CHIEF.
The riding coach inside Sentinel. What it is, what it refuses to be, and what it actually sees.
CHIEF is an AI riding coach: it reads the data from a ride and tells you, in plain language, how it went and what to work on next.
It does not give real-time alerts, predict crashes, or make decisions for you — it tells you what it sees; the throttle is still yours.
It works in two layers — quick rules on your phone, deeper reasoning from Claude in the cloud — and when the signal drops it falls back to the on-device layer, so you are never left without feedback.
When CHIEF reaches the cloud it sends metrics, not your life: the numbers go up, your GPS track and your name do not.
