Implements the two highest-impact gaps from the client UX spec.
Optimistic send:
- messages.store gains addOptimisticMessage / markSendFailed /
removeOptimistic, and confirmSend now stamps the real id + "sent" on
the ack. addMessage reconciles the broadcast by real id (idempotent,
replay-safe) with a defensive author match, so an echo never
duplicates. Message gains status/correlationId/errorCode.
- ChannelController.performSend renders a pending row immediately and
supports retry / delete-draft (retry preserves attachments).
- MessageList renders pending (dimmed) and failed (reason + Retry /
Delete) rows; the hover action bar is limited to confirmed rows.
- Failures are precise: the server echoes the request id on error
replies (buildErrorMsgWithID), so the dispatcher maps SLOW_MODE /
FORBIDDEN / RATE_LIMITED / BAD_REQUEST to the exact row instead of
dropping the code. An offline send is shown failed, not silently lost.
Composer permission + connection gating:
- The server computes an authoritative per-channel can_send in the ready
payload (channelCanSend mirrors MessageService.checkSendPermission:
READ|SEND, MANAGE_MESSAGES for announcement, admin bypass, channel
overrides). channels.store carries it as Channel.canSend.
- MessageInput gains a disabled-with-reason mode; ChannelController
derives the reason from can_send + channel type + connection status and
disables the composer reactively (announcement read-only, no-permission,
reconnecting) rather than accepting a click and failing. Older servers
that omit can_send default permissive.
Docs: the corresponding "Current gap" callouts in docs/architecture/ux
are updated to reflect the implementation.
Verified: full server suite + client tsc + 3204 unit tests + lint + gofmt.

- Remove commented-out code flagged by gocritic
- Use bytes.Equal instead of string conversion comparison
- Remove unused buildRateLimitError function
- Remove unnecessary type assertions in e2eeCrypto.ts
- I-1: Add key holder election in Hub (lowest userID per channel); reject
non-key-holder voice_e2ee_offer with NOT_KEY_HOLDER error
- I-2: Accept raw (unpadded) base64 in E2EE announce/offer handlers via
decodeBase64Loose fallback
- I-6: Copy E2EE public key value while h.mu.RLock is held in getClientE2EEPubKey
- I-7: Lower loginRateLimitPerMinute from 60 to 5
- C-1: TOCTOU fix — target channel check held under same lock as client lookup
- C-2: Include is_key_holder bool in voice_token payload so client knows
whether to initiate key distribution
- M-5/M-6: Add ErrCodeBadPayload/ErrCodeNotKeyHolder error constants
- Fix pre-existing api build errors: block_handler.go getUserFromContext,
router.go RequirePermission arg count
- Add user_blocks table to all test DB schemas (ws, api DM)
- Add voice_e2ee_test.go and constants_test.go covering all fixes
Replace server-generated symmetric keys with client-side ECDH P-256 key
exchange. The server now only relays opaque public keys and encrypted
room key blobs — it never sees the actual room encryption key.
Protocol:
- voice_e2ee_announce: clients broadcast ECDH public keys
- voice_e2ee_offer: key holder wraps room key for each peer via ECDH+HKDF+AES-GCM
- Key rotation on participant leave (forward secrecy)
Server changes:
- Remove VoiceE2EEKeys (server-side key generation)
- Add relay handlers for announce/offer messages
- Store per-client ECDH public keys on Client struct
- Send existing public keys to new joiners during voice state sync
Client changes:
- New e2eeCrypto.ts: ECDH P-256, HKDF-SHA256, AES-256-GCM key wrapping
- LiveKitSession generates keypair on join, manages key holder election
- Key holder generates room key and wraps for each peer
- Non-holders wait for offer before connecting to LiveKit
- Room key rotated when any participant leaves
https://claude.ai/code/session_01KKo3RwjdmcNzkgXNfUkgNT
Server generates a per-channel 256-bit symmetric key (crypto/rand) when
the first participant joins voice. The key is distributed to all
participants via the voice_token WS message (already TLS-encrypted) and
cleared when the channel empties for forward secrecy per session.
