# Code Review — Step 3

Verdict: **APPROVE**

## Findings

No blocking findings. The hydration semantics metadata is now only emitted for non-null fields, and the regression test covers the stale-null semantics case from R011.

## Verification

- Ran: `go test ./internal/tools -run 'TestGetActivityDetails|TestGetWellnessData'` — passed.
- Ran: `go test ./internal/tools` — passed.
