PendingVoiceJoin was missing the isKeyHolder field, so when the drain
loop called connectAndSetup for a queued join it defaulted to false,
entering the "wait for room key from key holder" E2EE path and hanging
indefinitely. Store isKeyHolder in the pending join and forward it.
- 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
Update LiveKitSession tests to use _state discriminated union instead of
old flat field names (room, currentChannelId, latestToken, etc.) removed
in the state machine refactor. Also fix renderers.test.ts URL resolution
by setting a server host in beforeEach so isSafeUrl can parse relative
attachment URLs in jsdom. Stage all four Go test files so the CI Go job
runs them.
Additionally fix a regression in connectAndSetup's finally block: when a
pendingJoin is queued during a stale-join abort, preserve the connecting
state so handleVoiceToken's drain loop can pick it up rather than losing
it by resetting to idle.
Periodic key rotation:
- Key holder rotates room key every 5 minutes for forward secrecy,
independent of participant changes. Timer managed by key holder only.
Offer retry mechanism:
- Non-key-holders re-announce their public key after 10s timeout and
wait 5s more before giving up. Covers lost offers from target
disconnect during async key wrapping.
- Key holder now re-sends room key offer on duplicate announces (peer
may be re-requesting after a missed offer), instead of ignoring them.
Key fingerprint verification:
- New computeKeyFingerprint() in e2eeCrypto.ts — SHA-256 hash of raw
public key formatted as "AB12 CD34 ..." for out-of-band verification.
Can be displayed in UI for MITM detection.
Server hardening:
- Public key size limit tightened from 256 to 128 bytes (P-256
uncompressed = 65 bytes = ~88 base64 chars).
Client hardening:
- WebCrypto availability check at module load — throws descriptive
error if crypto.subtle is unavailable (non-HTTPS context).
- base64ToUint8() now wraps atob() in try-catch with clear error message.

Critical fixes:
- C1: Key holder election now uses lowest-user-ID from voiceStore instead
of "am I first in peerPublicKeys" heuristic, preventing simultaneous
join race where both participants generate conflicting room keys
- C2: TOCTOU race in handleVoiceE2EEOffer — target channel check now
happens inside h.mu.RLock() section (atomically with client lookup)
- C3: Server now validates base64 encoding for public_key, encrypted_key,
and iv before relaying, preventing client-side DoS via malformed payloads
High fixes:
- H1: ECDH keypair regenerated on reconnect with fresh announce, so
stale keys don't persist and key rotation during disconnect is handled
- H2: E2EE epoch counter prevents stale offers from overwriting a
rotated room key (handleE2EEOffer discards if epoch changed during unwrap)
- H3: After key rotation, re-check for peers that arrived during the async
wrapping loop and send them the new key too
- H4: _ecdhKeyPair and _roomKey captured in local vars before async
operations to prevent null dereference if clearE2EEState runs concurrently
Medium fixes:
- M1: User notified via onErrorCallback when E2EE key exchange times out
- M2: Timeout timer properly cleared to prevent leak and unhandled rejection
- M3: Duplicate announces deduplicated — same key ignored, changed key logged
https://claude.ai/code/session_01KKo3RwjdmcNzkgXNfUkgNT
- Use deterministic key holder election (lowest user_id) instead of
Map insertion order which is not guaranteed to match join order
- Use parseUserId() instead of raw parseInt() for LiveKit identity parsing
- Add concurrent key rotation guard (_rotatingKey flag) to prevent
races when multiple participants leave in rapid succession
- Queue voice_e2ee_announce messages that arrive before ECDH keypair
is ready; drain after keypair generation in connectAndSetup
- Propagate decryption failures to roomKeyResolver so connectAndSetup
unblocks with an error instead of hanging
- Reject (not resolve) roomKeyResolver on voice leave for proper cleanup
- Convert dynamic await import("@lib/e2eeCrypto") to static imports
- Add VOICE_E2EE_ANNOUNCE/OFFER to protocolTypes.ts enum constants
- Use typed S.VOICE_E2EE_* constants in dispatcher instead of string casts
- Add payload size limits for encrypted_key (1024) and iv (128) on server
https://claude.ai/code/session_01KKo3RwjdmcNzkgXNfUkgNT
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

