+- Include exact file paths in task titles
+
+## 2. Phase 1: Setup & Foundations (Prerequisites)
+- [ ] T001 Initialize database schemas and Prisma migrations
+- [ ] T002 Setup API routes and express middleware structures
+
+## 3. Phase 2: User Story 1 - Core Implementation (Priority: P1)
+- [ ] T003 [P] [US1] Create [Model] in src/models/[file].ts
+- [ ] T004 [US1] Build /api/v1/resource endpoint in src/routes/[file].ts
+
+## 4. Phase 3: Polish & Verification
+- [ ] T005 [P] Run linter and formatting checks
+- [ ] T006 Validate end-to-end user journeys
