Why: The approved extra sample ended with no valid saved findings and exhausted its per-run token threshold.
Evidence: Provider responses, strict-source rejections, Usage and independent analysis are retained; v7 has only local checks.
Impact: Define a separately approvable two-run 30000-token-per-run experiment without altering original acceptance rules or claiming model success.
