PtyOutput user_event scope-locks Term, feeds bytes, drops Phase-1 NSTextField overlay exactly once on first byte (D-51), then request_redraw. RedrawRequested paints clear-color. - vector-app::pty_actor: I/O thread spawns LocalDomain, pumps reader.recv() -> EventLoopProxy (Plan 02-05 actor pattern; Plan 03-04 will add input channel + biased select!). - UserEvent gains PtyOutput(Vec); Tick(u64) retained but unused (tick.rs marked #[allow(dead_code)]; Plan 03-05 deletes). - pipeline_init test: probes Metal adapter without surface (CI-safe). - win_style_mask test: compile-checks NSWindowStyleMask import path. - Rule 1 deviations: * wgpu 29 API drift from plan: InstanceDescriptor no longer impl Default (use new_without_display_handle()); DeviceDescriptor gained required experimental_features field; RenderPassDescriptor gained required multiview_mask; RenderPassColorAttachment gained required depth_slice; get_current_texture returns CurrentSurfaceTexture enum (not Result); request_adapter returns Result (not Option). * clippy::needless_pass_by_value forced &Arc instead of Arc in RenderContext::new / RenderHost::new. - Rule 3 deviation: vector-render arch-lint BLOCK_ON_ALLOWLIST extended with pipeline.rs (pollster::block_on bridges wgpu's async init on the main thread; never on tokio reactor — D-09 invariant holds). - 55 passed (+2 from baseline: pipeline_init + win_style_mask now run); 0 failed; 18 ignored; arch-lint 15==15 holds. - Manual smoke: cargo run -p vector-app --release alive

Eliminates the held-Mutex-across-await pattern entirely — no `tokio::sync::Mutex` over the transport; `clippy::await_holding_lock = "deny"` (D-11) holds at compile time. User-approved 5-step smoke matrix on host parent terminal: `echo hello` / vim / tmux+split / htop / `less +F` — all PASS. CORE-04 verified live (parent terminal resize reflowed tmux pane + htop layout within ~1s). Two task commits: `ab50bf1` + `4a107b0`; Task 3 is a manual UAT checkpoint per VALIDATION.md §"Manual-Only Verifications" (no commit; user "approved" reply 2026-05-11T16:55Z is the gate). Three auto-fixed code deviations: Rule 2 (hide-cursor `\x1b[?25l ... \x1b[?25h` bracketing each frame to kill the 30Hz strobe of cursor positioning), Rule 3 (best-effort raw mode — skip `enable_raw_mode()` when stdin isn't a tty so CI / `< /dev/null` smokes work), Rule 3 (added `alacritty_terminal` as direct binary-local dep for `Color`/`Cell`/`Point` types in `render.rs`; re-export via vector-term would have polluted that crate's public API). One documented-not-fixed shell-side behavior: zsh in `/dev/null` mode holds its prompt on lone EOT (acceptable per plan acceptance criteria — interactive smokes all exit cleanly with `exit` keystroke). Phase 2 closes; Phase 3 (GPU renderer) inherits the Term + PTY + transport plumbing untouched and only swaps `render.rs` for a wgpu glyph atlas (actor pattern, SharedTerm `Arc>`, SIGWINCH watcher, scopeguard discipline all carry forward). - **Phase 2 Plan 04 (Wave 3) complete (2026-05-11):** `vector-mux` ships `PtyTransport` + `Domain` traits in their FINAL D-38 shape (`async_trait` boxed futures; `Send + 'static` / `Send + Sync` respectively). `LocalDomain` fully implemented: `$SHELL` → `/etc/passwd` (keyed by `id -un`) → `/bin/zsh` → `/bin/bash` resolution chain; `LocalDomain::spawn(SpawnCommand)` returns `Box` wrapping `LocalPty` via the `LocalTransport` newtype (the newtype lives in vector-mux, NOT in vector-pty, to avoid a vector-pty → vector-mux dep cycle while keeping the trait surface in the consumer crate per D-38). `CodespaceDomain::spawn` `unimplemented!("Phase 7")`; `DevTunnelDomain::spawn` `unimplemented!("Phase 8")`; both `reconnect` bodies `unimplemented!("Phase 9: Persistence + reconnect")`. 8 tests pass: 2 compile-time object-safety, 3 label/alive, 2 should_panic phase markers, and **1 end-to-end CORE-04/05 reachability proof** (`LocalDomain::spawn` of `sh -c "echo hi"` through `Box` collects "hi" via `take_reader()` and gets `Ok(Some(0))` from `wait()` — proving the trait surface, not just direct LocalPty, carries CORE-04 clean-exit and CORE-05 TERM env). One surface change in vector-pty: `LocalPty::write(&self)` → `LocalPty::write(&mut self)` (Rule 3 blocking fix — `Box` is `!Sync` so the trait-object Send-future bound forced `&mut self` borrow; no vector-pty caller invokes `.write` in Plan 02-03's tests so the change is zero-risk to existing contracts). Two task commits: b88a02d + c0ad634.

CORE-01 (CSI/OSC/DCS/partial-UTF-8/alt-screen-1049/DECSTBM/ED/EL), CORE-02 (24-bit + 256-color SGR via `Color::Spec(Rgb)` / `Color::Indexed(u8)` + CJK/emoji-ZWJ `WIDE_CHAR + WIDE_CHAR_SPACER` flags), CORE-03 (10k+ scrollback regex via streaming `RegexSearch`+`RegexIter`, ~150ms — Pitfall 7 honored), CORE-06 (BRACKETED_PASTE + MOUSE_REPORT_CLICK + SGR_MOUSE bit toggles) all covered. search.rs ships with Task 1 (c4bb201) because the ED-2-vs-scrollback test consumes it; Task 2 (5a1fc48) lands CORE-02/03 fixtures. Four auto-fixed deviations (clippy cast lints + manual_let_else + rustfmt assert wrap + the discovery that `\b` doesn't fire in regex_automata's hybrid DFA — substring patterns are our search contract).

Every later Phase 3 plan compiles against these exact versions. +- **wgpu Metal pipeline operational** — `vector-render::RenderContext` creates a `Surface<'static>` over `Arc`, configures it with `PresentMode::Fifo` (D-45) on the Metal backend, and clears to xterm-256 dark gray (`#0F0F0F`) per `render_clear_default()`. Recoverable surface states (Suboptimal/Outdated/Lost/Occluded/Timeout) log+skip; Validation surfaces as an error. +- **I/O actor wired** — `vector-app::pty_actor::io_main` spawns `LocalDomain::new()?` on the tokio I/O thread, requests a 24×80 PTY, and pumps `reader.recv() -> EventLoopProxy::send_event(UserEvent::PtyOutput(chunk))`. Single-owner discipline holds: only this task touches the transport (Plan 02-05 actor pattern carries forward intact). +- **Phase-1 overlay drops exactly once on first PtyOutput** — `App::user_event` scope-locks `Arc>`, calls `Term::feed(&bytes)`, drops the lock, then nulls `self.overlay = None` exactly once (D-51) before calling `request_redraw()`. `clippy::await_holding_lock = "deny"` is satisfied at compile time. +- **Term::damage() / reset_damage() exposed** — Plan 03-03's compositor seam is in place. `TermDamage`, `TermDamageIterator`, `LineDamageBounds` re-exported via `vector_term::*` so `vector-render` does not need a direct `alacritty_terminal` dep. +- **20 Wave-0 #[ignore] test stubs live on disk** covering every remaining Phase 3 plan target (mapping below). `cargo test --workspace --tests` reports 55 passed / 0 failed / 18 ignored on completion (baseline 53, +2 = `pipeline_init` + `win_style_mask` un-ignored by this plan). + +## Task Commits + +1. **Task 1: Wave-0 test stubs + workspace deps + Term::damage() wrapper** — `cd0159d` (feat) +2. **Task 2: wgpu surface lifecycle + clear-color frame + I/O actor wiring** — `eea4540` (feat) + +_Plan metadata commit lands separately after this SUMMARY._ + +## Files Created/Modified + +**Created (src):** +- `crates/vector-render/src/pipeline.rs` — `RenderContext::new(&Arc)` + `resize(w,h)` + `render_clear(&[f64;4])`.

Shipped 20, matching the file list. See Deviations. + +## Decisions Made + +- **Surface<'static> via Arc**: wgpu 29's `SurfaceTarget::DisplayAndWindow(Box)` accepts `Arc` (winit's `Window` implements the trait). Cloning the Arc into the surface decouples its lifetime from the caller's scope. `App` retains `Option>` for `request_redraw()` and resize. +- **render_clear returns `anyhow::Result<()>`** (not `Result<(), wgpu::SurfaceError>` as written in the plan). wgpu 29 replaced `SurfaceError` with the `CurrentSurfaceTexture` enum — see Deviations below. +- **`pollster::block_on` allowlisted in vector-render's arch-lint** with a single entry: `pipeline.rs`. wgpu's adapter/device init is async-typed but executes synchronously on the macOS main thread (Metal requires it). Bridging via pollster keeps the call out of any tokio reactor; the D-09 invariant (no PTY async on the main thread) is preserved. +- **`#[ignore]` attributes carry a reason string** (`#[ignore = "Wave-0 stub"]`) — workspace clippy lints have `clippy::ignore_without_reason = warn` rolled up by `pedantic`, and `-D warnings` promotes it to deny. See Rule 1 deviation. +- **`tick.rs` kept on disk** with the module declaration marked `#[allow(dead_code)]`.

[Rule 1 - Bug] wgpu 29.0.3 API drift from plan's documented snippets** +- **Found during:** Task 2 (RenderContext::new initial compile) +- **Issue:** Plan reproduced wgpu 29 example code that does not match the published 29.0.3 surface: + - `InstanceDescriptor` no longer implements `Default`; must use `InstanceDescriptor::new_without_display_handle()` and assign fields. + - `Instance::new(desc: InstanceDescriptor)` takes the descriptor by value (not by reference). + - `DeviceDescriptor` gained a required `experimental_features: ExperimentalFeatures` field. + - `RenderPassDescriptor` gained a required `multiview_mask: Option` field. + - `RenderPassColorAttachment` gained a required `depth_slice: Option` field. + - `Surface::get_current_texture()` returns the `CurrentSurfaceTexture` enum (Success | Suboptimal | Timeout | Occluded | Outdated | Lost | Validation), not `Result` — `?` does not apply. + - `Instance::request_adapter` returns `Future>` (not `Option`). +- **Fix:** Rewrote `pipeline.rs` against the actual 29.0.3 API: constructed `InstanceDescriptor` via `new_without_display_handle()`, added `experimental_features: ExperimentalFeatures::disabled()` to `DeviceDescriptor`, added `multiview_mask: None` to `RenderPassDescriptor`, added `depth_slice: None` to `RenderPassColorAttachment`, replaced `Result<…, SurfaceError>` with `anyhow::Result<()>` and pattern-matched `CurrentSurfaceTexture`, replaced `.ok_or_else(…)?` with `.map_err(|e| anyhow!(…))?`. +- **Files modified:** `crates/vector-render/src/pipeline.rs`, `crates/vector-render/tests/pipeline_init.rs` +- **Verification:** `cargo check -p vector-render` clean, `cargo test --workspace --tests` 55 passed / 0 failed; `cargo run -p vector-app --release` alive after 5s with clean exit on SIGTERM. +- **Committed in:** `eea4540` + +**2. [Rule 1 - Bug] `clippy::needless_pass_by_value` on `RenderContext::new(window: Arc)`** +- **Found during:** Task 2 (clippy pass) +- **Issue:** Inside the function the Arc is cloned exactly once (passed into `instance.create_surface`); clippy sees the original binding as un-consumed and demands a borrow. +- **Fix:** Changed signature to `pub fn new(window: &Arc) -> Result`; mirrored in `RenderHost::new`. `app.rs` now passes `&window` (the original Arc remains in `self.window`). +- **Files modified:** `crates/vector-render/src/pipeline.rs`, `crates/vector-app/src/render_host.rs`, `crates/vector-app/src/app.rs` +- **Verification:** `cargo clippy --workspace --all-targets -- -D warnings` clean. +- **Committed in:** `eea4540` + +**3. [Rule 1 - Bug] `clippy::ignore_without_reason` on every `#[ignore]` stub** +- **Found during:** Task 1 (clippy pass) +- **Issue:** Plan template prescribed bare `#[ignore]`, but the workspace's pedantic clippy lint group denies bare `#[ignore]` without a reason string. +- **Fix:** Replaced `#[ignore]` with `#[ignore = "Wave-0 stub"]` across all 20 stub files via `perl -i -pe`. +- **Files modified:** all 20 stub files listed in the Wave-0 Stub Map. +- **Verification:** `cargo clippy --workspace --all-targets -- -D warnings` clean. +- **Committed in:** `cd0159d` + +**4. [Rule 3 - Blocking] vector-render arch-lint `block_on` allowlist needs `pipeline.rs`** +- **Found during:** Task 2 (test pass) +- **Issue:** `crates/vector-render/tests/no_tokio_main.rs::forbidden_tokio_patterns_absent_from_src` panicked on `pollster::block_on(...)` calls in `pipeline.rs`. The lint has zero tolerance by default (`BLOCK_ON_ALLOWLIST: &[]`). wgpu requires synchronous-looking init on the macOS main thread. +- **Fix:** Added `"pipeline.rs"` to `BLOCK_ON_ALLOWLIST` with a comment explaining the wgpu-on-main-thread rationale. D-09 invariant (no PTY async on main thread) remains intact — these block_on calls are wgpu init, not PTY I/O. +- **Files modified:** `crates/vector-render/tests/no_tokio_main.rs` +- **Verification:** `cargo test -p vector-render --test no_tokio_main` passes; 15==15 arch-lint invariant holds. +- **Committed in:** `eea4540` + +**5. [Documentation drift, not a code change] Plan said "17 Wave-0 stubs" but `` list enumerated 20** +- **Found during:** Task 1 (file creation) +- **Issue:** Plan body references "17" in several places (objective, behavior, success_criteria), but the `` list and the action mapping table both enumerate 20 concrete paths. +- **Fix:** Shipped 20 stubs (the file list is the load-bearing source of truth; the "17" tokens are stale prose). Mapping table in this SUMMARY documents all 20. +- **Files modified:** N/A (no code change; documentation discrepancy) +- **Verification:** `find crates/{vector-render,vector-fonts,vector-input,vector-app}/tests -name '*.rs' -not -name 'no_tokio_main.rs' | wc -l` outputs 20. +- **Committed in:** `cd0159d` (mapping table preserved in this SUMMARY for Plan 03-02..05 reference) + +--- + +**Total deviations:** 4 code auto-fixes + 1 documentation discrepancy +**Impact on plan:** All four code fixes are correctness deviations (API drift, clippy gates, arch-lint gate). The "17 vs 20" doc drift required no code change; the 20 stubs all carry their owning Plan tag and are the working contract for downstream plans. No scope creep, no architectural changes (Rule 4 never triggered). + +## Issues Encountered + +None beyond the deviations above. The wgpu-on-main-thread / pollster pattern, the `Arc` lifetime hand-off, and the lock-feed-drop scope in `user_event` were prescribed by the plan and worked exactly as written once the wgpu 29 API drift was reconciled. + +## User Setup Required + +None — no external service configuration required. JetBrains Mono bundling and font-stack wiring lands in Plan 03-02; this plan paints a clear color only. + +## Hand-off Notes + +**Plan 03-02 (atlas):** `RenderContext` exposes `pub device: Device` and `pub queue: Queue`. The atlas crate should take a `&Device` + `&Queue` in its constructor and live alongside `RenderContext` inside `RenderHost`; do not duplicate the wgpu device. `crossfont 0.9` is at the workspace level — `vector-fonts/Cargo.toml` needs `crossfont.workspace = true`. The four font test stubs are live (Wave-0 Stub Map). + +**Plan 03-03 (compositor):** `Term::damage()` returns `alacritty_terminal::term::TermDamage<'_>`; iterate `Partial(TermDamageIterator<'_>)` yielding `LineDamageBounds { line, left, right }`. All three types are re-exported via `vector_term::*` so `vector-render` does NOT need a direct `alacritty_terminal` dep. The renderer should acquire the lock via `Arc>` (already shared between `App` and the I/O actor), iterate damage in a `{ }` scope, drop the lock, then encode draw calls. After successful submit, call `term.reset_damage()` inside a second tight lock scope. The cell snapshot strategy (collect rows under the lock vs. iterate while holding) is the compositor plan's call. Six test stubs are live (snapshot_clearcolor/singlecell/truecolor/damage_to_quads/cursor_overlay_snapshot + atlas_lru in vector-render). + +**Plan 03-04 (input):** `pty_actor.rs` currently only pumps reads. The plan's existing comment marker (`Plan 03-04 will add a write channel + biased select! for input`) is in the file. Wire-up steps: introduce a `mpsc::channel::>(64)` somewhere on the App side, pass the `Sender` into `App` (e.g., constructor parameter), pass the `Receiver` into `pty_actor::run` as a second argument, and turn the actor's body into a `biased; tokio::select! { reader.recv() => …, write_rx.recv() => transport.write(&bytes).await }`. Five input/render test stubs are live (xterm_key_table, bracketed_paste_wrap, selection_overlay_snapshot, selection_render, and the WIN-01-extension follow-on inside win_style_mask if a richer assertion ever lands). + +**Plan 03-05 (pacing + polish):** Four test stubs target this plan (dpr_change_invalidates, pty_coalesce, idle_no_redraw, frame_pacing). When you delete `tick.rs`, remove the `#[allow(dead_code)] mod tick;` line from `main.rs` and drop the `UserEvent::Tick(u64)` variant. The clear-color in `render_host.rs::render_clear_default` is the hand-off point for theme-uniformization (Claude's Discretion D-40). + +## Self-Check: PASSED + +- FOUND: `crates/vector-render/src/pipeline.rs` +- FOUND: `crates/vector-app/src/pty_actor.rs` +- FOUND: `crates/vector-app/src/render_host.rs` +- FOUND: `.planning/phases/03-gpu-renderer-first-paint/03-01-SUMMARY.md` +- FOUND commit `cd0159d` (Task 1) +- FOUND commit `eea4540` (Task 2) +- Wave-0 stub count: 20 (live on disk under `crates/{vector-render,vector-fonts,vector-input,vector-app}/tests/`) +- Arch-lint invariant: 15 `no_tokio_main.rs` files (unchanged from baseline) + +--- +*Phase: 03-gpu-renderer-first-paint* +*Completed: 2026-05-11* From 1976cecd99a508acc6cf9d57cfee16a32cf5c51f Mon Sep 17 00:00:00 2001 From: Ashutosh Tiwari Date: Mon, 11 May 2026 12:43:44 -0700 Subject: [PATCH 004/178] feat(03-02): crossfont rasterizer + bundled JetBrains Mono + unicode-width MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit -

Three auto-fixed code deviations: Rule 2 (hide-cursor `\x1b[?25l ... \x1b[?25h` bracketing each frame to kill the 30Hz strobe of cursor positioning), Rule 3 (best-effort raw mode — skip `enable_raw_mode()` when stdin isn't a tty so CI / `< /dev/null` smokes work), Rule 3 (added `alacritty_terminal` as direct binary-local dep for `Color`/`Cell`/`Point` types in `render.rs`; re-export via vector-term would have polluted that crate's public API). One documented-not-fixed shell-side behavior: zsh in `/dev/null` mode holds its prompt on lone EOT (acceptable per plan acceptance criteria — interactive smokes all exit cleanly with `exit` keystroke). Phase 2 closes; Phase 3 (GPU renderer) inherits the Term + PTY + transport plumbing untouched and only swaps `render.rs` for a wgpu glyph atlas (actor pattern, SharedTerm `Arc>`, SIGWINCH watcher, scopeguard discipline all carry forward). - **Phase 2 Plan 04 (Wave 3) complete (2026-05-11):** `vector-mux` ships `PtyTransport` + `Domain` traits in their FINAL D-38 shape (`async_trait` boxed futures; `Send + 'static` / `Send + Sync` respectively). `LocalDomain` fully implemented: `$SHELL` → `/etc/passwd` (keyed by `id -un`) → `/bin/zsh` → `/bin/bash` resolution chain; `LocalDomain::spawn(SpawnCommand)` returns `Box` wrapping `LocalPty` via the `LocalTransport` newtype (the newtype lives in vector-mux, NOT in vector-pty, to avoid a vector-pty → vector-mux dep cycle while keeping the trait surface in the consumer crate per D-38). `CodespaceDomain::spawn` `unimplemented!("Phase 7")`; `DevTunnelDomain::spawn` `unimplemented!("Phase 8")`; both `reconnect` bodies `unimplemented!("Phase 9: Persistence + reconnect")`. 8 tests pass: 2 compile-time object-safety, 3 label/alive, 2 should_panic phase markers, and **1 end-to-end CORE-04/05 reachability proof** (`LocalDomain::spawn` of `sh -c "echo hi"` through `Box` collects "hi" via `take_reader()` and gets `Ok(Some(0))` from `wait()` — proving the trait surface, not just direct LocalPty, carries CORE-04 clean-exit and CORE-05 TERM env). One surface change in vector-pty: `LocalPty::write(&self)` → `LocalPty::write(&mut self)` (Rule 3 blocking fix — `Box` is `!Sync` so the trait-object Send-future bound forced `&mut self` borrow; no vector-pty caller invokes `.write` in Plan 02-03's tests so the change is zero-risk to existing contracts). Two task commits: b88a02d + c0ad634. Four auto-fixed deviations: 1 Rule 3 (LocalPty::write signature) + 3 Rule 1 (clippy `no_effect_underscore_binding`, `while_let_loop`, rustfmt long-line wrapping). - **Phase 2 Plan 02 (Wave 1) complete (2026-05-11):** `vector-term` ships its full public API — `Term::new/feed/resize/grid/cursor/mode/dims/search` + `Match` struct — backed by `alacritty_terminal 0.26`. 26 conformance tests pass in 0.34s wall-clock (D-37 budget was 1s). CORE-01 (CSI/OSC/DCS/partial-UTF-8/alt-screen-1049/DECSTBM/ED/EL), CORE-02 (24-bit + 256-color SGR via `Color::Spec(Rgb)` / `Color::Indexed(u8)` + CJK/emoji-ZWJ `WIDE_CHAR + WIDE_CHAR_SPACER` flags), CORE-03 (10k+ scrollback regex via streaming `RegexSearch`+`RegexIter`, ~150ms — Pitfall 7 honored), CORE-06 (BRACKETED_PASTE + MOUSE_REPORT_CLICK + SGR_MOUSE bit toggles) all covered. search.rs ships with Task 1 (c4bb201) because the ED-2-vs-scrollback test consumes it; Task 2 (5a1fc48) lands CORE-02/03 fixtures. Four auto-fixed deviations (clippy cast lints + manual_let_else + rustfmt assert wrap + the discovery that `\b` doesn't fire in regex_automata's hybrid DFA — substring patterns are our search contract). No `unsafe`, no `from_utf8` in feed path (Pitfall 4), no string materialization in search (Pitfall 7). `_api_probe` retired; the real wrapper is now the load-bearing compile check. +- **Phase 3 Plan 02 (Wave 2) complete (2026-05-11):** `vector-fonts` ships `FontStack::load_bundled/rasterize` over crossfont 0.9 CoreText with bundled JetBrains Mono Regular TTF (270,224 bytes, OFL 1.1) + OFL license shipped via cargo-bundle `[package.metadata.bundle].resources`.

We expand the 3-channel CoreText alphamask to RGBA at upload (alpha = max(r,g,b)); shader will multiply sampled `.rgb` by foreground color.

CoreText's rasterizer-per-pixel-grid produces the same effective pixel density. +- **Files modified:** `crates/vector-fonts/src/loader.rs` +- **Verification:** `cargo test -p vector-fonts --test crossfont_load_bundled` passes; the test confirms a non-zero-size glyph rasterizes. +- **Committed in:** `1976cec` + +**2.

[Rule 1 - Bug] 128×128 test atlas was too large to force LRU eviction** +- **Found during:** Task 2 (atlas_lru integration test panic) +- **Issue:** Plan prescribed `Atlas::new_with_dims(&device, 128, 128)` for the eviction test. At 14 pt, ASCII glyphs are ~9×17 px; 94 chars × 153 px² ≈ 14.4 k px², well below 128² = 16.4 k px². Even with shelf packing waste, 'A'-through-'~' fits without forcing eviction, so the assertion that `!` had been evicted failed. +- **Fix:** Shrunk to `64×64` (4096 px² capacity) so eviction is mandatory after ~24 glyphs. Test now confirms '!' evicted and '~' resident. +- **Files modified:** `crates/vector-render/tests/atlas_lru.rs` +- **Verification:** `cargo test -p vector-render --test atlas_lru` passes deterministically across 3 consecutive runs. +- **Committed in:** `9dd4208` + +**4. [Rule 1 - Bug] clippy pedantic cast lints on metrics rounding (`cast_sign_loss`, `cast_possible_truncation`)** +- **Found during:** Task 1 (clippy pass) +- **Issue:** Workspace `pedantic` warns on `metrics.average_advance.round().max(1.0) as u32` (`cast_sign_loss`) and `metrics.descent.round() as i32` (`cast_possible_truncation`). The values are clamped to safe ranges in the original code, but the lint can't see through `.round()`. +- **Fix:** Extracted to helper functions `f_to_u32` (clamp to `[1.0, u32::MAX]`) and `f_to_i32` (clamp to `[i32::MIN, i32::MAX]`) with scoped `#[allow]` attributes on each.

No scope creep. + +**Impact on plan:** Two were API drift between the plan's reproduced snippets and reality (crossfont 0.9 `new()` signature; wgpu 29 `TexelCopy*` rename). One was a test-fixture sizing bug (128×128 too large to force LRU eviction). Four were clippy `-D warnings` lint compliance fixes on top of the plan's verbatim code. Plan's behavioral contract (RENDER-04, D-40, D-41, D-43, D-50, Pitfall 2) is met exactly. + +## Issues Encountered + +None beyond the deviations above. crossfont's CoreText fallback chain delivered Apple Color Emoji for `🦀` without any user-facing configuration — the `two_atlas_split` test passes on the first run. etagere's shelf packing is deterministic at fixed input sizes, so the LRU eviction test is reproducible. + +## User Setup Required + +None. JetBrains Mono is bundled at build time (cargo-bundle for production .app; dev workspace path for `cargo run` / `cargo test`); no system-level font installation required. + +**Pitfall 7 / Open Question #3 cargo-bundle subdirectory preservation:** The `resources = ["resources/Fonts/JetBrainsMono-Regular.ttf", "resources/Fonts/LICENSE-JetBrainsMono.txt"]` array passes the full sub-path. cargo-bundle 0.10's documented behavior is to copy each entry to `Vector.app/Contents/Resources/` — i.e., the `Fonts/` subdirectory **may not be preserved** in the bundled `.app`. This is **NOT a CI gate** for Plan 03-02; it surfaces in Plan 03-05's manual DMG smoke matrix (Task 2, item #1: "vim renders correctly with visible cursor in a real window"). If the subdir is flattened, our `locate_bundled_font` resolver's bundle-path branch (`.join("Resources").join("Fonts").join(...)`) will miss and fall back to the dev path — which is empty in a shipped .app, triggering the `JetBrains Mono not found` error. Mitigation if needed: post-process step in `xtask::dmg` to move `Vector.app/Contents/Resources/JetBrainsMono-Regular.ttf` into a `Fonts/` subdir, OR change `locate_bundled_font` to also try `Resources/JetBrainsMono-Regular.ttf` (flat). Recommend the latter — one extra path probe, no xtask change. Documented here so Plan 03-05's smoke matrix can flag it cleanly. + +## Hand-off Notes + +**Plan 03-03 (compositor):** +- `Atlas::slot_for(&queue, key, &glyph) -> AtlasSlot` is the call site. The compositor builds a `GlyphKey { character, dpr_bucket }` (dpr_bucket = round(scale_factor) as u8 typically), rasterizes via `FontStack::rasterize(c)` to get a `RasterizedGlyph`, then passes both to `slot_for`. Cache hits return `AtlasSlot::{Mono,Color}` with UVs + size + offset; cache misses upload and return the same. +- `mono_view()` / `color_view()` are the bind-group source views for the cell shader. Both are `Rgba8Unorm`. The cell shader should sample with linear filtering (sampler in Plan 03-03's responsibility), multiply `.rgb` by the fg color for mono samples, and use `.rgba` directly for color samples. The shader needs a way to know which atlas to sample — Plan 03-03 will likely encode it as a vertex attribute (e.g., `atlas_kind: u32` in the quad vertex). +- `AtlasSlot::Fallback` indicates the glyph is too large to fit even an empty atlas (≥ 2048 px in either dimension — unlikely for a terminal font but defensible). Compositor should render a tofu box for these. +- Atlas is `!Sync` (wgpu types are `Sync` but `HashMap<_,_>` mutation through `&mut self` makes the whole struct exclusive). Put it in the same render-thread location as `RenderContext`; do NOT share it with the I/O thread. + +**Plan 03-05 (DPR change + polish):** +- `Atlas::clear_all()` is the lever for `ScaleFactorChanged` (D-48). It rebuilds both `AtlasAllocator`s, clears both slot maps, and clears both LRU queues. Compositor's next-frame glyph lookups will all miss and re-rasterize at the new DPR. Acceptable one-frame stutter per success criterion #4. +- `FontStack::load_bundled(new_dpr, size_pt)` should be called alongside `clear_all` to reload metrics at the new pixel grid; the per-frame `rasterize` calls flow through normally. +- DMG smoke matrix item #1 will catch any cargo-bundle subdir flattening (see "User Setup Required" above). + +**Plan 04 (mux):** +- Atlas state is per-render-context. If Phase 4 introduces multiple windows, each window's `RenderHost` should have its own `Atlas` instance (atlases share the wgpu `Device` but not the `Texture`/slot state). + +## Self-Check: PASSED + +- FOUND: `crates/vector-fonts/src/glyph.rs` +- FOUND: `crates/vector-fonts/src/loader.rs` +- FOUND: `crates/vector-fonts/src/width.rs` +- FOUND: `crates/vector-render/src/atlas.rs` +- FOUND: `crates/vector-app/resources/Fonts/JetBrainsMono-Regular.ttf` (270,224 bytes) +- FOUND: `crates/vector-app/resources/Fonts/LICENSE-JetBrainsMono.txt` (4399 bytes) +- FOUND commit `1976cec` (Task 1: vector-fonts + bundled TTF) +- FOUND commit `9dd4208` (Task 2: Atlas + LRU) +- 5 Wave-0 stubs un-ignored and passing (3 crossfont/grayscale/two-atlas in vector-fonts, atlas_lru_eviction with 2 sub-tests, atlas_lru in vector-render) +- 13 Wave-0 stubs still ignored (owned by Plans 03-03/03-04/03-05) +- Arch-lint: 15 `no_tokio_main.rs` files (unchanged from baseline; 15==15 holds) +- Workspace: 61 passed / 0 failed / 13 ignored + +--- +*Phase: 03-gpu-renderer-first-paint* +*Completed: 2026-05-11* From 9101e291226ea872508a997cc9fafd7a9e8bebf4 Mon Sep 17 00:00:00 2001 From: Ashutosh Tiwari Date: Mon, 11 May 2026 13:01:32 -0700 Subject: [PATCH 007/178] feat(03-03): cell pipeline + Compositor::render reading Term::damage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - CellInstance (Pod, 80 bytes) + CellPipeline (instanced quad, 2-atlas bind group, uniforms) - cell.wgsl: mono multiplies fg by RGB alphamask; color samples directly; per-cell selected bit blends to selection_tint - Compositor::new/render(selection: Option<((u16,u16),(u16,u16))>) — selection arg from day one (Plan 03-04 populates) - xterm-256 palette (16 ANSI + 6x6x6 cube + 24-step ramp) embedded; color_to_rgba covers Named/Spec(Rgb)/Indexed - WIDE_CHAR_SPACER cells skipped (Pitfall 4) - term.damage() snapshot + reset_damage() under one scope; Term lock dropped before GPU work (D-11) - CompositorError {Outdated, Lost, Timeout, Validation} replaces wgpu 29's removed SurfaceError - Plumbing tests un-ignored: damage_to_quads, snapshot_singlecell, snapshot_truecolor (pixel asserts land in Task 2) - fixtures dir seeded for future PNG fixtures --- Cargo.lock | 1 + crates/vector-render/Cargo.toml | 4 + crates/vector-render/src/cell_pipeline.rs | 363 +++++++++++++++ crates/vector-render/src/compositor.rs | 428 ++++++++++++++++++ crates/vector-render/src/lib.rs | 4 + crates/vector-render/src/shaders/cell.wgsl | 75 +++ crates/vector-render/tests/damage_to_quads.rs | 16 +- crates/vector-render/tests/fixtures/.gitkeep | 0 .../tests/snapshot_singlecell.rs | 16 +- .../vector-render/tests/snapshot_truecolor.rs | 23 +- 10 files changed, 915 insertions(+), 15 deletions(-) create mode 100644 crates/vector-render/src/cell_pipeline.rs create mode 100644 crates/vector-render/src/compositor.rs create mode 100644 crates/vector-render/src/shaders/cell.wgsl create mode 100644 crates/vector-render/tests/fixtures/.gitkeep diff --git a/Cargo.lock b/Cargo.lock index fb5838c..795415b 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -2322,6 +2322,7 @@ dependencies = [ name = "vector-render" version = "2026.5.10" dependencies = [ + "alacritty_terminal", "anyhow", "bytemuck", "etagere", diff --git a/crates/vector-render/Cargo.toml b/crates/vector-render/Cargo.toml index 52954c4..a24e44b 100644 --- a/crates/vector-render/Cargo.toml +++ b/crates/vector-render/Cargo.toml @@ -7,6 +7,7 @@ license.workspace = true description = "GPU pipeline, glyph atlas, damage tracking — Phase 3 (wgpu, Metal)."

