Convert Hold/Unhold/Mute/Unmute/TransferAck from unit variants to struct
variants with `version: u8` (serde default = 2). Every SignalMessage
variant now carries a version field, enabling future semantic versioning
and clean rejection of deprecated variants during federation routing.
305 tests passing.

Deploys wzp-relay to both relay servers after building:
- manwe@manwehs:/home/manwe/wzp (tmux session 5)
- manwe@pangolin.manko.yoga:/home/manwe/wzp-linux (tmux session 0)
Captures current relay args from /proc, stops via tmux C-c, restarts
with same args. Also fixes hardcoded branch default to use current git branch.

C2: Add EncryptingTransport wrapper — all media I/O now goes through
ChaChaSession encrypt/decrypt before hitting the QUIC datagram path.
cli.rs run_live/run_silence/run_file_mode accept Arc<dyn MediaTransport>
and receive a wrapped transport after the handshake.
C3: Wire VideoScorer::observe() into both plain and trunked forwarding
loops in room.rs. Packets from participants with Abusive verdict are
dropped before forwarding. last_bwe_kbps tracked from quality reports.
M4: Widen FEC repair symbol index from u8 to u16 throughout
(FecEncoder::generate_repair, FecDecoder::add_symbol, all call sites in
call.rs, bench.rs, pipeline.rs, wzp-android). Eliminates theoretical
wrapping when num_source + repair_count > 255.
M5: Track last_encrypt_timestamp in ChaChaSession. debug_assert in
encrypt() that timestamp is non-decreasing across calls (including post-
rekey). complete_rekey() explicitly preserves last_encrypt_timestamp to
prevent accidental timestamp reset regressions.
583 tests passing.

- Replace buffer.index() with buffer.buffer_mut()/buffer.buffer() (ndk 0.9 RAII API)
- Replace queue_input_buffer_by_index/release_output_buffer_by_index with
queue_input_buffer/release_output_buffer taking buffer objects
- Fix MaybeUninit<u8> copy using .write() instead of copy_from_slice
- Add BITRATE_MODE_CBR and AMEDIACODEC_BUFFER_FLAG_KEY_FRAME local constants
(removes ndk_sys dependency for these values)
- Add unsafe impl Send for all six MediaCodec wrapper structs
- Pin @tauri-apps/api to ^2.11 to match Cargo.lock tauri 2.11.1

Audit:
- docs/AUDIT-2026-05-25.md: full protocol audit covering 8 findings
(4 critical, 2 high, 5 medium, 4 low) with code references and fix
effort estimates
- vault/Audit/Tasks.md: Obsidian Tasks plugin file tracking all audit
items with priorities, due dates, and per-step checklists
Architecture docs updated for Wire format v2 and Wave 5/6 features:
- ARCHITECTURE.md: adds wzp-video to dependency graph and project
structure; wire format updated to v2 (16B header, 5B MiniHeader);
relay concurrency section corrected (DashMap+RwLock is current, not
a future optimization); test count 571→702; Android note
- PROGRESS.md: Wave 5 and Wave 6 sections appended; test count 372→702;
current status and open blockers as of 2026-05-25
- ROAD-TO-VIDEO.md: implementation status table inserted (✅/🟡/🔴/🔲
per phase); 6-step critical path to first video call
- WZP-SPEC.md: MediaHeader updated to v2 (16B byte-aligned); MiniHeader
updated to 5B with seq_delta; codec IDs 9-12 added (H.264/H.265/AV1);
version negotiation section added

The previous scheme built ChaCha20-Poly1305 nonces from an internal
recv_seq counter that incremented once per decrypt() call. Under
in-order delivery recv_seq stayed in sync with the sender's send_seq,
but any out-of-order or lost packet caused them to diverge permanently —
every subsequent packet then used the wrong nonce and AEAD decryption
failed for the rest of the session.
Fix: parse the MediaHeader at the top of both encrypt() and decrypt()
and use header.seq as the nonce input. Both sides now derive the nonce
from the same wire field, surviving reordering by construction.
send_seq / recv_seq are kept as pure packet counters for the rekey
interval trigger; they no longer affect nonce derivation.
All tests updated to pass valid v2 MediaHeader bytes instead of raw
byte literals (the new code requires a parseable header for nonce
derivation). New test decrypt_survives_out_of_order_delivery encrypts
5 packets and delivers them out of order (indices 0,2,1,4,3); this
test would have failed under the old counter-based scheme.
Fixes audit finding C1 from AUDIT-2026-05-25.md.

shiguredo_dav1d and shiguredo_svt_av1 build scripts panic with
'unsupported target: os=android, arch=aarch64'. The AV1 SW fallback
is only needed on macOS / Linux desktop — Android uses MediaCodec
for AV1 anyway.
- Cargo.toml: AV1 SW deps moved under cfg(not(target_os = "android"))
- lib.rs: cfg-gate the dav1d and svt_av1 modules and re-exports
- factory.rs: on Android, Av1Main paths return NotInitialized when
HW MediaCodec is also unavailable (only path on Android)
- factory tests: assert NotInitialized on Android, Ok elsewhere
Unblocks T4.3.1.1 (Android target-compile of wzp-video / mediacodec).

Two pre-existing PASTE_AUTH tokens in scripts/build.sh and
scripts/build-linux-notify.sh are real and should be rotated if the
paste.tbs.amn.gg / paste.dk.manko.yoga endpoints still authenticate
— this allowlist only silences the pre-push hook, it does not
remove the exposure.

- Refactor should_forward_pli(room, stream_id) -> should_forward_pli(room, stream_id, now: Instant)
so the 200 ms dedup window is deterministically testable.
- Update the one caller in run_participant_signals to pass Instant::now().
- Add 6 PLI unit tests covering:
* first PLI forwards
* duplicate within 200 ms suppressed
* after 200 ms forwards again
* different streams independent
* different rooms independent
* no stream owner returns None
Addresses reviewer CR on T4.7 (line drawn at T4.6 — stateful relay features must
have state-transition tests).
wzp-relay tests: 93 -> 99 pass.
