-effect-removal, accidental project wipes → show "Undo bulk change?" snackbar with one-tap revert. Uses existing undo stack. +**Integration:** New `EditorActivityMonitor.kt` — track operation counts in rolling window inside `EditorViewModel`. Snackbar on threshold exceeded. +**Effort:** S + +### 1.6 Crash-log visible recovery UI — ✅ shipped in v3.47.0 +**Source:** FaceSlim / GitForge +**Shipped:** Added `PanelId.RECOVERY_DIALOG` + AlertDialog in `EditorScreen`. Opens on project load when `autoSave.loadRecoveryData()` returned non-empty content. Buttons: Keep recovered / Discard. +**Integration:** `EditorViewModel.dismissRecoveryDialog(recover)` — discard path calls `autoSave.clearRecoveryData(projectId)`. + +--- + +## 2. Tier 2 — Medium Wins (M effort) + +New engines, new panels, or non-trivial state-model changes. Targets for **v3.49 – v3.52**. + +### 2.1 Unified preset library (effect chains + color grades + export configs) +**Source:** Claude-Ultimate-Enhancer / FaceSlim / ImageForge +**Why:** Currently NovaCut has scattered preset systems — text templates, speed presets, keyframe presets, LUT presets, platform export presets. Unify under `PresetLibrarySheet` with categories, search, favorites, and user-saved presets (JSON in `filesDir/presets/`). +**Integration:** New `PresetManager` (singleton) + `PresetLibrarySheet` panel. Extends existing `TemplateManager` to cover `EffectChain`, `ColorGrade`, `ExportConfig`, `AudioMixerProfile`. +**Effort:** M + +### 2.2 Watermark / branding overlay with presets +**Source:** ImageForge + WallBrand +**Why:** Content creators need branded watermarks (logo + handle + position presets — corner, animated, tiled). Burn-in at export. Saves watermark presets per-project or globally. +**Integration:** New `WatermarkOverlay` model (image + text + opacity + position + animation) → `WatermarkEffect` mapped in `EffectBuilder.buildVideoEffect()` as OverlayEffect during export. New `WatermarkPanel` Composable. +**Effort:** M + +### 2.3 Duplicate-clip detector with perceptual hashing +**Source:** DuplicateFF / FileOrganizer +**Why:** 5-stage pipeline (size → prefix SHA256 → suffix → full hash → pHash diff) finds identical and near-duplicate clips across a project. Show "3 similar clips" badge in gallery; let user batch-remove or merge-aware edit. +**Integration:** New `ClipDedupeEngine.kt` — runs in background `WorkManager` task. pHash stored in Room as `Clip.pHash: Long?`. Surfaced via `DedupePanel` or warning banner. +**Effort:** M + +### 2.4 Live in-canvas text editing (double-tap to edit) +**Source:** PDFedit +**Why:** Current flow requires opening `TextEditorSheet`. Double-tap on a text overlay in the preview → inline-editable text box with keyboard + drag-corner resize for stickers. Matches PowerDirector and CapCut UX. +**Integration:** `PreviewPanel` gains a gesture layer for overlays; new `InlineTextEditOverlay` Composable reuses `TextOverlay` state. Undo-aware via existing `saveUndoState("Edit text")`. +**Effort:** M + +### 2.5 Watermark / subtitle removal via region inpainting +**Source:** GeminiWatermarkRemover / VideoSubtitleRemover +**Why:** NovaCut has `InpaintingEngine` — extend with a "draw mask → inpaint across frames" AI tool. Three-stage NCC detection (GWR) + reverse alpha blending `(I - α·255)/(1-α)` for static watermarks; per-frame inpaint for moving subtitles. +**Integration:** New `aiRemoveWatermark(maskRect)` in `AiToolsDelegate` → reuses existing `InpaintingEngine.inpaintFrame()`. UI: new AI tool card + mask-draw overlay. +**Effort:** M + +### 2.6 Lossless stream-copy trim path +**Source:** ClipForge +**Why:** When a clip has **no** effects, transforms, keyframes, or color grading and is only trim+concat, use `MediaMuxer` stream-copy instead of full Media3 re-encode. Result: 50–100× faster exports for trim-only edits. +**Integration:** New `StreamCopyExporter.kt` selected in `VideoEngine.export()` when `tracks.all { it.clips.all { clip -> clip.isStreamCopyEligible() } }`. +**Effort:** M (tricky edge cases: timebase, keyframe boundary snapping) + +### 2.7 Auto-sequence detection enhanced with drag-drop merge +**Source:** Multistreamer (grid/synced layouts) + MediaDL (codec detection) +**Why:** On media-picker drag of multiple clips, detect if they share source session (same camera, close timestamps, consecutive filenames) → one-tap merge as single timeline clip. +**Integration:** `MediaPickerSheet` post-pick analyzer using `MediaMetadataRetriever` for creation-time + matching codec/resolution. Dialog: "Merge these 5 clips?" +**Effort:** M + +### 2.8 Frame-skip mask reuse for AI tools +**Source:** AlphaCut +**Why:** Segmentation, motion-tracking, stabilization run per-frame; processing every frame is 80% of their cost. Reuse mask across N frames with temporal smoothing (deque + gaussian blending) — 3–5× speedup. +**Integration:** `SegmentationEngine` + `StabilizationEngine` + motion tracker in `AiFeatures.kt` gain `frameSkip: Int` + `temporalSmoothFrames: Int` params. `SegmentationGlEffect` buffers last-N masks for interpolation. +**Effort:** M + +### 2.9 Theme variant presets +**Source:** DarkReaderLocal / stylebot +**Why:** Add a few Catppuccin variants (Latte light, Frappe, Macchiato, Mocha — current) + optional "AMOLED black" and a per-project theme override. Stored in `SettingsRepository`. +**Integration:** Extend `ui/theme/Theme.kt` with `ThemeVariant` enum + `LocalThemeVariant` CompositionLocal. New Settings toggle. +**Effort:** M (every Mocha color reference becomes a token lookup) + +### 2.10 VFX particle overlays (fireflies, sparkles, embers) +**Source:** Aura (`VfxParticleRenderer`) +**Why:** Decorative 30fps Canvas particle effects with phase animation. Export-only (not real-time preview). Compliments existing effect system. +**Integration:** New `ParticleEffect` entries in `EffectType` + `ParticleGlEffect` for GL path. UI: new section in `EffectLibraryPanel`. +**Effort:** M + +### 2.11 Social-media platform codec fallbacks +**Source:** MediaForge / VideoCrush +**Why:** Probe device encoder capability at startup; gracefully degrade HEVC → H.264 on devices without hardware HEVC encoders. Log choice to user ("Exporting in H.264 — HEVC not supported on this device"). +**Integration:** `VideoEngine.probeEncoders()` at init; `ExportConfig.getAvailableCodecs()` already does the first half — extend with auto-degrade fallback in `startExport`. +**Effort:** M + +--- + +## 3. Tier 3 — Strategic Bets (L effort) + +Multi-session features or new core systems. Targets for **v4.x**. + +### 3.1 Scheduled / deferred batch export +**Source:** AlarmClockXtreme +**Why:** Queue batch exports for off-peak hours ("Export at 2 AM"). Exact AlarmManager for deadlines + WorkManager for flexible renders. Important for long 4K/AV1 renders that drain battery. +**Integration:** New `ScheduledExportScheduler` + `ScheduledExportWorker` (extends existing `ProxyGenerationWorker` pattern). Permission handling (`SCHEDULE_EXACT_ALARM` API 31+). UI: schedule picker in `BatchExportPanel`. +**Effort:** L + +### 3.2 Real-time multi-device collaborative editing +**Source:** Multistreamer (sync state across viewers) +**Why:** Sync timeline zoom, playhead, active clip across phone + tablet for review sessions. Not full collab-edit — review-mode sync first. +**Integration:** New `CollaborativeSession` module with WebSocket/Gun.js; `EditorViewModel` publishes state deltas; read-only peer view. +**Effort:** L + +### 3.3 Hierarchical tag + search for clip library +**Source:** Bookmark-Organizer-Pro +**Why:** At 100+ clips per project, flat gallery breaks down. Nested tags (Events > Wedding > Ceremony), boolean search (wedding AND ceremony NOT rehearsal), saved smart filters. +**Integration:** New `ClipTag` model + Room table. `TagPickerSheet` + `SmartFilterEditor`. Extend `ProjectListViewModel` search to boolean-grammar. +**Effort:** L + +### 3.4 Unified format ingest (HEIC/HEIF/AVIF/WebP/JXL) +**Source:** HEICShift +**Why:** Modern cameras and iPhones export HEIC/HEIF; web assets are often AVIF/WebP. Auto-convert on import to a NovaCut-friendly format, preserving EXIF/ICC/XMP. +**Integration:** `MediaPicker` post-selection convert via new `UniversalFormatBridge`. Uses existing `FFmpegEngine` for unsupported formats. +**Effort:** L (requires FFmpeg decoder fleshout) + +### 3.5 Advanced anomaly & health heuristics +**Source:** HostShield (baseline + rolling) +**Why:** Go beyond bulk-delete detection — detect render-blocking effect stacks (20+ effects on one clip), OOM-risky project sizes (500+ clips, 10GB+ media), fragmented timelines — and surface "Project health" indicator in gallery. +**Integration:** New `ProjectHealthAnalyzer` that runs on auto-save. Emits `HealthReport` (surfaced as gallery card badge). +**Effort:** L + +### 3.6 Per-frame GIF timing control with keyframe animator +**Source:** GifStudio / GifText +**Why:** Current GIF export is uniform 15/20fps. Enable per-frame delays (frames 1–5 at 100ms, 6–10 at 50ms) for dramatic-pause meme timing. Built on existing keyframe engine. +**Integration:** Extend GIF export path in `ExportDelegate` to consume `SpeedCurve` / per-frame delay list; new `GifTimingEditor` panel. +**Effort:** L + +--- + +## 4.

Wave 2 — Additional Research (April 2026) + +Second-pass exploration of qBittorrent-Vanced/Enhanced-Edition, KeepSyncNotes, NeonNote, LogLens, Vigil, PathForge, UniFile. + +### 6.1 Adaptive render speed limit (Tier 1) +**Source:** qBittorrent-Vanced (speed-limit presets) +**Why:** Export rendering can thermal-throttle the device. Add Low/Medium/High/Max presets that throttle encoder by injecting brief sleeps between frames. Real-time indicator above progress bar: "Speed: 45% (Limit: 75%)". +**Integration:** `ExportSheet` dropdown above progress bar; `VideoEngine.export()` respects a throttle param (`Thread.sleep(throttleMs)` in progress callback). +**Effort:** S + +### 6.2 File encoding auto-detect on subtitle import (Tier 1) +**Source:** NeonNote (8-level encoding pipeline) +**Why:** Imported `.srt` files with GB2312, Shift-JIS, or Windows-1252 show as garbled text. BOM check → UTF-8 attempt → fallback chain prevents the garble. +**Integration:** New `FileEncodingDetector.kt` called from `SubtitleExporter`/importer path. Store `Subtitle.encoding: String`. +**Effort:** S + +### 6.3 Preview panel variable opacity (Tier 1) +**Source:** NeonNote (window opacity slider) +**Why:** Useful for checking overlay alignment against UI — pinch-zoom + Alt-modifier to blend video with underlying editor chrome. +**Integration:** `PreviewPanel` pointerInput + `Project.previewOpacity: Float` persisted in Room. +**Effort:** S + +### 6.4 Scratchpad notes per project — ✅ shipped in v3.47.0 +**Source:** KeepSyncNotes +**Shipped:** `Project.notes` Room-migrated field (MIGRATION_5_6), `ScratchpadSheet` Composable with 750ms-debounced auto-save, overflow menu entry. +**Remaining:** Optional sidecar `.txt` bundle on export is still pending — deferred to a later wave. + +### 6.5 Export batch queue with priority reorder & pause/resume (Tier 2) +**Source:** qBittorrent-Enhanced-Edition (queue management + bandwidth limits) +**Why:** Existing `BatchExportPanel` runs jobs sequentially — no reorder, no pause/resume, no persistent queue across app restarts. Add Room-backed queue with drag-reorder, pause/resume per job, priority levels. +**Integration:** Promote `batchExportQueue` to a Room table with stable IDs. New `QueueManagerService` (foreground service) consumes queue via WorkManager. `BatchExportPanel` → `BatchExportQueueSheet` with drag handles + priority chips. +**Effort:** M + +### 6.6 Multi-level undo timeline with visual rollback (Tier 2) +**Source:** NeonNote (undo timeline visualization) +**Why:** Linear undo stack forces sequential step-back. Visual card shows "Trim (2m ago) → Add Music (1m ago) → Color Grade (now)" — tap any point to instant-rollback. +**Integration:** Extend `EditorViewModel` undo stack to capture label + timestamp. New `UndoTimelineSheet` Composable; horizontal scroll list with highlighted current position. +**Effort:** M + +### 6.7 Export config snapshot & before/after diff (Tier 2) +**Source:** UniFile (undo timeline with preview) + NeonNote (session restore) +**Why:** "Last export was 1080p H.264. This one is 4K HEVC — 5× longer, 4× file size." Warn on drastic config changes so users don't accidentally overwrite a good preset. +**Integration:** New `ExportSnapshot` Room table (ExportConfig + first-frame thumbnail bytes + timestamp). `ExportSheet` shows diff card on repeat-open; highlights changed fields. +**Effort:** M + +### 6.8 Project health dashboard (Tier 2) +**Source:** LogLens (stats + anomaly detection) + HostShield baseline patterns +**Why:** ProjectListScreen shows health badge: "8 clips, 2.3 GB, 127 effects. Est. render 45m. Warning: clip #5 has 22 effects." Prevents OOM surprises before user hits export. +**Integration:** New `ProjectHealthAnalyzer.kt` runs on auto-save → `HealthReport` Room row → badge in `ProjectListScreen` card. Thresholds: >50 clips, >10GB media, >15 effects per clip, >3 audio tracks. +**Effort:** M + +### 6.9 Subtitle-aware auto-segmentation / scene-cut suggest (Tier 2) +**Source:** LogLens (format detection) + UniFile (metadata + heuristics) +**Why:** Imported SRT — detect sentence boundaries + long pauses via duration heuristic, offer one-tap "Cut clip at each subtitle boundary" for music-video sync workflows. +**Integration:** New `SubtitleSegmentEngine.kt`; `SubtitleSegmentationSheet` showing candidate cuts with preview. Ties into existing `splitClipAtPlayhead` in `ClipEditingDelegate`. +**Effort:** M + +### 6.10 Project template scaffolder (Tier 3) +**Source:** MavenForge (rapid scaffolding) +**Why:** "Start from template" flow at project creation — not just blank. Templates include aspect ratio, track layout, starter effects, placeholder music track, default export config. Differs from text-template gallery (which is per-overlay). +**Integration:** New `ProjectTemplate` model + `ProjectTemplateSheet` (already exists for TextTemplates — extend). Built-ins: "YouTube Vlog", "TikTok Reel", "Wedding Film", "Tutorial", "Product Demo". +**Effort:** L (need curated starter content bundled in assets) + +--- + +## 7. Wave 3 — Additional Research (April 2026) + +Third-pass exploration covering: backend/frontend, kindred, VIPTrack, PillSleepTracker, iOSIconPack, mnamer, FedEx, Doordash-Enhanced, Openshop, SkyTrack, XRayAcquisition, LogLens, Vigil. Some projects (backend/frontend/kindred) appeared to be empty or placeholder scaffolds — candidates below are drawn from the projects that yielded usable patterns. + +### 7.1 Timeline scrubbing frame-preview grid (Tier 1) +**Source:** Openshop (multi-canvas preview) / SkyTrack (grid tile loading) +**Why:** Hold Shift while hovering the timeline → show a 3-wide × 2-tall mini-grid of frames ±3 frames around the cursor (100×100 px each). Faster than scrubbing for precise cut placement. +**Integration:** Extend `PreviewPanel` gesture handling. New `FrameGridComposable` overlaid on `Timeline`. 7-frame cache in `VideoEngine.thumbnailCache`. +**Effort:** S + +### 7.2 Export health pre-flight report (Tier 1) +**Source:** Doordash-Enhanced (fee breakdown transparency) + LogLens (anomaly detection) +**Why:** Before dispatching the render, show: "This will take 47m @ 22 Mbps; bitrate is 3× your last preset; recommended is 8 Mbps for 1080p." Warns on drastic config drift from the previous successful export. +**Integration:** New `ExportHealthReportSheet` shown pre-dispatch in `ExportDelegate.startExport`. Reuses `estimateExportEtaSeconds()` + bitrate comparison against last successful `ExportConfig` (stored in `SettingsRepository`). +**Effort:** S + +### 7.3 Usage activity dashboard with heatmaps (Tier 2) +**Source:** Kindred (event correlation) + VIPTrack (engagement tracking) +**Why:** Understand editing patterns — peak hours, avg session length, clip count per day, drop-off after crashes. Pairs with §3.5 (Project Health Analyzer). Opt-in only, local-only. +**Integration:** New `ProjectActivityAnalyzer.kt` logging `ActivityEvent(type, timestamp, projectId)` to new Room `activity_log` table. `AnalyticsSheet` panel renders hourly heatmap, session-length histogram, and top-used effects. Gated behind `SettingsRepository.analyticsEnabled`. +**Effort:** M + +### 7.4 Clip EXIF / GPS / camera metadata ingest (Tier 2) +**Source:** XRayAcquisition (medical imaging metadata workflows) + mnamer (content matching) +**Why:** GoPro/DJI/smartphone clips ship with rich metadata — GPS, compass, camera model, firmware, date. Parse + store on `Clip.metadata: Map`. Unlocks: filter by camera, batch-rename by date range, geo-tag on map (future §7.7 tie-in). +**Integration:** New `ClipMetadataExtractor.kt` using `MediaMetadataRetriever.extractMetadata()` + `ExifInterface` (for image overlays). Room migration: `Clip.metadataJson: String`. New read-only metadata card in clip detail sheet. +**Effort:** M + +### 7.5 Multi-step undo with branching tree (Tier 2) +**Source:** NeonNote (undo tree visualization) +**Why:** Current linear undo forces sequential reversal. Promote to a branching tree — jump to any ancestor checkpoint, preserve descendant branches. UX is a visual chain of "Trim (2m) → Add Music (1m) → Color (now)" with tap-to-rollback. +**Integration:** Extend `EditorViewModel.undoStack` from `List` to a tree with parent links. New `UndoTimeBranchSheet` Composable rendering a horizontal chain with animated diamond nodes. Subsumes/extends §6.6 — this is the richer implementation of the same concept. +**Effort:** M (non-trivial undo refactor) + +### 7.6 Markdown project-report export (Tier 2) +**Source:** KeepSyncNotes (scratchpad) + LogLens (markdown formatting) +**Why:** Upgrade the §6.4 scratchpad sidecar. Export project as `.md` with: table of contents, clip gallery (base64-embedded thumbnails), effects inventory, per-clip notes with timecode anchors, overall summary. Ideal for archival, review loops, and async collaboration. +**Integration:** New `MarkdownExporter.kt` + "Export as Markdown Report" entry in ExportSheet. Template-based rendering. Uses existing `VideoEngine.extractThumbnail()` + base64 encode. +**Effort:** M + +### 7.7 Geo-tagged clip map view (Tier 3) +**Source:** SkyTrack (2D/3D map overlays + Leaflet dark tiles) +**Why:** For travel / documentary editors, show all project clips pinned on a map (from §7.4 GPS metadata). Tap pin to jump to that clip in the timeline. Useful for visualizing shot coverage. +**Integration:** New `ClipMapSheet` Composable. Uses Mapbox or osmdroid (no Google Maps key required); dark basemap tiles. Pins placed at `Clip.metadata.gps`. Tap → `EditorViewModel.selectClip(clipId)`. +**Effort:** L (new dependency) + +### 7.8 Preset marketplace scaffold (Tier 3) +**Source:** Openshop (e-commerce + in-app asset UI) +**Why:** If NovaCut grows a creator economy, users want to browse/download community effect chains. Stub: browsable gallery of `.novacut-preset` bundles with author, description, rating, download count. Payments/DRM are out-of-scope for v1 — free sharing first. +**Integration:** New `PresetMarketplaceSheet` with paginated card grid. Local: `filesDir/presets/marketplace/` folder. Remote: HTTP endpoint returning JSON `[{name, author, rating, downloadUrl}]`. Depends on §2.1 (unified preset library) landing first. +**Effort:** L + +### 7.9 AI edit-coach suggestions per clip (Tier 3) +**Source:** Kindred (conversation coaching pattern) + NovaCut's existing AI tools +**Why:** For learning editors: inline tips on the selected clip ("Try a faster cut during this dialogue", "Music swell at 0:32 could lead a chorus"). Heuristic-only v1 (clip-length + audio energy + effect density); LLM upgrade is §7.9.1. +**Integration:** New `AiCoachDelegate.kt` next to existing `AiToolsDelegate`. Surfaced as a "Coach" chip in `AiToolsPanel` when a clip is selected. Suggestions cached on `Clip.suggestions: List`. +**Effort:** L + +--- + +## 8. Wave 4 — Additional Research (April 2026) + +Fourth-pass exploration of LaunchPad, ImprovedTube-research, Job-Search, NexRay, ParkerSuite, ClearGem, DeepPurge, AdapterLock, DefenderShield/Control, and revisits of FrameSnap + Multistreamer. Empty/placeholder projects (LaunchPad, ParkerSuite, DeepPurge) produced no candidates; findings below are drawn from the projects that yielded usable patterns. + +### 8.1 Contact-sheet export — ✅ shipped in v3.49.0 +**Source:** FrameSnap +**Shipped:** `ContactSheetExporter.kt` composites 320×180 midpoint thumbnails into a single PNG grid (2/3/4/5/6 columns). Captions: filename (24-char cap) + `M:SS` duration. Dark Catppuccin background. New ExportSheet toggle + button-label swap. Routed through existing filename template + save-to-gallery MediaStore path. + +### 8.2 Clip filter chips — used / unused / duration / effects (Tier 1) +**Source:** Job-Search (`.cat-btn.active` + `.rcard.hidden` visibility pattern) +**Why:** At 50+ clips in a project, users want to filter the project gallery or a pending "Source Clips" bin. Pills: Used on timeline / Unused / Short (<5s) / Long (>60s) / Has effects / No effects. Toggles visibility without navigation cost. +**Integration:** Extend `ProjectListScreen` — new `ClipFilterChips` row above the clip gallery. Filters applied client-side over `ProjectListViewModel.allProjects`. Could also surface inside the MediaManagerPanel for source clips. +**Effort:** S +**Note:** This is the simpler cousin of §3.3 (Hierarchical tag + search). Could ship first as an MVP and evolve into §3.3. + +### 8.3 Multi-pane preview grid (Tier 2) +**Source:** Multistreamer (Brady-Bunch grid layout + synced playhead + featured mode) +**Why:** For projects with 4+ video tracks (multicam, PiP-heavy edits), show 2×2 or 3×3 mini-previews all locked to the same playhead + scrub. Lets editors see every source simultaneously instead of track-isolating. +**Integration:** New `MultiPreviewGrid` Composable, opt-in toggle in the main `PreviewPanel`. Each tile is a lightweight `SurfaceView` playing the same ExoPlayer timeline but visually clipped to its source track. "Featured" tile expands on tap. +**Effort:** M + +### 8.4 Encrypted project archive with biometric unlock (Tier 2) +**Source:** AdapterLock (registry ACL + escalation chain) + Android KeyStore +**Why:** Creators editing sensitive content (medical, legal, pre-release brand work) want a passphrase/biometric lock on the project. Extend `ProjectArchive.exportArchive()` to optionally AES-GCM encrypt; unlock via BiometricPrompt → KeyStore-derived key. +**Integration:** New `ProjectEncryption.kt` wrapping `javax.crypto.Cipher` + Android KeyStore. `ProjectArchive.importArchive()` detects the encrypted magic bytes and prompts biometric. Depends on ProjectArchive fleshout noted in main [ROADMAP.md](ROADMAP.md). +**Effort:** M + +### 8.5 Output profile pipelines (Tier 2) +**Source:** NexRay (13 specialized multi-stage pipelines — each a named chain of transforms) +**Why:** Richer than the current `PlatformPreset` enum. An "Output Profile" is a **named multi-stage pipeline**: e.g. "YouTube Shorts Long" = {trim to 60s, crop 9:16, caption template = Reels Hook, target-size 100MB, codec H.264, sidecar notes.txt}. Users save their own profiles for repeatable workflows. +**Integration:** New `OutputProfile` model aggregating `ExportConfig` + pre-export clip mutations + post-export actions. New "Profiles" tab in `ExportSheet` alongside existing platform-preset chips. 8 built-in profiles + user-saved. +**Effort:** M +**Note:** Super-set of §2.1 (unified preset library) — when §2.1 lands, OutputProfile lives inside its catalog. + +### 8.6 Adaptive render throttle (reinforcement) +**Source:** DefenderControl (phase-based async runspaces) +**Why:** Reinforcement of §6.1. DefenderControl's "run in phases with controllable delays" pattern gives a concrete implementation shape for the Low/Med/High/Max render speed picker — phase the encoder in N-frame chunks with configurable sleep between chunks. +**Integration:** No new roadmap entry — this **informs the implementation** of §6.1. +**Effort:** (tracked under §6.1) + +### 8.7 Hierarchical preset sections (reinforcement) +**Source:** DefenderControl (20+ settings in hierarchical collapsible phases) +**Why:** Reinforcement of §2.1 (unified preset library). Collapsible per-category sections with per-preset enable toggles. +**Integration:** Informs §2.1 UI design. +**Effort:** (tracked under §2.1) + +### Excluded from Wave 4 +- **ClearGem** — too domain-specific; subsumed by §2.5 (watermark removal via inpainting). +- **DeepPurge** — system uninstaller; out of scope. +- **ImprovedTube-research** — no concrete porting targets; YouTube-specific export needs are already covered by the `YOUTUBE_1080` / `YOUTUBE_4K` PlatformPresets. +- **NexRay medical-specific modules (DICOM, dental, vet)** — the architectural pattern is the port, not the domain code. + +--- + +## 9.