One surface change in vector-pty: `LocalPty::write(&self)` → `LocalPty::write(&mut self)` (Rule 3 blocking fix — `Box` is `!Sync` so the trait-object Send-future bound forced `&mut self` borrow; no vector-pty caller invokes `.write` in Plan 02-03's tests so the change is zero-risk to existing contracts).

Pitfall 4 honored: `Flags::WIDE_CHAR_SPACER` cells skipped (lead cell paints the wide glyph in its own cell rectangle for v1; widening to a 2-cell quad is a Phase 4+ improvement). +- **24-bit truecolor + 256-color paths.** `color_to_rgba` maps `Color::Spec(Rgb { r, g, b }) → [r/255, g/255, b/255, 1.0]`, `Color::Indexed(i) → palette_256[i]`, and `Color::Named(NamedColor)` → palette index or `default_fg`/`default_bg`. The xterm-256 palette is built once at compositor construction (`xterm_256_palette() -> [[f32; 4]; 256]`) — 16 ANSI base + 6×6×6 cube + 24-step grayscale ramp, well-known table cited inline. +- **`Compositor::render_offscreen` + `render_offscreen_with`** ship a surface-free render path for snapshot tests.

WGSL instance buffers don't require std140-style 16-byte padding; naga validates the layout against our shader's `@location` declarations and accepts 72. Compile-time `const _: () = assert!(size_of::() == 72);` guards future drift. +- **`xterm_256_palette()` is `Source: xterm 256-color palette` (en.wikipedia.org/wiki/ANSI_escape_code#8-bit; verified against xterm git refs).** 16 ANSI base colors (Black .. BrightWhite — xterm's `cd 00 00` / `e5 e5 e5` family), 6×6×6 cube starting at index 16 (`CUBE_STEPS = [0, 95, 135, 175, 215, 255]`), 24-step grayscale ramp at 232 (`v = 8 + 10·i`). All values cited inline in the function. +- **Selection arg in `Compositor::render` from day one.** Plan 03-04's selection state machine will populate the `Option<((u16,u16),(u16,u16))>` argument; Plan 03-03 callers (app.rs RedrawRequested + the 5 snapshot tests) pass `None`. No signature drift between phases. `is_cell_selected(selection, col, row)` is the helper that maps a row-major bounding box to per-cell hit-testing; selection is inclusive on both endpoints. +- **`CompositorError` replaces wgpu's removed `SurfaceError`.** wgpu 29 returns the `CurrentSurfaceTexture` enum from `Surface::get_current_texture()` rather than `Result<_, SurfaceError>`. We pattern-match it into our local `CompositorError { Outdated, Lost, Timeout, Validation }` so downstream callers (RenderHost, future Phase 4 mux) get a stable type regardless of wgpu's status-renaming churn. +- **Outdated/Lost auto-recovery happens inside Compositor::render.** `Surface::get_current_texture()` returning `Outdated`|`Lost` triggers `surface.configure(&device, &config)` then the Compositor returns the error variant. RenderHost::render's `match` swallows both via `Ok(()) | Err(Outdated|Lost) => Ok(())`. Next RedrawRequested retries cleanly. +- **`clippy::await_holding_lock = "deny"` holds at compile time.** `app.rs::RedrawRequested` has zero `.await` between `let mut t = self.term.lock();` and the end of the arm — the entire render path is synchronous (wgpu submits + presents synchronously; the device.poll in `render_offscreen_with` is in tests, not the live render path). +- **Cursor blink rate decision: always-on block cursor in Plan 03-03.** Per CONTEXT.md "Claude's Discretion — Cursor visuals: block style is conventional; blink rate matches macOS default if simple, otherwise pick a fixed rate (e.g., 530 ms half-period) and move on." Blink + cursor color in a theme uniform both deferred to Plan 03-05 per the Cursor Visuals discretion clause. +- **Test path bypasses winit.** Initial approach tried `EventLoop::create_window` from a test thread, but winit's macOS `Window` requires main-thread construction and tests run in a thread pool. Solution: `RenderContext::new_offscreen` requests a Metal adapter with `compatible_surface: None`; tests build Compositor via `new_with` and render via `render_offscreen_with`.

Actual `[u32; 2] + [f32; 4]×3 + u32×4` packs to 72 bytes with no internal padding because all fields are 4-byte-aligned scalars/arrays. WGSL instance buffers don't require 16-byte stride padding; naga accepts 72. +- **Fix:** Corrected the doc comment ("72 bytes per instance") and replaced the silent `let _ = [(); size_of % 16];` with a real `const _: () = assert!(size_of::() == 72);` that fails the build if the layout ever drifts. +- **Files modified:** `crates/vector-render/src/cell_pipeline.rs`, `crates/vector-render/src/compositor.rs` +- **Verification:** `cargo build -p vector-render` clean; assertion is enforced. +- **Committed in:** `b35ffad` + +**4.

The wgpu 29 API surface required mechanical translation from the plan snippets; the offscreen test harness required a small constructor addition (`new_offscreen` + `new_with`) to skip winit.

The compositor uses the bundled JetBrains Mono from Plan 03-02; no external configuration required. + +## Hand-off Notes + +**Plan 03-04 (input):** +- `Compositor::render` signature already takes `selection: Option<((u16, u16), (u16, u16))>` — Plan 03-04 populates this from the selection state machine. `((col_anchor, row_anchor), (col_cursor, row_cursor))` is the contract; `is_cell_selected` does the row-major inclusive bounding box check (anchor ≤ cell ≤ cursor in (row, col) lex order, swapping if necessary). +- `selection_overlay_snapshot.rs` is still `#[ignore = "Wave-0 stub"]`. Plan 03-04 fills it once it has a selection range — pattern matches the other snapshot tests (`offscreen::build_compositor`, render with selection populated, assert tint-shifted pixels at the selected cell rectangle). +- `vector-app/src/app.rs::WindowEvent::RedrawRequested` passes `None` for selection. Plan 03-04 replaces that with `self.input_bridge.selection.range().map(|r| (r.anchor, r.cursor))` (or whatever shape the input crate ships). +- The CellInstance shader inputs include a `flags: u32` field (bit 0 = inverse, bit 1 = bold reserved).

Plan 03-05 toggles between the lit color and the bg color on a 530 ms half-period (or matches macOS's blink rate via NSUserDefaults). +- Damage-driven partial buffer rewrites: `prepare_frame_raw` snapshots damage into `_damage_rows: Vec<(u16, u16, u16)>` but currently does a full rebuild.

`Send + 'static` / `Send + Sync` respectively). `LocalDomain` fully implemented: `$SHELL` → `/etc/passwd` (keyed by `id -un`) → `/bin/zsh` → `/bin/bash` resolution chain; `LocalDomain::spawn(SpawnCommand)` returns `Box` wrapping `LocalPty` via the `LocalTransport` newtype (the newtype lives in vector-mux, NOT in vector-pty, to avoid a vector-pty → vector-mux dep cycle while keeping the trait surface in the consumer crate per D-38). `CodespaceDomain::spawn` `unimplemented!("Phase 7")`; `DevTunnelDomain::spawn` `unimplemented!("Phase 8")`; both `reconnect` bodies `unimplemented!("Phase 9: Persistence + reconnect")`. 8 tests pass: 2 compile-time object-safety, 3 label/alive, 2 should_panic phase markers, and **1 end-to-end CORE-04/05 reachability proof** (`LocalDomain::spawn` of `sh -c "echo hi"` through `Box` collects "hi" via `take_reader()` and gets `Ok(Some(0))` from `wait()` — proving the trait surface, not just direct LocalPty, carries CORE-04 clean-exit and CORE-05 TERM env). One surface change in vector-pty: `LocalPty::write(&self)` → `LocalPty::write(&mut self)` (Rule 3 blocking fix — `Box` is `!Sync` so the trait-object Send-future bound forced `&mut self` borrow; no vector-pty caller invokes `.write` in Plan 02-03's tests so the change is zero-risk to existing contracts). Two task commits: b88a02d + c0ad634.

Four auto-fixed deviations (clippy cast lints + manual_let_else + rustfmt assert wrap + the discovery that `\b` doesn't fire in regex_automata's hybrid DFA — substring patterns are our search contract).

Resize prioritized per Plan 02-05 hand-off (SIGWINCH starvation avoided). +- `UserEvent::Resized { rows, cols }` round-trips: window resize → mpsc → actor calls `transport.resize` → proxy sends `UserEvent::Resized` back → main locks `Term`, resizes grid. +- App handles `ModifiersChanged`, `KeyboardInput` (encode → write_tx), `MouseInput Left` (selection mouse_down/up), `CursorMoved` (drag mouse_move + redraw), `MouseWheel` (logged, deferred to Plan 03-05), `Resized` (cell-metric-driven cols/rows propagation). +- `Cmd-V` reads the macOS pasteboard via `NSPasteboard::generalPasteboard().stringForType(NSPasteboardTypeString)` and wraps via `wrap_bracketed_paste`. +- `Compositor` per-cell `selected` flag now derives from a row-major selection contract (was a bounding box in Plan 03-03). +- `selection_render` (vector-app) un-ignored: 6 contract tests for `SelectionState` transitions and `SelectionRange::cells`. +- `selection_overlay_snapshot` (vector-render) un-ignored: pixel-readback asserts the blue selection tint dominates red and out-blues unselected cells. + +## Task Commits + +1. **Task 1: vector-input — keymap + paste + selection types + tests** — `fc506e7` (feat) +2. **Task 2: wire vector-input into vector-app + compositor + tests** — `6aac789` (feat) + +## Files Created/Modified + +- `crates/vector-input/src/keymap.rs` — `encode_key` + test-friendly `encode` core +- `crates/vector-input/src/mods.rs` — `ModState` from `winit::ModifiersState` +- `crates/vector-input/src/paste.rs` — `wrap_bracketed_paste` with CR/LF normalization +- `crates/vector-input/src/selection.rs` — `SelectionRange` + `SelectionState` +- `crates/vector-input/Cargo.toml` — added `winit.workspace = true` +- `crates/vector-input/src/lib.rs` — exports +- `crates/vector-input/tests/xterm_key_table.rs` — 86 test cases (was Wave-0 stub) +- `crates/vector-input/tests/bracketed_paste_wrap.rs` — 4 test cases (was Wave-0 stub) +- `crates/vector-app/Cargo.toml` — added `vector-input = { path = "../vector-input" }` +- `crates/vector-app/src/input_bridge.rs` — `InputBridge { selection, write_tx, resize_tx }` +- `crates/vector-app/src/app.rs` — full input pipeline + clipboard read + cell-from-pixel +- `crates/vector-app/src/main.rs` — `UserEvent::Resized`, mpsc channels, `App::new(write_tx, resize_tx)` +- `crates/vector-app/src/pty_actor.rs` — biased `tokio::select!` over resize/write/read +- `crates/vector-app/src/render_host.rs` — added `cell_metrics_px(&self)` +- `crates/vector-render/src/compositor.rs` — `is_cell_selected` rewritten to row-major +- `crates/vector-render/tests/selection_overlay_snapshot.rs` — pixel-readback assertion (was Wave-0 stub) +- `crates/vector-app/tests/selection_render.rs` — 6 contract tests (was Wave-0 stub) + +## Decisions Made + +- **`encode` core alongside `encode_key`.** `winit::event::KeyEvent` has a private `platform_specific` field, so unit tests can't construct it via struct literal. Solution: expose `encode(&Key, Option<&str>, ElementState, ModState) -> Option>` as the test entry point, with `encode_key(&KeyEvent, ModState)` as a one-line forwarder. The 86 keymap tests call `encode` directly. +- **Row-major selection contract.** `SelectionRange::cells` (in vector-input) and `is_cell_selected` (in vector-render) both implement: partial first row from anchor to EOL → all intervening rows full-width → partial last row from BOL to cursor. Matches macOS Terminal / iTerm selection feel. Single-row selections degenerate to anchor..=cursor (column range). +- **Compositor stays vector-input-free.** Mirroring the row-major logic inline in `compositor.rs` keeps the dep graph flat. Documented in a comment near `is_cell_selected`. +- **Scroll wheel deferred to Plan 03-05.** `vector-term` doesn't expose `Term::scroll_display` (alacritty's `Term` has it but our wrapper doesn't surface it). Both `MouseScrollDelta::LineDelta` and `PixelDelta` arms log at `tracing::debug` and return. Plan 03-05 ratifies the surface + wiring. +- **Drop-on-full write channel.** `mpsc::Sender::try_send` for both keystroke bytes and resize events — main thread never blocks. Channel sized 64 (writes) / 8 (resizes) — generous given typical typing cadence; warn-logged on full. +- **Cmd is not an xterm modifier.** `ModState::xterm_mod_param` only mixes Shift/Alt/Ctrl. Cmd routes to app shortcuts (Cmd-V handled in `app.rs`; Cmd-C deferred per D-53; Cmd-W via menu). + +## Deviations from Plan + +### Auto-fixed Issues + +**1. [Rule 3 - Blocking] winit 0.30 KeyEvent has a private field — tests can't struct-literal it** +- **Found during:** Task 1 (xterm_key_table.rs initial build) +- **Issue:** `KeyEvent { physical_key, logical_key, text, location, state, repeat }` failed to compile because `platform_specific: KeyEventExtra` is `pub(crate)`. The plan's test scaffold assumed construction via struct literal. +- **Fix:** Split the encoder into `encode_key(&KeyEvent, ModState)` (production) + `encode(&Key, Option<&str>, ElementState, ModState)` (test-friendly). Tests now call `encode` directly with two helpers `named(NamedKey, ModState)` and `ch(&str, ModState)`. Behavior is identical — `encode_key` just unpacks the KeyEvent fields and forwards. +- **Files modified:** `crates/vector-input/src/keymap.rs`, `crates/vector-input/src/lib.rs`, `crates/vector-input/tests/xterm_key_table.rs` +- **Verification:** 86 tests pass; `encode_key` is still used live in `vector-app::app.rs::WindowEvent::KeyboardInput`. +- **Committed in:** `fc506e7` + +**2. [Rule 2 - Missing Critical] Plan-03-03 selection contract was a bounding box; rewrote to row-major** +- **Found during:** Task 2 (Compositor signature already had `selection: Option<((u16,u16),(u16,u16))>` from Plan 03-03; its `is_cell_selected` was rectangular) +- **Issue:** The Plan 03-04 `SelectionRange::cells` (and the user expectation per D-54) is row-major: partial first row, full middle rows, partial last row. Plan 03-03's bounding box would highlight a rectangle in the middle of multi-row selections — wrong shape, confusing visual. +- **Fix:** Replaced `is_cell_selected` body in `compositor.rs` with a row-major test that mirrors `SelectionRange::cells`. Added a comment noting the intentional duplication (avoids a vector-render → vector-input dep edge). +- **Files modified:** `crates/vector-render/src/compositor.rs` +- **Verification:** `selection_overlay_snapshot` test passes (selected cell blue dominates unselected cell blue + red); single-row + multi-row contract tests pass in `selection_render`. +- **Committed in:** `6aac789` + +**3. [Rule 3 - Blocking] Clippy `cast_possible_truncation` + `cast_sign_loss` on f64→u32→u16** +- **Found during:** Task 2 (workspace clippy) +- **Issue:** `cell_from_pixel` converts `PhysicalPosition` to u16 cell coords; the f64→u32 cast tripped two pedantic lints. +- **Fix:** Added `#[allow(clippy::cast_possible_truncation, clippy::cast_sign_loss)]` at the cast sites; clamped negatives to 0 and capped at `u32::MAX` first; final u16 conversion via `u16::try_from(...).unwrap_or(u16::MAX)`. +- **Files modified:** `crates/vector-app/src/app.rs` +- **Verification:** `cargo clippy --workspace --all-targets -- -D warnings` exits 0. +- **Committed in:** `6aac789` + +**4. [Rule 2 - Missing Critical] `struct_excessive_bools` lint on `ModState`** +- **Found during:** Task 1 (clippy) +- **Issue:** `ModState { shift, alt, ctrl, cmd: bool }` has 4 bools — `clippy::struct_excessive_bools` triggers at 3+. +- **Fix:** `#[allow(clippy::struct_excessive_bools)]` on the struct with a comment "4 modifier flags maps 1:1 to xterm mod_param" — the bit-flag alternative would not improve clarity at this layer. +- **Files modified:** `crates/vector-input/src/mods.rs` +- **Verification:** `cargo clippy -p vector-input --all-targets -- -D warnings` exits 0. +- **Committed in:** `fc506e7` + +--- + +**Total deviations:** 4 auto-fixed (1 Rule 2 missing-critical [selection contract], 1 Rule 2 missing-critical [lint config], 2 Rule 3 blocking [winit private field + clippy casts]) +**Impact on plan:** Deviation 2 (row-major selection) corrects an inconsistency between Plan 03-03 and 03-04 contracts; both selection_overlay_snapshot and the contract tests now pass. The other three are minor build-fix shims. + +## Issues Encountered + +- `vector-term::Term::scroll_display` is not exposed in the wrapper; scroll-wheel wiring deferred to Plan 03-05 with a `tracing::debug` placeholder.

Throttle if needed. +- **Cursor blink:** add a half-period timer (530 ms default) firing a `UserEvent::CursorBlink`; cursor pipeline already has the visibility input. +- **LPM throttle:** detect `NSProcessInfo.lowPowerModeEnabled` + `processInfoPowerStateDidChange`; cap render ticks at 30 fps; trace-log activations (D-46). +- **DPR atlas clear:** on `ScaleFactorChanged` clear `Compositor::atlas_mut()` and let the next frame lazily re-rasterize (D-48). +- **First-paint timing gate (D-51):** drop the Phase 1 overlay only after shell-spawn + first PTY read + font loaded + first row dirty.

Focus routes spatially between split panes via Cmd-Opt-Arrow. The `Domain / Pane / PtyTransport` seam is the only contract between terminal model and transport — Phases 7/8/9 will plug remote transports into the same shape with zero changes to `vector-term`. + +**Covers requirements:** WIN-02, WIN-03, WIN-04 + +**Explicitly out of phase (deferred):** +- Cmd-N multi-window → Phase 5 +- Layout save/restore, broadcast-input, leader-key chord motion → Pitfall 21 scope guard, **not in v1 at all** +- OSC 7 cwd tracking (used as canonical cwd source for inheritance) → Phase 5; Phase 4 ships `proc_pidinfo` fallback +- Cmd-F search overlay → Phase 5 +- Cmd-C copy + selection-to-string → Phase 5 +- Mouse-reporting modes (DEC 1006/1015/1016 → PTY) → Phase 5 +- Remote tab tint + remote badge (CS-06) → Phase 7; Phase 4 ships Unicode-prefix scaffolding only + + + + +## Implementation Decisions + +### Tab bar style + +- **D-56:** **Native `NSWindowTabbingMode.preferred`.** One `NSWindow` per tab; AppKit groups them into the system-drawn tab bar at the top of the title bar. Matches Apple Terminal and ghostty. Far less code than a custom wgpu-drawn bar; CLAUDE.md "Stack Patterns by Variant" explicitly recommends this approach. WezTerm's hand-drawn bar is overkill for v1 macOS-only. The trade — the bar's appearance is whatever macOS chooses, no custom theming — is acceptable. + +- **D-57:** **Tab title = foreground process name, tracked dynamically.** Each pane tracks its PTY's foreground process group (`tcgetpgrp` on the master fd) → resolves to a process name via `proc_pidpath` / `comm`. Tab title updates as the user runs commands (e.g., `zsh` → `vim` → `zsh`). Matches Apple Terminal default. The Phase 1 menu bar stays installed once; key/menu events route to whichever NSWindow AppKit reports as `keyWindow`. + +- **D-58:** **CS-06 remote-tab differentiation = plan as Unicode-prefix; revisit in Phase 7.** Phase 4 leaves a hook (the Tab title is derived from `Domain.label() + ": " + foreground_process` — currently always `Local: vim`-style), so Phase 7 can produce `☁ codespace-name: vim` titles purely via string composition. No AppKit accessoryView plumbing in Phase 4. If pure-text proves insufficient in Phase 7, that's Phase 7's call. + +### Focus + split keymap + close semantics + +- **D-59:** **Cmd-Opt-Arrow for directional pane focus.** Cmd-Opt-Left / Right / Up / Down moves focus to the spatial neighbor across split boundaries. Matches ghostty + iTerm2. No Cmd-[/] cycle alternative (avoid keymap doubling, avoid Cmd-[ conflicts with vim-in-pane). Recursive binary split tree traversal: from a Leaf, find the nearest ancestor split in the right direction, descend the opposite child. + +- **D-60:** **Pane resize = mouse drag on divider + Cmd-Shift-Arrow keyboard nudge.** Drag the divider line for visual resize; Cmd-Shift-Left/Right shrinks/grows the active pane's horizontal axis in 1-cell increments; Cmd-Shift-Up/Down does vertical. Stored as cell-ratio (not pixels) in the split node so window resize preserves proportions. + +- **D-61:** **Cmd-W = close pane → fallback to close tab → fallback to close window → fallback to quit app.** Ghostty-style cascade. Implementation: `Cmd-W` always targets the focused pane; if that pane is the only Leaf in its Tab, close the Tab; if the Tab is the only Tab in the Window, close the Window; if the Window is the only one, terminate the app (matches existing Cmd-Q semantics from D-15). No separate Cmd-Shift-W. + +- **D-62:** **Tab cycling = Cmd-Shift-]/[ as specified in ROADMAP.** Standard macOS browser-style cycling. Goes through the AppKit-managed tab group order. No Cmd-1..9 jump-to-tab in v1. + +### Split cwd inheritance + +- **D-63:** **Inherit cwd via `proc_pidinfo(pid, PROC_PIDVNODEPATHINFO, ...)` for both Cmd-D split and Cmd-T new tab.** macOS libproc API (already on every Mac via the system libSystem; no new dep needed beyond a small FFI binding or the `libproc` crate). Resolve the active pane's shell PID's working directory and set it as the new pane's `SpawnCommand.cwd`. When OSC 7 lands in Phase 5, swap the inheritance source from proc_pidinfo to the OSC-7-reported cwd (more accurate — it tracks user-visible `cd` even when foreground proc is e.g. vim). + +- **D-64:** **Cwd inheritance fallback chain.** If `proc_pidinfo` fails (zombie shell, permissions edge case, child died mid-split): fall back to `$HOME` and trace-log the failure. Symlinks: take whatever proc_pidinfo returns (resolved, not the symlink path) — matches tmux behavior. No special handling for SIP-protected directories — if the shell ran from one, the new pane will too via inheritance. + +### Multi-window scope guard + +- **D-65:** **Cmd-N (new window) is DEFERRED to Phase 5.** The File menu keeps "New Window" disabled. The Mux singleton must support multiple `Window`s internally regardless (native NSWindowTabbingMode is implemented by AppKit as N grouped NSWindows), so the architecture is in place — only the user-facing shortcut is gated. Phase 5 wires up Cmd-N as part of broader polish. + +### Active-pane indicator + +- **D-66:** **Thin colored border on the focused pane.** 1–2 px border in an accent color around the active pane. Reuse Phase 3's per-cell tint uniform with a border-only mask (cheap — no new pipeline). Matches ghostty / iTerm2 default. No dimming of inactive panes (Phase 3's selection_tint is already used for selection; reuse it for the border but with a different uniform binding). + +### Mux architecture (Claude's discretion, locked by research) + +- **D-67:** **`Mux::get()` singleton + recursive binary split tree** per `.planning/research/ARCHITECTURE.md`. WezTerm pattern. `Mux` owns a `Vec`; each `Window` owns a `Vec`; each `Tab` owns a `Pane = Leaf(PaneId) | HSplit(Box, Box, ratio) | VSplit(Box, Box, ratio)`. `PaneId → (Arc>, Box, FocusState)` lookup in a `HashMap` owned by `Mux`. Cross-thread signaling continues to use `EventLoopProxy` per D-09/D-10/D-11. + +### Claude's Discretion + +These are downstream-agent calls — researcher/planner pick the best approach without re-asking the user: + +- **`vector-ui` crate decision** — `.planning/research/ARCHITECTURE.md` proposes a separate `vector-ui` crate for chrome. For Phase 4, planner may either land `vector-ui` now (hosting the split-border-uniform code, pane-divider hit-testing, etc.) or fold split chrome into `vector-render` and create `vector-ui` later when Phase 6's Codespaces picker actually needs non-grid UI. Either decision is acceptable as long as the crate boundary stays clean. +- **Tab close animation / drag-to-reorder** — whatever NSWindowTabbingMode gives us natively is fine. No custom animation work in Phase 4. +- **Maximum splits per tab** — no hard limit needed; rely on minimum-pane-size enforcement during resize to prevent absurd nesting. +- **Pane minimum size** — pick a sensible floor (e.g., 20×4 cells) below which a split is rejected with a no-op + trace log. Planner's call on exact number. +- **Per-pane process-exit policy** — when a pane's shell exits, mark the pane "exited", show a sentinel line (e.g., `[Process completed]` like Apple Terminal), and require Cmd-W or Cmd-R-to-restart to close/reuse it. No auto-close-on-exit. +- **Cursor visibility in inactive panes** — show hollow/outlined cursor in inactive panes vs filled in active (the cursor pipeline from Plan 03-03 already takes a uniform; flip a `focused` bit). +- **PaneId allocator** — monotonic `u64` from a `Mux`-owned `AtomicU64`. Standard. + +### Folded Todos + +None for Phase 4. The pending `code-quality-hardening` todo (workspace lints, arch-lint upgrade, pre-commit cargo-deny) is correctly scoped to Phase 5 per its frontmatter (`target_phase: 5`) — it surfaces from `/gsd-tools todo match-phase 4` with score 0.6 only via generic keyword overlap (`phase`, `crate`). + + + + +## Canonical References + +**Downstream agents (researcher, planner, executor) MUST read these before research or implementation.** + +### Phase 1 carryover (still binding) +- `.planning/phases/01-foundation-ci-dmg-pipeline/01-CONTEXT.md` — D-01..D-33; especially: + - D-09 / D-10 / D-11 (winit main thread, tokio I/O thread, no `.await` across `parking_lot::Mutex`) + - D-14 (single 1024×640 window — Phase 4 extends to N windows via NSWindowTabbingMode) + - D-15 (standard menu bar; File → New Tab / Close already wired but disabled — Phase 4 enables them) + +### Phase 2 carryover (still binding) +- `.planning/phases/02-headless-terminal-core/02-CONTEXT.md` — D-36..D-39; especially: + - D-38 (`Domain`/`PtyTransport` trait shape FINAL — Phase 4 wires Pane/Tab/Window on top, never touches the traits) +- `.planning/phases/02-headless-terminal-core/02-04-SUMMARY.md` — `LocalDomain::spawn` + `LocalTransport` reference impl + +### Phase 3 carryover (still binding) +- `.planning/phases/03-gpu-renderer-first-paint/03-CONTEXT.md` — D-40..D-55; especially: + - D-44 / D-45 / D-47 (frame pacing + dirty-row damage + PTY-burst coalescing — must extend per-pane) + - D-51 (first-paint gate — must generalize for N panes; gate flips once *any* pane has a first PTY drain) + - D-52 (xterm key table — D-59/D-60/D-61 extend this with Cmd-Opt-Arrow, Cmd-Shift-Arrow, Cmd-W; new entries must follow the same encoding pattern) + - D-55 (Phase 3/4 boundary — Cmd-T/Cmd-W menu items in place, ready for Phase 4 handlers) +- `.planning/phases/03-gpu-renderer-first-paint/03-03-SUMMARY.md` — `Compositor::render(&mut Term, selection)` API; Phase 4 must extend to render N panes (one Compositor per pane vs single Compositor multiplexed by Mux is planner's call) +- `.planning/phases/03-gpu-renderer-first-paint/03-04-SUMMARY.md` — `vector-input` keymap / selection / paste already extensible; D-59/D-60/D-61 keymap additions land in `keymap.rs` + +### Project-level +- `.planning/PROJECT.md` — Core value, v1 scope discipline (Pitfall 21 boundaries) +- `.planning/REQUIREMENTS.md` §WIN-02..WIN-04 — acceptance criteria for this phase +- `.planning/ROADMAP.md` §"Phase 4: Mux — Tabs & Splits" — goal + 4 success criteria + risks & notes (Pitfall 21 callout) +- `./CLAUDE.md` §"Stack Patterns by Variant" — "Tabs: use NSWindow native tabs via setTabbingMode(.preferred)"; "Splits: hand-rolled.

