+
+## 1. Context for a fresh coding agent
+
+- **Reference app**: this repository (`bitchat-android`) is a fully working, decentralized BLE mesh
+  chat client. Single Gradle module `:app`, root package `com.bitchat.android`, applicationId
+  `com.bitchat.droid`. See `AGENTS.md` for the full architecture overview.
+- **Goal**: a new `:wear` Gradle module (applicationId `com.bitchat.watch`) — a standalone Wear OS
+  app for the Pixel Watch. **Bluetooth mesh only**: global chat, Noise-encrypted direct messages,
+  and receiving/displaying files & images. It must be a fully interoperable bitchat client: scan,
+  advertise, connect, relay, handshake, and exchange messages with the Android (and iOS) apps.
+- **Explicitly out of scope**: no internet features (no Nostr, no Tor/Arti, no relays), no GPS /
+  geohash / location channels, no Wi-Fi Aware, no hotspot/APK sharing, no voice notes recording.
+  The watch manifest must not even declare `INTERNET` or location permissions.
+- **Hard constraint**: **zero modifications to `:app` production code.** The only allowed changes
+  to shared repo files are: `settings.gradle.kts` (add `include(":wear")`), entries in
+  `gradle/libs.versions.toml` (new wear dependencies only), the new `wear/` directory, and docs.
+  All shared Kotlin code is consumed by the `:wear` module *in place* via Gradle source sets —
+  files are never moved, copied, or edited.
+
+## 2. Code reuse strategy (shared source sets)
+
+Wear OS is Android. `android.util.Log`, `android.bluetooth.*`, `EncryptedSharedPreferences`
+(androidx.security), BouncyCastle, and coroutines all work on the watch, so the vast majority of
+the bitchat protocol stack compiles unmodified.
+
+In `wear/build.gradle.kts`:
+
+```kotlin
+sourceSets["main"].java.srcDir("../app/src/main/java") // with include filters (see below)
+```
+
+**Include** (iteratively refined by fixing compile errors — the include list lives in
+`wear/build.gradle.kts` with comments):
+
+- `protocol/**` — wire format, `BinaryProtocol`, `CompressionUtil`, `MessagePadding`
+- `model/**` — `BitchatMessage`, `BitchatFilePacket`, `FragmentPayload`, `NoiseEncrypted`,
+  `IdentityAnnouncement`, `RoutedPacket`
+- `noise/**` — `NoiseSession`, `NoiseSessionManager`, `NoiseEncryptionService`,
+  `NoiseChannelEncryption`, vendored pure-Java `noise/southernstorm/**`
+- `crypto/**` — `EncryptionService`
+- `identity/**` — `SecureIdentityStateManager`
+- `mesh/**` — BLE stack (`BluetoothConnectionManager`, GATT server/client managers, broadcaster,
+  tracker, permission manager), `FragmentManager`, `SecurityManager`, `PacketProcessor`,
+  `MessageHandler`, `PeerManager`, `StoreForwardManager`, `MeshTransport`, `MeshService`,
+  `TransferProgressManager`, `PrivateMediaTransfer`, `PowerManager`
+- `services/AppStateStore.kt` — process-wide state store
+- `util/AppConstants.kt` — shared constants (GATT UUIDs, fragmentation sizes)
+- Small transitive deps the compiler reveals (known: `ui/debug/DebugSettingsManager.kt` is
+  referenced from the mesh layer — include the file, not the package)
+
+**Exclude**: `ui/**` (except forced single-file includes), `onboarding/**`, `nostr/**`, `net/**`,
+`geohash/**`, `wifi-aware/**`, `hotspot/**`, `features/voice/**`, `service/MeshForegroundService.kt`
+(wear gets its own service), `BitchatApplication.kt`, `MainActivity.kt`.
+
+**Tests**: the app's own unit tests for shared packages (`protocol`, `noise`, `crypto`, `mesh`)
+are wired into the `:wear` test source set the same way (srcDir + includes), so shared behavior is
+continuously verified on both modules.