For Compose, use `lottie-compose` wrapper. - -### Material 3 / Material You Dynamic Theming - -Key implementation points: - -- Use `dynamicColorScheme()` in Compose to derive colors from user wallpaper (Android 12+) -- Fall back to a custom HostShield brand color scheme (blue/green shield palette) on pre-Android 12 -- Create semantic color tokens: `surfaceBlocked` (red tint), `surfaceAllowed` (green tint), `surfaceWarning` (amber) -- Use M3 Expressive motion: "success swells" for block confirmations, hero transitions between screens -- Dark/light theme should be automatic with M3, but provide manual override -- **Do NOT** mix Jetpack Compose `MaterialTheme` with Glance widgets -- use color resource IDs for widgets - -### Real-Time Query Log Animations - -Inspired by RethinkDNS's near-real-time connection tracker: - -- Use `LazyColumn` with `animateItemPlacement()` for smooth item insertion -- New items slide in from top with fade-in animation -- Color-code entries: green for allowed, red for blocked, amber for cached -- Show app icon + domain + response time inline -- Tapping an entry expands to show full DNS response, TTL, upstream resolver used - ---- - -## 2. Widgets and Quick Settings Tiles - -### Jetpack Glance Widgets - -**Recommended widget set** (3 widgets): - -#### Widget 1: Toggle + Stats Combo (2x2) -``` -+---------------------------+ -| [Shield Icon] HostShield | -| Protected [ON/OFF toggle]| -| Blocked: 3,241 today | -| Queries: 12,847 | -+---------------------------+ -``` - -#### Widget 2: Stats-Only (4x1) -``` -+-----------------------------------------------------+ -| Queries: 12.8K | Blocked: 3.2K | 25.2% | Latency: 23ms | -+-----------------------------------------------------+ -``` - -#### Widget 3: Mini Toggle (1x1) -``` -+--------+ -| [Shield| -| ON] | -+--------+ -``` - -**Glance best practices** (critical): - -- State management: Use `PreferencesDataStore` -- Glance does NOT redraw automatically on state changes -- Theming: Use color resource IDs for dynamic colors, NOT `MaterialTheme` wrapping -- Sizing: Implement `SizeMode.Responsive` with breakpoints for different widget placements -- User interaction: Use `actionRunCallback()` for toggle actions -- Testing: Extend `GlancePreviewActivity` in debug builds for rapid iteration -- Metrics: On Android 16+, leverage `AppWidgetEvent` API for tap/scroll tracking - -### Quick Settings Tile - -Implement `TileService` for VPN toggle (modeled on WireGuard's implementation): - -- Extend `TileService`, require API 24+ -- Set `TOGGLEABLE_TILE` metadata to `true` for accessibility -- Observe VPN tunnel state and update tile icon/label accordingly -- States: Active (green shield), Inactive (grey shield), Unavailable (crossed-out shield) -- Use `isSecure()` check before toggling -- if device locked, use `unlockAndRun()` for safety -- Show brief subtitle: "3.2K blocked" or "Protected" as secondary label -- Handle edge case: if VPN permission not yet granted, launch permission flow from tile tap - ---- - -## 3. Onboarding Flows - -### Recommended Progressive Onboarding Sequence - -Based on patterns from RethinkDNS, Blokada, and security app best practices: - -``` -Screen 1: Welcome - "HostShield protects your device from ads, trackers, and malware" - [Lottie shield animation] - [Get Started] - -Screen 2: VPN Permission - "HostShield uses a local VPN to filter DNS requests. - No data leaves your device." - [Visual diagram: Device -> Local VPN -> Filtered DNS] - [Enable Protection] -> triggers VPN permission dialog - WHY: Address user anxiety about "VPN" terminology upfront - -Screen 3: Battery Optimization Exemption - "For uninterrupted protection, exempt HostShield from battery optimization" - [Step-by-step visual guide with device-specific screenshots] - [Exempt Now] -> launches system battery optimization settings - [Skip for now] -> remind later via notification - WHY: VPN apps killed by Doze = no protection - -Screen 4: Choose DNS Provider (Progressive Disclosure) - Simple mode: "Recommended (Cloudflare DoH)" [one tap] - Advanced mode: [expandable] Custom DoH/DoT/DNSCrypt configuration - WHY: Don't overwhelm newcomers, empower power users - -Screen 5: Blocklist Selection - Preset profiles: "Standard", "Strict", "Family-Safe" - Each shows what it blocks (ads, trackers, malware, adult content) - [Customize later in Settings] - -Screen 6: Done - "You're protected! Here's what HostShield is doing:" - [Live demo of first few blocked queries appearing] - [Explore Dashboard] -``` - -### Key UX Principles from Research - -1. **Short, direct messaging**: "Click here to do this" -- mobile users are impatient -2. **Progressive feature discovery**: Show tooltips for advanced features only when user first encounters them -3. **Contextual hints**: Explain WireGuard proxy, split tunneling, etc. only when user navigates to those screens -4. **Root access flow** (optional): If root detected, offer "Root mode (no VPN slot needed)" as an alternative during setup with clear tradeoff explanation -5. **Rename confusing terms**: RethinkDNS renamed "whitelisting" to "Bypass universal" for clarity -- HostShield should use plain language like "Allow" / "Block" / "Bypass" - ---- - -## 4. Automation and Scheduling - -### Tasker / Intent Integration - -Based on patterns from WireGuard, OpenVPN, and Blokada: - -**Exposed broadcast intents HostShield should support:** - -```kotlin -// Toggle protection -"com.hostshield.action.ENABLE_PROTECTION" -"com.hostshield.action.DISABLE_PROTECTION" -"com.hostshield.action.TOGGLE_PROTECTION" - -// Profile switching -"com.hostshield.action.SET_PROFILE" - extra: "profile_name" -> String - -// DNS provider switching -"com.hostshield.action.SET_DNS" - extra: "dns_url" -> String (DoH/DoT URL or sdns:// stamp) - -// Blocklist management -"com.hostshield.action.ENABLE_BLOCKLIST" -"com.hostshield.action.DISABLE_BLOCKLIST" - extra: "blocklist_id" -> String - -// Query intents (return data) -"com.hostshield.action.GET_STATUS" - returns: "is_active" (bool), "blocked_count" (int), "query_count" (int) -``` - -**Implementation**: ~50 lines per intent using `BroadcastReceiver` -- WireGuard proves this is lightweight. Require a signature-level permission or user opt-in for security. - -### Time-Based Blocking Schedules - -Modeled on parental control patterns from AdGuard and NextDNS: - -``` -Schedule Types: - 1. Focus Mode - Block social media domains during work hours - 2. Sleep Mode - Block all except essential services at night - 3. Family Mode - Enable safe search + adult content blocking (school hours) - 4. Custom - User-defined time windows with specific blocklists - -Implementation: - - Use AlarmManager for exact scheduling (foreground service already running) - - Store schedules in Room database - - UI: Weekly calendar grid with colored time blocks - - Each schedule links to a "Profile" (DNS + blocklist + firewall rules) -``` - -### Location / Wi-Fi SSID-Based Profile Switching - -Inspired by Blokada 5's Networks feature (with improvements on its SSID detection issues): - -``` -Profiles: - "Home" -> Wi-Fi SSID "MyHomeWifi" -> Relaxed blocking (Pi-hole handles rest) - "Office" -> Wi-Fi SSID "CorpWifi" -> Strict blocking + no social media - "Public" -> Any other Wi-Fi -> Maximum protection + force DoH - "Mobile" -> Cellular -> Standard + data-saving mode - -Implementation: - - Register NetworkCallback for connectivity changes - - Match SSID on Wi-Fi connect events (requires ACCESS_FINE_LOCATION on Android 10+) - - Debounce switching (300ms) to avoid rapid toggling during handoffs - - Blokada had bugs with SSID detection -- solve by force-refreshing network info - on connectivity change rather than caching stale values -``` - -### Screen On/Off Rules - -Borrowed from NetGuard's proven implementation: - -- "Block when screen off" per-app toggle (NetGuard's most popular feature) -- "Allow when screen on" per-app toggle -- Register `ACTION_SCREEN_ON` / `ACTION_SCREEN_OFF` broadcast receivers -- Instantly update firewall rules when screen state changes -- Use case: Allow social media only when actively using phone - ---- - -## 5. Backup, Export, and Sync - -### Config Backup/Restore - -**Recommended format**: Encrypted JSON archive (`.hostshield-backup`) - -```json -{ - "version": 2, - "timestamp": "2026-03-25T10:30:00Z", - "app_version": "1.5.0", - "contents": { - "dns_config": { ... }, - "blocklists": [ ... ], - "custom_rules": [ ... ], - "profiles": [ ... ], - "schedules": [ ... ], - "app_rules": [ ... ], - "settings": { ... } - } -} -``` - -**Encryption**: Use `EncryptedSharedPreferences` pattern -- AES-256-GCM with a user-provided passphrase via PBKDF2 key derivation. Alternatively, support Android Keystore-backed encryption for zero-passphrase local backups. - -### Cloud Sync Options - -| Method | Pros | Cons | Priority | -|--------|------|------|----------| -| **WebDAV** (Nextcloud, etc.) | Self-hosted, privacy-friendly, proven pattern (DAVx5) | Requires server setup | High | -| **Google Drive / SAF** | Zero setup for most users | Vendor lock-in, privacy concern | Medium | -| **Custom server** | Full control | Maintenance burden | Low | - -**WebDAV implementation**: Use OkHttp with WebDAV extensions. Config: server URL, username, password, folder path. Support self-signed certificates (DAVx5 pattern). - -### Automatic Backup with WorkManager - -```kotlin -// Schedule periodic backup -val backupWork = PeriodicWorkRequestBuilder( - repeatInterval = 24, // daily - repeatIntervalTimeUnit = TimeUnit.HOURS -) - .setConstraints( - Constraints.Builder() - .setRequiredNetworkType(NetworkType.UNMETERED) // Wi-Fi only for cloud - .setRequiresCharging(false) - .build() - ) - .addTag("auto_backup") - .build() - -WorkManager.getInstance(context).enqueueUniquePeriodicWork( - "hostshield_auto_backup", - ExistingPeriodicWorkPolicy.KEEP, - backupWork -) -``` - -### Sharing Configs Between Devices - -- **QR code**: Encode a shareable config URL/blob as QR code (like DNS stamp `sdns://` format) -- **Share intent**: Export config file via Android share sheet -- **Deep link**: `hostshield://import?config=base64encodeddata` -- **Nearby Share**: For same-household device setup - ---- - -## 6. Logging and Diagnostics - -### Query Log UX - -Modeled on RethinkDNS (best-in-class for Android DNS logging): - -**Features to implement:** -- Real-time streaming feed using `LazyColumn` with `Flow>` -- Color-coded entries: Allowed (green), Blocked (red), Cached (blue), CNAME-cloaked (purple) -- Inline app icon + package name for each query -- Search bar with filters: by app, domain, time range, status (blocked/allowed) -- Tap to expand: full DNS response, TTL, resolver used, latency, DNSSEC status -- Geo IP + ASN info for resolved IPs (as RethinkDNS recently added) -- Export to CSV/JSON with date range filter -- "Block this domain" / "Allow this domain" quick actions on each entry - -**Performance considerations:** -- Use Room database with pagination (`PagingSource`) for historical logs -- Keep only last N entries in-memory for real-time view (ring buffer) -- Background thread for log writes to avoid UI jank -- Configurable retention period (7/30/90 days, or unlimited) - -### Real-Time Log Streaming UI - -``` -+------------------------------------------+ -| [Search] [Filter: All v] [Pause/Resume] | -+------------------------------------------+ -| 10:42:33 Chrome ads.google.com BLOCKED | <- red -| 10:42:32 Gmail smtp.gmail.com ALLOWED | <- green -| 10:42:31 Maps maps.google.com ALLOWED | <- green -| 10:42:30 Facebook graph.fb.com BLOCKED | <- red -| 10:42:28 System connectivity.. CACHED | <- blue -+------------------------------------------+ -``` - -- New entries animate in from top with slide + fade -- Auto-scroll pauses when user scrolls up (like terminal behavior) -- "Jump to latest" FAB appears when not at bottom -- Pause button freezes the stream for inspection without losing data - -### Diagnostic Report Generation - -Compile a shareable diagnostic report: - -``` -HostShield Diagnostic Report -============================ -App Version: 1.5.0 -Android Version: 14 (API 34) -Device: Pixel 8 Pro -VPN Status: Active -DNS Provider: Cloudflare DoH (1.1.1.1) -Uptime: 4d 12h 30m - -Stats (Last 24h): - Total Queries: 12,847 - Blocked: 3,241 (25.2%) - Avg Latency: 23ms - Cache Hit Rate: 42% - -Active Blocklists: 5 - - AdAway (45,232 rules) - - Steven Black Unified (87,124 rules) - ... - -Recent Errors: - [2026-03-25 09:15] DNS timeout to 1.1.1.1 (recovered) - ... - -Battery Usage: 2.1% over 24h -Memory: 45MB RSS - -[Sanitized logs attached: last 100 queries] -``` - -### Crash Reporting with ACRA - -**ACRA** (Application Crash Reports for Android) is the recommended open-source solution: - -- No proprietary dependencies, fully self-hosted -- Configurable user interaction: silent, toast, dialog, or notification -- Reports sent even if app doesn't crash (manual error reporting) -- Offline storage: reports queued and sent on next app start -- Backend options: **Acrarium** (official, active development) or custom HTTP endpoint -- Supports annotation-based configuration: `@AcraCore`, `@AcraMailSender`, `@AcraHttpSender` -- Integrates with 1.57% of all Play Store apps (13K+ apps, 5B+ downloads) - ---- - -## 7. Notification Systems - -### Block Notification Patterns - -**Recommended approach: Summary notifications** (not per-query) - -``` -Channel: "Blocking Activity" (user-configurable frequency) - -Option 1: Periodic Summary (default) - "HostShield blocked 342 requests in the last hour" - Expandable: top 5 blocked domains - -Option 2: Per-App Alerts - "Chrome tried to reach ads.doubleclick.net (blocked)" - Only for user-selected apps - -Option 3: Silent (log only) - No notifications, just dashboard stats -``` - -### Notification Channel Architecture - -``` -hostshield_protection_status (Foreground service - required, persistent) -hostshield_blocking_summary (Periodic block summaries - default: hourly) -hostshield_new_app_alert (New app detected accessing network) -hostshield_schedule_change (Profile auto-switched) -hostshield_update_available (App/blocklist updates) -hostshield_diagnostic (Errors, warnings, connectivity issues) -hostshield_backup (Backup completed/failed) -``` - -Best practices: -- Group channels using `NotificationChannelGroup` for clean Settings UI -- Default all non-essential channels to LOW importance -- Protection status channel: FOREGROUND_SERVICE importance (required by Android) -- Let users customize summary frequency: real-time / hourly / daily / off - -### Persistent VPN Notification Customization - -The system VPN notification cannot be fully hidden (Android enforces it), but: - -- **Customize the foreground service notification**: Show useful stats (queries blocked today, current DNS latency) -- **Include quick actions**: "Pause 30min", "Switch Profile", "View Log" -- **Use a network speed graph** in the notification (NetGuard Pro pattern) -- **Allow "Silent & Minimized"** guidance: Walk users through `Settings > Apps > HostShield > Notifications > VPN Status > Silent & Minimized` -- **Style with InboxStyle or BigTextStyle** to show expandable stats - ---- - -## 8. Potential New Features - -### 8.1 Family / Parental Controls - -Inspired by AdGuard DNS Family Protection and NextDNS: - -- **Age-based profiles**: "Young Child" (strict), "Teen" (moderate), "Adult" (custom) -- **Safe Search enforcement**: Force safe search on Google, Bing, DuckDuckGo, YouTube, Yandex, Brave, Ecosia (AdGuard's approach -- DNS-level enforcement) -- **20+ content categories**: Adult, Gambling, Social Media, Gaming, Streaming, etc. (AdGuard Home offers 20+ categories) -- **Time-based access**: Allow social media only 4-6 PM on weekdays -- **Activity reports**: Weekly email/notification summary for parents -- **PIN/biometric lock**: Prevent children from modifying settings - -### 8.2 Device Groups / Multi-Device Management - -Inspired by NextDNS and PowerDNS Protect: - -- Create device groups (e.g., "Kids Tablets", "Parents Phones", "IoT Devices") -- Apply different filtering profiles per group -- Central dashboard showing all devices (requires optional cloud component or LAN sync) -- For purely local: Use Android's Nearby Connections API to sync configs between household devices - -### 8.3 WireGuard / Proxy Integration - -Directly from RethinkDNS's proven architecture: - -- **Multiple WireGuard upstreams** in split-tunnel config -- **SOCKS5 and HTTP CONNECT proxy** support -- **Per-app routing**: Route specific apps through WireGuard, others direct -- **Multi-hop**: Chain WireGuard -> Tor for high-security needs -- UI: Visual tunnel diagram showing traffic flow per app - -### 8.4 Local DNS Server Mode - -- Run HostShield as a DNS server on the local network (not just local VPN) -- Other devices on the same Wi-Fi can point their DNS to the phone's IP -- Useful when HostShield runs on a dedicated old phone as a "portable Pi-hole" -- Implementation: Listen on port 53 (requires root) or high port (5353) with router port forwarding -- personalDNSfilter proves this works -- it can run as DNS proxy without VPN on rooted devices - -### 8.5 Split Tunneling - -From RethinkDNS (most advanced implementation): - -- Per-app VPN bypass (exclude banking apps, work apps) -- Per-app DNS override (use corporate DNS only for work apps) -- Per-app proxy routing (different WireGuard tunnels per app) -- Visual UI: App list with routing assignment dropdown - -### 8.6 App-Specific DNS Rules - -RethinkDNS's implementation to adopt: - -- Allow/deny specific domains per app -- Allow/deny specific domains globally -- Bypass DNS + firewall rules entirely per app -- IP-based rules per app -- Condition-based: block when app is in background, allow in foreground - -### 8.7 Encrypted DNS Stamp Support (`sdns://`) - -From DNSCrypt ecosystem: - -- Parse and generate `sdns://` stamps for one-click DNS server configuration -- Support stamp types: DNSCrypt, DoH, DoT, Anonymized DNSCrypt, ODoH (Oblivious DoH) -- QR code sharing of DNS stamps between devices -- Import from public resolver lists (e.g., dnscrypt.info/public-servers) -- Stamp calculator built into the app for advanced users - -### 8.8 Speed Test / DNS Benchmark Integration - -Open-source libraries available: - -- **JSpeedTest** (`bertrandmartel/speed-test-lib`): Java/Android speed test library using Ookla servers -- **LibreSpeed**: Fully open-source speed test (F-Droid available) -- **DNS benchmark**: Measure latency to multiple resolvers and recommend the fastest -- Show comparative results: "Cloudflare: 23ms, Google: 31ms, Quad9: 45ms" -- Auto-select fastest resolver option -- Periodic background benchmarks to alert if current resolver degrades - -### 8.9 Content Filtering Categories - -From AdGuard Home's category system: - -``` -Categories (toggleable per profile): - Ads & Trackers [ON] - Advertising networks, analytics - Malware & Phishing [ON] - Known malicious domains - Adult Content [OFF] - Pornography, explicit material - Gambling [OFF] - Betting, casino sites - Social Media [OFF] - Facebook, Instagram, TikTok, etc. - Gaming [OFF] - Online games, game stores - Streaming [OFF] - Netflix, YouTube, Twitch - Dating [OFF] - Dating apps and sites - Cryptocurrency [OFF] - Mining, exchanges - Piracy [OFF] - Torrent sites, illegal streaming - VPN & Proxy [OFF] - VPN/proxy bypass services - New Domains [OFF] - Recently registered (< 30 days) -``` - -### 8.10 Additional Feature Ideas - -- **CNAME cloaking detection**: personalDNSfilter has this -- resolve CNAME chains and block first-party tracking subdomains that CNAME to tracking servers -- **DNS-over-HTTP/3 (DoH3)**: Google added Android support in 2022 -- offer as an option for reduced latency -- **Oblivious DoH (ODoH)**: Route DNS through a relay for extra privacy (RethinkDNS supports this via relays) -- **Connection tracker**: Show real-time active connections per app with destination IP, port, protocol, data transferred (RethinkDNS's standout feature) -- **IP-based geolocation in logs**: Show country flags next to resolved IPs -- **Blocklist auto-update**: Schedule periodic blocklist refreshes via WorkManager - ---- - -## 9. Recommended Chart Library - -### Verdict: **Vico** (`patrykandpatrick/vico`) - -| Criteria | Vico | MPAndroidChart | YCharts | -|----------|------|----------------|---------| -| Compose native | Yes (also supports Views) | No (AndroidView interop) | Yes | -| Multiplatform | Yes (KMP) | No | No | -| Animation | Built-in, differences animated by default | Manual | Limited | -| Real-time updates | `ChartEntryModelProducer` API | Manual invalidation | Manual | -| M2/M3 theming | Optional Material integrations | None | Partial | -| Dependencies | Very few | Heavy | Moderate | -| Maintenance | Active (2025-2026 releases) | Stale | Moderate | -| Chart types | Line, Column, Combined | Line, Bar, Pie, Scatter, Radar, Bubble | Line, Bar, Pie, Donut | - -**Why Vico**: Native Compose support without interop hacks, real-time data update API, built-in animations, Material 3 integration, low dependency count, and active maintenance. Perfect for HostShield's dashboard charts (24-hour query volume, blocked percentage over time, latency graphs). - -**Alternative for Pie/Donut charts**: Vico does not support pie charts. Use `ehsannarmani/ComposeCharts` for the blocked-categories donut chart. - ---- - -## 10.

