Added federation_peers_changed (no-payload signal) broadcast from every
peer state mutation, and federation_approval_request_received when a new
approval request is queued. Client subscribes via onFederationPeersChanged
callback registry. FederationPanel and PendingApprovals debounce-refetch
on any event. sendToAdmins helper broadcasts only to admin users.
The client's direct WS connection to remote instances (via Connections)
delivered DM events independently of S2S peering. Added activePeerOrigins
allowlist to ready payload — all DM event handlers now silently drop
events from non-home origins without an active peer. This prevents
notifications, sounds, previews, typing indicators, calls, and channel
updates from instances where peering was revoked or never established.
sendToFederatedCallUsers sent dm_call_ended/rejected back to the user
who initiated the action. They already disconnected in their click
handler — the redundant event triggered disconnectFn() again, causing
connect and disconnect sounds to play simultaneously.
Added excludeUserId parameter to sendToFederatedCallUsers, used in
handleDmCallEnd and handleDmCallReject Path 2.
Root cause: sendToFederatedCallUsers used sendToDmMembers when dmChannelId
was set, which broadcast to ALL DM members including the caller's replicated
stub. The caller's multi-instance WS received dm_call_accepted with the
REMOTE instance's dmChannelId, causing token request for a non-existent
channel (403) and preventing the caller from connecting.
Fix 1: sendToFederatedCallUsers always uses ringedUserIds (exact recipients)
instead of sendToDmMembers (all members including caller stub).
Fix 2: dm_call_accepted handler only sets activeDmCall if the client is the
caller (wasOutgoingCall) or already connected to LiveKit. Other instances of
the same user just clear ringing without entering stuck "Connecting..." state.
When a federated user first accesses DMs on a remote instance,
all channels appear unread because no read_states rows exist.
Seed missing read states to the latest message during the ready
payload build. The S2S relay keeps things in sync going forward.
Aligns the ready payload query with the GET /api/dm approach:
get MAX(created_at) per channel first, then fetch the actual
message rows. Avoids issues with federated relay messages whose
local snowflake IDs don't match chronological order.
- Resolve homeUserId from DB in sendFederatedCallStart/End (not raw userId)
- Clear existing timeout in createFederatedCall before overwriting
- Clear federatedCallToken/Url in leaveVoice and handleForceDisconnect
- Remove unnecessary `as any` cast in relay processor
The buildReadyPayload query fetched all dm_members rows without
checking the closed flag, causing closed DMs to reappear on every
page reload. The REST endpoint GET /api/dm already filtered correctly.
Federated relay messages can have local snowflake IDs that don't match
chronological (createdAt) order — a message sent earlier on a remote
instance can arrive later and get a higher local ID. This caused a
permanent mismatch between the ready event's lastMessage (MAX id) and
the acked message (last in createdAt display order), making federated
DM channels appear unread after every server restart.
- Server: change ready event DM lastMessage query from MAX(id) to
ORDER BY created_at DESC (matching the DM REST API)
- Frontend: change ackChannel to ack MAX(id) among loaded messages
instead of last in display order (consistent with server comparison)
- Fix federated username display fallback in UserDiscoverCard
Replace the hard-delete in the leave handler with a soft-delete (sets
deleted_at timestamp) when the last member leaves a group DM. A new
janitor sweep in the federation worker runs hourly and purges channels
whose grace period has expired, cascading through reactions, embeds,
attachments, messages, members, outbox/mutation-log/file-queue entries,
and finally the channel itself.
All client-facing dm_channels queries now filter on deleted_at IS NULL
to hide soft-deleted channels from the REST API and WebSocket ready
payload.
Previously, voice cleanup only happened in finalizeDisconnect after a
5-second grace period, and only when ALL connections closed. If a user
was logged in on multiple devices and closed the one in voice, the
voice state was never cleaned up — creating a permanent ghost in the
channel sidebar.
Now removeConnection checks if the closing socket is the voice-active
one (tracked via voiceWs map) and immediately cleans up voice state,
broadcasts the leave event, and notifies remaining tabs.
