+
+## 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
+
+## Current Parent
+- Conversation ID: f0dc21e1-9715-45da-a5b2-12e1b082fdff
+- Updated: 2026-06-28T23:47:00Z
+
+## 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/progress.md` — Progress log
+- `/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

+## Loaded Skills
