+# Tasks: Anonymous Feedback Platform (Reklamator)
+
+**Input**: Design documents from `/specs/001-build-an-application/`
+**Prerequisites**: plan.md, spec.md, research.md, data-model.md, contracts/
+
+**Tests**: Per constitution's Test-First Discipline (NON-NEGOTIABLE), tests MUST be written before implementation for each user story.
+
+**Organization**: Tasks are grouped by user story to enable independent implementation and testing of each story.
+
+## Format: `- [ ] [ID] [P?] [Story?] Description`
+- **[P]**: Can run in parallel (different files, no dependencies)
+- **[Story]**: Which user story this task belongs to (e.g., US1, US2, US3, US4)
+- Include exact file paths in descriptions
+
+## Path Conventions (from plan.md)
+- Project root: `reklamator/`
+- Application code: `app/`
+- Tests: `tests/`
+- Data storage: `data/`
+- Config: `config/`
+
+---

+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- **Setup (Phase 1)**: No dependencies - can start immediately
+- **Foundational (Phase 2)**: Depends on Setup completion - BLOCKS all user stories
+- **User Story 1 (Phase 3)**: Depends on Foundational (Phase 2) - MVP deliverable
+- **User Story 2 (Phase 4)**: Depends on Foundational (Phase 2) + User Story 1 (feedback must exist to analyze)
+- **User Story 3 (Phase 5)**: Depends on Foundational (Phase 2) + User Stories 1 & 2 (feedback and analysis must exist to view)
+- **User Story 4 (Phase 6)**: Depends on Foundational (Phase 2) - Can proceed in parallel with US1-3 if staffed
+- **Polish (Phase 7)**: Depends on all desired user stories being complete
+
+### User Story Dependencies
+
+- **User Story 1 (P1)**: INDEPENDENT - Can start after Foundational, no other story dependencies
+- **User Story 2 (P2)**: Depends on User Story 1 (must have feedback to analyze)
+- **User Story 3 (P3)**: Depends on User Stories 1 & 2 (must have analyzed feedback to display)
+- **User Story 4 (P4)**: INDEPENDENT - Can start after Foundational in parallel with others (admin features)
+
+### Within Each User Story
+
+- Tests MUST be written FIRST and verified to FAIL before implementation (constitution requirement)
+- Models before services (services depend on models)
+- Services before routes (routes depend on services)
+- Core implementation before integration
+- Story complete and tested before moving to next priority
+
+### Parallel Opportunities
+
+**Setup Phase (Phase 1)**:
+- Tasks T003-T009 can all run in parallel (different files)
+
+**Foundational Phase (Phase 2)**:
+- T011-T015, T017, T019, T021, T023-T024, T027-T029 can run in parallel (different files)
+
+**User Story 1 Tests**:
+- T030-T038 can run in parallel (all test different scenarios in same file but different test functions)
+
+**User Story 1 Models**:
+- T040-T041 can run in parallel (different model files)
+
+**User Story 2 Tests**:
+- T065-T069 can run in parallel (different test functions)
+
+**User Story 3 Tests**:
+- T093-T104 can run in parallel (different test functions)
+
+**User Story 4 Tests**:
+- T140-T152 can run in parallel (different test functions)
+
+**Polish Phase (Phase 7)**:
+- Most tasks T193-T210 can run in parallel (different concerns)
+
+**Team Parallelization**:
+- After Foundational (Phase 2), User Story 1 and User Story 4 can proceed in parallel (different domains)
+- Once US1 is complete, US2 can start while US4 continues
+
+---
+
+## Parallel Example: User Story 1 Tests
+
+```bash
+# Launch all contract tests for User Story 1 together:
+Task: "Contract test for GET /submit/{product_slug} in tests/contract/test_submission_routes.py"
+Task: "Contract test for POST /submit/{product_slug} with text only in tests/contract/test_submission_routes.py"
+Task: "Contract test for POST /submit/{product_slug} with files only in tests/contract/test_submission_routes.py"
+# ... all T030-T038 can be written in parallel
+
+# Launch both model creation tasks together:
+Task: "Create Product model in app/models/product.py with YAML loading"
+Task: "Create Feedback model in app/models/feedback.py with validation"
+```
+

+
+## Implementation Strategy
+
+### MVP First (User Story 1 Only)
+
+1. Complete Phase 1: Setup (T001-T009)
+2. Complete Phase 2: Foundational (T010-T029) - CRITICAL, blocks all stories
+3. Complete Phase 3: User Story 1 (T030-T064)
+   - Write tests FIRST (T030-T039)
+   - Verify tests FAIL
+   - Implement (T040-T064)
+   - Verify tests PASS
+4. **STOP and VALIDATE**: Test User Story 1 independently
+5. Can deploy/demo basic feedback submission at this point
+
+### Incremental Delivery
+
+1. Setup + Foundational (T001-T029) → Foundation ready
+2. Add User Story 1 (T030-T064) → Test independently → **MVP Deployment** 🎯
+3. Add User Story 2 (T065-T092) → Test independently → Deploy with AI analysis
+4. Add User Story 3 (T093-T139) → Test independently → Deploy with dashboard
+5. Add User Story 4 (T140-T192) → Test independently → Deploy multi-product support
+6. Polish (T193-T210) → Production-ready deployment
+
+Each story adds value without breaking previous stories.
+
+### Parallel Team Strategy
+
+With multiple developers after Foundational phase completes:
+
+**Option 1: Sequential (Safest)**
+- Complete US1 → US2 → US3 → US4 in order (dependencies respected)
+
+**Option 2: Parallel (If staffed)**
+- Developer A: User Story 1 (T030-T064)
+- Developer B: User Story 4 (T140-T192) - can work in parallel
+- Once US1 complete: Developer A starts US2
+- Once US2 complete: Developer A starts US3
+- Integrate and test all together

+
+## Summary Statistics
+
+- **Total Tasks**: 210
+- **User Story 1 (P1 - MVP)**: 35 tasks (T030-T064)
+- **User Story 2 (P2)**: 28 tasks (T065-T092)
+- **User Story 3 (P3)**: 47 tasks (T093-T139)
+- **User Story 4 (P4)**: 53 tasks (T140-T192)
+- **Setup + Foundational**: 29 tasks (T001-T029)
+- **Polish**: 18 tasks (T193-T210)
+
+**Parallel Opportunities**: ~80 tasks marked [P] can run in parallel with appropriate team structure
+
+**MVP Scope**: Phases 1-3 (T001-T064) = 64 tasks for basic feedback submission
+
+**Test Coverage**: 39 test tasks (constitution-mandated test-first approach)

+
+## Notes
+
+- [P] tasks = different files or independent test functions, no dependencies
+- [Story] label maps task to specific user story for traceability
+- Each user story designed to be independently completable and testable
+- **Constitution Requirement**: Tests MUST be written and verified to FAIL before implementing each story
+- Commit after each task or logical group
+- Stop at any checkpoint to validate story independently
+- Avoid: vague tasks, same-file conflicts, cross-story dependencies that break independence
+- File paths use plan.md structure (app/, tests/, data/, config/)
+- All security requirements (FR-055 to FR-064) integrated into relevant tasks
