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.

- Add SettingsScreen with identity (alias, key backup/restore), audio defaults,
server management, network prefs, and default room
- SettingsRepository persists all settings via SharedPreferences
- Auto-generate random display names on first launch (e.g. "Swift Wolf")
- Thread alias through CallOffer → relay handshake → RoomUpdate broadcast
- Derive caller fingerprint from identity key in relay handshake (fixes null
fingerprints when --auth-url is not set)
- Persist identity seed for stable fingerprints across reconnects
- Add alias field to SignalMessage::CallOffer (serde default for backward compat)

RelayLink: QUIC connection to peer relay (SNI "_relay") for forwarding
specific sessions. Methods: connect, forward, add/remove_session, is_idle.
RelayLinkManager: manages connections to multiple peers.
- get_or_connect: lazy connection establishment
- forward_to: send media packet to specific peer
- register/unregister_session: track which sessions use which links
- Auto-closes idle links on session unregister
Protocol: added SignalMessage::SessionForward { session_id,
target_fingerprint, source_relay } and SessionForwardAck { session_id,
room_name } for relay-link session setup signaling.
Building block for P3-T7 (call setup over mesh) which wires
route resolution + relay links + handshake into a complete flow.
62 relay tests + 42 proto tests passing (7 new relay_link tests).

RouteResolver queries PresenceRegistry to determine how to reach a target:
- Route::Local — connected to this relay
- Route::DirectPeer(addr) — on a directly connected peer relay
- Route::Chain(addrs) — multi-hop (structure ready, single-hop for now)
- Route::NotFound — not in any known relay
Protocol: added SignalMessage::RouteQuery { fingerprint, ttl } and
RouteResponse { fingerprint, found, relay_chain } for peer-to-peer
route queries over probe connections.
HTTP API: GET /route/:fingerprint returns JSON with route type + chain.
Relay handles incoming RouteQuery on probe connections: looks up locally,
replies with RouteResponse. TTL decremented for future multi-hop forwarding.
55 relay tests + 42 proto tests passing (7 new route tests).

PresenceRegistry tracks who is connected where:
- register_local/unregister_local for directly connected users
- update_peer for fingerprints reported by peer relays
- lookup returns Local or Remote(addr)
- expire_stale removes entries older than timeout
Gossip via probe connections:
- New SignalMessage::PresenceUpdate { fingerprints, relay_addr }
- Probes send local fingerprints every 10s alongside Ping/Pong
- Receiving relay updates its remote presence table
HTTP API on metrics port:
- GET /presence — all known fingerprints + locations
- GET /presence/:fingerprint — single lookup
- GET /peers — peer relays + their connected users
Wired into relay main:
- Registry created at startup
- register_local after auth+handshake
- unregister_local on disconnect
- Passed to probe mesh and metrics server
Also marks FC-10 as DONE in integration tracker.
48 relay tests + 42 proto tests passing.

T6 wiring: Trunking in relay hot path
- TrunkedForwarder wraps transport with TrunkBatcher
- run_participant uses 5ms flush timer when trunking enabled
- send_trunk/recv_trunk on QuinnTransport
- --trunking flag on relay config
- 2 new tests: forwarder batches, auto-flush on full
T7 wiring: Mini-frames in encoder/decoder
- MediaPacket::encode_compact/decode_compact with MiniFrameContext
- CallEncoder sends mini-headers for consecutive frames (full every 50th)
- CallDecoder auto-detects full vs mini on receive
- mini_frames_enabled in CallConfig (default true)
- 3 new tests: encode/decode sequence, periodic full, disabled mode
Noise suppression (nnnoiseless/RNNoise)
- NoiseSupressor in wzp-codec: pure Rust ML-based noise removal
- Processes 960-sample frames as two 480-sample halves
- Integrated in CallEncoder before silence detection

- 4 new tests: creation, processing, SNR improvement, passthrough
T1-S4: Adaptive playout delay

WZP-S-4: Room access control
- hash_room_name() in wzp-crypto: SHA-256("featherchat-group:"+name)[:16]
- CLI --room flag hashes before SNI, web bridge does the same
- RoomManager gains ACL: with_acl(), allow(), is_authorized()
- join() returns Result, rejects unauthorized fingerprints
WZP-S-5: Crypto handshake wired into all live paths
- CLI: perform_handshake() after connect, before any mode
- Relay: accept_handshake() after auth, before room join
- Web bridge: perform_handshake() after auth, before audio
- Relay generates ephemeral identity at startup
WZP-S-6: Web bridge featherChat auth
- --auth-url flag: browsers send {"type":"auth","token":"..."} as first WS msg
- Validates against featherChat, passes token to relay
- --cert/--key flags for production TLS (replaces self-signed)
WZP-S-7: wzp-proto standalone
- Cargo.toml uses explicit versions (no workspace inheritance)
- FC can use as git dependency
WZP-S-9: All 6 hardcoded assumptions resolved
- Auth, hashed rooms, mandatory handshake, real TLS certs,
profile negotiation, token validation
CLI also gains --room and --token flags.
179 tests passing across all crates.

WZP-S-2: Relay token authentication
- New --auth-url flag: relay calls POST {url} with bearer token

- New auth.rs module with validate_token() + tests
WZP-S-3: featherChat signaling bridge
- New featherchat.rs module for CallSignal interop
- WzpCallPayload: wraps SignalMessage + relay_addr + room name
