Docker-based Sparkplug B 3.0 interoperability testbed with 6 reference stacks, 4 MQTT brokers, deterministic fixtures and automated cross-stack tests.

Sparkplug B host application in Python that gets the awkward parts right: bdSeq correlation, sequence gaps treated as reordering, rate-limited rebirth, a dependency-free codec. 14 scenarios, no broker, about 1 s.

Yggdrasil northbound FEEDER — consumes a governed equipment definition, provenance-verifies it, and streams live OPC-UA instance data to a Sparkplug B / MQTT UNS (NBIRTH carries the governed def byte-exact; egress-validated NDATA). Zero shared code with Bifrost.