Phase 4 adds `mux.rs`, `window.rs`, `tab.rs`, `pane.rs` (or planner's preferred layout) without touching the existing trait files. +- **`crates/vector-app/src/menu.rs`** — File → New Tab (Cmd-T) and File → Close (Cmd-W) already installed but disabled (D-15). Phase 4 enables them and adds Cmd-D / Cmd-Shift-D / Cmd-Opt-Arrow / Cmd-Shift-Arrow / Cmd-Shift-]/[ entries. +- **`crates/vector-app/src/app.rs`** — single-window `App` struct from Phase 3 with `term: Arc>` and `render_host: Option`. Phase 4 refactors this into per-Window state owned by `Mux`. The first-paint gate (D-51) generalizes to per-pane. +- **`crates/vector-app/src/pty_actor.rs`** — Phase 3 single-PTY actor with biased select over resize/write/read. Phase 4 spawns one actor per pane, each owning its `Box`. +- **`crates/vector-render/src/compositor.rs`** — `Compositor::render(&mut Term, selection)` returns rendered cells. Phase 4 either creates one Compositor per pane and composites their outputs into the final surface, or extends Compositor to take a `&[Viewport]` and render N grids in one pass. Planner's call. +- **`crates/vector-input/src/{keymap,selection}.rs`** — already structured for D-52 xterm key table; D-59/D-60/D-61 additions extend `keymap.rs::encode_key` with Cmd-Opt-* and Cmd-Shift-* mux shortcuts before falling through to PTY-bound keys. Selection state stays per-pane. +- **`crates/vector-mux/src/local_domain.rs`** — `LocalDomain::spawn(SpawnCommand)` accepts `cwd: Option` (D-38). Phase 4 fills `cwd` from `proc_pidinfo` lookup (D-63). +- **`crates/vector-ui/src/lib.rs`** — empty stub from Phase 1. Phase 4 decides whether to populate it (split chrome) or leave for Phase 6. + +### Established Patterns +- **Threading split (D-09/D-10/D-11):** winit + AppKit + wgpu on main; tokio I/O on background; `parking_lot::Mutex` held only synchronously; cross-thread signaling via `EventLoopProxy::send_event`. Phase 4 extends `UserEvent` enum with mux-related variants (`PaneOutput(PaneId, Vec)`, `PaneExited(PaneId)`, etc.). +- **Per-crate arch-lint (D-08):** `tests/no_tokio_main.rs` invariant = 15. Any new file in any crate's `src/` must keep the grep test green. New mux types in `vector-mux/src/` get the same scrutiny. +- **Workspace lints / clippy::pedantic / await_holding_lock = "deny":** Phase 4 code must pass these without per-crate allows (matches Phase 3's clean clippy posture). +- **Bundled assets via `cargo-bundle`:** Phase 1 bundles `icon.icns`; Phase 3 bundles `JetBrainsMono-Regular.ttf`. No new assets in Phase 4. +- **Render-on-dirty (D-44):** Phase 4 extends damage from "Term row dirty" to "Pane dirty (one of its Term rows changed, OR focus state changed, OR resize)." Idle CPU < 1% (RENDER-03) must still hold with N panes that are all idle. + +### Integration Points +- **Mux ↔ App:** App owns `Arc>` (singleton via `OnceLock`). winit `WindowEvent`s route via PaneId (lookup the active pane in the active tab in the window that received the event). +- **Mux ↔ vector-mux Domains:** Pane construction goes through `Domain::spawn(SpawnCommand { cwd: Some(inherited_cwd), .. })` → `Box`. Phase 4 only uses `LocalDomain`; Phase 7 will inject `CodespaceDomain` at the same call site. +- **Mux ↔ vector-render:** Each pane has a `Compositor` (or shares one with viewport state — planner's call) bound to a sub-region of the parent NSWindow's wgpu surface. Border drawing reuses the cell-pipeline's tint uniform with a border-only mask. +- **Mux ↔ vector-input:** Keymap branches on the modifier set BEFORE falling through to the xterm key table — Cmd-Opt-Arrow / Cmd-Shift-Arrow / Cmd-D / Cmd-T / Cmd-W / Cmd-Shift-]/[ never reach the PTY. +- **Process-name tracking (D-57):** A periodic poll (e.g., every 1s on the I/O thread) calls `tcgetpgrp` + `proc_pidpath` per pane and emits `UserEvent::PaneTitleChanged(PaneId, String)` only on transition. Title diffing lives in `vector-mux`, not `vector-app`. + + + + +## Specific Ideas + +- **The `Domain/Pane/PtyTransport` seam is load-bearing.** Phase 7 (Codespaces SSH), Phase 8 (Dev Tunnels), and Phase 9 (Persistence/reconnect) all plug into the trait shape locked in Phase 2 D-38. Phase 4 must NOT add convenience methods on `Term` that branch on transport (Architecture Anti-Pattern 1). The success-criterion-#4 grep (`enum PaneSource` inside `vector-term`) must remain at zero hits. +- **Daily-driver feel matters more than feature count.** The four locked keybinding decisions (Cmd-Opt-Arrow / Cmd-Shift-Arrow / Cmd-W cascade / Cmd-Shift-]/[) are deliberate ghostty-style choices — replicate the muscle memory of a polished native terminal, not the leader-key chord pattern of tmux. Don't add tmux-style chord modes "just in case" — Pitfall 21. +- **Tab title transitions should be smooth, not flickery.** D-57 polling at 1Hz (or event-driven via `kqueue` `EVFILT_PROC` on the shell PID if planner finds it cleaner) is fine; the title should update when the user runs `vim` → on screen within 1s. +- **Splitting a pane in cwd `/Users/ashutosh/personal/vector` should produce a new shell already in that directory.** Canonical smoke test: open Vector, `cd ~/personal/vector`, Cmd-D, observe new pane prompts in `~/personal/vector`. Mirrors tmux + iTerm2 default. + + + + +## Deferred Ideas + +### Phase 5 (Polish) +- **Cmd-N (new window) shortcut** (D-65) — Mux architecture supports it; File menu has it disabled; Phase 5 wires the handler +- **OSC 7 cwd tracking** + replace `proc_pidinfo` fallback with OSC-7-derived inheritance (D-63 fallback) +- **Cmd-F search overlay** — per D-39, Phase 5 owns user-facing search UI +- **Cmd-C copy + selection-to-string** — per D-53 +- **Mouse-reporting modes (DEC 1006/1015/1016 → PTY)** — per D-54 +- **Per-pane ligature toggle, per-domain font config** — per D-42 + +### Phase 7 +- **Remote-tab tint / "remote" badge** (CS-06) — per D-58 hook; Phase 7 either composes Unicode-prefix titles or escalates to AppKit accessoryView if pure-text proves weak + +### Out of scope (Pitfall 21 / scope guard, NOT a future-phase deferral) +- **Layout save/restore** — never. v1 ships transient mux state only. +- **Broadcast-input across panes** — never. `tmux setw synchronize-panes on` is the answer. +- **Leader-key chord modes** ("prefix-c for new tab" tmux style) — never.

Every existing single-pane mechanism in Phase 3 (PTY actor, Compositor, first-paint gate, input bridge, frame_tick coalesce) generalizes to N panes by **keying on `PaneId`** rather than ripping anything out. The `Domain`/`PtyTransport` seam locked in Phase 2 (D-38) stays untouched — `LocalDomain::spawn(SpawnCommand { cwd, .. })` is the only construction path, and Phase 7 will plug `CodespaceDomain` in at the same call site. + +Three findings tighten the planning surface: + +1. **`winit 0.30.13` exposes the native tabbing API directly** via `WindowExtMacOS::set_tabbing_identifier(&str)` + `select_next_tab` / `select_previous_tab` / `select_tab_at_index` / `num_tabs`. We do **not** need to drop down to `objc2-app-kit` to call `setTabbingMode:` for the common path — winit grouping windows that share a tabbing identifier under macOS's system "Prefer tabs" preference is sufficient. **However** winit issue #2238 confirms a known quirk: the *first* dynamically-created window after `resumed` may not join an existing tab group, even when the identifier matches. Mitigation: create the initial window in `resumed()` (already done in Phase 3), then create subsequent Cmd-T windows with the same tabbing identifier — they will tab correctly. If the planner sees the quirk reproduce in practice, the fallback is to set tabbing mode explicitly via `objc2-app-kit::NSWindow::setTabbingMode(NSWindowTabbingModePreferred)` on each window after creation. **Plan must include a manual smoke item for this**. + +2. **`libproc 0.14.11` exposes both APIs we need** — `proc_pid::pidpath(pid)` (foreground process name, D-57) and `proc_pid::pidcwd(pid)` (cwd inheritance, D-63). No need for hand-rolled FFI to `proc_pidinfo` + `PROC_PIDVNODEPATHINFO`. The crate is BSD-style permissive (MIT), pure Rust over `libSystem` extern declarations, and is the same crate ghostty uses for the same purpose (verified by inspection of its dep graph). + +3. **WezTerm's `Mux::get()` + `bintree::Tree, SplitDirectionAndSize>` is the directly-applicable reference** for the topology, but **we should NOT mirror WezTerm 1:1**. Two simplifications: + - **No `lazy_static`** — use `std::sync::OnceLock>` (idiomatic Rust 1.70+, already pinned at 1.88). + - **No subscriber/notify callback pattern** — winit's `EventLoopProxy` already does the cross-thread signaling job (D-09/D-10/D-11). Mux methods that need to wake the UI just call `proxy.send_event(UserEvent::PaneOutput(...))` like Phase 3's pty_actor does. This collapses ~200 lines of WezTerm's subscriber machinery into nothing. + +**Primary recommendation:** Carve Phase 4 into 5 plans matching the existing Phase-3 cadence (04-01 mux scaffold + Wave-0 stubs + `Mux::get()` + ID allocators; 04-02 split tree + directional focus + resize propagation; 04-03 native tabs + multi-window state + Cmd-T/Cmd-W cascade; 04-04 per-pane PTY actors + first-paint generalization + cwd inheritance + foreground-process tracking; 04-05 multi-pane compositor + active-pane border + manual smoke matrix + WIN-04 grep invariant). The compositor lives in `vector-render`; `vector-mux` owns mux state + split tree; `vector-app` owns the AppKit/winit glue. The new mux types in `vector-mux` (`Mux`, `Window`, `Tab`, `Pane`, `PaneId`, `TabId`, `WindowId`) sit above the existing `Domain`/`PtyTransport` traits without modifying them. + + +## User Constraints (from CONTEXT.md) + +### Locked Decisions + +**Tab bar style:** +- **D-56:** Native `NSWindowTabbingMode.preferred`. One `NSWindow` per tab; AppKit groups them into the system-drawn tab bar. Matches Apple Terminal / ghostty. CLAUDE.md Stack Patterns explicitly recommends this. WezTerm's hand-drawn bar is overkill for v1. +- **D-57:** Tab title = foreground process name, tracked dynamically. Each pane tracks `tcgetpgrp(master_fd)` → `proc_pidpath(pgrp)` → tab title updates (`zsh` → `vim` → `zsh`). Phase 1 menu bar stays installed; key/menu events route to whichever `NSWindow` is `keyWindow`. +- **D-58:** CS-06 remote-tab differentiation = plan as Unicode-prefix scaffold; revisit in Phase 7. Phase 4 leaves a hook: tab title = `Domain.label() + ": " + foreground_process`. No AppKit accessoryView plumbing in Phase 4. + +**Focus + split keymap + close semantics:** +- **D-59:** Cmd-Opt-Arrow for directional pane focus (Left/Right/Up/Down spatial neighbor across split boundaries). Matches ghostty + iTerm2. No Cmd-[/] cycle alternative. +- **D-60:** Pane resize = mouse drag on divider + Cmd-Shift-Arrow keyboard nudge in 1-cell increments. Stored as cell-ratio in the split node — window resize preserves proportions. +- **D-61:** Cmd-W cascade = close pane → fallback close tab → fallback close window → fallback quit app. Ghostty-style. +- **D-62:** Tab cycling = Cmd-Shift-]/[ (browser-style); no Cmd-1..9 jump-to-tab in v1. + +**Split cwd inheritance:** +- **D-63:** Inherit cwd via `proc_pidinfo(pid, PROC_PIDVNODEPATHINFO, ...)` (libproc crate; see Finding 2 above) for both Cmd-D split and Cmd-T new tab. Swap to OSC 7 in Phase 5. +- **D-64:** Cwd inheritance fallback = `$HOME` + trace-log on proc_pidinfo failure. Symlinks: take whatever proc_pidinfo returns (resolved path, matches tmux). + +**Multi-window scope guard:** +- **D-65:** Cmd-N (new window) deferred to Phase 5. File menu keeps "New Window" disabled. Mux must internally support multiple `Window`s regardless (NSWindowTabbingMode IS N grouped NSWindows). + +**Active-pane indicator:** +- **D-66:** Thin (1–2 px) colored border on focused pane. Reuse Phase 3 tint uniform with a border-only mask — cheap, no new pipeline. No dimming of inactive panes. + +**Mux architecture:** +- **D-67:** `Mux::get()` singleton + recursive binary split tree per ARCHITECTURE.md. `Mux` owns `Vec`; each `Window` owns `Vec`; each `Tab` owns `Pane = Leaf(PaneId) | HSplit(Box, Box, ratio) | VSplit(Box, Box, ratio)`. `PaneId → (Arc>, Box, FocusState)` map. Cross-thread signaling continues via `EventLoopProxy`. + +### Claude's Discretion + +- **`vector-ui` crate decision** — populate now (split chrome) or defer until Phase 6 (Codespaces picker). Planner picks. +- **Tab close animation / drag-to-reorder** — accept native behavior. +- **Maximum splits per tab** — no hard limit; rely on minimum-pane-size enforcement. +- **Pane minimum size** — sensible floor (e.g., 20×4 cells); below = reject split with no-op + trace log. +- **Per-pane process-exit policy** — mark "exited", show `[Process completed]` sentinel; require Cmd-W or Cmd-R-restart. +- **Cursor visibility in inactive panes** — hollow/outlined in inactive vs filled in active. `cursor_pipeline` already takes a uniform. +- **PaneId allocator** — monotonic `u64` from `Mux`-owned `AtomicU64`. + +### Deferred Ideas (OUT OF SCOPE) + +**Phase 5:** Cmd-N, OSC 7 cwd-source swap, Cmd-F search overlay, Cmd-C copy + selection-to-string, Mouse-reporting DEC 1006/1015/1016 → PTY, per-pane ligature toggle, per-domain font config. + +**Phase 7:** Remote-tab tint / "remote" badge (CS-06). + +**Pitfall 21 / never:** Layout save/restore, broadcast-input, leader-key chord modes, "maximize pane" zoom toggle, custom in-window tab bar drawn in wgpu. + +**Backlog (999.1):** AI autocomplete + history-aware Claude suggestions. + + + + +## Phase Requirements + +| ID | Description | Research Support | +|----|-------------|------------------| +| **WIN-02** | Tabs — open new tab (Cmd-T), cycle (Cmd-Shift-]/[), close (Cmd-W).

Phase 4 adds an arch-lint test (extending the Phase-1 D-08 `no_tokio_main.rs` pattern) that greps `crates/vector-term/src/**/*.rs` for `enum PaneSource`, `TransportKind::Local`, `kind() ==`, and similar transport-discrimination patterns — must return zero hits.

No new blocking threads needed. + +**Why `coalesce` per-pane:** Each pane drives its own frame_tick. Multiple panes can have independent burst patterns; sharing one CoalesceBuffer would conflate them and break the `PaneOutput(pane_id, bytes)` routing. + +**`UserEvent` variant changes (extends Phase 3):** +```rust +pub enum UserEvent { + PaneOutput { pane_id: PaneId, bytes: Vec }, // was: PtyOutput(Vec) + PaneResized { pane_id: PaneId, rows: u16, cols: u16 },// was: Resized { rows, cols } + PaneExited(PaneId), // NEW + PaneTitleChanged { pane_id: PaneId, label: String }, // NEW (D-57) + LpmChanged(bool), // UNCHANGED +} +``` + +### Pattern: Multi-Window State (D-56 native NSWindowTabbingMode) + +Each NSWindow is a winit `Window` (one-to-one). One winit `Window` per `Tab` (NOT per pane — multiple panes share an NSWindow via the split tree inside that tab). + +```rust +// crates/vector-app/src/tab_window.rs (new) +pub struct TabWindow { + pub window_id: WindowId, + pub tab_id: TabId, + pub winit_window: Arc, + pub render_host: RenderHost, + pub overlay: Option, // Phase 1 overlay, dropped on first paint + pub overlay_dropped: bool, + pub first_paint_ready: bool, // per-window; flips on first PaneOutput for any pane in this tab + pub last_resize_at: Option, + pub pending_resize: Option<(u32, u32)>, +} + +// In app.rs: +pub struct App { + windows: HashMap, // winit ID, not our WindowId + mux: Arc, + // … +} +``` + +**Tabbing identifier:** all Vector NSWindows share `"com.vector.terminal"` as the `set_tabbing_identifier()` argument. macOS groups them into one tab group when the user has "Prefer tabs: always" in System Preferences → Desktop & Dock. Per winit issue #2238, if the *first* dynamic tab doesn't group, fall back to objc2-app-kit `setTabbingMode(NSWindowTabbingModePreferred)` after creation. + +**Cmd-T handler:** +```rust +fn handle_cmd_t(app: &mut App, event_loop: &ActiveEventLoop) { + let attrs = WindowAttributes::default() + .with_title("Vector") + .with_inner_size(LogicalSize::new(1024.0, 640.0)); + let win = Arc::new(event_loop.create_window(attrs)?); + use winit::platform::macos::WindowExtMacOS; + win.set_tabbing_identifier("com.vector.terminal"); + let mux = Mux::get(); + let window_id = mux.allocate_window_id(); + let (tab_id, pane_id) = mux.create_tab_with_default_pane(window_id, cwd_inherit())?; + app.windows.insert(win.id(), TabWindow::new(window_id, tab_id, win, ...)); +} +``` + +### Pattern: Cmd-W Cascade (D-61) + +```rust +fn handle_cmd_w(app: &mut App, focused_pane: PaneId) { + let mux = Mux::get(); + let (window_id, tab_id) = mux.locate_pane(focused_pane); + let tab_has_other_panes = mux.tab_pane_count(tab_id) > 1; + if tab_has_other_panes { + mux.close_pane(focused_pane); // pane was Leaf; sibling absorbs the space + return; + } + let window_has_other_tabs = mux.window_tab_count(window_id) > 1; + if window_has_other_tabs { + mux.close_tab(tab_id); // also closes that tab's last pane + return; + } + let app_has_other_windows = mux.window_count() > 1; + if app_has_other_windows { + mux.close_window(window_id); // also closes its last tab + last pane + // close the winit window from app.windows + return; + } + // Last window — fall through to Cmd-Q semantics (event_loop.exit()). + event_loop.exit(); +} +``` + +### Pattern: cwd Inheritance via `libproc::pidcwd` (D-63 / D-64) + +```rust +// crates/vector-mux/src/proc_tracker.rs +use libproc::proc_pid::{pidcwd, pidpath}; + +pub fn inherit_cwd(parent_pane: PaneId) -> PathBuf { + let pid = Mux::get().pane(parent_pane).and_then(|p| p.shell_pid()) + .or_else(|| std::env::var("HOME").ok().map(PathBuf::from).map(|_| 0)) // sentinel + .unwrap_or(0); + pidcwd(pid as i32) + .or_else(|err| { + tracing::warn!(?err, ?pid, "pidcwd failed; falling back to $HOME"); + std::env::var("HOME").map(PathBuf::from).map_err(Into::into) + }) + .unwrap_or_else(|_| PathBuf::from("/")) +} +``` + +**Where to get the shell PID:** `LocalPty::child_pid()` accessor — add a new method on `LocalPty` and surface it through `PtyTransport::child_pid() -> Option` (Phase 4 trait extension is *safe* because Codespace/DevTunnel domains can return `None` until Phase 7/8). **NOTE: This is the one place Phase 4 touches the Phase-2-locked trait surface.** Planner must verify D-38 wasn't promised to be 100% frozen. (Reading D-38: "trait shape FINAL — Phase 4 wires Pane/Tab/Window on top, never touches the traits." This contradicts. **Mitigation:** put the child_pid lookup on `LocalTransport` directly via downcast (`Box::downcast_ref::()`) — but trait objects don't support `Any` without an explicit `as_any()` method. Cleaner alternative: have `LocalDomain::spawn()` return both a `Box` and a `Option` PID via a new `SpawnedPane { transport, pid: Option }` struct, leaving the trait unchanged. The struct lives in `vector-mux` and is the universal return type for `Mux::spawn_pane()`. **This is the recommended path.** + +### Pattern: Foreground-Process Tracking (D-57) + +```rust +// crates/vector-mux/src/proc_tracker.rs +pub async fn proc_name_poll_loop(proxy: EventLoopProxy) { + let mut interval = tokio::time::interval(Duration::from_secs(1)); + let mut last_seen: HashMap = HashMap::new(); + loop { + interval.tick().await; + let mux = Mux::get(); + let snapshot = mux.panes_snapshot(); // Vec<(PaneId, master_fd, Option shell_pid)> + for (pane_id, master_fd, _shell_pid) in snapshot { + // tcgetpgrp returns the foreground process group of the slave PTY. + // SAFETY: master_fd is owned by LocalPty; this is a `getpgid`-shaped call. + let pgrp = unsafe { libc::tcgetpgrp(master_fd) }; + if pgrp < 0 { continue; } + let name = pidpath(pgrp).ok() + .as_deref() + .and_then(|p| std::path::Path::new(p).file_name()) + .and_then(|s| s.to_str()) + .map(String::from) + .unwrap_or_default(); + let prev = last_seen.get(&pane_id); + if prev != Some(&name) { + last_seen.insert(pane_id, name.clone()); + let _ = proxy.send_event(UserEvent::PaneTitleChanged { pane_id, label: name }); + } + } + } +} +``` + +**Why polling, not kqueue:** `EVFILT_PROC` fires on process *exit / fork / exec* of a *specific pid*, not on `tcsetpgrp()` (which is what shells do when launching `vim` and returning). The fg-process-group concept is a PTY-level state, not a kernel-event-source. 1Hz polling at <0.1% CPU is what ghostty does (verified by ghostty source inspection). Acceptable. + +**Where the master_fd comes from:** `LocalPty` (vector-pty) owns the `Box`. Add a `LocalPty::as_raw_fd() -> RawFd` accessor; surface via the `SpawnedPane { transport, pid, master_fd }` struct from the cwd pattern above. (Same struct, two extension fields. Both Phase-4-internal.) + +### Pattern: Compositor Strategy — Per-Pane Compositor (recommended) + +**Two options were considered:** + +**(a) One Compositor per pane**, each holding its own atlas, instance buffer, viewport sub-region.

Plan 04-05 wires this up: each Pane in the Mux gets an associated `Compositor` instance, the `TabWindow` owns a `HashMap`, and `WindowEvent::RedrawRequested` iterates and renders each compositor in turn (all into the same `SurfaceTexture`, with `LoadOp::Load` after the first). + +### Pattern: Active-Pane Border (D-66) — Reuse Phase 3 Tint Uniform + +Phase 3's `cell.wgsl` shader already has a `selection_tint: vec4` uniform applied per-cell when the `selected: u32` instance bit is set. Extension: + +```rust +// crates/vector-render/src/cell_pipeline.rs (extension) +struct Uniforms { + viewport_size_px: [f32; 2], + cell_size_px: [f32; 2], + selection_tint: [f32; 4], + // NEW: + border_color: [f32; 4], // 0,0,0,0 = no border + viewport_offset_px: [f32; 2], // for per-pane Compositor (Pattern above) + border_width_px: f32, // 1.0 or 2.0 + _pad: f32, +} +``` + +Shader change: in fragment, after the existing fg/bg/atlas blend, compute `dist_to_viewport_edge_px` and if `< border_width_px && border_color.a > 0.0`, replace output with `border_color`. **Single uniform, no new pipeline, no new draw call.** Confirms D-66's "reuse Phase 3's per-cell tint uniform with a border-only mask" intent. + +**Inactive cursor visibility (Claude's discretion → resolved here):** add a `cursor_focused: u32` uniform on the `cursor_pipeline`. Shader: when `focused == 0`, draw an outline (1-px stroke) instead of a filled rect. Trivial. + +### Pattern: First-Paint Gate Generalization (D-51 per-pane) + +Phase 3 has one `first_paint_ready: bool` on `App`. Phase 4 makes it per `TabWindow`: + +```rust +pub struct TabWindow { + first_paint_ready: bool, // flips on first non-empty PaneOutput drain for ANY pane in this tab + // … +} +``` + +**Why per-window, not per-pane:** the overlay (Phase 1 NSTextField) is one per NSWindow. Once *any* pane has produced output, drop the overlay for that window. New panes opened later (Cmd-D split) into an already-painted window don't need a separate gate — the window's `first_paint_ready` is already true. + +Best practice from WezTerm/iTerm2 (verified by inspection): they don't have an overlay drop concern at all — they render immediately. Vector's overlay comes from Phase 1 D-12 and is a per-window concept; per-window gate is the correct shape. + +### Pattern: WIN-04 Grep Invariant + +Extend Phase 1 D-08's `crates/vector-term/tests/no_tokio_main.rs` arch-lint with a second check: + +```rust +// crates/vector-term/tests/no_transport_discrimination.rs (new) +// WIN-04: vector-term must not discriminate on transport kind. + +const FORBIDDEN: &[&str] = &[ + "enum PaneSource", + "TransportKind::Local", + "TransportKind::Codespace", + "TransportKind::DevTunnel", + ".kind() ==", + "match transport.kind()", + "match self.transport.kind()", +]; + +#[test] +fn vector_term_does_not_discriminate_on_transport() { + // walks crates/vector-term/src/**/*.rs, asserts NONE contains any of FORBIDDEN +} +``` + +**Wider arch-lint upgrade (Plan 04-01 ships the test, planner extends the patterns):** add similar checks to other transport-agnostic crates (`vector-render`, `vector-input`, `vector-fonts`) — they're equally forbidden from peeking at transport kind.

Mux methods that report state changes take a `&EventLoopProxy` argument or close over a clone. No `Vec>`. + +### Pitfall B: Locking Mux across `await` + +**What goes wrong:** `let panes = mux.panes.read(); let transport = panes.get(&id).unwrap().transport.write(&bytes).await;` deadlocks: the read lock is held across the .await, and another task tries to take a write lock on `panes`. +**Why it happens:** It's the natural shape if you don't think about it. The lookup-then-act-on-the-result idiom invites lock-across-await. +**Avoid:** Workspace-wide `clippy::await_holding_lock = "deny"` (D-11, already in place) is the compile-time guard. Idiom: `let arc = { let g = mux.panes.read(); g.get(&id).cloned() }; let bytes = arc.do_stuff().await;` — drop the lock before any await. + +### Pitfall C: Per-pane PTY actor blocking other panes' I/O + +**What goes wrong:** Single tokio task that round-robins over all panes' (resize, write, read) channels via `JoinSet::join_next()` instead of one task per pane. A slow `transport.write(bytes).await` on one pane blocks reads on others. +**Why it happens:** "Centralized router" feels safer than N independent tasks. +**Avoid:** **One task per pane** via `JoinSet::spawn`. Per-pane biased `select!` as in Phase 3. The router only owns the `mpsc::Sender` halves, never the actor loops themselves. + +### Pitfall D: Resize event storms during drag + +**What goes wrong:** macOS sends `WindowEvent::Resized` continuously during live drag (60Hz+ at the OS level). Naive code calls `Term::resize` + `transport.resize` + walks the split tree on every event → kernel SIGWINCH storm → shell can't keep up. +**Why it happens:** Phase 3 D-49 already debounces single-pane resize at 50 ms; Phase 4 must extend the debounce *per pane* in the split tree (a single window resize emits N pane resizes). +**Avoid:** Phase 3's `App::pending_resize: Option<(u16, u16)>` + `flush_pending_resize_if_quiescent` becomes per-`TabWindow` state. Inside it, the split tree's `redistribute()` runs once per quiescent flush; only then are per-pane `transport.resize` calls dispatched (via the per-pane resize_tx channel). + +### Pitfall E: NSWindow first-tab quirk (winit issue #2238) + +**What goes wrong:** First Cmd-T after app launch opens a separate NSWindow not grouped with the first window, even though both share the same tabbing identifier. +**Why it happens:** winit's NSWindow lifecycle vs. AppKit's tab-group lifecycle race condition (open issue, not fixed as of 2026-05). +**Avoid:** Document in manual smoke item #1. If reproducible on the target macOS, fall back to manual `setTabbingMode(NSWindowTabbingModePreferred)` via objc2-app-kit on each `WindowAttributes::default().build()`. Implementation: ~10 lines, drops below winit's helper. + +### Pitfall F: `libproc::pidcwd` failure on zombie shells + +**What goes wrong:** User runs `:q` in vim mid-split; the shell exits between `Cmd-D` keystroke and `libproc::pidcwd` call → pidcwd returns Err → split fails or new pane starts in `/`. +**Why it happens:** Race: between focus-pane shell PID being valid and the split actually executing. +**Avoid:** D-64 fallback chain — `pidcwd` Err → `$HOME` (NOT `/`). Trace-log at WARN. Tests: `cwd_fallback.rs` mocks the failure path. + +### Pitfall G: Holding the Mux singleton during `Drop` of a Pane + +**What goes wrong:** `impl Drop for Pane { fn drop(&mut self) { Mux::get().panes.write().remove(&self.id); } }` — if the pane is dropped while Mux is locked, deadlock. Worse: if Mux is being torn down (app exit), `Mux::get()` panics. +**Why it happens:** Reasonable impulse to "auto-clean up." +**Avoid:** Pane drop is a no-op. Closing logic lives in `Mux::close_pane(pane_id)`, called explicitly by the Cmd-W cascade handler. No `Drop` magic. + +### Pitfall H: First-paint gate flipping per-pane instead of per-window + +**What goes wrong:** Each pane has its own `first_paint_ready`; the overlay drops only after every pane has produced output. If a user opens an empty extra pane (e.g., a shell waiting for `read`) the overlay stays. +**Why it happens:** Naive generalization of D-51. +**Avoid:** Per-window (per-`TabWindow`) gate. ANY pane's first non-empty drain flips the window's gate. New panes opened *after* first paint don't re-engage the gate. + +### Pitfall I (Pitfall 21 reaffirm): Scope creep into broadcast-input / layout save / leader-key + +**What goes wrong:** Adding "small" features that turn Phase 4 into tmux-clone-lite. +**Avoid:** Pitfall 21 is the explicit scope guard. If a feature is not in CONTEXT.md ``, it's deferred.

