docs: add Alpha Go-Live PRD and JWT verification test

Add comprehensive Alpha launch readiness documentation and production
JWT verification testing infrastructure.

**Alpha Go-Live PRD** (docs/PRD_ALPHA_GO_LIVE.md):
- Track remaining work for alpha launch with real users
- P0 blockers: DPoP architecture fix, JWT verification (2 items)
- ✅ Validated handle resolution already implemented
- ✅ Validated comment_count reconciliation already implemented
- P1 infrastructure: Monitoring, logging, backups, load testing
- E2E testing recommendations (7 critical gaps identified)
- Timeline: 65-80 hours (~2-3 weeks)
- Go/no-go decision criteria and risk assessment

**JWT Verification Test** (tests/integration/jwt_verification_test.go):
- E2E test for JWT signature verification with real PDS
- Tests JWT parsing, JWKS fetching, and auth middleware
- Validates AUTH_SKIP_VERIFY=false production mode
- Handles both dev PDS (symmetric) and production PDS (JWKS)
- Tests tampered token rejection

Changes support alpha launch planning and production security validation.

+
+
## P0: Critical Blockers (Must Complete Before Alpha)
+
+

+
---
+
+
## Testing Gaps
+
+
### E2E Testing Recommendations
+
+
#### 1. Full User Journey Test (CRITICAL)
+
**What**: Test complete user flow from signup to interaction
+
**Why**: No single test validates the entire happy path
+
+
- [ ] Create test: Signup → Authenticate → Create Community → Create Post → Add Comment → Vote
+
- [ ] Verify all data flows through Jetstream correctly
+
- [ ] Verify counts update (vote counts, comment counts, subscriber counts)
+
- [ ] Verify timeline feed shows posts from subscribed communities
+
- [ ] Test with 2+ users interacting (user A posts, user B comments)
+
+
**File**: Create `tests/integration/user_journey_e2e_test.go`
+
**Estimated Effort**: 4-6 hours
+
+
#### 2. Blob Upload E2E Test
+
**What**: Test image upload and display in posts
+
**Why**: No test validates the full blob upload → post → feed display flow
+
+
- [ ] Create post with embedded image
+
- [ ] Verify blob uploaded to PDS
+
- [ ] Verify blob URL transformation in feed responses
+
- [ ] Test multiple images in single post
+
- [ ] Test image in comment
+
+
**Estimated Effort**: 3-4 hours
+
+
#### 3. Multi-Community Timeline Test
+
**What**: Test timeline feed with multiple community subscriptions
+
**Why**: Timeline logic may have edge cases with multiple sources
+
+
- [ ] Create 3+ communities
+
- [ ] Subscribe user to all communities
+
- [ ] Create posts in each community
+
- [ ] Verify timeline shows posts from all subscribed communities
+
- [ ] Verify hot/top/new sorting across communities
+
+
**Estimated Effort**: 2-3 hours
+
+
#### 4. Concurrent User Scenarios
+
**What**: Test system behavior with simultaneous users
+
**Why**: Race conditions and locking issues only appear under concurrency
+
+
- [ ] Multiple users voting on same post simultaneously
+
- [ ] Multiple users commenting on same post simultaneously
+
- [ ] Community creation with same handle (should fail)
+
- [ ] Subscription race conditions
+
+
**Estimated Effort**: 4-5 hours
+
+
#### 5. Rate Limiting Tests
+
**What**: Verify rate limits work correctly
+
**Why**: Protection against abuse
+
+
- [ ] Test aggregator rate limits (already exists)
+
- [ ] Test general endpoint rate limits (100 req/min)
+
- [ ] Test comment rate limits (20 req/min)
+
- [ ] Verify 429 responses
+
- [ ] Verify rate limit headers
+
+
**Estimated Effort**: 2-3 hours
+
+
#### 6. Error Recovery Tests
+
**What**: Test system recovery from failures
+
**Why**: Production will have failures
+
+
- [ ] Jetstream reconnection after disconnect
+
- [ ] PDS temporarily unavailable during post creation
+
- [ ] Database connection loss and recovery
+
- [ ] Malformed Jetstream events (should skip, not crash)
+
- [ ] Out-of-order event handling (already partially covered)
+
+
**Estimated Effort**: 4-5 hours
+
+
#### 7. Federation Readiness (Optional)
+
**What**: Test cross-PDS interactions
+
**Why**: Future-proofing for federation
+
+
- [ ] User on different PDS subscribing to Coves community
+
- [ ] User on different PDS commenting on Coves post
+
- [ ] User on different PDS voting on Coves content
+
- [ ] Handle resolution across PDSs
+
+
**Note**: Defer to Beta unless federation is alpha requirement
+

