# R008 Code Review — Step 1: Define histogram contract

**Verdict:** APPROVE

The R007 blockers are resolved. The contract now locks the pace stream formula and base units, and sport-setting selection has deterministic normalization, precedence, and tie-breaking rules. I did not find any remaining blocking contract gaps for Step 1.

## Non-blocking notes

- `STATUS.md:154-160` still has execution-log table rows appended under `## Notes` instead of the `## Execution Log` table. Move them when touching the file next so status parsing/rendering stays clean.
- `STATUS.md:96` lists R003 as `inline`, but `.reviews/R003-plan-step1.md` exists. Consider pointing the row at the file for consistency.
- For even tighter golden tests later, Step 2 can choose stable `unavailable.reason` values such as `missing_stream` and `insufficient_sample`; the current shape is sufficient for this contract step.

Tests were not run; this step only changes task/status documentation.
