Distinct from relay failures (awaiting replay) and from quarantined frames (refused past the backout threshold and moved off the queue). Read-only: a refused message is never re-fed, and the alarm is closed on the alert surface. ## OpenAPI ````yaml /en/openapi/v3-current/siloc.yaml get /api/v1/siloc/dlq/deferred openapi: 3.1.0 info: description: >- OpenAPI 3.1 surface for Lerian SILOC, the participant-side rail connecting the institution to Núclea's SILOC deferred-net interbank settlement. title: Lerian SILOC API version: 1.0.0 servers: - url: https://siloc.sandbox.lerian.net security: [] paths: /api/v1/siloc/dlq/deferred: get: tags: - Connectivity summary: List parked deferred inbound messages description: >- A cursor-paginated feed of inbound messages parked for semantic replay (OT_DEFERRED and STATUS_DEFERRED), newest first, optionally narrowed to one lifecycle status. status=SEMANTIC_REJECTED lists the messages this rail terminally REFUSED on their content — parked with zero business effect, never replayed — which is what the INBOUND_SEMANTIC_REJECTED alarm points at.
