# Review R006 — Code Review for Step 2

**Verdict:** APPROVE

## Findings

No blocking findings.

The implementation adds the expected definition-drift guard coverage across the formula resource, shared analyzer fixture, `internal/analysis` computations, and representative `internal/tools` response surfaces. The guards pin formula refs, resource text hash/content, drift/decoupling boundary behavior, polarization states, z-score sample standard deviation behavior, EF resource-only status, and VI upstream-derived mapping/omission behavior.

## Verification

- `go test ./internal/analysis ./internal/resources ./internal/tools`
- `go test ./...`

Both passed.

## Notes

- The failure messages are sufficiently loud about definition drift and product review. If a future step wants a formal golden regeneration flow, consider adding an explicit update command/env var to the shared formula fixture tests, but I do not consider that blocking for this step.
