# Code Review — TP-007 Step 5

Verdict: **APPROVE**

## Findings

No blocking findings.

The revision addresses the previously noted Step 5 issues:

- Row-collection item metadata now drops caller-supplied `_meta.units` before returning shaped rows, so unit metadata remains response-owned.
- `get_athlete_profile` now uses a single `profileUnitSystem` source for both the visible `units.measurement_preference` value and `response.Options.UnitSystem`, including the explicit metric fallback when profile unit fields are absent or unknown.

## Validation run

- `git diff 22dda51..HEAD --name-only` — inspected changed files.
- `git diff 22dda51..HEAD` — reviewed full diff.
- `go test ./...` — passed.