Add Rich Presence infrastructure to ConnectionManager:
- Four new Maps: userActivities, userShowActivity, userStatuses, lastActivityUpdate
- Public accessors: set/get/clear activities, showActivity, status, rate limit check
- Cleanup in finalizeDisconnect() and forceDisconnectUser()
- Cache showActivity and status from DB at auth time in buildReadyPayload()
- Assemble userActivities snapshot in ready payload with customStatus fallback
- Include activities: [] in offline presence_update broadcast
- Add Activity, ActivityType, ActivityTimestamps, ActivityAssets types to shared types
- Add activity_update client event and activities field on presence_update server event
- Add userActivities to ready payload and showActivity to User/UpdateUserRequest
- Create shared activities.ts with ACTIVITY_LIMITS, ACTIVITY_PRIORITY, getPrimaryActivity
- Add show_activity column to users table (schema + migration)
- Update sanitizeUser with isSelf parameter; only include showActivity for self
- Fix .map(sanitizeUser) calls to use arrow wrapper to prevent index-as-boolean bug
- Mark auth routes (register/login) as isSelf=true since they return own user data
- SSRF protection: DNS resolution + private IP blocking on metadata fetcher
- Upload security: CSP/X-Frame-Options headers, SVG forced download, nosniff
- Auth hardening: JWT secret min length, password min 8 chars, token revocation via password_changed_at
- Attachment ownership verification before linking to messages
- Message length limit (4000 chars) enforced on client and server
- Asset URL validation on avatar/banner updates
- Federation instance validation (domain regex, origin scheme, length limits)
- DB indexes on all FK columns for query performance
- Migrations: nullable moderator columns, dm_messages reply_to FK constraint
- File cleanup on avatar/banner replacement and space deletion
- Fastify trustProxy, AbortController on fetches, typing map size cap
- Rewrite ChannelSettingsModal with full tri-state permission override UI
for roles and members (allow/neutral/deny per permission bit)
- Switch font from Inter to self-hosted DM Sans (woff2 variable fonts)
- Add client-side VIEW_CHANNEL filtering in ChannelSidebar for private channels
- Broadcast isPrivate flag on channel override changes
- Fix voice permission bit migration: gate behind persistent flag to prevent
repeated re-runs that stripped STREAM from @everyone roles
- Add speakingUserIds set to voice store for efficient user-level lookups
- Clear current channel view when a channel is deleted
- Move .glass-strip to @layer utilities for proper CSS specificity
- Simplify avatar initials font size to proportional formula
Profile and space layout changes on remote instances were being
overwritten by stale data on reconnect. Adds Last-Writer-Wins
timestamps so the client-relay mesh rejects stale writes:
- profile_updated_at column on users table with migration + backfill
- Server LWW guards on PATCH /users/@me and PUT /space-layout
- Bidirectional profileSync: pulls newer remote profiles to home
- LWW layout sync replaces home-authoritative _layoutFromTrueHome flag
- Layout pushes to ALL connected instances in parallel
Add user_space_layout table and PUT /api/users/@me/space-layout endpoint
for persisting per-user sidebar ordering. Spaces can be freely reordered
via drag-and-drop, folders created by dragging one space onto another,
and folders auto-dissolve when they have fewer than 2 members. Includes
folder context menu (rename, color, ungroup), collapsed folder mini-grid
icons, multi-tab sync via WebSocket, and localStorage collapse state.
Removes the rigid native/federated split — federated spaces now intermix
freely while keeping their globe badge.
Voice channels already support video/screen share, so the separate video
type was redundant. Adds migration to convert existing video channels.
Also adds border-border-soft to CreateChannel input fields for visibility.
Add avatarColor field to spaces, matching the user avatar color system.
Spaces get a random color on creation and owners can change it in space
settings. The color controls the fallback gradient when no icon is uploaded,
replacing the old deterministic hash-based gradient. Includes full
federation support, explore page, mutual spaces, and color picker in both
create and settings modals.
- Add account deletion with tombstone (isDeleted flag), password/username
confirmation, owned-space guard, and full cleanup transaction
- Free deleted usernames by renaming to !deleted:<id> so they can be reused
- Add migration to retroactively free usernames from already-tombstoned users
- Add GET /api/auth/check-username endpoint with rate limiting for real-time
availability checking during registration
- Add debounced username availability indicator on registration Step 1
- Add DeleteAccountModal with federation-aware remote account cleanup
- Add federation ops utility for remote instance management
- Update sanitizeUser to anonymize deleted user profiles
- Add instance store improvements and connected instances modal updates
Add server-side heartbeat using RFC 6455 protocol-level ping/pong frames
to detect abruptly disconnected clients (e.g. PC shutdown without TCP FIN).
Dead connections are terminated within ~65s, triggering the existing
cleanup chain to remove ghost users from voice channels and presence.
Permission changes now take effect immediately without requiring
disconnect/reconnect. Modeled as "permission mute" parallel to
server mute — server recomputes SPEAK for all voice participants
on role/override changes and broadcasts state via WebSocket.
Includes amber UI indicators and mic toggle blocking.
- Replaces global `userId` tracking with `spaceId:userId` composite keys across both backend and frontend, fixing the issue where server-muting a user in one space bled into others.
- Modifies client-side `ready` event hydration to merge voice states per-origin instead of completely overwriting the store, preventing federated connections from wiping out home instance mutes.
- Excludes server voice restrictions from `zustand/persist` so stale client caches don't override the server's authority on reload.
- Fixes React component reactivity by using reactive store selections for `spaceId` instead of imperative `getState()` calls, ensuring UI lockdown indicators accurately reflect the initial websocket handshake.
