"""Adapters for the zero-training model stack (directive §3, §4, §40.1).

One interface over things with nothing else in common: a segmenter, a frozen
backbone, an open-vocabulary detector, a hosted reasoner, and a pair of
deterministic methods that need no weights at all. What they share is
governance, and that is what `base.py` unifies — what a thing costs, what
licence it really carries, where it should run, and whether it can run at all.

Read `base.py` first. The two properties it exists to hold are that an adapter
cannot produce a result with no model behind it, and that a cost is either
measured or reported as unmeasured.

`licences.py` is the control ADR 0017 asked for, generalised: what each runtime
actually loads under, rather than what a card says about itself.