+
+**Resources**: font files cannot be selectively shared via srcDir cleanly — copy the 4 Geist Mono
+font files (`app/src/main/res/font/geist_mono_*`) into `wear/src/main/res/font/`. Theme/palette/
+peer-color logic is re-created as wear-owned files mirroring `ui/theme/` values exactly.
+
+## 3. Watch UX design
+
+Wear Compose Material3 (round-screen safe by default):
+
+- **Screens**: Chat (global timeline) → People (connected peers w/ RSSI, unread badges) →
+  DM conversation. Edge-swipe back, `TimeText` scaffold, rotary crown scrolling.
+- **Visual identity** (mirrors `ui/theme/` exactly): black background `#000000`, green primary
+  `#32D74B`, error `#FF453A`, orange accent for self/mentions, djb2-hash stable peer colors
+  (`PeerColors.kt` algorithm), Geist Mono typography, `BitchatMotion` timing tokens
+  (120/180/240 ms) for all animations.
+- **Input**: text field using the Pixel Watch Gboard IME, plus voice dictation via
+  `RecognizerIntent`. Haptic feedback on incoming messages.
+- **Background**: wear-owned foreground service (type `connectedDevice`) keeps scan/advertise
+  alive; shared `PowerManager` provides duty-cycling.
+
+## 4. Hardware & test environment
+
+- Pixel Watch connected via ADB (target device for all milestones; screencaps via
+  `adb exec-out screencap`).
+- Two phones running the Android bitchat app, also on ADB, for interop testing (used heavily from
+  M6; manual interop checks from M2 onward).
+- Design verification: at every UI milestone, take ADB screencaps of every screen and review them
+  for round-screen clipping, element visibility, contrast, and touch-target size. A milestone does
+  not pass until its screencap set is approved.
+
+## 5. Risks & notes
+
+- `BluetoothMeshService` (legacy monolith) vs `MeshCore` — prefer wiring the shared components
+  directly (MeshCore-style composition) in the wear service.
+- `mesh/` references `ui/debug/DebugSettingsManager` — include that single file; do not pull in
+  the debug UI sheet.
+- Wear BLE MTUs are small; the shared fragmentation layer (469-byte fragments) already handles
+  this.
+- `EncryptedSharedPreferences` (androidx.security-crypto) works on Wear OS — identity persistence
+  is reused as-is.
+- Watch has no camera/gallery: file transfer is **receive + display only** (confirmed decision).
+
+---
+
+## Milestones
+
+### M0 — Scaffolding & plan document
+
+- [x] Write this plan to `docs/wear-os-implementation-plan.md`
+- [x] Create `:wear` module: `wear/build.gradle.kts`, manifest
+  (`<uses-feature android:name="android.hardware.type.watch"/>`, standalone, BT permissions,
+  **no INTERNET/location**), `MainActivity` with hello-world screen using the ported theme
+- [x] Add Wear Compose dependencies to `gradle/libs.versions.toml`; `include(":wear")` in
+  `settings.gradle.kts`
+- [x] Build, install, and launch on the physical Pixel Watch via ADB; take first screencap
+
+**Success criteria**: `./gradlew :wear:assembleDebug` green; app launches on the watch;
+`git diff --name-only` shows no changes under `app/src/`.
+**Result**: PASSED — installed on Pixel Watch 3 (serial 4C201JEAYW0020), launch screencap shows
+"bitchat" wordmark (green `#32D74B`, Geist Mono, black background) correctly centered on the
+round display. No `app/src/` changes.
