Siavash Sameni ed8a7ae5aa docs: protocol audit 2026-05-25, update architecture + Obsidian vault
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

Obsidian vault (vault/):
- 114 files across Architecture/, PRDs/, Reports/, Android/,
  Reference/, Audit/ with YAML frontmatter
- 00 - Home.md index note with wiki links
- .obsidian/app.json config

WarzonePhone

Custom lossy VoIP protocol built in Rust. E2E encrypted, FEC-protected, adaptive quality, designed for hostile network conditions.

Quick Start

# Build
cargo build --release

# Run relay
./target/release/wzp-relay --listen 0.0.0.0:4433

# Send a test tone
./target/release/wzp-client --send-tone 5 relay-addr:4433

# Web bridge (browser calls)
./target/release/wzp-web --port 8080 --relay 127.0.0.1:4433 --tls
# Open https://localhost:8080/room-name in two browser tabs

Architecture

See docs/ARCHITECTURE.md for the full system architecture with Mermaid diagrams covering:

  • System overview and data flow
  • Crate dependency graph (8 crates)
  • Wire formats (MediaHeader, MiniHeader, TrunkFrame, SignalMessage)
  • Cryptographic handshake (X25519 + Ed25519 + ChaCha20-Poly1305)
  • Identity model (BIP39 seed, featherChat compatible)
  • Quality profiles (GOOD/DEGRADED/CATASTROPHIC)
  • FEC protection (RaptorQ with interleaving)
  • Adaptive jitter buffer (NetEq-inspired)
  • Telemetry stack (Prometheus + Grafana)
  • Deployment topology

Features

  • 3 quality tiers: Opus 24k (28.8 kbps) / Opus 6k (9 kbps) / Codec2 1200 (2.4 kbps)
  • RaptorQ FEC: Recovers from 20-100% packet loss depending on tier
  • E2E encryption: ChaCha20-Poly1305 with X25519 key exchange
  • Adaptive jitter buffer: EMA-based playout delay tracking
  • Silence suppression: VAD + comfort noise (~50% bandwidth savings)
  • ML noise removal: RNNoise (nnnoiseless pure Rust port)
  • Mini-frames: 67% header compression for steady-state packets
  • Trunking: Multiplex sessions into batched datagrams
  • featherChat integration: Shared BIP39 identity, token auth, call signaling
  • Prometheus metrics: Relay, web bridge, inter-relay probes
  • Grafana dashboard: Pre-built JSON with 18 panels
