Bluetooth: wire existing AudioRouteManager SCO support through both app
variants. Replace binary speaker toggle with 3-way route cycling
(Earpiece → Speaker → Bluetooth). Tauri side adds JNI bridge functions
(start/stop/query SCO, device availability) and Oboe stream restart.
Network awareness: integrate Android ConnectivityManager to detect
WiFi/cellular transitions and feed them to AdaptiveQualityController
via lock-free AtomicU8 signaling. Enables proactive quality downgrade
and FEC boost on network handoffs.
Build: add --arch flag to build-tauri-android.sh supporting arm64,
armv7, or all (separate per-arch APKs for smaller tester binaries).

Pre-existing build breakage on feat/desktop-audio-rewrite @ 8ceb6f4 —
TextAlign was imported twice (line 5 and line 50), causing Kotlin
compilation to fail with:
e: InCallScreen.kt:5:39 Conflicting import, imported name 'TextAlign' is ambiguous
e: InCallScreen.kt:50:39 Conflicting import, imported name 'TextAlign' is ambiguous
The line-5 copy was squeezed into the middle of the foundation.* block
(alphabetically out of place) — an accidental extra paste. The line-50
copy sits in the correct alphabetical position. Removed the former.
This blocks the APK build for the opus-DRED-v2 rebase. Unrelated to DRED
itself but the error surfaced because the cherry-picked phases caused
a clean Gradle build (no UP-TO-DATE short-circuit) that re-compiled
InCallScreen.kt against the fresh class graph.
Also noting that the previous working APK (unridden-alfonso.apk) was
built from the stale d0c1731 baseline which didn't have this bug —
one more reason the stale-branch build problem went unnoticed until
the opus-DRED-v2 rebase forced a clean Gradle pass.

- Mode toggle: "Room" vs "Direct Call" tabs on pre-connection screen
- Direct Call mode: Register button → registers on relay signal channel
- After registration: shows fingerprint dial pad + incoming call panel
- Incoming call: green Accept / red Reject buttons with caller info
- Ringing state display while waiting for callee
- CallSetup auto-connects to media room
- CallStats extended: sas_code, incoming_call_id/fp/alias fields
- CallViewModel: registerForCalls(), placeDirectCall(), answerIncomingCall()

- Android default room changed from 'android' to 'general'
- Relay choose_profile capped at GOOD (Opus 24k) — studio tiers
(32k/48k/64k) cause high packet loss on federation paths due to
larger datagrams exceeding path MTU. Will re-enable after MTU
discovery is implemented.

Participants now grouped by relay on Android:
- Green dot + "THIS RELAY" for local participants
- Blue dot + relay label for federated participants
Added relayLabel to RoomMember data class, parsed from
relay_label JSON field. UI groups and renders with headers.

Wire AdaptiveQualityController into Android engine for auto codec
switching based on network quality reports. Add color-coded TX/RX
codec badges to the in-call screen showing active codecs and Auto mode.
- Recv task: ingest QualityReports, feed to controller, signal profile
changes via AtomicU8 to send task
- Send task: check for pending profile switch at frame boundaries,
update encoder/FEC/frame size
- Track peer codec from incoming packet headers
- Kotlin UI: codec badges (blue=studio, green=good, amber=degraded,
red=catastrophic) with Auto tag
- Add .taskmaster to .gitignore

1. Auto codec: new "Auto" position on quality slider (JNI index 7).
When selected, the engine uses the relay's chosen_profile from
CallAnswer instead of the local preference. Slider now has 8
positions: Studio 64k → Auto → Codec2 1.2k.
2. Force ping: added refresh button (↻) in Manage Relays dialog
header. Calls pingAllServers() to re-check all relays on demand.
3. Delete relay fix: the X button was inside a Surface(onClick=...)
which swallowed the touch event. Replaced with a separate Surface
that properly intercepts the click.

1. Wire protocol: add Opus 32k/48k/64k (CodecId 6/7/8) + STUDIO
profiles with is_opus() helper. Opus enc/dec accept all Opus variants.
2. JNI bridge: expand profile_from_int to 7 levels (0-6) mapping to
GOOD, DEGRADED, CATASTROPHIC, Codec2_3200, STUDIO_32K/48K/64K.
3. Settings UI: replace radio buttons with Material3 Slider — 7 stops
from Studio 64k (green) to Codec2 1.2k (dark red), matching desktop.
4. Key-change warning: AlertDialog on connect when server fingerprint
has changed. Shows old vs new fingerprint, Accept New Key or Cancel.
Accepting saves the new fingerprint and proceeds with the call.
5. Engine recv: handle studio codec IDs in auto-switch path.