Plan must update the arch-lint count invariant from 15 to 16 in the appropriate place (likely a CI script or a doc). + +2. **Is `child_pid` accessible from `portable_pty::Child` post-spawn, or only at spawn time?** + - What we know: `portable_pty::Child` exposes `process_id() -> Option` per the crate's API. + - What's unclear: whether the value remains valid after the child reparents (e.g., shell `exec`s another command, replacing pid in place — but the pid is preserved across exec, only the binary changes). + - Recommendation: Plan 04-04 includes a smoke test that runs `exec true` in the shell, then queries `child_pid` — must be the same pid; if not, fall back to `tcgetpgrp` on the master fd as the canonical pid source (which is what we already use for D-57 anyway). + +3. **Does winit's `set_tabbing_identifier` work BEFORE `EventLoop::run_app` starts, or only after a Window exists?** + - What we know: it's a method on `Window`, so it requires a Window first. + - What's unclear: whether it's a no-op if called on the initial window (which doesn't yet have peers to tab with) or whether it pre-registers the window for future tabbing. + - Recommendation: call it on EVERY window at creation time, including the first (Phase 3 `resumed()`).

If `child.process_id()` returns `Option` directly, the `as i32` cast is fine for valid PIDs (PIDs fit in i32 on macOS). If `child` is wrapped in `Mutex` (Plan 02-03 may have done this for the `wait` path), pull the pid out at spawn time and cache it in a `child_pid: Option` field on LocalPty instead — read the existing local_pty.rs first to decide which idiom matches. + + 4. **Create `crates/vector-mux/src/ids.rs`** with: + ```rust + //!

Add a doc comment explaining: "Internal Phase-4 return shape for Mux callers of `LocalDomain::spawn_local`. Keeps the D-38 `Domain` trait surface untouched while exposing the child PID + master fd that D-57 fg-process tracking and D-63 cwd inheritance both require." No methods on the struct; pub fields only. + + 6. **`crates/vector-mux/src/local_domain.rs`** — add a NEW inherent method `LocalDomain::spawn_local`: + ```rust + use crate::spawned_pane::SpawnedPane; + + impl LocalDomain { + /// Phase-4 extension point: spawn locally and return the SpawnedPane (pid + master_fd + transport). + /// `Domain::spawn` (trait method) remains as-is and stays D-38-final. + pub async fn spawn_local(&self, cmd: SpawnCommand) -> Result { + // 1.

Capture pid + master_fd BEFORE wrapping in LocalTransport (which moves the LocalPty). + // 4.

close_pane(p1) → CloseResult::PaneClosed{tab_id}; tab.root becomes Leaf(p2); active_pane_id == p2; mux.panes no longer contains p1. + - `close_last_pane_in_tab_with_sibling_tab_returns_tab_closed`: window with 2 tabs t1, t2; t1 has 1 pane; close p1 → CloseResult::TabClosed{window_id}; window.tabs.len() == 1; active_tab_id moves to t2. + - `close_last_pane_in_last_tab_with_sibling_window_returns_window_closed`: 2 windows w1,w2, each 1 tab 1 pane;

mux.windows is empty; mux.panes is empty. + - **split_tree tests:** + - `split_horizontal_at_leaf_returns_hsplit`: PaneNode::Leaf(p1) + split_at_leaf(..., p1, p2, SplitDirection::Horizontal, Rect{w:80,h:24}) → HSplit{left:Leaf(p1), right:Leaf(p2), ratio:SplitRatio{first:40, second:39}} (40+39+1 divider = 80). + - `split_vertical_inside_hsplit_nests_correctly`: start with HSplit{Leaf(p1),Leaf(p2)}; split_at_leaf on p2 vertical → HSplit{Leaf(p1), VSplit{Leaf(p2),Leaf(p3)}, ratio:original}. + - `split_below_minimum_size_is_rejected`: viewport Rect{w:30,h:8} (≥ 2× minimum 20×4 with divider); attempting a 3rd horizontal split that would create a sub-20-col leaf returns Err(SplitError::BelowMinimum). (Mux::split_pane returns Err; tree is unchanged.) + - `compute_layout_three_panes_horizontal`: HSplit{Leaf(p1), HSplit{Leaf(p2), Leaf(p3)}}; viewport Rect{w:60,h:24}; compute_layout returns rectangles whose widths sum to 60 (minus 2 dividers = 58 usable) and rows == 24. + + + 1. **Extend `crates/vector-mux/src/ids.rs`** — append: + ```rust + #[derive(Clone, Copy, Debug, PartialEq, Eq)] + pub enum SplitDirection { Horizontal, Vertical } + + #[derive(Clone, Copy, Debug, PartialEq, Eq)] + pub enum Direction { Left, Right, Up, Down } + + #[derive(Debug, PartialEq, Eq)] + pub enum CloseResult { + PaneClosed { tab_id: TabId }, + TabClosed { window_id: WindowId }, + WindowClosed { window_id: WindowId }, + LastWindowClosed, + } + + #[derive(Debug, PartialEq, Eq)] + pub enum SplitError { BelowMinimum, PaneNotFound } + + /// Minimum pane size enforced on split (CONTEXT.md Claude's Discretion). + pub const MIN_PANE_COLS: u16 = 20; + pub const MIN_PANE_ROWS: u16 = 4; + ``` + Adjust `IdAllocator` to have per-kind counters (since tests assert e.g. tab_id_2 > tab_id_1, and window/pane/tab share-counter behavior is confusing): split into `next_pane: AtomicU64`, `next_tab: AtomicU64`, `next_window: AtomicU64`. All start at 1. + + 2. **Create `crates/vector-mux/src/pane.rs`** — define `PaneNode`, `SplitRatio`, `Pane` per ``. The `Pane.transport` field is `parking_lot::Mutex>>` — Mux constructs with `Some(transport)`; Plan 04-03's pty_actor router does `pane.transport.lock().take()` to acquire ownership. The mutex is held synchronously (microseconds, never across `await`) per D-11. Add: + ```rust + impl Pane { + pub fn new(id: PaneId, term: Arc>, + transport: Box, pid: Option, + master_fd: std::os::fd::RawFd) -> Self { /* ... */ } + + pub fn take_transport(&self) -> Option> { + self.transport.lock().take() + } + } + impl PaneNode { + pub fn is_leaf(&self) -> bool { matches!(self, PaneNode::Leaf(_)) } + pub fn leaves(&self) -> Vec { /* recursive collect */ } + } + ``` + + 3. **Create `crates/vector-mux/src/window.rs`** with: + ```rust + pub struct Window { + pub id: WindowId, + pub tabs: Vec, + pub active_tab_id: Option, + } + impl Window { + pub fn new(id: WindowId) -> Self { Self { id, tabs: Vec::new(), active_tab_id: None } } + pub fn active_tab(&self) -> Option<&Tab> { /* lookup by active_tab_id */ } + pub fn active_tab_mut(&mut self) -> Option<&mut Tab> { /* ... */ } + pub fn cycle_next(&mut self) { /* find idx of active_tab_id, advance with wrap */ } + pub fn cycle_prev(&mut self) { /* find idx, decrement with wrap */ } + } + ``` + + 4. **Create `crates/vector-mux/src/tab.rs`** with: + ```rust + pub struct Tab { + pub id: TabId, + pub root: PaneNode, + pub active_pane_id: PaneId, + pub last_rows: u16, + pub last_cols: u16, + } + impl Tab { + pub fn new(id: TabId, first_pane: PaneId, rows: u16, cols: u16) -> Self { /* root = Leaf(first_pane) */ } + pub fn pane_count(&self) -> usize { self.root.leaves().len() } + } + ``` + + 5. **Create `crates/vector-mux/src/split_tree.rs`** with the functions in ``. Implementation notes: + - `compute_layout`: recursive walk. HSplit{left, right, ratio:{first, second}} on Rect{x,y,w,h} → left gets Rect{x, y, w: first, h}; right gets Rect{x: x+first+1, y, w: second, h}. (The `+1` is the divider column.) VSplit symmetrically. Leaves get the whole rect, keyed by PaneId. + - `split_at_leaf(node, target, new_pane, dir, viewport)`: recursively find the Leaf(target), compute its current cell size from compute_layout (need to pass viewport down), bisect into ratio:{first:(size/2), second:(size - first - 1)}, replace with HSplit or VSplit per `dir`. If size after split < MIN cells, return original node + None / propagate error — actually return `Result` from this function. + - `get_pane_direction`: per RESEARCH §"Pattern: Directional Focus" code Example 2 (verbatim). Tie-break: lowest PaneId. + - `nudge_ratio(node, target, dir, min_cells)`: walk down to target's Leaf; on the way up, find the first split whose orientation matches dir's axis (HSplit for Left/Right; VSplit for Up/Down). Shift `ratio.first` by ±1; reject if either would drop below `min_cells`. + - `redistribute(node, new_viewport)`: traverse and proportionally scale each split's `ratio.first` / `ratio.second` to fit the new viewport, but ratchet to integer cells (preserve `first + second + 1 == axis_size`). Plan 04-03 will exercise this when window resize fires. + + 6. **Create `crates/vector-mux/src/mux.rs`** per RESEARCH §"Pattern: Mux::get() Singleton". `Mux::install(mux)` panics on second call; `Mux::get()` returns the Arc or panics if not installed. Key methods: + ```rust + pub fn create_window(&self) -> WindowId { /* allocate + insert empty Window */ } + + /// SYNC method (for Phase-4-internal testability). Plan 04-03 will wrap this in + /// an async helper that drives LocalDomain::spawn_local at call time. + pub fn install_tab(&self, window_id: WindowId, pane: Arc, rows: u16, cols: u16) -> (TabId, PaneId) { + // allocates tab_id; tab.root = Leaf(pane.id); inserts pane into self.panes; pushes Tab into window.tabs. + } + + pub fn split_pane(&self, pane_id: PaneId, dir: SplitDirection, new_pane: Arc, viewport: Rect) + -> Result { /* finds tab containing pane_id; mutates tab.root via split_at_leaf; inserts new_pane into self.panes */ } + + pub fn cycle_tab(&self, window_id: WindowId, dir: Direction) { + // Direction::Right → cycle_next; Direction::Left → cycle_prev.

If tab has other panes: replace HSplit/VSplit ancestor with the sibling subtree → CloseResult::PaneClosed. + // (Also remove pane from self.panes.) + // 3. Else, if window has other tabs: remove this tab; active_tab_id moves to neighbor → CloseResult::TabClosed. + // 4. Else, if mux has other windows: remove this window → CloseResult::WindowClosed. + // 5. Else: remove last window → CloseResult::LastWindowClosed. + // Note: this method does NOT actually shut down the transport (that's Plan 04-03 — pty_actor watches for PaneExited). + // It only mutates the in-memory topology. + } + + pub fn focus_direction(&self, from: PaneId, dir: Direction) -> Option { /* delegates to split_tree::get_pane_direction with the tab + viewport from self.windows */ } + + pub fn nudge_split(&self, focused_pane: PaneId, dir: Direction) -> Result<(), NudgeError> { /* delegates to split_tree::nudge_ratio */ } + + pub fn panes_snapshot(&self) -> Vec<(PaneId, std::os::fd::RawFd, Option)> { /* (id, master_fd, pid) per pane — Plan 04-03 proc_tracker consumes */ } + + pub fn pane(&self, id: PaneId) -> Option> { self.panes.read().get(&id).cloned() } + pub fn locate_pane(&self, id: PaneId) -> Option<(WindowId, TabId)> { /* scan windows */ } + ``` + Constructor: + ```rust + impl Mux { + pub fn new(default_domain: Arc) -> Arc { + Arc::new(Self { + windows: RwLock::new(HashMap::new()), + panes: RwLock::new(HashMap::new()), + ids: IdAllocator::new(), + default_domain, + }) + } + } + ``` + + 7. **`crates/vector-mux/src/lib.rs`** — add `pub mod mux; pub mod window; pub mod tab; pub mod pane; pub mod split_tree;` and re-export the key types: `pub use mux::Mux; pub use window::Window; pub use tab::Tab; pub use pane::{Pane, PaneNode, SplitRatio}; pub use split_tree::{Rect, get_pane_direction, NudgeError};`. Preserve Plan 04-01's exports. + + 8. **Fill the 4 test files** (`mux_topology.rs`, `mux_tab_cycle.rs`, `mux_close_cascade.rs`, `split_tree.rs`) per the `` block. Use a test-helper that constructs `Mux::new(Arc::new(LocalDomain::new()))` directly (NOT `Mux::install` — install is for the app-wide singleton; tests want an isolated Mux per test). For tests requiring Pane construction without spawning a real shell, expose an internal `Pane::new_for_test(...)` constructor that takes a dummy `Box` — easiest: build a tiny `NoopTransport` struct in the test file itself that implements the trait with `async fn` stubs returning empty results. (Use `async-trait` per Plan 02-04.) + + Each test file ends with: + ```rust + // No longer #[ignore]'d — Plan 04-02 implementation. + ``` + + + + cargo test -p vector-mux --test mux_topology --test mux_tab_cycle --test mux_close_cascade --test split_tree 2>&1 | tail -15 + + + - `cargo test -p vector-mux --test mux_topology 2>&1 | grep -E '^test result:'` shows `ok` with at least 2 passes and 0 failures + - `cargo test -p vector-mux --test mux_tab_cycle 2>&1 | grep -E '^test result:'` shows `ok` with at least 3 passes and 0 failures + - `cargo test -p vector-mux --test mux_close_cascade 2>&1 | grep -E '^test result:'` shows `ok` with at least 4 passes and 0 failures + - `cargo test -p vector-mux --test split_tree 2>&1 | grep -E '^test result:'` shows `ok` with at least 4 passes and 0 failures + - `grep -c 'Wave-0 stub: Plan 04-02' crates/vector-mux/tests/mux_topology.rs crates/vector-mux/tests/mux_tab_cycle.rs crates/vector-mux/tests/mux_close_cascade.rs crates/vector-mux/tests/split_tree.rs` returns 0 (no remaining `#[ignore]` markers in the un-ignored files) + - `grep -nE 'pub (struct Mux|enum PaneNode|enum SplitDirection|enum Direction|enum CloseResult|enum SplitError|fn close_pane|fn split_pane|fn cycle_tab|fn focus_direction|fn nudge_split)' crates/vector-mux/src/{mux,pane,ids,split_tree}.rs` returns at least 10 lines + - `grep -n 'static MUX' crates/vector-mux/src/mux.rs` returns 1 line containing `OnceLock>` + - `grep -n 'await_holding_lock' Cargo.toml` confirms the workspace lint is set to deny (Phase 1 wired this); the new code must NOT introduce any await-while-locked patterns — `cargo clippy --workspace --all-targets -- -D warnings` exit 0 + - `cargo fmt --all -- --check` exit 0 + + + Mux singleton, Window/Tab/Pane structs, PaneNode tree, split-at-leaf, close-cascade decision logic, cycle-next/prev, and directional-focus algorithm are all implemented and unit-tested.

The `frame_tick_loop` signature changes from Phase 3 to take a `pane_id: PaneId` and emit `UserEvent::PaneOutput { pane_id, bytes }`. + - **Per-pane actor task:** + - One `JoinSet::spawn`'d task per pane; on transport.wait() completion, emits `UserEvent::PaneExited(pane_id)` then returns the PaneId from the task body. Router can `join_next_exited().await` to learn which pane exited (App side surfaces this as the "[Process completed]" sentinel — that line is added by Plan 04-04 / 04-05; Plan 04-03 just emits the event). + - Verify with a unit test in `pty_actor.rs` (under `#[cfg(test)] mod tests`) that constructs a `NoopTransport` (immediately-Ready wait + reader yielding once-then-EOF) and asserts that PaneExited reaches the proxy. + - **UserEvent enum change is breaking for Phase-3 callers:** + - `crates/vector-app/src/app.rs` references `UserEvent::PtyOutput` and `UserEvent::Resized`. Plan 04-04 owns the full app.rs refactor; Plan 04-03 only changes `main.rs` (the enum + the pty_actor wiring) and adds a temporary back-compat layer: while app.rs is unchanged in this plan, the old PtyOutput/Resized variants are kept as `#[deprecated]` re-export shims that wrap a default PaneId(0) — Plan 04-04 deletes them. + - **Alternative (cleaner):** Plan 04-03 ALSO updates app.rs's `user_event` arms to switch on PaneId (single-pane semantics for now: ignore pane_id, drive the existing single-Term, single-Compositor pipeline). Plan 04-04 then layers multi-pane on top. **Choose this alternative**: cleaner, no shim debt. + - **Mux async helpers:** + - `Mux::create_tab_async(&self, window_id, cwd: Option, rows: u16, cols: u16) -> Result<(TabId, PaneId)>`: calls `self.default_domain.spawn_local(SpawnCommand { argv: None, cwd, rows, cols, env: vec![] }).await?`, constructs `Pane` from `SpawnedPane`, calls `self.install_tab` sync helper from Plan 04-02. **NOTE: Calling spawn_local here means default_domain MUST be `Arc` (concrete) not `Arc`. Plan 04-02 already encodes this. Phase 7 will add a parallel `create_tab_with_domain_async(domain: Arc, ...)` that uses the trait method `Domain::spawn` and a SECOND construction path for `SpawnedPane` (the `pid` + `master_fd` will be None for non-local domains — that's fine).** + - `Mux::split_pane_async(&self, pane_id, dir, cwd: Option) -> Result`: looks up parent pane's pid, calls `inherit_cwd(parent.pid)` if cwd is None, spawns new pane, mutates tree via `split_at_leaf` (Plan 04-02 sync helper). + - `Mux::resize_window(&self, window_id, rows: u16, cols: u16) -> Vec<(PaneId, u16, u16)>`: walks each tab, calls `split_tree::redistribute(&mut tab.root, Rect{x:0,y:0,w:cols,h:rows})`, then returns the per-pane (PaneId, new_rows, new_cols) tuples for the App to relay through `router.send_resize`. + - **proc_tracker spawn:** + - `crates/vector-app/src/main.rs` spawns `proc_name_poll_loop(proxy.clone())` once on startup (after Mux::install). The loop runs forever; tasks are cheap. + + + 1. **`crates/vector-mux/Cargo.toml`** — ensure `libc.workspace = true` is present (for `tcgetpgrp`). If `libc` isn't in `[workspace.dependencies]`, add it: `libc = "0.2"`. + + 2. **Create `crates/vector-mux/src/cwd.rs`** — implement `inherit_cwd` per ``. Add a `cfg(test)` mod that injects `home: Option<&str>` via a private `inherit_cwd_with(parent_pid, home_env)` seam so tests can drive the fallback chain deterministically. Re-export `inherit_cwd` at crate root via `pub use cwd::inherit_cwd;` in lib.rs. + + 3. **Create `crates/vector-mux/src/proc_tracker.rs`** — implement `proc_name_poll_loop(proxy)` per ``. Use `tokio::time::interval(Duration::from_secs(1))` with `MissedTickBehavior::Skip` (RENDER-03 — tracker must not contribute to wakeups). Add a `pub fn spawn_proc_tracker(proxy: EventLoopProxy) -> tokio::task::JoinHandle<()>` helper. The loop guards against `master_fd == -1` and `pgrp < 0` (closed/invalid). Reference: 04-RESEARCH §"Pattern: Foreground-Process Tracking" (verbatim). + + 4. **`crates/vector-mux/src/mux.rs`** — add async methods per ``. `create_tab_async` calls `self.default_domain.spawn_local(...)`. The `default_domain` field stays `Arc` (concrete). Implement `resize_window` that walks tabs, calls `split_tree::redistribute`, returns per-leaf `(PaneId, rows, cols)`. **Discipline:** never `.await` while holding `self.windows.write()` or `self.panes.write()` (Pitfall B). The `spawn_local` await happens BEFORE the write-lock is taken; the write-lock is then taken to insert. + + 5. **`crates/vector-mux/src/pane.rs`** — verify `take_transport()` works as Plan 04-02 specified. Add `Pane::shell_pid() -> Option` (just returns self.pid). Add `Pane::master_fd() -> RawFd` (returns self.master_fd). + + 6. **`crates/vector-mux/src/lib.rs`** — `pub mod cwd; pub mod proc_tracker;` + `pub use cwd::inherit_cwd; pub use proc_tracker::{proc_name_poll_loop, spawn_proc_tracker};`. + + 7. **`crates/vector-app/src/main.rs`** — replace the `UserEvent` enum with the Phase-4 form per ``. (DELETE `PtyOutput(Vec)` and `Resized { rows, cols }` — replaced by `PaneOutput` and `PaneResized`.) Wire up bootstrap: + ```rust + // After tokio runtime is built and proxy is available: + let local_domain = Arc::new(vector_mux::LocalDomain::new()); + let mux = vector_mux::Mux::new(local_domain); + vector_mux::Mux::install(Arc::clone(&mux)); + + // Bootstrap window + tab + pane: + let window_id = mux.create_window(); + let (tab_id, pane_id) = mux.create_tab_async(window_id, None, 24, 80).await?; + + // Construct router; spawn the first pane's actor: + let mut router = PtyActorRouter::new(proxy.clone()); + if let Some(pane) = mux.pane(pane_id) { + if let Some(transport) = pane.take_transport() { + router.spawn_pane(pane_id, transport); + } + } + + // Spawn proc-tracker (D-57): + vector_mux::spawn_proc_tracker(proxy.clone()); + ``` + Note: the bootstrap pane spawn is the SINGLE happy-path; subsequent Cmd-T / Cmd-D paths run in Plan 04-04's app.rs handlers. + + 8. **`crates/vector-app/src/pty_actor.rs`** — REWRITE per ``. Keep the existing helper functions if any are still applicable, but the public surface is now `PtyActorRouter` (struct) + `spawn_pane` + `send_write` + `send_resize` + `coalesce_buffer` + `join_next_exited`. The internal `pane_io_loop` is private (per-pane task body). Add `#[cfg(test)] mod tests` with one unit test that uses a hand-rolled `NoopTransport` to assert PaneExited reaches the proxy. + + 9. **`crates/vector-app/src/frame_tick.rs`** — change `frame_tick_loop` signature to `(pane_id: PaneId, coalesce: Arc, proxy: EventLoopProxy, lpm: Arc)`. The emit becomes `UserEvent::PaneOutput { pane_id, bytes }`. Caller (`PtyActorRouter::spawn_pane`) spawns one per pane. + + 10. **`crates/vector-app/src/app.rs`** — update `user_event` arms to match the new enum. For Plan 04-03, treat `PaneOutput { pane_id, bytes }` as the only pane (drive the single Term that Phase 3 wired). The Plan 04-04 refactor will look up the right `Pane` from Mux. For now: ignore pane_id (`let _ = pane_id;`) and pipe bytes into the existing `Arc>` — Phase-3 single-pane semantics, just renamed event variants.

Build a sync `Mux::new(Arc::new(LocalDomain::new()))` (NOT install — test-isolated). + 2. `create_tab_async(window_id, Some(env::current_dir()?), rows=24, cols=80).await` → (tab, p1). + 3. Take p1's transport via `pane.take_transport()`. + 4. Write `tput cols\n` into the transport, read output until newline, parse — assert ~80. + 5.

(`tput` uses `TIOCGWINSZ` ioctl which the kernel updated when `transport.resize` set it. CORE-04 reuse from Plan 02-03.) + 7. Now test the SPLIT path: `split_pane_async(p1, SplitDirection::Horizontal, None).await` → p2; resize_window again to 24x80 — both panes get (24, ~40) per redistribute; `tput cols` in each pane reports its share. + + - **proc_name_tracking.rs:** + 1.

The tput-cols read is the same shape Plan 02-03 used (poll-read until newline; trim; parse). + + 2. **Fill `crates/vector-mux/tests/proc_name_tracking.rs`** — see ``. Avoid spawning the actual `proc_name_poll_loop` (it needs an EventLoopProxy); instead exercise the *primitives* (`libc::tcgetpgrp` + `libproc::pidpath`) directly in the test loop. This isolates the assertion from winit. Cite the parallel: `proc_name_poll_loop` is mechanically the same code path. `#[ignore]` flagged. + + 3. **Fill `crates/vector-mux/tests/cwd_inheritance.rs`** per ``. After writing `cd /tmp` is NOT necessary if the test sets `cwd: Some(PathBuf::from("/tmp"))` at spawn — but the split test (#3 in the behavior block) must rely on `libproc::pidcwd` reading the live child's cwd, which is what we're really testing. `#[ignore]` flagged. + + 4. **Run each test:** + ```bash + cargo test -p vector-mux --test pane_resize_propagates -- --include-ignored + cargo test -p vector-mux --test proc_name_tracking -- --include-ignored + cargo test -p vector-mux --test cwd_inheritance -- --include-ignored + ``` + All three must pass.

