# Code Review Interview: section-06-script-ops

## Triage Summary

| # | Issue | Severity | Decision |
|---|-------|----------|----------|
| 1 | Path containment bypass via string prefix | HIGH | **Auto-fixed** — used `relative_to()` |
| 2 | PARTIAL status discards applied patches | Medium | **Let go** — plan-specified behavior |
| 3 | `_is_protected` misses normalized paths | Medium | **Auto-fixed** — use Path parts checking |
| 4 | `.godot` check too broad | Medium | **Auto-fixed** — tightened to parts-based check |
| 5 | PROTECTED_PATTERNS unused | Medium | **Auto-fixed** — removed dead code |
| 6 | `_op_create` ignores dry_run | Medium | **Asked user → Support dry_run** |
| 7 | Line count ambiguity | Low | **Let go** — implementation correct for real use |
| 8 | Regex misses @export var | Low | **Let go** — "basic" validation per spec |
| 9 | No test for unknown op | Low | **Auto-fixed** — added test |
| 10 | No direct _find_line_number test | Low | **Let go** — covered indirectly |
| 11 | auto_fix unused param | Low | **Let go** — documented as reserved |

## User Decisions

**Q: Should create mode support dry_run?**
A: Yes, support dry_run for create mode for API consistency.

## Auto-Fixes Applied

1. **Security fix**: Replaced `str.startswith()` containment check with `Path.relative_to()` — prevents bypass when project root is a prefix of another directory name
2. **Protected path check**: Rewrote `_is_protected` to use `Path.as_posix()` and split into parts for reliable matching
3. **Removed dead `PROTECTED_PATTERNS` constant** that was never referenced
4. **Added `dry_run` support to `_op_create`** with `DRY_RUN` status and `created: False`
5. **Added `test_create_dry_run_does_not_write` test** verifying create dry_run behavior
6. **Added `TestUnknownOp.test_unknown_op_returns_error` test** for unknown operation handling

## Final Test Count: 28 (26 planned + 2 added during review)
