The API does not run a runtime LLM, does not log raw questions, and does not generate open-ended claims. Empty questions return HOLD / RC_EMPTY_QUESTION, unknown questions return HOLD / RC_NO_PUBLIC_ANSWER_CARD, incomplete RELEASE cards fail closed to HOLD, and ESCALATE cards remain ESCALATE for human review. The answer_status field is an alias of status. The reason_codes field is an array alias whose first element is reason_code."