Dependency stabilization. + - Media3 1.10.1 is current. + - Compose BOM, Room, WorkManager, Hilt, ONNX Runtime, OkHttp, and Lottie have newer lines available. + - Kotlin and AGP latest metadata points at pre-release lines and should be handled intentionally. + +4. FFmpeg 16 KB and license decision. + - A future FFmpeg path unlocks concat demuxer, reverse export, libass subtitle burn-in, loudnorm, and mixed copy/re-encode. + - The decision must document GPL/LGPL flavor, F-Droid implications, ABI coverage, and Play Store 16 KB evidence. + +5.

The [Forward View](#forward-view--now--next--later--under-consideration--rejected-2026-05) at the end is the synthesis layer: every item from every round classified into Now / Next / Later / Under Consideration / Rejected with one-line justification. + +--- + +## Round 7 - Deep Research Consolidation (2026-05-17) + +Round 7 reconciled the live repository, local memory, project instructions, Maven metadata, official Android/Media3 docs, open-source editors, commercial mobile editors, model repositories, and dependency release streams. Full evidence and source notes live under [.ai/research/2026-05-17](.ai/research/2026-05-17/); canonical project memory now lives in [PROJECT_CONTEXT.md](PROJECT_CONTEXT.md). + +### R7.1 - Diagnostic export UI is the fastest trust win + +Local evidence: `app/src/main/java/com/novacut/editor/engine/DiagnosticExportEngine.kt`, `app/src/main/java/com/novacut/editor/ui/settings/SettingsViewModel.kt`, and `app/src/main/java/com/novacut/editor/ui/settings/SettingsScreen.kt` show that the diagnostic ZIP path is now a first-class Settings workflow. Competitor research showed that mature editors lean on export logs, reproducible diagnostics, and support bundles because media failures are device-, codec-, and source-file-specific. + +Done in the autonomous continuation after Round 7: Settings now exposes a "Diagnostic ZIP" row that explains the local-only bundle, creates the ZIP through `DiagnosticExportEngine`, stores it under `filesDir/diagnostics/`, shows busy/success/error states, and shares through `FileProvider` + `ACTION_SEND`. `file_paths.xml` grants only the diagnostics directory, and the engine keeps project files, media, captions, transcripts, and autosave JSON out of the bundle. This completes [R5.5d](#r55--observability--privacy-preserving-telemetry) without adding telemetry. + +### R7.2 - Model registry checksum closure before new model activation + +Local evidence: [docs/models.md](docs/models.md) still contains `SHA TBD` rows and model activation gates for Whisper, Moonshine, RVM, RIFE, Real-ESRGAN, SAM, Demucs, DeepFilterNet, and translation packs. The shipped `ModelDownloadManager` and offline/privacy posture are strong, but future PAD/on-demand model work should not proceed with unsigned or unpinned payloads. + +Implementation target: finish model SHA-256 pins, add metadata validation tests, document license/PAD/F-Droid track decisions per model, and make failed checksum states visible in the model-management UI before adding additional large model bundles. + +### R7.3 - Dependency stabilization train + +Maven metadata checked on 2026-05-17 found Media3 Transformer already current at 1.10.1, while Compose BOM, Room, WorkManager, Hilt, ONNX Runtime, OkHttp, and Lottie have newer release trains available. Kotlin and AGP latest metadata points at pre-release lines, so those should be handled as a deliberate toolchain branch rather than a blind bump. + +Implementation target: run one dependency train with release-note review, Gradle build/test verification, Android 16/16 KB native checks, and explicit rollback notes. Prioritize libraries that unblock shipped roadmap rows: Room/Work for background project/model jobs, ONNX Runtime for ML engines, Lottie for template parity, and OkHttp only after confirming 5.x API compatibility. + +### R7.4 - FFmpeg 16 KB and license decision gate + +Local evidence: the roadmap already moved A.9/B.3/B.5 toward `ffmpeg-kit-16kb`, while external evidence shows the original ffmpeg-kit upstream was archived and package distribution changed. This is an architectural and licensing decision, not only a dependency swap. + +Implementation target: choose and document the exact Maven coordinate, ABI coverage, GPL/LGPL build flavor posture, Play Store 16 KB evidence, F-Droid implications, and test matrix before wiring the concat demuxer, reverse export, libass burn-in, two-pass loudnorm, and mixed copy/re-encode stitching. + +### R7.5 - Media3 Lottie adoption experiment + +Media3 1.10.1 is already in tree, and Media3 has a first-party Lottie effect module. The local code still carries custom Lottie overlay/template engines. This is a small, reversible experiment with good cleanup potential. + +Implementation target: create a focused spike that renders the current overlapping Lottie cases with `media3-effect-lottie`, compares output/golden frames against the custom path, and either replaces the overlay effect or records the remaining blocker. + +### R7.6 - Documentation and instruction drift cleanup + +Local evidence: root `CLAUDE.md` and `.claude/CLAUDE.md` are local tool notes and are ignored by Git, but they still contain stale references such as older SDK, Media3, database, and line-count claims. [CROSS-PROJECT-ROADMAP.md](CROSS-PROJECT-ROADMAP.md) is useful as a backlog source but advertises an older current version. + +Implementation target: keep tool-specific files intact, but use [PROJECT_CONTEXT.md](PROJECT_CONTEXT.md) as the committed source of truth for current version, architecture, build commands, memory reconciliation, and handoff context. + +## Round 8 — Platform Deltas & Compliance Wave (2026-05-17) + +Round 8 follows the same-day Round 7 consolidation. Round 7 closed release-readiness gates that were already implied by the live repo (16 KB, model registry, dependency train, FFmpeg, Lottie spike). Round 8 extends with **platform deltas Round 7 didn't surface** — Android 15/16 mandatory behaviors that ship the moment we keep `targetSdk = 36`, plus genuinely new 2026 capabilities (M3 Expressive, C2PA, FTC/EU disclosure law, predictive back), plus form-factor and adjacent-app deltas. Every item is delta-only — anything already covered in Rounds 2-7 is referenced, not repeated. + +Detailed R8.N entries with evidence and implementation targets live in [§Research Round 8](#research-round-8--2026-05-17). The Forward View immediately below has been updated to integrate the Now/Next/Later items from this round. + +### Round 8 themes +- **Mandatory at `targetSdk = 36`** — edge-to-edge cannot opt out, predictive back is default-on, adaptive resizability applies on sw≥600dp. These are not "should do" — they ship the next time we re-publish. +- **2026 regulatory wave** — EU AI Act Article 50 effective 2026-08-02, FTC AI policy statement March 2026, federal "Protecting Consumers from Deceptive AI Act" April 2026. Three of NovaCut's roadmap items (R5.2d generative video, R6.18 lip-sync, A.12 cloud inpainting) become disclosure-bearing once they ship. +- **Provenance over telemetry** — C2PA Content Credentials are the strongest privacy-preserving trust signal NovaCut can ship. Pixel 10 already does it at Assurance Level 2; the c2pa-android library makes MP4 signing a one-engine integration. Pairs cleanly with `GenerativeVideoPolicy`. +- **Long-render reliability** — `ThermalManagerService.getThermalHeadroom(forecastSeconds)` is the single most under-used Android API for an editor. Throttling export when the SoC is hot turns "device shuts down at 78%" complaints into "render took 4 minutes longer." +- **Form-factor maturity** — Android 16 forces resizable+multi-window on sw≥600dp. NovaCut's panel-heavy editor needs an explicit large-screen pass before it lands on Pixel Fold / Pixel Tablet / Galaxy Z Fold / unfolded inner displays without UI clipping. + +## Forward View — Now / Next / Later / Under Consideration / Rejected (2026-05) + +This is the **prioritized synthesis** across all rounds. Every line maps back to an item ID elsewhere in this file (Tier A.N, B.N, C.N, R4.N, R5.N, R6.N, R7.N, or CROSS-PROJECT-ROADMAP §N) so traceability is one search away.

High viral ROI (isolate vocals for reaction cuts / acapellas). +- [ ] **C.2 — Silence & filler auto-cut** — Whisper already produces word timestamps; add a pass that proposes cut ranges for silences > configurable threshold and for filler words (um/uh/like/you know). v3.8 `cleanCaptionText()` only scrubs caption display — extend to cut clips. Touch: [ai/AiFeatures.kt](app/src/main/java/com/novacut/editor/ai/AiFeatures.kt), new `AutoCutSilencePanel.kt`. +- [ ] **C.3 — Voice cloning** — Sherpa-ONNX now ships XTTS v2 bindings (6-second enrollment sample, 16 languages). Pairs with A.8. New `VoiceCloneEngine.kt`, voiceover panel gains "Record 6s sample → clone" flow. +- [ ] **C.4 — AI lip-sync (Wav2Lip / SadTalker)** — ONNX models, lip-sync translated/dubbed voiceover to original speaker's face. Useful for C.5 translation workflow. Model ~300 MB (Wav2Lip GAN). +- [ ] **C.5 — Auto-translate captions** — NLLB-200 (200 langs) or MADLAD-400 via ONNX; translate Whisper output. Direct pair with existing caption pipeline. Model ~600 MB distilled / ~150 MB quantised. Touch: [ai/AiFeatures.kt](app/src/main/java/com/novacut/editor/ai/AiFeatures.kt), Caption panel gains language chip. +- [x] **C.6 — Audio mastering presets** — After A.2 + existing EBU R128: one-tap "Podcast voice / Music master / Dialogue clean / ASMR" chains (EQ + comp + limiter + denoise pre-configured). *(Done — [AudioMasteringEngine](app/src/main/java/com/novacut/editor/engine/AudioMasteringEngine.kt) already ships the 5 preset recipes (Podcast Voice, Music Master, Dialogue Clean, ASMR, Social Loud). This pass wires them end-to-end: new `buildEffectChain(preset)` converts a `MasteringChain` into the ordered HighPass → ParametricEQ → De-esser → Compressor → Limiter `AudioEffect` list; `AudioMixerDelegate.applyMasteringPreset(trackId, presetId)` replaces the track's audio effect chain in a single saveUndoState/refreshPreview/saveProject pass and is constructor-injected with the engine. 6 new tests in `AudioMasteringEngineTest` cover stage ordering, conditional skips, EQ-slot zero-fill, de-esser threshold scaling, limiter ceiling, and compressor param round-trip.)* + +### Media & assets +- [ ] **C.7 — Stock asset library** — Pexels + Pixabay (video + photo) + Freesound (SFX) + Free Music Archive (music) API tabs in MediaPicker. Each needs license compliance (attribution strings cached per asset). Touch: [ui/mediapicker/MediaPickerSheet.kt](app/src/main/java/com/novacut/editor/ui/mediapicker/). +- [ ] **C.8 — In-app camera with teleprompter** — `CameraX` capture, drop directly into timeline, optional scrolling teleprompter overlay while recording voiceover. Closes "record → edit → export" loop without leaving the app. New `ui/capture/` package. +- [x] **C.9 — HDR10 / Dolby Vision export** — Done in v3.74.2 for capable devices. `EncoderCapabilityProbe` now walks advertised HDR profiles for HEVC, AV1, VP9, and AV1-based Dolby Vision Profile 10; `ExportSheet` surfaces HDR10+, Dolby Vision Profile 10, encoder limits, and device-tier hardware encode hints before render. +- [ ] **C.10 — 360 / VR equirectangular editing** — Spherical navigation preview (yaw/pitch/roll gestures), equirectangular-aware crop and transitions. Target Insta360 / GoPro Max footage. New `effect/EquirectangularEffect.kt`, pose metadata passthrough via spatial media (XMP GPano). + +### Timeline & composition +- [ ] **C.11 — Adjustment layers** — First-class layer that applies effects to every clip beneath it across its time range. New `AdjustmentLayer` model, EffectBuilder applies via an overlay GL pass. Pro-NLE staple. Touch: [model/Track.kt](app/src/main/java/com/novacut/editor/model/), [engine/EffectBuilder.kt](app/src/main/java/com/novacut/editor/engine/EffectBuilder.kt). +- [ ] **C.12 — Keyframe graph editor** — Bezier curve editor UI for animated values. `KeyframeEngine` already supports 12 easings; missing the visual editor (two-handle bezier per segment, value scrubber, tangent lock). Touch: new `ui/editor/KeyframeGraphPanel.kt`. +- [ ] **C.13 — Nested sequences / compound clip UI** — `createCompoundClip()` exists in the model (v3.7 fix set `sourceDurationMs = compoundDurationMs`). Missing: tap compound to open sub-timeline, edit children, exit back. Touch: [ui/editor/EditorScreen.kt](app/src/main/java/com/novacut/editor/ui/editor/), new `CompoundClipEditor.kt`. + +### Interop & distribution +- [ ] **C.14 — NLE round-trip import** — Export to OTIO/FCPXML/EDL exists; build the inverse. Parse FCPXML → map to NovaCut tracks/clips/transitions, best-effort handling of Resolve-specific metadata. Touch: [engine/TimelineExchangeEngine.kt](app/src/main/java/com/novacut/editor/engine/TimelineExchangeEngine.kt). +- [ ] **C.15 — Template marketplace hub** — `.novacut-template` format exists (v3.8 export/import + share intent). Missing: discovery UI, self-hostable registry (e.g. GitHub Releases as backing store), rating/search. Touch: new `ui/templates/MarketplaceScreen.kt`. +- [ ] **C.16 — Cross-device project sync** — Syncthing-style (filesystem only) or Git-style (project history with diffs) for project JSON + media refs. Project archive (ZIP) already exists — extend with rsync-like delta and conflict resolution UI. + +--- + +## Delivery Notes + +### Sequencing guidance +1. **Do A before B/C when possible** — many Tier B/C items depend on Tier A engines. B.3 unblocks once A.9 ships; C.3 pairs with A.8; C.5 pairs with existing Whisper; C.6 composes A.2 + EBU R128. +2. **One Tier A + one Tier C per release cycle** keeps scope disciplined — avoid landing multiple new model downloads per release (app-install-size creep). +3. **Gate all model downloads behind explicit user action** — Android Play policies around on-device model auto-download remain touchy. Current pattern (user taps feature → "download 15 MB model?" prompt) is correct; keep it. + +### Dependency risk notes +- **A.3 OpenCV** — arm64 only; either ship arm64-only APK split or accept ABI filter. Never ship universal OpenCV (APK bloats past Play Store 150 MB limit). +- **A.9 FFmpegX-Android** — replaces archived ffmpeg-kit. Mehmet Genç (mzgs) maintains; verify active maintenance before pinning. +- **A.6/C.5 large models** — RVM and NLLB both push past typical mobile expectations. Consider quantised variants first (MADLAD-400 3B Q4 is ~1.5 GB; distilled NLLB is ~600 MB; smaller variants trade quality for install size). +- **C.4 Wav2Lip** — some model weights have non-commercial licenses; audit before shipping. + +### Architecture touch points common across multiple items +- Model download manager — today each engine open-codes its download. Consolidate to a `ModelDownloadManager` singleton with shared progress UI / retry / integrity check before shipping more on-device ML. +- Stub UX pattern — engines not yet integrated return a "This feature requires a model download" toast.

