## Mission
Audit integrity of update_category_image feature implementation.

## 🔒 My Identity
- Archetype: forensic_auditor
- Roles: critic, specialist, auditor
- Working directory: /home/ti/git/homaroma/.agents/teamwork_preview_auditor_m1_2
- Original parent: f0dc21e1-9715-45da-a5b2-12e1b082fdff
- Target: update_category_image feature implementation

## 🔒 Key Constraints
- Audit-only — do NOT modify implementation code
- Trust NOTHING — verify everything independently

## Audit Scope
- **Work product**: Category image update (endpoint `PATCH /api/categories/:id/image`, MCP tool `update_category_image`)
- **Profile loaded**: General Project
- **Audit type**: forensic integrity check

## Audit Progress
- **Phase**: reporting
- **Checks completed**:
  - Source Code Analysis (Elysia routes, Prisma client integration, MCP schemas & handlers)
  - Behavioral Verification (Workspace build, typescript validation, integration tests execution)
  - Schema & Error Handling Verification (Elysia schema validation for type correctness, DB row existence verification)
  - Database Persistence Verification (Verified database update propagates to PostgreSQL Category table)
- **Checks remaining**: None
- **Findings so far**: CLEAN

## Key Decisions Made
- Executed integration tests for backend router (`test_category_image.ts`) and MCP server (`test_mcp_category_image.ts`).
- Inspected PostgreSQL database to verify actual persistence.
- Verified Elysia validation schemas and HTTP status codes (200, 404, 422).

- `/home/ti/git/homaroma/.agents/teamwork_preview_auditor_m1_2/handoff.md` — Final audit findings report

## Attack Surface
- **Hypotheses tested**:
  - Invalid types rejected by API -> Checked: PATCH returns 422 when imageUrl is not a string/null.
  - Non-existent category fails gracefully -> Checked: PATCH returns 404 with exact database error code mapped.
  - Actual database persistence -> Checked: Category 1 imageUrl updated to "https://example.com/mcp-test.png" in postgres.
- **Vulnerabilities found**: None
- **Untested angles**: None
