Siavash Sameni	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.	2026-05-12 19:13:31 +04:00

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.

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

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