Every WindowEvent first looks up the TabWindow by `event.window_id`. The "active" tab is whichever NSWindow is keyWindow per macOS (winit reports `WindowEvent::Focused(true)` as the active-tab signal). + - **Cmd-T handler:** `WindowAttributes::default() .with_title("Vector") .with_inner_size(LogicalSize::new(1024.0, 640.0))`; `event_loop.create_window(attrs)?`; **CRITICAL** call `winit::platform::macos::WindowExtMacOS::set_tabbing_identifier(&new_win, "com.vector.terminal")`; allocate Mux WindowId + TabId + first PaneId via `mux.create_window()` + `mux.create_tab_async(window_id, inherited_cwd, rows, cols).await`; hand pane's transport to the router; insert TabWindow into App.windows. **Pitfall E fallback:** if winit-issue-#2238 reproduces (first Cmd-T creates a separate NSWindow not in the tab group), the executor must call objc2-app-kit's `setTabbingMode:` directly after window creation. This is a runtime detection: there's no clean way to test #2238 in CI; the Plan 04-05 manual smoke matrix item #1 verifies. If the executor wants to belt-and-braces it: ALWAYS call objc2-app-kit's `setTabbingMode(NSWindowTabbingModePreferred)` on every window in addition to `set_tabbing_identifier`. + - **Cmd-D / Cmd-Shift-D handler:** `mux_commands.rs::handle_mux_command(app, MuxCommand::SplitHorizontal)` calls `app.mux.split_pane_async(active_pane, SplitDirection::Horizontal, None).await?` → returns new PaneId; hand new pane's transport to router; insert a new Compositor for the new pane into the active TabWindow's `compositors: HashMap`; recompute pane viewport rectangles via `split_tree::compute_layout` and call `set_viewport` on each Compositor; request_redraw on the TabWindow's winit Window. + - **Cmd-Opt-Arrow handler:** `MuxCommand::FocusDir(dir)` → `mux.focus_direction(active_pane, dir)` → if Some(new_id), update `tab.active_pane_id`, call `set_border_color([0,0,0,0])` on old pane's compositor, `set_border_color(accent)` on new, request_redraw (RESEARCH Open Question #4). + - **Cmd-Shift-Arrow handler:** `MuxCommand::NudgeSplit(dir)` → `mux.nudge_split(active_pane, dir)` → recompute viewports + redraw. + - **Cmd-W handler:** `MuxCommand::ClosePane` → `mux.close_pane(active_pane) -> CloseResult` then: + - `PaneClosed { tab_id }`: drop the closed-pane's Compositor from the TabWindow; recompute viewports for remaining panes; request_redraw. + - `TabClosed { window_id }`: drop the corresponding TabWindow from `app.windows` (which drops the winit Window — AppKit removes it from the tab group); if `app.windows.is_empty()` after the drop, `event_loop.exit()`. + - `WindowClosed { window_id }`: same drop semantics. + - `LastWindowClosed`: `event_loop.exit()`. + - **Cmd-Shift-]/[ handler:** `MuxCommand::CycleTabNext/Prev` → on macOS, the canonical way is to call winit's `select_next_tab()` / `select_previous_tab()` on the focused window — that's an OS-level NSWindow operation that animates the tab switch. ALSO update `mux.cycle_tab(window_id, ...)` to keep mux's `active_tab_id` in sync. (If winit's `select_next_tab` isn't directly available, fall back to objc2-app-kit `NSWindow::tabGroup().setSelectedWindow(...)` against the next NSWindow in the tab group.) + - **Compositor per-pane:** TabWindow holds `compositors: HashMap`. Each Compositor has its own viewport offset + size. On `WindowEvent::RedrawRequested`: + ```rust + // Acquire surface texture once: + let frame = host.surface.get_current_texture()?; + let view = frame.texture.create_view(...); + // Render each compositor in turn: + let mut load_op = LoadOp::Clear(bg_color); + for (pane_id, compositor) in &mut tab_window.compositors { + let pane = mux.pane(*pane_id); + if let Some(pane) = pane { + let mut term = pane.term.lock(); + let selection = /* active pane only */; + compositor.render(&mut term, selection, load_op)?; + load_op = LoadOp::Load; // subsequent compositors don't clear + } + } + frame.present(); + ``` + - **Active pane border (D-66):** the active pane's compositor calls `set_border_color([0.4, 0.6, 1.0, 1.0])`; others set `[0,0,0,0]`. cell.wgsl Uniforms gain `border_color` + `viewport_offset_px` + `border_width_px`; fragment shader: compute pixel position in viewport (`abs(frag_pos - viewport_center)`), check distance to viewport edge in pixels; if within border_width AND border_color.a > 0, replace output with border_color. + - **Inactive cursor (Claude's Discretion):** cursor.wgsl gains `cursor_focused: u32`; when 0, draw stroke (outline) instead of filled rect — vertex shader generates the outline geometry or the fragment shader masks the interior. + - **First-paint gate per TabWindow:** `TabWindow.first_paint_ready` flips on first non-empty PaneOutput drain for any pane in this tab; before that, RedrawRequested early-returns (don't render); overlay drops at the same moment (per-window overlay). + - **active_pane_border.rs offscreen test:** construct a `RenderContext::new_offscreen`, two Compositors at viewports (0,0,400,600) and (400,0,400,600), set border_color on the first to `[1.0, 0.0, 0.0, 1.0]` (red), render both; read pixels along the left edge of viewport 1 → assert majority are red within tolerance; assert viewport 2 has NO red border. + - **multi_window_tabbing.rs mock test:** Trait-route `set_tabbing_identifier` via a `WindowTabbingExt` trait that the production code uses; the test provides a mock impl that records calls. Assert: after the App's Cmd-T handler runs (use a test-only `App::handle_mux_command_in_test(MuxCommand::NewTab)` entry point — or extract the body of the handler into a free function `create_tabbed_window(event_loop, mux, router, attrs) -> Result` that the test can drive against a mock event-loop-shim. Visual NSWindow grouping is manual-only (smoke matrix #1); this test ONLY asserts the API call happens. + + + 1. **Workspace deps:** verify `crates/vector-app/Cargo.toml` already has `objc2-app-kit.workspace = true` (Phase 1 wired it). If not, add it. Same for `objc2-foundation`. + + 2. **Create `crates/vector-app/src/tab_window.rs`** with the struct per ``. Add `TabWindow::new(window_id, tab_id, winit_window, render_host) -> Self`. Add `TabWindow::insert_compositor(pane_id, compositor)`, `take_compositor(pane_id)`, `recompute_viewports(tab: &Tab)` (calls `split_tree::compute_layout(&tab.root, viewport_rect)` and calls `set_viewport` on each Compositor). + + 3. **Create `crates/vector-app/src/mux_commands.rs`** with `pub async fn handle_mux_command(app: &mut App, cmd: MuxCommand) -> Result<()>`. Body switches on `cmd` and implements each of the 8 paths per ``. The function CAN be async (the App is built around tokio LocalSet for main-thread tasks — alternative: dispatch the async work to the I/O runtime via the proxy + a "DoMuxAction" UserEvent variant). **Cleaner pattern:** mux_commands.rs has a sync entry point that spawns the async work on the tokio runtime via `tokio::spawn`, and a UserEvent::MuxCommandCompleted(MuxCommandOutcome) routes the result back to the main thread for state updates (winit Window create/drop must happen on main). Pick the pattern that fits the existing app.rs threading model; document the choice in SUMMARY. + + 4. **`crates/vector-app/src/app.rs`** — major refactor: + - `App` struct: replace `window: Option>`, `term: Arc>`, `render_host: Option` with `windows: HashMap`, `router: PtyActorRouter`, `mux: Arc`, `input_bridge: InputBridge`, `lpm_enabled: Arc`. + - `App::resumed`: bootstrap window via `mux.create_window()` + `mux.create_tab_async(...)` + `set_tabbing_identifier("com.vector.terminal")` + register first pane's actor. + - `WindowEvent::KeyboardInput` handler: call `encode(...)` → match on EncodedKey: `Pty(bytes)` → `router.send_write(active_pane_id_for_window, bytes)`; `Mux(cmd)` → dispatch to `handle_mux_command(self, cmd)`. + - `WindowEvent::Resized`: lookup TabWindow; store pending_resize + last_resize_at; debounce same as Plan 03-05 (50ms quiescence) before calling `mux.resize_window(window_id, rows, cols)` and routing per-pane resize via router.send_resize. + - `WindowEvent::Focused(true)`: track which TabWindow's NSWindow is keyWindow. + - `WindowEvent::CloseRequested`: handle native close button — call close_pane cascade against the focused pane (or close the whole tab). + - `user_event(UserEvent::PaneOutput { pane_id, bytes })`: feed into `mux.pane(pane_id).term.lock().feed(&bytes)`; mark the TabWindow's first_paint_ready true; request_redraw on the window containing that pane. + - `user_event(UserEvent::PaneExited(pane_id))`: append a `\r\n[Process completed]\r\n` to that pane's term (Claude's Discretion: "exited" sentinel); mark `pane.exited = true`; do NOT auto-close (user uses Cmd-W). + - `user_event(UserEvent::PaneTitleChanged { pane_id, label })`: lookup the TabWindow containing that pane; if pane_id is the active pane of its tab AND the tab is active in its window, call `winit_window.set_title(&format!("{}: {}", mux.pane(pane_id).domain_label, label))`. D-58 hook: `domain_label` is `"Local"` for Phase 4; Phase 7 will swap to `"☁ codespace-name"`. + - `user_event(UserEvent::PaneResized { pane_id, .. })`: log; no further action (the pane's Term::resize already ran when the App emitted the resize through `mux.resize_window`). + + 5. **`crates/vector-app/src/menu.rs`** — enable File→New Tab (Cmd-T) and File→Close (Cmd-W) menu items (Phase 1 D-15 installed them disabled). Add menu items for Cmd-D / Cmd-Shift-D / Cmd-Shift-]/[ under a new "Pane" or "View" menu — match macOS conventions. The menu click handlers should send the same MuxCommand into the App via `proxy.send_event(UserEvent::MuxCommandFromMenu(MuxCommand::NewTab))` or by directly emitting the same key sequence (avoid plumbing complexity). Pick the simpler path: menu items emit UserEvent variants that `user_event` dispatches to `handle_mux_command`. + + 6. **`crates/vector-app/src/input_bridge.rs`** — selection state is per-pane now. Either: (a) move selection state into `Pane` (vector-mux); (b) keep a `HashMap` in InputBridge. Pick (b) for less churn: `InputBridge { selections: HashMap, ... }`; lookups by active_pane_id. + + 7. **`crates/vector-render/src/compositor.rs`** — add the `viewport_offset_px`, `viewport_size_px`, `border_color`, `border_width_px`, `cursor_focused` fields. Add `set_viewport`, `set_border_color`, `set_cursor_focused`, `new_with_viewport`. The `render(...)` method gains a `load_op: wgpu::LoadOp` parameter. The fragment shader gets the new uniforms via the `Uniforms` struct on the bind group. + + 8. **`crates/vector-render/src/cell_pipeline.rs`** — extend the `Uniforms` struct in Rust + write to the uniform buffer per frame. The wgsl Uniforms struct must match byte-for-byte (alignment: vec4 = 16, vec2 = 8, f32 = 4; pad to 16 boundaries — the existing `_pad: f32` slot must be re-purposed and a new pad added if the new fields shift alignment). + + 9. **`crates/vector-render/src/shaders/cell.wgsl`** — extend `Uniforms` struct + add the edge-distance test in `fs_main`. Pseudo-code: + ```wgsl + let local_pos = frag_pos.xy - uniforms.viewport_offset_px; + let dist_l = local_pos.x; + let dist_r = uniforms.viewport_size_px.x - local_pos.x; + let dist_t = local_pos.y; + let dist_b = uniforms.viewport_size_px.y - local_pos.y; + let dist_to_edge = min(min(dist_l, dist_r), min(dist_t, dist_b)); + if (dist_to_edge < uniforms.border_width_px && uniforms.border_color.a > 0.0) { + return uniforms.border_color; + } + // existing fg/bg/atlas blend follows + ``` + + 10. **`crates/vector-render/src/cursor_pipeline.rs` + `cursor.wgsl`** — add `cursor_focused: u32` uniform. wgsl: when `cursor_focused == 0u`, the fragment shader checks proximity to the cursor cell's edge (within 1 px) — pixels inside the cell but >1px from the edge become transparent (`return vec4(0,0,0,0);`), creating a stroke. When `cursor_focused != 0u`, render the existing filled rect. + + 11. **Fill `crates/vector-render/tests/active_pane_border.rs`** per ``. Use Plan 03-03's `RenderContext::new_offscreen` + `Compositor::new_with` style — extended to `new_with_viewport`. Render twice with `LoadOp::Clear` then `LoadOp::Load`.

Three options were considered: + +1. **Extend the Domain trait** (e.g., return `(Box, Option, Option)` or a struct). Rejected: Phase 7 CodespaceDomain inherently has no local pid/fd; the trait would need an `Option<...>` shape that's only meaningful for `LocalDomain`. D-38 was locked as "Phases 7/8/9 fill bodies, not reshape". +2. **Downcast `&dyn PtyTransport` to `&LocalTransport`** at the Mux call site. Rejected: `Any` + `downcast_ref` against a trait-object adds runtime cost and clippy noise; also fails for Phase 7 transports. +3. **Add an inherent method on LocalDomain that returns SpawnedPane, separate from the trait method.** Adopted. The trait `Domain::spawn` stays D-38-final; Mux call sites that need local-specific data call `LocalDomain::spawn_local` directly (it's a non-trait method on the concrete type). Codespace/DevTunnel will follow the same pattern in Phase 7/8 with their own `spawn_codespace` / `spawn_dev_tunnel` equivalents — each returning a SpawnedPane with `pid: None` and `master_fd: None`. + +This preserves CONTEXT.md D-67's "never touches the traits" promise. + +## LocalPty Field-Touchpoint Notes for Plan 04-03 + +While wiring `child_pid()` + `master_raw_fd()`: + +- **`MasterPty::as_raw_fd()` returns `Option`**, not bare `RawFd`. Documented in portable-pty 0.9.0's `lib.rs:114`: "If get_termios() and process_group_leader() are both implemented and return Some, then as_raw_fd() should return the same underlying fd". On macOS / Unix native PTY this returns Some; on platforms without a Unix fd it returns None. **Plan 04-03 should handle `master_fd: None` as a tracking-impossible state (trace-log, fall back to "shell" as the process name).** +- **`Child::process_id()` returns `Option`** that becomes None after `Child::wait()` consumes the child. **Plan 04-03's polling loop should re-check pid each tick** — pid going None means the pane exited and the foreground-process tracker should stop polling for that pane. +- **`LocalPty.child` is `Option>`** (not bare Box) because `wait()` does `self.child.take()`. The new `child_pid()` accessor reads `self.child.as_ref().and_then(|c| c.process_id())` to gracefully handle the post-wait state. +- **No new `child_pid: Option` cached field added on LocalPty.** The plan's Task 1 step 3 suggested "if `child` is wrapped in `Mutex`, pull the pid out at spawn time and cache it". Since `child` is just `Option>` (no Mutex), the as_ref() path is fine. **Plan 04-03 can rely on `child_pid()` being cheap to call.** + +## Decisions Made + +- **`SpawnedPane.master_fd: Option` instead of bare `RawFd` (plan's `` sketch).** Forced by portable-pty's `MasterPty::as_raw_fd() -> Option` underlying signature. Returning Option upstream is cleaner than `expect()`ing in `spawn_local`; Plan 04-03's call sites will short-circuit on None. +- **`SpawnedPane.pid: Option` for symmetry with the Codespace/DevTunnel future** (which have no local PID); also lets the field gracefully reflect post-`wait()` state. +- **`LocalDomain::spawn_local` kept as `async fn`** (with `#[allow(clippy::unused_async)]`) to mirror `Domain::spawn`'s signature. Phase 7's `CodespaceDomain::spawn_*` equivalent will be truly async (network calls). Keeping `spawn_local` async maintains call-site symmetry. +- **No refactor of `Domain::spawn` to delegate to `spawn_local`.** The plan said optional; we kept the existing impl byte-identical to minimize risk to Plan 02-04's 8 `trait_object_safety.rs` tests. The two methods duplicate ~5 lines of `PtySpawnCommand` construction and `Box::new(LocalTransport(pty))` — acceptable. +- **`IdAllocator` is a single shared `AtomicU64` for now.** The plan called out per-kind counters as a Plan-04-02 refinement; current shape gives "ID-N is the Nth allocation regardless of kind" semantics, which is sufficient for compile-time wiring. + +## Task Commits + +1. **Task 1: Workspace + crate deps + LocalPty/LocalDomain extension + SpawnedPane** — `d7d5b94` (feat) +2. **Task 2: Seed 12 Wave-0 stub files + 14 Cmd-* keymap stubs + WIN-04 grep** — `75ac3d3` (test) + +## Files Created/Modified + +### Created (15) + +- `crates/vector-mux/src/ids.rs` +- `crates/vector-mux/src/spawned_pane.rs` +- `crates/vector-mux/tests/mux_topology.rs` +- `crates/vector-mux/tests/mux_tab_cycle.rs` +- `crates/vector-mux/tests/mux_close_cascade.rs` +- `crates/vector-mux/tests/split_tree.rs` +- `crates/vector-mux/tests/directional_focus.rs` +- `crates/vector-mux/tests/split_resize_nudge.rs` +- `crates/vector-mux/tests/pane_resize_propagates.rs` +- `crates/vector-mux/tests/proc_name_tracking.rs` +- `crates/vector-mux/tests/cwd_inheritance.rs` +- `crates/vector-mux/tests/cwd_fallback.rs` +- `crates/vector-term/tests/no_transport_discrimination.rs` +- `crates/vector-render/tests/active_pane_border.rs` +- `crates/vector-app/tests/multi_window_tabbing.rs` + +### Modified (6 + Cargo.lock) + +- `Cargo.toml` — added `libproc = "0.14"` to `[workspace.dependencies]` +- `crates/vector-mux/Cargo.toml` — added `libproc.workspace = true` + `parking_lot.workspace = true` +- `crates/vector-mux/src/lib.rs` — added `pub mod ids; pub mod spawned_pane;` + re-exports +- `crates/vector-mux/src/local_domain.rs` — added inherent `spawn_local` method +- `crates/vector-pty/src/local.rs` — added `child_pid()` + `master_raw_fd()` accessors +- `crates/vector-input/tests/xterm_key_table.rs` — appended 14 Cmd-* stub cases +- `Cargo.lock` — libproc 0.14.11 + transitive deps resolved + +## Deviations from Plan + +### Auto-fixed Issues + +**1.

The returned `SpawnedPane { transport, pid, master_fd }` is the input to `Pane::new(id, term, transport, pid, master_fd)`. +- **Call `Pane::take_transport()` exactly once** when handing the transport to your pty_actor. Subsequent `take_transport()` calls return None — guard against double-take in your router. +- **`Mux::panes_snapshot() -> Vec<(PaneId, Option, Option)>`** is the proc_tracker input. Snapshot is cheap (read lock + clone of 3-tuples). 1Hz polling per RESEARCH.md. +- **The cwd inheritance call site is `Mux::create_tab` / `Mux::split_pane`** (when you wire them via `LocalDomain::spawn_local`). For Plan 04-03 you'll add an async helper like `Mux::create_tab_async(window_id, cwd) -> Result<(TabId, PaneId)>` that calls `inherit_cwd(parent_pane) -> PathBuf` (libproc::pidcwd with $HOME fallback) before spawning. +- **Window resize**: when the App's `WindowEvent::Resized` fires, call `Mux::with_tab` (or add a `resize_tab(window_id, tab_id, new_rows, new_cols)` method) to update `Tab.last_rows/last_cols` and call `split_tree::redistribute(&mut tab.root, new_viewport)` to scale split ratios. Then iterate the new layout and call `transport.resize(rows, cols, 0, 0)` on each pane's pty_actor channel. +- **D-38 still intact**: do not modify `crates/vector-mux/src/domain.rs` or `crates/vector-mux/src/transport.rs`. If Plan 04-03 needs a new transport-agnostic capability, add it to the `PtyTransport` trait surface ONLY if it's universally meaningful (Local + Codespace + DevTunnel). For pid/master_fd-specific things, use the inherent method pattern that Plan 04-01 established (`LocalDomain::spawn_local`). + +## Decisions Made + +1. **Per-kind ID counters** vs Plan 04-01's single shared AtomicU64. Tests assert `PaneId(1)` for the first allocation regardless of preceding tab/window calls. Single shared counter would make test setup brittle (e.g., `mux.create_window(); mux.allocate_pane_id()` would yield PaneId(2)). `#[allow(clippy::struct_field_names)]` on `IdAllocator` keeps `next_pane`/`next_tab`/`next_window` field naming. +2. **SplitRatio bisect favors `first` on odd sizes.** 80 → first=40, second=39. Matches WezTerm's `first.cells = total / 2; second.cells = total - first.cells - divider`. +3. **`split_pane` on failed bisect restores `Tab.root = Leaf(pane_id)`** rather than trying to undo the `mem::replace`. Practically all callers pre-check viable size; this is defense in depth. The unit test `split_below_minimum_size_is_rejected` exercises only the algorithm (`split_at_leaf`), not the Mux wrapper, because the algorithm test reads cleaner without setting up a full Mux. +4. **`close_pane` cascade is single-pass.** Within one RwLock write guard: try collapse-within-tab → drop tab if empty → drop window if last tab → cascade to LastWindowClosed if last window. The pane is removed from `panes` HashMap after the topology mutation completes. No two-phase commit needed; CloseResult tells the App layer what side-effects to perform. +5. **Pane.transport `Mutex>>` over `Option>` directly.** The Mutex lets Plan 04-03's pty_actor router take ownership without holding `&mut Pane`. `parking_lot::Mutex` lock held synchronously (microseconds); never across .await (D-11 + workspace `clippy::await_holding_lock = "deny"`). +6. **Test helper module `tests/common/mod.rs`** for shared `NoopTransport` + `make_pane` helpers. 4 test files reference the helper via `mod common;`. Cargo handles non-target `tests/common/` modules correctly via the "common code in tests/" convention. +7. **WIN-04 negative meta-test uses std::env::temp_dir** instead of pulling in `tempfile` as a new dev-dep. Cleanup uses `std::fs::remove_dir_all` at function entry + exit. Process-id suffix on the dir name avoids collisions if the test runs in parallel. +8. **`Tab` struct fields are public** so directional_focus.rs and split_resize_nudge.rs tests construct `Tab` directly. This is the standard Rust pattern for "data class" types — no defensive encapsulation when the data is the whole point. +9. **`get_pane_direction` takes `&Tab`** rather than `&PaneNode + viewport` so the function can use `tab.last_rows`/`tab.last_cols` for the viewport. Mux::focus_direction passes the looked-up tab. +10. **Nudge axis matching uses `axis_h = matches!(dir, Direction::Left | Direction::Right)`.** HSplit owns L/R nudges; VSplit owns U/D. Inner-subtree walk-down happens first; if no matching ancestor lower in the tree, the current split tries; if it doesn't match the axis either, propagate `NudgeOutcome::NotFound` up to the next level. + +## Deviations from Plan + +### Auto-fixed Issues + +**1.

actor per pane (resize > write > read); join_next surfaces PaneExited without a centralized pump (Pitfall C avoidance). - frame_tick_loop now per-pane: takes PaneId + emits UserEvent::PaneOutput {pane_id, bytes}. - UserEvent migrated: PtyOutput / Resized -> PaneOutput / PaneResized; added PaneExited(PaneId) + PaneTitleChanged { pane_id, label }. - vector-mux::cwd::inherit_cwd(parent_pid) with libproc::pidcwd -> $HOME -> / fallback chain (D-63 / D-64); test seam inherit_cwd_with(pid, home) for unit tests. - vector-mux::proc_tracker::proc_name_poll_loop generic over a FnMut(PaneId, String) callback so vector-mux stays free of winit deps; vector-app bridges to EventLoopProxy::send_event(PaneTitleChanged). - Mux::create_tab_async / split_pane_async drive LocalDomain::spawn_local; the .await precedes any RwLock write (Pitfall B); split inherits cwd via inherit_cwd(parent.shell_pid()) when caller passes None. - Mux::resize_window walks each tab, calls split_tree::redistribute, returns the new per-pane (rows, cols) for the App to relay through PtyActorRouter::send_resize (CORE-04 reuse). - Pane gains shell_pid() and master_fd() accessors. - Workspace dep: libc 0.2 added for tcgetpgrp. - cwd_fallback.rs un-ignored (4 passing unit tests). - Workspace test count 201 -> 211 (+10: 4 cwd_fallback + 4 cwd unit + 2 pty_actor unit). --- Cargo.lock | 2 + Cargo.toml | 1 + crates/vector-app/Cargo.toml | 1 + crates/vector-app/src/app.rs | 17 +- crates/vector-app/src/frame_tick.rs | 17 +- crates/vector-app/src/main.rs | 89 ++++++++-- crates/vector-app/src/pty_actor.rs | 217 +++++++++++++++++++----- crates/vector-mux/Cargo.toml | 1 + crates/vector-mux/src/cwd.rs | 68 ++++++++ crates/vector-mux/src/lib.rs | 4 + crates/vector-mux/src/mux.rs | 111 +++++++++++- crates/vector-mux/src/pane.rs | 12 ++ crates/vector-mux/src/proc_tracker.rs | 74 ++++++++ crates/vector-mux/tests/cwd_fallback.rs | 33 +++- 14 files changed, 576 insertions(+), 71 deletions(-) create mode 100644 crates/vector-mux/src/cwd.rs create mode 100644 crates/vector-mux/src/proc_tracker.rs diff --git a/Cargo.lock b/Cargo.lock index 11e95e5..f3dfc3a 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -2310,6 +2310,7 @@ name = "vector-app" version = "2026.5.10" dependencies = [ "anyhow", + "async-trait", "bytes", "cargo-husky", "objc2 0.6.4", @@ -2397,6 +2398,7 @@ version = "2026.5.10" dependencies = [ "anyhow", "async-trait", + "libc", "libproc", "parking_lot", "thiserror 2.0.18", diff --git a/Cargo.toml b/Cargo.toml index 08b173c..f69a53b 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -34,6 +34,7 @@ bytemuck = { version = "1", features = ["derive"] } bytes = "1" crossfont = "0.9" etagere = "0.2" +libc = "0.2" libproc = "0.14" objc2 = "0.6.4" objc2-app-kit = "0.3" diff --git a/crates/vector-app/Cargo.toml b/crates/vector-app/Cargo.toml index e78ec9b..c3b92b9 100644 --- a/crates/vector-app/Cargo.toml +++ b/crates/vector-app/Cargo.toml @@ -32,6 +32,7 @@ vector-render = { path = "../vector-render" } vector-term = { path = "../vector-term" } [dev-dependencies] +async-trait = { workspace = true } cargo-husky = { version = "1", default-features = false, features = ["user-hooks"] } [lints] diff --git a/crates/vector-app/src/app.rs b/crates/vector-app/src/app.rs index 383bde3..40a2dc2 100644 --- a/crates/vector-app/src/app.rs +++ b/crates/vector-app/src/app.rs @@ -109,7 +109,9 @@ impl ApplicationHandler for App { fn user_event(&mut self, _event_loop: &ActiveEventLoop, event: UserEvent) { match event { - UserEvent::PtyOutput(bytes) => { + UserEvent::PaneOutput { pane_id, bytes } => { + // Plan 04-03 shim: single-pane semantics — Plan 04-04 routes by PaneId. + let _ = pane_id; if bytes.is_empty() { return; } @@ -128,13 +130,24 @@ impl ApplicationHandler for App { } self.request_redraw(); } - UserEvent::Resized { rows, cols } => { + UserEvent::PaneResized { + pane_id, + rows, + cols, + } => { + let _ = pane_id; { let mut t = self.term.lock(); t.resize(cols, rows); } self.request_redraw(); } + UserEvent::PaneExited(pane_id) => { + tracing::info!(?pane_id, "pane exited (Plan 04-04 will render sentinel)"); + } + UserEvent::PaneTitleChanged { pane_id, label } => { + tracing::info!(?pane_id, %label, "pane title changed (Plan 04-04 will route to tab)"); + } UserEvent::LpmChanged(enabled) => { self.lpm_flag.store(enabled, Ordering::Relaxed); } diff --git a/crates/vector-app/src/frame_tick.rs b/crates/vector-app/src/frame_tick.rs index ad8baf2..4b0e188 100644 --- a/crates/vector-app/src/frame_tick.rs +++ b/crates/vector-app/src/frame_tick.rs @@ -10,6 +10,7 @@ use bytes::BytesMut; use parking_lot::Mutex; use tokio::sync::Notify; use tokio::time::{interval, MissedTickBehavior}; +use vector_mux::PaneId; use winit::event_loop::EventLoopProxy; use crate::UserEvent; @@ -71,10 +72,12 @@ pub fn frame_period_ms(lpm: &Arc) -> u64 { } } -/// Frame-tick loop: drains the coalesce buffer every ~8 ms (or ~33 ms under LPM) -/// and emits exactly one `PtyOutput` per non-empty drain.

Rule 1 fix [auto]: libproc 0.14's pidcwd is documented as "not implemented for macos" — we ship a vector_mux::cwd::pidcwd shim that calls Darwin proc_pidinfo with PROC_PIDVNODEPATHINFO directly (on Linux delegates to libproc). The shim is cfg(target_os) gated; one extra unit test (pidcwd_of_self_matches_current_dir) exercises it without needing real-PTY integration. --- crates/vector-mux/Cargo.toml | 2 + crates/vector-mux/src/cwd.rs | 79 +++++++++- crates/vector-mux/tests/cwd_inheritance.rs | 53 +++++-- .../tests/pane_resize_propagates.rs | 146 ++++++++++++++++-- crates/vector-mux/tests/proc_name_tracking.rs | 109 +++++++++++-- 5 files changed, 354 insertions(+), 35 deletions(-) diff --git a/crates/vector-mux/Cargo.toml b/crates/vector-mux/Cargo.toml index a3cdf5b..f788bdb 100644 --- a/crates/vector-mux/Cargo.toml +++ b/crates/vector-mux/Cargo.toml @@ -21,6 +21,8 @@ vector-term = { path = "../vector-term", version = "2026.5.10" } [dev-dependencies] anyhow = { workspace = true } async-trait = { workspace = true } +libc = { workspace = true } +libproc = { workspace = true } parking_lot = { workspace = true } tokio = { workspace = true, features = ["rt-multi-thread", "macros", "time", "sync"] } vector-term = { path = "../vector-term", version = "2026.5.10" } diff --git a/crates/vector-mux/src/cwd.rs b/crates/vector-mux/src/cwd.rs index 376adba..ebc4417 100644 --- a/crates/vector-mux/src/cwd.rs +++ b/crates/vector-mux/src/cwd.rs @@ -1,8 +1,12 @@ +#![allow(unsafe_code)] //!

On Err, the fallback chain emits a `tracing::warn!` with the err and pid, then tries `$HOME`, then `/`. 5 unit tests cover the chain (returns home on pid None, returns / on home unset, returns / on home empty, pid 0 falls back to home, pidcwd self matches current_dir). +- **`proc_tracker.rs`** — `proc_name_poll_loop` runs forever at 1Hz (`MissedTickBehavior::Skip` — RENDER-03), walks `Mux::get().panes_snapshot()`, calls `unsafe { libc::tcgetpgrp(master_fd) }` for each pane, resolves via `libproc::proc_pid::pidpath`, takes the file_name basename, and invokes the callback only on transitions (`last_seen: HashMap` diff). `spawn_proc_tracker(emit)` wraps in `tokio::spawn` and returns the JoinHandle. +- **`Mux::create_tab_async(window_id, cwd, rows, cols) -> Result<(TabId, PaneId)>`** calls `default_domain.spawn_local(...)`, constructs a fresh `Arc>` and `Pane` from the returned `SpawnedPane`, then `install_tab`. The `.await` precedes any RwLock write — Pitfall B compliance. +- **`Mux::split_pane_async(pane_id, dir, cwd) -> Result`** looks up the parent pane's shell_pid + the tab's last (rows, cols), resolves cwd via `inherit_cwd(parent_pid)` if caller passed None, spawns, then `split_pane`. +- **`Mux::resize_window(window_id, rows, cols) -> Vec<(PaneId, rows, cols)>`** walks each tab, updates `Tab.last_rows/cols`, calls `split_tree::redistribute(&mut tab.root, viewport)`, then iterates `compute_layout` to produce per-pane (rows, cols). The App layer relays each tuple through `PtyActorRouter::send_resize` — kernel SIGWINCH reaches child shells via the existing `PtyTransport::resize` (CORE-04 reuse from Phase 2). +- **`Pane::shell_pid()` + `Pane::master_fd()`** — read accessors for the `pid` + `master_fd` fields (cheap, no lock). + +### vector-app + +- **`pty_actor.rs` (REWRITE)** — `PtyActorRouter { proxy, lpm_flag, pane_writers: HashMap>>, pane_resizers: HashMap>, coalesce_buffers: HashMap>, join_set: JoinSet }`. `spawn_pane(pane_id, transport)` wires three channels, spawns the per-pane `frame_tick_loop`, spawns the per-pane `pane_io_loop` into the JoinSet. `send_write` / `send_resize` do `try_send` (non-blocking); `join_next_exited` awaits the next pane's exit and returns its PaneId; `shutdown_pane` drops a pane's channels (so the actor's select! observes channel close and the loop breaks). 2 unit tests cover the JoinSet + take_reader-twice semantics. +- **`pane_io_loop`** — private per-pane task body. Biased `tokio::select!` over `resize_rx > write_rx > reader.recv()` matches Plan 02-05's single-pane shape. On transport.wait() completion, emits `UserEvent::PaneExited(pane_id)` and returns `pane_id` from the task body so `JoinSet::join_next` surfaces it. +- **`frame_tick.rs`** — `frame_tick_loop(pane_id, coalesce, proxy, lpm)` signature change. Emit becomes `UserEvent::PaneOutput { pane_id, bytes }` instead of `UserEvent::PtyOutput(bytes)`. +- **`main.rs` UserEvent migration** — `PtyOutput(Vec)` → `PaneOutput { pane_id, bytes }`; `Resized { rows, cols }` → `PaneResized { pane_id, rows, cols }`; added `PaneExited(PaneId)` + `PaneTitleChanged { pane_id, label }`. `LpmChanged(bool)` unchanged. Bootstrap creates `LocalDomain::new()` + `Mux::new() + Mux::install`, then `create_tab_async(window_id, None, 24, 80)`, then `PtyActorRouter::spawn_pane`. `spawn_proc_tracker` spawned with a closure that bridges (PaneId, String) → `EventLoopProxy::send_event(PaneTitleChanged)`. +- **`app.rs` user_event arms** — Phase-3 single-Term + single-Compositor pipeline preserved as a shim (`let _ = pane_id;`). `PaneExited` + `PaneTitleChanged` logged via `tracing::info!`; Plan 04-04 will wire them to sentinel-line rendering + tab title updates. + +### Tests + +- **`cwd_fallback.rs` (un-ignored, unit)** — 4 tests: home-when-pid-none, slash-when-pid-none-and-home-unset, slash-when-home-empty, pid-zero-falls-back-to-home. +- **`cwd_inheritance.rs` (real-PTY integration)** — spawn shell with cwd=/tmp, sleep 300ms, call `vector_mux::cwd::pidcwd(p1_pid)` → assert `/tmp` or `/private/tmp` (macOS symlink). Split, sleep 300ms, call pidcwd on p2 → assert same. Wall-clock ~0.6s. +- **`proc_name_tracking.rs` (real-PTY integration)** — spawn shell, drain banner, assert initial fg name in `[sh, zsh, bash, dash]`. Write `exec sleep 30\n`. Poll `tcgetpgrp + libproc::pidpath` every 200ms for up to 3s. Assert `"sleep"` observed. Wall-clock ~0.6s. +- **`pane_resize_propagates.rs` (real-PTY integration)** — Phase 1: bare `LocalDomain::spawn_local` round-trip — write `tput cols\n`, parse, assert ~80; resize 80→160 via `transport.resize`, assert tput sees ~160. Phase 2: Mux split — `create_tab_async` + `split_pane_async`, `resize_window(80)` redistributes 80 → 40/39, `tput cols` in each pane reports its share; sum is 79 (80 minus divider). Wall-clock ~3.3s. + +## libproc::pidcwd macOS Gap (Deviation Rule 1 — Bug) + +**Found during:** Task 2, first run of `cwd_inheritance` test. + +**Issue:** `libproc 0.14.11`'s `proc_pid::pidcwd(pid)` is documented as `Err("pidcwd is not implemented for macos".into())` — the function exists but always errors on macOS. The Plan's `` block and the upstream pidpath docs implied it worked. Plan 04-01's research and SUMMARY hand-off both assumed `libproc::pidcwd` would deliver the cwd. + +**Fix:** Implemented `vector_mux::cwd::pidcwd(pid) -> Result` directly: +- `cfg(target_os = "macos")`: call `libc::proc_pidinfo(pid, libc::PROC_PIDVNODEPATHINFO, 0, &mut info, size)`, parse `proc_vnodepathinfo.pvi_cdir.vip_path` (a NUL-terminated `[c_char; MAXPATHLEN]` represented in libc as `[[c_char; 32]; 32]` for older rustc). +- `cfg(not(target_os = "macos"))`: delegate to `libproc::proc_pid::pidcwd` (works on Linux via `/proc//cwd` readlink). + +`inherit_cwd_with` now calls `pidcwd(pid)` instead of `libproc::proc_pid::pidcwd(pid)`. The fallback chain on Err is unchanged. Added a sanity unit test `pidcwd_of_self_matches_current_dir` that exercises the shim without a real PTY. + +**Files modified:** `crates/vector-mux/src/cwd.rs`, `crates/vector-mux/tests/cwd_inheritance.rs`. + +**Committed in:** `a47670e`. + +**Impact:** Substantive deviation. Plan 04-04 (which uses inherit_cwd via Mux::split_pane_async) and Plan 04-05 (smoke matrix #4: Cmd-D in `~/personal/vector` -> new pane prompts in `~/personal/vector`) are unaffected at the API boundary — they call `vector_mux::cwd::inherit_cwd` which routes through the shim transparently. Plan 04-01's docs that said "libproc::pidcwd happy path" should be re-read as "vector_mux::cwd::pidcwd happy path" going forward. + +## Other Deviations + +### Auto-fixed (Rule 1) + +**1. [Rule 1 - Format] rustfmt rewraps `tracing::warn!` macro args + closure body** +- Found during Task 1 fmt check. rustfmt prefers multi-line `tracing::warn!` for >100ch and prefers `.and_then(|x| call(x))` over a wrapped block. +- Fixed via `cargo fmt --all`. + +**2.

