Cross-plane sentinel pattern: a tiny watcher on cloud plane B detects the SILENT death of scheduler plane A (billing block, cron load-shedding; zero error signal from inside) and alerts the operator by email. Fail-open: the canary's own failure never harms the host work. Includes the fine-grained-PAT 403 gotcha, the no-echo secret intake protocol, and the MANDATORY live test (a canary never test-fired protects nothing). Load when schedulers die silently, when 'nothing ran and nothing alerted', when building any watchdog/canary, or when activating one that has never fired.
