+# CLAUDE.md — Project Rules for FareBot
+
+## Project Overview
+
+FareBot is a Kotlin Multiplatform (KMP) Android/iOS app for reading NFC transit cards. It is being ported from/aligned with [Metrodroid](https://github.com/metrodroid/metrodroid).
+
+**Metrodroid source code is in the `metrodroid/` directory in this repo.** Always use this local copy for comparisons and porting — do not fetch from GitHub.
+
+## Critical Rules
+
+### 1. NEVER lose existing features
+
+When refactoring, rewriting, or porting code: **every existing feature must be preserved**. Before modifying a file, understand what it currently does. After modifying it, verify nothing was lost. Do not silently drop functionality — if something must change, say so explicitly.
+
+Common regressions to watch for:
+- Missing UI elements (images, buttons, screens)
+- Lost navigation paths (menu items, long-press handlers)
+- Removed data fields from transit info display
+- Broken sample data loading
+
+### 2. No stubs — use serialonly for identification-only systems
+
+Do NOT create stub/skeleton transit implementations that only show a card name and serial number **when Metrodroid has a full implementation available to port**. If Metrodroid has trip parsing, balance reading, subscriptions, or other features for a system, port all of it — never reduce a full implementation to a stub.
+
+For systems where Metrodroid itself only supports identification (card name + serial number) with no further parsing, use `farebot-transit-serialonly/` — matching Metrodroid's `serialonly/` directory. These extend `SerialOnlyTransitInfo` and provide a `Reason` (LOCKED, NOT_STORED, MORE_RESEARCH_NEEDED) explaining why data isn't available.
+
+If a full implementation can't be ported yet (e.g., missing infrastructure framework), don't add the system at all until the dependency is ready.
+
+### 3. Faithful ports from Metrodroid
+
+When porting code from Metrodroid: **do a faithful port**. Do not simplify, abbreviate, or "improve" the logic. Port ALL features, ALL edge cases, ALL constants. After writing each file, diff it against the Metrodroid original to verify nothing was missed.
+
+- `ImmutableByteArray` → `ByteArray`
+- `Parcelize`/`Parcelable` → `kotlinx.serialization.Serializable`
+- `Localizer.localizeString(R.string.x)` → `stringResource.getString(Res.string.x)`
+- `Timestamp`/`TimestampFull`/`Daystamp` → `kotlinx.datetime.Instant`
+- `TransitData` → `TransitInfo`
+- `CardTransitFactory` → `TransitFactory<CardType, TransitInfoType>`
+
+Do NOT:
+- Skip features "for later"
+- Change logic unless there's a concrete reason
+- Remove constants, enums, or data that exist in the original
+- Simplify switch/when statements by dropping cases
+
+### 4. Debug systematically, not speculatively
+
+When something is broken: **add logging and diagnostics first**. Do not guess at fixes. The workflow should be:
+
+1. Add debug logging to understand what's actually happening
+2. Read the device console output
+3. Identify the root cause from actual data
+4. Fix the specific problem
+5. Remove debug logging
+
+Do NOT make speculative changes hoping they fix the issue. Each failed guess wastes a round.
+
+### 5. All code in commonMain unless it requires OS APIs
+
+Write all code in `src/commonMain/kotlin/`. Only use `androidMain` or `iosMain` for code that directly interfaces with platform APIs (NFC hardware, file system, UI system dialogs). No Objective-C. Tests use `kotlin.test`.
+
+### 6. Use StringResource for all user-facing strings
+
+All user-facing strings must go through Compose Multiplatform resources:
+- Define strings in `src/commonMain/composeResources/values/strings.xml`
+- For UI labels in `TransitInfo.getInfo()`, use `ListItem(Res.string.xxx, value)` or `HeaderListItem(Res.string.xxx)` directly
+- For dynamic string formatting, use `runBlocking { getString(Res.string.xxx) }`
+- Legacy pattern: Pass `StringResource` to factories — still works but not required for new code
+
+Example patterns:
+```kotlin
+// Preferred for static labels
+ListItem(Res.string.card_type, cardType)
+HeaderListItem(Res.string.card_details)
+
+// For dynamic values
+val formatted = runBlocking { getString(Res.string.balance_format) }
+```
+
+Do NOT hardcode English strings in Kotlin files.
+
+### 7. Use MDST for station lookups, not SQLite .db3
+
+Station databases should use the MDST (protobuf) format via `MdstStationLookup`, not SQLite .db3 files with SQLDelight. All MDST files live in `farebot-base/src/commonMain/composeResources/files/` and are accessed via `MdstStationLookup.getStation(dbName, stationId)`.
+
+Example:
+```kotlin
+val station = MdstStationLookup.getStation("orca", stationId)
+station?.stationName  // English name
+station?.companyName  // Operator name
+station?.latitude     // GPS coordinates (if available)
+```
+
+### 8. Verify your own work
+
+After making changes:
+- Run `./gradlew allTests` to confirm tests pass
+- Run `./gradlew assemble` to confirm the build succeeds
+- If you changed UI code, describe what the user should see
+- If you ported code, diff against the original source
+
+Do NOT claim work is complete without verification.
+
+### 9. Preserve context across sessions
+
+Key project state is in:
+- `/Users/eric/.claude/plans/` — implementation plans (check newest first)
+- `/Users/eric/Code/farebot/REMAINING-WORK.md` — tracked remaining work
+- Session transcripts in `/Users/eric/.claude/projects/-Users-eric-Code-farebot/`
+
+When continuing from a previous session, read these files to recover context rather than starting from scratch.
+
+## Build Commands
+
+```bash
+./gradlew allTests          # Run all tests
+./gradlew assemble          # Full build (Android + iOS frameworks)
+./gradlew :farebot-app-android:assembleDebug  # Android only
+```
+
+## Module Structure
+
+- `farebot-base/` — Core utilities, MDST reader, ByteArray extensions
+- `farebot-card-*/` — Card type implementations (classic, desfire, felica, ultralight, iso7816, cepas, vicinity)
+- `farebot-transit-*/` — Transit system implementations (one module per system)
+- `farebot-transit-serialonly/` — Identification-only systems (serial number + reason, matches Metrodroid's `serialonly/`)
+- `farebot-transit/` — Shared transit abstractions (Trip, Station, TransitInfo, TransitCurrency, etc.)
+- `farebot-app/` — KMP app framework (UI, ViewModels, DI, platform code)
+- `farebot-app-android/` — Android app shell (Activities, manifest, resources)
+- `farebot-app-ios/` — iOS app shell (Swift entry point, assets, config)
+
+## Registration Checklist for New Transit Modules
+
+1. Create `farebot-transit-{name}/build.gradle.kts`
+2. Add `include(":farebot-transit-{name}")` to `settings.gradle.kts`
+3. Add `api(project(":farebot-transit-{name}"))` to `farebot-app/build.gradle.kts`
+4. Register factory in `TransitFactoryRegistry.kt` (Android)
+5. Register factory in `MainViewController.kt` (iOS, non-Classic cards only)
+6. Add string resources in `composeResources/values/strings.xml`
+
+## Kotlin/Native Gotchas
+
+- `internal` types cannot be exposed in public APIs (stricter than JVM)
+- Constructor parameter names matter — use the exact names the data class defines
+- When removing a transitive dependency, add direct `api()` deps for anything that was accessed transitively

