# R010 code review — Step 4: Reference-server measurement

Verdict: **APPROVE**

## Findings

No blocking findings. The prior Step 4 issues appear addressed: reference artifacts are in `HEAD`, unavailable calls are explicit `isError=true` rows, athlete IDs are redacted from measurement environments, audited raw response bytes are used instead of padding, and `.5` medians are preserved.
