MoonBACnet is an independent MoonBit implementation of a bounded BACnet/IP object/property profile, licensed under Apache-2.0. It is not a line-by-line port of BACpypes3 or an implementation of every part of ASHRAE Standard135. No standard document text, usage databases or third-party fixture corpus is redistributed.

The interoperability vectors are constructed by the original `scripts/interop.py` test harness. Example device IDs, vendor999 and measurements are synthetic. They do not claim a real product, vendor assignment or observed deployment.

AI assisted topic comparison, design, source implementation, tests, debugging and documentation. Corrections were validated against typed independent vectors and negative tests. The project maintainer remains responsible for understanding the algorithms, actual deployment behavior, provenance and license compliance. Private application/review materials are excluded from version control and packages.
