# CAI Score API

> The Cognitive Autonomy Index as an HTTP API — send five behavioural answers plus a role roster to `POST /v1/score` and receive a score, a zone, and rule-based suggestions per role.

The score is `(L_c × S × 0.2) / L_t`. The three parameters — `L_c`, `S`, and `L_t` — are derived from the five behavioural answers rather than sent by the caller. `L_t` is the strictest of three ceilings: regulation, reversibility, and detection. The result falls into one of three zones: `stranded` below 0.92, `right` from 0.92 to 1.08, and `risk` above 1.08.
