- Removed stale KeyExchange re-export from crypto/mod.rs (kex.rs
only exports HybridSharedSecret and HybridKex after stub refactor)
- Removed unused imports in ostp-server/lib.rs (AsyncWriteExt,
tcp::OwnedWriteHalf)
- Suppressed dead_code warning on HelperMsg::Log variant (IPC spec)
- Verified: cargo check passes with zero errors and zero warnings
- Unified log prefix to [ostp] across all modules (was [OSTP Core],
[ostp-server], [ostp-client], [client], [bridge])
- Removed informal/casual phrasing from all user-visible messages
- Startup messages are clean and concise (mode, server, status)
- Error messages are actionable without being alarming
- Essential server logs (client connect/disconnect) always visible
- Essential client logs (connection status, errors) always visible
- TUN tunnel messages consistent across Windows and Linux
- Removed noisy eprintln from UDP reader hot path
- Status format: [ostp] Status: Connected (rtt=12.3ms)
Critical fixes (6):
- protocol.rs: in_flight_count() now counts only retransmittable Data frames,
not Ack/Nack control frames — eliminates false backpressure under load
- protocol.rs: NACK is now rate-limited to once per 30ms — prevents
retransmission storm during normal UDP jitter
- protocol.rs: zombie frames exceeding max_retries+4 are evicted each tick —
prevents unbounded memory growth and stale retransmits
- protocol.rs: Closing state now processes final in-flight packets instead
of silently dropping them — prevents data loss at session teardown
- server/lib.rs: stream_tx changed from bounded(10000) to unbounded_channel —
prevents TCP-reader collapse during Speedtest with 50+ streams
- bridge.rs: liveness timeout raised from 30s to 60s — prevents false
reconnect during heavy Speedtest load
Medium fixes (8):
- protocol.rs: ACK range truncation preserves cumulative range (index 0)
- bridge.rs: Ping now uses send_datagram() for correct TURN wrapping
- dispatcher.rs: replay_cache hard-capped at 100k entries (DoS protection)
- dispatcher.rs: old addr cleaned from addr_to_session on roaming
- server/lib.rs: TCP connect_target() now has 10s timeout
- config.rs: TURN section parsed during hot-reload
- proxy.rs: HTTP header parsing uses 512-byte chunks instead of 1-byte reads
- proxy.rs: stream_id wrap-around skips active IDs to prevent collision
- runner.rs: is_essential_log matches actual log strings from bridge.rs
Other:
- kex.rs: clearly marked as dead PQ stub (not used by protocol)
- README.md + README.ru.md: complete rewrite with architecture diagram
- docs/en/specification.md: updated ARQ section with all new semantics
