Policy Engine 1.4.0

A deterministic, inspectable stage that maps signal snapshots to already allowlisted candidate intents.

Responsibility

evaluatePolicy(signals, { root }) is pure with respect to DOM writes. controller.runAuto() may evaluate and then submit candidates through the normal apply pipeline.

Pipeline position

Signals → Policy → candidate Intents. An optional local ranker may reorder those candidates before validation; it cannot add candidates.

Automatic mode

const controller = startAdapt(document, { auto: true });
controller.runAuto({ viewport: { width: 500, height: 800 } });

Constraints

Policy may	Policy must not
Use semantic roles and aggregate signals	Write DOM
Emit known intent types and values	Bypass scope, allowlists, or guardrails
Remain deterministic without AI	Require Local AI

Loop protection

Automatic resize collection is enabled only with auto: true. Mutations made by Semantic Apply do not re-enter policy.
