CRITICAL (5):
- Hub panic recovery now calls h.Stop() after 3 panics (ws/hub.go)
- Ring buffer EventsSince returns non-nil empty slice for current seq (ws/ringbuffer.go)
- PTT event listener stores unsubscribe handle to prevent leak (ptt.ts)
- verifyTotp respects config.allowSelfSigned instead of hardcoding (api.ts)
- ptt_listen_for_key uses spawn_blocking to avoid thread pool starvation (ptt.rs)
HIGH - Server (13):
- TOTP rate-limit checked after body decode; counters reset on success
- TOTP enable returns 409 if already enabled (must disable first)
- Global search pre-computes accessible channel IDs for FTS WHERE clause

- Updater download uses probe pattern instead of overflow write
- Webhook checks Authorization header before reading body
- Storage.Save adds fsync and fixes double-close
- Default WS origin denies cross-origin (was: accept all)
HIGH - Client (6):
- WS reconnect uses generation counter to discard stale events

- Screenshare mute state preserved across reconnect (not full leave)
- handleVoiceToken uses iterative loop instead of unbounded recursion
- store.ts re-entrancy guard with pending update queue
- Notification AudioContext cleaned up on logout

Move handleVerifyTOTP, handleEnableTOTP, handleConfirmTOTP, and
handleDisableTOTP along with their request/response types into a
dedicated totp_handler.go file, bringing auth_handler.go from 829
to 583 lines.
Add audit log calls for TOTP lifecycle events:
- totp_verified on successful 2FA login verification
- totp_enabled on successful TOTP enrollment confirmation
- totp_disabled on successful TOTP removal
Cover low-coverage handler functions: handleGetPins, handleSetPinned,
handleMetrics, handleDiagnosticsConnectivity, isPrivateIP, AdminIPRestrict,
handleClientUpdate, and handleLiveKitHealth. Adds 30 new test cases across
4 new test files and 2 modified test files.
Comprehensive tests for handleUpload and handleServeFile covering:
- Route mounting verification
- Successful text and PNG uploads with response validation
- Authentication enforcement (missing/invalid tokens)
- Missing file field and invalid multipart form
- Blocked file types (PE, ELF, Mach-O, shell scripts)
- DB record creation and unlinked message_id
- File serving with correct Content-Type, Cache-Control, Content-Disposition
- File not found (missing DB record and missing storage file)
- CORS headers (matching, non-matching, wildcard, no origin)
- Full upload-then-serve round-trip for text and PNG
Coverage: MountUploadRoutes 100%, handleUpload 78.6%, handleServeFile 83.9%
- Add auto-login toggle on server profiles (lightning bolt icon, single-server
enforcement). On startup, auto-connects with saved credentials; falls back
to login form on failure or 2FA.
- Add online_users field to /api/v1/health endpoint (Go server) and display
user count on server cards in the login page.
- Add periodic health check retry every 15s while on ConnectPage so offline
servers update when they come back online.
- Move DM section above text channels in sidebar, limit to 3 visible DMs
with "View all messages" button for overflow.
- DMs with new messages bubble to top of the list automatically.
- Add total unread badge on DM header (visible even when collapsed).
- Member list collapses to just header bar; state persisted across sessions.
Security fixes (from multi-reviewer code review):
- Add DM participant auth checks to channel_focus, typing, and REST
message endpoints — prevents unauthorized access to DM channels
- Fix TOCTOU race in GetOrCreateDMChannel using IMMEDIATE transaction
- Validate YAML credentials before LiveKit config interpolation
- Add CSS variable injection prevention in custom theme loader
- Validate localStorage JSON before unsafe type casts
LiveKit stability:
- Track remote mic audio elements for cleanup on abnormal disconnect
- Remove duplicate token refresh timer scheduling
- Add .catch() to all floating applyMicMuteState promises
- Clear reconnectAc after async post-connect work completes
- Fix double cmd.Wait() race in LiveKit process Stop()
- Reorder voice_join guards: validate channel before livekit==nil check
- Add startup warning for external LiveKit webhook CIDR mismatch
DM system fixes:
- Emit dm_channel_close WebSocket event from REST close handler
- Re-open DM for caller when channel already exists
- Fix unread count incrementing for own messages and active DMs
- Reset channelBeforeDm after Back navigation (stale state bug)
New feature:
- Voice call duration timer in VoiceWidget (MM:SS / HH:MM:SS elapsed)
- Accent color restored on app startup (was only applied in settings)
Test infrastructure:
- Add DM tables to all test schemas (hubTestSchema)
- Inject test LiveKit client in voice handler tests (fixes 28 failures)
Task A: REST API endpoints in api/dm_handler.go — POST /api/v1/dms
(create/get DM channel), GET /api/v1/dms (list open DMs), DELETE
/api/v1/dms/{channelId} (close DM). Routes registered in router.go.
Task B: WebSocket DM routing — handleChatSend, handleChatEdit,
handleChatDelete, and handleReaction all check channel type and use
participant-based auth for DM channels instead of role permissions.
DM messages delivered via SendToUser to each participant (bypassing
channel-subscription model). Auto-reopens DM for recipient on new
message with dm_channel_open event. New broadcastToDMParticipants
helper. New WS event types: dm_channel_open, dm_channel_close.
Task C: Ready payload includes dm_channels from GetUserDMChannels.
Also adds GetDMParticipantIDs helper to db/dm_queries.go.

