Divergence catches abusers who send audio-rate small packets but burn fields for payload. + +### Tier D — Per-codec packet-size sanity + +EWMA of packet size per session, compared to per-codec typical: + +| Codec | Typical | Reject above | +|---|---|---| +| Opus 24k 20 ms | 60–80 B | 160 B | +| Opus 6k 40 ms | 30–40 B | 90 B | +| Codec2 1200 40 ms | 6 B | 30 B | +| ComfortNoise | 0–4 B | 16 B | + +### Tier E — Per-fingerprint / per-IP token bucket + +Aggregate quota regardless of declared codec: + +``` +For each (fingerprint, src_ip): + monthly_bytes_quota authenticated = 50 GB (tune) + anonymous = 1 GB + per-session cap audio = 256 kbps + video = 5 Mbps + burst = 30 s at 2× cap +``` + +Won't stop a single rogue session under cap; bounds aggregate blast radius and makes relay economics predictable. + +### Tier F — Behavioral entropy / statistical fingerprinting + +The deeper layer. Computed continuously per session over 10–30 s windows. Combined score flags streams that pass declared-codec checks but do not statistically look like real media. + +**Why this works:** real audio and real video have very specific statistical signatures that tunneled data does not naturally produce, and that an attacker would have to deliberately and expensively mimic. The signatures differ wildly between audio and video — which is exactly why we separate them (see next section). + +#### Audio fingerprint features + +| Feature | Real Opus speech | Tunneled data | +|---|---|---| +| **IAT coefficient of variation** | 0.1–0.4 (clocked) | > 1.0 (bursty) | +| **Payload-size distribution** | Bimodal: speech 60–80 B + silence/CN 0–10 B | Unimodal, large, MTU-skewed | +| **Silence fraction** | 10–40 % (real conversation pauses) | < 2 % | +| **Bitrate over 30 s** | Tracks nominal codec ±20 % | Often saturates ceiling | +| **`Q` flag cadence** | Periodic, regular | Absent or random | +| **DRED / FEC ratio response** | Tracks `QualityReport` trend | Static or noise | + +Single derived score: `audio_legitimacy ∈ [0, 1]`.

Always close with a typed reason so legitimate users hitting a bug get a clear error. + +## Separating audio and video + +**Yes — this is one of the strongest arguments for the v2 `MediaType` bit and should be a hard design rule.** + +Audio and video have nothing in common statistically: + +| Property | Audio | Video | +|---|---|---| +| Bitrate | 6–64 kbps | 100 kbps – 5 Mbps | +| Packet rate | 25–50 pps | 500–2000 pps | +| Packet size | 6–160 B | 200–1450 B | +| Burst structure | Clocked, near-CBR | Bursty (I-frames) | +| Silence | Common (10–40 %) | Meaningless | +| Loss tolerance | High (PLC, DRED) | Variable (keyframes critical) | +| Recovery primitive | FEC + DRED | NACK + PLI + keyframe cache | + +A single scoring model trying to cover both would have to be so permissive at the union of envelopes that it would let tunnels through. **Separation is mandatory for Tier F to work.** + +### What separation requires + +1. **`MediaType:2` in `MediaHeader` v2** (already in `ROAD-TO-VIDEO.md` Phase V1). Without this, the relay must keep a `CodecID → MediaType` table and update it every time a codec is added — fragile. +2. **Per-`MediaType` conformance rules.** A and B and D have separate tables per type. Tier F has separate scorers. +3. **Per-`MediaType` quotas.** Tier E uses two buckets: `audio_bps_cap`, `video_bps_cap`. A session in audio-only mode never gets to spend the video budget. A video session has both, audio-priority. +4. **Per-`MediaType` keyframe/silence semantics.** `KeyFrame` bit is meaningless for audio; silence fraction is meaningless for video. The scorer needs to know which features apply. + +### Bonus: separation also helps the SFU + +Beyond abuse detection, the same separation makes graceful degradation cleaner: under congestion the relay can drop video packets first while preserving audio, because it knows which is which without parsing the codec table. + +## Open questions for later decision + +1. **Hard-close on first hard violation, or three-strikes?** Three-strikes is friendlier but lets twice the abuse through. Recommend hard-close + clear typed reason; legitimate users will reconnect, abusers won't try again at the same fingerprint. +2. **Where do verdicts persist?** In-memory per relay is simplest. Federated gossip is more powerful but a new attack surface (poisoning). +3. **Threshold tuning.** All thresholds in this doc are first-pass math. Real numbers come from a few weeks of Prometheus data on legitimate traffic before any enforcement turns on. +4. **Anonymous vs. authenticated split.** featherChat-authed users get generous quotas; anonymous users get tight ones. This makes the economics of mass abuse hostile (need many real identities) without locking out small legitimate use. +5. **What to log.** Conformance hits should be Prometheus counters + ringbuffer of recent violations; never log raw payload content (even encrypted) for privacy. + +## Suggested implementation order (whenever this is picked up) + +| Step | What | Why first | +|---|---|---| +| 1 | Land v2 wire format with `MediaType:2` | Prereq for separation; already on the road-to-video plan | +| 2 | Tier A + B + C as `wzp-relay/src/conformance.rs` | Kills bulk tunneling; cheap; no false positives if math is right | +| 3 | Prometheus metrics for violations + raw observables (IAT, size, silence frac) | Gather baseline of legitimate traffic before tightening | +| 4 | Tier D + E (size sanity + token bucket) | Defense in depth | +| 5 | Tier F scorer, audio-only first; tuned against the baseline from step 3 | Adds covert-tunnel pressure | +| 6 | Tier F video scorer once video is in production | Same shape, different features | +| 7 | Tier G response policy + audit log | Operationalize | + +Steps 1–2 are decisive against the LiveKit-style PoC.

