- 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)

Forgejo doesn't support @actions/artifact v4. Package the tarball
and print sizes instead. Binaries can be grabbed from the runner
workspace or deployed directly.

The Forgejo runner needs Node.js for actions/checkout@v4.
catthehacker/ubuntu:act-latest has Node.js pre-installed.
Also install Rust in the workflow since the base image doesn't have it.
Build triggers on main + feat/* branches now.

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).

The getauxval override (dlsym wrapper) fixes SIGSEGV in
init_have_lse_atomics at library load time. The current_thread
tokio runtime avoids SEGV_ACCERR in pthread_create/__init_tcb.
Both fixes are required together.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Multi-thread tokio runtime crashes with SEGV_ACCERR in __init_tcb
during pthread_create on Android (static bionic stubs from CRT).
Switch to current_thread runtime which runs network I/O on the
calling thread without spawning additional OS threads.
Also: clean up build.rs — use only libc++_shared.so (dynamic),
remove getauxval_fix.c hack, remove static c++/c++abi linking.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
compiler-rt's init_have_lse_atomics calls getauxval(AT_HWCAP) at
library load time. The static getauxval from the CRT reads from
__libc_auxv which is NULL in shared libraries → SIGSEGV at 0x0.
Fix: compile getauxval_fix.c that provides a getauxval() which uses
dlsym(RTLD_DEFAULT) to find the real bionic getauxval at runtime.
Also switch to libc++_shared.so (bundled in APK) to avoid pulling
in static libc stubs.

The .note.android.ident ELF section had API level 0x15 (21), causing
Android's bionic linker to block pthread_atfork (used by rand crate).
Fix: pass -P 26 to cargo-ndk and set linker to android26-clang.
Verified: ELF now shows 0x1a (26).

- Set cpp_link_stdlib(None) to suppress cc crate's automatic linking
- Explicitly link both c++_static and c++abi with NDK sysroot search path
- Fixes RTTI vtable symbol (_ZTVN10__cxxabiv117__class_type_infoE) error
- Verified: only liblog.so remains as dynamic dependency
Closes#001
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Previous fix linked c++_static but not c++abi. Android NDK splits the
static C++ runtime into two archives: libc++_static.a (STL) and
libc++abi.a (RTTI/exceptions). Without c++abi, dlopen fails on
_ZTVN10__cxxabiv117__class_type_infoE.
Now using cpp_link_stdlib(None) to suppress cc crate auto-linking, then
explicitly linking both c++_static and c++abi via cargo:rustc-link-lib.

libc++_shared.so is no longer a runtime dependency — verified
via llvm-readelf. Only system libs (libdl, liblog, libm, libc) remain.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The app crashed immediately when loading libwzp_android.so because the
cc crate's default dynamic linking produced a runtime dependency on
libc++_shared.so, which was never packaged into the APK.
Adding .cpp_link_stdlib(Some("c++_static")) to build.rs bakes the C++
runtime into libwzp_android.so directly, eliminating the missing .so.
See issues/001-libc++-shared-crash.md for full diagnosis and logcat trace.

Detailed implementation plan for adding WS support directly to wzp-relay:
- Abstract Participant over transport type (Quic + WebSocket enum)
- New --ws-port flag for browser connections
- Cross-transport fan-out (QUIC↔WS in same rooms)
- Auth, room management, session cleanup unchanged
- Eliminates wzp-web container entirely

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.

PTT mode was causing delayed/lost audio because:
1. Silence suppression ate the start of speech after PTT release
2. Jitter buffer target depth was too high for interactive use
Web bridge now uses:
- suppression_enabled: false (PTT handles silence at browser level)
- jitter_target: 3 (60ms vs ~1s default)
- jitter_max: 20 (400ms cap)
- jitter_min: 1 (start playing after 20ms)

Client: sends SignalMessage::Hangup(Normal) before closing in all modes
(send-tone, file mode, silence mode) so the relay knows the session ended.
Relay: downgrades "timed out" / "reset" / "closed" recv errors from
ERROR to INFO since these are normal disconnect scenarios.

Replaces the single-shot ephemeral VM approach:
- --prepare: create VM, install deps (Rust, cmake, etc), upload source
- --build: build on VM with full output (iterate on errors)
- --transfer: download binaries to target/linux-x86_64/
- --destroy: delete VM when done
- --upload: re-upload source to existing VM
- --all: prepare + build + transfer (VM persists)
VM reuse: --prepare detects existing wzp-builder VM and just re-uploads.
All steps get VM IP from hcloud server list (last created).
