Read-only: Lerian SILOC values no asset, computes no exposure and originates no deposit; acting on an advisory is a command an operator or the ledger consumer sends. Each arriving advisory also raises its operator alarm (COLLATERAL_REQUIRED, COLLATERAL_SUBSTITUTION, ELIGIBLE_ASSETS_CHANGED) on listAlerts and never affects readiness. ## OpenAPI ````yaml /en/openapi/v3-current/siloc.yaml get /api/v1/siloc/collateral/advisories 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/collateral/advisories: get: tags: - Collateral summary: List câmara collateral advisories description: >- The collateral advisories the câmara sent — LDL1001 (exigibilidade de colateral), LDL1011 (ativos a serem substituídos) and LDL1014 (alteração na lista de ativos elegíveis) — keyset-paged newest announced first, each projected verbatim including the amounts, deadlines and asset identifiers the câmara carried.
