- Changed blank-password login behavior to create/manage guest sessions (when read-only is enabled), including replay protection and session timestamp tracking.
- Preserved and centralized `sync_since` handling during successful auth/session updates.
- Updated login handling to return explicit `(success, permissions)` and reset room-server sync guard state in SQLite on successful room-server login.
- Updated identity/banner output in mesh CLI from `pyMC_*` to `openHop_*` and adjusted default version fallback.
- Extended path handling to support encoded path-length semantics via `PathUtils`, with legacy fallback support for older/malformed packets.
- Added bundled ACK extraction from PATH payload extras and callback-based ACK propagation.
- Hardened room-server push logic: max-failure early skip, corrected expected ACK CRC calculation, path encoding compatibility, persisted sync/last-activity fields, and passed expected CRC + timeout into packet injection.
- Enhanced packet router ACK flow with dispatcher ACK registration helper, support for multipart ACK wrapper handling, configurable ACK wait timeout/CRC in injection, and ensured PATH helper processing always runs.
- Updated daemon wiring to pass ACK callback into `PathHelper`,
- make dispatcher dedupe configurable (prevent dbl deduping), and only register duplicate logging hook when dedupe is enabled.
- Expanded tests to cover guest blank-password replay tracking, updated room-server injector ACK expectations, and new duplicate-logging-hook gating behavior.
- Introduced a dedicated thread for broadcasting aggregate statistics to WebSocket clients, improving performance by offloading heavy queries from the packet write path.
- Updated the _publish_packet_sync method to ensure only fast, per-packet operations are executed, while the stats are handled separately.
- Added methods for broadcasting stats at intervals and managing the lifecycle of the stats thread.
- Enhanced unit tests to validate the new stats broadcasting behavior and ensure correct functionality under various conditions.
- Added caching for packet type stats and cumulative counts in SQLiteHandler to reduce database load.
- Implemented a dedicated writer thread in StorageCollector to handle blocking storage operations, preventing asyncio event loop stalls.
- Updated record_packet method to utilize the new writer thread for efficient packet processing.