The router carries `lpm_flag` so the per-pane frame_tick respects D-46. +- **App.rs single-pane shim** — `let _ = pane_id;` arms must be replaced with PaneId-keyed routing across the Mux: look up the target `Pane`, lock its `Arc>`, feed bytes there. `PaneExited` should mark the pane as exited (Plan 04-02 already provides the `exited: AtomicBool` field); on close cascade, route via `mux.close_pane(pane_id) -> CloseResult` and react in the App (drop winit Window on `WindowClosed`, exit loop on `LastWindowClosed`). `PaneTitleChanged` should propagate to the NSWindow title (the `D-56` NSWindowTabbingMode-managed window will reflect it in the system tab bar). +- **`vector_mux::cwd::inherit_cwd(parent_pid)`** is the canonical cwd resolver. When users hit Cmd-D in `~/personal/vector`, Plan 04-04's split handler must call `mux.split_pane_async(active_pane, dir, None)` — passing None invokes `inherit_cwd(parent.shell_pid())` internally, which our macOS shim resolves via `proc_pidinfo`. +- **D-38 invariant** — `crates/vector-mux/src/domain.rs` + `transport.rs` are byte-identical to Phase 2 Plan 02-04.

App layer dispatches Mux variants to the mux command handler and never reaches PTY. - 14 new keymap entries recognized BEFORE the xterm key table (D-59/D-60/D-61/D-62): Cmd-T/D/W, Cmd-Shift-D/]/[, Cmd-Opt-Arrow ×4, Cmd-Shift-Arrow ×4. Accept both shifted+unshifted character glyphs. - vector-input depends on vector-mux for the Direction enum (no cycle — vector-mux has no vector-input dep). - 14 xterm_key_table Wave-0 stubs un-ignored and assert real MuxCommand variants. All 86 existing tests wrap byte-vec assertions in EncodedKey::Pty(...). 100/0/0 in vector-input; workspace 226/0/5. - vector-app keyboard handler updated minimally (matches EncodedKey; logs Mux variants as a stub — Task 2 wires the dispatcher).

charset=UTF-8 Content-Transfer-Encoding: 8bit - Compositor gains window_size_px / viewport_offset_px / viewport_size_px so one wgpu surface can host N panes (per-pane sub-region NDC). Single-pane callers see offset=(0,0) and viewport=window — no behavior change. - New API: set_viewport, set_border_color, set_cursor_focused, new_with_viewport, render_into_view(LoadOp). Multi-pane frames clear once via the first pane's LoadOp::Clear and chain LoadOp::Load through the rest. - cell.wgsl Uniforms extended: border_color, viewport_offset_px, viewport_size_px, border_width_px (D-66). Fragment shader paints pixels within border_width_px of any viewport edge when border_color.a > 0. - cursor.wgsl Uniforms extended: window_size_px, viewport_offset_px, cursor_focused. Focused=filled rect; unfocused=1-px stroke outline (only edge pixels render; interior is transparent). Cursor blend switched to ALPHA_BLENDING so transparent pixels composite over the cell pass. - Byte-exact Rust↔WGSL uniform layout for both pipelines (cell=80B, cursor=64B; explicit pad fields keep vec4 fields 16-aligned). - active_pane_border test un-ignored: 2 cases assert top-edge pixels are red when border_color=[1,0,0,1] and zero red pixels when alpha=0. Workspace: 228 passed / 0 failed / 4 ignored (was 226/0/5).

Integration tests can drive the modules without a real winit loop. - App refactored from a single Window to HashMap (D-56). Each AppWindow owns its RenderHost / overlay / first-paint gate / resize-debounce state. Cmd-T spawns a new tab-grouped winit Window. - New `mux_commands` module: WindowFactory trait + WinitWindowFactory. Production calls winit's WindowExtMacOS::set_tabbing_identifier *and* objc2-app-kit setTabbingMode(.preferred) as a belt-and-braces mitigation for winit#2238. VECTOR_TABBING_IDENTIFIER = "com.vector.terminal". - handle_mux_command dispatches all 8 MuxCommand variants: NewTab → spawn tab-grouped window ClosePane → mux.close_pane cascade; LastWindowClosed exits the loop CycleTabNext/Prev → mux.cycle_tab on every registered window_id SplitH/V, FocusDir, NudgeSplit → mux state mutation + log (Plan 04-05 wires the per-pane Compositor + redistribute side-effects). - Mux gains `try_get()`, `any_active_pane_id()`, `window_ids_snapshot()` helpers — needed by App to probe singleton state without panicking. - Menu: File→New Tab is now enabled (key-equivalent only — no AppKit action, so the keystroke flows through winit to the keymap → MuxCommand::NewTab). File→Close (Cmd-W) keeps its existing performClose: wiring. - TabWindow struct seeded in tab_window.rs for Plan 04-05's per-pane Compositor map; Plan 04-04 ships the seam, polish lands next. - WindowEvent::CloseRequested now removes the closed window from the map and exits the event loop when no windows remain. - multi_window_tabbing test un-ignored: a recording WindowFactory mock asserts every Cmd-T invocation passes "com.vector.terminal" through. D-38 invariant: zero hunks in vector-mux/src/{domain,transport}.rs. WIN-04 arch-lint: vector_term_does_not_discriminate_on_transport_kind green. Arch-lint count: 16. Workspace tests: 231 passed / 0 failed / 3 ignored.

The seeded design from Plan 04-04 was: iterate compositors in z-order with `LoadOp::Clear(...)` on the first and `LoadOp::Load` on subsequent, single `frame.present()` outside the loop. Wiring this is Plan 04-06's Task 1. + +**Gap 2 — Per-pane viewport math is not driving SIGWINCH.** `Mux::resize_window` returns `Vec<(PaneId, u16, u16)>`; `TabWindow::flush_pending_resize_if_quiescent` consumes the layout vec but the per-pane `router.send_resize(pane_id, rows, cols)` walks the vec with the wrong indices — every pane ends up receiving the window-total (rows, cols) rather than its layout-computed slice. This is why `tput cols` is identical in both panes. Plan 04-06's Task 2 / Task 3. + +**Gap 3 — Visible D-66 border.** Border shader + uniform exist; `set_border_color([0.4, 0.6, 1.0, 1.0])` is called from `handle_mux_command(FocusDir)`, but the per-pane render loop never reaches that compositor with the right `LoadOp` to expose the border. Lands automatically once Gap 1 closes. Plan 04-06's Task 1. + +**Why this is honest:** WIN-03's acceptance criteria explicitly include "running an independent shell in each pane" + "tput cols reports correct width" + "focus routing visible". The data-layer green-bar (unit tests for split tree, directional focus, nudge-ratio, close cascade all PASS) does not satisfy the visible-render requirement. WIN-03 stays Pending in REQUIREMENTS.md until Plan 04-06 closes Gaps 1–3. + +## Decisions Made + +- **Task 1 ships the architecturally-seeded design; Task 2's FAILs are routed to Plan 04-06 instead of inline-fixing.** Wiring the per-pane render loop is a discrete, well-scoped piece of work (one Compositor iteration + one viewport-vec indexing fix + verification that the existing D-66 border setter reaches pixels). It does not belong in a "polish + smoke" plan; it deserves its own gap-closure plan with explicit acceptance criteria tied to items #3/#4/#8. +- **WIN-02 lands** (Cmd-T + Cmd-W cascade both PASS). **WIN-03 does NOT land** (visible side-by-side render + per-pane viewport math remain unmet). **WIN-04 was already landed by Plan 04-02** (grep arch-lint live). +- **Decisions honored partially:** D-51 PASS (per-window gate works); D-56 PASS (#1); D-57 PASS (#7); D-59 = data-layer PASS via 04-02 unit tests, visible FAIL = #3 (defer to 04-06); D-61 PASS (#2); D-63 PASS (#5); D-66 = shader exists but not reaching pixels, FAIL = #8 (defer to 04-06); D-67 PASS (data-layer split tree fully tested via 04-02). + +## Deviations from Plan + +None for Task 1 — the audit invariants (per-TabWindow first_paint_ready, focus-change side-effects, per-window resize debounce, final clippy/fmt/arch-lint sweep) were all hit on the first pass. The deviation from the Plan-05 success criteria is the smoke matrix verdict, not the implementation: Plan 04-05 expected the 9-item matrix to PASS and close Phase 4; instead it returned 3 documented FAILs that route to a gap-closure plan. This is the expected `gaps_found` outcome the verifier will surface next. + +## Issues Encountered + +- The 9-item smoke matrix surfaced the three visible-render gaps (#3, #4, #8) which are documented in Plan 04-06's scope.

We extend `AppWindow` in place rather than swap to `TabWindow` to minimize churn — the TabWindow type stays (it is `pub use`-d in lib.rs and tested via multi_window_tabbing.rs) but remains a parallel data structure consumed only by the test factory pattern. + + **Step 1 — Plumb router + mux-window-id map into App (preconditions for Gaps 1, 2):** + + 1a. In `crates/vector-app/src/app.rs:42-54`, extend `pub struct App` with: + - `router: Option>>` — set via a new `set_router()` method analogous to `set_split_req_tx()`. + - `winit_to_mux_window: HashMap` — initialized empty in `App::new()`. + + 1b. Add `pub fn set_router(&mut self, router: Arc>) { self.router = Some(router); }` near `set_split_req_tx` (line 75-77). + + 1c. In `crates/vector-app/src/main.rs:80-81`, after `let router = Arc::new(parking_lot::Mutex::new(router));`, add `let router_app = Arc::clone(&router);` and after `application.set_split_req_tx(split_req_tx);` (line 136) add `application.set_router(router_app);`. + + 1d. In `app.rs::resumed` (around line 277, where the bootstrap AppWindow is inserted) and in `app.rs::handle_new_tab` (around line 146, where additional tab windows are inserted), record the `winit_to_mux_window` entry. The bootstrap pane's mux WindowId is reachable via `Mux::try_get().and_then(|m| m.window_ids_snapshot().first().copied())`. + + **Note (Plan 04-06 bounded scope):** the live `handle_new_tab` records a tab-grouped winit window but does NOT spawn a Mux Tab+Pane (per 04-04-SUMMARY.md "Hand-off to Plan 04-05"). For Plan 04-06, ONLY the bootstrap window's mapping needs to be correct. Subsequent Cmd-T windows can share the bootstrap mux WindowId for now (smoke item #1 already passes against the existing behavior — the user's smoke verdict 2026-05-12 had #1 PASS). Add a TODO comment: `// TODO(phase-5): per-NSWindow mux WindowId allocation when Cmd-T spawns a fresh Mux Tab+Pane.` + + **Step 2 — Extend AppWindow with per-pane Compositor map (Gap 1):** + + 2a. In `crates/vector-app/src/app.rs:32-40`, modify `struct AppWindow` to add: + ```rust + compositors: std::collections::HashMap, + active_pane_id: Option, + ``` + Keep all existing fields (`window`, `render_host`, `overlay`, `overlay_dropped`, `first_paint_ready`, `last_resize_at`, `pending_resize`). The `compositors` map is populated lazily — when `UserEvent::PaneOutput` arrives for a `pane_id` not yet in the map, lazily create a `Compositor` via `Compositor::new_with_viewport(...)` using the layout-derived viewport rect (see Step 4). The existing `render_host` stays for clear-color fallback only. + + 2b. Initialize the two new fields to `HashMap::new()` and `None` in both `AppWindow` constructions (around line 146 in `handle_new_tab` and line 277 in `resumed`). + + **Step 3 — Rewrite RedrawRequested to iterate compositors (Gap 1 + Gap 3 visible):** + + 3a. Replace `app.rs:485-507` (`WindowEvent::RedrawRequested` arm) with the per-pane render loop: + - Check `first_paint_ready` gate (preserve existing behavior). + - Call `self.flush_pending_resize_if_quiescent(id)` (preserve). + - To acquire the surface texture once and orchestrate `LoadOp::Clear` then `LoadOp::Load`, expose what is needed from `RenderHost`. Add a method `RenderHost::with_frame(&mut self, f: F) -> anyhow::Result<()>` where `F: FnOnce(&wgpu::Device, &wgpu::Queue, &wgpu::TextureView, u32 /* surface width */, u32 /* surface height */) -> anyhow::Result<()>`. The implementation acquires the surface texture, creates the view, calls `f`, then calls `frame.present()`. This is the smallest change to RenderHost's API and keeps surface-lifetime borrow rules clean. + - Inside the closure: derive per-pane viewport rects from the current Mux Tab. Compute `cols = window_width_px / cell_w` and `rows = window_height_px / cell_h` using the first compositor's `cell_width_px()` / `cell_height_px()` (all compositors share the same font/cell metrics). Call `mux.with_tab(window_id, tab_id, |tab| compute_layout(&tab.root, Rect { x: 0, y: 0, w: cols, h: rows }))`. Convert each cell-rect `Rect` to a pixel viewport via `offset_px = (rect.x * cell_w, rect.y * cell_h)` and `size_px = (rect.w * cell_w, rect.h * cell_h)`. + - For each `(pane_id, rect)` in the layout (sort by PaneId for determinism), look up the pane's Term. Plan 04-03 placed the per-pane Term on `Mux::Pane`; the read accessor is the `parking_lot::Mutex` lock on the pane (see `crates/vector-mux/src/pane.rs` — confirm the field/accessor name during execution). If a per-pane Term accessor is not present, the minimal-viable Plan-04-06 closure is: feed bytes into `self.term` ONLY for the active pane, render each non-active pane against a small shared `Term::new(...)` initialized to its viewport dims and seeded with whatever shell prompt is reachable. **Preferred path:** the per-pane Term is the source of truth; pursue this first. + - For each pane's compositor: + - Call `compositor.set_viewport(queue, [offset_x_px, offset_y_px], [size_w_px, size_h_px])`. + - Call `compositor.set_border_color(queue, if Some(pane_id) == aw.active_pane_id { [0.4, 0.6, 1.0, 1.0] } else { [0.0, 0.0, 0.0, 0.0] })`. + - Call `compositor.set_cursor_focused(Some(pane_id) == aw.active_pane_id)`. + - Call `compositor.render_into_view(device, queue, view, window_width_px, window_height_px, &mut term, sel_or_none, load_op)` where `load_op = LoadOp::Clear(default_bg)` on the FIRST iteration and `LoadOp::Load` on SUBSEQUENT iterations. The selection is only forwarded to the active pane. + + 3b. If `compositors` is empty (no panes registered yet — pre-first-paint window state), fall back to the existing `host.render(&mut t, sel)` path. This preserves the bootstrap path before the first `UserEvent::PaneOutput`. + + **Step 4 — Lazy Compositor creation on first PaneOutput (Gap 1 plumbing):** + + 4a. In `app.rs::user_event::UserEvent::PaneOutput { pane_id, bytes }` (lines 293-328), when `bytes` is non-empty: locate the winit_window_id holding this pane (Plan 04-06: bootstrap window — all panes share it). For that AppWindow: + - If `compositors.get(&pane_id).is_none()`: lazily construct via `Compositor::new_with_viewport(...)` using a viewport derived from the current Mux layout. If creation fails, log via tracing and continue (do not panic). + - If `active_pane_id.is_none()`, set it to the first pane registered (the bootstrap pane); subsequent panes do NOT auto-flip focus (the user changes focus only via Cmd-Opt-Arrow per D-59). + - Feed the bytes into the per-pane Term via the pane's mutex lock. For backward compat with selection / cell_from_pixel which currently use `self.term`, keep mirroring the ACTIVE pane's bytes into `self.term` so the existing selection + cursor coords plumbing keeps working. Plan 05 will move selection to per-pane. + + **Step 5 — Per-pane viewport math drives SIGWINCH (Gap 2):** + + 5a. Replace the body of `app.rs:107-119` (`fn flush_pending_resize_if_quiescent`) with the per-pane walk: + ```rust + fn flush_pending_resize_if_quiescent(&mut self, id: WindowId) { + let Some(aw) = self.windows.get_mut(&id) else { return }; + let (Some(at), Some((rows, cols))) = (aw.last_resize_at, aw.pending_resize) else { return }; + if at.elapsed() < RESIZE_DEBOUNCE { return } + let Some(mux) = Mux::try_get() else { return }; + let Some(mux_window_id) = self.winit_to_mux_window.get(&id).copied() else { return }; + let Some(router) = self.router.as_ref().cloned() else { return }; + for (pane_id, prows, pcols) in mux.resize_window(mux_window_id, rows, cols) { + router.lock().send_resize(pane_id, prows, pcols); + } + aw.pending_resize = None; + aw.last_resize_at = None; + } + ``` + This mirrors `tab_window.rs:72-90` (the orphaned correct-shape helper). The single-channel `self.input_bridge.send_resize(rows, cols)` call disappears. + + **Step 6 — Visible D-66 border at focus change (Gap 3):** + + 6a. In `app.rs:220-235` (`MuxCommand::FocusDir` handler), after the existing `mux.focus_direction` succeeds: + - Get the AppWindow holding the focused pane (Plan 04-06: bootstrap window). + - Look up the wgpu `Queue` via the AppWindow's `render_host`. Add a `RenderHost::queue(&self) -> Option<&wgpu::Queue>` getter that returns `Some(&self.ctx.queue)` (the underlying `RenderContext` already holds the queue). + - On the new-active pane's compositor: `compositor.set_border_color(queue, [0.4, 0.6, 1.0, 1.0])` and `compositor.set_cursor_focused(true)`. + - On the old-active pane's compositor: `compositor.set_border_color(queue, [0.0, 0.0, 0.0, 0.0])` and `compositor.set_cursor_focused(false)`. + - Update `aw.active_pane_id = Some(new_id)`. + - Call `self.request_redraw_all()` (preserved). + + **Step 7 — Hygiene + final sweep:** + + - Run `cargo fmt --all`. + - Run `cargo clippy --workspace --all-targets -- -D warnings`. Auto-fix per project Rule 1 (project clippy::pedantic posture). Pay attention to: `too_many_lines` on `window_event` (the RedrawRequested arm gets bigger — extract a `fn render_panes_for_window(...)` helper if it exceeds the threshold; the existing `#[allow(clippy::too_many_lines)]` may carry the cost); `clippy::missing_panics_doc` on the new `RenderHost::with_frame` helper (add `# Panics` doc if any `expect` is on the surface acquisition path); `clippy::cast_possible_truncation` on the viewport pixel math (use the existing `#[allow]` annotations from the surrounding code). + - Verify D-38 invariant: `git diff HEAD -- crates/vector-mux/src/domain.rs crates/vector-mux/src/transport.rs` returns ZERO hunks. + - Verify WIN-04 arch-lint still live: `cargo test -p vector-term --test no_transport_discrimination` passes (2 tests). + - Verify arch-lint count: `find crates -name 'no_tokio_main.rs' -o -name 'no_transport_discrimination.rs' | wc -l` returns 16. + - Workspace test gate: `cargo test --workspace --tests -q` returns at least 231 passed / 0 failed (Plan 04-05 baseline). Existing tests must not regress. + + **Commit:** one commit covering Steps 1-7 with message `fix(04-06): wire per-pane Compositor render loop + per-pane SIGWINCH + visible D-66 border (closes Gap 1/2/3 from 04-VERIFICATION.md)`. + + **Notes for the executor (per 04-CONTEXT.md):** + - D-09/D-10/D-11 invariants hold: winit `EventLoop` on main, tokio on background, `EventLoopProxy::send_event` is the only cross-thread signal, `parking_lot::Mutex` never held across `.await`. The new code is on the main thread (App is in winit callback) so locking via `Arc>::lock()` is fine — no await inside the critical section. + - Pitfall 21 scope guard: NO layout save/restore, NO broadcast-input, NO zoom toggle, NO new modal modes.

Gap 1 (smoke #3 — visible side-by-side multi-pane render): - AppWindow gains `compositors: HashMap` + `active_pane_id`. - New `App::render_window` acquires the surface frame once, then iterates the active tab's leaves (sorted by PaneId for determinism), calling `Compositor::render_into_view` per pane with chained LoadOp::Clear (first) + LoadOp::Load (subsequent) so every pane paints onto the same view. - Layout derived from `vector_mux::compute_layout(&tab.root, viewport)`; per-pane viewport offset_px + size_px computed from cell metrics. - `ensure_compositors_for_pane` lazily builds per-pane Compositors via `RenderHost::new_compositor_for_viewport`. Gap 2 (smoke #4 — per-pane `tput cols`): - `flush_pending_resize_if_quiescent` rewritten to walk `Mux::resize_window(window_id, rows, cols)` and route each `(pane_id, rows, cols)` through `PtyActorRouter::send_resize`, so kernel SIGWINCH reaches each child shell with its own viewport dims. - Single-channel `self.input_bridge.send_resize` call removed from the resize path. The legacy resize_rx channel still exists in main.rs for single-pane fallback per Plan 04-05. - New `App.winit_to_mux_window` HashMap records the bootstrap mapping in `resumed` + `handle_new_tab`. New `App.router: Option>>` set by `set_router` from main.rs. Gap 3 (smoke #8 — visible D-66 active-pane border): - `MuxCommand::FocusDir` handler invokes `apply_focus_change(new_id)`: `set_border_color([0.4, 0.6, 1.0, 1.0])` on new-active compositor + `set_border_color([0.0, 0.0, 0.0, 0.0])` on old-active; flips `set_cursor_focused` to filled vs hollow. - Border-color is also reapplied each frame inside `render_window` based on `aw.active_pane_id` so the accent stays consistent across redraws. Supporting plumbing: - `RenderHost` grows `queue()`, `device()`, `surface_format()`, `surface_size()`, `acquire_frame() -> Option`, and `new_compositor_for_viewport(offset_px, size_px)`. `AcquiredFrame` exposes view + width + height + `present()`. - main.rs constructs PtyActorRouter on the main thread (instead of inside the I/O thread) so `Arc>` can be shared with the App for SIGWINCH fanout. I/O thread still drives `spawn_pane` for the bootstrap pane + Cmd-D split panes; main-thread App owns the resize fanout. D-09/D-10/D-11 invariants preserved. - `UserEvent::PaneOutput` now feeds bytes into the pane's own per-pane Term (Mux::Pane.term mutex), mirroring active pane's bytes into the App's shared `self.term` for backward-compat selection / cell_from_pixel. Every PaneOutput triggers `request_redraw` (not just the active one) so background pane output paints immediately. Invariants held: - D-38 (vector-mux/src/{domain,transport}.rs zero hunks) — verified - WIN-04 arch-lint live — `vector-term --test no_transport_discrimination` 2/2 PASS - arch-lint file count — 16 - Workspace tests — 231 passed / 0 failed / 3 ignored (baseline) - clippy --workspace --all-targets -D warnings — clean - fmt --check — clean Pitfall 21 scope guard observed: no layout save/restore, no broadcast input, no zoom toggle, no new modal modes. Pure render-loop wiring + per-pane SIGWINCH walk + border-color invocation.

Compositor stays orthogonal — no first-paint state on its side. **Scroll-wheel scrollback**: `Term::scroll_display(delta)` + `Term::scrollback_offset()` on the vector-term wrapper (delegates to `alacritty_terminal::Term::scroll_display(Scroll::Delta(_))`); both `LineDelta` + `PixelDelta` arms in app.rs wired (Plan 03-04's deferred `tracing::debug!` stubs deleted).

Per-kind ID counters (next_pane / next_tab / next_window in `IdAllocator`) replace Plan 04-01's single shared counter so tests can assert `PaneId(1)` for the first allocation.

User-approved 9/9 smoke matrix re-run on 2026-05-12: items #3 (visible side-by-side multi-pane render), #4 (per-pane `tput cols`), #8 (visible D-66 active-pane border) all flipped FAIL -> PASS; items #1, #2, #5, #6, #7, #9 stayed PASS with no regression.

Workspace test gate clean: 231/0/3 default; 234/0/0 with --include-ignored; clippy + fmt clean; arch-lint count 16; D-38 invariant byte-identical.

The three documented-stub comments flagged in the prior verification (`app.rs:293-328` shim, `app.rs:220-235` border-flip deferral, `app.rs:180-204` Plan 04-06 handoff comment) are resolved — the FocusDir handler now invokes `set_border_color` + `set_cursor_focused` on the per-pane compositor map (`crates/vector-app/src/app.rs:193-200, 199-200, 307-315`), the per-pane render loop iterates compositors (`crates/vector-app/src/app.rs:319-347`), and the per-pane Term mirroring is documented as the intentional shape (Plan 04-06 key-decision: "Per-pane Term writes are the source of truth for the render loop"; selection movement to per-pane is explicitly deferred to Phase 5). + | File | Line | Pattern | Severity | Impact | | ---- | ---- | ------- | -------- | ------ | -| `crates/vector-app/src/app.rs` | 293-328 | Shim comment: "only the currently-active Mux pane is mirrored into the visible Term" | ℹ️ Info | Documented intentional scope boundary — not a hidden stub. | -| `crates/vector-app/src/app.rs` | 220-235 | Shim comment: "Multi-pane border flip + cursor_focused toggle lands when the per-pane Compositor map goes live" | ℹ️ Info | Documented intentional scope boundary. | -| `crates/vector-app/src/app.rs` | 180-204 | Comment: "Per-pane Compositor wiring + visible second-shell rendering lands in the multi-pane render polish (Plan 04-06 gap-closure)" | ℹ️ Info | Explicit Plan 04-06 handoff annotation. | -| `crates/vector-app/src/tab_window.rs` | 23-37 | Defined `TabWindow` with `compositors` map is `pub use`-exported but never instantiated in the live `App::resumed` / Cmd-T path | ⚠️ Warning (orphan) | The seam is real, the type is in tree; just unused at runtime.

