* Improve BLE mesh reliability for large transfers Major reliability improvements for fragment-based transfers (photos, files): **Notification Queue Fixes** - Fix silent packet loss when notification queue is full - now queues for retry - Fix retry queue bug where remaining items were lost when one retry failed - Add periodic drain mechanism as backup (every 5 seconds) **Write Queue Fixes** - Fix drainPendingWrites to use atomic take-send-requeue pattern - Add logging when peripheral is ready for more writes - Add periodic drain for pending writes as backup **Fragment Pacing** - Increase fragment spacing from 4-5ms to 25-30ms to prevent buffer overflow - Conservative pacing prevents packet loss on congested BLE connections **Thread Safety** - Fix race conditions in stopServices() and emergencyDisconnectAll() - Synchronize access to peripherals/centrals dictionaries during cleanup - Clear pending message queues in emergencyDisconnectAll() **Error Recovery** - Add handlers for all BLE state transitions (poweredOff, unauthorized, etc.) - Clear Noise session and re-initiate handshake on decryption failure - Queue ACKs/receipts for delivery after handshake instead of dropping - Re-queue failed pending messages for retry **Other Improvements** - Add route freshness validation in MeshTopologyTracker (60s threshold) - Add TTL (24h) and size limits (100 per peer) for MessageRouter outbox - Fix connection timeout to check peripheral.state before canceling - Add NoiseEncryptionService.clearSession(for:) method Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * Fix race condition and increase test timeouts - Fix race in sendNoisePayload: use sync barrier instead of async to ensure payload is queued before initiating handshake (addresses Codex review feedback) - Increase BLEServiceTests sleep from 0.5s to 1.0s for CI reliability Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> --------- Co-authored-by: jack <jackjackbits@users.noreply.github.com> Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>