Real swap-in for `SherpaAsrEngine.kt` stub; copy `OnlineRecognizer.kt`/`OfflineRecognizer.kt` + the `jniLibs` ABI-filter block from build.gradle. +- **k2-fsa/sherpa-onnx/c-api-examples/whisper-c-api.c** — https://github.com/k2-fsa/sherpa-onnx/blob/master/c-api-examples/whisper-c-api.c — canonical config: encoder + decoder ONNX + `tokens.txt`. Matches the Whisper release-asset triplet (`sherpa-onnx-whisper-tiny.tar.bz2`). +- **gl-transitions/gl-transitions** — https://github.com/gl-transitions/gl-transitions — 80+ GLSL transition shaders. Spec requires `getFromColor(uv)` / `getToColor(uv)`; wrap in a shim so upstream shaders compile unchanged against NovaCut's 2-texture sampler. +- **transitive-bullshit/ffmpeg-gl-transition/vf_gltransition.c** — https://github.com/transitive-bullshit/ffmpeg-gl-transition/blob/master/vf_gltransition.c — reference port feeding two frames to one GLSL program. Exit path from the mid-gray blend-mode workaround. +- **KaleyraVideo/AndroidDeepFilterNet** — https://github.com/KaleyraVideo/AndroidDeepFilterNet — Maven artifact + JNI wrapper. Minimum wiring: `implementation("com.kaleyra:deepfilternet-android:VERSION")` + `DeepFilterNet.process(pcm48k)`. Sample shows 480-sample frame size at 48kHz. +- **nihui/rife-ncnn-vulkan** — https://github.com/nihui/rife-ncnn-vulkan — Android-ready NCNN+Vulkan build of RIFE v4.6. Ship `librife.so` + model bin/param pair; replace `FrameInterpolationEngine` stub `Log.d` with `System.loadLibrary("rife")` + JNI `interpolate(prev, next, timestep)`. +- **advimman/lama** — https://github.com/advimman/lama — LaMa checkpoints + Qualcomm AI Hub ONNX export (big-lama.onnx). Maps to `InpaintingEngine.kt`; switch to QNN EP when device supports it. + +### Known Pitfalls from Similar Projects +- **Media3 shader diverges between GLSurfaceView preview and Transformer export** — androidx/media#1080 — Transformer feeds sRGB-linearized textures; preview path was gamma-encoded. Always sample via `getFromColor` helper or pre-apply gamma in the fragment shader. https://github.com/androidx/media/issues/1080 +- **Transformer multi-item transitions unsupported beyond crossfade** — androidx/media#1662 — Composition API supports only crossfade. Wipe/slide require overlapping clips on separate sequences and blending via a custom effect chain. https://github.com/androidx/media/issues/1662 +- **gl-transitions Android bundling unresolved** — gl-transitions#129 — no native-library ship; NovaCut will always be string-literal shaders, plan disk/assets storage + SHA validation accordingly. https://github.com/gl-transitions/gl-transitions/issues/129 +- **Sherpa-ONNX APK bloat** — the official Android AAR is ~54MB before model downloads, and Whisper/Moonshine model bundles can add 30–100MB each. Use ABI splits + Play Asset Delivery before enabling the native backend in base release builds. See release assets such as `sherpa-onnx-1.13.2.aar`. https://github.com/k2-fsa/sherpa-onnx/releases +- **ffmpeg-kit archived in 2025** — upstream stopped publishing. FFmpegEngine stub notes FFmpegX-Android (mzgs) — verify activity before pinning. https://github.com/arthenica/ffmpeg-kit +- **RIFE NCNN VRAM spikes on 1080p mid-range Adreno** — tile-based processing required; use `-t 256` tile size on devices with <6GB RAM or hit `VK_ERROR_OUT_OF_DEVICE_MEMORY`. https://github.com/nihui/rife-ncnn-vulkan/issues +- **LaMa NNAPI delegates silently fall back to CPU on Samsung Exynos** — probe `NnApiDelegate.Options.setAcceleratorName("google-edgetpu")` first, bail to `XnnPackDelegate`. https://github.com/advimman/lama/issues +- **OpenTimelineIO Java bindings arm64-only** — bundling for x86 emulators requires x86_64 JNI which is not shipped. Gate OTIO export on `Build.SUPPORTED_ABIS.contains("arm64-v8a")`. https://github.com/AcademySoftwareFoundation/OpenTimelineIO +- **MediaCodec AV1 encoder availability lies** — `MediaCodecList` reports the encoder but init fails with `MediaCodec.CodecException`. Try-open + close at preset-apply time, not at export start. https://github.com/androidx/media +- **`EditedMediaItemSequence(list)` constructor deprecation continues at 1.9.2** — only the Builder is future-proof. https://github.com/androidx/media + +### Library Integration Checklist +- **Sherpa-ONNX (Kotlin ASR)** — target GitHub asset `sherpa-onnx-1.13.2.aar` until an official Maven Central coordinate is published. Entry remains `OfflineRecognizer(config).decode(samples, sampleRate).text`. Gotcha: constructor requires model component file paths; ship via explicit model download + first-run extraction because ONNX Runtime cannot read zipped Android assets directly. +- **gl-transitions (80+ transitions)** — no package; vendor shaders into `app/src/main/assets/transitions/*.glsl`. Entry: build a shim header defining `getFromColor(uv) = texture(uFrom, uv)` + `getToColor(uv) = texture(uTo, uv)` and prepend to each shader at load time. Gotcha: some transitions declare `uniform float ratio`; default it to the clip aspect or the shader divide-by-zeros. +- **AndroidDeepFilterNet** — `com.kaleyra:deepfilternet-android:` (verify on Sonatype; artifact has moved) — entry: `DeepFilterNet.init(context)` then `process(FloatArray 480 samples @ 48kHz)`. Gotcha: fixed 48kHz; NovaCut's 16kHz Whisper path must resample to 48k then back — do it once per export, not per frame. +- **RIFE NCNN+Vulkan** — ship `librife.so` + `rife-v4.6/flownet.param` + `flownet.bin` in `jniLibs/arm64-v8a/` and `assets/models/rife/`. Entry: JNI `nativeInterpolate(prev: Bitmap, next: Bitmap, timestep: Float): Bitmap`. Gotcha: Vulkan device init must happen off the main thread; wrap the first call in `withContext(Dispatchers.Default)` or the ANR watchdog fires on cold start. +- **LaMa ONNX** — self-host `big-lama-int8.onnx` (~55MB) on GitHub Release asset; fetch on first use. Entry: `OrtSession(big-lama.onnx).run(mapOf("image" to imageTensor, "mask" to maskTensor))`. Gotcha: model expects 512×512 fixed input — tile-and-blend for higher res; mask channel must be `{0,1}` not `{0,255}`. + +## Research Round 4 — Capability Benchmarks to Push NovaCut Beyond Mobile NLEs + +Research date: 2026-04-25. Scope: complementary open-source projects, professional editor benchmarks, media-engine standards, and AI/video research that can make NovaCut more capable, stronger, more versatile, and more differentiated. Treat this as product and architecture direction, not a promise to add every dependency directly. + +### Executive synthesis +- [ ] **R4.1 — Make timeline interchange a core capability, not an export add-on.** OpenTimelineIO proves that timelines, clips, gaps, transitions, adapters, and media references can become a stable interchange model. NovaCut already has OTIO/FCPXML/EDL export ambitions; the next leap is import, validation, round-trip tests, conflict diagnostics, and a "repair timeline" tool. Touch: `TimelineExchangeEngine.kt`, `TimelineImportEngine.kt`, `ProjectArchive.kt`. +- [ ] **R4.2 — Add a studio-grade color/HDR backbone.** OpenColorIO, ACES, and libplacebo point to a serious color roadmap: named working spaces, display transforms, LUT management, HDR-to-SDR tone mapping, gamut warnings, preview/export parity, and export metadata sanity checks. Touch: `ColorGradingPanel.kt`, `LutEngine.kt`, `HdrCapabilityProbe.kt`, `VideoEngine.kt`, `ExportService.kt`. +- [x] **R4.3 — Shift from clip editing to object-aware editing.** First binding pass complete: tracked objects can now drive a clip-level Tracked Mosaic effect in preview/export, the effect persists its target ID, and the Effects panel exposes mosaic actions for tracked masks on the selected clip. Remaining object-aware expansion lives in follow-up items: tracker generation, sticker/text attach, selective grading, crop/reframe, and object removal. Touch: `TrackedObject.kt`, `TrackedObjectEffectBinding.kt`, `EffectBuilder.kt`, `ShaderEffect.kt`, `VideoEngine.kt`. +- [ ] **R4.4 — Add gyro/lens metadata stabilization as a premium differentiator.** Gyroflow shows that stabilization becomes meaningfully better when camera gyro, accelerometer, lens profile, rolling-shutter, and sync data are first-class inputs instead of only frame-difference heuristics. Touch: `StabilizationEngine.kt`, `MediaImportEngine.kt`, new `GyroMetadataParser.kt`. +- [ ] **R4.5 — Build a creator-first auto-edit assistant.** Auto-Editor, Premiere text-based editing, and CapCut auto captions/templates point to one workflow: transcript + silence + filler + beat + face/object salience should produce an editable rough cut, not a one-way render. Touch: `AiFeatures.kt`, `EditorViewModel.kt`, new `AutoCutReviewPanel.kt`. +- [ ] **R4.6 — Introduce a live source / scene graph mode.** OBS's scene/source/filter model is not a traditional NLE feature, but it is powerful for creators. NovaCut can combine CameraX, screen capture, mic sources, layouts, and reusable scenes so recording and editing happen in one product. Touch: `CameraCaptureEngine.kt`, `MediaPickerSheet.kt`, new `LiveStudioPanel.kt`. +- [ ] **R4.7 — Add an advanced compositor graph without making the core editor harder.** Natron, Blender, GStreamer Editing Services, and Olive all argue for a graph/layer model for expert workflows. NovaCut should keep the default editor simple, then expose an optional "Advanced Composite" panel for nodes, adjustment layers, masks, and nested sequences. Touch: `EffectBuilder.kt`, `KeyframeEngine.kt`, `model/Track.kt`. +- [ ] **R4.8 — Treat templates as programmable products.** Remotion, Glaxnimate, Lottie, Rive, and CapCut templates suggest a stronger template format: typed slots, brand tokens, motion presets, caption styles, data-driven variants, preview thumbnails, and compatibility checks before import. Touch: `TemplateManager.kt`, `TemplateMarketplaceEngine.kt`, `LottieTemplateEngine.kt`. +- [ ] **R4.9 — Add professional project confidence tools.** Blender/Pitivi/GES and OTIO point to diagnostics users trust: missing media, broken time ranges, unsupported effects, proxy/original mismatch, color-space mismatch, model missing, export incompatibility, and "what will change on export" reports. +- [ ] **R4.10 — Keep dependency gates strict.** Every research item needs license review, binary-size budget, offline/privacy behavior, device capability probe, fallback path, and deterministic tests before it graduates from roadmap to implementation. + +### Project and benchmark findings + +| Project / benchmark | What to study | NovaCut opportunity | Priority | Source | +|---|---|---|---|---| +| **OpenTimelineIO** | Stable editorial timeline model, media references, adapters, plugin architecture, FCP XML / AAF / EDL ecosystem | Make OTIO the canonical import/export/validation layer;

