## Code Review
### Spec Pattern Search (REQUIRED)
- Searched for existing spec patterns: `find spec -name "*spec.rb" | sort`
- Found existing spec files:
- spec/features/ticket_workflow_spec.rb
- spec/features/ticket_comments_spec.rb
- spec/features/approvals_spec.rb, dashboard_spec.rb, kanban_board_spec.rb, etc.
- spec/requests/api/v1/tickets_spec.rb
- spec/models/ticket_spec.rb
- Similar patterns found: `ticket_workflow_spec.rb` and `ticket_comments_spec.rb` for ticket-related UI features
### Test Results
- Test suite run: `bundle exec rspec`
- Results: 714 examples, **2 failures**, 7 pending
**Note on Failures:** The 2 failing tests are in `spec/features/dashboard_spec.rb` and are caused by PR #111 (authentication) which is already merged. These failures are pre-existing and unrelated to this PR (#109).
### Spec Coverage Check
- Files changed:
- app/controllers/tickets_controller.rb (modified - added edit/update actions)
- app/views/tickets/edit.html.haml (new - 91 lines)
- app/views/tickets/show.html.haml (modified - added Edit button)
- config/routes.rb (modified - added edit/update routes)
- New specs added:
- spec/features/ticket_edit_spec.rb (new - 326 lines, 31 test scenarios)
- Test coverage for this PR: **COMPLETE**
- Visits edit page from show page
- Updates all fields (title, description, priority, type, PR URL)
- Parses dependencies from comma-separated input
- Parses working_memory from JSON with error handling
- Validates input (blank title, invalid JSON)
- Tests cancel functionality
- Tests partial updates (single field changes)
- Tests help text and UI elements
### Findings
- **Code quality:** Clean, well-structured Rails controller actions with proper strong params
- **Security:** JSON parsing with rescue for `JSON::ParserError`, dependencies parsed as integers, proper validation
- **Implementation:** Matches all ticket requirements - UI to update title, description, priority, PR URL, dependencies, working memory
- **Breaking changes:** None - this adds new functionality only
- **Input handling:**
- Dependencies: comma-separated string → array of integers with whitespace handling
- Working memory: JSON string → hash with proper error messages
- Validation errors displayed with daisyUI alert component
### Decision
**PASS - Excellent test coverage and implementation**
The PR adds comprehensive test coverage (326 lines, 31 scenarios) for the ticket edit functionality. All changes are isolated to ticket editing with no breaking changes. The 2 failing tests in the suite are pre-existing from PR #111 (authentication) which is already merged.
**Note:** The pre-existing dashboard test failures should be fixed separately by updating `spec/features/dashboard_spec.rb` to authenticate before accessing protected pages.
