Infrastructure + +**What:** Add E2E test infrastructure for voice flows (voice_join → LiveKit connect → audio → voice_leave). +**Why:** The voice path is critical UX with zero automated E2E coverage. Unit tests cover handlers and controllers, but nothing tests the full integration. +**Pros:** Catches integration bugs between server + LiveKit + client. +**Cons:** Requires LiveKit binary in CI, WebRTC support in test browser, ~200 lines of test infra. +**Context:** The existing native E2E infrastructure (WebView2 CDP) could be extended. Needs CI setup first. +**Depends on:** LiveKit binary available in CI environment. +**Added:** 2026-03-21 (eng review of feature/livekit-migration) + +## Voice Session Metrics + +**What:** Add voice session count and duration metrics to the /metrics endpoint. +**Why:** No way to know how many voice sessions happen or how long they last without reading logs. Useful for understanding usage patterns and catching degradation. +**Pros:** Visibility into voice health (shorter sessions = potential problem). +**Cons:** Requires tracking join/leave timestamps in memory (~10 LOC). +**Context:** /metrics already has connected users and LiveKit health. This adds voice-specific counters. +**Depends on:** /metrics endpoint (already implemented). +**Added:** 2026-03-22 (CEO review of feature/livekit-migration) + +## Create DESIGN.md + +**What:** Run /design-consultation to generate DESIGN.md from the existing tokens.css and ui-mockup.html. +**Why:** The 114-token design system exists in CSS but the reasoning, usage guidelines, and component vocabulary aren't documented. Future contributors (including AI) will guess which tokens to use. +**Pros:** Prevents design drift, makes the design language explicit, helps AI tools generate consistent UI. +**Cons:** ~15 min CC time. Must be kept up-to-date as tokens evolve. +**Context:** tokens.css was extracted from ui-mockup.html. Discord-inspired dark theme with Windows-first typography (Segoe UI Variable). +**Depends on:** feature/livekit-migration merged to main. +**Added:** 2026-03-22 (design review of feature/livekit-migration) + +## Extract AudioPipeline Class + +**What:** Extract ~200 lines of audio pipeline code (setupAudioPipeline, teardownAudioPipeline, VAD polling, volume control) from LiveKitSession into a separate AudioPipeline class in audioprocessing.ts. +**Why:** livekitSession.ts is 837 lines (exceeds 800-line max). The audio pipeline is independently testable but currently untested because it's entangled with session lifecycle. This is also a prerequisite for AudioWorklet migration. +**Pros:** Brings livekitSession.ts under 800 lines, enables independent testing, cleaner separation of concerns. +**Cons:** Requires careful interface design between LiveKitSession and AudioPipeline (~30 min CC). +**Context:** The audio pipeline was the source of prior regressions (commits c496f83, d498e8f). Extracting it makes both testing and future AudioWorklet migration easier. +**Depends on:** Nothing — can be done immediately. +**Added:** 2026-03-26 (eng review of feature/livekit-migration) + +## Audio Pipeline + Event Handler Tests + +**What:** Write unit tests for setupAudioPipeline, VAD polling, teardownAudioPipeline, and Room event handlers (TrackSubscribed, TrackUnsubscribed, Disconnected, ActiveSpeakersChanged) using AudioContext mocks. +**Why:** These are the most regression-prone codepaths with zero test coverage. Audio pipeline bugs caused two prior fix commits on this branch. +**Pros:** Catches regressions in the most bug-prone voice code. Enables confident refactoring. +**Cons:** Requires AudioContext mock infrastructure (~50 lines of test setup). +**Context:** The public API of LiveKitSession is well-tested (~80%), but the internal audio processing and event handling is entirely untested. +**Depends on:** AudioPipeline extraction (above) — tests will be much cleaner against the extracted class. +**Added:** 2026-03-26 (eng review of feature/livekit-migration) + +## HTTPS Proxy Unit Tests + +**What:** Add unit tests for the LiveKit HTTPS proxy (livekit_proxy in API package) covering WebSocket upgrade detection, header/subprotocol forwarding, bidirectional copy, and error paths. +**Why:** The proxy is the critical path for all non-localhost voice connections. A broken proxy means voice doesn't work for remote clients. +**Pros:** Validates the proxy works correctly for WebSocket upgrades and data forwarding. +**Cons:** Requires httptest-based WebSocket test setup (~100 lines). +**Context:** The proxy terminates TLS and forwards to LiveKit's local WebSocket port. It's used when clients connect over HTTPS (non-localhost). +**Depends on:** Nothing — can be done immediately. +**Added:** 2026-03-26 (eng review of feature/livekit-migration) + +## Migrate VAD to AudioWorklet + +**What:** Move voice activity detection from requestAnimationFrame polling on the main thread to an AudioWorklet running on the audio thread. +**Why:** rAF pauses when the browser/Tauri window is backgrounded — VAD stops working, mic stays stuck in its last gated/ungated state. For a gaming chat app, the window is often backgrounded. AudioWorklet runs independently of the main thread and tab focus. +**Pros:** VAD works correctly when app is backgrounded. Zero main-thread CPU cost. Proper architecture for audio processing. +**Cons:** Requires separate AudioWorklet JS file, MessagePort communication, more complex setup (~300 lines total). +**Context:** Current VAD polls at ~60 FPS via rAF (3-7x more than needed). AudioWorklet can process every audio frame natively. This is the industry-standard approach for browser audio processing. +**Depends on:** AudioPipeline extraction (above) — AudioWorklet replaces the VAD polling inside the extracted class. +**Added:**

Server operator runs `chatserver.exe` on their PC or home server +2. On first run, `config.yaml` is auto-generated with sane defaults +3. SQLite database is created and migrations are applied automatically +4. TLS certificates are generated (self-signed by default) +5. Friends download and install `OwnCord.exe` (the Tauri v2 client) +6. Client connects to the server via `wss://server-ip:port/api/v1/ws` +7. All chat, voice, video, and file transfers go through the server +8. Admin manages the server through a browser at `https://server-ip:port/admin` + +--- + +## Go Package Map + +```text +Server/ ++-- main.go # Entrypoint: config, DB, router, server lifecycle ++-- config/ +| +-- config.go # YAML + env config loading via koanf ++-- auth/ +| +-- auth.go # Package declaration +| +-- session.go # Token generation (256-bit random) and hashing (SHA-256) +| +-- password.go # bcrypt hashing (cost 12), validation, timing-safe compare +| +-- helpers.go # ExtractBearerToken, IsEffectivelyBanned, IsSessionExpired +| +-- ratelimit.go # In-memory sliding-window rate limiter with lockout +| +-- tls.go # TLS certificate loading/generation (self-signed, ACME, manual) ++-- db/ +| +-- db.go # SQLite open, WAL mode, pragmas, connection setup +| +-- migrate.go # Schema migration runner (embedded FS, version tracking) +| +-- models.go # Go structs: User, Session, Channel, Message, Role, etc. +| +-- errors.go # Sentinel errors: ErrNotFound, ErrForbidden, ErrConflict, ErrBanned +| +-- auth_queries.go # User CRUD, session CRUD, status updates +| +-- channel_queries.go # Channel CRUD, permission overrides, read states +| +-- message_queries.go # Message CRUD, FTS5 search, reactions, pins +| +-- voice_queries.go # Voice state join/leave/update, camera/screenshare counts +| +-- role_queries.go # Role CRUD, hierarchy management +| +-- invite_queries.go # Invite code CRUD, atomic consumption +| +-- attachment_queries.go # Attachment CRUD, orphan cleanup +| +-- dm_queries.go # DM channel get-or-create, participants, open/close +| +-- admin_queries.go # Admin stats, audit log, user management, backup/restore ++-- api/ +| +-- router.go # chi router assembly, all route mounting +| +-- middleware.go # AuthMiddleware, RequirePermission, RateLimitMiddleware, +| | # AdminIPRestrict, SecurityHeaders, MaxBodySize(Unless), +| | # clientIP, clientIPWithProxies +| +-- auth_handler.go # POST /register, POST /login, POST /logout, GET /me +| +-- channel_handler.go # GET /channels, GET /channels/{id}/messages, search, pins +| +-- upload_handler.go # POST /uploads, GET /files/{id} +| +-- invite_handler.go # POST /invites, GET /invites, DELETE /invites/{code} +| +-- dm_handler.go # POST /dms, GET /dms, DELETE /dms/{channelId} +| +-- metrics_handler.go # GET /metrics (admin-only runtime stats) +| +-- client_update.go # GET /updates/latest (client auto-update check) +| +-- livekit_proxy.go # /livekit/* reverse proxy (HTTPS->WS to LiveKit) ++-- ws/ +| +-- hub.go # Hub: client tracking, broadcast dispatch, settings cache +| +-- client.go # Client struct: send buffer, channel/voice state, mutexes +| +-- serve.go # ServeWS: upgrade, in-band auth, readPump/writePump, +| | # reconnection replay, ready payload +| +-- handlers.go # Message dispatch switch, chat_send/edit/delete, typing, +| | # presence, channel_focus, reactions +| +-- messages.go # Message builder functions, envelope/payload structs +| +-- errors.go # WebSocket error code constants +| +-- ringbuffer.go # EventRingBuffer for reconnection replay +| +-- voice_join.go # handleVoiceJoin, token generation, rollback logic +| +-- voice_leave.go # handleVoiceLeave, DB cleanup, LiveKit removal +| +-- voice_controls.go # handleVoiceMute/Deafen/Camera/Screenshare +| +-- voice_broadcast.go # Voice quality map, broadcastVoiceStateUpdate +| +-- livekit.go # LiveKitClient: token gen, room management, health check +| +-- livekit_process.go # LiveKitProcess: companion binary lifecycle, restart loop +| +-- livekit_webhook.go # LiveKit webhook handler (participant_joined/left sync) +| +-- origin.go # WebSocket origin validation ++-- permissions/ +| +-- permissions.go # Permission bit constants, role IDs, EffectivePerms ++-- storage/ +| +-- storage.go # File storage: Save, Open, Delete, magic byte validation ++-- admin/ +| +-- admin.go # NewHandler: chi router, embedded static files +| +-- api.go # NewAdminAPI: admin REST routes, auth middleware +| +-- handlers_users.go # Admin user management (list, ban, unban, role change, etc.) +| +-- handlers_channels.go # Admin channel management (create, update, delete, reorder) +| +-- handlers_settings.go # Admin settings (get/patch server settings) +| +-- handlers_backup.go # Backup/restore endpoints +| +-- update_handlers.go # Server update check/apply +| +-- setup_handler.go # First-run setup wizard +| +-- logstream.go # Log ring buffer, MultiHandler for admin log viewer ++-- updater/ +| +-- (updater logic) # GitHub release checking, binary download, hot-swap ++-- migrations/ +| +-- *.sql # Embedded SQL migration files (ordered) +``` + +--- + +## Server Startup Flow + +The `main()` function in `main.go` orchestrates startup in this exact order: + +```text +1.