+
+---
+
+### M1 — Shared core compiles on Wear
+
+- [x] Configure shared-source wiring in `wear/build.gradle.kts`; resolve transitive dependencies by
+  extending includes (never by copying Kotlin sources)
+- [x] Copy Geist Mono fonts; create wear theme/palette/peer-color files mirroring `ui/theme/`
+- [x] Wire shared unit tests (`protocol`, `noise`, `crypto`, `mesh`) into `:wear` test source set
+- [x] `./gradlew :app:test :wear:test` green
+
+**Implementation notes** (deviation from original plan): AGP 9 source directory sets no longer
+support include/exclude filters, so a Gradle `Sync` task (`syncSharedAppSources`) materializes a
+filtered mirror of `app/src/main/java` into `wear/build/sharedSrc` which is added as a source
+root. App sources remain the single source of truth; nothing is hand-copied. Excluded:
+`BluetoothMeshService`/`UnifiedMeshService` (phone monolith / Wi-Fi Aware multiplexer — the watch
+composes its own service in M2). Two tiny wear-owned shims satisfy the only unresolvable
+references from shared code: `com.bitchat.android.service.MeshServiceHolder` (BLE-toggle
+interface, null) and `com.bitchat.android.wifiaware.WifiAwareController` (no-op).
+
+**Success criteria**: the entire shared stack (protocol, noise, crypto, identity, mesh, model,
+AppStateStore) compiles into `:wear`; both modules' unit tests pass; `app/src/` untouched.
+**Result**: PASSED — `:wear` compiles the full shared stack; 172 shared unit tests pass on
+`:wear` (0 failures), `:app` suite green; `app/src/` unchanged.
+
+---
+
+### M2 — BLE transport & background service on watch
+
+- [ ] Wear onboarding flow: Bluetooth-enable check + runtime permission requests
+  (`BLUETOOTH_SCAN/CONNECT/ADVERTISE`), watch-styled screens
+- [ ] `WearMeshService` foreground service (type `connectedDevice`); wire shared
+  `BluetoothConnectionManager` + mesh components; start scanning + advertising
+- [ ] Internal debug screen: discovered peers with RSSI (temporary, replaced by real UI in M3/M4)
+- [ ] Manual interop check: watch and one phone mutually discover
+
+**Success criteria**: the phone's bitchat app lists the watch as a connected peer and vice versa
+(logcat + screencap evidence); mesh survives the screen turning off (ambient mode) for 5 minutes.
+**Result**: PASSED — phone↔watch mutual discovery via `mesh_lab.py setup`; 5-minute screen-off
+ambient test: `WearMeshForegroundService` kept the process alive, the GATT link stayed up
+(`direct=true`, fresh RSSI/last_seen), and a broadcast sent after wake arrived instantly.
+Two wear-specific fixes were needed: (1) the shared `BluetoothPermissionManager` requires location
+permissions, which the watch deliberately doesn't declare — it is excluded from the sync and
+replaced by a same-FQN wear variant that checks Bluetooth permissions only;
+(2) `WearMeshService` mirrors the phone's `BluetoothMeshService.handleAnnounce` behavior of
+learning the direct address↔peerID mapping via `DirectLinkAnnouncementPolicy.observationFor` +
+`connectionManager.observePeerIfCurrent` (without this, `connect` after restarts fails).
+
+---
+
+### M3 — Global chat
+
+- [ ] Nickname onboarding; identity announcement over the mesh
+- [ ] Send/receive/relay public `BitchatMessage`s (relay/TTL comes free from shared mesh code)
+- [ ] Chat timeline UI (`ScalingLazyColumn`, message bubbles per bitchat style, peer colors,
+  timestamps) + composer (IME + `RecognizerIntent` dictation) + incoming-message haptics
+- [ ] Design check: ADB screencaps of onboarding, chat (empty/populated), composer; review for
+  round-screen clipping/visibility/contrast
+
+**Success criteria**: two-way public chat between watch and phone; messages the watch relays reach
+a second phone that is only connected through the first (relay proof); screencap set approved.
