# Review by Andrej Karpathy (Round 3)

## Review Complete

Here's my assessment as Andrej Karpathy:

**VERDICT: approve**

**Key findings:**

1. **naming.py is well-designed** — `ReviewArtifactPath` frozen dataclass + 5 deterministic factory functions. Timestamp injection for testability is the right pattern.

2. **Path traversal defense-in-depth is solid** — Double guard in `_save_review_artifact()` validates both subdirectory and final filename, protecting against malicious agent-generated persona slugs.

3. **Test coverage is thorough** — 245 tests pass. New tests cover all factory functions, immutability, sanitization, path traversal rejection, subdirectory creation, and `.gitkeep` files.

4. **Minor: `task_review_artifact_path` is defined but unwired** — FR-9 factory function exists and is tested in `naming.py`, but `orchestrator.py` doesn't import or call it. Forward-looking infrastructure that's acceptable but worth noting.

5. **Minor prompt engineering concern** — Instruction templates describe the directory structure in natural language rather than providing explicit glob patterns. LLMs work more reliably with concrete paths like `{reviews_dir}/reviews/**/*.md` than "each persona has its own subfolder."
