+
+# Wait for services to initialize (3 minutes)
+sleep 180
+
+# Verify health
+docker-compose ps
+```
+
+**Effort:** 5 minutes
+**Owner:** DevOps/Infrastructure
+**Blocker:** Critical - must be done first
+
+### Short-term (E2E Testing - 30 min)
+1. Run: `bash tests/curl-test-collection.sh`
+2. Create test ticket in Freescout
+3. Monitor Workflow A (5 min)
+4. Verify Workflow B (2 min)
+5. Confirm Workflow C (1 min)
+6. Document results
+7. Update test report
+
+**Effort:** 30 minutes
+**Owner:** QA Team
+**Blocker:** Critical - validates functionality
+
+### Medium-term (Production Hardening - 1 day)
+1. Set up production TLS certificates
+2. Configure secret management
+3. Implement database backups
+4. Set up monitoring dashboards
+5. Create runbooks for common issues
+6. Train support team
+7. Dry-run disaster recovery
+
+**Effort:** 8 hours
+**Owner:** DevOps + Support Teams

+
+### Long-term (Ongoing Operations)
+1. Monitor performance metrics (24 hours)
+2. Handle user feedback
+3. Tune LiteLLM model parameters
+4. Optimize vector DB indexing
+5. Plan capacity expansion
+6. Update documentation with learnings
+
+**Effort:** Ongoing
+**Owner:** Operations Team
+**Blocker:** Post-launch responsibility
+
+---
+
+## Known Limitations & Mitigations
+
+### Limitation 1: Vector Database Size
+**Description:** Milvus configured for 1M embeddings
+**Impact:** After 1M solutions stored, performance degradation expected
+**Mitigation:** Archive old solutions, implement sharding strategy
+**Timeline:** Expected after 2 years of operation (assuming 1,300 solutions/day)
+
+### Limitation 2: LiteLLM Token Cost
+**Description:** Using GPT-3.5-turbo at ~$0.001 per 1K tokens
+**Impact:** $0.02-0.05 per ticket analysis (depending on ticket size)
+**Mitigation:** Implement token budget limits, use cheaper models for simple issues
+**Timeline:** Monitor costs after first 30 days
+
+### Limitation 3: Workflow Parallelization
+**Description:** n8n free tier limited to 5 concurrent workflows
+**Impact:** High-volume scenarios (>5 simultaneous tickets) will queue
+**Mitigation:** Upgrade to n8n Pro for unlimited parallelization
+**Timeline:** Evaluate after first month of operation
+
+### Limitation 4: Email Delivery Reliability
+**Description:** Email sending depends on Freescout's mail provider
+**Impact:** Email delivery may be delayed 5-30 minutes
+**Mitigation:** Implement retry logic in Workflow B, notify users of delays
+**Timeline:** Standard limitation of email infrastructure
+
+---
+
+## Risk Assessment & Mitigation
+
+### High Risk: Infrastructure Failure
+**Risk:** Docker containers crash
+**Impact:** System offline, tickets not processed
+**Mitigation:**
+- [ ] Implement container restart policies
+- [ ] Set up monitoring alerts
+- [ ] Create incident response runbook
+- [ ] Weekly health check automation
+
+### High Risk: Data Loss
+**Risk:** PostgreSQL or Milvus loses data
+**Impact:** Knowledge base lost, audit trail incomplete
+**Mitigation:**
+- [ ] Daily automated backups
+- [ ] Off-site backup storage
+- [ ] Recovery time objective (RTO): 1 hour
+- [ ] Recovery point objective (RPO): 1 day
+
+### Medium Risk: Performance Degradation
+**Risk:** Vector search becomes slow
+**Impact:** Workflow C takes >10 minutes
+**Mitigation:**
+- [ ] Monitor search latency
+- [ ] Implement caching strategy
+- [ ] Archive old vectors quarterly
+
+### Medium Risk: API Rate Limiting
+**Risk:** LiteLLM or Freescout API rate limits exceeded
+**Impact:** Workflow processing delays
+**Mitigation:**
+- [ ] Implement request queuing
+- [ ] Add retry with exponential backoff
+- [ ] Monitor API quota usage
+
+### Low Risk: Integration Breaking Changes
+**Risk:** Freescout API updates incompatibly
+**Impact:** Webhook receivers or API calls fail
+**Mitigation:**
+- [ ] Subscribe to API changelog
+- [ ] Implement API versioning
+- [ ] Quarterly integration testing
