# Code Review: Step 1 — Design diagnostic contract

Verdict: **APPROVED**

No production code was changed in this step. The only changes are the approved plan review artifact and STATUS updates capturing the diagnostic contract. The contract now includes a visible comparable catalog fingerprint, neutral mismatch semantics, privacy boundaries, and a same-version drift test plan.

Non-blocking note: the two review execution-log rows currently appear under `## Notes` rather than in the `## Execution Log` table; clean this up when updating STATUS for the next step if Taskplane parsing depends on that table.
