OTA Service
The OTA Service turns “ship firmware v1.8.2 to the EU fleet” into a safe,
observable, staged rollout. It owns the campaign definition, decides which
devices get the update when, and tracks the result device-by-device.
Safety first
Firmware rollouts are the highest-risk fleet operation. The service always rolls out in staged cohorts with health gates between stages, so a bad build is caught on a small percentage before it can reach the whole fleet.
