# Review R008 — Code Review for Step 3

**Verdict:** APPROVE

## Findings

No blocking findings.

The Step 3 changes document the formula-drift policy in both places requested: a concise note near the canonical formula entries and contributor-facing guidance in `CONTRIBUTING.md`. The policy correctly treats formula refs/text and pinned analyzer outputs as public contracts that require explicit product approval and golden fixture updates. The decision not to update `CHANGELOG.md` is reasonable because this step changes contributor policy only, not runtime or user-visible behavior.

## Tests

Not run; changes are documentation/note-only for this step.
