metadata (30/60s) enforced 2026-07-21: worst legit per-IP rate observed in the preview window was 5/min, 6x under the threshold. calculate (75/60s) stays in preview — observed legit/partner clients run 39-88/min there, so enforcing would 429 real use including the partner's API fallback. Also documents that Armor throttle rules log only CONFORM in preview, so enforcement readiness must be judged from raw LB-log rate analysis. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