Interchange-native pro workflow +- [ ] Add `TimelineImportEngine` support for OTIO/FCPXML/EDL with a visible import report: missing media, unsupported transitions, substituted effects, timecode drift, frame-rate conversions, and color-space assumptions. +- [ ] Add `TimelineExchangeValidator` that runs before export and produces a user-readable compatibility report instead of silently dropping unsupported data. +- [ ] Add golden round-trip fixtures: NovaCut project → OTIO/FCPXML/EDL → NovaCut project should preserve clip order, trim ranges, transitions, markers, text/caption tracks, and media references where possible. +- [ ] Add "archive repair" mode to `ProjectArchive.importArchive()`: remap missing URIs, detect duplicate project IDs, migrate older schema versions, and let the user choose merge vs duplicate. + +#### 2. Studio color, scopes, and HDR confidence +- [ ] Add project color settings: source interpretation, working space, display transform, output transform, and LUT stack order. +- [ ] Add a color mismatch warning when preview, source metadata, and export metadata disagree. +- [ ] Add HDR/SDR export preview chips: "HDR preserved", "HDR tone-mapped to SDR", "metadata copied", "metadata rewritten", or "metadata unavailable". +- [ ] Add scopes beyond histogram: waveform, vectorscope, RGB parade, and highlight clipping overlay. +- [ ] Add 3D LUT management: import `.cube`, show source/provenance, preview before/after, and warn when a LUT is applied in the wrong color space. + +#### 3. Object-aware editing layer +- [ ] Add a reusable `TrackedObject` model with stable ID, label, confidence, mask path, bounding box path, keyframes, and source engine metadata. +- [ ] Let captions, stickers, blur, mosaic, crop windows, color effects, and audio focus bind to a `TrackedObject`. +- [ ] Add "Select subject once" flow: tap object → refine mask → track through clip → review drift points → apply operation. +- [ ] Add fallback tiers: MediaPipe live task first, then SAM 2 / MobileSAM model download, then manual mask/keyframes if model is unavailable. +- [ ] Add privacy copy for AI tools: on-device by default, cloud only when explicitly selected, with data-retention text in the confirmation sheet. + +#### 4. Gyro and lens-aware stabilization +- [ ] Add metadata import for GoPro/Insta360/DJI/Sony gyro streams where available, plus sidecar support for Gyroflow project/protobuf data. +- [ ] Add lens profile selection and auto-detection UI during import. +- [ ] Add stabilization preview metrics: crop required, horizon lock availability, rolling-shutter correction availability, and confidence. +- [ ] Keep optical-flow stabilization as fallback when no gyro metadata exists. + +#### 5. Cut Assistant and transcript-first editing +- [ ] Build a non-destructive "Review proposed cuts" panel instead of auto-mutating the timeline. +- [ ] Combine transcript words, silence, filler words, speaker changes, beat detection, motion/salience, and manual protected ranges. +- [ ] Let users accept/reject each proposed cut, ripple the timeline, or create a new rough-cut sequence. +- [ ] Preserve source transcript and sequence transcript separately so users can rough-cut from text and still generate final captions later. + +#### 6. Live Studio mode +- [ ] Add a scene/source graph: camera, screen capture, image, video, text, browser/web overlay if supported, mic, and system audio where Android allows it. +- [ ] Add reusable source filters: crop, chroma key, denoise, gain, compressor, LUT, blur, background replace. +- [ ] Add "Record to timeline" so a live scene becomes a clip with editable source metadata and scene layout. +- [ ] Add creator presets: podcast split screen, reaction layout, tutorial camera-over-screen, product demo, livestream intro/outro. + +#### 7. Programmable template platform +- [ ] Extend `.novacut-template` with typed slots: media, text, logo, color token, music, caption style, duration, aspect ratio, safe-area rules. +- [ ] Add compatibility checks before import: required engines, model downloads, fonts, aspect ratio support, and license metadata. +- [ ] Add brand kit integration: logo, palette, caption style, type scale, default lower-third, watermark, and platform safe areas. +- [ ] Add template preview rendering with placeholder media and cached thumbnails. +- [ ] Add a self-hostable registry format backed by static JSON/GitHub Releases so the marketplace is not locked to a proprietary server. + +### Architecture and implementation guardrails +- **Do not add heavyweight native dependencies blindly.** Several projects are desktop-first or Python/C++ heavy. Borrow architecture and UX patterns first; only embed native code after Android feasibility, ABI size, license, and maintenance checks. +- **Keep model downloads explicit.** SAM 2, Depth Anything, YOLO, ASR, matting, and inpainting models must use a shared `ModelDownloadManager` with size disclosure, checksum verification, retry, Wi-Fi-only setting, and remove-model controls. +- **Keep privacy visible.** AI and cloud paths need a predictable on-device/cloud label, confirmation sheet, and failure fallback. Premium trust depends on users knowing where their media goes. +- **Design every advanced feature with a beginner-safe default.** Advanced graph, color, and interchange tools should not clutter the first-run editor. Use progressive disclosure: simple panel first, expert controls behind "Advanced". +- **Add diagnostics before adding more effects.** Missing media, dropped tracks, unsupported codecs, unsupported effects, model absence, and color/HDR mismatch should be shown before export begins. +- **Use test fixtures for every interchange and repair path.** Roadmap items touching OTIO/FCPXML/EDL/archive import should ship with malformed input, missing media, duplicate ID, old schema, mixed frame-rate, and unsupported-effect fixtures. +- **Prefer reversible operations.** Auto-cutting, object removal, stabilization, reframing, and template application should create editable operations/layers rather than destructive timeline mutations. +- **Budget for device tiers.** Every AI/video feature needs at least three paths: premium acceleration path, mid-device reduced-resolution/tiled path, and no-model/manual fallback path. + +### Suggested sequencing +1. **Foundation release:** OTIO/FCPXML/EDL import reports, project archive repair, shared model download manager, and export diagnostics. +2. **Trust release:** color/HDR preview/export parity, scopes, LUT provenance, and metadata warnings. +3. **Creator speed release:** Cut Assistant, transcript-first rough cut, caption style presets, and creator onboarding format picker. +4. **Object-aware release:** tracked object model, MediaPipe task bridge, SAM 2 optional path, tracked stickers/blur/crop. +5. **Motion/template release:** programmable template schema, brand kit, Lottie/Rive validation, vector motion editor concepts. +6. **Studio release:** Live Studio mode, scene/source graph, CameraX/screen capture insertion, OBS-style source filters. +7. **Pro finishing release:** gyro/lens stabilization, advanced compositor graph, OpenFX-like effect descriptors, ACES-inspired color preset. + +### Highest-leverage next tickets +- [x] Implement `TimelineExchangeValidator` and run it before every export/import. *(v3.70.0 — wired ahead of `exportToOtio` / `exportToFcpxml`; categorised report drives the result toast.)* +- [x] Complete `ProjectArchive.importArchive()` with media remap, migration, duplicate-ID handling, and recovery copy. *(v3.70.0 — new `importArchiveWithReport()` returns schema/version/media-resolution diagnostics; `IdCollisionPolicy.REGENERATE` default; legacy entry point preserved.)* +- [x] Add shared `ModelDownloadManager` with checksum, retry, Wi-Fi-only, and remove-model controls. *(v3.70.0 — `sha256` per file, `wifiOnly`/`isMeteredNetwork()`, `removeModel`/`removeModels`/`installedBytes`; existing callers source-compatible.)* +- [x] Add Cut Assistant review UI using existing Whisper word timestamps plus silence detection. *(Post-v3.71 pass — added AI Hub / AI toolbar entry plus a review sheet with selected-by-default proposals, accept/reject all, per-proposal toggles, time ranges, reclaimed-duration summary, empty state, and one undoable apply action. Borrowed the comparable Descript / Premiere / CapCut pattern of surfacing detected filler words and pauses for review before bulk deletion.)* +- [x] Add `TrackedObject` model and bind one operation first: tracked blur or tracked sticker. *(Post-v3.71 continuation — Tracked Mosaic now binds `TrackedObject` keyframes to a Media3 shader mask, persists target IDs through autosave/archive, and exposes a selected-clip action in the Effects panel.)* +- [x] Add color/HDR export confidence chips and mismatch warnings. *(Post-v3.71 continuation — ExportSheet now surfaces a Preserve HDR Metadata toggle, Color / HDR confidence chips, codec/device mismatch warnings, HDR10+ dynamic metadata support status, and advertised HDR encode limit warnings. Pure `ExportColorConfidenceEngine` covers SDR, H.264 HDR mismatch, missing HDR support, HDR10+ support, and limit-overrun cases.)* +- [x] Add template compatibility metadata and import validation before marketplace work. *(Post-v3.71 continuation — template exports now include schema/app-version/required-feature metadata plus slot counts; imports infer + merge legacy metadata, reject future schemas/versions/unknown required features before saving, and show clearer failure copy.)* + +--- + +## Research Round 5 — 2026 Refresh + +Research date: 2026-05. Scope: refresh Tier A/B unblocks against current upstream releases, identify successor dependencies for archived ones, and surface coverage gaps the previous rounds left thin (accessibility, i18n, observability, distribution, plugin ecosystem, security). Treat as a delta on top of Rounds 2–4 — items already covered are not repeated. + +### R5.1 — Media3 1.10 unblocks Tier B.1/B.2/C.9 +Media3 1.10 (March 2026) ships the multi-sequence/multi-track Composition API, wider Dolby Vision / HDR handling, and VVC ingest. This is a direct dependency bump that retires the longest-standing limitation in this roadmap. +- [x] **R5.1a — Bump `androidx.media3` from 1.9.2 → 1.10.x** in [app/build.gradle.kts](app/build.gradle.kts). Done in v3.74.0 with Media3 1.10.0 across ExoPlayer / Transformer / Effect / Common / UI / Muxer, then lifted to 1.10.1 in v3.74.2 for the AV1-based Dolby Vision handling fix. Audit confirmed `VideoEngine` and `ProxyEngine` already use `EditedMediaItemSequence.Builder`, so no removed list-constructor migration was needed. Sources: https://github.com/androidx/media/releases · https://developer.android.com/media/media3/transformer/composition +- [x] **R5.1b — Wire multi-sequence Composition into `VideoEngine`** — Done in v3.74.1. `VideoEngine` now exports one sequence per visible visual track, preserves per-track mute/solo/volume semantics for embedded audio, appends dedicated audio-track sequences, and disables embedded-audio transmuxing when multiple visual sequences require compositing. `VideoEngine` and `ProxyEngine` builders now use explicit Media3 track types. Upstream issue #1662 is closed as of 2025-09-09, so NovaCut keeps the existing wipe/slide effect-chain workaround until a dedicated transition migration is implemented. +- [x] **R5.1c — Enable Dolby Vision Profile 10 + HDR10+ export paths** in `EncoderCapabilityProbe` (closes C.9 on capable devices). Done in v3.74.2. The probe now classifies HDR10, HDR10+, and AV1-based Dolby Vision Profile 10 profiles; ExportSheet shows Color / HDR confidence plus a capability-derived Standard / Advanced / Premium device tier. Pixel 10 / Tensor G5-style AV1 + VP9 hardware encode is detected from actual encoders rather than hard-coded model names. Sources: https://developer.android.com/media/media3/transformer/supported-formats · https://developer.android.com/reference/android/media/MediaCodecInfo.CodecProfileLevel · https://www.androidauthority.com/pixel-10-video-recording-av1-vp9-3586429/ +- [x] **R5.1d — Android 15/16 Ultra HDR ingest** — Done in v3.74.3. `MediaImportEngine` now records source color metadata for imported clips, classifies video HDR10 / HDR10+ / HLG / Dolby Vision from `MediaFormat`, detects Android Ultra HDR gain-map still images via `Bitmap.hasGainmap()` on Android 14+, persists the metadata in autosave, and feeds source HDR / Ultra HDR chips into ExportSheet confidence. Sources: https://developer.android.com/media/grow/ultra-hdr · https://source.android.com/docs/core/display/hdr + +### R5.2 — Dependency successor pivots +- [~] **R5.2a — Pin `salahawad/ffmpeg-kit-community` instead of FFmpegX-Android (A.9).** Blocked in v3.74.4 after re-checking the successor fork: the GitHub project is public and active, but exposes no releases/tags yet, and Maven Central does not currently expose a pinnable `ffmpeg-kit-community` artifact. Do not add an unversioned JitPack dependency for release builds; re-evaluate when the fork publishes a stable tag/AAR coordinate, keeping FFmpegX-Android (mzgs) as the secondary candidate. **Superseded by [R6.5](#r65--ffmpeg-kit-16kb-supersedes-r52a-block)** — `com.moizhassan.ffmpeg:ffmpeg-kit-16kb:6.1.1` is now published on Maven Central, is 16 KB page-size aligned for Android 15+, and is the recommended A.9 pin going forward. Sources: https://github.com/arthenica/ffmpeg-kit · https://github.com/salahawad/ffmpeg-kit-community · https://libraries.io/maven/com.moizhassan.ffmpeg:ffmpeg-kit-16kb +- [x] **R5.2b — Upgrade Sherpa-ONNX target to v1.12.28+ for Moonshine v2 (A.1).** Done in v3.74.5. `SherpaAsrEngine` now targets Sherpa-ONNX v1.13.2, records the official Android AAR asset URL, and codifies the target model policy: Moonshine v2 Tiny as the default English ASR target and Whisper Tiny multilingual as the non-English fallback. Runtime activation still stays under A.1 because the official project currently ships Android AARs as GitHub release assets rather than a normal Maven Central coordinate, so NovaCut should not silently vendor the native payload into the base app. Source: https://github.com/k2-fsa/sherpa-onnx/releases +- [x] **R5.2c — SAM 2.1 ONNX path now viable for tracked masks (R4.3 follow-up).** Done in v3.74.6. `TapSegmentEngine` now records SAM 2.1 Hiera Tiny ONNX as the default tracked-mask target, preserves MobileSAM as the smaller fallback, and exposes a tested device-gating policy that only recommends SAM 2.1 when premium model downloads are allowed and available RAM meets the >200 MB working-set requirement. Runtime activation remains under A.7 because the model must still be an explicit download. Sources: https://github.com/facebookresearch/sam2 · https://huggingface.co/onnx-community/sam2.1-hiera-tiny-ONNX +- [x] **R5.2d — Generative video stays cloud-optional, not on-device.** Done in v3.74.7. Added `GenerativeVideoPolicy` so Wan 2.2, HunyuanVideo, and VideoCrafter2-class providers are represented only as optional cloud effects, never bundled on-device engines. The policy requires destination, upload-size, retention, and explicit-consent disclosure before a future cloud render can start, with tests preventing accidental on-device bundling. Sources: https://github.com/Wan-Video/Wan2.2 · https://github.com/Tencent-Hunyuan/HunyuanVideo · https://github.com/AILab-CVC/VideoCrafter + +### R5.3 — Accessibility coverage gap +- [x] **R5.3a — TalkBack semantics for the timeline custom view.** Done in v3.74.4. Custom-drawn clip nodes now expose richer Compose semantics with clip name/type/track/duration/start-time descriptions, selected and locked-track state, and `customActions` for split, delete, nudge earlier, and nudge later. Accessibility split actions select the clip and move the playhead to a valid split point when needed before reusing the existing split operation. Source: https://developer.android.com/jetpack/compose/accessibility +- [x] **R5.3b — Switch Access + keyboard-only editing flow.** Done in v3.74.8. Visible timeline clips are now focusable nodes with keyboard handling for select, split, delete, and left/right nudge. Focused clips use 100 ms arrow nudges, Shift+arrow uses 1 second nudges, and trim mode maps the same focused arrows to slip edits. The editor shell also supports Shift+arrow selected-clip nudging so hardware keyboards and Switch Access can move a clip without touch. +- [x] **R5.3c — Caption style accessibility presets.** Done in v3.74.9. Caption Style Gallery now has a dedicated accessible preset section with WCAG-AA high-contrast fill/background/stroke templates, a large-text preset above the 24sp 1080p floor, and a reduced-motion preset that maps to static subtitle rendering with no word-by-word or animated caption style. Applying a caption template now carries font, fill, background, highlight, position, outline color/width, shadow, and style-type intent into actual caption data, with autosave preserving the new stroke fields. +- [ ] **R5.3d — Closed audio description track export.** Already in §Backlog. Promote to Round 5 because `SDH / audio-description` text export shipped in v3.69 — the audio track itself is the missing piece. Use TTS engine (A.8) to render the audio-description text into a sidecar or muxed AD track on export. + +### R5.4 — Internationalization / localization +- [~] **R5.4a — Caption translation pipeline (C.5) gains in-editor preview.** Beyond the model dependency, the edit UX needs side-by-side source/target caption rows and a per-caption "regenerate" action. *(In progress — data model shipped: [CaptionTranslationEngine](app/src/main/java/com/novacut/editor/engine/CaptionTranslationEngine.kt) gains `EditorRowState` (TRANSLATED / USER_EDITED / REGENERATE_PENDING), `LanguagePairQuality` (Excellent / Good / Fair / Experimental / Unknown), and `TranslatedSegment.editorState`. New `pairQuality(variant, src, tgt)` is a pure function the panel can probe before model download. New `BERGAMOT_PER_PAIR` model variant per R6.7. MADLAD count bumped 400 → 419 to match R6.7 documentation. 12 new tests. Compose panel rendering follows in a UI commit.)* +- [ ] **R5.4b — RTL timeline + overlay bidi text.** Already in §Backlog as "RTL / bidirectional text in overlays". Promote: timeline ruler direction, transition arrows, and the trim-handle hit zones must mirror under RTL locales. Source: https://developer.android.com/training/basics/supporting-devices/languages#BidirectionalText +- [x] **R5.4c — Strings extraction audit.** *(Done — audit performed 2026-05-16. The Round 5 claim "Many engine stubs emit user-facing copy via `Log.d` / `Toast.makeText`" was incorrect for the current codebase: engines have **zero** `Toast.makeText` or `Snackbar.make` calls. `Log.d` / `Log.w` / `Log.e` output is internal/diagnostic and not subject to localization. The only English-only surfaces in the engine package today are structured diagnostic message fields on result records: `ProjectArchive.errorMessage` (4 strings), `TemplateCompatibility.message` (3), `TimelineExchangeValidator.message` (26). Those carry their own routing story (dialog/report rendering, not toasts) and are tracked as a separate localization workstream rather than via this one-time pass. Added `EngineStringExtractionAuditTest` which fails the build if any engine ever calls `Toast.makeText` or `Snackbar.make` directly — that lane stays closed.)* +- [~] **R5.4d — Locale-aware caption font fallback.** *(In progress — policy layer shipped: [CaptionFontFallbackPolicy](app/src/main/java/com/novacut/editor/engine/CaptionFontFallbackPolicy.kt) maps BCP-47 / ISO-639-1 language tags to the recommended Noto subset family (SC / TC / JP / KR / Arabic / Hebrew / Devanagari / Bengali / Tamil / Thai). Locale-region-aware (zh-Hant → TC, zh-Hans → SC). `totalBundleBytes()` + `rendersWithSystemFontsOnly()` surface per-language disclosure data for the Settings UI. 17 new tests cover every supported language, case insensitivity, and unknown-language fallback. Actual Noto bundle install + renderer integration follows in a UI commit; bundling Noto CJK alone is ~20 MB per writing system so distribution lives behind Play Asset Delivery (R5.6a).)* + +### R5.5 — Observability / privacy-preserving telemetry +- [ ] **R5.5a — Opt-in crash reporting via Sentry-Android.** Strict opt-in dialog at first run, settings toggle, redaction of all media URIs and project paths from breadcrumbs. Initialize the SDK only when the user opts in. Source: https://docs.sentry.io/platforms/android/ +- [ ] **R5.5b — Aggregate-only usage metrics via Mozilla Glean or a Divvi-Up-style aggregator.** Goal: know which engines actually get used so future stub-activation work targets the most-used features. No raw events, no identifiers. Sources: https://mozilla.github.io/glean/book/language-bindings/android/index.html · https://divviup.org/blog/horizontal-tella/ +- [~] **R5.5c — Privacy dashboard.** *(In progress — data model shipped at [PrivacyDashboard](app/src/main/java/com/novacut/editor/engine/PrivacyDashboard.kt). Single source of truth for every category NovaCut collects: project content, media metadata, ML models, app preferences, template library, diagnostic logs, cloud generative video, opt-in telemetry. Each entry records storage location, controls (export/delete/opt-out), collecting engines, retention policy, and default-collection state. 10 invariant tests lock the contract: every category has a delete action, cloud/telemetry rows are never on by default, entries match the Category enum 1:1. Compose dashboard panel rendering follows in a UI commit; the data layer is ready to consume.)* +- [x] **R5.5d — Local-only diagnostic export.** A "Save diagnostic ZIP" action in settings (logcat tail, project header, model registry, Media3 capabilities snapshot) so users can attach to a GitHub issue without us shipping any telemetry pipe. *(Done — engine layer ships via [DiagnosticExportEngine](app/src/main/java/com/novacut/editor/engine/DiagnosticExportEngine.kt), and Settings now exposes the flow through [SettingsViewModel](app/src/main/java/com/novacut/editor/ui/settings/SettingsViewModel.kt) + [SettingsScreen](app/src/main/java/com/novacut/editor/ui/settings/SettingsScreen.kt). Writes a ZIP under `filesDir/diagnostics/` with 6 entries: app-info, device-info, media-codecs (MediaCodecList.REGULAR_CODECS summary), model-registry (id + install state + size, no file contents), logcat-tail (last 200 lines, redacted), and manifest. Sensitive substrings — content://, file://, /storage/, /data/data/, URLs with query strings, email addresses — are scrubbed before write. Project JSON, media URIs, autosave snapshots, captions/transcripts are **never included** by design. Self-prunes past 3 ZIPs. `file_paths.xml` grants FileProvider access only to `filesDir/diagnostics/`, and the UI shows local save/share plus busy, success, and error states. 8 tests in `DiagnosticExportEngineTest` cover the redaction filter and the bundle structure contract.)* + +### R5.6 — Distribution and packaging +- [ ] **R5.6a — Play Asset Delivery for ML model bundles.** Whisper, Moonshine, RVM, RIFE, Real-ESRGAN, MobileSAM, Demucs all together blow past the 200 MB base-AAB. PAD on-demand asset packs, keyed off the existing `ModelDownloadManager`, are the correct vector — keeps F-Droid track buildable while Play install stays small. Source: https://developer.android.com/guide/playcore/asset-delivery +- [~] **R5.6b — F-Droid track with NonFreeNet anti-feature audit.** Any model fetched from a non-free CDN (Hugging Face is OK; vendor-locked endpoints are not) triggers `NonFreeNet`. Document each model URL + license + checksum in [docs/models.md](docs/models.md) so reproducible-build maintainers can verify. *(In progress — [docs/models.md](docs/models.md) now records every active model and AAR with source URL, license, and `NonFreeNet` posture for known source domains; SHA-256 columns flagged ⚠ TBD must be filled before each Tier A engine activates per R5.9b.)* Source: https://f-droid.org/docs/Anti-Features/ +- [ ] **R5.6c — Reproducible release builds.** F-Droid inclusion requires byte-identical AAB rebuilds. Pin Gradle, AGP, Kotlin, and JDK in `gradle.properties`; commit the lockfile. +- [ ] **R5.6d — APK split by ABI for OpenCV / NCNN / ONNX.** OpenCV (A.3) is arm64-only at ~40 MB. NCNN (A.4 RIFE) and ONNX Runtime add more. ABI splits + universal-fallback policy on GitHub Releases (arm64 primary, armv7 trimmed, x86_64 emulator-only). + +### R5.7 — Plugin ecosystem +- [x] **R5.7a — Promote `.novacut-template` to first-class plugin format.** *(Done — [PluginRegistry](app/src/main/java/com/novacut/editor/engine/PluginRegistry.kt) now classifies `.novacut-template`, `.ncfx`, `.ncstyle`, `.cube`, `.3dl`, and `.ncfxd` under one share-intent + import surface. Longest-extension-first detection so `.ncfxd` wins over `.ncfx` false-positive. 10 new tests.)* +- [x] **R5.7b — OpenFX-style effect descriptor (read-only).** *(Done — [OpenFxDescriptor](app/src/main/java/com/novacut/editor/engine/OpenFxDescriptor.kt) defines the `.ncfxd` JSON schema and parser. Carries `novaCutEffectId`, `openfxId`, per-parameter `(novaCutName, openfxName, range, scale, offset, type)` mapping with `toOpenFx`/`fromOpenFx` round-trip math. Permissive parser skips invalid parameter entries instead of failing the whole file. 10 new tests cover conversion math, round-trip, schema version gate, malformed-input rejection, inverted-range skipping.)* +- [x] **R5.7c — Glaxnimate / Rive / Lottie compatibility matrix.** *(Done — [docs/templates.md](docs/templates.md) covers the plugin format family, the round-trip compatibility matrix for Lottie / dotLottie / Rive / Glaxnimate, the kind-driven validation pipeline, license hygiene rules, and reproducibility hooks. Lottie 7.x state-machine path documented as the recommended dotLottie target; A.13 Rive parking decision recorded.)* + +### R5.8 — Testing strategy (when explicitly requested) +*Not auto-executed — listed here so it is on the page when next requested.* +- Roborazzi screenshot tests for every panel (caption, trim, keyframe graph, ExportSheet) — golden images per device tier. +- Espresso flow: import → cut → caption → export. One per major engine activation in Tier A. +- Test fixtures called out in §Architecture guardrails (line 282) — malformed FCPXML, missing media, schema-too-new, mixed frame rate — already in scope; add per-fixture asserts when the request lands. + +### R5.9 — Security and supply chain +- [x] **R5.9a — Track Media3 + ONNX Runtime CVE feeds.** *(Done — [.github/dependabot.yml](.github/dependabot.yml) watches both Gradle (with grouped PRs for Media3, Compose, AndroidX core, Hilt, ML, Kotlin, Coil) and GitHub Actions. One weekly PR per ecosystem keeps the inbox manageable on a single-maintainer project.)* Source: https://nvd.nist.gov/ +- [x] **R5.9b — Model checksum enforcement at runtime.** *(Done — `ModelDownloadManager.isValidModelFile()` gains a `requireChecksum: Boolean = false` parameter; new public `verifyChecksumOrDelete(file, minimumBytes, expectedSha256)` is the first-run verification entry point. When `requireChecksum = true`, a null SHA-256 is a **failure** (not a silent pass-through) — callers loading distribution-critical models pass true so a missing registry entry blocks the load instead of trusting the bytes. Mismatched files are deleted; missing-hash files are kept on disk so a later SHA-256 fill in docs/models.md validates without a re-download. 4 new tests in `ModelDownloadManagerTest`.)* +- [ ] **R5.9c — Cloud effect call-out sheet.** Any cloud-touching path (C.7 stock, C.4 Wav2Lip cloud variant, R5.2d generative video) shows a one-time "this will leave your device" sheet with the destination, payload size, and an opt-out toggle stored per project. +- [ ] **R5.9d — Sign release artifacts.** Already done for AAB/APK via Play. Add `cosign` signatures to GitHub Release artifacts so users sideloading the APK can verify provenance.

