Provenance

Portions of this software originate in the author's own earlier projects,
all under the same copyright and relicensed here under Apache-2.0:

  * MES-TWIN  - kernel domain model, OPC UA connectivity, OEE calculation,
                ERP adapters, authentication and audit trail
  * LineSim   - the deterministic line simulator used for CI and demos

This software depends on, but does not include, FactorySemantics (MIT),
the canonical manufacturing event model.

Everything in this repository derives from the sources above, from public
standards (ISA-95, ISA-88, PackML/ISA-TR88.00.02, ISO 22400, OPC UA), and
from public documentation. No part of it derives from any commercial MES
product's internals, schemas or documentation, and no employer data or
configuration is included.
