# Code Review — TP-007 Step 4

Verdict: **APPROVE**

## Findings

No blocking findings. The Step 4 revision now uses the PRD-required `sleepQuality`/`sleepScore` labels, keeps computed scale metadata owned by the response shaper, removes stale caller-supplied `_meta.scales`, and leaves unregistered/custom fields unlabeled.