Scope: changes since the Round 5 cut on 2026-05-14 that materially affect Tier A/B/C sequencing — primarily the 16 KB Play Store gate, the LiteRT migration, the Gemini Nano on-device LLM surface, a concrete ffmpeg-kit successor, SAM 3 / SAM 3.1, and Whisper Turbo. Delta-only: anything already covered in Rounds 2–5 is not repeated. Every item below maps into a tier in the [Forward View](#forward-view--now--next--later--under-consideration--rejected-2026-05) at the top. + +### R6.1 — 16 KB page-size compliance (Play Store gate) + +Google Play requires 16 KB page-size alignment for all new apps and updates targeting Android 15 (API 35) and higher since 2025-11-01. NovaCut ships with `targetSdk = 36`, so this is a **blocking** constraint, not a future one. The compliance check fires at Play Console upload time, not at runtime. Any bundled native code (ONNX Runtime, MediaPipe Tasks, future NCNN / OpenCV / Sherpa-ONNX / DeepFilterNet / RIFE / Real-ESRGAN AAR payloads) must be NDK r28+ compiled. + +- [x] **R6.1a — Audit every bundled `.so` for 16 KB alignment.** *(Done — [scripts/check_16kb_alignment.py](scripts/check_16kb_alignment.py) is a pure-Python ELF parser that walks a directory tree, APK, or AAB and flags any PT_LOAD segment whose alignment is < 0x4000 on arm64-v8a / x86_64 / riscv64. CI workflow [.github/workflows/build.yml](.github/workflows/build.yml) now runs the script over the merged release native libs after `assembleRelease` and fails the build on misalignment.)* +- [x] **R6.1b — Pin NDK r28+ in `gradle.properties`.** *(Done — `gradle.properties` now carries the NDK r28+ pin instructions with the correct AGP block syntax. NovaCut's `:app` currently has no project-side native code, so the pin lives as a comment ready to copy into the `android { }` block when A.4 (NCNN RIFE) or any other project-side native code lands.)* +- [x] **R6.1c — Document the alignment status in [docs/models.md](docs/models.md).** *(Done — initial registry created at [docs/models.md](docs/models.md) with §2 "Native AARs — 16 KB compliance gates" tracking ORT, MediaPipe, ffmpeg-kit-16kb, Sherpa-ONNX, DeepFilterNet, RIFE, OpenCV. R6.1a verification commands documented inline.

The replacement is LiteRT (TensorFlow Lite successor) with the CompiledModel API. NovaCut's [`InpaintingEngine.kt`](app/src/main/java/com/novacut/editor/engine/InpaintingEngine.kt) still references NNAPI in its docstring as the recommended execution provider — this is now misleading. + +- [x] **R6.2a — Strip NNAPI guidance from `InpaintingEngine` docs**; document the ONNX Runtime + XNNPACK/QNN/CoreML EP path as primary, with the LiteRT CompiledModel API as the future TFLite-backed alternative. *(Done — docstring rewritten and the `addNnapi()` call removed from `SessionOptions`. Default CPU EP is used until per-EP capability probing lands. The Tier A InpaintingEngine activation path is unchanged.)* +- [ ] **R6.2b — Audit segmentation / MediaPipe TFLite path** ([`SegmentationEngine.kt`](app/src/main/java/com/novacut/editor/engine/segmentation/SegmentationEngine.kt)) — when MediaPipe Tasks Vision upgrades its internal TFLite to LiteRT, no NovaCut change is needed.

These run on-device via AICore on devices with ≥12 GB RAM and a supported NPU. This is the first time NovaCut can plausibly add a *user-facing* LLM feature without breaking the on-device-by-default privacy stance. + +- [ ] **R6.3a — Gated AI Hub card: "Smart Suggestions (Pixel 10 / 12 GB RAM)"** that surfaces device capability and a one-time consent sheet before any Gemini Nano call. +- [ ] **R6.3b — Use cases (in priority order):** + - Image Description for accessibility — auto-generate spoken audio-description text for a clip range (pair with R5.3d AD track export). + - Project Summarization — natural-language "what's in this project" for the project list, generated from clip names + caption text. + - Caption Style Suggestions — rewrite caption text for tone presets (Reels Hook, Tutorial Voice, ASMR Whisper) without leaving the device. + - Template Pick — given the clip set + transcript, suggest the best `.novacut-template`. +- [ ] **R6.3c — Hard fallback policy:** no GenAI call ever blocks an edit operation. All paths must no-op on non-Pixel-10 / pre-Nano devices. +- [ ] **R6.3d — Never call cloud Gemini from this codepath** — the entire feature is `media3-gen-on-device-only`. Cloud generative work continues to live under `GenerativeVideoPolicy` (R5.2d).

SAM 3.1 (Mar 2026) adds object multiplexing (16 objects per forward pass; doubles video throughput). Combined model is 848M parameters and is currently only feasible on H100-class GPUs. + +- **Decision for now:** keep the SAM 2.1 Hiera Tiny default policy shipped in v3.74.6 ([`TapSegmentEngine.kt`](app/src/main/java/com/novacut/editor/engine/TapSegmentEngine.kt)). Do *not* promote SAM 3 / 3.1 to the recommended target until an ONNX-export Tiny variant exists with realistic mobile memory characteristics. +- [x] **R6.4a — Add a `SAM3_HIERA_TINY_ONNX` `ModelVariant` placeholder** with `requiresPremiumTier = true` and `supportsVideoPropagation = true`, gated behind a feature flag that defaults off until upstream ships the export. *(Done — [TapSegmentEngine](app/src/main/java/com/novacut/editor/engine/TapSegmentEngine.kt) now carries `ModelFamily.SAM3` and the `SAM3_HIERA_TINY_ONNX_PLACEHOLDER` enum row with placeholder size estimates (240 MB model, 128 MB state cache, 8 GB RAM floor). `recommendedModelForDevice()` is gated on `SAM3_PLACEHOLDER_ENABLED` (currently false) so the policy default remains SAM 2.1. Tests lock the gate.)* +- [x] **R6.4b — Add a "text prompt → mask" stub method** on `TapSegmentEngine` that delegates to SAM 3 when available; until then, falls back to `MediaPipe.detect()` + bbox → SAM 2.1 mask. Closes the API shape early so the eventual SAM 3 swap is one-line. *(Done — `segmentByTextPrompt(bitmap, textPrompt)` returns null today with an explicit "concept-segmentation unavailable" log. When SAM 3 ships an ONNX export, only the `SAM3` branch needs an implementation; callers don't change.)* Sources: https://ai.meta.com/blog/segment-anything-model-3/ · https://github.com/facebookresearch/sam3 · https://arxiv.org/abs/2511.16719 + +### R6.5 — `ffmpeg-kit-16kb` supersedes R5.2a block + +The R5.2a R&D pass blocked on "no pinnable Maven artifact for ffmpeg-kit successor". As of 2026, `moizhassankh/ffmpeg-kit-android-16KB` publishes to Maven Central as `com.moizhassan.ffmpeg:ffmpeg-kit-16kb:6.1.1`, is 16 KB aligned for Android 15+, and is built with NDK r27d, Full-GPL, and MediaCodec support — the exact wiring [`FFmpegEngine.kt`](app/src/main/java/com/novacut/editor/engine/FFmpegEngine.kt) expects. + +- [~] **R6.5a — Pin `com.moizhassan.ffmpeg:ffmpeg-kit-16kb:6.1.1`** in [gradle/libs.versions.toml](gradle/libs.versions.toml) and replace the `FFmpegEngine` stub `execute()` body with the `FFmpegKitConfig.executeAsync` bridge. *(In progress — [FFmpegEngine](app/src/main/java/com/novacut/editor/engine/FFmpegEngine.kt) now documents the activation path explicitly in its class docstring (catalog entry, build.gradle.kts line, license obligation). `isAvailable()` now does a reflection probe so the rest of the system can branch on FFmpeg presence the moment the dep is added — no recompile needed of consumers. Bridging the stub method bodies to `FFmpegKit.executeAsync` lands when the dep itself is wired.)* +- [ ] **R6.5b — Unblocks downstream:** B.3 reverse playback in export (`filter_complex` `[0:v]reverse[v]`), libass subtitle burn-in (replaces shipped Canvas path on demand), two-pass `loudnorm` filter, sidechain compress ducking, AV1 software-encode fallback on devices without hardware AV1. +- [ ] **R6.5c — GPL note:** `ffmpeg-kit-16kb` is the Full-GPL build. NovaCut is MIT-licensed; bundling a GPL `.so` does not relicense Kotlin source under GPL but does require shipping the LGPL/GPL notice + offer-of-source per FFmpeg's license. Document in [LICENSE](LICENSE) addendum before shipping. (LGPL-only variant exists if we want to dodge the obligation, at the cost of losing libx264/libx265/libfdk — accept H.264/HEVC via MediaCodec only.)

This is a pure model-bump. + +- [x] **R6.6a — When A.2 activates, target DeepFilterNet 3 model weights** (not v2). *(Done — [NoiseReductionEngine](app/src/main/java/com/novacut/editor/engine/NoiseReductionEngine.kt) class docstring now codifies the DeepFilterNet 3 target (PESQ 3.5–4.0+, ~8 MB, same JNI as v2) and the companion object exports `TARGET_MODEL_VERSION = "3"` constants for telemetry and diagnostic surfaces. Activation note documents the model-bytes swap pattern via `ModelDownloadManager` if the AAR still bundles v2.

The 2026 mobile-translation landscape has moved: RTranslator 3 (NGI Mobifree grant, beta Apr–Jun 2026) is replacing NLLB-200 with **MADLAD-400 3B** (419 languages, mobile-quantizable) and **Mozilla Bergamot** (Firefox's offline translation models). Quality benchmarks beat NLLB 54B in their target language pairs. + +- [ ] **R6.7a — Re-target C.5 caption translation to MADLAD-400 + Bergamot.** NLLB-200 distilled remains the fallback for languages neither MADLAD nor Bergamot covers well. +- [ ] **R6.7b — In-editor preview UX (already in R5.4a):** side-by-side source/target caption rows, per-caption regenerate action, per-language quality chip.

Whisper Large V3 Turbo (4-decoder-layer ONNX) is now the practical multilingual upgrade: ONNX Runtime + Arm KleidiAI delivers ~2.6× faster inference on Android than the Tiny baseline, with substantially better WER. Sherpa-ONNX v1.13.2 already includes the bindings. + +- [x] **R6.8a — Document a three-target policy** in `SherpaAsrEngine` model metadata: Moonshine v2 Tiny (English, fastest), Whisper Tiny (multilingual, smallest), Whisper Large V3 Turbo (multilingual, premium accuracy). *(Done — [SherpaAsrEngine](app/src/main/java/com/novacut/editor/engine/whisper/SherpaAsrEngine.kt) ModelVariant now carries `isMultilingual`, `requiresPremiumTier`, and `minimumRamMb` fields. `WHISPER_LARGE_V3_TURBO_MULTILINGUAL` joins the enum as the third target with `sizeMb = 800`, `requiresPremiumTier = true`, `minimumRamMb = 6_144`.)* +- [x] **R6.8b — Gate Turbo on the same premium-tier rule** used for SAM 2.1 (≥6 GB RAM + premium-models-allowed setting). The 4-layer-decoder ONNX is still a heavier download than Tiny. *(Done — `preferredModelFor(language, allowPremiumModels, availableRamMb)` evaluates English-first, then for non-English routes Turbo only when both the user setting and RAM floor are met; otherwise falls back to Whisper Tiny multilingual. Five new tests in `SherpaAsrEngineTest` lock the policy: English ignores premium, multilingual without premium → Tiny, multilingual with premium but low RAM → Tiny, multilingual with premium + ≥6 GB → Turbo, plus metadata assertions on the new enum entry.)* Sources: https://huggingface.co/onnx-community/whisper-large-v3-turbo · https://aihub.qualcomm.com/mobile/models/whisper_large_v3_turbo · https://onnxruntime.ai/blogs · https://github.com/k2-fsa/sherpa-onnx/releases + +### R6.9 — Gyroflow project file import for R4.4 + +R4.4 (gyro/lens-aware stabilization) scopes a from-scratch gyro pipeline. The pragmatic first step is *not* to reimplement: Gyroflow already ships on Google Play, accepts gyro/lens data from GoPro / Sony / DJI / Insta360 / many phones, and writes a `.gyroflow` project file describing the stabilization decisions. NovaCut can accept that file as a sidecar on import, apply the resulting affine + per-frame crop, and skip the whole gyro-math layer entirely. + +- [ ] **R6.9a — Add `.gyroflow` sidecar detection** in `MediaImportEngine`. If a sibling file with the same basename exists, parse the JSON (Gyroflow's format is open) and store the resulting per-frame transforms on the imported clip. +- [ ] **R6.9b — Apply Gyroflow transforms during preview/export** via `MatrixTransformation` (already used for clip transforms). Crop ratio surfaced in the stabilization panel. +- [ ] **R6.9c — Full gyro-math reimplementation deferred** to a future round; the sidecar import covers ~80% of the creator value with ~10% of the engineering cost.

NovaCut's custom impl carries all three; the official module's 1.10.x surface needs to be audited before the dep flip.)* +- [ ] **R6.10b — Evaluate `media3-ui-compose-material3` Player Composable** to replace bespoke `PreviewPanel` controls. Risk: the new Composable's gesture model differs from our trim-aware preview — likely keep custom for now, but document the parity gap. +- [ ] **R6.10c — Track the `media3-inspector-frame` migration** (the old `FrameExtractor` moved out of `media3-inspector` in 1.10).

Pre-flight `validateDestination(protocol, url)` and `recommendedBitrateBps(w, h, fps)` are pure functions the UI can use today. 11 new tests.)* +- [ ] **R6.17b — Compose against `CameraCaptureEngine`** (already stubbed) once R4.6 lands so a live scene can be sent direct from the scene graph. *(Waits on R4.6 Live Studio scene graph.)* +- [ ] **R6.17c — Adaptive bitrate** mirrors the Larix pattern: probe network, scale resolution + framerate downward, never block the encoder thread. *(Documented as a hard requirement in the engine class docstring; implementation lands with the chosen streaming library.)* Sources: https://softvelum.com/larix/ · https://play.google.com/store/apps/details?id=com.wmspanel.larix_broadcaster + +### R6.18 — MuseTalk / LatentSync supersede Wav2Lip for C.4 + +C.4 (AI lip-sync) was scoped against Wav2Lip. The 2026 quality bar has moved: MuseTalk and LatentSync (diffusion-based, latent-space) produce near-photorealistic results where Wav2Lip's GAN artifacts are visible. Wav2Lip retains the cost crown (3-min video → 5–15 min compute on cloud GPU), but quality demand pushes new work toward MuseTalk / LatentSync. + +- [ ] **R6.18a — Pivot C.4's target to MuseTalk (primary) / LatentSync (high-quality variant)** and document Wav2Lip as the legacy fallback. +- [ ] **R6.18b — Cloud-only path enforced via shipped `GenerativeVideoPolicy`** (R5.2d). No on-device bundling — all three models are far too heavy. +- [ ] **R6.18c — License audit:** Wav2Lip has non-commercial weights for some checkpoints; MuseTalk is CC-BY-NC; LatentSync uses Stable Diffusion derivatives. Document license per provider in `GenerativeVideoPolicy` provider metadata before any consent sheet ships.

As of 2026, libplacebo is the de-facto HDR tone-mapper for mpv/VLC/FFmpeg with dynamic HDR, Dolby Vision Profile 5 conversion, perceptual gamut stretching, debanding, contrast recovery. Vulkan-first, no Android port — embedding is not practical. + +- [ ] **R6.19a — Borrow the algorithm design** (specifically the HDR→SDR display transform with measurement + dynamic exposure) for NovaCut's HDR confidence path. Today we report capability; tomorrow we should report *quality estimate* (banding risk, clipping risk). +- [ ] **R6.19b — Do not embed libplacebo** — Vulkan-only and desktop-first. Borrow patterns into pure GLSL ES 3.0 shaders consistent with the existing 37-transition pipeline.

Architecture: Next.js web + Rust core (GPU compositor + effects + masks via WASM) + early GPUI desktop. **Android story is thin** — no concrete Android target. + +- **Watch, don't port.** The Rust GPU compositor is conceptually exciting (could inspire B.2's programmable dual-texture blend) but porting Rust via NDK to coexist with Media3 is a multi-quarter engineering effort with unclear ROI given NovaCut's Kotlin-first stack. +- [ ] **R6.20a — Track OpenCut's Android proof of concept** if one materializes. No code action yet.

The open enhancement issues are revealing: + +| Their open ask | NovaCut status | +|---|---| +| Timeline (#48) | ✅ Multi-track with thumbs, waveforms, snap, markers, color labels | +| Keyframes for filters (#47) | ✅ KeyframeEngine + 12 easings + bezier editor (graph editor pending — C.12) | +| Image layer support (#24) | ✅ Sticker/GIF/image overlays with position/scale/rotate/opacity | +| Face blurring (#31) | ✅ Tracked Mosaic (post-v3.71) | +| Pitch audio controls (#46) | ✅ Pitch shift in AudioEffectsEngine | +| Audio-video muxing (#37) | ✅ Multi-sequence Media3 Composition (v3.74.1) | +| Rotate quick buttons (#57) | ✅ Crop panel + transform rotation | +| Opus audio support (#35) | ✅ Via Media3 ExoPlayer; MediaPicker launcher now accepts `application/ogg` alongside `audio/*` and the resolver MIME check + extension probe both recognise `.opus` (R6.21 verified). | +| RGB alpha adjustment (#39) | ✅ Color grading + blend modes | + +**Takeaway:** NovaCut is *meaningfully ahead* of the only direct OSS Android NLE on every published community ask. The community signal is not "what to add" but "differentiate harder on the polished UX of features you already have."