See `human_verification` block in frontmatter. +The 9-item smoke matrix is by-design human-verified (visual contrast judgment, AppKit tab-group behavior, real-PTY SIGWINCH timing, DPR change between physical monitors). The user re-walked all 9 items on 2026-05-12 and approved the matrix (9/9 PASS, 0 FAIL). No re-walk is required for this verifier round — human verification is satisfied; sign-off recorded in `04-06-SUMMARY.md`. + +## Closure Summary -## Gaps Summary +Plan 04-06 closed the three FAILs from the prior verification with one architectural fix (commit `f6f7d25`): `AppWindow` was extended in place with `compositors: HashMap` + `active_pane_id: Option`. The same migration unlocked all three gaps simultaneously: -The user-verdict (6 PASS / 3 FAIL on the 9-item smoke matrix) is honest and matches the codebase exactly. Three failed smoke items collapse to one shared root cause and one architectural gap: +1. **Gap 1 (smoke #3 — visible side-by-side render):** `RedrawRequested` now derives per-pane viewport rects from `vector_mux::compute_layout`, iterates compositors sorted by PaneId for determinism, calls `Compositor::render_into_view` with chained `LoadOp::Clear` (first leaf) + `LoadOp::Load` (subsequent), and presents once outside the loop. +2. **Gap 2 (smoke #4 — per-pane `tput cols`):** `flush_pending_resize_if_quiescent` now walks `Mux::resize_window(mux_window_id, rows, cols)` → `Vec<(PaneId, prows, pcols)>` → `PtyActorRouter::send_resize(pane_id, prows, pcols)` per layout entry. +3. **Gap 3 (smoke #8 — visible D-66 active-pane border):** `MuxCommand::FocusDir` handler invokes `comp.set_border_color(queue, [0.4, 0.6, 1.0, 1.0])` + `comp.set_cursor_focused(true)` on new-active and clears on old-active using the shared wgpu Queue surfaced via `RenderHost::queue`. -**Root cause:** The phase 4 implementation ships two parallel structs for per-window state: -1. `AppWindow` (in `app.rs:32`) — the live struct used at runtime, single-pane shaped. -2. `TabWindow` (in `tab_window.rs:23`) — the multi-pane-correct struct with `compositors: HashMap` + a correctly-shaped `flush_pending_resize_if_quiescent` helper, but never instantiated. +Support extensions: `RenderHost::with_frame` surface-frame closure; `RenderHost::new_compositor_for_viewport` lazy per-pane Compositor factory; `RenderHost::queue` shared-queue accessor; `PtyActorRouter` lifted to `Arc>` so `App::set_router` reaches the main-thread render+resize site (`main.rs`); `winit_to_mux_window` map records bootstrap mapping. -**Architectural gap:** The render loop (`app.rs:485-507`) iterates the single `AppWindow.render_host`; it never reaches a per-pane compositor map. Per-pane viewport-derived SIGWINCH (`app.rs:107-119`) never reaches `Mux::resize_window`. The active-pane border setter is never invoked at the focus-change site (`app.rs:220-235`). +All automated verification gates held across the migration: workspace tests 231/0/3 (baseline preserved); clippy clean with `-D warnings`; rustfmt clean; WIN-04 arch-lint live (2/2); D-66 snapshots live (2/2); arch-lint file count = 16; D-38 zero-diff invariant confirmed (`git diff -- crates/vector-mux/src/domain.rs crates/vector-mux/src/transport.rs` returns zero hunks). -**Plan 04-06 scope (handoff for `/gsd:plan-phase 4 --gaps`):** +## Cross-Phase / Deferred Notes -- **Task 1 — Per-pane Compositor render loop** (closes Gap 1 + Gap 3 simultaneously) - - File: `crates/vector-app/src/app.rs:32-40` (AppWindow struct), `crates/vector-app/src/app.rs:485-507` (RedrawRequested), `crates/vector-app/src/app.rs:220-235` (FocusDir handler). - - Either swap `AppWindow` → `TabWindow` or extend `AppWindow` with `compositors: HashMap` + `active_pane_id: PaneId`. - - Iterate compositors in `RedrawRequested` with `LoadOp::Clear` first / `LoadOp::Load` subsequent. Use the existing `Compositor::render_into_view(LoadOp)` API. - - In `MuxCommand::FocusDir`: call `set_border_color([0.4, 0.6, 1.0, 1.0])` on the new active compositor and clear it on the old. The D-66 border will then reach pixels automatically. -- **Task 2 — Per-pane viewport math drives SIGWINCH** (closes Gap 2) - - File: `crates/vector-app/src/app.rs:107-119`. - - Replace `self.input_bridge.send_resize(rows, cols)` with the per-pane walk shape already implemented in `tab_window.rs:72-90`: `for (pane_id, rows, cols) in mux.resize_window(window_id, rows, cols) { router.send_resize(pane_id, rows, cols); }`. - - Requires plumbing `Mux` (via `Mux::try_get()`) and `PtyActorRouter` reference into the App for the flush call site, plus a `winit::WindowId` → `vector_mux::WindowId` mapping. -- **Task 3 — Route per-pane PaneOutput to per-pane Term** - - File: `crates/vector-app/src/app.rs:293-328`. - - Instead of mirroring only the active pane into the single shared `App.term`, feed each pane's output into its own `Mux::Pane.term` (already exists as `Arc>`), and dirty-flag only that pane's compositor. -- **Acceptance:** Re-walk smoke items #3, #4, #8 — all PASS. +- **Phase 5 hand-off (Plan 04-06 key-decision):** `winit_to_mux_window` records only the bootstrap entry. Phase 5 (or whichever phase first spawns a fresh Mux Tab+Pane per NSWindow) should extend `handle_new_tab` to allocate a new `vector_mux::WindowId` and record the mapping. TODO comment placed inline. +- **Phase 5 hand-off (Plan 04-06 key-decision):** Per-pane Term writes are the source of truth for the render loop, but the active pane's bytes are mirrored into `self.term` so existing selection + `cell_from_pixel` coords plumbing keeps working. Plan 05 may move selection to per-pane. +- **`tab_window.rs` retained:** Plan 04-06 chose to extend `AppWindow` in place rather than swap to `TabWindow`. `TabWindow` remains `pub use`-exported and consumed by `multi_window_tabbing.rs` as a parallel data structure — intentional dual-data-structure choice documented in 04-06-SUMMARY.md key-decisions; not an orphan. -**WIN-03 disposition:** Stays **Pending** in REQUIREMENTS.md until Plan 04-06 closes. This is the correct disposition per Plan 04-05's finalization. Phase 4 close-out is deferred to post-04-06. +## Verdict -**Phase 4 overall:** NOT yet ready to close. 2 of 4 phase truths verified; 3 of 9 smoke items failed; WIN-03 unmet at user-visible acceptance. Plan 04-06 (gap-closure) is the bounded, well-scoped next step. +**Phase 4 is closeable.** All four phase-4 observable truths verified; WIN-02 + WIN-03 + WIN-04 all Complete in REQUIREMENTS.md; manual smoke matrix 9/9 PASS with user sign-off (2026-05-12); D-38 trait-surface invariant byte-identical to Phase 2 final shape; arch-lint count held at 16.

Matches ghostty's single-file approach. `deny_unknown_fields` per Pitfall 11. Schema validation via `serde` + a follow-up `Result` that surfaces the first error line + column. + +- **D-69:** **Live-apply theme, keybinds, font-size, ligatures-toggle, tint, and per-profile params. Font-family change and GPU-shaped keys show a `restart required` toast. On parse error: keep last-good config in memory + emit a non-blocking toast with the first error.** Debounce FSEvents at 150 ms quiescent. The toast surface is reused for D-70's clipboard prompt UI. + +### Clipboard + tmux passthrough (POLISH-05) + +- **D-70:** **OSC 52 clipboard writes are prompt-once-per-origin then remembered per-profile.** First write from a session shows a non-modal toast: `Allow [profile-name : foreground-process] to write to your clipboard? [Allow once] [Always] [Block]`. The Always/Block choice is persisted into the active `[profile.X]` block as `clipboard_write = "allow" | "block"`. Reads via OSC 52 query are *always denied* in v1 (iTerm2 default — Pitfall security row CVE-class). + +- **D-71:** **Accept both raw OSC 52 and DCS-wrapped `\eP\e]52;c;…\a\e\\` inbound. Vector never re-wraps outbound — that's tmux's job.** Payloads emitted by Vector chunk at 58 bytes to dodge the ~60-char tmux passthrough bug. README documents `set -g allow-passthrough on` and we ship a shell-integration script (Phase 6+) that sets it automatically inside a Codespace. + +### Theme strategy + `.itermcolors` (POLISH-02 / POLISH-03) + +- **D-72:** **Two bundled themes: Vector Light + Vector Dark. `[default].appearance` accepts `"system" | "light" | "dark"`, default `"system"` (follow macOS via `NSApplication.effectiveAppearance` + `NSApp` KVO).** No Solarized / Tomorrow / Gruvbox bundled — users bring those via `.itermcolors` (D-73). + +- **D-73:** **`.itermcolors` import = drop file in `~/.config/vector/themes/`, reference by stem in config.** `theme = "Solarized-Dark"` resolves to `themes/Solarized-Dark.itermcolors`. The themes dir is watched; new files become available after save, no app restart. Importer is a plist parser mapping the iTerm key set (`Ansi 0..15 Color`, `Foreground Color`, `Background Color`, `Cursor Color`, `Selection Color`, `Bold Color`) into Vector's palette struct. Unknown keys are warned + ignored. No CLI/GUI import command in v1. + +### Scrollback search UX (POLISH-06) + +- **D-76:** **Inline bottom search bar, per-pane. `Cmd-F` opens, `Esc` closes + restores prior selection.** Bar renders inside the pane's viewport (under the grid, above the divider), height ~32 px. Layout: `[/{query}/▢] [aA] [↑] [↓] [{i}/{n}] [×]` — but per D-77 the case/regex toggles are *not* visible affordances; only the query field, position counter, prev/next arrows, and close button are rendered. Built on Phase-3's compositor: search bar is its own viewport rect with a tinted background; no new pipeline. + +- **D-77:** **Smart-case + always-regex; Enter = next, Shift-Enter = prev.** Smart-case = case-insensitive when query is all-lowercase, case-sensitive when query has any uppercase (rg / vim convention). The query is *always* compiled as a regex via `vector-term::search()` D-39; non-regex chars work because they parse as literal patterns. All matches highlighted with a translucent yellow box per cell (theme-aware: yellow on dark, orange on light); active match boldened with a 1 px border. Up to 1000 matches cached; beyond that, show `1000+ matches` and step lazily. + +### Profile model + switcher UX (POLISH-07) + +- **D-74:** **`Profile { kind: Kind, name: String, … }` with `Kind = { Local, Codespace, DevTunnel }` enum and unlimited named profiles per kind.** TOML shape: + ```toml + [profile.work-cs] + kind = "codespace" + codespace_name = "octocat/hello-world-abc123" + theme = "Solarized-Dark" + tint = "#7a3aaf" + env = { FOO = "bar" } + startup_command = "tmux new -A -s vector" + ``` + Phase 5 only wires `kind = "local"` end-to-end (`SpawnCommand` via `LocalDomain`). `codespace` / `dev_tunnel` profiles parse, persist, and appear in the switcher with a `"⚠ Phase 6+"` label; connecting them no-ops with a toast. The `Profile` struct is the long-term type — Phases 6/7 fill in the transport, never reshape the schema. + +- **D-75:** **Title-bar tint stripe + minimal Cmd-Shift-P profile picker.** + - **Tint:** the per-profile `tint = "#RRGGBB"` paints a 24–32 px stripe under the NSWindow title bar (above the tab bar). Reuses an existing pipeline (researcher's call: extend the per-cell tint uniform from Phase 3 or paint via `NSVisualEffectView` overlay). Default profile has no stripe. + - **Switcher:** `Cmd-Shift-P` opens a *narrow* modal listing profile names with fuzzy match. Enter swaps the active pane's profile (re-spawns its `Domain`). No general action listing, no extensibility, no Lua surface — this is **not** a general command palette. The roadmap line "no command palette" (Phase 5 risks/notes) is honored in spirit: we are explicitly carving out profile-switching only. + - Menu fallback: `Vector → Switch Profile →` submenu mirrors the picker for users who don't know the shortcut. + +### OSC 7 / OSC 8 / OSC 133 visible behaviors (POLISH-04) + +- **D-78:** **OSC 8 hyperlinks render plain by default; mouse hover shows a dotted underline + Cmd-cursor; `Cmd-click` opens via `NSWorkspace.openURL`.** Schemes allowlisted: `https`, `http`, `mailto`, `file://`. Everything else is logged at `info` and ignored (CVE-class per Pitfalls security row — malicious log content could shellward `gopher://` etc.). URLs longer than 4096 chars are truncated + warned. Hyperlink ID (`id=`) is tracked so multi-cell ranges underline together. + +- **D-79:** **OSC 7 cwd is preferred over `proc_pidinfo` (D-63) for new-pane / new-tab cwd inheritance when present.** Each pane stores `cwd: Option`; updated whenever the shell emits `OSC 7;file://host/path/\a`. New-pane spawn uses `pane.cwd.or_else(|| proc_pidinfo_fallback(pane.pid)).unwrap_or(home)`. The tab title (D-57) gains a cwd-stem suffix when OSC 7 is present: `zsh: vector` instead of just `zsh`. **OSC 133** prompt marks (`OSC 133;A/B/C/D`) are captured into a `Vec` per pane (start, command, output, end with exit-code). UI for prompt-mark navigation (`Cmd-PageUp` jump-to-prev-prompt) is **stubbed but not wired** — the data captures now so Phase 6+ shell-integration scripts produce something useful. + +- **Claude's Discretion:** **OSC 10/11/12** fg/bg/cursor color query responses are pure VT parser responses; vim/neovim need them to detect dark mode. Implementation is mechanical — respond with the current theme colors in xterm format. + +### Secure Keyboard Entry + IME (POLISH-08) + +- **D-80:** **Secure Keyboard Entry is a single global app-state toggle, exposed only via `Vector → Secure Keyboard Entry` menu item with a checkmark.** Persisted as `[default].secure_keyboard_entry = true | false`. Implementation calls `EnableSecureEventInput()` / `DisableSecureEventInput()` on the whole process — Apple's API is process-level, not per-window, so "per-window SKE" is illusory and we don't pretend. No keyboard shortcut (`Cmd-Shift-K` is too easy to fat-finger and would surprise users). + +- **D-81:** **Basic IME = display marked text under the cursor only, no candidate window.** Implement `NSTextInputClient` `setMarkedText:selectedRange:replacementRange:` and `insertText:replacementRange:`. Preedit text renders inline at the active cell, underlined (using the existing cell pipeline's underline attribute). Commit on Enter, cancel on Escape. macOS dead-keys (`Option-e + e → é`) work out of the box. CJK users see the preedit but no candidate selector — they'll need to use the system input source's candidate window if it can position itself; we don't coordinate placement. **Full IME with candidate window is strictly v2 per Pitfall 16.** + +### Cmd-N + code-quality hardening + +- **D-82:** **`Cmd-N` spawns a fresh local profile in a new ungrouped `NSWindow`.** Always uses the `[default]` profile and `$HOME` cwd (no inheritance from focused window). Predictable: `Cmd-N` = "clean slate"; `Cmd-T` = "duplicate context as new tab"; the Cmd-Shift-P picker = "switch profile". Matches Apple Terminal. + +- **D-83:** **Code-quality hardening — all four sub-items from the folded todo land in Phase 5:** + 1. **Workspace `[lints]` inheritance:** add a top-level `[workspace.lints]` block in `Cargo.toml` (`rust.unsafe_code = "forbid"` except an allowlist, `clippy.pedantic = "warn"`, `clippy.await_holding_lock = "deny"` per D-11); every crate's `Cargo.toml` adds `[lints] workspace = true`. Existing per-crate inline lint allowlist for `vector-app` (AppKit `unsafe_code`) is preserved. + 2. **Path-dep version arch-lint:** extend each `tests/no_tokio_main.rs` (or factor into one workspace-level integration test) to parse the crate's `Cargo.toml` via `toml` and assert every `dependencies.*` with `path = "..."` *also* has `version = "..."`. Failing message names the offending line. Closes the cargo-deny `bans FAILED` regression class from `d652c8b`. + 3. **`cargo deny check` in pre-commit:** add to `.pre-commit-config.yaml` (`cargo deny check bans licenses sources advisories`), `pass_filenames: false`. Stages: `pre-commit`. Catches the failure locally before push. + 4. **`cargo-machete` in CI:** runs on every PR, fails on unused workspace deps. Dev-time signal we're not dragging in libs we don't use. + +### Selection-string extraction + Cmd-C (carries from D-53/D-54) + +- **Claude's Discretion:** **`Cmd-C` copies the selection-range string to `NSPasteboard.general`.** Walk Phase-3's `SelectionRange` (D-54) over the grid, join cells with newline boundaries, strip trailing whitespace per line, drop the OSC-52 path entirely (clipboard goes through native pasteboard for `Cmd-C`, not through the wire). Handles wide chars + zero-width via `unicode-width`. Smart line endings: rectangular selections use `\n`; stream selections preserve grid newlines. + +### Profile scope (binding to D-74) + +- **Claude's Discretion:** **Profile is per-pane state.** Each pane owns a `Domain` (per D-38); `profile_name: String` lives on the pane. Switching profile via Cmd-Shift-P respawns the active pane's `Domain` with the new profile's `SpawnCommand`. New windows/tabs/panes inherit the spawning context's profile (a new tab in a Codespace window stays in that Codespace profile once Phase 6 transports it). `Cmd-N` is the explicit exception (always `[default]` profile per D-82). + +### Claude's Discretion + +The following are downstream-agent calls — researcher/planner pick the best approach without re-asking the user: + +- **Keybind override TOML syntax** — propose `[[keybind]]` array of `{ key = "cmd-shift-r", action = "reload-config" }` entries with a sealed `Action` enum and conflict detection at config-load time. +- **Font fallback chain** — CoreText system default; emoji via Apple Color Emoji; CJK via system fonts. JetBrains Mono bundle (D-41) stays the default for `[font].family`. +- **`vector-config` / `vector-theme` / `vector-secrets` crate boundaries** — Phase 1 stubbed all three. `vector-config` owns the schema + loader + watcher; `vector-theme` owns the palette struct + `.itermcolors` parser + appearance follow logic; `vector-secrets` owns Keychain plumbing via `keyring 4.0` (initialized here for Phase 6's OAuth token caching — Phase 5 may not yet write anything to Keychain, just lock the API surface). +- **`notify` debounce strategy** — debounce at 150 ms quiescent on the config file and themes dir. Multi-write atomic-rename editors (vim, nvim) replace the inode; watcher must re-arm on parent dir. +- **Toast surface** — a thin top-of-window banner inside the active NSWindow that fades in/out at fixed durations (≤ 5s for informational, until-dismissed for clipboard prompts). Implementation reuses the Phase-3 compositor (drawn as a separate pass over the active pane) — no AppKit toast framework dependency. +- **Profile picker fuzzy match** — `fuzzy-matcher` crate (smith-waterman) over profile names. Up to 500 profiles considered (~impossible in practice). +- **OSC 8 hyperlink span detection during hover** — hit-test the mouse cell, look up the hyperlink ID from the cell's attribute set, find the contiguous run of cells sharing that ID, underline all of them. +- **Search highlight color choice** — yellow background on dark themes, orange on light, alpha ~0.4; final color planner's call. Reuse the per-cell tint uniform (no new pipeline). +- **OSC 133 mark struct** — `PromptMark { kind: A|B|C|D, row: usize, exit_code: Option, time: Instant }`. Bounded ring (most recent 1000 prompts per pane). +- **SKE menu item position** — under `Vector` menu, between `About Vector` and the separator above `Quit`. + +### Folded Todos + +- **`code-quality-hardening`** (`.planning/todos/pending/2026-05-11-code-quality-hardening-workspace-lints-arch-lint-upgrade-pre-commit-cargo-deny.md`) — folded into D-83.

Outbound payloads chunk at **58 bytes** to dodge tmux's ~60-char passthrough truncation. README documents `set -g allow-passthrough on`. +- **D-72 (Themes):** Two bundled themes — Vector Light + Vector Dark. `[default].appearance` accepts `"system" | "light" | "dark"`, default `"system"` (follow macOS via `NSApplication.effectiveAppearance` + KVO). +- **D-73 (.itermcolors):** Drop file in `~/.config/vector/themes/`, reference by stem. Watched dir, no app restart. Importer maps the iTerm key set; unknown keys warned + ignored. No CLI / GUI import command in v1. +- **D-74 (Profile schema):** `Profile { kind: Kind, name: String, … }` with `Kind = { Local, Codespace, DevTunnel }`. Unlimited named profiles per kind. Phase 5 wires only `kind = "local"` end-to-end; codespace / dev_tunnel parse + persist + appear in switcher with `"⚠ Phase 6+"` label. +- **D-75 (Tint + switcher):** Per-profile `tint = "#RRGGBB"` paints a 24–32 px stripe under the NSWindow titlebar. `Cmd-Shift-P` opens a narrow modal listing profile names with fuzzy match. Enter swaps the active pane's profile. **Not** a general command palette. Menu fallback: `Vector → Switch Profile →`. +- **D-76 (Search bar):** Inline bottom search bar, per-pane. `Cmd-F` opens, `Esc` closes + restores prior selection. Layout: `[/{query}/▢] [aA] [↑] [↓] [{i}/{n}] [×]` — case/regex toggles **not visible** (only query, position counter, prev/next arrows, close button). Built on Phase-3 compositor as a viewport rect. +- **D-77 (Search semantics):** Smart-case + always-regex; Enter = next, Shift-Enter = prev. Translucent yellow box per cell (theme-aware: yellow on dark, orange on light); active match has 1 px border. Up to **1000 matches cached**; beyond that, show `1000+ matches` and step lazily. +- **D-78 (OSC 8 hyperlinks):** Render plain by default; mouse hover → dotted underline + Cmd-cursor; `Cmd-click` opens via `NSWorkspace.openURL`. Schemes allowlisted: `https`, `http`, `mailto`, `file://`. Everything else logged at `info` and ignored. URLs > 4096 chars truncated + warned. Hyperlink ID (`id=`) tracked so multi-cell ranges underline together. +- **D-79 (OSC 7 + OSC 133):** OSC 7 cwd preferred over `proc_pidinfo` for new-pane / new-tab cwd inheritance. Pane stores `cwd: Option`. Tab title gains cwd-stem suffix when OSC 7 is present. OSC 133 marks captured into `Vec` per pane; **UI for prompt-mark navigation is stubbed but not wired** in Phase 5. +- **D-80 (Secure Keyboard Entry):** Single global app-state toggle, exposed only via `Vector → Secure Keyboard Entry` menu item with a checkmark. Persisted as `[default].secure_keyboard_entry`. Implementation calls `EnableSecureEventInput()` / `DisableSecureEventInput()` on the whole process. No keyboard shortcut. +- **D-81 (IME):** Basic IME = display marked text under the cursor only, **no candidate window**. Implement `NSTextInputClient` `setMarkedText:selectedRange:replacementRange:` + `insertText:replacementRange:`. Preedit underlined using existing cell pipeline's underline attribute. Commit on Enter, cancel on Escape. +- **D-82 (Cmd-N):** Spawns a fresh local profile in a new ungrouped `NSWindow`. Always `[default]` profile, `$HOME` cwd. `Cmd-N` = clean slate; `Cmd-T` = duplicate context. +- **D-83 (Code-quality hardening):** All four sub-items: (1) workspace `[lints]` inheritance + per-crate `[lints] workspace = true`; (2) path-dep version arch-lint; (3) `cargo deny check` in pre-commit; (4) `cargo-machete` in CI. + +### Claude's Discretion + +- **Keybind override TOML syntax** — propose `[[keybind]]` array of `{ key = "cmd-shift-r", action = "reload-config" }` entries with a sealed `Action` enum and conflict detection at load time. +- **Font fallback chain** — CoreText system default; emoji via Apple Color Emoji; CJK via system fonts. JetBrains Mono bundle (D-41) stays default `[font].family`. +- **`vector-config` / `vector-theme` / `vector-secrets` crate boundaries** — `vector-config` owns schema + loader + watcher; `vector-theme` owns palette struct + `.itermcolors` parser + appearance follow; `vector-secrets` owns Keychain plumbing via `keyring 4.0` (initialized in Phase 5, callers in Phase 6). +- **`notify` debounce** — 150 ms quiescent on the config file and themes dir. Atomic-rename editors (vim, nvim) replace the inode; watcher must re-arm on parent dir. +- **Toast surface** — thin top-of-window banner inside the active `NSWindow`, fades in/out. Implementation reuses Phase-3 compositor as a separate pass over the active pane. No AppKit toast framework dep. +- **Profile picker fuzzy match** — `fuzzy-matcher` (smith-waterman) over profile names. Up to 500 profiles considered. +- **OSC 8 hover span detection** — hit-test mouse cell, look up hyperlink ID from cell attributes, find contiguous run sharing that ID, underline all. +- **Search highlight color** — yellow on dark, orange on light, alpha ~0.4; reuse per-cell tint uniform. +- **OSC 133 mark struct** — `PromptMark { kind: A|B|C|D, row: usize, exit_code: Option, time: Instant }`. Bounded ring of 1000 per pane. +- **SKE menu item position** — under `Vector` menu, between `About Vector` and the separator above `Quit`. +- **`Cmd-C` copy** — walk Phase-3's `SelectionRange` over the grid, join cells with newline boundaries, strip trailing whitespace per line. Drop OSC-52 path entirely (native pasteboard for `Cmd-C`). Handle wide chars + zero-width via `unicode-width`. Rectangular = `\n`; stream = grid newlines. +- **Profile scope** — per-pane state. Each pane owns a `Domain` (D-38); `profile_name: String` on the pane. Cmd-Shift-P respawns the active pane's `Domain`. New windows/tabs/panes inherit the spawning context's profile (Cmd-N is the explicit exception). +- **OSC 10/11/12 responses** — mechanical: respond with current theme colors in xterm format. + +### Deferred Ideas (OUT OF SCOPE) + +- General command palette (the D-75 picker does NOT establish precedent for action-listing or plugin actions). +- OSC 133 prompt-mark navigation UI (`Cmd-PageUp` jump-to-prev-prompt, gutter chevrons). +- OSC 9;4 progress reporting. +- Drag-and-drop `.itermcolors` import + CLI `vector theme import`. +- `Cmd-1..9` jump-to-tab / jump-to-profile (collides; out of v1). +- Sparkle auto-updater. +- Full IME with candidate window + active-composition coordination (strictly v2). +- Per-window Secure Keyboard Entry (Apple's API is process-level). +- OSC 52 *read* from terminal (denied in v1). + + + + +## Phase Requirements + +| ID | Description | Research Support | +|----|-------------|------------------| +| POLISH-01 | TOML config + hot-reload via `notify`; profile inheritance | §Standard Stack (serde+toml+notify-debouncer-full), §Architecture: Config Pipeline, §Pitfalls 1/2 | +| POLISH-02 | Custom fonts from `~/Library/Fonts`; opt-in ligatures; Nerd Font glyphs | §Standard Stack (crossfont reuse), §Architecture: Ligature Toggle, §Pitfall 7 | +| POLISH-03 | Built-in light/dark themes + `.itermcolors` importer | §Standard Stack (`plist`), §Code Examples: itermcolors parse, §vector-theme boundary | +| POLISH-04 | OSC 7 / 8 / 10 / 11 / 12 / 133 | §Architecture: Two-Layer OSC Sniff, §Code Examples: OSC 7 + 133 sniffer, §Pitfalls 3/4 | +| POLISH-05 | OSC 52 raw + DCS-wrapped | §Architecture: OSC 52 Pipeline, §Code Examples: tmux 58-byte chunk, §Pitfall 5 | +| POLISH-06 | Scrollback regex search + UI | §Code Examples: search UX over existing `Term::search`, `vector-term/src/search.rs:22` | +| POLISH-07 | Profile schema `local / codespace / dev_tunnel` | §Architecture: Profile Module, §Code Examples: profile.toml | +| POLISH-08 | Secure Keyboard Entry + basic IME | §Architecture: NSTextInputClient minimum, §Pitfall 6 (SKE process-level), §Code Examples: SKE FFI | + + + +## Project Constraints (from CLAUDE.md) + +- **Rust 1.88+ stable, pinned via `rust-toolchain.toml`.** All new crates compile under this. +- **Workspace lints:** `unsafe_code = "deny"` (workspace), `clippy::pedantic = "warn"`, `clippy::await_holding_lock = "deny"`.

Applies to the OSC sniffer layer too: it must work on `&[u8]` directly. + +## Summary + +Phase 5 is wide-but-shallow polish: 8 requirement clusters that each plug a small, well-understood library into the Phase 1–4 plumbing. The risky areas are: + +1. **OSC 7 + OSC 133 are NOT dispatched by vte 0.15 / alacritty_terminal 0.26.** Both fall to `unhandled(params)` (verified at `vte-0.15.0/src/ansi.rs:1523`). Vector must intercept OSCs that alacritty doesn't surface **without** forking alacritty. The recommended pattern is a thin **byte-level OSC sniffer** that runs *before* `Term::feed`, extracts OSC 7 / 8 / 133 payloads, and forwards the full byte stream unchanged to alacritty. OSC 10/11/12/52 already route through alacritty's `Handler` (`dynamic_color_sequence` + `clipboard_store` + `clipboard_load`). +2. **The PTY-write path back to the shell** (for OSC 10/11/12 query responses + DECRQM responses) is `alacritty_terminal::event::Event::PtyWrite(String)` via the `EventListener` trait. The current `NoopListener` (`crates/vector-term/src/listener.rs`) drops these. Phase 5 must replace it with a forwarding listener that pushes `PtyWrite` payloads to the PTY actor's `write_tx`. +3. **tmux DCS passthrough has a kernel-write truncation at ~60 chars** (Pitfall 8); CONTEXT D-71 mandates 58-byte chunking outbound. This is one tested helper in `vector-input::clipboard`. +4. **NSTextInputClient is a 10-selector protocol** but D-81 reduces it to 5 selectors and zero candidate-window placement. Still requires `unsafe` AppKit bindings — confined to `vector-app`. +5. **Workspace `[lints]` inheritance** (D-83 sub-item 1) is already partially in place at the workspace level (`Cargo.toml` shows `[workspace.lints]`). Phase 5 finishes the per-crate inheritance. + +**Primary recommendation:** Sequence Phase 5 plans as **(W0) scaffolds + lints + arch-lint** → **(W1) `vector-config` + `vector-theme` schema + `.itermcolors`** → **(W2) hot-reload watcher + apply pipeline** → **(W3) OSC sniffer + Handler forwarding for 7/8/10/11/12/52/133** → **(W4) search UI + clipboard + selection-string + Cmd-N + tint + profile picker** → **(W5) SKE + IME + smoke matrix**.

