**Input**: Feature specification from `/specs/001-build-an-application/spec.md`
**Note**: This template is filled in by the `/speckit.plan` command. See `.specify/templates/commands/plan.md` for the execution workflow.
## Summary
Build a minimal web application using Flask that enables anonymous feedback submission with AI-powered analysis and translation. The system uses a file-based storage approach with folders for each submission, YAML metadata files, and markdown-formatted AI analysis reports. Product owners access analyzed feedback through an authenticated web dashboard. Design prioritizes simplicity and functionality over aesthetics - plain HTML without CSS frameworks or JavaScript libraries.
**POC Scope Update (2025-10-17)**: User Story 4 (Product/Service Registration and Management) has been **deferred** for the proof-of-concept. Products and users will be managed manually via YAML configuration files (`data/products/{id}/config.yaml` and `data/users.yaml`). This decision removes admin UI complexity while maintaining full functionality for POC validation. User Stories 1-3 (Anonymous Submission, AI Analysis, Dashboard) remain in scope and are **IMPLEMENTED**.
*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
### ✅ I. Specification-First Development
**Status**: PASS
Complete specification exists at `specs/001-build-an-application/spec.md` with prioritized user stories (P1-P4), 64 functional requirements with unique IDs (FR-001 to FR-064), measurable success criteria (SC-001 to SC-014), and comprehensive edge cases. All user stories are independently testable.
### ✅ II. Test-First Discipline
**Status**: PASS (Will be enforced during implementation)
Plan includes pytest as testing framework. Implementation phase will follow mandatory workflow: write tests → verify failures → implement code → refactor. Contract and integration tests prioritized per constitution.
### ✅ III. Independent User Stories
**Status**: PASS
Four user stories explicitly prioritized (P1: Anonymous Submission, P2: AI Analysis, P3: Dashboard, P4: Product Management). Each story is independently deliverable and testable. P1 can function standalone, P2 depends only on P1, P3 on P1+P2, P4 adds multi-product support.
### ✅ IV. Simplicity & Justification
**Status**: PASS
Design explicitly minimizes complexity: plain HTML without CSS frameworks, no JavaScript libraries, file-based storage (no database), Flask for web framework (minimal dependencies). User input emphasizes "designed as simple as possible" and "functionality over design."
**Potential Complexity Point**: File-based storage vs. database
- **Decision**: File-based storage with folder-per-feedback structure
- **Rationale**: Simpler deployment, no database setup/maintenance, natural fit for storing files+metadata together, sufficient for MVP scale (100 products × 10k items)
Specification-driven workflow with all documentation in version control under `/specs/001-build-an-application/`. This plan will generate: research.md, data-model.md, contracts/, quickstart.md per constitution requirements.
### Gate Result: ✅ PASS - Proceed to Phase 0 Research
No constitutional violations detected. Complexity Tracking table remains empty.

**Structure Decision**: Selected web application structure (Option 2 variant) with backend-focused layout since frontend is minimal (plain HTML templates). Flask follows a single-project structure but organized by layers (routes/services/models). The `data/` directory implements the file-based storage requirement with nested folders per product and feedback item. Templates directory contains plain HTML served by Flask without separate frontend build process.
## Complexity Tracking
*Fill ONLY if Constitution Check has violations that must be justified*
No violations detected. Table remains empty.
---
## Post-Design Constitution Re-Check
*Re-evaluated after Phase 1 design completion*
### ✅ I. Specification-First Development
**Status**: PASS (unchanged)
Design artifacts (research.md, data-model.md, contracts/, quickstart.md) generated from specification. No implementation code written yet.
### ✅ II. Test-First Discipline
**Status**: PASS (unchanged)
API contracts define testable behaviors. Contract tests can be written before implementation. Quickstart guide includes test-first workflow examples.
### ✅ III. Independent User Stories
**Status**: PASS (unchanged)
Data model and API contracts support independent implementation of P1→P2→P3→P4 stories. Each has clear endpoints and data structures.
