# Code Review — Step 2

Verdict: **APPROVE**

No blocking findings.

Notes:

- Added regression coverage proves extended-metrics raw joule fields are divided to kJ for activity (`icu_joules_above_ftp`, `ss_w_prime`) and interval (`wbal_start`, `wbal_end`, `joules_above_ftp`) outputs.
- `_meta.extended_metric_units` is asserted for the kJ-labeled fields, including `w_prime_balance_end_kj`.
- Preferred-unit response tests now lock KJ/KCAL pass-through and preservation of unknown raw unit labels.
- Step 2 audit discoveries in `STATUS.md` match the current public surfaces reviewed.

Verification run:

- `go test ./internal/response ./internal/tools`
