"""
orgstate.core — the pure analytical core of OrgState Engine.

This package is intentionally dependency-free (stdlib only) and I/O-free.
It contains the canonical data model and the deterministic signal/drift math.
Everything else (storage, API, connectors, verticals, delivery) builds on top.

Stage 0 migration: events, state, ontology, signals, drift, decisions were
moved here verbatim from legacy/orgstate_engine/ — they had zero cross-imports,
so no import rewrites were needed. See ../MIGRATION_MAP.md.