Detect MIME type from Content-Type header +6. **Magic byte validation**: reads first 8 bytes, rejects: + - PE executables (`MZ` header) -- `.exe`, `.dll` + - ELF binaries (`\x7fELF`) -- Linux + - Mach-O binaries -- macOS + - Shell scripts (`#!` shebang) +7. Write file to `data/uploads/{uuid}` via `storage.Save()` + - Validates size against `upload.max_size_mb` + - Oversized files are deleted after detection +8. Extract image dimensions for `image/*` MIME types +9. Create attachment record in DB (unlinked -- `message_id` is NULL) +10. Return upload response with file URL + +### File Serving (`GET /api/v1/files/{id}`) + +- Public (no auth) -- security via unguessable UUID filenames +- Looks up attachment metadata from DB +- Sets correct MIME type, Content-Disposition, Cache-Control (1 year) +- CORS headers for WebView access +- Serves via `http.ServeContent` (supports range requests) + +### Path Traversal Protection + +`storage.sanitizeFilename()` rejects: +- Empty strings, `.`, `..` +- Filenames with path separators (`/`, `\`) +- Filenames starting with `.` (hidden files) + +`storage.resolvedPath()` verifies the joined path stays within the +storage directory. + +### Orphan Cleanup + +Attachments uploaded but never linked to a message (NULL `message_id`) +are cleaned up by the background maintenance loop after 1 hour. The DB +rows are deleted first, then the files on disk (best-effort). + +--- + +## Admin Panel + +### Architecture + +The admin panel is a browser-based SPA (HTML/CSS/JS) embedded in the +server binary via Go's `embed.FS`. It is served at `/admin` and +restricted to `admin_allowed_cidrs` (default: private networks only). + +### Admin Authentication + +The admin panel uses OwnCord's own auth system. The admin REST API +(`/admin/api/*`) requires both: +1. A valid session token (same Bearer auth as the main API) +2. The user's role must have the `ADMINISTRATOR` permission bit + +### Admin REST API Endpoints (`/admin/api/`) + +| Domain | Key Endpoints | +|--------|---------------| +| Setup | `GET /setup/status`, `POST /setup` (unauthenticated, first-run only) | +| Dashboard | `GET /stats` -- user/message/channel/invite counts, DB size | +| Users | `GET /users`, `PATCH /users/{id}` (role change, ban/unban via `banned` field), `DELETE /users/{id}/sessions` (force logout) | +| Channels | `GET /channels`, `POST /channels`, `PATCH /channels/{id}`, `DELETE /channels/{id}` | +| Settings | `GET /settings`, `PATCH /settings` (whitelisted keys only) | +| Audit Log | `GET /audit-log` | +| Backup | `POST /backup`, `GET /backups`, `DELETE /backups/{name}`, `POST /backups/{name}/restore` (owner-only) | +| Updates | `GET /updates`, `POST /updates/apply` (owner-only) | +| Logs | `GET /logs/stream` (SSE, token via query param) | + +Note: Invite management is handled via the main API (`/api/v1/invites`), +not via admin endpoints. + +### Settings Whitelist + +Only these keys can be written via `PATCH /admin/api/settings`: +`server_name`, `server_icon`, `motd`, `max_upload_bytes`, +`voice_quality`, `require_2fa`, `registration_open`, +`backup_schedule`, `backup_retention`. + +### Server Update Flow + +1. `GET /admin/api/updates/check` queries GitHub Releases for the latest + version (compares via semver) +2. `POST /admin/api/updates/apply` downloads the new binary, renames the + current exe to `.old`, writes the new binary, then restarts the process +3. On next startup, the `.old` file is cleaned up + +### Live Log Streaming + +The admin panel can stream server logs in real-time via SSE (Server-Sent +Events) at `GET /admin/api/logs/stream`. Logs are sourced from the +`admin.RingBuffer` (2000 entries) which receives all log records at +DEBUG level via a `MultiHandler`. + +--- + +## Authentication and Sessions + +### Password Handling + +- Hashed with bcrypt at cost 12 +- Minimum 8 characters, maximum 72 (bcrypt truncation limit) +- `ValidatePasswordStrength()` enforces length rules before hashing +- **Timing-safe**: `CheckPassword()` always performs a bcrypt comparison, + even when the user doesn't exist (compares against a precomputed dummy + hash to prevent timing-based username enumeration) + +### Session Tokens + +- 256-bit random token generated via `crypto/rand` +- Stored as SHA-256 hex digest in the DB (never plaintext) +- 30-day TTL (`sessionTTL = 30 * 24 * time.Hour`) +- `last_used` is updated on each API request (session touch) +- Expired sessions are purged every 15 minutes by the maintenance loop + +### Login Flow + +1. Rate limit check (5 attempts/min/IP) +2. Check lockout status (`login_lock:{ip}`) +3. Constant-time lookup: always attempt bcrypt compare +4. On failure: track via `login_fail:{ip}`, lockout after 10 failures + (15-minute lockout) +5. On success: reset failure counter, check ban status +6. Issue session token, log audit event +7. Return token + user object + +### WebSocket Authentication + +WebSocket connections do NOT use the `AuthMiddleware`. Instead, the first +message must be `{"type":"auth","payload":{"token":"...","last_seq":0}}`. +The token is validated in-band via `authenticateConn()`. + +Duplicate connections are rejected: only one WebSocket connection per +user ID is allowed. This prevents ping-pong reconnect loops. + +--- + +## Permission System + +### Permission Bitfield + +Permissions are a 64-bit integer bitfield defined in `permissions/permissions.go`: + +| Bit | Value | Name | Description | +|-----|-------|------|-------------| +| 0 | `0x0001` | `SEND_MESSAGES` | Send text messages | +| 1 | `0x0002` | `READ_MESSAGES` | View channel content | +| 5 | `0x0020` | `ATTACH_FILES` | Upload file attachments | +| 6 | `0x0040` | `ADD_REACTIONS` | Add emoji reactions | +| 8 | `0x0100` | `USE_SOUNDBOARD` | Use soundboard | +| 9 | `0x0200` | `CONNECT_VOICE` | Join voice channels | +| 10 | `0x0400` | `SPEAK_VOICE` | Speak in voice (publish audio) | +| 11 | `0x0800` | `USE_VIDEO` | Enable camera | +| 12 | `0x1000` | `SHARE_SCREEN` | Share screen | +| 16 | `0x10000` | `MANAGE_MESSAGES` | Edit/delete others' messages | +| 17 | `0x20000` | `MANAGE_CHANNELS` | Create/edit/delete channels | +| 18 | `0x40000` | `KICK_MEMBERS` | Kick users | +| 19 | `0x80000` | `BAN_MEMBERS` | Ban users | +| 20 | `0x100000` | `MUTE_MEMBERS` | Server-mute users | +| 24 | `0x1000000` | `MANAGE_ROLES` | Create/edit roles | +| 25 | `0x2000000` | `MANAGE_SERVER` | Edit server settings | +| 26 | `0x4000000` | `MANAGE_INVITES` | Manage invite codes | +| 27 | `0x8000000` | `VIEW_AUDIT_LOG` | View audit history | +| 30 | `0x40000000` | `ADMINISTRATOR` | Bypasses ALL checks | + +### Default Roles (inserted on first run) + +| ID | Name | Position | Notes | +|----|------|----------|-------| +| 1 | Owner | 100 | All 31 bits set including ADMINISTRATOR | +| 2 | Admin | 80 | Bits 0-29 (everything except ADMINISTRATOR) | +| 3 | Moderator | 60 | Manage messages, kick, ban, mute | +| 4 | Member | 40 | Default for new users | + +### Channel Permission Overrides + +Per-channel overrides use allow/deny semantics following Discord's model: + +``` +effective = (rolePerm & ^deny) | allow +``` + +- `deny` is applied first (strips bits) +- `allow` is applied second (adds bits) +- Allow takes precedence when both target the same bit +- `ADMINISTRATOR` bypasses all override calculations + +### Permission Check Flow + +```text +1.

