Identicon generator:
- Deterministic 5x5 symmetric pattern from fingerprint hash
- HSL-derived colors, rendered as inline SVG
- Click any identicon to copy its fingerprint to clipboard
- Used for participants, user identity, and relay servers
Server identity (TOFU — Trust On First Use):
- Ping returns server fingerprint (QUIC peer certificate hash)
- First contact: auto-saved as known fingerprint
- Subsequent pings: compared against known fingerprint
- Lock icons: locked (verified), unlocked (new), warning (changed), red (offline)
- Fingerprint mismatch shows confirmation dialog before connecting
UI updates:
- Participants show identicons instead of letter avatars
- User identity shows identicon + fingerprint on connect screen
- Manage Relays shows identicon per server with lock status
- Relay button shows lock icon instead of colored dot

- Relay selector as dropdown with green/yellow/red status dots
(green < 200ms, yellow > 200ms, red = offline, gray = unknown)
- All relays pinged on startup, RTT shown next to each
- "Manage Relays..." dialog: add/remove servers, see live status
- Clicking a relay in dropdown selects it, fills connect form
- Recent room chips auto-select matching relay
- Migrates old single-relay settings format automatically
- Prevents connecting to offline relays

- New ping_relay Tauri command: QUIC connect with 3s timeout, returns RTT ms
- Relay status shown next to input field: "42ms" (green) or "offline" (red)

- Fix SyncWrapper dead_code warning with #[allow(dead_code)]

#7 Fingerprint shown before connecting — new get_identity command reads
~/.wzp/identity at startup (generates if missing). Click to copy.
#8 Recent rooms store (relay, room) pairs — clicking a chip fills both
fields. Settings panel shows relay alongside room name. Migrates
old string[] format automatically.
#9 Auto-reconnect on unexpected disconnect — exponential backoff
(1s, 2s, 4s... max 10s), up to 5 attempts. Yellow blinking dot
shows reconnecting state. Stops if user clicks hangup.
#10 Audio handle cleanup — CPAL handles stored in SyncWrapper (no more
mem::forget), dropped properly on CallEngine::stop().

The VPIO/CPAL audio handles were dropped at the end of start(),
killing the audio unit immediately. Audio I/O stopped working
after the first frame.
- Store audio handle in CallEngine via SyncWrapper
- Drop MutexGuard before returning from status() (Send future)
- Audio streams now live for the entire call duration

- Change status() from blocking_lock to async lock().await —
fixes "Cannot block the current thread from within a runtime" panic
that froze the call timer and broke audio
- Click fingerprint to copy to clipboard (both connect and settings screens)
- Show "Copied!" feedback on click

send_datagram() returns Err(Blocked) when the QUIC congestion window
is full. This is transient — the window reopens once ACKs arrive.
Previously, all send paths treated this as fatal (break/return),
which killed the send task and cascaded via tokio::select! to kill
the entire call.
Now: log warning, drop the packet, continue. Brief audio glitch
(20-100ms) instead of complete call death. FEC on the receiver
side recovers most dropped packets.
Fixed in:
- CLI run_live send task (continue + error counter)
- CLI run_file_mode send paths (2 locations)
- Desktop engine send task
Also hardened recv tasks: transient errors (non-closed/reset)
are survived instead of causing exit.
Matches the fix applied to Android client (engine.rs).

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.
