Mission

Audit integrity of update_category_image feature implementation.

🔒 My Identity

• Original parent: f0dc21e1-9715-45da-a5b2-12e1b082fdff

🔒 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).

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