Test required permission bit(s) +``` + +For REST endpoints, `hasChannelPermBatch()` pre-fetches all overrides +in a single query to eliminate N+1 patterns. + +--- + +## Rate Limiting + +### Implementation + +`auth/ratelimit.go` provides an in-memory sliding-window rate limiter: + +- **Thread-safe**: `sync.Mutex` guards all state +- **Sliding window**: tracks individual timestamps, prunes expired ones +- **Lockout support**: `Lockout(key, duration)` blocks all requests + regardless of window +- **Cleanup**: `Cleanup(maxWindow)` evicts stale entries to prevent + unbounded memory growth + +### Rate Limits by Feature + +| Feature | Key Pattern | Limit | Window | +|---------|-------------|-------|--------| +| Registration | per-IP | 3 | 1 min | +| Login | per-IP | 5 | 1 min | +| Login

certificate generated on first run +- **Four TLS modes**: self_signed, acme (Let's Encrypt), manual, off +- **ACME**: automatic HTTP-01 challenge server on :80 with redirect + +### Authentication Security + +- **Invite-only registration**: no open sign-ups without a valid invite code +- **Atomic invite consumption**: `UseInviteAtomic()` prevents TOCTOU races +- **bcrypt cost 12**: password hashing +- **Timing-safe login**: dummy bcrypt comparison for non-existent users +- **SHA-256 token hashing**: plaintext tokens never stored +- **30-day session TTL**: with periodic revalidation every 10 WS messages +- **Brute-force lockout**: 10 failed logins -> 15-minute IP lockout +- **Ban enforcement**: checked on login, on WS auth, and periodically + during WS connections +- **Duplicate connection rejection**: prevents reconnect loops + +### Input Validation + +- **HTML sanitization**: bluemonday strict policy strips all HTML +- **Message length limit**: 4000 Unicode code points +- **Emoji validation**: max 32 chars, no control characters (U+0000-U+001F, U+007F) +- **File upload validation**: magic byte checks block executables and scripts +- **Body size limits**: 1 MiB default, 100 MiB for uploads +- **YAML config validation**: syntax check before loading + +### Network Security + +- **IP spoofing prevention**: X-Forwarded-For only trusted from + `trusted_proxies` CIDRs +- **Admin IP restriction**: `/admin` routes restricted to private + networks by default +- **Origin validation**: WebSocket origin checking via config +- **CORS**: restrictive by default, file serving allows `*` for WebView + +### Application Security + +- **Generic auth errors**: same error for wrong username and wrong password + (prevents username enumeration) +- **No error detail leakage**: sanitized error messages to clients, + detailed errors logged server-side +- **Audit logging**: all security-relevant actions are logged +- **IDOR prevention**: reaction errors are normalized regardless of + whether the message exists or the user lacks permission +- **LiveKit credential validation**: default dev credentials are rejected +- **Path traversal protection**: filename sanitization + resolved path + validation for file storage +- **YAML injection prevention**: LiveKit credentials validated against + unsafe characters before interpolation + +### HTTP Security Headers + +See the SecurityHeaders middleware section above for the full list. + +--- + +## Error Handling Patterns + +### WebSocket Error Codes + +All WebSocket errors use structured envelopes with string error codes: + +| Code | Meaning | +|------|---------| +| `BAD_REQUEST` | Invalid payload or missing required field | +| `INTERNAL` | Server-side failure | +| `NOT_FOUND` | Resource does not exist | +| `FORBIDDEN` | Permission denied | +| `RATE_LIMITED` | Rate limit exceeded (includes `retry_after`) | +| `ALREADY_JOINED` | Already in the target voice channel | +| `CHANNEL_FULL` | Voice channel at capacity | +| `VOICE_ERROR` | Voice system unavailable | +| `VIDEO_LIMIT` | Maximum video streams reached | +| `BANNED` | User is banned | +| `INVALID_JSON` | Message is not valid JSON | +| `UNKNOWN_TYPE` | Unrecognized message type | +| `SLOW_MODE` | Channel slow mode active | +| `CONFLICT` | Operation conflicts (e.g., duplicate reaction) | + +### REST Error Format + +```json +{ + "error": "ERROR_CODE", + "message": "human-readable description" +} +``` + +### Go Error Wrapping + +All errors are wrapped with `fmt.Errorf("context: %w", err)` to +preserve the error chain for debugging while providing context. + +### Fail-Safe Defaults + +- Unparseable ban expiry -> treated as still banned +- Unparseable session expiry -> treated as expired +- Failed rate limiter CIDR parse -> silently skipped (fallback to RemoteAddr) +- Failed buildReady -> send error message instead of dropping connection +- Failed voice leave DB update -> still broadcast leave to peers +- Failed orphan file deletion -> log warning, continue + +--- + +## Background Maintenance + +A goroutine runs every 15 minutes and performs: + +1. **Delete expired sessions**: removes sessions past their 30-day TTL +2. **Clean orphaned attachments**: files uploaded but never linked to a + message (older than 1 hour) are deleted from DB, then from disk + +### Circuit Breaker + +If the maintenance loop fails 5 consecutive times, it skips one tick +(logs an error) then resets to 4 to allow retry. Successful ticks +reset the counter to 0. + +--- + +## Graceful Shutdown + +On SIGINT or SIGTERM: + +```text +1. Log "shutdown signal received" +2. hub.GracefulStop(): + a. Broadcast server_restart("shutdown", 5) to all clients + b. Stop LiveKit companion process (if managed) + c. Wait 5 seconds for clients to disconnect gracefully + d. Close all remaining client connections (close send channels) + e. Stop the hub dispatch loop +3. srv.Shutdown(30s timeout): + a. Stop accepting new connections + b. Wait for in-flight requests to complete +4. Stop ACME server (if running) +5. Close maintenance goroutine +6.

The mockup HTML/CSS + is the UI. Adding React/Vue/Svelte would require + rewriting the mockup into components with framework + syntax. Vanilla TS lets us copy CSS directly. + +2. **Stores over ViewModel**: Seven focused stores replace + the monolithic ViewModel pattern. Each store handles one + domain. No cross-store dependencies in store files + (the dispatcher is the only cross-store coordinator). + +3. **CSS from mockups**: The mockup CSS IS the production + CSS. No design system rebuild. Just extract and organize. + +4. **Tauri plugins over custom Rust**: Use official plugins + (notification, global-shortcut, store, dialog, fs, + updater, http, opener, process) before writing custom + Rust code. Custom Rust only where plugins can't help: + credentials (Win32 DPAPI), WS proxy (TOFU), PTT + (GetAsyncKeyState), LiveKit proxy (TLS tunnel). + +5. **LiveKit for voice/video**: Voice and video use + LiveKit (SFU) via `livekit-client` JS SDK. The server + runs LiveKit as a companion process alongside + `chatserver.exe`. Client connects via `livekitSession.ts` + using a JWT token from `voice_token` WS message. + +6. **Factory functions over classes**: All components and + services are factory functions returning plain objects. + Exception: `LiveKitSession` (class due to complex async + lifecycle), `RateLimiter` (class for encapsulation), + `Disposable` (class for lifecycle management). + +7. **Immutable state everywhere**: All store state updates + return new objects. Maps and Sets are replaced on every + update, never mutated in place. This matches the + subscription system's shallow equality comparison. diff --git a/docs/brain/06-Specs/DM-SYSTEM.md b/docs/brain/06-Specs/DM-SYSTEM.md new file mode 100644 index 00000000..460b5af6 --- /dev/null +++ b/docs/brain/06-Specs/DM-SYSTEM.md @@ -0,0 +1,481 @@ +# Direct Message (DM) System + +## Complete Architecture Specification + +*Created: 2026-03-28 | Status: IMPLEMENTED | Related: [[CLIENT-ARCHITECTURE]], [[CHATSERVER]], [[SCHEMA]], [[API]], [[PROTOCOL]]* + +--- + +## 1. Executive Summary + +OwnCord supports 1-on-1 direct messages (DMs) as a parallel +communication channel alongside server text channels. DMs have +their own database schema (dm_participants, dm_open_state), REST +API endpoints, WebSocket events, and client-side sidebar mode. +DMs use participant-based authorization (`IsDMParticipant`) instead +of role-based permissions, and every handler that touches a channel +must branch on `ch.Type == "dm"` for authorization. + +--- + +## 2.

Executive Summary + +OwnCord implements reconnection with state recovery at two layers: +the WebSocket chat connection and the LiveKit voice connection. +The WS layer uses a sequence-based ring buffer replay system -- +the client tracks the highest `seq` number received and sends it +on reconnect; the server replays missed events from a 1,000-event +ring buffer. If the client is too far behind, a full `ready` +payload is sent instead. The LiveKit layer has its own auto-reconnect +with stored token reuse. + +--- + +## 2. Architecture Overview + +``` + +---------------------------+ +---------------------------+ + | Client (ws.ts) | | Server (serve.go + hub.go)| + | | | | + | lastSeq = 0 | | seq = atomic.Uint64(0) | + | | | replayBuf = RingBuffer( | + | On each message: | | capacity: 1000) | + | if msg.seq > lastSeq: | | | + | lastSeq = msg.seq | | On each broadcast: | + | | | seq = nextSeq() | + | On reconnect: | | msg = wrapWithSeq(msg, | + | send auth with | | seq) | + | { token, last_seq } | | replayBuf.Push(seq,msg) | + | | | deliver to clients | + +---------------------------+ +---------------------------+ + | | + | auth { token, last_seq: 42 } | + +------------------------------------>| + | | + | 1.

