fix: security hardening — 40 findings from full codebase review
Full codebase review by 4 independent agents (security, architecture,
code quality, correctness) identified ~80 findings. This commit fixes 40
of them across all workspace crates.
Critical fixes:
- Federation service: validate origin against mTLS cert CN/SAN (C1)
- WS bridge: add DM channel auth, size limits, rate limiting (C2)
- hpke_seal: panic on error instead of silent empty ciphertext (C3)
- hpke_setup_sender_and_export: error on parse fail, no PQ downgrade (C7)
Security fixes:
- Zeroize: seed_bytes() returns Zeroizing<[u8;32]>, private_to_bytes()
returns Zeroizing<Vec<u8>>, ClientAuth.access_token, SessionState.password,
conversation hex_key all wrapped in Zeroizing
- Keystore: 0o600 file permissions on Unix
- MeshIdentity: 0o600 file permissions on Unix
- Timing floors: resolveIdentity + WS bridge resolve_user get 5ms floor
- Mobile: TLS verification gated behind insecure-dev feature flag
- Proto: from_bytes default limit tightened from 64 MiB to 8 MiB
Correctness fixes:
- fetch_wait: register waiter before fetch to close TOCTOU window
- MeshEnvelope: exclude hop_count from signature (forwarding no longer
invalidates sender signature)
- BroadcastChannel: encrypt returns Result instead of panicking
- transcript: rename verify_transcript_chain → validate_transcript_structure
- group.rs: extract shared process_incoming() for receive_message variants
- auth_ops: remove spurious RegistrationRequest deserialization
- MeshStore.seen: bounded to 100K with FIFO eviction
Quality fixes:
- FFI error classification: typed downcast instead of string matching
- Plugin HookVTable: SAFETY documentation for unsafe Send+Sync
- clippy::unwrap_used: warn → deny workspace-wide
- Various .unwrap_or("") → proper error returns

feat: Sprint 8 — TypeScript SDK with WASM crypto and browser demo
- WASM crypto bundle (175KB): 13 wasm_bindgen functions wrapping
quicproquo-core's Ed25519 identity, X25519+ML-KEM-768 hybrid KEM,
safety numbers, sealed sender, and message padding
- @quicproquo/client TypeScript SDK: QpqClient class with connect,
health, resolveUser, createChannel, send/sendWithTTL, receive,
deleteAccount; WebSocket transport with request/response correlation
and reconnection; ergonomic crypto.ts wrapper over WASM functions
- Browser demo: vanilla HTML page with interactive crypto operations
(identity gen, safety numbers, sign/verify, hybrid encrypt/decrypt,
sealed sender, padding) and chat UI for server connectivity
- Offline mode: crypto operations work without server connection
TypeScript strict mode, 0 errors. WASM bundle size optimized (lto + opt-level=s).
