A RECALCULATION alert carries its correlated cycle's active recálculo round complement window, read verbatim from ot_recalculations — never netted, summed, or recomputed (D-4). A connection-level alert (e.g. RELAY_DOWN) carries no cycle and no window. activeOnly=false includes deactivated alerts (history). Read-only — cross-operator acknowledgement is handled by br-desk, not this rail. ## OpenAPI ````yaml es/openapi/v3-current/siloc.yaml get /api/v1/siloc/alerts 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.
