# Tasks: enterprise-api-plugin-messaging

**Change ID**: enterprise-api-plugin-messaging
**Package**: `@suaveplan/api-plugin-messaging`
**Target path**: `api/comms/api-plugin-messaging`
**Prerequisite packages on Verdaccio**: `@suaveplan/api`, `@suaveplan/api-shared`, `@suaveplan/api-plugin-auth`, `@suaveplan/api-plugin-database`, `@suaveplan/api-plugin-file-upload`, `@suaveplan/api-plugin-notifications`, `@suaveplan/suppression`, `@suaveplan/events`, `@suaveplan/rate-limiter`, `@suaveplan/error`

## 0. Pre-flight (non-negotiable)

- [ ] 0.1 Confirm clean working tree (`git status` reports nothing) and no in-flight worktrees with uncommitted work (`git worktree list` then `git status` in each)
- [ ] 0.2 If any worktrees exist under `.claude/worktrees/`, account for each one: still-active agent, work-pending-merge, or stale-and-prune. Stale worktrees MUST be removed (`git worktree remove`) before opening a new one — code that has been lost twice on main is the failure mode this guards against.
- [ ] 0.3 Confirm the package set in `MANIFEST.md` matches `find packages -maxdepth 3 -name package.json` count. Drift here means a prior change archived without regenerating the manifest.

## 1. Scaffold + types + errors + events

- [ ] Create `api/comms/api-plugin-messaging/`; `package.json` v0.0.0; standard tooling.
- [ ] Types: `Thread`, `ThreadParticipant`, `Message`, `Reaction`, `ReadReceipt`, `MessagingPluginConfig` (Zod).
- [ ] Errors: 6-code union + metadata + registration. Test + doc.
- [ ] Events: `MessagingEventMap` (messaging:message:sent, messaging:thread:created, messaging:message:deleted, messaging:reaction:added).

---

## 2. SurrealQL

- [ ] `thread.surql`, `thread_participant.surql`, `message.surql`, `reaction.surql`, `read_receipt.surql`. tenantId indexes; full-text on message content.

---

## 3. Services (each `.test.ts` + `.md`)

- [ ] **ThreadService**: `createThread` (1:1 or group), `getThread`, `listThreads`, `addParticipant`, `removeParticipant`.
- [ ] **MessageService**: `sendMessage` (check suppression list), `editMessage`, `deleteMessage`, `listMessages` (paginated), `markRead`. Rate-limit on send. Notify via `api-plugin-notifications` on unread message.
- [ ] **ReactionService**: `addReaction`, `removeReaction`, `listReactions`.
- [ ] **ModerationService**: `flagMessage`, `deleteMessageAdmin`, `banParticipant`.

---

## 4. Routes

- [ ] `GET/POST /messaging/threads` — `requireAuth`.
- [ ] `GET /messaging/threads/:id`, `GET/POST /messaging/threads/:id/messages` — `requireAuth`.
- [ ] `POST /messaging/threads/:id/read` — `requireAuth`.
- [ ] `POST /messaging/threads/:id/reactions` — `requireAuth` + rate-limit.
- [ ] Route `.test.ts` + `.md`.

---

## 5. Plugin factory + integration tests + publish

- [ ] `createMessagingPlugin`: `definePlugin`, `dependencies: ["database", "auth"]`, `migrationsPath: "./surql"`.
- [ ] Integration: create thread → send message → read receipt → notification triggered (real SurrealDB).
- [ ] `bunx turbo lint typecheck test --filter=@suaveplan/api-plugin-messaging` — green; 100% coverage.
- [ ] `bun scripts/publish.ts --package @suaveplan/api-plugin-messaging`.
- [ ] Archive → `openspec/archive/2026-04-24-enterprise-api-plugin-messaging/`.
