Clients stop an orcad that advertises health.stopRequests through its slot-local request file and keep SIGTERM for older builds. Decommission runs through the activation journal and fence: it refuses while the terminal census is live or uncounted, stops the instance with an instance-bound managed request, cancels a stop orcad never acted on, and deactivates the record only on proven exit. orcad gains --cancel-managed-stop and an exclusive per-transaction decision file so a cancel can never race a dispatched stop. POSIX-only and inert: no production caller.