Server-Side: Event Ring Buffer + +### 3.1 Data Structure + +**File:** `Server/ws/ringbuffer.go` + +```go +type eventEntry struct { + seq uint64 + data []byte +} + +type EventRingBuffer struct { + mu sync.RWMutex + entries []eventEntry + size int // Capacity (1,000) + pos int // Next write position (circular) + count int // Total entries stored (up to size) +} +``` + +The ring buffer is a fixed-size circular array with read-write +mutex synchronization. It stores the raw JSON bytes of each +broadcast message along with its sequence number. + +### 3.2 Operations + +| Operation | Complexity | Thread-Safe | Description | +|-----------|-----------|-------------|-------------| +| `Push(seq, data)` | O(1) | Write lock | Overwrite oldest entry at `pos`, advance | +| `EventsSince(afterSeq)` | O(n) | Read lock | Return all entries with `seq > afterSeq` | +| `OldestSeq()` | O(1) | Read lock | Return oldest entry's seq, or 0 if empty | + +### 3.3 EventsSince Logic + +``` +EventsSince(afterSeq): + 1. If buffer is empty: return nil + 2. Find oldest entry index: (pos - count + size) % size + 3. Get oldest seq number + 4. If afterSeq < oldestSeq: return nil // Too far behind + 5. Iterate from oldest to newest: + if entry.seq > afterSeq: add to result + 6. Return result (ordered by seq) +``` + +Returning `nil` (vs empty slice) signals "too old" -- the server +falls back to a full `ready` payload. + +### 3.4 Buffer Capacity + +```go +replayBuf: NewEventRingBuffer(1000) +``` + +1,000 events is sufficient for typical usage (messages, typing +indicators, voice state changes). At ~50 events/minute, this +covers ~20 minutes of missed events. + +--- + +## 4. Server-Side: Sequence Numbers + +### 4.1 Monotonic Counter + +**File:** `Server/ws/hub.go` + +```go +seq uint64 // atomic monotonic counter +``` + +Every broadcast message gets a unique, monotonically increasing +sequence number via `atomic.AddUint64(&h.seq, 1)`. + +### 4.2 Message Stamping + +**File:** `Server/ws/hub.go`, `wrapWithSeq` and `deliverBroadcast` + +```go +func (h *Hub) deliverBroadcast(bm broadcastMsg) { + seq := h.nextSeq() + msg := wrapWithSeq(bm.msg, seq) // Inject "seq" field into JSON + h.replayBuf.Push(seq, msg) // Store for replay + // ... deliver to clients +} +``` + +`wrapWithSeq` injects a `"seq"` field into an existing JSON +message without full re-serialization (string concatenation after +the opening `{`). + +### 4.3 Ephemeral Messages + +Not all messages are stored in the ring buffer. Messages sent via +`broadcastExclude` (e.g., typing indicators) are NOT stored -- they +are ephemeral and should not survive reconnection replay. + +| Stored in Ring Buffer (via `BroadcastToChannel`/`BroadcastToAll`) | NOT Stored (via `broadcastExclude`/`SendToUser`) | +|------------------------------------------------------------------|--------------------------------------------------| +| `chat_message` (non-DM only) | `typing` (ephemeral, `broadcastExclude`) | +| `chat_edited` (non-DM only) | `dm_channel_open` (direct via `SendToUser`) | +| `chat_deleted` (non-DM only) | `dm_channel_close` (direct via `SendToUser`) | +| `reaction_update` (non-DM only) | DM `chat_message`/`chat_edited`/`chat_deleted`/`reaction_update` | +| `presence` | | +| `voice_state` | | +| `voice_leave` | | +| `member_join` | | +| `member_update` | | +| `member_ban` | | +| `channel_create` | | +| `channel_update` | | +| `channel_delete` | | +| `server_restart` | | + +**Note:** DM events (chat messages, reactions, open/close) are sent +via `SendToUser` and bypass the broadcast channel entirely.

This ensures +the stored token is not close to expiry. The token refresh timer +(3.5 hours) is also restarted. + +--- + +## 8. Heartbeat Monitoring + +### 8.1 Client-Side + +**File:** `Client/tauri-client/src/lib/ws.ts` + +```typescript +const HEARTBEAT_INTERVAL_MS = 30_000; + +function startHeartbeat(): void { + heartbeatTimer = setInterval(() => { + send({ type: "ping", payload: {} }); + }, HEARTBEAT_INTERVAL_MS); +} +``` + +### 8.2 Server-Side + +The server sweeps for stale connections every 30 seconds and kicks +clients with no activity for 90 seconds.

Edge Cases + +### 10.1 Duplicate Connection Prevention + +The server rejects duplicate logins: + +```go +if hub.IsUserConnected(user.ID) { + conn.Write("already connected from another client") + conn.Close(StatusPolicyViolation, "already connected") + return +} +``` + +This prevents ping-pong reconnect loops where a new connection +opens before the old one is fully cleaned up. + +### 10.2 Ring Buffer Overflow + +If the client is disconnected for longer than the ring buffer +can cover (~20 minutes at typical activity), `EventsSince` returns +nil. The server falls through to a full `ready` payload, which +is equivalent to a fresh login. + +### 10.3 Voice Reconnect During WS Reconnect + +The WS reconnect and LiveKit reconnect are independent: +- WS reconnect restores chat state (messages, presence, etc.) +- LiveKit reconnect restores voice state (room connection, tracks) + +If the WS reconnect succeeds but LiveKit fails, the user remains +in chat but loses voice. The error callback notifies: "Voice +connection lost -- failed to reconnect". + +### 10.4 Token Expiry During Disconnect + +LiveKit tokens have a 4-hour TTL. If the disconnect period exceeds +this, the stored token is expired and auto-reconnect fails. The +client must rejoin voice manually (which requests a new token). + +--- + +## 11.

A client in channel A receives replayed events + from channel B too (which are filtered client-side). +3. **Fixed capacity:** The 1,000-event buffer is not configurable + without code changes. +4. **No offline message queue:** Messages sent while the client is + disconnected are only available if they're in the ring buffer. + There is no persistent offline queue. +5. **LiveKit reconnect uses stored token:** If the token is close + to expiry, reconnect may fail.

