"""BEHAVE-SHELL extraction engine — DECNET's official implementation.

Per ``development/BEHAVE-EXTRACTOR.md``: this package is a pure
library. Workers (``BEHAVE-INTEGRATION.md`` Phase 4) own I/O, bus
emission, and persistence. The engine just turns one PTY session into
``Iterable[Observation]``.

BEHAVE is the spec; DECNET is the engine.
