gurixandClaude 0f71ba969f Add implementation plan for product selection landing page (Feature 002)

Completed planning phases 0 and 1 for simple landing page feature.

## Plan Overview:

**Approach**: Minimal addition to existing Flask app - reuse Product model,
add one route, one template. No new dependencies or complexity.

**Constitution Check**: ✅ All 5 principles satisfied
- Specification-first development (spec.md complete)
- Test-first discipline (TDD workflow defined)
- Independent user stories (3 stories, all independently testable)
- Simplicity (reuses existing Flask/Jinja2/Product architecture)
- Documentation as code (all artifacts in specs/002-product-list/)

## Artifacts Created:

### Phase 0: Research (research.md)
- Reuses infrastructure from feature 001 (Flask, Jinja2, file storage)
- Single new decision: Product.load_active() method for filtering/sorting
- Performance analysis: <100ms for 100 products (well under 1s target)

### Phase 1: Design & Contracts
- **data-model.md**: Documents Product model extension (load_active method)
- **contracts/landing-page.yaml**: OpenAPI contract for GET / route
- **quickstart.md**: Developer implementation guide with:
  - Step-by-step implementation checklist
  - Code snippets for route, template, tests
  - TDD workflow (write tests → verify fail → implement → pass)
  - Manual verification checklist

### Agent Context
- Updated CLAUDE.md with feature technologies (no new tech added)

## Implementation Summary:

**New Files** (to be created):
- app/routes/landing.py - Landing page route handler
- app/templates/landing/index.html - Product list template
- tests/contract/test_landing_routes.py - Contract tests (6 scenarios)
- tests/integration/test_landing_flow.py - User journey test

**Modified Files**:
- app/models/product.py - Add load_active() class method
- app/__init__.py - Register landing blueprint

## Key Technical Decisions:

1. **Filtering**: status=='active' AND submission_url_slug exists
2. **Sorting**: Alphabetical by name (case-insensitive), then product_id
3. **Empty State**: "No products are currently accepting feedback" message
4. **XSS Prevention**: Jinja2 auto-escaping (no manual escaping needed)
5. **Performance**: File I/O sufficient (<1s for 100 products, no caching)

## Next Steps:

1. Run /speckit.tasks to generate tasks.md
2. Run /speckit.implement to execute TDD workflow
3. Verify all tests pass
4. Manual verification checklist
5. Create pull request