[Query Patterns](#query-patterns) + +--- + +## Database Configuration + +The database is opened and configured in `db.Open()`. Every connection has +the following PRAGMAs applied at startup before any queries execute: + +| PRAGMA | Value | Purpose | +|--------|-------|---------| +| `journal_mode` | `WAL` | Write-Ahead Logging. Allows concurrent readers while one writer operates. Dramatically improves read throughput for a single-writer system. | +| `foreign_keys` | `ON` | Enforces all `REFERENCES` constraints. Without this, SQLite silently ignores foreign keys. | +| `busy_timeout` | `5000` | Waits up to 5 seconds for the write lock instead of returning `SQLITE_BUSY` immediately. Prevents transient failures under load. | +| `synchronous` | `NORMAL` | Safe with WAL mode. Reduces fsync calls compared to `FULL`. Data is durable against application crashes; only an OS crash during a checkpoint could theoretically lose committed data. | +| `temp_store` | `MEMORY` | Temporary tables and indices are stored in RAM instead of on disk. Speeds up sorting, grouping, and complex queries. | +| `mmap_size` | `268435456` | 256 MB memory-mapped I/O. The OS maps the database file directly into the process address space, avoiding `read()` system calls for hot pages. | +| `cache_size` | `-64000` | Negative value = kilobytes. Sets the page cache to 64 MB (approximately 15,000 pages at 4 KB page size). Keeps frequently accessed pages in memory. | + +### Connection Pooling + +```go +sqlDB.SetMaxOpenConns(1) +``` + +SQLite only allows one writer at a time. The pool is pinned to a **single +connection** so concurrent goroutines queue on the Go side (via `sync.Mutex` +inside `database/sql`) rather than getting `SQLITE_BUSY` errors. For +`:memory:` databases this also guarantees all callers share the same state. + +Reads and writes are serialized through this single connection. WAL mode +still benefits performance because the single connection can read its own +uncommitted data, and the OS-level mmap avoids redundant I/O. + +### Shutdown + +On `db.Close()`, `PRAGMA optimize` is executed first. This lets SQLite +analyze and update query planner statistics based on actual usage during the +session, improving plan quality on the next startup. + +--- + +## Migration System + +Source: `db/migrate.go` + +### Tracking Table + +```sql +CREATE TABLE IF NOT EXISTS schema_versions ( + version TEXT PRIMARY KEY, -- migration filename (e.g. "001_initial_schema.sql") + applied_at TEXT NOT NULL DEFAULT (datetime('now')) -- UTC timestamp of application +); +``` + +### How It Works + +1. **Collect** all `.sql` files from the embedded `migrations/` FS, + sorted lexicographically by filename. +2. **Seed existing databases**: If `schema_versions` does not exist but + `users` does, this is a pre-tracking database. All migration filenames + are inserted into `schema_versions` without executing the SQL, preventing + destructive re-application. +3. **Apply new migrations**: For each `.sql` file not yet in `schema_versions`: + - Begin a transaction. + - Execute the SQL. + - Insert the filename into `schema_versions` inside the same transaction. + - Commit. If the server crashes between commit and the next migration, + the already-applied migration is recorded and will not re-run. + +### Migration History + +| File | Description | +|------|-------------| +| `001_initial_schema.sql` | All core tables: roles, users, sessions, channels, channel_overrides, messages, messages_fts, attachments, reactions, invites, read_states, audit_log, login_attempts, settings, emoji, sounds. Default roles and settings inserted. | +| `002_voice_states.sql` | Adds `voice_states` table with user_id (PK), channel_id, muted, deafened, speaking, joined_at. Adds `idx_voice_states_channel` index. | +| `003_audit_log.sql` | Recreates `audit_log` with Phase-6 column names: `actor_id` (was `user_id`), `detail` (was `details`), `created_at` (was `timestamp`). Adds `idx_audit_log_actor` index. | +| `003_voice_optimization.sql` | Adds `camera` and `screenshare` columns to `voice_states`. Adds `voice_max_users`, `voice_quality`, `mixing_threshold`, `voice_max_video` to `channels`. | +| `004_fix_member_permissions.sql` | Fixes Member role: adds READ_MESSAGES, ATTACH_FILES, ADD_REACTIONS bits. New value: `0x663` (1635). | +| `005_channel_overrides_index.sql` | Adds composite index `idx_channel_overrides_channel_role` on `(channel_id, role_id)`. | +| `006_member_video_permissions.sql` | Adds USE_VIDEO and SHARE_SCREEN to Member role. New value: `0x1E63` (7779). | +| `007_attachment_dimensions.sql` | Adds `width` and `height` nullable INTEGER columns to `attachments`. | +| `008_dm_tables.sql` | Adds `dm_participants` table (composite PK: channel_id, user_id) and `dm_open_state` table. Adds `idx_dm_participants_user`. | + +Note: `003_audit_log.sql` and `003_voice_optimization.sql` both have the +`003` prefix. Lexicographic ordering places `003_audit_log.sql` before +`003_voice_optimization.sql`, so they apply in that order. + +--- + +## Sentinel Errors + +Source: `db/errors.go` + +The `db` package defines four sentinel errors. All query functions wrap +errors using `fmt.Errorf("...: %w", err)` so callers can check with +`errors.Is()`: + +| Error | Value | Usage | +|-------|-------|-------| +| `ErrNotFound` | `"not found"` | Resource does not exist (e.g., message not found on edit/delete, setting key missing). | +| `ErrForbidden` | `"forbidden"` | Caller lacks permission (e.g., editing another user's message). | +| `ErrConflict` | `"conflict"` | Uniqueness constraint violation (e.g., duplicate username on registration). | +| `ErrBanned` | `"banned"` | User is banned from the server. | + +Query functions return `nil, nil` (not `ErrNotFound`) when a lookup returns +no rows for `GetUserByID`, `GetChannel`, `GetInvite`, `GetVoiceState`, etc. +The `ErrNotFound` sentinel is used for operations that fail when the resource +is absent (e.g., `EditMessage`, `DeleteMessage`, `SetMessagePinned`, +`UseInviteAtomic`). + +--- + +## Tables + +### roles + +Defines permission tiers.

Without this, every API call would require a full table scan. | +| `idx_sessions_user` | sessions | `(user_id)` | Fast deletion of all sessions for a user (force logout, ban). Also used by `GetUserSessions`. | +| `idx_messages_channel` | messages | `(channel_id, id DESC)` | Primary query pattern: "get latest N messages in channel X". The compound index covers both the WHERE clause and ORDER BY in a single index scan, avoiding a filesort. DESC ensures newest messages are found first. | +| `idx_messages_user` | messages | `(user_id)` | Supports queries filtering by author (e.g., "messages by user X"). Currently used by potential future moderation queries. | +| `idx_invites_code` | invites | `(code)` | Fast invite validation during registration. The `code` column is already UNIQUE, so this index is redundant (SQLite auto-creates an index for UNIQUE constraints). Kept for documentation clarity. | +| `idx_audit_timestamp` | audit_log | `(created_at DESC)` | Pagination of audit log entries (newest first). The `GetAuditLog` query orders by `id DESC`, but this index on `created_at DESC` still helps when filtering by time range. | +| `idx_audit_log_actor` | audit_log | `(actor_id)` | Filter audit log entries by actor (e.g., "what did user X do?"). Added in migration 003. | +| `idx_login_ip` | login_attempts | `(ip_address, timestamp)` | Rate limiting: "how many failed attempts from IP X in the last 15 minutes?" The compound index supports both the WHERE filter on IP and the time-range condition. | +| `idx_voice_states_channel` | voice_states | `(channel_id)` | Fast lookup of all users in a given voice channel. Used by `GetChannelVoiceStates`, `CountChannelVoiceUsers`, and `CountActiveCameras`. | +| `idx_channel_overrides_channel_role` | channel_overrides | `(channel_id, role_id)` | Covers the `GetChannelPermissions` query exactly (`WHERE channel_id = ? AND role_id = ?`). Added in migration 005 to prevent N+1 degradation when listing channels with permission checks. | +| `idx_dm_participants_user` | dm_participants | `(user_id)` | Supports the DM channel lookup query in `GetOrCreateDMChannel`, which JOINs `dm_participants` on `user_id`.

FROM attachments WHERE id = ?` | Returns `nil, nil` if not found. | +| `LinkAttachmentsToMessage` | `UPDATE attachments SET message_id = ? WHERE id IN (?,?,...) AND message_id IS NULL` | Dynamic IN-clause. `AND message_id IS NULL` prevents double-linking in concurrent races. Returns rows affected. | +| `GetAttachmentsByMessageIDs` | `SELECT id, message_id, filename, size, mime_type, width, height FROM attachments WHERE message_id IN (?,?,...)` | Batch fetch for message enrichment.

Delegates to `BackupToSafe` with `data/backups` as safe root. | +| `BackupToSafe` | Same SQL, with path validation | **Security**: Path is validated against a safe root directory (must be a subdirectory). Characters `'`, `"`, `;`, `--`, `\x00` are rejected as defense-in-depth. `VACUUM INTO` does not support bind parameters, so structural validation is critical. | + +--- + +## Query Patterns + +### Prepared Statements + +The codebase does **not** use explicitly prepared statements +(`sql.Prepare`). Instead, all queries pass SQL strings directly to +`db.Exec()`, `db.Query()`, and `db.QueryRow()`. The `database/sql` +package internally caches prepared statements when using parameterized +queries, so the performance difference is negligible for a single-connection +pool. + +### Transaction Handling + +Transactions are used in two places: + +1. **Migrations** (`migrate.go`): Each migration executes within a + transaction. The migration SQL and its tracking record are committed + atomically. + +2. **DM channel creation** (`dm_queries.go`): `GetOrCreateDMChannel` uses + `BeginTx` with `sql.LevelSerializable` isolation to prevent TOCTOU + races. The transaction covers: lookup existing DM -> create channel -> + insert participants -> insert open state -> commit. + +All other operations are single-statement and rely on SQLite's implicit +auto-commit transactions. + +### Batch Query Pattern + +Several functions use dynamic `IN (?, ?, ...)` clauses for batch +operations: + +- `getReactionsBatch`: Aggregates reactions for multiple message IDs. +- `GetAttachmentsByMessageIDs`: Fetches attachments for multiple messages. +- `LinkAttachmentsToMessage`: Links multiple attachment IDs to a message. + +These build placeholder strings dynamically using `strings.Builder` and +pass args as `[]any` slices. This avoids N+1 query problems when enriching +message lists. + +### Scan Helpers + +The codebase uses dedicated scan functions to handle SQLite's lack of +native boolean type: + +- `scanUser`: Scans `banned` as `int`, converts to `bool`. +- `scanMessage`: Scans `deleted` and `pinned` as `int`, converts to `bool`. +- `scanVoiceState` / `scanVoiceStateRow`: Scans all flag columns as `int`. +- `scanChannel`: Scans `archived` as `int`. + +Pattern: `field = intValue != 0` + +### NULL Handling + +- `nullableString(s string) any`: Returns `nil` when `s` is empty, so + empty strings are stored as SQL NULL in optional TEXT columns (`category`, + `topic`). Read back with `COALESCE(column, '')`. +- `boolToInt(b bool) int`: Converts Go `bool` to `0`/`1` for SQLite storage. +- Optional fields use Go pointer types (`*string`, `*int`, `*int64`) to + represent SQL NULLs. `sql.NullInt64` is used in `GetUserDMChannels`. + +### Datetime Conventions + +- All timestamps stored as ISO 8601 UTC strings: + `"2006-01-02T15:04:05Z"` (Go reference format) or + `datetime('now')` (SQLite function). +- Comparison uses `strftime('%s', column)` to convert to Unix timestamps + for reliable ordering across format variations. +- `COALESCE` handles NULL timestamps in joins (e.g., DM channels with no + messages yet). diff --git a/docs/brain/06-Specs/SCREENSHARE-AUDIO.md b/docs/brain/06-Specs/SCREENSHARE-AUDIO.md new file mode 100644 index 00000000..17a0c7bb --- /dev/null +++ b/docs/brain/06-Specs/SCREENSHARE-AUDIO.md @@ -0,0 +1,586 @@ +# Screenshare Audio + Per-Tile Volume Controls + +## Complete Architecture Specification + +*Updated: 2026-03-28 | Status: IMPLEMENTED | Related: [[VIDEO-FOCUS-MODE]], [[CLIENT-ARCHITECTURE]], [[DEC-009-livekit-migration]]* + +--- + +## 1. Executive Summary + +OwnCord's screen sharing system is built on the LiveKit client SDK. +The sender captures both a video and an audio track via the browser's +`getDisplayMedia` API (through LiveKit's `createLocalScreenTracks` +helper). The receiver subscribes to these tracks and renders them +in a VideoGrid tile with per-tile mute/volume controls. Audio for +screen shares is managed separately from microphone audio to allow +independent volume control. + +--- + +## 2.