-# OV-chipkaart support for FareBot
-
-This contains the implementation of support for the OV-chipkaart used in the Netherlands.
-
-By [Wilbert Duijvenvoorde](https://github.com/wandcode)
-
-## Database
-
-The database is created with [ovc-tools][0], specifically my [fork][1] of it (nothing special just updated data and an option to discard machines data).
-
-## Keys
-
-To fully read an OV-chipkaart you will need the keys for all the sectors. These keys can be obtained with [mfocGUI][2] and can be found in the Keys folder after dumping. If you want to save some time, you could dump only the so called 'A' keys as those are the only ones that are used ;).
-
-## TODO / FIXME
-
-* Normally every trip has an end time (ExitTimeStamp) and it would be nice if it would be displayed. 
-* Most trips have a start and an end station, but some of the names are too long to display them (both) on the same line. Split them into two lines and maybe display the start or end time behind each one?
-* Display the subscriptions somewhere (its own tab or Advanced Info for example).
-* The whole keys part could use a serious rewrite...
-* Maybe move the database outside of the app to save space for those who don't need it?
-* See all the TODOs and FIXMEs throughout the code for everything that needs fixing.
-
-* (Not OV-chipkaart related and for the future): display public transit lanes on the Google map (if available)?
-
-## Thanks To
-
-* [PC Active][3] for hosting the [wiki][4].
-* [OV-Chipkaart Forum][5] for all the research and information.
-* [Huuf][2] for [mfocGUI][2].
-* [Nexus-s-ovc][6] which got me started.
-* [Eric Butler][7] for [FareBot][8] of course ;)