Restores dangerous-settings and allowSelfSigned which are required for
self-hosted servers with self-signed certificates. Makes HealthResponse.version
optional to match server-side removal, and updates router tests to assert
version is correctly omitted from unauthenticated endpoints.
https://claude.ai/code/session_01KKo3RwjdmcNzkgXNfUkgNT
Addresses 14 findings from the security audit across all severity levels:
CRITICAL:
- C-1: Add user blocking system (migration, DB queries, REST API, WS DM
send check) to prevent harassment via unconsented DMs
- C-2: Remove server version from unauthenticated /health and /info endpoints
to prevent fingerprinting
HIGH:
- H-1: Remove dangerous-settings feature from tauri-plugin-http
- H-3: Default allowSelfSigned to false in API client (was hardcoded true)
- H-4: Cap invite expiration to 30 days (720 hours)
- H-5: Add 256KB message size limit to LiveKit WS proxy (prevents OOM)
- H-6: Cap concurrent sessions to 25 per user (evicts oldest on overflow)
- H-8: Restrict /diagnostics/connectivity to ADMINISTRATOR role
MEDIUM:
- M-2: Deny access to legacy NULL-uploader unlinked attachments
- M-4: Log warnings on TOTP plaintext decryption fallback paths
- M-8: Remove acceptInvalidCerts from OG preview fetches
- M-10: Expand file upload blocklist (Java .class, OLE2, WASM, .lnk)
- M-12: Add LIMIT to ListInvites (200) and ListMembers (1000)
- M-14: Add CHECK constraint trigger on channels.type (text/voice/dm)

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

- Gate DevTools button and F12/Ctrl+Shift+I shortcut behind import.meta.env.DEV
- Disable devtools Tauri feature in production (Cargo.toml default feature removed)
- Remove overly broad http:default capability, replace with scoped http:allow-fetch
- Set withGlobalTauri to false to avoid global __TAURI__ surface exposure
- Fix reconnect race: add abort checks after room creation, URL resolve, and connect (BUG-070)
- Fix ws.ts reconnect guard: bail out safely when config is null after disconnect
- Fix DM broadcast double-send and add monotonic seq + replay buffer support via sendSequencedToUsers
- Add seqMu mutex to serialize seq assignment across broadcastDM and deliverBroadcast paths
- Fix handleFreshConnect to unregister client and close connection on buildReady failure
- Add tests for PTT allowlist, ws reconnect config-null guard, livekit abort-after-connect, and DM sequencing
- Fix typo in setup-buildx-action pin (d8db...→d36ec...) that caused CI to fail
- Replace stale TenorGif type with GifResult in gif-picker.test.ts lines 531-532
Client:
- Replace Win32 Credential Manager with cross-platform keyring crate
(Windows Credential Manager / Linux Secret Service / macOS Keychain)
- Add Linux PTT support via device_query crate with VK-code-compatible
mapping; thread-local DeviceState avoids repeated /dev/input/ opens
- Add AppImage + deb bundle targets to tauri.conf.json with Linux
metadata and deb runtime dependencies
Cargo.toml:
- Add keyring = "3" (all platforms)
- Add device_query = "2" (Linux only, cfg guard)
- Remove Win32_Security_Credentials feature (no longer needed)
CI/CD:
- Add ubuntu-22.04 and ubuntu-22.04-arm to tauri-build matrix
- Fix Linux deps step condition: startsWith(matrix.os, 'ubuntu')
- Add server Docker build verification job (build-only, no push)
- Add release-client-linux (x86_64) and release-client-linux-arm64
jobs producing AppImage + deb artifacts
- Add release-server-docker job pushing to ghcr.io on version tags
- Update publish job to include all Linux and ARM64 artifacts
Server:
- Add multi-stage Dockerfile (golang:1.25-bookworm → distroless/static)
- Non-root user (uid 65532), /app/data volume, port 8443 exposed
- Add .dockerignore excluding binaries, data, and local config
Tenor shuts down June 30, 2026. Klipy is a drop-in replacement built
by the ex-Tenor team, free for production use.
- Replace tenor.ts with gifProvider.ts (api.klipy.com/v2)
- CDN allowlist updated to *.klipy.com (static.klipy.com is the real CDN)
- Add Klipy watermark logo to sent GIFs in chat (bottom-left)
- Update attribution text to "Powered by Klipy"
- Wire VITE_KLIPY_API_KEY secret into release workflow
- Add .env to .gitignore to protect local API key
- updater.go: DownloadAndVerify now uses parseChecksumFileAny with
checksumEntryNamesForGOOS so the linux/ path prefix produced by the
release workflow's sha256sum is found correctly (fixes
TestDownloadAndVerify_Success on ubuntu-latest)
- video-grid.test.ts: add setScreenshareAudioVolume to the
@lib/livekitSession mock so vitest does not throw on the export
that VideoGrid.ts imports
- ci.yml: add top-level `permissions: contents: read` to restrict
GITHUB_TOKEN to minimum required (fixes 3 missing-workflow-permissions alerts)
- claude-code-review.yml: remove unsafe `ref: pull_request.head.sha`
checkout in pull_request_target workflow and pin checkout to SHA
(fixes untrusted-checkout/high alert)
- tenor.ts: add codeql suppression comment for hard-coded-credentials;
the fallback key is Google's public anonymous demo key, not a secret
- Consolidate ws-state and cert-tofu emit calls in ws_proxy.rs into
private helper functions (emit_ws_state, emit_cert_tofu). One call
site per event name prevents tauri-typegen 0.5.0 from generating
duplicate event listener functions.
- Add CI fixup step that injects 'export type Value = unknown' into
generated types.ts — tauri-typegen cannot map serde_json::Value to
a TypeScript type, so the generated file references an undefined type.

