1e729e4b1d T6.3: Design exploration for federated reputation gossip 
Add docs/PRD/PRD-relay-federation-gossip.md comparing 3 approaches:
1. Push gossip — relay broadcasts RepeatAbusive verdicts to peers
2. Pull oracle — peers query a reputation oracle periodically
3. Ban-list distribution — admin signs and pushes authoritative list

For each: wire format, Sybil resistance, convergence, storage,
partition tolerance, failure modes. Open questions block implementation
(trust model, privacy leakage, key infrastructure). Move T6.3 to Blocked
pending reviewer design call.

086d0a4845 T6.1.2: Wire AV1 into call engine (factory + step tables) 
- New: factory.rs — create_video_encoder/decoder dispatch by CodecId with
  platform-aware HW→SW fallback. AV1 encoder: SvtAv1Encoder (universal SW).
  AV1 decoder: VideoToolboxAv1Decoder (macOS M3+) → MediaCodecAv1Decoder
  (Android) → Dav1dDecoder (all platforms fallback).
- controller.rs: codec-specific step tables (H.264/H.265/AV1). AV1 ~30%
  lower thresholds than H.264; H.265 ~20% lower. VideoQualityController
  gains codec field with with_codec()/set_codec()/codec() accessors.
- lib.rs: export factory fns and VideoToolboxAv1Decoder
- wzp-client/Cargo.toml: add wzp-video dependency
- 11 new tests (7 factory + 4 controller); 77→88 wzp-video tests; fmt +
  clippy clean; all workspace tests pass

9334aa5ccd T6.1: AV1 encoder/decoder with HW probe + SVT-AV1 SW fallback 
- New: av1_obu.rs — OBU framer, depacketizer, keyframe detection, LEB128 helpers
- New: dav1d.rs — SW AV1 decoder wrapper (shiguredo_dav1d)
- New: svt_av1.rs — SW AV1 encoder wrapper (shiguredo_svt_av1)
- Add CodecId::Av1Main = 12 with match-arm fixes in downstream crates
- Add VideoToolboxAv1Decoder for macOS M3+ HW decode
- Add MediaCodecAv1Encoder/Decoder for Android (video/av01)
- Add extract_sequence_header_obu() helper for AV1 decoder CSD
- Add 10-frame encode-decode roundtrip test (svt_av1 + dav1d)
- Fix clippy unused import in dav1d.rs
- 15 tests; all workspace tests pass; cargo fmt clean

001d94f9ae T4.7 rework: make should_forward_pli take now: Instant + 6 unit tests 
- 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.

cc5aef2534 T4.5: I-frame FEC ratio boost — keyframe-aware repair ratio in RaptorQFecEncoder 
- Add add_source_symbol_with_keyframe() default method to FecEncoder trait
- RaptorQFecEncoder tracks has_keyframe per block, uses keyframe_ratio
  when generating repair symbols for keyframe blocks
- AdaptiveFec gains keyframe_repair_ratio (default 0.5) and wires it
  through build_encoder()
- 3 new tests: keyframe boost, non-keyframe nominal ratio, finalize clears flag
- Update status board T4.5 -> Pending Review