Quinn's `PathSnapshot` feeding `DredTuner` is something WebRTC stacks build from scratch. +- **Continuous DRED tuning.** Mapping RTT / loss / jitter to a continuous Opus DRED lookback window is genuinely better than discrete tiers — most stacks treat DRED as on/off. +- **MiniHeader (49/50).** At 50 pps that is ~400 B/s saved per stream; meaningful at scale. +- **SFU never decodes.** Preserves E2E. Most SFUs (LiveKit, Janus) terminate SRTP at the SFU. +- **RaptorQ for low-bitrate Codec2 + DRED for Opus.** Correct split — DRED is cheaper than FEC at high bitrate; RaptorQ shines when you can afford many small symbols. + +## Weaknesses + +### W1. `u16` sequence wraps every ~21 minutes at 50 pps +Anti-replay window is 64 packets so wrap is safe for replay. **But** the jitter buffer's `BTreeMap` will misorder across the wrap boundary if a packet is delayed more than ~32 k frames. Widen to `u32` (or version the field). + +### W2. `fec_block_id: u8` wraps every 256 blocks (~25 s at 5-frame blocks) +A late-joining peer or a slow reconstructor can collide block IDs. Widen to `u16` or carry an epoch counter. + +### W3. `timestamp_ms` rebase behavior at rekey is unspecified +Rekey every 65,536 packets (~22 min). If `timestamp_ms` resets, downstream sync glitches. If it does not, document explicitly. + +### W4. `MiniHeader` has no `seq` +Receiver infers absolute seq from the most recent full header + frame count. One missed full header (every 50 frames = 1 s) leaves 49 packets with unknown absolute seq. Acceptable for audio with short jitter buffers — **fatal for video** where one missed full header can desync an entire GOP. **Add `seq_delta: u8` to MiniHeader before video lands.** + +### W5. `QualityReport` placement vs. AEAD +A 4-byte trailer on encrypted media is fine **iff it sits inside the AEAD payload**. If it is outside, anything stripping the last 4 bytes corrupts decryption and creates a downgrade vector. Verify in `packet.rs`; if outside, move it inside or AAD-bind it. + +### W6. Adaptive controller is loss / RTT-only — no bandwidth estimator +Quinn exposes `cwnd` and `bytes_in_flight`, but `AdaptiveQualityController` does not consume them. Under low utilization you cannot detect that you *could* upgrade to Opus 64 k. **For video this is mandatory** — without BWE you will either oscillate or never use available capacity. + +### W7. No NACK / explicit retransmit path +For audio with DRED + FEC this is fine. For video keyframes it is wasteful — an I-frame is 50–200 packets, protecting at 50 % FEC doubles bitrate. A NACK path is cheap and far cheaper than blanket FEC for I-frames. + +### W8. TrunkFrame batching multiplies AEAD cost +Each inner payload is its own AEAD operation. At 10 entries that is 10× ChaCha calls per recv. Fine on x86 / ARM with AES-NI / NEON; profile on weak Android (Nothing A059 baseline). + +### W9. `CodecID` is 4 bits → max 16 codecs; 9 already used +Adding H.264, H.265, AV1, VP9 takes you to 13. Land the widening **before** deployment — either steal from `reserved` / `csrc_count` to make CodecID 8-bit, or split into `MediaType:2 / CodecID:6`. Doing this post-deployment is painful. + +### W10. No `MediaType` field +Audio vs. video vs. data is implicit in CodecID. A 2-bit `MediaType` lets the SFU apply per-type policy (drop video first under congestion, prioritize audio fan-out) without a codec lookup. + +### W11. Anti-replay window 64 packets is tight for video +One keyframe burst can be 100+ packets; a single reordered earlier packet stalls the window. Bump to 256 or 1024 for video streams, or maintain a per-stream window. + +### W12. `SignalMessage` has no version byte +Bincode + `#[serde(default, skip_serializing_if)]` covers field additions but not variant removal or semantic change. Lead every variant with `version: u8`. + +### W13. RoomManager Mutex per-packet +Already flagged in `ARCHITECTURE.md`. At ~1500 pps/sender for video this becomes a real ceiling. `DashMap>>` is a Sunday afternoon. + +### W14.
