Dependencies Identified

Hard Dependencies (Must Complete Week 1)

1. ✓ warranty_tracking table migration
2. ✓ webhooks table migration
3. ✓ Event Bus service (event-bus.service.js)
4. ✓ Webhook delivery service (webhook.service.js)

Mitigation:

• Fallback to email notifications if HA unreachable
• Optional stretch goals can be deferred
• Contingency tasks defined for Day 5

4. Nov 24: Defer MQTT/camera unless team ahead of schedule
5. Daily: Track token usage and performance metrics
