Week 62: DDD Migration & Vendor Services — Dec 27, 2025 – Jan 2, 2026
TL;DR: Over 3,000 commits this week from the autonomous agent system. DDD migrations for Customer, Property, and Invoice entities. Vendor capacity tracking and COI compliance are live.
Highlights This Week
- DDD migration completed for Customer (25 methods), Property (2,495 LOC), and Invoice modules
- Built vendor capacity management with workload balancing
- Added Certificate of Insurance (COI) compliance automation
- Implemented MCP tenant context provider for property data
Domain-Driven Architecture
The DDD migration is the most significant architectural evolution since the platform’s inception. Each module gets: domain entities with value objects, repository interfaces, application services, DTOs with Zod validation, and PostgreSQL repository implementations. This layered architecture makes the codebase more testable, maintainable, and evolve-friendly.
How It Works
The DDD layered architecture follows strict dependency rules: Domain → no external dependencies; Application → depends on Domain; Infrastructure → implements Domain interfaces; API → depends on Application. The DI container wires everything together, and V2 API routes mount alongside legacy routes for gradual migration.
Under the Hood
- 3,043 commits from the agent system — peak autonomous output
- Vendor capacity: tracking active workload vs. maximum capacity per vendor
- COI compliance: automated expiry tracking with 30/60/90-day alerts
- E2E tests for 6 DDD API modules and Vendor COI endpoints
- MCP property-context provider for AI data access
What’s Next
Continued i18n polish, security hardening, and CLS performance fixes.