## Timeline Estimate
+
+
### Week 1: Critical Blockers (P0)
+
- **Days 1-2**: Authentication (JWT + did:web verification)
+
- **Day 3**: DPoP token architecture fix
+
- ~~**Day 4**: Handle resolution + comment count reconciliation~~ ✅ **COMPLETED**
+
- **Day 4-5**: Testing and bug fixes
+
+
**Total**: 15-20 hours (reduced from 20-25 due to completed items)
+
+
### Week 2: Production Infrastructure (P1)
+
- **Days 6-7**: Monitoring + structured logging
+
- **Day 8**: Database backups + load testing
+
- **Days 9-10**: Deployment runbook + final testing
+
+
**Total**: 30-35 hours
+
+
### Week 3: E2E Testing + Polish
+
- **Days 11-12**: Critical E2E tests (user journey, blob upload)
+
- **Day 13**: Additional E2E tests
+
- **Days 14-15**: Load testing, bug fixes, polish
+
+
**Total**: 20-25 hours
+
+
**Grand Total: 65-80 hours (approximately 2-3 weeks full-time)**
+
*(Reduced from original 70-85 hours estimate due to completed handle resolution and comment count reconciliation)*
+

## Go/No-Go Decision Points
+
+
### Can we launch without it?
+
+
| Feature | Alpha Requirement | Status | Rationale |
+
|---------|------------------|--------|-----------|
+
| JWT signature verification | ✅ YES | 🟡 Needs testing | Security critical |
+
| DPoP architecture fix | ✅ YES | 🔴 Not started | Subscriptions broken without it |
+
| ~~Handle resolution~~ | ~~✅ YES~~ | ✅ **COMPLETE** | Core UX requirement |
+
| ~~Comment count reconciliation~~ | ~~✅ YES~~ | ✅ **COMPLETE** | Data accuracy |
+
| Post read endpoints | ⚠️ MAYBE | 🔴 Not implemented | Can use feeds initially |
+
| Post update/delete | ❌ NO | 🔴 Not implemented | Can add post-launch |
+
| Moderation system | ❌ NO | 🔴 Not implemented | Deferred to Beta per PRD_GOVERNANCE |
+
| Full-text search | ❌ NO | 🔴 Not implemented | Browse works without it |
+
| Federation testing | ❌ NO | 🔴 Not implemented | Single-instance alpha |
+
| Mobile app | ⚠️ MAYBE | 🔴 Not implemented | Web-first acceptable |
+
+

+
+
## Risk Assessment
+
+
### High Risk
+
1. **JWT verification with production PDS** - Never tested with real JWKS
+
2. **Load under real traffic** - Current tests are single-user
+
3. **Operational knowledge** - No one has run this in production yet
+
+
### Medium Risk
+
1. **Database performance** - Queries optimized but not load tested
+
2. **Jetstream consumer lag** - May fall behind under high write volume
+
3. **Token refresh stability** - Community tokens refresh every 2 hours (tested but not long-running)
+
+
### Low Risk
+
1. **DPoP architecture fix** - Similar pattern already works (votes)
+
2. ~~**Handle resolution**~~ - ✅ Already implemented
+
3. ~~**Comment reconciliation**~~ - ✅ Already implemented
+
+

+
+
## Open Questions
+
+
1. **What's the target alpha user count?** (affects infrastructure sizing)
+
2. **What's the alpha duration?** (affects monitoring retention, backup retention)
+
3. **Is mobile app required for alpha?** (affects DPoP testing priority)
+
4. **What's the rollback strategy?** (database migrations may not be reversible)
+
5. **Who's on-call during alpha?** (affects runbook detail level)
+
6. **What's the acceptable downtime?** (affects HA requirements)
+
7. **Budget for infrastructure?** (affects monitoring/backup solutions)
+
+
---
+
+
## Next Steps
+
+
1. ✅ Create this PRD
+
2. ✅ Validate handle resolution (COMPLETE)
+
3. ✅ Validate comment count reconciliation (COMPLETE)
+
4. [ ] Review and prioritize with team
+
5. [ ] Test JWT verification with `pds.bretton.dev` (requires invite code or existing account)
+
6. [ ] Begin P0 blockers (DPoP fix first - highest user impact)
+
7. [ ] Set up monitoring infrastructure
+
8. [ ] Write critical E2E tests (especially full user journey)
+
9. [ ] Conduct load testing
+
10. [ ] Security review
+
11. [ ] Go/no-go decision
+
12. [ ] Launch! 🚀