- Client ready handler now builds restriction Sets atomically in a single
setState call, eliminating intermediate empty-Set state that caused amber
icons to flash rose on reload
- buildReadyPayload queries all voice restrictions from DB across the
user's spaces instead of relying on in-memory state (which is lost on
disconnect timeout)
- voice_join early-return path now re-broadcasts restrictions to the
reconnecting user, covering fast reload where the user is still in the room
Server-side: add DB persistence for voice restrictions (schema, migration,
ready payload, cleanup on leave). Client-side: fix four bugs that wiped or
bypassed server restriction state — leaveVoice() no longer clears global
restriction Sets, voice_state_update leave no longer drops amber icons,
toggleMic/toggleDeafen now guard against server restrictions, and force-mute/
deafen uses direct setState instead of fragile toggle calls.
Add ban/unban functionality with BansPanel in space settings, voice
moderation context menu (mute/deafen/disconnect), and fix federated
space settings panels to use origin-aware API client. Show domain
indicators for federated members in MembersPanel.
- Redesign explore cards with banner images, overlapping icons, and frosted fade
- Extract dominant colors from space icons for dynamic banner gradients
- Add space description/banner fields to schema with migration
- Move origin label from banner overlay to content metadata row
- Support space descriptions in settings overview panel
- Fix DM welcome header avatar using home identity for correct gradient color
- Register DM channel IDs in channelOriginMap so federated DM operations
(reactions, messages, typing) route to the correct instance
- Pass origin when creating DM channels from friends list and WS events
- Add server discovery/explore page with public server listings
- Add server visibility and description fields
Add multi-instance support foundation: shared federation types
(ReplicatedInstance, InstanceInfoResponse, VerifyPasswordRequest),
database schema changes (home_instance, replicated_instances on users,
instance_name on settings), public instance info endpoint, auth
registration with homeInstance and username@domain collision fallback,
password verification endpoint, and replicatedInstances sync on user
profile. Extract duplicated sanitizeUser into shared utility across
8 server files.
- Add Backspace-design-prototype.html: finalized "Aether Drift" design
language with warm matte surfaces and subtle frosted glass accents
- Update CLAUDE.md with DESIGN SYSTEM section and remove Discord clone references
- Rename all Opencord references to Backspace across the full codebase
- Archive outdated design experiments and Discord-specific assets
- Add science-backed accessibility fallback (prefers-reduced-transparency)
Add a server-side instance_settings table (single-row, CHECK(id=1))
that stores admin-configurable streaming bounds: bitrate min/max/step,
allowed resolutions, and allowed framerates.
Backend:
- New instance_settings schema + migrations (is_admin on users, default
settings row, first-registered-user promoted to admin)
- GET/PATCH /api/settings/streaming endpoints with admin-only writes
and full input validation including cross-field checks
Frontend:
- settingsStore fetches limits on WebSocket ready, exposes isAdmin flag
- ScreenShareSettingsPopover reads bounds from store instead of
hardcoded constants, auto-clamps stale localStorage values
- buildScreenShareOptions() clamps bitrate to server limits at build
time as enforcement backstop
- ServerSettings modal gains a "Streaming" tab (admin-only) with
bitrate range sliders, resolution/framerate toggles, and save/reset
Remove the legacy TEXT role column ('owner'/'admin'/'member') from
server_members and make the bitwise RBAC member_roles junction table
the sole authority for role assignments. Owner detection now uses
servers.ownerId exclusively.
- Remove MemberRole type and role field from shared types
- Remove role from Drizzle schema, raw SQL CREATE TABLE, and seed data
- Rewrite PATCH /members/:uid to accept { roleIds: string[] }
- Fix GET /members to populate roles array (was TODO)
- Replace member.role === 'owner' guard with isServerOwner()
- Remove getMemberRole() helper and legacy bridge code
- MemberSidebar groups by highest-positioned role instead of legacy string
- ServerSettings replaces admin/member dropdown with role checkboxes
- Message.tsx derives color from roles[] with owner fallback via ownerId
- Existing DBs keep vestigial column (Drizzle ignores it); new DBs omit it
Wire the bitwise permission engine end-to-end:
- Add sendToChannel() to ConnectionManager, filtering WS recipients by VIEW_CHANNEL
- Convert 6 channel-scoped events (messages, typing, reactions) from sendToServer to sendToChannel
- Add broadcastOverrideChange() to push channel_updated/channel_deleted per-user on override mutations
- Bridge legacy server_members.role TEXT to member_roles junction table on PATCH
- Add pushReadyPayload() to force re-sync frontend store after role changes
- Filter channels by VIEW_CHANNEL in GET /api/servers/:id to prevent initial load data leak
- Pre-compute viewers before CASCADE delete on channel_deleted
- Fix frontend channel event handlers to upsert/cleanup channelToServerMap and channelPermissions
- Add ChannelSettingsModal with Private Channel toggle and gear icon in ChannelSidebar