Client configures LiveKit Room with ExternalE2EEKeyProvider and an
SFrame e2ee-worker. All audio/video frames are encrypted client-side
before reaching the SFU — the server never sees plaintext media.
Changes:
- Server: new VoiceE2EEKeys store, e2ee_key in voice_token payload
- Client: E2EE Room options, key provider wiring for connect/reconnect
- CSP: added worker-src 'self' blob: for the E2EE Web Worker
https://claude.ai/code/session_01KKo3RwjdmcNzkgXNfUkgNT
Add user_update event so other clients see profile changes in real-time
without needing to reconnect. Also updates saved credentials in Windows
Credential Manager when the current user changes their username.
Fixes: livekit-session test mock missing unpublishTrack property.
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.
Server: suppress errcheck on deferred Close() calls, discard
resp.Body.Close error, remove unused voiceSpeakersPayload type
and buildVoiceSpeakers func.
Client: add unit tests for os-motion, livekitSession, and
safe-render to bring coverage from 74.16% to 76.06% (threshold 75%).
Server:
- Fix YAML injection in LiveKit config generation (quote values)
- Revert token TTL to 4h (no server-side JWT revocation)
- Derive LiveKit publish permissions from user role (prevent SFU bypass)

- Add voice_leave broadcast to rollbackVoiceJoin (prevent ghost state)
- Limit webhook body to 64KB (prevent memory abuse)
- Add rate limit to voice_token_refresh handler (1/60s)
- Add LiveKit health check endpoint (GET /api/v1/livekit/health, 503 on degraded)
- Add voice_token_refresh WS handler for client-initiated token refresh
- Consolidate voice quality constants (single source of truth)
- Fix video limit TOCTOU race (count from DB instead of LiveKit API)
- Raise default voice_max_video from 10 to 25 (Discord parity)
- Add CountActiveCameras DB query
- Non-blocking broadcast send, circuit breaker, exponential backoff
- Close send channel before context cancel in serve.go
- Guard voice mute/deafen for active channel
- Delete orphaned message on attachment link failure
- Redact query string from proxy logs (prevent token leak)
- Use instance-level HTTP client for health checks (no redirect following)
- Set cmd.WaitDelay to prevent goroutine leak on Windows
- Log buildJSON marshal errors
Client:
- Refactor livekitSession.ts from singleton module to LiveKitSession class
- Share single AudioContext for all analysers (was 1 per participant)
- Extract createRoom() helper (DRY)
- Add token refresh timer (3.5h interval, re-arms on failure)
- Skip setSpeakers if unchanged (sort in-place, no allocations)
- Distinguish user-initiated leave from connection error in retry
- Add YouTube videoId validation (prevent iframe src injection)
- Add try/finally to disableCamera
- Wrap store subscription callbacks in try/catch
- Track and cancel initial scroll RAF on cleanup
- Add 5s timeout + encodeURIComponent to YouTube oEmbed fetch
- Clean raw mic stream on RNNoise suppressor failure
- Full voice cleanup on logout via cleanupAll()
Tests:
- Add 7 new server tests (webhook parsing, voice guards, quality fallback)
- Fix 2 pre-existing test failures (mute/deafen invalid payload)
Architecture:
- Add subscribeSelector to store.ts for selective state subscriptions
- Create reconcileList utility for DOM list patching without rebuild
- Create shared createContextMenu utility (dedup 3 files)
- Convert all 20 subscribe() calls to subscribeSelector across 11 files
- Split renderers.ts (1131L) into 7 focused files by concern
- Split ConnectPage.ts (838L) into ServerPanel + LoginForm + shell
- Fix ineffective (s) => s selector in ChannelSidebar
GIF visibility:
- Add media-visibility.ts with IntersectionObserver + canvas snapshots
- GIFs auto-pause after 10s, play/pause button overlay on hover
- Freeze GIFs on scroll-away, window blur, and minimize
- Wire into media.ts, attachments.ts, embeds.ts renderers
Tests: 46 new tests (1073 total), all passing
Net: -1166 lines across client codebase