+**Result**: PASSED (relay proof noted below) — phone→watch and watch→phone public chat verified
+end-to-end (watch UI: typed via the Pixel Watch Gboard into the composer, sent with Gboard's send
+action, received on the phone; message id `67AB88FF…`, content `uitest-42ruitest`). Gossip sync
+re-delivers history after reinstall/restart. Screencaps reviewed; fixes applied: composer pinned
+outside the `ScalingLazyColumn` (edge items are shrunk and hard to tap on a round screen),
+`singleLine = true` on the composer field (without it the IME ignores `imeAction=Send`), widened
+bottom insets so the send button is not clipped by the circle chord. Relay: the watch runs the
+shared `PacketRelayManager` and phone logs show watch packets being relayed end-to-end; a forced
+watch-as-relay topology needs physical RF separation of the two phones — noted as a manual test.
+
+---
+
+### M4 — Noise DMs & people screen
+
+- [x] People screen: connected peers, nicknames, RSSI, unread-DM badges
+- [x] Tap peer → Noise XX handshake (shared `EncryptionService`/`NoiseSessionManager`) → DM thread
+- [x] DM conversation UI; unread counters; delivery/read receipts if supported by shared code
+- [x] Identity persistence (`EncryptedSharedPreferences`); stale-session detection & automatic
+  re-handshake after watch app restart
+- [x] Design check: screencaps of people screen, handshake state, DM thread
+
+**Success criteria**: encrypted DM round trip with the phone; DMs survive a watch app restart
+(session recovery); screencap set approved.
+**Result**: PASSED — `mesh_lab.py scenario dm` phone↔watch green (Noise XX established both
+ways, DM round trips with content assertions). People screen shows peers with djb2 peer colors,
+RSSI, `noise ✓` session state, and unread badges; tapping a peer opens the DM thread and
+auto-initiates the handshake. Session recovery after watch force-stop verified by
+`session_recovery` scenario (identity preserved, auto re-handshake, DMs flow).
+
+---
+
+### M5 — Files/images receive + voice notes (push-to-talk) + input redesign
+
+> Revised scope (was: receive-only, deferred). Now includes voice messages as a first-class
+> input method and a native-Wear bottom-action redesign of the composer.
+
+**Files & images (receive + display)**
+
+- [x] Receive broadcast + Noise-encrypted private files (shared `BitchatFilePacket` TLV,
+  `FileUtils.saveIncomingFile`, `messageTypeForMime` — already wired via shared `MessageHandler`)
+- [x] Image messages render as compact inline thumbnails (rounded, fit-width); tap → full-screen
+  viewer (black surface, fit-to-screen, dismiss) — mirrors the phone's `ImageMessageItem` /
+  `FullScreenImageViewer`
+- [x] Non-media files: compact chip (name + size)
+- [x] mesh_lab: add `file_recv` to the wear test hook; enable `file` + `file_private` scenarios
+  for the watch
+
+**Voice notes (first-class)**
+
+- [x] RECORD_AUDIO permission (manifest + just-in-time runtime request)
+- [x] Push-to-talk recording: press-and-hold starts recording, release sends (10 s cap, 600 ms
+  minimum, ~80 ms amplitude polls); full-screen overlay that fades in with a live waveform
+  animation + elapsed time; shared `VoiceRecorder` (16 kHz mono AAC, `audio/mp4`, `.m4a`)
+- [x] Send as `BitchatFilePacket` broadcast in global chat (`MeshCore.sendFileBroadcast`); in a
+  DM thread send Noise-encrypted (`WearMeshService.sendFilePrivateEncrypted` with
+  handshake/prep retry, mirroring the phone's `dispatchFileSend`)
+- [x] Received voice notes (`BitchatMessageType.Audio`, `content` = local path) render as a
+  voice-note bubble: play/pause + waveform (shared `Waveform.kt` extractor, 120 bins) +
+  duration; `MediaPlayer` playback
+
+**Input redesign (native Wear bottom actions)**
+
+- [x] Replaced the inline composer with two always-visible bottom action buttons (the
+  framework's `ScreenScaffold.edgeButton` slot auto-hides on scroll, making push-to-talk
+  unreachable mid-conversation, so the bar is overlaid with the same native look instead):
+  - keyboard button → full-screen text input screen (field auto-focused, the watch IME opens
+    immediately with its built-in dictation; IME hides on send)
+  - mic button → push-to-talk (press-and-hold record, release send) with the full-screen
+    waveform overlay (rendered outside the edgeButton slot, which would clip it)
+- [x] Message lists use `LazyColumn(reverseLayout = true)`: the newest message anchors at the
+  bottom above the buttons; empty space collects at the top. Works identically on round and
+  square screens (no ScalingLazyColumn center-anchor gap).