Android Firewalls - -### 1.1 NetGuard - -| Field | Detail | -|-------|--------| -| **GitHub** | https://github.com/M66B/NetGuard | -| **Stars** | ~3,530 | -| **License** | GPL-3.0 | -| **Language** | Java + C (native VPN) | - -**Architecture:** -- Uses `VpnService` to create a local TUN interface -- all device traffic is routed through it. -- Core logic lives in `ServiceSinkhole.java` (extends `VpnService`). -- Native C layer (`netguard.c`) performs actual packet inspection and forwarding in the TUN read/write loop. -- When an app is blocked, packets are "sinkholed" -- dropped silently with no remote server involved. - -**Per-App Network Access Control:** -- Each app listed with separate toggles for Wi-Fi and Mobile Data. -- Allowed/blocked state stored per UID; the native layer matches outgoing packets to UIDs via `/proc/net` and the kernel's UID-based routing. - -**Foreground vs Background:** -- Android restricts apps from seeing which other apps are in the foreground (post-Android 10 privacy changes). -- NetGuard works around this with a **"screen on/off" condition** rather than true foreground detection. When screen is off, background rules apply; when screen is on, foreground rules apply. This is automatic and avoids the Accessibility Service requirement. - -**Wi-Fi vs Mobile Data Differentiation:** -- Distinct allow/block columns for Wi-Fi and mobile data per app. -- Handles **metered Wi-Fi** as a separate category (configurable in Network Settings > "Handle Metered WiFi Networks"). - -**LAN/Localhost Access:** -- Subnet routing configurable in network settings. -- Tethering support available. -- Localhost traffic generally not intercepted (VPN TUN interface only sees routed traffic). - -**Metered Network Rules:** -- Built-in metered Wi-Fi detection; applies mobile-data rules to metered Wi-Fi connections when enabled. - -**Key Takeaway for HostShield:** NetGuard's screen-on/off approach for fg/bg detection is pragmatic and avoids Accessibility Service permission. The sinkhole pattern (drop packets in native C) is highly efficient. - ---- - -### 1.2 AFWall+ - -| Field | Detail | -|-------|--------| -| **GitHub** | https://github.com/ukanth/afwall | -| **Stars** | ~3,320 | -| **License** | GPL-3.0 | -| **Language** | Java | - -**Architecture:** -- **Requires root.** Directly manipulates Linux `iptables` / `ip6tables` rules. -- Rules are applied at the kernel netfilter level -- far lower than VPN-based solutions. -- Generates iptables chain rules per UID with `-m owner --uid-owner `. - -**Per-App Network Access Control:** -- Separate columns: Wi-Fi, Mobile Data (2G/3G/4G/5G), Roaming, VPN, Tethering, LAN. -- Most granular per-app control of any open source Android firewall. - -**Foreground vs Background:** -- Not explicitly differentiated at the iptables level; however, rules persist regardless of app state, effectively blocking all background traffic for denied apps. - -**Wi-Fi vs Mobile Data:** -- Fully independent rulesets per network type per app. -- Roaming treated as a separate network type. - -**LAN/Localhost:** -- Dedicated LAN toggle per app -- can allow local network while blocking internet. -- Localhost traffic controllable via iptables OUTPUT chain. - -**Metered Network:** -- No built-in metered detection; relies on Android's own metered network classification. - -**Key Takeaway for HostShield:** AFWall+'s per-app LAN toggle is a feature worth replicating. The separate Roaming column is excellent UX. For non-root devices, these rules must be approximated in the VPN layer. - ---- - -### 1.3 RethinkDNS (Rethink: DNS + Firewall + VPN) - -| Field | Detail | -|-------|--------| -| **GitHub** | https://github.com/celzero/rethink-app | -| **Stars** | ~4,700 | -| **License** | Apache-2.0 | -| **Language** | Kotlin + Go (native firestack) | - -**Architecture:** -- VPN-based, no root. Network stack (`firestack`) is a hard fork of Jigsaw-Code/outline-go-tun2socks written in Go. -- DNS filtering at the VPN layer: blocked domains get empty responses. -- Split-tunnel architecture: DNS queries trapped at VPN DNS endpoint, relayed to user-chosen DoH / DoT / DNSCrypt / ODoH resolver. - -**Per-App Network Access Control:** -- Block/allow entire apps. -- **Domain-per-app rules**: allow or deny specific domains for specific apps (unique feature). -- Category-based blocking: block all "Social" or "Games" apps using Play Store categories. -- User-defined denylists. -- IP-based firewall rules (editable). - -**Foreground vs Background:** -- Uses **Accessibility Service** to detect foreground/background app state. -- Rules can trigger on: screen-on/screen-off, app-foreground/app-background. - -**Wi-Fi vs Mobile (Metered vs Unmetered):** -- Rules differentiate **metered vs unmetered connections** rather than Wi-Fi vs mobile. -- This is arguably more correct since Wi-Fi can be metered and mobile can be unmetered. - -**LAN/Localhost:** -- Not prominently featured; DNS-layer blocking does not affect LAN-only traffic. - -**Proxy Support:** -- WireGuard, SOCKS5, HTTP CONNECT proxy tunnels. -- Per-app split tunneling: route different apps over different tunnels. - -**Connection Tracker:** -- Built-in per-app connection log: when connections were made, how many, to where. -- Flags suspicious/unknown connections. - -**Key Takeaway for HostShield:** RethinkDNS's domain-per-app rules and metered/unmetered distinction are best-in-class. The category-based blocking (Social, Games, etc.) is excellent UX. The Go-based network stack is worth studying for performance. - ---- - -### 1.4 LostNet NoRoot Firewall - -| Field | Detail | -|-------|--------| -| **Availability** | Closed source (Play Store / Amazon) | -| **Stars** | N/A (not on GitHub) | - -**Notable Features:** -- VPN-based, no root. -- **Country-based blocking**: block/unblock access to specific countries per app -- GeoIP integrated. -- **Per-country data usage monitoring** per app. -- Background activity restriction: block apps from internet access while backgrounded. -- Built-in **packet sniffer** with CloudShark.org export (Wireshark compatible). -- Instant notifications when blocked apps attempt connections or when apps try to reach blocked countries. - -**Key Takeaway for HostShield:** LostNet's country-based blocking with GeoIP is a compelling feature. The per-country usage monitoring is unique and valuable for privacy-conscious users. - ---- - -### 1.5 ShizuWall (Shizuku-based) - -| Field | Detail | -|-------|--------| -| **GitHub** | https://github.com/AhmetCanArslan/ShizuWall | -| **Stars** | ~1,290 | - -**Notable:** Uses Shizuku framework instead of VPN -- avoids the single-VPN limitation. Lightweight, no VPN conflict. Worth watching as an alternative approach. - ---- - -### 1.6 NoRoot Firewall - -| Field | Detail | -|-------|--------| -| **Availability** | Play Store (closed source) | - -**Features:** -- VPN-based, per-app Wi-Fi and mobile data toggles. -- Advanced domain/IP/hostname filter rules with import/export. -- Simple UI focused on accessibility. - ---- - -## 2. Network Traffic Monitoring & Stats - -### 2.1 Approaches Compared - -| Approach | Pros | Cons | -|----------|------|------| -| **NetworkStatsManager** (API 23+) | Official API; per-UID, per-network-type, time-bounded; no VPN needed; battery efficient | Requires `READ_PHONE_STATE` or carrier privileges for mobile stats; data delayed (not real-time); 2-hour bucket minimum | -| **TrafficStats** | Simple API; real-time cumulative bytes | Resets on boot; no per-time-range; unreliable per-UID on Android N+ | -| **VPN Packet Counting** | Real-time; per-connection granularity; works on all apps | Requires active VPN; battery cost; can't run alongside other VPNs | -| **/proc/net Parsing** | No special permissions on older Android; real-time | Restricted on Android 10+ (SELinux); fragile; platform-dependent | - -### 2.2 Best Practices for HostShield - -- **Primary**: Use `NetworkStatsManager` for historical per-app bandwidth with `queryDetailsForUid()`. Provides WiFi vs mobile breakdown, time-bounded queries, and survives reboots. -- **Real-time overlay**: When VPN is active, count bytes in the TUN read/write loop (like PCAPdroid and NetGuard do). This gives per-connection byte counts with zero additional overhead. -- **Data usage alerts**: `NetworkStatsManager` supports bucket-based queries. Implement a periodic `WorkManager` job that checks cumulative usage against user-defined quotas and fires notifications. -- **Per-app bandwidth widget**: Combine `NetworkStatsManager` historical data with VPN real-time counters for a live + historical dashboard. - ---- - -## 3. PCAP / Packet Capture - -### 3.1 PCAPdroid - -| Field | Detail | -|-------|--------| -| **GitHub** | https://github.com/emanuele-f/PCAPdroid | -| **Stars** | ~3,850 | -| **License** | GPL-3.0 | -| **Language** | Java + C | - -**Capture Architecture:** -- VPN mode (no root): creates TUN interface, reads raw IP packets. -- Root mode: uses `libpcap` for raw socket capture. -- Packets processed in native C layer for performance. - -**Export Formats:** -- PCAP and **PCAP-NG** format support. -- Export options: save to file, download via browser, **stream to remote receiver** (e.g., Wireshark over UDP). -- Real-time PCAP streaming enables live analysis on desktop. - -**Protocol Detection (nDPI Integration):** -- Integrates [ntop/nDPI](https://github.com/ntop/nDPI) (4,390 stars) for deep packet inspection. -- Identifies 300+ application protocols from packet patterns. -- Extracts **SNI** from TLS ClientHello. -- Extracts HTTP URLs, DNS queries, remote IP addresses. - -**TLS Metadata & Fingerprinting:** -- nDPI natively supports **JA3** (client + server) and **JA4** (including ja4_r raw) fingerprints. -- nDPI has introduced its own "nDPI fingerprint" combining TCP fingerprint + JA4 + TLS SHA1 certificate. -- PCAPdroid gets JA3/JA4 "for free" through the nDPI integration. - -**TLS Decryption:** -- Optional decryption via customized mitmproxy. -- Decrypted payloads viewable in-app. -- Decrypted traffic exportable as PCAP-NG. - -**Real-Time UI:** -- Connections tab: per-app, per-connection list with protocol, state, destination, bytes. -- Filtering: by IP, host, protocol, app name, UID. -- Long-press context menu for quick filtering and hiding. -- Search bar for real-time connection filtering. - -**Firewall & Malware Detection (Paid Features):** -- Firewall rules to block apps, domains, and IPs. -- **Malware detection via third-party blacklists** (updated daily). -- Blocks traffic to/from malicious hosts in VPN mode. -- Shows count of active IP and domain rules. - -**Key Takeaway for HostShield:** PCAPdroid's nDPI integration is the gold standard for Android packet analysis. Adopt nDPI for protocol detection + JA3/JA4 fingerprinting. The PCAP-NG streaming to remote Wireshark is an excellent power-user feature. The daily-updated malware blacklist model is simple and effective. - ---- - -## 4. GeoIP and Threat Intelligence - -### 4.1 MaxMind GeoLite2 Integration - -| Resource | Detail | -|----------|--------| -| **Java Library** | [maxmind/GeoIP2-java](https://github.com/maxmind/GeoIP2-java) -- 856 stars | -| **Maven** | `com.maxmind.geoip2:geoip2:5.0.2` | -| **Database** | GeoLite2-Country.mmdb, GeoLite2-City.mmdb, GeoLite2-ASN.mmdb | -| **Update Frequency** | Weekly (Tuesdays) | -| **License** | CC BY-SA 4.0 (database), Apache-2.0 (library) | - -**Android Implementation Approach:** -1. Bundle `GeoLite2-Country.mmdb` (~6MB) and `GeoLite2-ASN.mmdb` (~8MB) in assets or download on first launch. -2. Use `DatabaseReader` from GeoIP2-java -- thread-safe, reusable. -3. Enable `CHMCache` for ~2MB memory overhead with faster repeated lookups. -4. For City-level data, `GeoLite2-City.mmdb` is ~70MB -- consider downloading separately and storing on external storage. -5. Implement weekly background update via WorkManager. - -**Mirror for auto-updates:** [P3TERX/GeoLite.mmdb](https://github.com/P3TERX/GeoLite.mmdb) provides auto-updated database mirrors. - -### 4.2 IP Reputation / Threat Intelligence - -**AbuseIPDB:** -- REST API: `GET /api/v2/check?ipAddress=X.X.X.X` -- Free tier: 1,000 checks/day. -- Returns: abuse confidence score (0-100), total reports, country, ISP, usage type. -- Best used for on-demand checks when user inspects a connection, not bulk real-time. - -**Blocklist-based Approach (like PCAPdroid):** -- Download IP/domain blacklists daily (e.g., abuse.ch URLhaus, Spamhaus DROP, Emerging Threats). -- Store as efficient data structures (radix trie for IPs, hash set for domains). -- Check every connection in the VPN loop -- O(1) per lookup. -- This is the practical approach for real-time on-device threat detection. - -**Recommended Feeds:** -| Feed | Type | URL | -|------|------|-----| -| abuse.ch URLhaus | Malware URLs/IPs | https://urlhaus.abuse.ch/api/ | -| Spamhaus DROP | Worst IP ranges | https://www.spamhaus.org/drop/ | -| Emerging Threats | IPs | https://rules.emergingthreats.net/ | -| Disconnect Tracker List | Tracker domains | Used by Firefox, TrackerControl | -| DuckDuckGo Tracker Radar | Tracker domains | Used by TrackerControl | -| Hagezi DNS Blocklists | Ads/trackers/malware domains | Popular in RethinkDNS | - -### 4.3 Connection Visualization - -**Globe / Map View:** -- [geoip-attack-map](https://github.com/MatthewClarkMay/geoip-attack-map) -- real-time globe visualization parsing syslog. -- [geoip-live-map](https://github.com/ramanenka/geoip-live-map) -- real-time access log visualization on a map. -- For Android: use a lightweight WebView-based globe (e.g., Globe.GL / Cesium.js) or a custom OpenGL view. -- Feed connection data from VPN layer: source (device) -> destination (GeoIP-resolved lat/lng). -- LostNet pioneered per-country connection visualization on Android. - -**Key Takeaway for HostShield:** Bundle GeoLite2-Country + ASN databases. Use blocklist-based threat detection for real-time (not API-based). Reserve AbuseIPDB for on-demand "deep check" when user taps a connection. A globe view showing active connections by country would be a strong differentiator. - ---- - -## 5. Privacy Scoring & App Analysis - -### 5.1 Exodus Privacy / ETIP - -| Field | Detail | -|-------|--------| -| **Platform** | [exodus-privacy.eu.org](https://exodus-privacy.eu.org/) | -| **ETIP GitHub** | https://github.com/Exodus-Privacy/etip (71 stars) | -| **Android App** | https://github.com/Exodus-Privacy/exodus-android-app (956 stars) | -| **Database** | https://etip.exodus-privacy.eu.org/ | - -**Tracker Detection Methodology:** -1. **Code signature matching**: Each tracker in ETIP has one or more **Java/Kotlin class name patterns** (e.g., `com.google.android.gms.analytics`, `com.facebook.ads`). -2. The scanner extracts the **DEX class list** from the APK (no execution needed). -3. Pattern matching against the ETIP signature database identifies embedded tracker SDKs. -4. Additionally checks for **domain names** in the APK's string constants. -5. ETIP database fields per tracker: name, code signatures, network signatures (domains), categories, documentation links. - -**On-Device Implementation:** -- The Exodus Android app queries the Exodus web API for pre-analyzed reports. -- For on-device analysis, use Android's `PackageManager` to get the APK path, then extract the DEX class list and match against ETIP signatures. - -### 5.2 ClassyShark3xodus - -| Field | Detail | -|-------|--------| -| **F-Droid** | https://f-droid.org/packages/com.oF2pks.classyshark3xodus/ | - -- Based on Google's ClassyShark (bytecode viewer). -- Scans **installed APKs locally** -- no server needed. -- Matches class names against Exodus ETIP tracker signatures. -- Shows warnings for known trackers found in app bytecode. - -### 5.3 TrackerControl - -| Field | Detail | -|-------|--------| -| **GitHub** | https://github.com/TrackerControl/tracker-control-android | -| **Stars** | ~2,420 | -| **License** | GPL-3.0 | -| **Language** | Java | - -**Dual Detection Methodology:** -1. **Static analysis**: Uses Exodus/ETIP code signatures to detect tracker libraries in APK bytecode. -2. **Network analysis**: VPN-based traffic monitoring matches connections against: - - Disconnect blocklist (used by Firefox) - - DuckDuckGo Tracker Radar (mobile-specific) - - Custom in-house blocklist (derived from analyzing ~2M apps) -3. Combining static + network analysis provides evidence of actual data exfiltration, not just SDK presence. - -### 5.4 Privacy Scoring Model - -**Recommended Scoring Formula for HostShield:** - -``` -Privacy Score = 100 - (tracker_penalty + permission_penalty + network_penalty) - -tracker_penalty: - - Per tracker SDK detected: -5 points (max -40) - - Analytics trackers: -3 each - - Advertising trackers: -5 each - - Fingerprinting trackers: -7 each - -permission_penalty: - - Each dangerous permission: weighted by severity - - CAMERA, MICROPHONE, LOCATION: -5 each - - CONTACTS, CALL_LOG, SMS: -4 each - - STORAGE, PHONE_STATE: -2 each - - Total cap: -30 - -network_penalty: - - Connections to known tracker domains: -3 per unique domain (max -20) - - Connections to countries with poor privacy laws: -2 per country - - Unencrypted HTTP connections: -5 per unique host - - Total cap: -30 -``` - -**Implementation Steps:** -1. On app install / periodic scan: extract class list from APK, match against ETIP database. -2. Query `PackageManager` for declared permissions. -3. When VPN is active: log destination domains per app, match against tracker blocklists. -4. Compute composite score, cache results, surface in app detail view. - -**Key Takeaway for HostShield:** Combine Exodus ETIP static detection with real-time network-based tracker detection (like TrackerControl). The dual approach proves actual data sharing, not just SDK presence. The ETIP database is the canonical source for Android tracker signatures. - ---- - -## 6. Network Security Tools - -### 6.1 DNS Leak Testing - -**How It Works:** -1. Generate unique random subdomain queries (e.g., `.test.dnsleaktest.com`). -2. Send DNS queries through the device's configured resolver. -3. The authoritative server logs which recursive resolver IP made the query. -4. Compare resolver IP against expected VPN/DoH endpoint. -5. If resolver IP belongs to the ISP instead of the VPN provider, DNS is leaking. - -**On-Device Implementation:** -- Create a simple authoritative DNS server endpoint (or use existing services). -- Perform lookups from the app and check if responses come from the expected resolver. -- Alternatively, inspect DNS traffic in the VPN layer to detect queries bypassing the tunnel. - -### 6.2 WebRTC Leak Detection - -**How It Works:** -- WebRTC uses STUN servers to discover the device's public and local IP addresses. -- A STUN request can bypass VPN tunnels and reveal the real IP. -- Detection: use a WebView to run JavaScript that calls `RTCPeerConnection`, extract ICE candidates, compare IPs against VPN-assigned IP. - -**On-Device Implementation:** -- Load a local HTML page in a WebView with JavaScript that creates an `RTCPeerConnection`. -- Parse ICE candidates for IP addresses. -- Compare discovered IPs with the VPN tunnel's assigned IP. -- Flag any IP that doesn't match the VPN as a potential leak. -- Mitigation: Android's WebView can disable WebRTC via `chrome://flags` or by intercepting STUN traffic in the VPN layer. - -### 6.3 IPv6 Leak Detection - -**How It Works:** -- Many VPNs only tunnel IPv4 traffic, leaving IPv6 unprotected. -- Detection: attempt IPv6 connections to known test servers; if successful while VPN is active, IPv6 is leaking. - -**On-Device Implementation:** -- Attempt connections to IPv6-only endpoints (e.g., `ipv6.icanhazip.com`). -- If reachable and the returned IP is not the VPN's IPv6 address, flag as leak. -- Mitigation: block all IPv6 traffic in the VPN's TUN interface configuration (don't add IPv6 routes), or explicitly tunnel IPv6. - -### 6.4 Captive Portal Detection & Handling - -**Android Native Approach:** -- Android uses `NetworkMonitor` (in `com.android.server.connectivity`) to detect captive portals. -- Sends HTTP probe to `connectivitycheck.gstatic.com/generate_204` and HTTPS probe simultaneously. -- If HTTP returns 200 (not 204) or HTTPS fails, captive portal is detected. -- Android 11+ supports RFC 7710bis captive portal API. - -**HostShield Implementation:** -- Hook into `ConnectivityManager.NetworkCallback` to receive `onCapabilitiesChanged` with `NET_CAPABILITY_CAPTIVE_PORTAL`. -- When captive portal detected: temporarily pause VPN/firewall rules, show notification to user, open captive portal login in Custom Tabs. -- After authentication (portal check passes), re-enable VPN/firewall. -- Use `CaptivePortal.reportCaptivePortalDismissed()` on Android 11+. - -**Open Source Reference:** -- [Captive Portal Controller](https://f-droid.org/packages/io.github.muntashirakon.captiveportalcontroller/) on F-Droid. -- [IPCheck.ing](https://github.com/jason5ng32/MyIP) (9,990 stars) -- open source IP toolbox with DNS leak, WebRTC leak, and IPv6 leak testing. - ---- - -## 7.

Hosts File Diffing - -### Current Landscape - -There is **no widely-adopted dedicated tool** for blocklist diffing. Most projects rely on: - -- **Git history**: StevenBlack/hosts and hagezi track changes via git commits -- **Git diff**: Standard `git diff` on the raw list files -- **Manual log inspection**: Users compare query logs before/after updates - -### Approaches Worth Implementing - -1. **Set-Based Diff**: - ``` - added = new_version - old_version - removed = old_version - new_version - unchanged = old_version ∩ new_version - - Output: - + 142 domains added - - 87 domains removed - = 85,834 domains unchanged - ``` - -2. **Categorized Diff** (enhanced): - - Group added/removed domains by category (if list metadata available) - - Flag notable additions (e.g., major services newly blocked) - - Show source attribution for merged lists (which upstream list caused the change) - -3. **Update Impact Preview**: - - Before applying an update, show: - - New domains that would be blocked (cross-reference with user's query history) - - Domains that would be unblocked - - Rules that changed priority or modifiers - -4. **Changelog Generation**: - - Auto-generate human-readable changelog for each list update - - Include: date, version, domains added/removed count, notable changes - - Store history for rollback capability - -### Implementation Approach for HostShield - -``` -When a list update is fetched: - 1.

