# Review by Andrej Karpathy (Round 1)

## Review Summary

**VERDICT: request-changes**

The implementation is dead on arrival. Here's what I found:

1. **Zero commits on the branch** — HEAD and main point to the same commit. Nothing was shipped.

2. **Unresolved merge conflicts** — `config.py` and `models.py` contain `<<<<<<< HEAD` markers that cause `SyntaxError`, making the entire test suite unrunnable.

3. **Core feature missing** — The sequential task runner (FR-3 through FR-7) — which is the entire point of this PRD — was never implemented. The orchestrator still uses the old single-prompt fallback that dumps all tasks into one agent session.

4. **Only Task 1.0 partially done** — The config default flip from `True` to `False` and the warning log are present in the working tree but trapped behind conflict markers.

**The irony**: This PRD exists because parallel implementation causes merge conflicts. The implementation itself was derailed by... merge conflicts from the agent trying to work in parallel. This is the strongest possible argument for why this feature needs to be built — and it needs to be built *sequentially*.