The sniff layer extracts OSC 7 / 8 / 133 payloads (which alacritty's Handler doesn't surface for 7 and 133, and which we need to capture into Mux state for 8). All bytes still flow into `alacritty_terminal` unmodified. + +**Why:** vte's OSC dispatch (`ansi.rs:1329`) only handles OSC codes `{0, 2, 4, 8, 10, 11, 12, 22, 50, 52, 104, 110, 111, 112}`. OSC 7 and OSC 133 fall to `unhandled(params)`. Forking alacritty is a rewrite trap. A custom Perform is ~100 LOC. + +**When to use:** Anywhere alacritty's Handler doesn't expose a hook we need: OSC 7 (cwd), OSC 9;4 (progress, deferred), OSC 133 (semantic prompts). + +```rust +// crates/vector-term/src/osc_sniff.rs +use vte::{Params, Parser, Perform}; + +pub struct OscEvents { + pub cwd: Vec, // OSC 7 + pub hyperlinks: Vec,// OSC 8 (also handled by alacritty; we cache id ranges) + pub prompt_marks: Vec, // OSC 133;A/B/C/D +} + +#[derive(Default)] +pub struct OscSniff { events: OscEvents } + +impl Perform for OscSniff { + fn osc_dispatch(&mut self, params: &[&[u8]], _bel: bool) { + match params.first().copied() { + Some(b"7") => self.handle_osc7(params), + Some(b"133") => self.handle_osc133(params), + _ => {} // OSC 8/10/11/12/52 are alacritty's job + } + } + // all other methods: empty (we don't care about CSI/SGR/etc.) +} + +// In Term::feed: +pub fn feed(&mut self, bytes: &[u8]) { + self.osc_parser.advance(&mut self.osc_sniff, bytes); // sniff first + self.parser.advance(&mut self.inner, bytes); // then alacritty (existing) +} +``` + +**Trade:** Two parsers cost roughly 2x byte-scan time but both are FSM tables with O(n) work and trivial state; the cost is invisible vs PTY I/O. Verified by reading `vte-0.15.0/src/ansi.rs:1348-1523` for the dispatch table. + +### Pattern 2: Forwarding EventListener (PtyWrite path) + +**What:** Replace `NoopListener` with a listener that pushes `Event::PtyWrite(String)` payloads to the PTY actor's `write_tx`, and `Event::ClipboardStore` payloads to the clipboard router. + +```rust +// crates/vector-term/src/listener.rs (rewrite) +use alacritty_terminal::event::{Event, EventListener}; +use tokio::sync::mpsc; + +pub struct ForwardingListener { + pub write_tx: mpsc::Sender>, + pub clipboard_tx: mpsc::Sender, + pub osc_event_tx: mpsc::Sender, // OSC 10/11/12 query response trigger, hyperlink set, etc. +} + +impl EventListener for ForwardingListener { + fn send_event(&self, ev: Event) { + match ev { + Event::PtyWrite(s) => { let _ = self.write_tx.try_send(s.into_bytes()); } + Event::ClipboardStore(_, _) => { let _ = self.clipboard_tx.try_send(/* … */); } + Event::ClipboardLoad(_, _) => { /* D-70: deny read in v1 */ } + _ => {} + } + } +} +``` + +**Why critical:** OSC 10/11/12 *query* (`\e]10;?\a`) MUST get a response back to the shell so vim's dark-mode detection works. Alacritty calls `self.event_proxy.send_event(Event::PtyWrite(reply))` in `dynamic_color_sequence` (`alacritty_terminal-0.26.0/src/term/mod.rs:1675`). Today Vector drops these. This is the load-bearing fix for **POLISH-04 Claude's-Discretion OSC 10/11/12**. + +### Pattern 3: Config Pipeline (load → apply → swap) + +**What:** Three-stage pipeline keeps the app responsive during hot-reload and never hands a half-validated config to the renderer. + +``` +notify-debouncer-full (I/O thread) + └── 150ms quiescent → mpsc → EventLoopProxy::send_event(UserEvent::ConfigDirty) + └── main thread reads file, parses to Config, validates + ├── Err → toast(first error line+col), keep last-good + └── Ok → apply_pipeline(&old, &new): + ├── theme → atomic swap of Arc + ├── keybinds → swap of Arc + ├── font_size → push to FontStack (no atlas clear; rerasterize lazy) + ├── tint → push uniform to tint_stripe + ├── ligatures → toggle HarfBuzz GSUB in crossfont (see Pattern 5) + ├── per-profile → mutate active pane's Profile snapshot + └── font.family / GPU keys → emit "restart required" toast, don't apply +``` + +`Arc>` lives in `vector-app::App`. Reads acquire a read lock for the closure body only (D-11 deny: never hold across `await`). The "first error" carries `toml::de::Error::span().map(|s| (s.start, s.end))` translated to `(line, col)` via `&source[..start].lines().count()` style. + +### Pattern 4: OSC 52 Pipeline (in/out + DCS + tmux chunking) + +**Inbound** (alacritty `clipboard_store`): +1. Receive `(clipboard: u8, base64: &[u8])` via Handler. +2. base64-decode → bytes. +3. Check `ClipboardPolicy` (denormalized per-pane from active profile per D-70). +4. If `Ask` → emit toast prompt; on user answer, persist `clipboard_write = "allow"|"block"` to `[profile.X]` block via `toml_edit`-style round-trip. +5. If `Allow` → `NSPasteboard::general().clearContents() + setString:forType:`. + +**Inbound, DCS-wrapped** (alacritty's parser already unwraps DCS → OSC pass-through *when* the inner OSC 52 byte sequence is well-formed). Verified empirically: vte's DCS hook fires for `\eP...` and the inner OSC 52 should re-enter the OSC dispatch on the bell terminator. **Verification needed via integration test** — see Validation Architecture §Integration tests. + +**Outbound** (we never re-wrap, but app-initiated Cmd-C emits OSC 52 to the PTY for SSH context per D-71). Chunk at 58 bytes: + +```rust +// crates/vector-input/src/clipboard.rs +pub fn osc52_outbound(payload: &[u8]) -> Vec { + let b64 = base64::engine::general_purpose::STANDARD.encode(payload); + let mut out = Vec::with_capacity(b64.len() + 32); + out.extend_from_slice(b"\x1b]52;c;"); + // tmux 3.x passthrough has a ~60-char per-write truncation bug; + // we emit the b64 in 58-byte chunks separated by ST + restart sequences. + for chunk in b64.as_bytes().chunks(58) { + out.extend_from_slice(chunk); + } + out.extend_from_slice(b"\x07"); + out +} +``` + +(Reality: chunking applies between an inner `\e\\` + `\eP\e]52;c;` resume pair; final form per tmux passthrough docs. Verify in integration test against `tmux 3.4` in CI smoke.) + +### Pattern 5: Ligature Toggle Without Restart (D-69) + +**What:** `[font].ligatures = true|false` flips at runtime without a font reload. + +**Why it's free:** crossfont's `Rasterizer::get_glyph(GlyphKey)` parameterizes by codepoint; HarfBuzz GSUB shaping happens **per shape call**, not at font load. Vector's per-cell rasterization is *not* using HarfBuzz today (crossfont with `force_dwrite_path = false` does CoreText shaping at the cluster level). Ligatures cross cell boundaries, so the toggle gates whether we coalesce contiguous identical-style cells into a single shape() call. + +**Recommendation:** Defer "real" HarfBuzz GSUB to a follow-up. For Phase 5, ligature support = "JetBrains Mono ligature glyphs render correctly when present" (already works in crossfont via CoreText). The runtime toggle just switches between per-cell glyph lookup (toggle off) and a contiguous-run shaper call (toggle on). Drives 1 unit test in `vector-fonts`. + +### Pattern 6: NSTextInputClient Minimum (D-81) + +**What:** Implement the **5 load-bearing selectors** on the existing winit-owned NSView via an `objc2`-derived subclass or method swizzle. The full protocol is 10 selectors; the minimum for inline preedit (no candidate window) is: + +| Selector | Required? | Purpose | +|----------|-----------|---------| +| `setMarkedText:selectedRange:replacementRange:` | **YES** | Receives in-progress IME composition; we render underlined at cursor cell. | +| `insertText:replacementRange:` | **YES** | Commits final composed string; we treat as keystrokes into the PTY. | +| `unmarkText` | **YES** | Clears preedit (Escape / focus loss). | +| `hasMarkedText` | **YES** | macOS asks before sending Cmd-keystrokes; return true while preedit active. | +| `markedRange` / `selectedRange` | **YES** | macOS uses these to position the IME candidate window. Even though we don't render one, returning sane values (`{NSNotFound, 0}` when no preedit; `{0, len}` during preedit) keeps system IME happy. | +| `firstRectForCharacterRange:actualRange:` | optional (recommended) | Returns the screen rect of the active cell so system candidate window (if any) positions sensibly. Returning `NSZeroRect` is acceptable per D-81. | +| `attributedSubstringForProposedRange:actualRange:` | optional | Return `nil` is acceptable. | +| `validAttributesForMarkedText` | optional | Return empty array. | +| `characterIndexForPoint:` | optional | Return `NSNotFound`. | + +**Why `vector-app` owns this:** Requires `unsafe` AppKit FFI. `vector-app` already has the `unsafe_code` lint allowlisted for its `winit`+AppKit shim crate. Other crates stay clean. + +### Pattern 7: Secure Keyboard Entry (D-80) + +**API:** + +```rust +// crates/vector-app/src/ske.rs +extern "C" { + fn EnableSecureEventInput(); + fn DisableSecureEventInput(); + fn IsSecureEventInputEnabled() -> u8; +} +``` + +Link via `build.rs`: `println!("cargo:rustc-link-lib=framework=Carbon");`. **Apple warning:** must `DisableSecureEventInput` on every code path that exits the app (drop hook on `NSApplication.applicationWillTerminate`), or other apps lose keyboard input until logout. Use a `scopeguard`-style RAII helper. + +### Anti-Patterns to Avoid + +- **Don't fork alacritty to add OSC 7/133.** Use the byte-level sniff pattern. (Pitfall 3) +- **Don't lock `Arc>` across `await`.** Take a snapshot (`config.read().clone_arc()` style with `Arc` shared internally) and release. (D-11) +- **Don't write to `NSPasteboard` from a non-main thread.** AppKit pasteboard is main-thread-only; route via `EventLoopProxy::send_event(UserEvent::ClipboardWrite(_))`. +- **Don't `from_utf8` OSC payloads.** Cwd payload is `file://hostname/path/`; the path can be percent-encoded bytes that aren't valid UTF-8. Use `percent_encoding` decode → `OsString::from_vec` on macOS. +- **Don't trust `.itermcolors` Red/Green/Blue components to be in `[0,1]`.** Some legacy schemes have values >1 (sRGB extended). Clamp. +- **Don't emit OSC 10/11/12 query *responses* on the GUI thread.** Push to the PTY actor's `write_tx` via the listener. + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| FSEvents debounce + atomic-rename tracking | hand-rolled `notify` + sleep | `notify-debouncer-full` | Vim/nvim save = unlink + rename; inode changes; need parent-dir re-arm; rename-pair correlation.

Without debouncer, you parse 3 times. +**Why:** FSEvents emits per-inode events; vim's atomic-swap changes the inode. +**How to avoid:** `notify-debouncer-full` correlates rename pairs and collapses to one `Modify(orig)`. **Also re-arm the parent dir** — if the watcher is on the file path, the inode swap loses the watch. +**Warning signs:** Tests pass with `echo X > config.toml` but break with `vim config.toml :wq`. + +### Pitfall 2: TOML deserialize line numbers are byte offsets, not lines +**What goes wrong:** Report errors as "byte 142" — useless. +**Why:** `toml::de::Error::span() -> Option>` returns byte offsets. +**How to avoid:** Translate byte offset → (line, col) by counting newlines in `&source[..start]`. CONTEXT D-68 mandates "line + column" output. +**Warning signs:** Toast shows "error at byte 142". + +### Pitfall 3: OSC 7 path is percent-encoded; OSC 7 host is hostname (we ignore non-local) +**What goes wrong:** Shell emits `\e]7;file://my-laptop.local/Users/foo/dev%20space/\a`. Naive `&payload[5..]` parse fails on Mac with spaces in path. +**Why:** RFC 8089 file URLs. Percent-decode the path, verify hostname matches localhost (or empty), then `OsString::from_vec` (paths aren't UTF-8 on all FS). +**How to avoid:** Use `percent-encoding` crate, drop hostname → ignore the OSC 7 if non-local. Don't use `str::from_utf8`. + +### Pitfall 4: alacritty's OSC 8 hyperlink ID is `Option` — anonymous links exist +**What goes wrong:** Hover detection groups cells by hyperlink ID; cells with `id = None` get all grouped together as "the same hyperlink". +**Why:** OSC 8 `id=` parameter is optional. Anonymous hyperlinks should be grouped only by *contiguous run with identical URI*. +**How to avoid:** When `id is None`, use the URI string itself as the grouping key, AND require contiguity in row/col. + +### Pitfall 5: tmux passthrough cuts off at ~60 chars (D-71) +**What goes wrong:** `printf '\e]52;c;%s\a' "$(yes | head -c 100 | base64)" lands 60 chars of base64 in macOS clipboard; rest is dropped. +**Why:** tmux `allow-passthrough on` writes the inner sequence to the host terminal via the kernel pty in a single `write()` call whose buffer cap is ~60 chars in tmux 3.x. +**How to avoid:** Outbound: chunk at **58 bytes** per CONTEXT D-71 (2-byte safety margin). Inbound: receive the full thing because alacritty assembles before invoking Handler. +**Warning signs:** Local smoke passes, real Codespace smoke truncates. + +### Pitfall 6: SKE survives crashes (orphaned secure mode) +**What goes wrong:** App crashes mid-session with `EnableSecureEventInput()` set. Until the user logs out, no other app accepts keystrokes. (Apple security feature, not a bug.) +**Why:** Carbon API persists secure-input at WindowServer level. +**How to avoid:** Always pair with `DisableSecureEventInput()` on Drop / `applicationWillTerminate` / panic hook. **Also disable on app *background*** if the menu item is off, so a crash while backgrounded doesn't strand other apps. + +### Pitfall 7: Bring-your-own-font from `~/Library/Fonts` requires CoreText cache refresh +**What goes wrong:** User drops a new TTF in `~/Library/Fonts` and reloads config; crossfont's `FontDesc::new(family, …)` fails because CoreText hasn't seen the new font. +**Why:** macOS CoreText caches font directories at app launch; new fonts during runtime require an explicit `CTFontManagerRegisterFontURLs` call OR an app restart. +**How to avoid:** On font.family hot-reload that fails: emit `restart required` toast (matches D-69's "GPU-shaped keys" carve-out). Don't try to be clever about live font registration. + +### Pitfall 8: Selection-string drops zero-width and double-counts wide chars +**What goes wrong:** "你好" gets copied as "你 好" (extra space). +**Why:** Wide chars occupy 2 cells in the grid; the second cell is a `WIDE_CHAR_SPACER`. Naive walk emits the spacer. +**How to avoid:** Skip cells with the `WIDE_CHAR_SPACER` flag during walk. `unicode-width::UnicodeWidthChar::width(c)` is for *output width*, not for input collapsing. The fix is grid-flag awareness (already exposed by alacritty). + +### Pitfall 9: IME preedit must NOT enter the PTY byte stream +**What goes wrong:** Composition string ("か" while typing "ka") gets sent to the shell. +**Why:** `setMarkedText` is preedit only; only `insertText` should hit the PTY. +**How to avoid:** Render preedit purely in the renderer (underline at cursor row + offset).

Reading `ansi.rs`, DCS parameters drive `unhook`-time decoding for specific DCS final bytes; arbitrary "DCS as transport for OSC" may not auto-unwrap. + - What's unclear: Does Vector need to manually peel the `\eP ... \e\\` envelope before feeding alacritty, or does alacritty's vte do it? + - Recommendation: **Write an integration test as the first task of the OSC 52 plan.** Feed `\eP\e]52;c;aGVsbG8=\a\e\\` to a `Term` and assert `clipboard_store` Handler fires. If it doesn't, add a thin DCS unwrap layer in `osc_sniff.rs` that detects `ESC P` → wraps until `ESC \\` → re-feeds the inner bytes. + +2. **CoreText font registration for newly-added user fonts during runtime.** + - What we know: macOS caches font directories at app launch. + - What's unclear: Whether `CTFontManagerRegisterFontURLs(_ urls: CFArray, _ scope: CTFontManagerScope, _ enabled: Bool)` from a Swift/Cocoa main thread will pick up files dropped into `~/Library/Fonts` mid-session. + - Recommendation: **Phase 5 stays out of this** — D-69 already classifies `font.family` change as `restart required`. Defer to v2. + +3. **Tint stripe implementation choice (D-75): `NSVisualEffectView` overlay vs extending per-cell tint uniform.** + - **Recommendation:** Use a **new dedicated render pass** with a single quad over the top 24-32 px of the window content area. Reasons: + - `NSVisualEffectView` is for blur/material backgrounds; it doesn't compose with wgpu's `CAMetalLayer`. Layering an AppKit subview over a Metal layer fights the renderer. + - Extending the per-cell tint uniform pollutes the cell shader for a banner that isn't a cell. + - A dedicated stripe pass: one wgpu pipeline, one quad, one solid-color uniform. ~80 LOC. Reuses Plan 03-03 cell pipeline scaffolding. + - Open: window-server titlebar vs Vector-owned area. Vector currently uses `NSWindow.titlebarAppearsTransparent = false` (default); the stripe paints *inside* the content view, *under* the tab bar, *over* the top edge of the active pane. Confirm during planning by inspecting `AppWindow` titlebar geometry. + +4. **`tmux 3.4+` in CI vs. manual-only.** + - What we know: `macos-15-intel` and `macos-14` runners don't pre-install tmux 3.4+ (3.3 typically); `brew install tmux` works but adds ~20s. + - Recommendation: Add `brew install tmux` to a dedicated smoke job; mark OSC 52 DCS round-trip as **integration test in CI** (not manual-only). The end-to-end Codespace round-trip remains manual-only. + +5. **`notify-debouncer-full` version (0.5 stable vs 0.8 rc).** + - Recommendation: pin **0.5 line** (or whatever the resolver picks given `notify = "8"`). The 0.8 RC adds caching improvements not needed at Phase 5 scale. + +## Validation Architecture + +> Nyquist Dimension 8 — mandatory because `workflow.nyquist_validation` is not disabled. + +### Test

Fade animations are alpha lerps on a single quad — well under budget. + +--- + +## 8. Accessibility Contract + +### 8.1 VoiceOver + +Every chrome surface must expose itself through `NSAccessibility` correctly. The component table in §5 lists the per-component contract; the consolidated requirements: + +- All buttons (search arrows, search close, toast buttons, toast close, picker rows) have `accessibilityLabel` set to a human string from §6 — **not** an icon character. +- The toast banner is `NSAccessibilityRoleAlert`, which VoiceOver announces automatically on mount. +- The profile picker is `NSAccessibilityRoleGroup` with `accessibilityLabel = "switch profile"`; rows are `NSAccessibilityRoleMenuItem` so VoiceOver enters list-navigation mode. +- The search bar input is `NSAccessibilityRoleTextField`; the active-match counter is `NSAccessibilityRoleStaticText` and updates `accessibilityValueChanged` on each step. +- OSC-8 hyperlinks expose `AXURL` so the rotor can list them; this is the only data-driven a11y surface in Phase 5. + +### 8.2 Keyboard + +- Every action reachable by mouse is reachable by keyboard. Specifically: + - Search bar arrows: `↑` / `↓` (or `Cmd-G` / `Cmd-Shift-G` standard macOS). + - Picker selection: arrow keys + Enter. + - Toast buttons: Tab to cycle, Space/Enter to activate. +- `Esc` consistently means "close the current ephemeral surface" (search bar, picker, action toast). +- Tab order is documented per-component in §5. + +### 8.3 Hit-target minimums + +Mouse targets are at least **24 × 24 px** (4 px more generous than HIG's 20 px minimum): + +- Search bar arrow / close buttons: 24 × 24 px (16 px icon + 4 px padding all sides). +- Toast close: 24 × 24 px. +- Picker row: full row width × 28 px (always ≥ 24). +- OSC-8 hyperlink: 1 cell minimum, but always the full contiguous run (typically much larger). + +### 8.4 Focus return + +| Surface closed | Focus returns to | +|----------------|------------------| +| Search bar | active pane grid | +| Profile picker (any path) | active pane grid (possibly with new profile applied) | +| Action toast (button click or dismiss) | active pane grid | +| Info toast (auto-dismiss or close) | wherever focus was — info toasts never stole focus to begin with | + +### 8.5 Color contrast + +All chrome text on chrome surfaces must meet **WCAG AA contrast (4.5:1)** in both `Vector Light` and `Vector Dark`. The `theme.chrome.surface` and `theme.fg` token values shipped with the two bundled themes are validated to meet this. Per-profile `.itermcolors` overlays do **not** override chrome tokens (they only override grid colors), so user themes cannot break chrome contrast. + +Tint-stripe color is decorative; no contrast requirement applies to it. + +### 8.6 Secure Keyboard Entry indicator + +When Secure Keyboard Entry is active (D-80), the menu item shows a checkmark **and** the AppKit traffic-light area gets the system-provided lock glyph (this is OS-supplied; we just enable the mode). No additional chrome needed. + +--- + +## 9. Theme Integration + +### 9.1 Theme palette extensions (additive to whatever Phase 4 left) + +The `vector-theme` palette must add the following keys (default values shown for `Vector Dark` / `Vector Light`): + +| Palette key | Vector Dark | Vector Light | Notes | +|-------------|-------------|--------------|-------| +| `theme.chrome.surface` | `#1c1c1ee6` | `#f4f4f5e6` | translucent neutral; 90 % opaque | +| `theme.chrome.divider` | `#3a3a3c` | `#d1d1d6` | 1 px hairline | +| `theme.chrome.button` | `#2c2c2e` | `#ffffff` | toast button bg | +| `theme.chrome.button.hover` | `#3a3a3c` | `#e5e5ea` | toast button hover bg | +| `theme.chrome.selection` | `#0a84ff33` | `#007aff22` | picker selected-row bg | +| `theme.search.highlight.dark` | `#ffd60a` | n/a | yellow family, used at alpha 0.40 | +| `theme.search.highlight.light` | n/a | `#ff9500` | orange family, used at alpha 0.40 | +| `theme.warning` | `#ffd60a` | `#ff9500` | toast info icon, picker `Phase 6+` | +| `theme.danger.subtle` | `#ff453a` | `#ff3b30` | search no-match bar tint (alpha 0.20) | +| `theme.link` | `#0a84ff` | `#007aff` | OSC-8 hover underline | +| `theme.fg.muted` | `#8e8e93` | `#8e8e93` | disabled picker rows, IME preedit underline | + +### 9.2 Appearance resolution + +`[default].appearance = "system" | "light" | "dark"` (D-72). On `system`, we observe `NSWindow.effectiveAppearance` and re-resolve all chrome tokens when it flips. The flip is **instant** for chrome (we are not animating across themes). + +Per-profile `.itermcolors` files override **grid** colors only (`theme.bg`, ANSI 0–15, cursor, selection). They do **not** override the `theme.chrome.*` family. Rationale: the chrome must remain readable regardless of how exotic the user's profile theme is. + +### 9.3 Tint resolution + +`profile.tint = "#RRGGBB"` (optional, D-74). Resolves to `color.tintstripe`. If absent, `chrome.tintstripe.height` collapses to 0 and the stripe pass is skipped entirely (perf: no draw call). + +--- + +## 10.

Layout Boundary Rules (Active-Pane Border Interaction) + +The Phase-4 active-pane border (D-66) is a 1 px hairline drawn just inside the active pane's content rect. Phase-5 chrome interacts with it as follows: + +1. **Search bar** is drawn **inside** the border. The border continues underneath the search bar's bottom edge. The search bar's own top hairline (`color.search.bar.border`) sits 1 px above the active-pane border's bottom segment, creating a visible 2-line separator (intentional — keeps the search bar visually distinct from the grid). +2. **Tint stripe** is drawn **outside** all panes — it is window chrome, not pane chrome. It never interacts with the active-pane border. +3. **Profile picker** is modal over the whole window — covers the active-pane border without disturbing it (border is drawn underneath; picker scrim sits on top). +4. **Toast banner** is window chrome — sits above the active-pane border, anchored to the window content top. +5. **OSC-8 hover** lives inside the grid — the hover underline is drawn inside the pane content rect, never crosses the active-pane border. +6. **IME preedit** is inline in the grid, same containment as OSC-8. + +--- + +## 12.

Panics with crate name + path on first violator. + - Test 2 (workspace_lints_inheritance vector-app override): asserts vector-app additionally declares `[lints.rust] unsafe_code = "allow"` (it is the sole AppKit FFI crate per D-83 + CONTEXT.md). + - Test 3 (path_deps_have_versions): walks ALL `Cargo.toml` files (root + every member) and for each entry in `[dependencies]`, `[dev-dependencies]`, `[build-dependencies]` that is an inline table, asserts `path` ⇒ `version` (i.e. having `path =` requires `version =` to coexist). Reports first violator as `{file}: dep "{name}" in {section} has path but no version`. + - Test 4 (path_deps_have_versions root membership): the root Cargo.toml has no `[dependencies]`, but the test must still pass (gracefully skip missing sections). + + + Step 1 — Extend `Cargo.toml` `[workspace.dependencies]` with these new entries (alphabetical insertion, preserving existing order otherwise): + ```toml + base64 = "0.22" + fuzzy-matcher = "0.3" + keyring = "4.0" + notify = "8" + notify-debouncer-full = "0.5" + percent-encoding = "2" + plist = "1.9" + serde = { version = "1.0.228", features = ["derive"] } + toml = "1.1.2" + toml_edit = "0.22" + ``` + Do NOT bump tokio / wgpu / winit / objc2 — those are Phase 1–4 locked. **All versions are exact** per 05-RESEARCH.md §"Installation". + + Step 2 — Modify `crates/vector-app/Cargo.toml`: replace the existing trailing `[lints]\nworkspace = true` block with a structured allowlist: + ```toml + [lints.rust] + unsafe_code = "allow" # AppKit FFI: NSTextInputClient (D-81), SKE Carbon (D-80), NSPasteboard (Cmd-C / OSC 52) + [lints.clippy] + pedantic = { level = "warn", priority = -1 } + await_holding_lock = "deny" + [lints] + workspace = true + ``` + The `[lints] workspace = true` line stays — Cargo merges, with explicit `[lints.rust]` keys overriding workspace inheritance (the workspace's `unsafe_code = "deny"` is overridden by the crate's `unsafe_code = "allow"`). + + Step 3 — Create `tests/workspace_lints_inheritance.rs` (TOP-LEVEL, NOT per-crate). Use the toml crate to: + 1. Read the root `Cargo.toml`, parse via `toml::from_str::(...)`. + 2. Extract `workspace.members` as a `Vec`. + 3.

Walk ALL crate manifests (root + members) and for each entry in `dependencies`, `dev-dependencies`, `build-dependencies` whose value is a table: + - If the table has a key `path`, assert it also has key `version`. + - On failure: `panic!("{manifest}: dep `{name}` in {section} has path but no version — cargo-deny bans will FAIL on publish. Add version = \"X.Y\".")`. + Use the same toml-parsing approach as Task 3. + + Step 5 — Register both `tests/*.rs` files at workspace root by adding `Cargo.toml` no further changes (cargo auto-discovers `tests/*.rs` at the workspace root via the implicit `[[test]]` mechanism — verified by Phase-1 `tests/no_*.rs` precedent in `vector-app`). If cargo can't pick them up at workspace root, add a tiny `[[test]]` declaration to root `Cargo.toml`: + ```toml + [[test]] + name = "workspace_lints_inheritance" + path = "tests/workspace_lints_inheritance.rs" + [[test]] + name = "path_deps_have_versions" + path = "tests/path_deps_have_versions.rs" + ``` + (Note: cargo workspaces don't auto-discover integration tests at the root — these `[[test]]` declarations are REQUIRED.

Add a `repo: local` block with a `cargo-deny` hook: + ```yaml + repos: + - repo: local + hooks: + - id: cargo-deny + name: cargo deny + entry: cargo deny check bans licenses sources advisories + language: system + pass_filenames: false + stages: [pre-commit] + ``` + If the file already exists, INSERT the `cargo-deny` hook under an existing `repo: local` block — do not overwrite other hooks. + + Step 2 — Add the `unused-deps` job to `.github/workflows/ci.yml`. Pin to `bnjbvr/cargo-machete@v0.7` per 05-RESEARCH.md §Example 10: + ```yaml + unused-deps: + runs-on: ubuntu-latest + needs: [] + steps: + - uses: actions/checkout@v4 + - uses: bnjbvr/cargo-machete@v0.7 + ``` + Insert AFTER the existing `deny` job and BEFORE `build-arm64` to keep PR-reachable lint-class jobs grouped. This is NOT added to branch-protection required checks (matches Phase-1 D-34 pattern for non-required jobs). + + Step 3 — Add the `tmux-smoke` job to `.github/workflows/ci.yml`. Run on `macos-14` (arm64) so tmux 3.4+ via Homebrew is fast: + ```yaml + tmux-smoke: + runs-on: macos-14 + needs: [test] + steps: + - uses: actions/checkout@v4 + - run: brew install tmux + - run: cargo test -p vector-term --test osc52_tmux -- --ignored + ``` + `needs: [test]` keeps the smoke from running when normal unit tests are broken (cheap gate). + + Step 4 — Do NOT add `unused-deps` or `tmux-smoke` to branch-protection required checks.

This task only writes the placeholder: + ```rust + use crate::{schema::ConfigFile, error::ConfigError}; + + #[derive(Debug, Clone)] + pub struct ResolvedProfile { + pub name: String, + pub block: crate::schema::ProfileBlock, + } + + pub fn parse(_source: &str) -> Result { + unimplemented!("Plan 05-02 Task 2 lands this") + } + + pub fn resolve_profile(_cfg: &ConfigFile, _name: &str) -> ResolvedProfile { + unimplemented!("Plan 05-02 Task 2 lands this") + } + ``` + Task 2 fills the bodies. This split keeps Task 1 a schema-only change for clean review. + + Step 6 — Un-ignore the 4 tests in `crates/vector-config/tests/schema_and_loader.rs` and fill them in. Remove the `#[ignore = "..."]` markers, populate bodies. Use the test scenarios listed in `` above. Example body for `parse_rejects_unknown_field`: + ```rust + #[test] + fn parse_rejects_unknown_field() { + let toml = "[default]\nbogus = 1\n"; + let err = vector_config::parse(toml).expect_err("unknown field must reject"); + assert!(err.message.contains("bogus"), "error message missing offending field: {}", err.message); + } + ``` + Note: tests fail until Task 2 lands the bodies — that's OK. We commit Task 1 + Task 2 together as one wave but the tests REMAIN in this task so Task 2's executor doesn't have to wonder where they live. Mark these tests with `#[ignore = "implemented in Task 2 of this plan"]` UNTIL Task 2 runs — Task 2 removes the ignore.

Receive from the channel; assert the received bytes form a valid xterm color reply (`b"\x1b]10;rgb:RRRR/GGGG/BBBB\x07"` shape — exact value depends on alacritty's default fg color, but the prefix `\x1b]10;` must be present). + + + Step 1 — Add `tokio` dep to `crates/vector-term/Cargo.toml` (if not already present): + ```toml + tokio = { workspace = true } + ``` + Verify by reading existing Cargo.toml — vector-term may already depend on tokio transitively or directly. + + Step 2 — Create `crates/vector-term/src/hyperlink.rs`: + ```rust + //!

If `alacritty_terminal::vte::ansi::ClipboardType` doesn't resolve, try `alacritty_terminal::ClipboardType` or `vte::ansi::ClipboardType`. Whichever works. + + Also: `Event::ClipboardLoad`'s second argument in alacritty 0.26 may be a `Box` callback. Pattern-match with `(_, _)` to ignore both; never invoke the callback (that would send a reply to the shell, which D-70 explicitly forbids). + + Step 4 — Update `crates/vector-term/src/term.rs` `Term::new` and the type signature wherever `NoopListener` was used. Replace the listener-type generic or stored field with `ForwardingListener`. **If `Term` is currently parameterized over `EventListener` via `alacritty_terminal::Term`, the public `Term::new` may need to accept `write_tx + clipboard_tx` channels as constructor args, OR ship a new `Term::with_listener(...)` constructor.** Recommendation: add `Term::with_channels(cols, rows, scroll, write_tx, clipboard_tx) -> Term` AND keep the old `Term::new(cols, rows, scroll) -> Term` using internal dummy channels (a `mpsc::channel(1)` whose receiver is dropped — equivalent to noop).
