1# Role-Based Permission System Implementation Plan (ATB-17)
2
3> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
4
5**Goal:** Implement role-based access control with 4 default roles (Owner, Admin, Moderator, Member) enforced via middleware on all write operations.
6
7**Architecture:** Three-layer system - (1) Database + Indexer for role storage, (2) Permission middleware + helpers for enforcement, (3) Admin endpoints for role management. Follows existing patterns (factory functions, AppContext DI, TDD).
8
9**Tech Stack:** TypeScript, Hono, Drizzle ORM, PostgreSQL, Vitest, AT Protocol SDK
10
11**Design Document:** See `docs/plans/2026-02-14-permissions-design.md` for full design rationale.

15## Task 1: Database Schema - Roles Table
16
17**Files:**
18- Create: `packages/db/drizzle/migrations/0004_add_roles_table.sql`
19- Modify: `packages/db/src/schema.ts:178-210` (add roles table export)
20
21**Step 1: Create migration SQL**
22
23Create migration file with roles table definition:
24
25```bash
26# File: packages/db/drizzle/migrations/0004_add_roles_table.sql
27CREATE TABLE roles (
28 id BIGSERIAL PRIMARY KEY,
29 did TEXT NOT NULL,
30 rkey TEXT NOT NULL,
31 cid TEXT NOT NULL,
32 name TEXT NOT NULL,
33 description TEXT,
34 permissions TEXT[] NOT NULL DEFAULT '{}',
35 priority INTEGER NOT NULL,
36 created_at TIMESTAMP WITH TIME ZONE NOT NULL,
37 indexed_at TIMESTAMP WITH TIME ZONE NOT NULL,
38 UNIQUE(did, rkey)
39);
40
41CREATE INDEX idx_roles_did ON roles(did);
42CREATE INDEX idx_roles_did_name ON roles(did, name);
43```
44
45**Step 2: Add roles table to schema**
46
47Modify `packages/db/src/schema.ts` after `firehoseCursor` table (line 188):
48
49```typescript
50// ── roles ───────────────────────────────────────────────
51// Role definitions, owned by Forum DID.
52export const roles = pgTable(
53 "roles",
54 {
55 id: bigserial("id", { mode: "bigint" }).primaryKey(),
56 did: text("did").notNull(),
57 rkey: text("rkey").notNull(),
58 cid: text("cid").notNull(),
59 name: text("name").notNull(),
60 description: text("description"),
61 permissions: text("permissions").array().notNull().default(sql`'{}'::text[]`),
62 priority: integer("priority").notNull(),
63 createdAt: timestamp("created_at", { withTimezone: true }).notNull(),
64 indexedAt: timestamp("indexed_at", { withTimezone: true }).notNull(),
65 },
66 (table) => [
67 uniqueIndex("roles_did_rkey_idx").on(table.did, table.rkey),
68 index("roles_did_idx").on(table.did),
69 index("roles_did_name_idx").on(table.did, table.name),
70 ]
71);
72```
73
74Also add `sql` import at top:
75
76```typescript
77import {
78 pgTable,
79 bigserial,
80 text,
81 timestamp,
82 integer,
83 boolean,
84 bigint,
85 uniqueIndex,
86 index,
87 sql, // ADD THIS
88} from "drizzle-orm/pg-core";
89```
90
91**Step 3: Run migration**
92
93```bash
94cd packages/db
95pnpm db:migrate
96```
97
98Expected: Migration runs successfully, `roles` table created in database.
99
100**Step 4: Verify schema in database**
101
102```bash
103psql $DATABASE_URL -c "\d roles"
104```
105
106Expected: Shows table structure with all columns and indexes.
107
108**Step 5: Commit**
109
110```bash
111git add packages/db/drizzle/migrations/0004_add_roles_table.sql packages/db/src/schema.ts
112git commit -m "feat(db): add roles table for permission system
113
114- Create roles table with permissions array and priority field
115- Add indexes on did and did+name for efficient lookups
116- Migration 0004_add_roles_table.sql"
117```
118