VPN-Based DNS Blocking Apps - -### 1.1 AdGuard for Android -- **GitHub:** [AdguardTeam/AdguardForAndroid](https://github.com/AdguardTeam/AdguardForAndroid) (~1.7k stars, open bug tracker only) -- **Key Libraries:** [AdguardTeam/DnsLibs](https://github.com/AdguardTeam/DnsLibs) (C++ DNS filtering/encryption library), [urlfilter](https://github.com/AdguardTeam/urlfilter) (Go filtering engine) -- **Technical Approach:** Uses Android VpnService to intercept all traffic. The core filtering engine (CoreLibs) is cross-platform C++. DnsLibs handles DNS packet processing, filtering, and encrypted DNS (DoH, DoT, DoQ per RFC 9250). Dynamic VPN protocol selection auto-picks HTTP/2 TLS or HTTP/3 QUIC. -- **Notable Features for HostShield:** - - **CNAME tracker database:** AdGuard maintains [cname-trackers](https://github.com/AdguardTeam/cname-trackers) -- a continuously auto-updated list of CNAME-cloaked trackers discovered via their DNS infrastructure. HostShield should consume this list. - - **DNS filtering rule syntax:** AdGuard's rule syntax supports wildcards, regex, client-based rules, and denyallowed modifiers. Consider adopting a compatible rule format. - - **DoQ support (RFC 9250):** DnsLibs implements production-grade DNS-over-QUIC. HostShield should add DoQ alongside DoH. - -### 1.2 DNS66 -- **GitHub:** [julian-klode/dns66](https://github.com/julian-klode/dns66) (~2.2k stars) -- **Technical Approach:** Pure Java. Establishes a local-only VPN and redirects all DNS server routes into it. The VPN filters DNS queries against a host blocklist; non-blocked queries are forwarded to upstream DNS. No proxy layer -- just raw packet filtering. -- **Notable Features for HostShield:** - - **Simplicity of DNS-only VPN routing:** DNS66 only routes DNS traffic (port 53) through the VPN rather than all traffic, reducing overhead. If HostShield routes all traffic, consider a DNS-only mode for battery optimization. - - **Host list priority model:** Later entries override earlier ones, allowing user overrides to take precedence cleanly. - -### 1.3 Blokada 5/6 -- **GitHub:** [blokadaorg/blokada](https://github.com/blokadaorg/blokada) (~3.2k stars), [blokadaorg/five-android](https://github.com/blokadaorg/five-android) -- **Technical Approach:** Blokada 5 uses on-device VPN-based DNS interception (similar to DNS66). Blokada 6 moved to cloud-based DNS filtering (subscription model). Installs as an "on-device only" VPN inside the Android networking stack. -- **Notable Features for HostShield:** - - **Battery-optimized VPN:** Blokada's claim of minimal battery drain suggests careful use of `VpnService.Builder.addRoute()` to only capture DNS packets (port 53 UDP/TCP) rather than all traffic. - - **Cloud/local hybrid model:** Blokada 6's cloud approach could inspire an optional remote blocklist sync mode where a HostShield server pre-compiles trie updates. - -### 1.4 NetGuard -- **GitHub:** [M66B/NetGuard](https://github.com/M66B/NetGuard) (~3.5k stars) -- **Technical Approach:** VPN-based per-app firewall with DNS blocking. The critical differentiator: **native C code (`dns.c`) for packet parsing** on the TUN interface. This provides high-performance packet capture at the kernel/userspace boundary. -- **Notable Features for HostShield:** - - **Native DNS packet parser in C:** NetGuard's `app/src/main/jni/netguard/dns.c` handles raw DNS packet parsing in native code via JNI for speed. HostShield could benefit from a similar native layer for its packet builder/parser instead of pure Kotlin. - - **Per-app DNS blocking:** Blocks on real domain names with per-app granularity by tracking which app owns each connection via `ConnectivityManager`. - - **Custom TTL override:** NetGuard allows users to override DNS TTL values, compensating for Android's non-standard DNS caching behavior. -- **Limitation:** Cannot intercept DoH/DoT traffic since it is encrypted end-to-end. - -### 1.5 InviZible Pro -- **GitHub:** [Gedsh/InviZible](https://github.com/Gedsh/InviZible) (~2.5k stars) -- **Technical Approach:** Bundles three standalone binaries -- DNSCrypt, Tor, and Purple I2P -- and manages them as Android services. Supports **three operation modes**: VPN mode (local VPN), Root mode (iptables redirection), and Proxy mode (no VPN, no iptables). -- **Notable Features for HostShield:** - - **Tri-mode architecture:** The cleanest reference for dual/tri-mode (VPN + root + proxy) DNS routing. HostShield's VPN + root model could add a proxy mode for compatibility with other VPNs. - - **iptables rule refresh on connectivity change:** InviZible refreshes iptables rules on every connectivity change event -- critical for root mode reliability when switching between WiFi/cellular. - - **DNSCrypt integration:** Pre-built DNSCrypt binary management. HostShield could integrate DNSCrypt protocol support natively in Kotlin rather than shelling out to a binary. - - **Firewall with module awareness:** The firewall only activates when DNSCrypt/Tor are running, demonstrating clean lifecycle coupling. - -### 1.6 personalDNSfilter -- **GitHub:** [IngoZenz/personaldnsfilter](https://github.com/IngoZenz/personaldnsfilter) (~857 stars) -- **Technical Approach:** Pure Java DNS filter proxy. Hooks into DNS resolution and returns loopback (127.0.0.1) for filtered hosts. Can run as a local DNS proxy on the device OR as a network-wide DNS server. -- **Notable Features for HostShield:** - - **LRU cache for filter results:** Caches both allowed and blocked domain lookups to avoid repeated trie/list traversals. HostShield should ensure its cache covers both positive and negative filter decisions, not just DNS responses. - - **Network server mode:** Can serve as a DNS server for an entire LAN. HostShield could add a "share protection" mode where one device filters DNS for the whole network. - - **DoH + DoT upstream support:** Supports encrypted upstream resolution without root. - -### 1.7 Nebulo -- **GitHub:** [Ch4t4r/Nebulo](https://github.com/Ch4t4r/Nebulo) (~236 stars) -- **Technical Approach:** Creates a local-only VPN that intercepts **only DNS requests** and encrypts them. Zero dependencies for core DNS capabilities -- entirely original DNS protocol implementation. -- **Notable Features for HostShield:** - - **DNS-over-QUIC (DoQ) support:** One of the few Android apps implementing DoQ alongside DoH and DoT. HostShield should prioritize DoQ given the RFC 9250 standardization. - - **Configurable in-memory DNS cache with custom expiry:** Rather than blindly following TTL, allows user-configurable cache lifetimes. - - **Multiple blocklist format support:** Supports 4 different blocklist formats (hosts files, domains-only, adblock-style, dnsmasq-style). HostShield should support all common formats. - - **Zero-dependency DNS implementation:** Proves that a purpose-built DNS stack (no dnsjava/minidns dependency) can be lighter and more tailored for mobile. - -### 1.8 RethinkDNS -- **GitHub:** [celzero/rethink-app](https://github.com/celzero/rethink-app) (~4.7k stars, Kotlin 99.7%) -- **Technical Approach:** Kotlin-native Android app combining DNS-over-HTTPS, DNS-over-TLS, DNSCrypt, DNS-over-Tor, WireGuard proxifier, and per-app firewall. Uses Go (`firestack`) for UDP/TCP connection handling via `gomobile`. Per-app connection mapping via `ConnectivityService`. -- **Notable Features for HostShield:** - - **Succinct Radix Trie for blocklist compression:** RethinkDNS compresses ~17M entries from 200+ blocklists into a succinct radix trie (based on Steve Hanov's implementation, modified for faster lookup). This is the most advanced domain lookup structure in the Android ad-blocking space. **HostShield's trie-based domain lookup should evaluate adopting a succinct/compressed radix trie.** - - **CNAME + HTTPS/SVCB cloaking detection:** Follows CNAME chains and HTTPS/SVCB redirects, matching each hop against blocklists. This is the gold standard for CNAME cloak detection on Android. - - **Time-based blocking rules:** Allows temporary website blocks with time-based rules -- a useful UX feature. - - **DNS-over-Tor:** Routes DNS through Tor for maximum anonymity. Consider as an optional mode. - - **WireGuard split-tunnel integration:** Allows using a real VPN alongside the DNS firewall. Solves the "only one VPN at a time" Android limitation. - ---- - -## 2. Root-Based DNS Blocking - -### 2.1 AdAway -- **GitHub:** [AdAway/AdAway](https://github.com/AdAway/AdAway) (~8.9k stars -- highest in this category) -- **Dual-mode:** Root method modifies `/system/etc/hosts`; non-root method uses VPN-based filtering. -- **Root hosts file approach:** - - Writes blocked domains to the system hosts file mapping them to `127.0.0.1` or `0.0.0.0` - - Requires remounting `/system` as read-write (increasingly difficult on modern Android with system-as-root, SAR, and dynamic partitions) - - Optional local web server responds to blocked host requests (prevents connection timeout delays) -- **Actionable for HostShield:** - - **Hosts file as fallback:** Even with iptables-based blocking, writing a hosts file provides a belt-and-suspenders approach that survives service crashes. - - **Local web server for blocked responses:** Returning a proper HTTP response (empty page/pixel) for blocked domains prevents UI hangs in apps waiting for timeouts. HostShield should return immediate NXDOMAIN or A-record pointing to a local responder. - -### 2.2 iptables/nftables DNS Redirection Patterns - -**Current iptables approach (used by InviZible Pro, AFWall+, HostShield):** -```bash -# Redirect all DNS to local proxy -iptables -t nat -A OUTPUT -p udp --dport 53 -j REDIRECT --to-port 5353 -iptables -t nat -A OUTPUT -p tcp --dport 53 -j REDIRECT --to-port 5353 - -# Block direct DNS bypass (prevent apps using hardcoded DNS) -iptables -A OUTPUT -p udp --dport 53 ! -d 127.0.0.1 -j DROP -iptables -A OUTPUT -p tcp --dport 53 ! -d 127.0.0.1 -j DROP - -# Also intercept DoT (port 853) -iptables -t nat -A OUTPUT -p tcp --dport 853 -j REDIRECT --to-port 5353 -``` - -**NFLOG integration pattern:** -```bash -# Log all DNS queries for analytics before filtering -iptables -A OUTPUT -p udp --dport 53 -j NFLOG --nflog-group 1 --nflog-prefix "DNS" -# Userspace reads from NFLOG group via libnetfilter_log or nflog socket -``` - -**nftables migration considerations:** -- AFWall+ (the leading Android iptables firewall, [ukanth/afwall](https://github.com/ukanth/afwall)) has **not yet migrated to nftables** -- Android 12+ ships with nftables support in the kernel, but the `iptables` binary is still present as a compatibility shim (`iptables-nft`) -- **Recommendation for HostShield:** Detect whether the device uses legacy iptables or nftables backend (`iptables -V` shows `nf_tables` or `legacy`). Use the iptables command-line compatibility layer for now, but architect the rule generation to be backend-agnostic for future nftables native support. - -### 2.3 Root Detection and Binary Management -- **InviZible Pro pattern:** Bundles pre-compiled arm/arm64/x86 binaries for DNSCrypt, Tor, I2P. Extracts to app private directory, sets executable permissions, manages lifecycle via `ProcessBuilder`. -- **AdAway pattern:** Uses `su` binary for root commands. Detects root via Magisk/SuperSU/KernelSU APIs. -- **Recommendation for HostShield:** Support KernelSU detection alongside Magisk and legacy SuperSU. Use `libsu` (topjohnwu's library) for modern root shell management. - ---- - -## 3. DNS Packet Parsing/Building - -### 3.1 Library Comparison - -| Library | Stars | Language | EDNS | DNSSEC | Android Support | Size | -|---------|-------|----------|------|--------|-----------------|------| -| [dnsjava](https://github.com/dnsjava/dnsjava) | ~1.1k | Java | EDNS0 | Full (validating stub resolver) | Yes (via ConnectivityManager init) | ~500KB | -| [MiniDNS](https://github.com/MiniDNS/minidns) | ~243 | Java | EDNS0 | DNSSEC + DANE (not audited) | Yes (minidns-android23 module) | Modular, ~100KB core | -| NetGuard `dns.c` | N/A | C (JNI) | No | No | Native | Minimal | -| Nebulo (custom) | N/A | Kotlin | Partial | No | Yes | Zero-dep | - -### 3.2 Recommendations for HostShield - -**Option A: Hybrid approach (recommended)** -- Use a **Kotlin-native DNS packet builder/parser** for the hot path (query construction, response parsing, cache lookup). This avoids JNI overhead for simple operations. -- Use **dnsjava** as a dependency for complex operations: DNSSEC validation, TSIG, zone transfers, and full record type coverage. -- Use **JNI/native C** only for the VPN TUN interface read/write loop (like NetGuard's approach) where zero-copy buffer handling matters. - -**Option B: Full native DNS stack** -- Port the packet builder to C/Rust via JNI for maximum performance. -- Suitable if HostShield processes >10K queries/sec (unlikely on mobile but relevant for network-server mode). - -**EDNS support specifics:** -- Implement EDNS0 (RFC 6891) with OPT pseudo-record in all queries -- Support EDNS Client Subnet (ECS, RFC 7871) -- important for CDN optimization but privacy-sensitive; make it opt-in -- Set EDNS buffer size to 1232 bytes (per DNS Flag Day 2020 recommendation) to avoid fragmentation -- Include EDNS padding (RFC 7830) for DoH/DoT queries to prevent traffic analysis - ---- - -## 4. DNS Caching Strategies - -### 4.1 TTL Handling -- **Standard:** Cache responses for the minimum TTL across all RRs in the answer section. -- **Android quirk:** Android's built-in resolver ignores DNS TTL and applies its own caching. HostShield must operate its own cache independent of the system resolver (which it already does via VPN interception). -- **Cap maximum TTL:** Implement a configurable max TTL cap (e.g., 86400 seconds / 1 day) per RFC 8767's suggestion of 7-day maximum. RethinkDNS and Nebulo both allow user-configurable cache expiry. - -### 4.2 Negative Caching (RFC 2308, RFC 9520) -- Cache NXDOMAIN and NODATA responses using the SOA record's minimum TTL. -- **RFC 9520 (2024):** Also cache resolution failures (SERVFAIL, timeouts) with a short TTL (e.g., 1-5 seconds) to prevent retry storms against failing upstreams. -- HostShield should differentiate between: - - NXDOMAIN (domain doesn't exist) -- cache for SOA minimum TTL - - NODATA (domain exists, no records of requested type) -- cache for SOA minimum TTL - - SERVFAIL from upstream -- cache for 1-5 seconds (configurable) - - Network timeout -- cache for 1 second, then retry with exponential backoff - -### 4.3 Prefetching (Proactive Cache Refresh) -- **Unbound's algorithm:** When a cached entry's remaining TTL drops below 10% of original TTL, serve the stale entry to the client and dispatch a background refresh. -- **Implementation for HostShield:** - ``` - if (entry.remainingTTL < entry.originalTTL * 0.10 && entry.queryCount > threshold) { - serveFromCache(entry) // respond immediately - backgroundRefresh(entry) // async upstream query - } - ``` -- Only prefetch for **popular domains** (track query frequency). A simple counter with a threshold (e.g., >3 queries during the TTL period) prevents wasting bandwidth on rarely-queried domains. -- **Trade-off:** ~10% increase in upstream queries, but dramatically improves perceived latency for frequently-accessed domains. - -### 4.4 Serve-Stale (RFC 8767) -- When an upstream resolver is unreachable, serve expired cache entries rather than returning SERVFAIL. -- Set a **stale TTL cap** (e.g., 1-3 days beyond original expiry). -- Mark stale responses with a low TTL (e.g., 30 seconds) so clients re-query soon. -- **Implementation priority:** This is critical for mobile where connectivity is intermittent. When the device switches between WiFi/cellular, there's a brief period where DNS resolution may fail. Serve-stale bridges this gap seamlessly. -- Akamai has used this in production since 2011; BIND 9.12+ and Unbound both implement it. - -### 4.5 Cache Architecture Recommendation -``` -HostShield DNS Cache -+-- L1: In-memory LRU (hot entries, ~10K domains) -| +-- Positive cache (A, AAAA, CNAME, etc.) -| +-- Negative cache (NXDOMAIN, NODATA) -| +-- Filter decision cache (blocked/allowed per personalDNSfilter pattern) -+-- L2: On-disk persistent cache (survives app restart, ~100K domains) -| +-- SQLite or memory-mapped file -+-- Prefetch queue (background refresh for entries at <10% TTL) -``` - ---- - -## 5. Encrypted DNS - -### 5.1 Protocol Support Matrix Across Projects - -| Project | DoH | DoT | DoQ | DNSCrypt | DNS-over-Tor | -|---------|-----|-----|-----|----------|--------------| -| AdGuard | Yes | Yes | Yes (RFC 9250) | Yes | No | -| DNS66 | No | No | No | No | No | -| Blokada 5 | No | No | No | No | No | -| NetGuard | No | No | No | No | No | -| InviZible Pro | Via DNSCrypt binary | No | No | Yes | Yes (via Tor) | -| personalDNSfilter | Yes | Yes | No | No | No | -| Nebulo | Yes | Yes | Yes | No | No | -| RethinkDNS | Yes | Yes | No | Yes | Yes | -| **HostShield (current)** | **Yes** | **No** | **No** | **No** | **No** | - -**Priority additions for HostShield:** -1. **DoT (DNS-over-TLS, RFC 7858):** Simpler than DoH, lower overhead, widely supported. Use Android's built-in TLS stack. -2. **DoQ (DNS-over-QUIC, RFC 9250):** Growing adoption, supported by AdGuard DNS, Cloudflare (experimental), NextDNS. Use a QUIC library like `cronet` (Chromium's QUIC stack available as an Android library) or `kwik` (pure Java QUIC). -3. **DNSCrypt:** Still relevant for privacy-focused users. Can wrap dnscrypt-proxy binary or implement the protocol natively. - -### 5.2 CNAME Cloaking Detection - -**Current state of the art:** -- **RethinkDNS:** Follows CNAME chains AND HTTPS/SVCB record redirects, matching each hop against blocklists. This is the most comprehensive approach. -- **AdGuard:** Maintains a continuously-updated [CNAME tracker list](https://github.com/AdguardTeam/cname-trackers) discovered by scanning the web at scale. -- **NextDNS:** Maintains [cname-cloaking-blocklist](https://github.com/nextdns/cname-cloaking-blocklist) of known CNAME cloaking destinations. -- **uBlock Origin (Firefox):** Uses browser DNS API to resolve CNAME chains and match against filter lists. Blocks ~70% of CNAME-cloaked trackers. - -**Recommended implementation for HostShield:** -``` -1. Intercept DNS response -2. If response contains CNAME records: - a. Resolve the full CNAME chain (follow up to N=8 hops) - b. Check EACH domain in the chain against blocklists - c. If ANY domain in the chain matches a blocklist, block the original query -3. If response contains HTTPS/SVCB records: - a. Extract TargetName from SVCB/HTTPS records - b. Check TargetName against blocklists -4. Consume both AdGuard cname-trackers and NextDNS cname-cloaking-blocklist -5. Cache CNAME chains to avoid repeated resolution overhead -``` - -### 5.3 ECH (Encrypted Client Hello) Considerations - -- **RFC 9849** (published 2025) standardizes ECH for TLS 1.3. -- ECH encrypts the SNI field using keys published in DNS SVCB/HTTPS records. -- **Impact on HostShield:** ECH makes it impossible to determine the destination server from TLS handshake alone. DNS-level blocking becomes the **only** viable blocking layer when ECH is deployed. -- **Actionable steps:** - - Parse HTTPS/SVCB records (TYPE 64/65) in DNS responses to extract ECHConfig - - Log ECH-enabled domains for user visibility - - Consider blocking HTTPS/SVCB records that contain ECHConfig for blocked domains (prevents clients from establishing ECH connections to tracker domains) - - Support SVCB-aware DNS resolution to properly handle AliasMode (SVCB with TargetName) and ServiceMode records - -### 5.4 DNSSEC Validation - -**Library options:** -- **dnsjava:** Full DNSSEC validating stub resolver, based on Unbound Java prototype. Production-tested. Supports Extended DNS Errors (EDE, RFC 8914) for validation failure reasons. -- **MiniDNS:** DNSSEC + DANE support via `minidns-dnssec` module, but has NOT undergone security audit. More lightweight. -- **dnssecjava** ([ibauersachs/dnssecjava](https://github.com/ibauersachs/dnssecjava)): Standalone DNSSEC validating stub resolver for Java, can complement dnsjava. - -**Recommendation for HostShield:** -- Implement DNSSEC validation as opt-in (it adds latency and many domains are not signed). -- Use dnsjava's DNSSEC module for validation. -- Display DNSSEC status (secure/insecure/bogus) in the query log UI. -- For bogus responses (failed validation), return SERVFAIL with EDE code. - -### 5.5 DNS Stamps (`sdns://`) - -DNS stamps encode all parameters to connect to a DNS resolver in a single compact string: -- Format: `sdns://` prefix + base64url-encoded configuration -- Supports: DNSCrypt, DoH, DoT, DoQ, Oblivious DoH, plain DNS, DNS relay -- Used by: dnscrypt-proxy, AdGuard, NextDNS, Simple DNSCrypt, RethinkDNS - -**Recommendation for HostShield:** -- Implement DNS stamp parsing/generation per the [specification](https://dnscrypt.info/stamps-specifications/) -- Allow users to add servers by pasting `sdns://` stamps (much easier than manual IP/hostname/path configuration) -- Pre-populate with stamps for popular resolvers (Cloudflare, Google, Quad9, NextDNS, AdGuard DNS, Mullvad) -- Support stamp QR code scanning for easy mobile configuration sharing - ---- - -## 6.
