## Review Note: Missing Test Coverage
**Reviewer Oversight:** These tickets were passed with only MCP bridge tests verified (4 passed), not the full Rails test suite.
**Tickets affected:**
- #56 (Remove Artifact/CodeDiff) - Should verify no broken references to removed models
- #57 (assign/list tools) - Should add specs for new MCP controller handlers
- #58 (Simplify data model) - Should verify no broken references to removed models
**Required Actions:**
1. Run full test suite: `bundle exec rspec`
2. Add specs for new code:
- `spec/controllers/api/v1/mcp_controller_spec.rb` - test `list_members` and `assign_ticket` handlers
3. Verify no broken references to Artifact/CodeDiff models
4. Fix any failing tests related to removed systems
**Lesson:** Reviewer should require full `rspec` results for any ticket modifying Rails code, not just MCP bridge tests.
