# Review R007 — Plan Review for Step 3

**Verdict:** APPROVE

## Findings

No blocking findings.

The Step 3 plan covers the required policy-documentation work: it adds an explicit note near the canonical formula/golden guard surface, checks contributor/tool-catalog documentation before changing it, and keeps the CHANGELOG scoped to user-visible behavior only.

## Notes

- `CONTRIBUTING.md` currently has schema stability guidance but no analyzer/formula drift guidance. During execution, prefer adding a short contributor-facing note there (for example near MCP tool conventions or tool schema snapshots) that formula ref/text/output changes are breaking/product-review events and require updating the associated golden guards deliberately.
- Avoid editing generated tool reference files unless tool descriptions/catalog metadata actually change.
- A CHANGELOG entry does not appear necessary if this step only documents contributor policy and does not change runtime/tool behavior.
