# P0: Implementation Checklist

# P0 Implementation Checklist — Drop Support Systems

**Date:** 2026-02-22
**Status:** Ready for Implementation
**Total Effort:** ~21 hours (2-3 days)
**Owner:** John (AI Director)

---

## Overview

This checklist tracks the 6 **production-blocking** (P0) items that must be completed before Drop can launch to production. Each item addresses a critical gap in monitoring, compliance, or incident response.

---

## P0 Items

### 1. Server-Side Error Tracking ⏱️ 2 hours (revised)

**Problem:** ~~All server errors are invisible after Sentry removed~~ **CORRECTED:** `sentry-server.ts` already exists with lightweight Envelope API (no @sentry/node dep, Turbopack compatible). However, only 5/25+ routes have `captureServerError` integrated.

**Status:** 🟡 Partially Complete (library done, coverage gaps)

**Tasks:**
- [x] ~~Research Sentry Edge SDK compatibility~~ Already solved: custom Envelope API
- [x] ~~Install and configure~~ `src/lib/sentry-server.ts` already complete
- [x] ~~Update sentry-server.ts~~ Already has captureServerError + captureServerMessage
- [ ] **Expand captureServerError to ALL API routes** (currently only 5 routes)
- [ ] Test: Trigger 500 error in expanded routes, verify Sentry event
- [ ] Configure source maps upload (optional but recommended)

**Deliverables:**
- ✅ `src/lib/sentry-server.ts` (already complete — Envelope API, no SDK dep)
- ✅ Integrated in: bankid, bankid/callback, qr-payment, remittance, health
- 🔨 Expanding to: all remaining API routes (~20 routes)

**Acceptance Criteria:**
- ALL API routes have captureServerError in catch blocks
- Error includes context tags (endpoint name, userId)

---

### 2. Audit Logging System ⏱️ 0 hours (ALREADY COMPLETE)

**Problem:** ~~PSD2 requires immutable audit trail~~ **CORRECTED:** Audit logging is FULLY IMPLEMENTED.

**Status:** ✅ Complete

**What exists:**
- [x] `src/lib/audit.ts` — Full audit library with 30+ action types, logAudit(), getAuditLog(), countAuditEntries()
- [x] `audit_log` table in DB schema (initial migration + db.ts fallback)
- [x] Indexes on user_id, timestamp, action
- [x] 5-year retention documented (data-retention.ts explicitly excludes audit_log from cleanup)
- [x] Fire-and-forget pattern (doesn't block user actions)
- [x] Integrated in 20+ API routes: auth, transactions, cards, recipients, settings, consents, complaints, user management, GDPR endpoints
- [x] Admin audit export: `/api/admin/audit/` endpoint exists
- [x] GDPR data export: `/api/user/data-export/` includes audit log
- [x] Structured logger also captures audit events (stdout for CloudWatch)

**No action needed.** This was incorrectly flagged as missing in the initial analysis.

---

### 3. WAF Deployment ⏱️ 2 hours

**Problem:** WAF rules defined but not enforced (requires reverse proxy).

**Status:** ⬜ Not Started

**Tasks:**
- [ ] Review `infrastructure/waf-rules.md` for required rules
- [ ] Configure Cloudflare WAF (recommended):
  - [ ] Enable SQLi protection
  - [ ] Enable XSS protection
  - [ ] Enable path traversal blocking
  - [ ] Set request size limits (1MB API, 10KB auth)
- [ ] OR configure AWS WAF (alternative):
  - [ ] Create WAF web ACL
  - [ ] Associate with App Runner service
- [ ] Test WAF rules:
  - [ ] Send SQLi payload (`?id=1' OR '1'='1`), expect 403
  - [ ] Send XSS payload (`<script>alert(1)</script>`), expect 403
- [ ] Document deployment steps

**Deliverables:**
- ✅ `infrastructure/cloudflare-waf-setup.md` (to be created)
- ⬜ Cloudflare WAF configured
- ⬜ Test results documented

**Acceptance Criteria:**
- SQLi attacks blocked with 403
- XSS attacks blocked with 403
- Legitimate requests pass through
- WAF logs visible in Cloudflare dashboard

---

### 4. Log Aggregation & Retention ⏱️ 2 hours

**Problem:** Structured logs write to stdout but aren't retained or searchable.

**Status:** ⬜ Not Started

**Tasks:**
- [ ] Set CloudWatch Logs retention policy:
  - [ ] Production: 30 days
  - [ ] Staging: 7 days
- [ ] Create CloudWatch Log Insights queries:
  - [ ] All errors (last hour)
  - [ ] User activity trace
  - [ ] Request trace by ID
  - [ ] API endpoint performance (slow queries)
  - [ ] Authentication events
  - [ ] Payment failures
- [ ] Create CloudWatch alarms:
  - [ ] High error rate (>10/min)
  - [ ] No logs received (service down)
  - [ ] Database errors (>5 in 5 min)
- [ ] Create SNS topic for alerts
- [ ] Subscribe email/Slack to SNS topic
- [ ] Test alarms (trigger error spike, verify alert)