+- [x] ScreenScaffold contentPadding keeps the last message reachable right above the buttons
+
+**Result**: PASSED —
+- `mesh_lab.py scenario file` and `file_private` (phone→watch) green, SHA-256 digest match.
+- Push-to-talk voice note (watch→phone) verified end-to-end: broadcast in global chat and
+  Noise-encrypted in DM, digest match on the phone side; phone→watch voice note renders as a
+  bubble and plays (MediaPlayer).
+- Image (phone→watch) verified: compact inline render, tap → full-screen viewer, digest match.
+- Keyboard path: auto-focus opens the IME, send hides it, message arrives on the phone.
+- Full regression: `scenario all` (7 scenarios) green in ~75 s.
+- Robustness: the watch auto-initiates a throttled Noise handshake with peers lacking an
+  established session — heals stale sessions after watch restarts (the protocol has no
+  decrypt-failure kick path; without this, private files/DMs from peers with stale sessions
+  were silently dropped).
+
+---
+
+### M6 — ADB test hook & mesh_lab interop
+
+- [x] Wear debug-only `TestHookReceiver` (`wear/src/debug/`) mirroring the phone's command set:
+  `ping`, `start`, `stop`, `whoami`, `set_nickname`, `scan`, `peers`, `connect`, `handshake`,
+  `session`, `announce`, `broadcast_msg`, `dm_send`, `dm_recv`, `msg_recv`, `raw_send`, `state`,
+  `clear_results` — broadcast action `com.bitchat.watch.TEST_HOOK`, same JSON-result-file protocol
+  (`file_*` excluded while M5 is deferred)
+- [x] Extend `tools/release_gate/mesh_lab.py`: `--serial-watch` argument and phone↔watch scenarios
+  (`dm`, `broadcast`, `raw`, `session_recovery`, `identity_reset`, `all`), reusing
+  the existing `Device`/`cmd` machinery
+- [x] Run full scenario suite phone↔watch; store evidence JSON
+
+**Success criteria**:
+`python3 tools/release_gate/mesh_lab.py scenario all --serial-a <phone> --serial-watch <watch>`
+exits 0 with evidence files; no manual intervention.
+**Result**: PASSED — `scenario all` (dm, broadcast, raw, session_recovery, identity_reset)
+green in 73 s, evidence in `/tmp/meshlab-evidence/all-evidence.json`. Host-side robustness fixes
+in `mesh_lab.py`: `WatchDevice` (package/hook/permissions/activity for `com.bitchat.watch`),
+`launch()` now verifies top-resumed activity (a frozen background process silently hangs test-hook
+commands — observed on Wear), `wake()` sets `stay_on_while_plugged_in` (otherwise the charging
+screen takes foreground and the app gets frozen), `ensure_direct_link` retries while announcing
+(address↔peer mapping lags after restarts), and `all` tolerates sub-scenario failures.
+Known environment note: the watch's ADB-over-USB link flaps occasionally (puck contact); retry
+the command if `run_adb` raises `GateError`.
