- What challenges you encountered
- What diverged and why

## Generate Report

Save to: `.claude/execution-reports/[feature-name].md`

### Meta Information

- Plan file: [path to plan that guided this implementation]
- Files added: [list with paths]
- Files modified: [list with paths]
- Lines changed: +X -Y

### Validation Results

- Syntax & Linting: ✓/✗ [details if failed]
- Type Checking: ✓/✗ [details if failed]
