OTA Updater
The OTA Updater is the only component allowed to change what software runs on the gateway. The cloud never pushes bits directly; instead it announces an update, and the updater pulls it, proves it is genuine, and applies it to a spare slot it can roll back to.
Beta: A/B rollback
The A/B slot strategy is currently rolling out across hardware revisions. Older single-slot gateways fall back to a verify-then-replace path without automatic rollback, so this component is marked beta until the fleet is fully on dual-slot images.
