```
**Key Dependencies:**
- US1 (Auth) blocks US2 (Boards) - need auth before creating boards
- US2 (Boards) blocks US3 (Upload) - need boards to upload images to
- US3 (Upload) blocks US4-US18 - need images before manipulating them
- US4 (Navigation) + US5 (Positioning) run in parallel
- US6-US18 are mostly independent (can parallelize)
---
## Parallel Execution Examples
### Week 1 (Setup) - 13 Parallel Tasks
```bash
# All [P] tasks in Phase 1 can run simultaneously
T002, T003, T004, T006, T008, T010, T011, T012, T013, T014, T016, T019
```
### Week 2 (Auth) - Backend & Frontend in Parallel
```bash
# Backend team:
T036, T037, T045, T046, T047 # Models, schemas, tests
# Frontend team:
T048, T049, T053, T054, T055 # Pages, components, tests
# Both teams work simultaneously on US1
```
### Week 5-6 (Canvas Foundation) - Full Parallel
```bash
# Canvas controls (US4):
T101, T102, T103 # Pan, zoom, rotate all independent
# Position & selection (US5):
T111, T112, T113 # Can work on different aspects
# Tests:
T109, T118, T119, T131 # All test writing can be parallel
```

## Implementation Strategy
### MVP Scope (Minimum Viable Product)
**Critical Path (Must-Have for Beta):**
- Phase 1-2: Setup & Foundation
- Phase 3: US1 (Auth)
- Phase 4: US2 (Boards)
- Phase 5: US3 (Upload)
- Phase 6-7: US4-US5 (Canvas basics)
- Phase 8: US6 (Transformations)
**Total for MVP: ~120 tasks (Weeks 1-8)**
This gives you a functional app where users can:
- Register and login
- Create boards
- Upload images
- Arrange images on canvas
- Apply basic transformations
### Full Feature Set (v1.0 Release)
Add remaining phases 9-25 for complete feature set per specification.
**Total: All 331 tasks (Weeks 1-16)**
### Incremental Delivery
Each user story phase is independently testable:
1. Complete phase (all tasks done)
2. Run phase tests (verify acceptance criteria)
3. Deploy to staging
4. Get user feedback
5. Move to next phase
This allows for continuous delivery and early user validation.

## Notes
### Parallel Development Opportunities
**Week 1:** 13 setup tasks can run in parallel
**Week 2:** Backend + Frontend teams work independently on US1
**Week 3-4:** Backend + Frontend can work on different user stories
**Week 5-12:** Each user story is independent - can parallelize across team
**Week 13-16:** Most polish/deployment tasks are parallelizable
### Test Coverage Strategy
- Unit tests written alongside implementation (same phase)
- Integration tests after unit tests pass
- E2E tests in Phase 23 (Week 15)
- Coverage tracked continuously in CI
- 80% threshold enforced before merge
### Code Review Process
- All tasks require code review before marking complete
- Constitution checklist verified during review
- Performance impact assessed for canvas/API changes
- Security review for auth/sharing features
