The unified agent gains an availability module: probe assignments arrive through the signed remote-config channel (missing key clears the schedule), each enabled target runs on its own clamped interval through the shared probe core, and results queue in a bounded drop-oldest buffer. A result is offered to the primary server until one delivery succeeds and never again after - buffered offline reports are stripped of availability results so the disk buffer cannot replay observations the queue still holds. ApplyHostReport feeds accepted reports into the probe ingestion path, where the ownership check and failure accounting live, and the probe agent id is projected onto unified availability resources for source attribution in the UI.