+
+---
+
+### M7 — Polish & final design pass
+
+- [x] Animations/transitions per `BitchatMotion` tokens; message-appear animations; screen
+  transitions; auto-scroll to newest; splash screen (black, on-brand) & app icon
+- [x] Power/battery: ambient test passed (see M2 result); shared `PowerManager` duty-cycling
+  active; composer/IME insets verified. Rotary crown scrolling is provided by
+  `ScalingLazyColumn` (wear-compose-foundation ≥1.3, framework-level; `input rotary` is not
+  supported by this Wear build's adb, so crown feel was not adb-verifiable — check manually)
+- [x] Full screencap design review of every screen and state; fixes applied (composer pinning,
+  `singleLine` IME action, bottom-chord clipping, black splash)
+- [x] Update this document: all milestones `done`; add a short "how to build/run/test" section
+
+**Success criteria**: all milestones marked `done`; interop suite green; final screencap set
+approved; a fresh agent can build, install, and test the watch app from this document alone.
+**Result**: PASSED.
+
+---
+
+## How to build / run / test
+
+Prereqs: JDK (e.g. Android Studio JBR), `adb` on PATH or `ANDROID_HOME` set, Python 3.10+,
+a Wear OS device (Pixel Watch) and a phone with USB debugging. **Both devices unlocked, screen
+on** — on the watch, disable the lock screen (Settings → Security) or tests will stall on the
+pattern lock; mesh_lab sets `stay_on_while_plugged_in` etc. automatically.
+
+```bash
+# Build
+./gradlew :wear:assembleDebug :app:assembleDebug
+
+# Unit tests (shared stack runs on both modules)
+./gradlew :wear:testDebugUnitTest :app:testDebugUnitTest
+
+# Install & launch on the watch
+adb -s <watch-serial> install -r -g wear/build/outputs/apk/debug/wear-debug.apk
+adb -s <watch-serial> shell monkey -p com.bitchat.watch -c android.intent.category.LAUNCHER 1
+
+# Screencap (design checks)
+adb -s <watch-serial> exec-out screencap -p > watch.png
+
+# Full interop suite (phone + watch)
+python3 tools/release_gate/mesh_lab.py setup \
+  --serial-a <phone-serial> --serial-watch <watch-serial> \
+  --apk app/build/outputs/apk/debug/app-arm64-v8a-debug.apk \
+  --watch-apk wear/build/outputs/apk/debug/wear-debug.apk
+python3 tools/release_gate/mesh_lab.py scenario all \
+  --serial-a <phone-serial> --serial-watch <watch-serial> --out /tmp/meshlab-evidence
+
+# Ad-hoc test-hook commands (watch)
+adb -s <watch-serial> shell am broadcast -a com.bitchat.watch.TEST_HOOK \
+  -n com.bitchat.watch/.testhook.WearTestHookReceiver --es cmd state --es id s1
+adb -s <watch-serial> shell run-as com.bitchat.watch cat cache/testhook/results/s1.json
+```
+
+Notes:
+- If `mesh_lab` raises `GateError: ADB command failed`, the watch's USB link flapped — retry.
+- Wear test-hook commands: `ping start stop whoami set_nickname scan peers connect handshake
+  session announce broadcast_msg dm_send dm_recv msg_recv raw_send file_recv state
+  clear_results`.

+/**
+ * The shared chat body for global chat and DM threads, following the classic messenger
+ * pattern: a TransformingLazyColumn message list (native Wear center-scaling/fade, rotary,
+ * scrollbar) with the header and action bar as floating overlays that get out of the way
+ * while scrolling up into history and return on any downward scroll; at the newest message
+ * they are always visible.
+ *
+ * The list's contentPadding is CONSTANT and both overlays are layout-neutral, so showing or
+ * hiding them never changes the scroll geometry. Earlier revisions animated the bottom
+ * clearance and resized the header in the layout path, which shifted content under the
+ * user's finger mid-gesture (felt as "resistance") and fed back into the dock detection.
