This is the cleanest\nkeyless-refusal shape observed in this lane's cluster, in contrast with LOINC's FHIR\nserver (silent SSO redirect, see sibling source `loinc-fhir-sso-gate`) and SNOMED's\npublic browser (multi-hop bot-defense redirect, see sibling source\n`snomed-snowstorm-public-browser-blocked`).
