Longitudinal compliance layer

A deterministic go / hold verdict — with evidence — at every care gate.

Precursor checks the process and policy prerequisites a patient must meet before each step of care — the first wedge is surgical readiness. It is not a shared care record and it never diagnoses: a rules engine returns the verdict, AI is assistive and removable, and every answer traces to its evidence.

The engine decides

The go/hold verdict is a pure, deterministic function of facts + rulepack — never an AI guess.

AI is removable

Models are assistive input only. Turn AI off and every verdict is identical — a blocking CI gate.

Everything traces

Verdict → pack version → evidence pointer → canonical resource. A pointer, never a copied clinical value.

Human sign-off always

GOOD_TO_GO is always pending an attributed clinician sign-off. No silent green.
