Filterable by occurred_at range (from/to, inclusive), action type, and participant ISPB. Every field is a stored column projected verbatim — no counts, no aggregates, no derived durations (D-4). Read-only: the trail is never mutated through this surface. ## OpenAPI ````yaml es/openapi/v3-current/siloc.yaml get /api/v1/siloc/audit-records openapi: 3.1.0 info: description: >- Interfaz OpenAPI 3.1 de Lerian SILOC, el riel del lado del participante que conecta la institución con la liquidación interbancaria diferida por neteo SILOC de Núclea.
