"""autonomy — schema for a future per-minute LLM "deviate from plan" decision.

Defines AutonomyDecision (deviate / deviation_type / reason / duration)
as the structured contract for a behavior switch the brain may request.

Architecture: prepared for brain.py and the engine; currently no call
site exists (the decision is gated off until enabled).
Design: kept as a standalone schema so enabling autonomy later requires
no changes to existing callers.