Prerequisites (Manual Install) + +These require GUI installers, admin privileges, or system-level changes. +Claude Code cannot install these for you. + +### Required + +| Tool | Version | Download | Verify | +|------|---------|----------|--------| +| Git | any | <https://git-scm.com/download/win> | `git --version` | +| Go | 1.25+ | <https://go.dev/dl/> (amd64 .msi) | `go version` | +| Node.js | 20 LTS+ | <https://nodejs.org> | `node --version` | +| Rust | stable | <https://rustup.rs> (`rustup-init.exe`) | `rustc --version` | +| VS Build Tools 2022 | latest | [Download](https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2022) | N/A | + +#### Git + +Default install options are fine. Ensure Git Bash is available +(used by Claude Code and npm scripts). + +#### Go 1.25+ + +Download the Windows amd64 `.msi` installer from <https://go.dev/dl/>. +The `go.mod` specifies `go 1.25.0` as the minimum version. After install, +the `GOPATH` defaults to `%USERPROFILE%\go` and `%GOPATH%\bin` should be +on your PATH for tool binaries (`air`, `golangci-lint`). + +#### Node.js 20 LTS + +Required for the Tauri frontend build toolchain (Vite, TypeScript, +Vitest, Playwright). The `package.json` uses `"type": "module"` (ESM). +npm ships with Node. + +#### Rust (stable toolchain) + +Install via `rustup-init.exe` from <https://rustup.rs>. The stable +toolchain is sufficient. Cargo (Rust's package manager) is included. +Verify with `rustc --version` and `cargo --version`. + +#### Visual Studio Build Tools 2022 + +Required for Rust compilation on Windows. During install, select: +- "Desktop development with C++" +- Requires approximately 3-5 GB of disk space. + +This provides `cl.exe`, `link.exe`, and the Windows SDK needed by the +`windows` crate and Tauri's native compilation. + +### Optional but Recommended + +| Tool | Purpose | Install | +|------|---------|---------| +| Windows Terminal | Better shell experience | <https://aka.ms/terminal> | +| VS Code | IDE with extension ecosystem | <https://code.visualstudio.com> | +| NSIS | Installer builder for Tauri | `winget install NSIS.NSIS` | + +--- + +## 2.

LiveKit Voice Server Setup + +LiveKit is a WebRTC SFU (Selective Forwarding Unit) that handles +voice and video relay.

Start `livekit-server.exe` as a child process +2. Configure it with matching API key/secret +3. Stop it on server shutdown + +### Option B: External LiveKit Server + +Run LiveKit separately (Docker, cloud, etc.): + +```bash +# Docker example +docker run --rm -p 7880:7880 -p 7881:7881 \ + -e LIVEKIT_KEYS="my-api-key: my-secret-at-least-32-characters-long" \ + livekit/livekit-server +``` + +Configure OwnCord to connect to it: + +```yaml +voice: + livekit_api_key: "my-api-key" + livekit_api_secret: "my-secret-at-least-32-characters-long" + livekit_url: "ws://localhost:7880" + # livekit_binary: "" (empty = don't auto-start) +``` + +### LiveKit Signal Path + +The client connects to LiveKit through two possible paths: + +``` +Path 1: OwnCord HTTPS Reverse Proxy (default) + Client --wss://{server}:8443/livekit/*--> OwnCord + OwnCord --ws://localhost:7880/*--> LiveKit + +Path 2: LiveKit TLS Proxy (self-signed cert workaround) + Client --ws://127.0.0.1:{port}/livekit/*--> Rust Proxy + Rust Proxy --TLS--> Remote Server --ws://--> LiveKit +``` + +Path 2 is used when connecting to a remote server with a self-signed +certificate, because the LiveKit JS SDK opens its own WebSocket and +WebView2 rejects self-signed certs. The Rust-side `livekit_proxy.rs` +module creates a local TCP listener that tunnels to the remote server +over TLS. + +--- + +## 9.

Troubleshooting + +### Server Issues + +**"address already in use" on startup**: +The server retries port binding up to 20 times with 500ms delays. +This handles the common case where a previous process has not +released the port yet. If it persists, kill the old process: +`taskkill /F /IM chatserver.exe` + +**"default LiveKit dev credentials" warning**: +Set unique `voice.livekit_api_key` and `voice.livekit_api_secret` +in `config.yaml`. Random credentials are generated per-startup as a +fallback but tokens break on server restart. + +**Database locked errors**: +SQLite is configured with `MaxOpenConns(1)` and `busy_timeout(5000ms)`. +Under extreme write load, operations may queue. This is expected. + +**Migration errors**: +Migrations are idempotent (`CREATE TABLE IF NOT EXISTS`, `INSERT OR IGNORE`). +If a migration fails, fix the issue and restart. The `schema_versions` +table tracks which migrations have been applied. + +### Client Issues + +**"wasm-unsafe-eval" CSP error**: +The CSP allows `wasm-unsafe-eval` for the RNNoise WASM noise suppression +module. If you see CSP violations, check that `tauri.conf.json`'s CSP +includes `script-src 'self' 'wasm-unsafe-eval'`. + +**WebSocket connection fails**: +The client's WS proxy (`ws_proxy.rs`) handles self-signed certs via TOFU. +On first connect, the cert fingerprint is stored. If the server regenerates +its cert, the client will reject the connection with a cert-mismatch error. +The user must acknowledge the new cert via `accept_cert_fingerprint`. + +**LiveKit "could not establish signal connection"**: +This means WebView2's native fetch is rejecting the self-signed cert. +The `livekit_proxy.rs` module solves this by proxying through localhost. +Ensure the proxy is starting correctly (check Rust logs). + +**Tauri build fails on `windows` crate**: +Ensure "Desktop development with C++" is installed in VS Build Tools. +The `windows` crate uses Win32 API bindings that require the Windows SDK. + +**"npm run tauri dev" is slow to start**: +First Rust compilation takes 2-5 minutes (downloading + compiling crates). +Subsequent builds are incremental (10-30 seconds). Use `cargo check` for +faster feedback during Rust-only changes. + +--- + +## Summary Table + +| Tool | You Install | Claude Code Installs | +|------|:-----------:|:--------------------:| +| Git | X | | +| Go 1.25+ | X | | +| Node.js 20 LTS | X | | +| Rust (stable) | X | | +| VS Build Tools 2022 | X | | +| Windows Terminal | (optional) | | +| VS Code | (optional) | | +| Go libraries | | X (go mod download) | +| NPM packages | | X (npm install) | +| Rust crates | | X (cargo build) | +| NSIS | | X (winget) | +| Playwright browsers | | X (npx playwright install) | +| Linters (air, golangci-lint) | | X (go install) | +| LiveKit server binary | X or Docker | | diff --git a/docs/brain/06-Specs/TECH-STACK-RESEARCH.md b/docs/brain/06-Specs/TECH-STACK-RESEARCH.md new file mode 100644 index 00000000..96be5cef --- /dev/null +++ b/docs/brain/06-Specs/TECH-STACK-RESEARCH.md @@ -0,0 +1,370 @@ +# Tech Stack Research: Self-Hosted LAN Discord + TeamSpeak Clone + +## Complete Technology Assessment + +*Updated: 2026-03-28 | Sources: 30+ | Confidence: High* +*Related: [[DEC-001-tauri-migration]], [[DEC-002-sqlite-pure-go]], [[DEC-009-livekit-migration]], [[DEC-010-livekit-tls-proxy]]* + +--- + +## Executive Summary + +**OwnCord's stack (Go + Tauri v2/Rust + TypeScript + LiveKit) is well-chosen for its requirements.** The LiveKit migration (DEC-009) eliminated the #1 source of bugs -- the hand-rolled Pion SFU -- and replaced it with a battle-tested open-source SFU. Go with the LiveKit server SDK is the strongest WebRTC language. Tauri v2 on Windows is the lightest desktop client framework with full WebRTC support via WebView2. The three-language cost is real but manageable. The main remaining pain points are SQLite concurrency, cross-language type synchronization, and testing coverage gaps. + +--- + +## 1.