+# Flipper Dump TODO
+
+Card dumps serve two purposes:
+1. **Integration tests** — verify Metrodroid port correctness (full pipeline: dump → RawCard → Card → TransitInfo)
+2. **Sample cards in Explore tab** — tapping a card in the Explore tab loads a dump and shows parsed transit info
+
+Dumps live in `farebot-app/src/commonTest/resources/` (test) and will also be embedded as app resources for Explore tab samples.
+
+---
+
+## Already have dumps with integration tests
+
+### Samples + Tests (`farebot-app/src/commonTest/resources/` and `composeResources/files/samples/`)
+
+All cards below have both Explore screen samples and `SampleDumpIntegrationTest` coverage.
+
+**Data source key:**
+- **Real** = from an actual card scan (Flipper, Metrodroid export, or MFC binary)
+- **Synthetic** = hand-constructed from unit test data or code constants
+- **Needs scan** = a real Flipper/phone scan would improve the sample (more realistic data, actual trips/balances)
+
+| Card | Type | Format | Data source | Needs scan? | Test assertions |
+|------|------|--------|-------------|-------------|----------------|
+| Clipper | DESFire | Flipper | Real | No | 16 trips, $2.25 balance |
+| ORCA | DESFire | Flipper | Real | No | 0 trips, $26.25 balance |

+### Metrodroid test assets (reference only — `metrodroid/src/commonTest/assets/`)
+
+| Card | Type | Path | Notes |
+|------|------|------|-------|
+| Selecta | Classic | `selecta/selecta.json` | Vending machine, not transit |
+
+The `metrodroid/src/commonTest/assets/farebot/` directory has format-test dumps (Opal, CEPAS, FeliCa, Classic, Ultralight, DESFire) for testing import compatibility.
+
+The `metrodroid/src/commonTest/assets/parsed/` directory has expected *parse results* (not raw dumps): Rejsekort, Bilhete Unico, EasyCard, HSL v2, HSL UL, Opal, Troika UL, T-Money, CEPAS, Mobib, Holo, Selecta.

+
+## Dumps still needed — full implementations
+
+Cards with actual trip/balance/subscription parsing. These are the most valuable to get dump data for.
+
+### DESFire (Flipper can read directly)
+
+| Card | Module | Priority | Needs scan? | Notes |
+|------|--------|----------|-------------|-------|
+| **HSL v1** | `farebot-transit-hsl` | High | Yes — Flipper | Helsinki, old format APP_ID 0x1120ef. Full rewrite, no test coverage. |
+| **Waltti** | `farebot-transit-hsl` | High | Yes — Flipper | Oulu/Lahti/etc, APP_ID 0x10ab. Shares HSL module. |
+| **Tampere** | `farebot-transit-tampere` | High | Yes — Flipper | Shares HSL-family code. |
+| **Leap** | `farebot-transit-tfi-leap` | Medium | Yes — Flipper | Dublin, Ireland. EN1545-based. |
+| **Adelaide Metrocard** | `farebot-transit-adelaide` | Medium | Yes — Flipper | Adelaide, Australia. |
+| **Hafilat** | `farebot-transit-hafilat` | Low | Yes — Flipper | Abu Dhabi. |
+
+### Mifare Classic — no keys needed (Flipper can read directly)
+
+These Classic cards don't use encrypted sectors for their transit data, so Flipper can read them like any other card.
+
+| Card | Module | Needs scan? | Notes |
+|------|--------|-------------|-------|
+| **Bip** | `farebot-transit-bip` | Yes — Flipper | Santiago, Chile. |
+| **Bonobus** | `farebot-transit-bonobus` | Yes — Flipper | Cadiz, Spain. |
+| **Ricaricami** | `farebot-transit-ricaricami` | Yes — Flipper | Milan, Italy. |

+| **Kyiv Metro** | `farebot-transit-kiev` | Yes — Flipper | Kyiv, Ukraine. |
+| **Kyiv Digital** | `farebot-transit-kiev` | Yes — Flipper | Kyiv, Ukraine. Variant. |
+| **Metro Q** | `farebot-transit-metroq` | Yes — Flipper | Qatar. |
+| **Gautrain** | `farebot-transit-gautrain` | Yes — Flipper | Gauteng, South Africa. |
+| **Touch n Go** | `farebot-transit-touchngo` | Yes — Flipper | Malaysia. |
+| **KomuterLink** | `farebot-transit-komuterlink` | Yes — Flipper | Malaysia. |