Ping was a static JNI method that loaded the .so before nativeInit,
crashing jemalloc. Now ping is an instance method on WzpEngine:
- Engine is created once (nativeInit), reused for both ping and call
- pingRelay() uses same tokio runtime pattern as startCall()
- Auto-pings all servers on app launch (after engine init)
- No process restart needed
- TOFU fingerprints saved on first successful ping
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Ping button: pings all servers via native QUIC, saves RTT + fingerprint
to SharedPreferences, then exits process (System.exit)
- On restart: loads saved ping results (no native .so loading needed)
- Avoids jemalloc crash: native lib only loaded once per process lifetime
- Removed broken UDP probe (QUIC servers don't respond to it)
- SettingsRepository: savePingRtt/loadPingRtt for cached results
- PingResult: added reachable field
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- AudioPipeline.debugRecording defaults to false (was true)
- SettingsRepository: persist debug_recording preference
- CallViewModel: debugRecording StateFlow + setter, wired to AudioPipeline
- Only records PCM + RMS when explicitly enabled in settings

Replace WzpEngine.pingRelay() (JNI, loads native .so, crashes jemalloc
on Android 16 MTE) with pure Kotlin DatagramSocket UDP probe.
- RelayPinger: sends QUIC Version Negotiation trigger packet, measures
RTT from response. No native lib, no JNI, zero crash risk.
- Periodic: pings all servers every 5 seconds via coroutine
- Server fingerprint: filled lazily on first real QUIC connection
(TOFU still works, just delayed)
- Lock status: OFFLINE when ping fails, NEW until first connection

Backport from desktop client to Android:
Identicons:
- New Identicon.kt composable: deterministic 5x5 symmetric Canvas pattern
from fingerprint hash (same algorithm as desktop identicon.ts)
- Participant list shows identicon + name + tappable fingerprint
- Settings page shows identicon next to fingerprint
CopyableFingerprint:
- Tap any fingerprint text to copy to clipboard with Toast feedback
- Used in participant list and settings page
Recent rooms:
- SettingsRepository: persists last 5 (relay, room) pairs
- CallViewModel: saves on startCall, exposes as StateFlow
- InCallScreen: clickable chips that fill room + select matching server
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Root cause: send_media() returns Err(Blocked) when QUIC congestion
window is full. The send task treated ANY send error as fatal (break),
killing the entire call. Now send errors drop the packet and continue.
Also hardened recv task to survive transient errors and added health
logging (recv gap tracking, periodic stats) to both send and recv.
Relay: added comprehensive debug logging — recv gaps, lock contention,
forward latency, send errors — all per-participant with 5s stats.
Other changes:
- AEC toggle in Settings (persisted, applied on next call)
- Debug report: records call audio (WAV), RMS histogram (CSV), logcat,
stats. Emailed as zip via Android share intent after call ends.
- Replaced LinearProgressIndicator with Box (compose version compat)
- FileProvider for sharing debug zip attachments

UI: deduplicate room participants by fingerprint so ghost entries from
stale relay state don't show duplicates.
Engine: after select! ends, call close_now() + connection.closed() with
500ms timeout to wait for the relay to acknowledge the CONNECTION_CLOSE.
Previously the close frame was queued but the runtime died before quinn
could retransmit if the first packet was lost.

- Partial wake lock + WiFi high-perf lock during calls — audio
continues when screen is off / phone is locked
- Server selector: toggle between LAN (172.16.81.175) and Pangolin
(pangolin.manko.yoga) before connecting
- Room name editable in idle screen

pthread_create crashes on Android due to static bionic __init_tcb stubs
in the Rust std prebuilt rlibs. This is unfixable without rebuilding std.
Solution: run the entire call (QUIC connect, handshake, media send/recv)
on a single tokio current_thread runtime. The JNI startCall() now blocks,
so Kotlin dispatches it to Dispatchers.IO (JVM thread, not pthread).
Audio pipeline temporarily simplified to silence frames — will restore
once threading is solved (either via Java Thread or rebuilding std).

- CallActivity no longer auto-starts a call on launch
- CallViewModel lazily inits engine only when startCall() is called
- nativeGetStats nullable return handled safely in Kotlin
- Removed tracing_subscriber::fmt() which panics on Android (no stdout)
- All JNI calls wrapped in try/catch on Kotlin side
