7+
8+
---
9+
10+
## Requirements Delivered
11+
12+
### ✅ 1. Update Endpoint
13+
- **Route:** `PATCH /admin/waitlist/:id`
14+
- **Functionality:** Update wallet_address, email_address, or telegram_username
15+
- **Validation:** At least one field required, duplicate checking
16+
- **Security:** Admin-only, JWT auth, rate limited (30/min)
17+
- **Audit:** Logs all changes with admin ID, IP, and details
18+
19+
### ✅ 2. Delete Endpoint
20+
- **Soft Delete:** `DELETE /admin/waitlist/:id`
21+
- Marks entry as deleted (sets deleted_at timestamp)
22+
- Entry remains in database for recovery
23+
- Rate limited (30/min)
24+
25+
- **Hard Delete:** `DELETE /admin/waitlist/:id/permanent`
26+
- Permanently removes from database
27+
- More restrictive rate limit (10/min)
28+
- Use with caution
29+
30+
### ✅ 3. Soft Delete Support
31+
- Added `deleted_at` column to waitlist table
32+
- Uses TypeORM's `@DeleteDateColumn` decorator
33+
- Soft-deleted entries automatically excluded from queries
34+
- Migration created and ready to run
35+
36+
### ✅ 4. Audit Logs
37+
- Integrated with existing AdminLogsService
38+
- Tracks: admin ID, action type, target ID, changes, IP, user agent, timestamp
39+
- Action types: `waitlist:update`, `waitlist:soft_delete`, `waitlist:hard_delete`
40+
- Full accountability and traceability
41+
42+
---
43+
44+
## Acceptance Criteria Met
45+
46+
### ✅ Only admins can modify data
47+
- All endpoints protected by `JwtAuthGuard` and `AdminGuard`
48+
- Rate limiting prevents abuse
49+
- Proper HTTP status codes for unauthorized access (401, 403)
50+
51+
### ✅ Changes tracked
52+
- Every modification logged to `admin_logs` table
53+
- Includes who, what, when, where (IP), and how (user agent)
54+
- Can query logs to audit all waitlist changes
55+
