Get a participant's operational status
Returns the latest PAG0101 operational status recorded for the participant, plus nonOperating — whether the submission gate blocks it, computed with the SAME predicate the gate uses. A participant with no notice yet answers 200 with status NO_NOTICE and nonOperating false (the gate’s own rule: no notice does not block), NOT a 404; a participant absent from the tenant’s catalog is a 404. RBAC: participants:read; tenant is always derived from the validated request identity.
Response
OK
What the PREVIOUS row for this ISPB carried — a REWRITE marker, not a transition. PAG0101 is a recurring full-roster snapshot (at least 2 per business day) and there is no insert-only-on-change guard, so for a stable institution this equals status on essentially every read; a differing value is the exception. Diagnostic only: the submission gate reads status. Null on a first-ever notice or a NO_NOTICE answer.
ACTIVE, SUSPENDED, SPECIAL_REGIME, null "ACTIVE"
