Solutions

1. Register only through register_edge_processor
2. Inspect edge_processor_registry.get(name).load() to see the actual object type
3. Reinstall/align package versions so there is a single EdgeProcessorRegistration class

from runtime.edge.processors.registry import iter_edge_processor_registrations
assert 'myproc' in iter_edge_processor_registrations()

try:
    proc = build_edge_processor(cfg, ctx)
except RegistryError as e:
    logger.error('bad processor registration: %s', e)
    raise

When it happens

Trigger: Something wrote a non-EdgeProcessorRegistration object into edge_processor_registry under that name (bypassing register_edge_processor), and build_edge_processor/get_edge_processor_registration then loads it.

Common situations: Direct registry mutation by plugins, or version skew after upgrading the runtime where EdgeProcessorRegistration was redefined and isinstance checks fail across copies of the class.
