OTA
Updating hosts and protocols without touching appliance firmware.
Overview
The YF1000 updates over the air. Protocols update independently of it, and appliances are updated least often of all.
Why the separation matters
Because care behaviour lives in protocols, improving care usually means shipping a protocol — not a firmware image to a certified device. That is the practical payoff of Principle 4, and it is what keeps the cost of iteration low.
