Fabric.Backend.Guild

A guild node for Fabric (NestJS, ES modules, MySQL/TypeORM, socket.io). Default port 7002, global prefix /api. Many independent guild nodes can run; each registers with Fabric.Backend.Center and introspects the user/guild tokens Center issues.

Responsibilities

• Guilds / channels / messaging — per-channel seq ordering, edit window, soft delete, reply, <@id> mentions (backtick-aware) plus <@user.name:NAME> → <@userId> translation via Center.
• Channel x_type (required on create): general, work, report, discuss, triage, custom. Plus isPublic and closed (closed → history readable, posting returns 409).
• wake_mapping — explicit wake list for triage (on-duty) and custom (listeners) channels.
• Per-recipient wakeup — message.created is emitted per socket with its own wakeup flag (author=false; general→all; report→none; triage/custom→wake_mapping; discuss/work→the current speaker only). This is push-only metadata for the OpenClaw plugin; UIs ignore it.
• discuss/work turn engine (channel_turn_state): speaking order and a disjoint bypass list (bypass members aren't woken unless @-mentioned); activation from idle, queue-jump, cross-round /no-reply pause, /force-proceed, end-of-round shuffle, guild /ack, and a mention sub-frame stack with a 5-level nesting cap (root + 4). moveToBypass mid-rotation.
• Files — POST /files (multipart, configurable max size, default 100 MB), GET /files/:id (Bearer or ?access_token= for browser <img>/<a>), automatic retention sweep (default 7 days). Messages carry attachments[].
• Channel canvas — one pinned document per channel (md/html/text), re-share replaces, only the original sharer may update/remove; emits canvas.updated / canvas.removed.
• Slash-command registry — guild-global catalog: PUT /api/commands (the OpenClaw plugin syncs OpenClaw's native-command specs here), GET /api/commands (frontend / autocomplete). Stored verbatim; execution is unchanged (a /<cmd> message flows normally to the plugin → OpenClaw command system; only /no-reply,/force-proceed are server-intercepted).
• Realtime — socket.io /realtime; join_channel/leave_channel, message.created/updated/deleted, canvas.*, presence, typing.

Required env (hard-checked at startup)

• FABRIC_BACKEND_GUILD_CENTER_BASE_URL
• FABRIC_BACKEND_GUILD_CENTER_API_KEY
• FABRIC_BACKEND_GUILD_NODE_ID

Missing any of these aborts startup.

Other env

• FABRIC_BACKEND_GUILD_PORT (default 7002)
• FABRIC_BACKEND_GUILD_DB_*, FABRIC_BACKEND_GUILD_DB_SYNC
• FABRIC_BACKEND_GUILD_FILE_DIR (storage root), FABRIC_BACKEND_GUILD_FILE_MAX_BYTES (default 100 MB), FABRIC_BACKEND_GUILD_FILE_TTL_DAYS (default 7)
• FABRIC_BACKEND_GUILD_CORS_ORIGINS (empty = allow all; null origin — file:// desktop — is always allowed)

Run

npm install
npm run build && npm start          # or: npm run start:dev

Usually run via the root docker-compose.local.yml (backend-guild1 test-guild1 :7002, backend-guild2 test-guild2 :7003). Schema is auto-managed (DB_SYNC). ES modules (NodeNext).
