**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).

**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.

**Success criteria**: encrypted DM round trip with the phone; DMs survive a watch app restart

**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).

**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`.