- Add validateAvatarURL helper enforcing https:// scheme, non-empty host, and 512-char max length
- Add rate limiting (10/min) to PATCH /api/v1/users/me profile update endpoint
- Guard avatar rendering in DmSidebar, DmProfileSidebar, and UserProfilePopup with isSafeUrl check to prevent unsafe URL injection in the UI
Update golangci-lint-action to v9.2.0 with correct commit SHA. Change
eslint-disable-next-line to oxlint-disable-next-line for oxlint-specific
rules (consistent-function-scoping, prefer-add-event-listener,
require-post-message-target-origin) that ESLint doesn't recognize.
Soundboard was never implemented — remove USE_SOUNDBOARD permission bit,
rate limiter, protocol entry, admin mockup reference, TODOS entry, and
all related test assertions.
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.
The client was sending DELETE /api/v1/invites/{id} with a numeric database
ID, but the server expects the invite code string. This caused a 404 since
no invite has a code matching a numeric ID.
Both setupAudioPipeline and teardownAudioPipeline called replaceTrack
as fire-and-forget. If teardown's replaceTrack resolved after setup's,
the WebRTC sender would be bound to the wrong track. Both paths now
capture _pipelineGeneration before the async call and detect stale
completions, preventing out-of-order track replacement.
BUG-107: cleanupAllAudioElements now calls pause() and sets
srcObject = null before removing elements from DOM, ensuring streams
are fully released during reconnection cleanup.
BUG-121: Diagnostics endpoint now has 5 req/min rate limit as
documented, preventing enumeration of internal topology.
BUG-132: DeleteOrphanedAttachments uses DELETE ... RETURNING stored_as
(atomic) instead of separate SELECT then DELETE, eliminating the race
where a file could be deleted after its attachment was linked.
Refine auto-open to match Discord behavior: grid opens automatically
when the local user enables camera or screenshare, but NOT when remote
users do. Remote video requires clicking the user row to open.
BUG-105: checkVideoMode now auto-opens the video grid when any video
stream (local or remote camera/screenshare) becomes active. Previously
tiles were added to a hidden grid container.
BUG-139: All GitHub Actions pinned to commit SHAs instead of mutable
tags. Tool installs (govulncheck, tauri-typegen, cargo-audit) pinned
to specific versions instead of @latest.
BUG-099: Auto-reconnect now reapplies saved audio input/output devices
via switchActiveDevice, matching the initial join path.
BUG-102: Screenshare tile volume slider now calls
setScreenshareAudioVolume with the normalized value instead of only
toggling mute. Intermediate volumes (e.g. 50%) work correctly.
BUG-104: attachScrollCollapse moved from update() to component creation
so only one listener is attached to the container, preventing
accumulation on every voice state change.
BUG-100: Camera/screenshare tracks are now stopped in catch blocks when
publishTrack fails, releasing hardware immediately.
BUG-101: Screen video track now has an 'ended' listener that triggers
the full disableScreenshare flow when the OS "Stop sharing" button is
clicked, keeping UI and WS state in sync.
BUG-103: retryMicPermission now checks localDeafened state. If deafened,
the mic is acquired but kept muted so audio is not published while the
UI shows deafened.
wirePostAuth always called saveCredential regardless of the "Remember
password" checkbox state, leaving the session token in Windows
Credential Manager even when the user opted out. Added rememberPassword
parameter to wirePostAuth and skip saveCredential when false.
teardownForReconnect only cleaned up audio pipeline and token timer,
leaving manual camera/screenshare MediaStreamTracks capturing
indefinitely after unexpected disconnect. Added stopManualCameraTrack
and stopManualScreenTracks calls before room is nulled, plus store
flag resets so the UI reflects the actual state.
The cert-tofu event listener now handles "trusted_first_use" status
and shows a visible notification banner with the server hostname and
SHA-256 fingerprint. Adds onCertFirstTrust callback to the WS client
API. First-use certificate trust is no longer silent.
Replace danger_accept_invalid_certs(true) with PinnedVerifier-based
rustls config that validates server cert against TOFU fingerprint from
the cert store. For CA-signed servers (no stored fingerprint), system
TLS is used. Shared PinnedVerifier, cert_store_key, and
load_stored_fingerprint are now pub(crate) for reuse.
