This is the review step in a Git-based workflow system that evaluates your implementation branch against the original plan. It runs git diffs, checks your work against acceptance criteria, and forces you to categorize findings into "Fix Now," "Needs Spec," or "Create Issues" before making an accept or rework call. The discipline here is good: it appends review notes to your task body and captures lessons for the next planning cycle. You'd run this after finishing implementation work but before merging. The constraint that 80% of the compound loop's value lives in planning and review tells you exactly how the author thinks about iteration quality.
