How to read this

The engine sees only the live stream — never the hidden fault. It keeps a probability over root causes, then asks for the single most informative test (value of information) and updates. It only marks a call underwritable when fully tested and ≥85% confident, and will say “inspect” rather than guess.

Live calibration — real data

No labeled cases yet.
Every confirmed fix you log feeds this. When the engine says N%, this checks it's right about N% of the time (ECE). This is the moat — it gets more honest with every car.

Evidence trace

Readings the engine has weighed appear here.
Demo runs on a physics-plausible simulator (no hardware). Signatures are grounded in real OBD diagnosis; a real OBD dongle plugs into the same ingestion interface. See docs/CONCEPT.md.
