The câmara's own wire grids (LDL0024, LDL0023R1) are read at listScheduleGrids; nothing here computes a schedule. The recorded change appends an audit row, raises the single active SCHEDULE_CHANGE alert (deadline_at = effectiveAt), and emits a schedule.change-recorded fact — all atomically. windowSeq 3 records the LBTR close Núclea announces when it extends the grade on a day BACEN declares the STR down (OP002 §14.5): the movement day's LTR0002, LTR0008 and SLC0004 stay open until it instead of 17h30, and every other code of that day (requests, and queries by their NUOp day) stays open until it instead of midnight. A close recorded after 17h30 reopens nothing the 17h30 close already failed. ## OpenAPI ````yaml /pt/openapi/v3-current/siloc.yaml post /api/v1/siloc/schedule/changes 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://api.example.com description: >- Replace the example host with the URL provided during environment onboarding. security: [] paths: /api/v1/siloc/schedule/changes: post: tags: - Schedule summary: Record a contingency schedule change description: >- Records an out-of-band-received Núclea schedule announcement (OP002 §14 = telephone/e-mail) as an operator-entered operational fact, projected verbatim.