121## Task 2: Update Test Cleanup
122
123**Files:**
124- Modify: `apps/appview/src/lib/__tests__/test-context.ts:45-60` (add roles cleanup)
125
126**Step 1: Add roles to cleanup**
127
128In `test-context.ts`, add roles cleanup after `modActions` cleanup (around line 55):
129
130```typescript
131// Clean up test data
132await db.delete(modActions).where(eq(modActions.did, config.forumDid));
133await db.delete(roles).where(eq(roles.did, config.forumDid)); // ADD THIS
134await db.delete(posts).where(eq(posts.forumUri, forumUri));
135```
136
137Also add roles import at top:
138
139```typescript
140import {
141 forums,
142 categories,
143 boards,
144 posts,
145 users,
146 memberships,
147 modActions,
148 roles, // ADD THIS
149 firehoseCursor,
150} from "@atbb/db";
151```
152
153**Step 2: Commit**
154
155```bash
156git add apps/appview/src/lib/__tests__/test-context.ts
157git commit -m "test: add roles table to test cleanup"
158```
159
160---
161
162## Task 3: Role Indexer
163
164**Files:**
165- Modify: `apps/appview/src/lib/indexer.ts:1-30` (add import)
166- Modify: `apps/appview/src/lib/indexer.ts:70-150` (add roleConfig)
167- Modify: `apps/appview/src/lib/indexer.ts:450-500` (add handler methods)
168- Modify: `apps/appview/src/lib/indexer.ts:600-650` (register handlers)
169
170**Step 1: Add Role import**
171
172At top of `indexer.ts`, add to lexicon imports (around line 23):
173
174```typescript
175import {
176 SpaceAtbbPost as Post,
177 SpaceAtbbForumForum as Forum,
178 SpaceAtbbForumCategory as Category,
179 SpaceAtbbForumBoard as Board,
180 SpaceAtbbMembership as Membership,
181 SpaceAtbbModAction as ModAction,
182 SpaceAtbbForumRole as Role, // ADD THIS
183} from "@atbb/lexicon";
184```
185
186**Step 2: Add roleConfig after boardConfig**
187
188After `boardConfig` definition (around line 250), add:
189
190```typescript
191private roleConfig: CollectionConfig<Role.Record> = {
192 name: "Role",
193 table: roles,
194 deleteStrategy: "hard",
195 toInsertValues: async (event, record) => ({
196 did: event.did,
197 rkey: event.commit.rkey,
198 cid: event.commit.cid,
199 name: record.name,
200 description: record.description || null,
201 permissions: record.permissions,
202 priority: record.priority,
203 createdAt: new Date(record.createdAt),
204 indexedAt: new Date(),
205 }),
206 toUpdateValues: async (event, record) => ({
207 cid: event.commit.cid,
208 name: record.name,
209 description: record.description || null,
210 permissions: record.permissions,
211 priority: record.priority,
212 indexedAt: new Date(),
213 }),
214};
215```
216
217**Step 3: Add handler methods**
218
219After other handler methods (around line 450), add:
220
221```typescript
222async handleRoleCreate(event: CommitCreateEvent<Role.Record>) {
223 await this.genericCreate(this.roleConfig, event);
224}
225
226async handleRoleUpdate(event: CommitUpdateEvent<Role.Record>) {
227 await this.genericUpdate(this.roleConfig, event);
228}
229
230async handleRoleDelete(event: CommitDeleteEvent) {
231 await this.genericDelete(this.roleConfig, event);
232}
233```
234
235**Step 4: Register handlers**
236
237In `createHandlerRegistry()`, after board registration (around line 650), add:
238
239```typescript
240.register({
241 collection: "space.atbb.forum.role",
242 onCreate: this.createWrappedHandler("handleRoleCreate"),
243 onUpdate: this.createWrappedHandler("handleRoleUpdate"),
244 onDelete: this.createWrappedHandler("handleRoleDelete"),
245})
246```
247
248**Step 5: Commit**
249
250```bash
251git add apps/appview/src/lib/indexer.ts
252git commit -m "feat(indexer): add role indexer for space.atbb.forum.role
253
254- Add roleConfig with hard delete strategy
255- Implement handleRoleCreate, handleRoleUpdate, handleRoleDelete
256- Register handlers in createHandlerRegistry"
257```

1855cd apps/appview
1856pnpm dev
1857```
1858
1859Expected: Logs show "Created default role" for 4 roles.
1860
1861**Step 3: Verify roles in database**
1862
1863```bash
1864psql atbb_dev -c "SELECT name, priority, array_length(permissions, 1) as perm_count FROM roles ORDER BY priority;"
1865```
1866
1867Expected:
1868```
1869 name | priority | perm_count
1870----------+----------+------------
1871 Owner | 0 | 1
1872 Admin | 10 | 9
1873 Moderator| 20 | 6
1874 Member | 30 | 2
1875```
1876
1877**Step 4: Test permission enforcement**
1878
1879Try creating a topic without a role (should fail with 403):
1880
1881```bash
1882# This requires setting up OAuth first - defer to integration tests
1883```
1884
1885**Step 5: Document manual testing completion**
1886
1887Manual testing checklist completed - basic seeding and database setup verified.

Files: `apps/appview/src/middleware/permissions.ts`, `apps/appview/src/routes/admin.ts`, `apps/appview/src/lib/seed-roles.ts`, `packages/db/src/schema.ts:188-210` (2026-02-14)
1902- [x] Middleware: permission checks on write endpoints — **Complete:** `requirePermission()` and `requireRole()` middleware integrated on all write endpoints (`POST /api/topics`, `POST /api/posts`). Future mod endpoints will use `canActOnUser()` for priority hierarchy enforcement.

1964## Success Criteria Checklist
1965
1966Verify all success criteria are met:
1967
1968- [ ] Only users with `createTopics` permission can create topics
1969- [ ] Only users with `createPosts` permission can create posts
1970- [ ] Admins can assign roles to members via `POST /api/admin/members/:did/role`
1971- [ ] Priority hierarchy prevents privilege escalation (Admin can't assign Admin/Owner roles)
1972- [ ] Permission checks complete in <10ms (database indexes in place)
1973- [ ] Default roles seeded automatically on fresh install
1974- [ ] All tests passing (100% coverage on permission logic)

1992## Future Enhancements (ATB-19+)
1993
1994This implementation provides the foundation for:
1995
1996- **ATB-19:** Moderation action write-path endpoints (will use `canActOnUser()` for priority enforcement)
1997- **ATB-20:** Moderation action indexing
1998- **ATB-21:** Ban enforcement
1999- **ATB-22:** Content visibility filtering
2000- **Post-MVP:** Permission caching, custom roles, per-category permissions
