Module events 

Pipeline events. Each time a new frame bundle is processed, the result decomposed by stage is emitted. This file is the shared contract of three modules (session, pipeline, sinks). Adding fields is allowed; changing or removing existing fields is forbidden.

Zone index and position range [lo, hi).

Enums
