Store the original home snowflake ID (homeUserId) during federation replication
so that avatar gradient colors resolve identically across instances. Previously,
replicated users got new snowflake IDs on each instance, causing different
gradient colors. Now Avatar, UserProfilePopout, VoiceUser, StreamTile, and
VoiceChannel all resolve through homeUserId when available. Includes backfill
logic for existing federated users missing the field.
Add identity.ts with isSelf() and resolveDisplayIdentity() — pure
stateless functions that detect replicated-self using the immutable
(username, homeInstance) composite key. No store lookups, no data
mutation. Fixes wrong avatar gradient and missing edit/delete on
own messages in remote channels.
Also includes: optimistic message dedup fix for cross-instance
messages (content-only matching), federation toast notifications,
Username component with @domain display, invite parser, and
deploy script simplification.
Batch 1 — Bug fixes:
- Fix stale voice state on remote reconnect (clearVoiceUsersForOrigin)
- Fix logout not cleaning remote servers from store
- Fix reply-to asset normalization for remote messages
- Fix HTTPS hardcoded in autoConnectAll (store full origin, legacy fallback)
Batch 2 — Password enforcement + replication flow:
- Add connectToRemote() with home password verification before remote auth
- Auto-cascade: verify home password → register on remote → login fallback
- Replace Register/Login tabs with single password field in ConnectedInstances
- Add DifferentPasswordError for typed fallback-login UI transition
- Fallback login form shown only when remote has different password
Redesign deployment as a single docker-compose with Backspace, Caddy
(auto-HTTPS), and LiveKit (voice/video) using hybrid networking:
Backspace+Caddy on isolated bridge, LiveKit on host mode for WebRTC.
- Add install.sh: interactive installer that handles Docker setup,
domain/DNS verification, secret generation, LiveKit config, and
deployment with health-check wait
- Add Caddyfile: static reverse proxy config using Caddy env vars,
routes /livekit/* to host-mode LiveKit via host.docker.internal
- Rewrite docker-compose.yml: all-in-one with profiles (voice),
no external volumes/networks, bind mount ./data for visibility
- Fix livekit.ts: use LIVEKIT_URL env var directly instead of
Host-header derivation that made the env var dead code
- Fix Dockerfile: health check reads $PORT dynamically
- Update .env.example: add DOMAIN, COMPOSE_PROFILES documentation
- Update .gitignore: add livekit.yaml (contains secrets)
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
Replace string-based role checks (role === 'admin') with a bitwise BigInt
permission system. Adds computePermissions() resolution engine following
Discord's model: @everyone base → role union → admin shortcut → channel
overrides (role deny/allow → member deny/allow). Ready payload now filters
channels by VIEW_CHANNEL and attaches per-user myPermissions to each
server and channel. Includes channel_overrides table, @everyone role
auto-creation, migration for existing servers, and override CRUD API.
Wrap all multi-write DB operations in atomic transactions (server/channel
creation, message+attachment linking, DM creation, friend acceptance,
cascading deletes) to prevent partial-write corruption.
Batch N+1 queries in WS ready payload into O(1) bulk fetches with
chunked inArray() to respect SQLite's variable limit.
Fix chat history regression where background WS messages bypassed
channel load by switching the guard from messages.has() to hasMore.has().
Add LRU channel eviction (20 cached, evict to 15) and per-channel
message cap (200) to bound client memory growth.
Shorten WS heartbeat from 30s to 15s for aggressive proxy/NAT
environments. Clear all user-scoped stores on logout to prevent
cross-session data leaks.
Extract LiveKit internal accessors into shared livekitInternals utility.
DM uploads silently failed because the 5-point chain (types, frontend,
POST, GET, WS broadcast) was never wired for attachments. Added
buildDmMessageWithUser/getDmMessageWithUser helpers mirroring the server
channel pattern, and plumbed attachmentIds + replyToId through all DM
code paths.
Unlock group DMs by removing the 2-member assumption across the stack.
No schema migration needed — dm_members junction table already supports
N members. Includes dedup bug fix, add/leave member endpoints, late-join
call support, group-aware sidebar rendering, and AddDmMemberModal.
- Redesign DM close as a visibility flag (closed column) instead of row deletion,
so message broadcasts still reach users who closed a DM conversation
- Add broadcastDmMessage() helper that auto-resurfaces closed DMs when new messages arrive
- Wire Remove Friend button in DM welcome header with onClick handler and friend check
- Fix deploy.sh to cd to its own directory so rsync always runs from project root
- Add WS events: dm_channel_created, dm_channel_closed, friend_removed,
channel_created/updated/deleted, server_updated
- Fix first-ever DM: broadcast dm_channel_created to recipient
- Add DELETE /api/dm/:id for closing DMs with re-open support
- Wire Close DM button in sidebar
- Fix dm_message_created for unknown channels (safety net)
- Broadcast friend_removed on friend deletion
- Sound system: track realtimeMessageEvents separately from API loads,
play notification for messages in all channels, not just current
- Optimistic updates: send/edit/delete messages appear instantly with
rollback on failure, temp message deduplication on WS echo
- Channel CRUD broadcasts to all server members
- Server update broadcast on PATCH
- Server join registers user in connectionManager immediately
- Reconnect: only reload current channel, preserve other channel caches
- Activity panel, right panel, member list toggle components
- Implemented 'Overdrive' logic to force high bitrates on Chrome
- Fixed 'Auto' preset to default to stable 720p60
- Added persistent 'Triple-Kick' hammer to prevent bitrate throttling
- Fixed sidebar connection status sync
- Added comprehensive diagnostic logger
Phase 1 - Feature Repair:
- Fix member kick/leave: add missing db.delete() call in servers.ts
- Stabilize invite codes: return existing code instead of regenerating
- Fix user search: use LIKE instead of exact match in social.ts
- Wire DM button on FriendsPage to create/navigate to DM channels
- Add cancel outgoing friend request (DELETE endpoint + frontend)
- Add accept/decline friend request actions with WS real-time events
- Fix replyToId persistence in message creation
- Hydrate reactions and replyTo in message queries
- Add joinByCode to API client and serverStore
- Add friend_request_received/accepted WebSocket events
Phase 2 - Discord UI Overhaul:
- Remove stray borders between layout columns
- Replace shadow-sm with shadow-header on content headers
- Replace all bg-gray-*/text-gray-* with Discord color tokens
- Ensure flat color contrast (#1E1F22, #2B2D31, #313338)
Testing:
- Set up vitest + @testing-library/react + jsdom
- Add 17 tests across InviteModal, JoinServer, FriendsPage (all passing)
- Fix vite resolve.extensions to prefer .tsx over stale .js files
