Verdict: COMMENT
Risk: LOW
Summary: The provider CSV changes are structurally clean: 14-column width is preserved, provider slugs remain unique and sorted, platform fields use repo-local identifiers rather than full URLs, and required validation is passing. I cannot approve this cycle because the current-cycle link-check report is not clean.
Findings: Current-cycle link-check run 32535290185 reported 1 URL error for https://nu.fi/ in references/providers/providers.csv with an HTTP/2 protocol error. Since approval requires a clean current-cycle link-check, please get a green link-check result before approval.
Confidence: HIGH