Why Each Technology Was Chosen + +### 2.1 Go (Server) + +**Decision:** Implicit from project inception, validated by [[DEC-009-livekit-migration]]. + +| Factor | Score | Notes | +|--------|-------|-------| +| WebRTC ecosystem | Excellent | Pion (pure Go) is the foundation of LiveKit | +| Compile speed | Fast | ~0.3s for examples, ~1min full test suite | +| Single binary deployment | Yes | `chatserver.exe` -- no runtime dependencies | +| Concurrency | Excellent | Goroutines for WS hub, broadcasts, heartbeat | +| Cross-compilation | Good | `GOOS=windows GOARCH=amd64 go build` | +| CGo-free SQLite | Yes | modernc.org/sqlite (pure Go, [[DEC-002-sqlite-pure-go]]) | +| Memory footprint | Low | ~20-40MB at idle for the chat server | + +**Alternatives considered:** Rust (too slow to compile for rapid iteration), Node.js (mediasoup exists but C++ worker is a black box), C++ (Janus -- powerful but hard to extend). + +### 2.2 SQLite (Database) + +**Decision:** [[DEC-002-sqlite-pure-go]] -- pure Go SQLite via modernc.org/sqlite. + +| Factor | Score | Notes | +|--------|-------|-------| +| Zero-config deployment | Yes | Single file, no external process | +| Self-hosted fit | Excellent | Perfect for single-server, 1-50 users | +| FTS5 full-text search | Yes | Used for message search | +| Transaction support | Yes | ACID, WAL mode for concurrent reads | +| Windows file locking | Stricter | Required `busy_timeout=5000`, `SetMaxOpenConns(1)` | + +**Why not PostgreSQL?** OwnCord targets self-hosted home servers. PostgreSQL adds deployment complexity. SQLite with WAL mode handles the expected 1-50 concurrent users. If SQLITE_BUSY errors become problematic under heavy load, PostgreSQL is the escape hatch. + +**Why pure Go (modernc.org)?** Eliminates CGo dependency, enabling true single-binary deployment and simpler cross-compilation. Performance is within 5-15% of the CGo mattn/go-sqlite3 driver for OwnCord's workload. + +### 2.3 Tauri v2 (Desktop Client) + +**Decision:** [[DEC-001-tauri-migration]]. + +| Factor | Score | Notes | +|--------|-------|-------| +| Memory (idle) | ~30-40 MB | vs Electron's 200-300 MB | +| Bundle size | ~600KB-10 MB | vs Electron's 80-150 MB | +| Startup time | <0.5s | vs Electron's 1-2s | +| WebRTC on Windows | Full support | WebView2 = Chromium under the hood | +| System API access | Via Rust | GetAsyncKeyState, Credential Manager, etc. | +| Auto-updater | Built-in (v2) | Ed25519-signed releases | +| Security model | ACL-based | Fine-grained capability permissions | + +**Why not Electron?** 5-8x more RAM, huge bundle size. OwnCord targets gamers where every MB of RAM matters. + +**Known risk:** Linux WebRTC is broken in WebKitGTK ([tauri#13143](https://github.com/tauri-apps/tauri/issues/13143)). OwnCord is Windows-primary, so this is acceptable. + +### 2.4 LiveKit (Voice/Video SFU) + +**Decision:** [[DEC-009-livekit-migration]] -- replaced the hand-rolled Pion SFU. + +| Factor | Score | Notes | +|--------|-------|-------| +| SDP negotiation | Handled by LiveKit | Eliminated ~2,000 lines of bug-prone code | +| Speaker detection | Built-in | `ActiveSpeakersChanged` event | +| Bandwidth estimation | Built-in | Adaptive bitrate, simulcast | +| TURN relay | Built-in | For NAT traversal | +| Reconnection | Built-in | With LiveKit's own retry logic | +| MIT license | Yes | Fully self-hostable | +| Client SDK | livekit-client (TS) | Rich API for tracks, rooms, events | +| Server SDK | server-sdk-go/v2 | Token generation, room management | + +**What was replaced:** +- Server: `sfu.go`, `voice_room.go`, `speaker_detector.go`, `rtp_audio_level.go`, `speaker_broadcast.go`, `voice_handler.go` (~2,000 lines) +- Client: `webrtc.ts`, `vad.ts`, `voiceSession.ts`, `audio.ts`, `video.ts`, `Soundboard.ts` (~1,900 lines) +- Added: `livekit.go`, `livekit_process.go`, `livekitSession.ts` (~1,000 lines) +- **Net savings:** ~1,800 fewer lines of the most bug-prone code + +**What was kept:** RNNoise WASM for enhanced noise suppression (optional, via LiveKit's TrackProcessor API). The `@livekit/krisp-noise-filter` was considered but `@jitsi/rnnoise-wasm` was already integrated and working. + +### 2.5 TypeScript (Frontend) + +Standard choice for web UIs with good tooling. The `lib/` layer +uses vanilla TypeScript with no framework (no React, Svelte, etc.) +to keep the bundle small and avoid framework lock-in. DOM +manipulation uses custom `createElement`/`appendChildren` helpers. + +### 2.6 Rust (Tauri Backend) + +Required by Tauri v2. Used for: +- **WS proxy** (`ws_proxy.rs`): Tunnels WebSocket through Rust with TOFU cert pinning for self-signed TLS +- **LiveKit TLS proxy** (`livekit_proxy.rs`): Local TCP-to-TLS tunnel for LiveKit signaling ([[DEC-010-livekit-tls-proxy]]) +- **Push-to-talk** (`ptt.rs`): `GetAsyncKeyState` polling for global hotkeys +- **Credential storage**: Windows Credential Manager for session tokens + +--- + +## 3.

Remove all inline `--*` CSS custom properties from body.style + 3. Check if name is in BUILT_IN_THEMES array -> No + 4. Load from localStorage: owncord:theme:custom:my-custom + 5. Parse JSON, validate shape (name: string, colors: object required; + author + version not validated at load time) + 6. Add `theme-custom` class to body + 7.

Set body.style.setProperty(prop, value) + 8. Save to localStorage: owncord:theme:active = "my-custom" +``` + +### 5.3 Security: CSS Injection Prevention + +Custom theme values are validated against an allowlist regex: + +```typescript +// Property name: must be --{valid-css-ident} +if (!prop.startsWith("--") || !/^[a-zA-Z_][\w-]*$/.test(prop.slice(2))) continue; +// Value: only permit safe CSS color/sizing characters +if (!/^[\w\s#().,%+\-/]+$/.test(value)) continue; +``` + +This blocks: +- `url()` (no external resource loading) +- `expression()` (no IE script injection) +- Semicolons, braces, `!important` (no CSS injection) +- Any non-alphanumeric/safe characters + +--- + +## 6. Accent Color Override + +### 6.1 How It Works + +The accent color picker in AppearanceTab lets users override the +`--accent` CSS variable on top of any theme. This is applied as +an inline style on both `document.documentElement` and +`document.body`: + +```typescript +document.documentElement.style.setProperty("--accent", "#ff6b6b"); +document.body.style.setProperty("--accent", "#ff6b6b"); +``` + +Because inline styles have higher specificity than CSS class rules, +the accent override wins over the theme's `--accent` value. + +### 6.2 Persistence + +Saved to localStorage as `owncord:settings:accentColor` (JSON string). +Note: Previously used `owncord:pref:accentColor` — this was corrected to +match the actual storage key used by AppearanceTab. + +### 6.3 Restore Order + +In `restoreTheme()`: +1. Apply the saved theme (by name) +2. Then apply the accent color override + +The accent must be applied AFTER the theme so it wins via inline +style specificity. + +### 6.4 Validation on Restore + +```typescript +const accent = JSON.parse(raw); +if (typeof accent === "string" && /^#[\da-fA-F]{3,8}$/.test(accent)) { + // Apply -- only valid hex colors accepted +} +``` + +--- + +## 7. Theme Lifecycle + +### 7.1 App Startup + +``` +main.ts: + restoreTheme() + | + +--> applyThemeByName(getActiveThemeName()) + | // Applies CSS class or custom properties + | + +--> Restore accent color from owncord:pref:accentColor + // Inline style override on html + body +``` + +### 7.2 User Changes Theme + +``` +AppearanceTab -> theme selector dropdown: + applyThemeByName(selectedName) + // Removes old theme class, applies new one + // Persists to owncord:theme:active +``` + +### 7.3 User Changes Accent Color + +``` +AppearanceTab -> accent color picker: + 1. document.documentElement.style.setProperty("--accent", color) + 2. document.body.style.setProperty("--accent", color) + 3. savePref("accentColor", color) +``` + +### 7.4 Custom Theme Import + +``` +AppearanceTab -> Import button: + 1.

No server-side theme storage or sharing. +3. **Accent-only override:** Only `--accent` can be overridden via + the color picker. Other properties require a custom theme JSON. +4. **No gradient override:** The accent color picker only sets a + solid `--accent` color. To change the gradient, a custom theme + must override `--accent-gradient`. +5. **localStorage-only:** Theme state is not synced across devices + or backed up. Clearing browser storage loses custom themes. +6. **No dark/light mode auto-detection:** No support for + `prefers-color-scheme` media query.

Protocol: Heartbeat Improvements + +### Current State +Client sends `ping` every 30s. Server responds with `pong`. No server-initiated keepalive. If the server detects a dead connection, it only notices when a `conn.Read` or `conn.Write` fails. + +### What Production Platforms Do +Discord's gateway sends server-initiated heartbeats at a specified interval (sent in the `HELLO` event). If the client misses sending a heartbeat response, the server closes the connection. This is bidirectional: both sides monitor liveness. + +### Recommendation +- Server should also track last-received-message time per client +- If no message received from a client in 60s (2x heartbeat interval), close the connection as stale +- This prevents "ghost connections" where the client process crashed but TCP hasn't timed out yet +- The `readPump` can check `time.Since(c.lastActivity)` periodically + +--- + +## 9.