+| **Otago GoCard** | `farebot-transit-otago` | Yes — Flipper | Otago, NZ. |
+| **Tartu Bus** | `farebot-transit-pilet` | Yes — Flipper | Tartu, Estonia. |
+| **YarGor** | `farebot-transit-yargor` | Yes — Flipper | Yaroslavl, Russia. |
+
+### Mifare Classic — keys required (Flipper needs key dictionary)
+
+These cards encrypt their transit sectors. Flipper can crack some keys with `mfkey32` or use a known dictionary, but it's more effort.
+
+**Note on Charlie Card:** `check()` uses salted MD5 key hashes. Our JSON/Flipper parsers don't currently extract keys from the trailer block, so `DataClassicSector.keyA`/`keyB` are always null. Fix: either add key extraction to `RawClassicSector.parse()` (reads bytes 0-5 and 10-15 from trailer block), or add explicit key fields to the JSON format. Once fixed, a Flipper scan with MBTA keys (publicly documented) would work.
+
+| Card | Module | Needs scan? | Notes |
+|------|--------|-------------|-------|
+| **OV-chipkaart** | `farebot-transit-ovc` | Yes — Flipper + keys | Full EN1545 rewrite, trip dedup, subscriptions, autocharge. 4K card. |

+| **Kazan** | `farebot-transit-kazan` | Yes — Flipper + keys | Kazan, Russia. |
+| **Christchurch Metrocard** | `farebot-transit-chc-metrocard` | Yes — Flipper + keys | Christchurch, NZ. |
+
+### FeliCa (Flipper can read directly)

+|------|--------|----------|-------------|-------|
+| **OV-chipkaart UL** | `farebot-transit-ovc` | High | Yes — Flipper | Dutch disposable. Part of OVC rewrite. |
+
+### ISO7816 / Calypso (Flipper CANNOT read — need Android NFC dump)
+
+Flipper Zero does not support ISO 14443-4 / ISO 7816 protocol reads. These require an Android phone running FareBot/Metrodroid to capture the dump, then export as JSON.
+
+| Card | Module | Priority | Needs scan? | Notes |

+| **NETS FlashPay** | `farebot-transit-ezlink` | Medium | Yes — Android phone | Singapore. Shares EZ-Link module. |
+
+---
+
+## Dumps still needed — serial-only and preview (low priority)
+
+These cards only show a card name and serial number (no trip/balance parsing), or are `preview = true` (keysRequired, not fully functional). A dump is nice for Explore screen completeness but doesn't exercise much parsing logic.
+
+### Serial-only (identification only)
+
+| Card | Type | Module | Needs scan? | Notes |
+|------|------|--------|-------------|-------|
+| Nol | DESFire | serialonly | Yes — Flipper | Dubai, UAE. |

+## Summary
+
+| Category | Have (with tests) | Synthetic (need real scan) | On GitHub (not downloaded) | Need scan: no keys | Need scan: keys required | Need scan: serial/preview |
+|----------|------------------|---------------------------|---------------------------|--------------------|--------------------------|---------------------------|
+| DESFire | 8 | 2 (Myki, TriMet Hop) | 0 | 6 | — | 5 |
+| Classic (no keys) | 7 | 4 (SEQ Go, LAX TAP, MSP GoTo, Bilhete Unico) | 1 (Zaragoza) | 14 | — | 2 serial |
+| Classic (keys) | — | — | — | — | 8 | ~18 preview |
+| FeliCa | 4 | 1 (Octopus) | 0 | 2 | — | 7 Suica variants |
+| Ultralight | 4 | 1 (Compass) | 2 (Venezia UL, Andante) | 1 | — | 0 |
+| ISO7816 | 2 | 0 | 2 (Riga, Mexico City) | 12 | — | 8 |
+| CEPAS | 1 | 0 | 0 | 1 | — | 0 |
+| **Total** | **23** (15 real + 8 synthetic) | **8** | **5** | **36 easy** | **8 need keys** | **~40 low-pri** |
+
+† Synthetic dump — works for tests but a real Flipper/phone scan would provide more realistic data.
+\* Troika Classic has programmatic test data only (not a sample file).
+
+## Dump format notes
+
+- **Flipper `.nfc`** — Flipper Zero native format. Supported for DESFire, Classic, FeliCa, Ultralight.
+- **`.mfc`** — Raw Mifare Classic binary dump (1K = 1024 bytes, 4K = 4096 bytes).
+- **FareBot/Metrodroid JSON** — Exported from Android app. Required for ISO7816/CEPAS cards that Flipper can't read.
+- All formats are supported by `CardImporter` / `FlipperNfcParser`.
+
+## Known issues
+
+### Classic card key extraction
+Our JSON and Flipper parsers don't extract keyA/keyB from the MIFARE Classic trailer block when parsing. This means `DataClassicSector.keyA` and `keyB` are always null. Cards that use `checkKeyHash()` for detection (e.g., Charlie Card) won't work with dumps until this is fixed.
+
+**Fix:** In `RawClassicSector.parse()`, detect the trailer block (last block of the sector) and extract bytes 0-5 as keyA and bytes 10-15 as keyB, then pass to `DataClassicSector.create()`.

-##  Gradle start up script for UN*X
-##
+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