**Deliverables:**
- ✅ `infrastructure/cloudwatch-logs-setup.md` (created)
- ⬜ CloudWatch retention policies set
- ⬜ Log Insights queries saved
- ⬜ CloudWatch alarms active

**Acceptance Criteria:**
- Logs retained for 30 days (production)
- Log Insights queries return results in <5 seconds
- Error spike triggers Slack alert within 2 minutes
- Service downtime triggers alert within 5 minutes

---

### 5. External Uptime Monitoring ⏱️ 1 hour

**Problem:** BetterStack documented but not deployed.

**Status:** ⬜ Not Started

**Tasks:**
- [ ] Sign up for BetterStack (free tier)
- [ ] Create monitors:
  - [ ] Production health: `https://9ef3szvvsb.eu-west-1.awsapprunner.com/api/health`
    - Interval: 3 minutes
    - Keyword check: `"status":"ok"`
  - [ ] Staging health: `https://drop-staging.fly.dev/api/health`
  - [ ] Landing page: `https://getdrop.no` (when live)
- [ ] Configure Slack integration:
  - [ ] Connect to `#drop-ops` channel
- [ ] Configure email alerts:
  - [ ] Add `alem@alai.no`
- [ ] Test monitoring:

## Dependencies

### External Dependencies
- BetterStack account signup (5 min, no approval needed)
- Sentry organization/project (existing, or create new)
- Cloudflare account (existing for DNS, WAF is free tier)

### Internal Dependencies
- Alem approval for:
  - Audit log schema changes
  - CloudWatch cost ($17/month estimate)
  - BetterStack Pro upgrade (optional, $20/month for 30s interval)

### Blocked Items
- Some runbooks require Phase 2 context (real banking integrations)
  - Can document procedures but can't fully test without live APIs
  - Mark as "draft" until Phase 2

---

## Testing Plan

### Test 1: Error Tracking
```bash
# Trigger server error
curl -X POST http://localhost:3000/api/test/error \
  -H "Content-Type: application/json" \
  -d '{"trigger":"server_error"}'

# Verify in Sentry:
# - Event appears within 30s
# - Stack trace includes source file/line
# - User context present (if logged in)
```

### Test 2: Audit Logging
```bash
# Perform audit-worthy action
curl -X POST http://localhost:3000/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{"email":"test@example.com","password":"wrong"}'

# Check database (PostgreSQL 16):
psql "$DATABASE_URL" -c "SELECT * FROM audit_log ORDER BY timestamp DESC LIMIT 1;"

# Expected:
# audit_xxx|2026-02-22T10:00:00Z|usr_123|login_failure|...|1.2.3.4|Mozilla...
```

### Test 3: WAF
```bash
# Test SQLi blocking
curl "https://getdrop.no/api/test?id=1' OR '1'='1" -v

# Expected: HTTP 403 Forbidden

# Test legitimate request
curl "https://getdrop.no/api/health" -v

# Expected: HTTP 200 OK
```

### Test 4: CloudWatch Alarms
```bash
# Trigger error spike (loop 15 errors)
for i in {1..15}; do
  curl http://localhost:3000/api/test/error
  sleep 2
done

# Expected:
# - CloudWatch alarm fires after 2 minutes (2 x 1min periods)
# - Slack alert received in #drop-ops
# - Email sent to alem@alai.no
```

### Test 5: BetterStack
```bash
# Stop app
docker stop drop-app

# Wait 3-5 minutes

# Expected:
# - BetterStack detects downtime
# - Slack alert in #drop-ops
# - Email to alem@alai.no

# Restart app
docker start drop-app

# Expected:
# - BetterStack detects recovery
# - "UP" notification sent
```

---

## Rollout Plan

### Phase 1: Non-Intrusive (Day 1)
- External monitoring (BetterStack)
- CloudWatch retention policies
- CloudWatch alarms (passive, alerts only)

**Risk:** None. These are read-only additions.

### Phase 2: Database Changes (Day 2)
- Audit log schema migration
- Audit log library (no integrations yet)

**Risk:** Low. New table, no app changes. Test migration in dev first.

### Phase 3: Code Integration (Day 3-4)
- Audit logging in auth endpoints
- Server-side error tracking (Sentry edge)
- WAF deployment

**Risk:** Medium. Requires code changes + deployment. Deploy to staging first, test 24h, then production.

### Phase 4: Runbooks (Day 5)
- Complete remaining runbooks
- Team training session
- Runbook testing in staging

**Risk:** None. Documentation only, no production changes.

---

## Success Metrics

**After P0 completion, we should achieve:**
- ✅ 100% server errors visible (Sentry events)
- ✅ 100% audit events logged (auth, admin, data access)
- ✅ >99.9% uptime detection (BetterStack)
- ✅ <5 min MTTD (mean time to detect incidents)
- ✅ <15 min MTTR (mean time to recover, using runbooks)
- ✅ 0 security vulnerabilities from WAF bypass

---