Voice was broken over NAT due to multiple issues across the audio pipeline:
- Fix GainNode silence: WebView2 silences remote WebRTC streams routed through
Web Audio createMediaStreamSource→GainNode→createMediaStreamDestination.
Replaced with direct HTMLAudioElement playback for remote audio.
- Fix NAT traversal: Add Google public STUN server (stun.l.google.com:19302)
so remote clients can discover their public IP for ICE connectivity.
- Fix signaling race: Catch createOffer InvalidStateError when server
renegotiation offer arrives before client's initial offer is sent.
- Fix device switch: Use replaceTrack() instead of removeTrack+addTrack
to avoid SDP renegotiation. Safe rollback on failure (stop old last).
- Fix speaking flicker: setSpeakers skips local user (VAD is sole authority).
- Fix VAD sample rate: Force 48kHz AudioContext instead of system default
(192kHz) which spread FFT bins too wide for voice frequency detection.
- Fix CSP for WASM: Add wasm-unsafe-eval to script-src for RNNoise.
- Fix clearAuth leak: leaveVoice() called before resetVoiceStore().
- Fix ICE rate limit: Separate limit for ICE candidates (50/s vs 20/s).
- Fix stale ICE errors: Silently drop voice_ice with no PeerConnection.
- Fix audio play() race: Deferred to queueMicrotask after DOM attachment.
Debugging infrastructure:
- Logs tab: Copy All button, Voice Diagnostics panel with live session
state, Probe Audio Levels (measures actual signal at 3 pipeline points),
Test Direct Playback button, Copy Diagnostics button.
- Client logging: WebRTC (PeerConnection lifecycle, ICE candidates with
type/address, track events, negotiation), VAD (start/threshold/destroy),
Audio (device acquisition with settings, device changes), noise suppression
(WASM load timing, worklet vs fallback path), voiceSession (remote stream
parsing failures, deafen state, audio element playback events).
- Server logging: SFU init config, voice room mode transitions/track
lifecycle/close, RTP forwarding with packet counts and first-packet
detection, 5s no-packet warning, track fan-out counts, subscriber
transceiver state, ICE candidate details, voice credentials issued.
- Logger: Error objects now serialize .message and .stack instead of {}.
Per-user volume right-click now works on voice user rows in sidebar.
RNNoise ML noise suppression with AudioWorklet + ScriptProcessor fallback.
Tests: 7 new test cases (replaceTrack, setSpeakers skip-local, clearAuth).

message list scroll, quick switcher, and profile management
Fix 70+ errcheck violations by adding explicit error discards (`_ =`)
for unchecked return values across test helpers and deferred Close()
calls. Remove unused `senderID` field from broadcastMsg and unused
`defaultCleanupMaxWindow` const. Apply De Morgan's law, remove empty
branch, and simplify redundant type declaration per staticcheck.