Client: Store Subscription Efficiency + +### Current State +`store.ts` uses `queueMicrotask` for batched notifications — excellent. But `subscribe()` fires on EVERY state change, and components must use `subscribeSelector` manually to avoid unnecessary re-renders. + +### What Production Platforms Do +Element uses a Flux dispatcher with fine-grained event types. Zustand (used by many production apps) defaults to selector-based subscriptions with shallow equality. + +### Recommendation +- Make `subscribeSelector` the primary API. Rename it to just `subscribe` and make the old `subscribe` into `subscribeAll` (rare use case) +- Add a built-in `shallowEqual` comparator for array/object selectors +- Consider adding a `batch()` utility for coordinated multi-store updates (e.g., when the `ready` payload updates channels, members, voice states, and roles simultaneously) + +This reduces wasted re-renders and is the pattern used by Zustand, Jotai, and Redux Toolkit. + +--- + +## 11. Client: WebSocket Reconnection with State Recovery + +### Current State +`ws.ts` has exponential backoff reconnection — good. But on reconnect, the client re-authenticates and gets a fresh `ready` payload. Any messages received between disconnect and reconnect are lost. + +### What Production Platforms Do +- Discord replays missed events using sequence numbers (see #7) +- Slack has a "catch up" mechanism that fetches missed events on reconnect +- Matrix resumes from the last sync token + +### Recommendation (client side of #7) +1. Track last received `seq` number +2. On reconnect, send `last_seq` in the auth message +3. If the server can replay, process the replayed events normally +4. If too far behind (server returns `"resync_required"`), do a full state refresh (current behavior) +5. During reconnect, queue outbound messages locally and flush after reconnection + +--- + +## 12. Go Server: Request-Scoped Structured Logging + +### Current State +Log lines include `user_id` and sometimes `channel_id`, but each log call adds these manually. There's no correlation ID across a single message's lifecycle. + +### What Production Platforms Do +Matrix's Dendrite uses request-scoped loggers with `slog.With()` to carry context through an entire handler chain. + +### Recommendation +In `handleMessage`, create a request-scoped logger: +```go +reqLog := slog.With( + "user_id", c.userID, + "msg_type", env.Type, + "req_id", env.ID, +) +``` +Pass `reqLog` to sub-handlers instead of using the global `slog`.

Testing: WebSocket Integration Test Patterns + +### Current State +Tests use `NewTestClient` with bare send channels — functional but doesn't test the actual WebSocket upgrade, serialization, or connection lifecycle. + +### What Production Platforms Do +Matrix's Dendrite has a `test.Server` that starts a real HTTP server, upgrades to WebSocket, and runs scenarios end-to-end. Mumble has protocol-level integration tests. + +### Recommendation +Add a thin integration test layer: +1. Start a test HTTP server with `httptest.NewServer` +2. Connect via real WebSocket (`nhooyr.io/websocket.Dial`) +3. Send auth message, receive `auth_ok` + `ready` +4. Run message send/receive scenarios +5. Test reconnection and error paths + +This catches serialization bugs, protocol violations, and concurrency issues that unit tests with mock channels miss. Keep existing unit tests as-is — add this as a separate `_integration_test.go` file. + +--- + +## 14. Client: TypeScript Strict Mode Enforcement + +### Current State +The client uses TypeScript but some patterns (like `as unknown as` casts in ws.ts listener registry) bypass type safety. + +### What Production Platforms Do +Element Web uses strict TypeScript with `"strict": true` and avoids `any` types. Revolt's client also enforces strict mode. + +### Recommendation +- Audit `tsconfig.json` for `"strict": true`, `"noUncheckedIndexedAccess": true` +- Replace `as unknown as` casts with proper generics or discriminated union narrowing +- The ws.ts listener registry can use a generic `Map<T, Set<WsListener<T>>>` pattern that avoids casts entirely +- Replace `map[string]any` equivalent patterns (`Record<string, unknown>`) with typed interfaces + +--- + +## Key Takeaways (Priority Order) + +1. **Message sequence numbers + replay on reconnect** (#7, #11) — highest-impact reliability improvement; every major platform does this +2. **Typed message structs in Go** (#3) — eliminates an entire class of silent protocol bugs +3. **Virtual scrolling for messages** (#6) — prevents performance degradation as conversations grow +4. **Disposable component pattern** (#5) — systematic prevention of memory leaks +5. **SQLite pragma tuning** (#9) — free performance gains with no code changes +6. **Sentinel errors** (#1) — cleaner error handling, better testability +7. **Structured logging levels** (#2) — reduces noise, improves debuggability +8. **Request-scoped logging** (#12) — makes production debugging tractable +9. **Graceful shutdown** (#4) — prevents data loss during server restarts +10. **Server-side heartbeat monitoring** (#8) — detects ghost connections faster +11. **Store subscription efficiency** (#10) — reduces wasted re-renders +12. **WebSocket integration tests** (#13) — catches serialization/protocol bugs +13. **TypeScript strict mode** (#14) — catches type errors at compile time +14. **Heartbeat improvements** (#8) — bidirectional liveness detection + +--- + +## Sources + +1.

Return channel info + +#### `GET /api/v1/dms` + +List the authenticated user's open DM channels. + +**Response:** `{ "dm_channels": [ { "channel_id": 99, "recipient": {...}, "last_message": "Hey!", "last_message_at": "2026-03-27T14:00:00Z", "unread_count": 2 }, ... ] }` + +**Logic:** Call `GetUserDMChannels(authUserId)`, ordered by most recent message. + +#### `DELETE /api/v1/dms/{channelId}` + +Close a DM (hide from sidebar). Messages are preserved. + +**Logic:** +1. Verify user is a DM participant +2. Call `CloseDM(authUserId, channelId)` +3. Return 204 + +### Modified endpoint + +#### `GET /api/v1/channels/{id}/messages` + +Add a permission check: if the channel `type == 'dm'`, verify the requesting user is a participant via `IsDMParticipant()`. Otherwise use the existing role-based permission check. + +#### `POST /channels/{id}/typing` (WebSocket `typing` event) + +Same DM participant check. Typing indicators work in DMs with no code changes beyond the permission gate. + +--- + +## 4. Server: WebSocket Changes + +### Message routing for DM channels + +In `hub.go`, when broadcasting a message for a DM channel (`type == 'dm'`): +- Instead of `BroadcastToChannel()` (which checks channel subscriptions), use `SendToUser()` for each of the two participants +- This ensures both users receive the message regardless of which channels they've "joined" + +### Modified: `handleChatSend` + +When the target channel is a DM: +1. Check `IsDMParticipant()` instead of `requireChannelPerm()` +2. After persisting the message, auto-reopen the DM for the recipient if closed (insert into `dm_open_state`) +3. If reopened, send a `dm_channel_open` event to the recipient +4. Broadcast using `SendToUser()` to both participants + +### New WebSocket events + +#### `dm_channel_open` (server → client) + +Sent when a DM is opened or auto-reopened for a user. + +```json +{ + "type": "dm_channel_open", + "payload": { + "channel_id": 99, + "recipient": { "id": 42, "username": "Player1", "avatar": "", "status": "online" } + } +} +``` + +#### `dm_channel_close` (server → client) + +Sent when a user closes a DM (confirmation of the DELETE request). + +```json +{ + "type": "dm_channel_close", + "payload": { + "channel_id": 99 + } +} +``` + +### Modified: `ready` payload + +Add `dm_channels` array to the ready payload: + +```json +{ + "type": "ready", + "payload": { + "user": { ... }, + "channels": [ ... ], + "dm_channels": [ + { + "channel_id": 99, + "recipient": { "id": 42, "username": "Player1", "avatar": "", "status": "online" }, + "last_message_id": 1234, + "last_message": "Hey!", + "last_message_at": "2026-03-27T14:00:00Z", + "unread_count": 2 + } + ], + "members": [ ... ] + } +} +``` + +--- + +## 5.

Client: Sidebar Integration + +### DM section in channel mode + +The "DIRECT MESSAGES" section in the sidebar reads from `dmStore` instead of guessing from online members. Shows: +- All open DMs (including offline users) +- Last message preview + timestamp +- Unread badge +- Click to enter DM mode for that channel + +### DM mode sidebar + +When in DM mode, the `DmSidebar` component shows all open DMs from the store. The selected DM loads messages via `getMessages(channelId)`. + +### "New DM" flow + +The "+" button next to "DIRECT MESSAGES": +1. Opens a member picker (all server members, including offline) +2. Selecting a user calls `createDm(userId)` +3. Server returns the channel_id +4. Client switches to DM mode with that channel active +5. Messages load via existing `getMessages(channelId)` + +### Auto-reopen + +When a `dm_channel_open` event arrives (someone messaged you in a closed DM), the client adds it to the DM store and shows the unread badge.

Client: Message Loading in DM Mode + +When the user selects a DM conversation: +1. `setActiveDmUser(recipientId)` + `setSidebarMode("dms")` +2. The chat area's `ChannelController` loads messages for the DM `channelId` — this is the same `switchChannel(channelId)` call used for regular channels +3. Typing, reactions, pins, message editing — all work automatically because they're keyed on `channelId` +4. The ChatHeader shows `@Username` instead of `#channel-name` + +--- + +## 9.
