Module event_source 

EventSource - registered event_kind → ComponentTag subscription table consulted by the engine’s Phase 3 bus event routing per ENGINE.md §10.7.

Syscall ops with event_subscriptions() declarations register themselves here at install time; the engine’s poll() Phase 3 consults subscribers(event_kind) to deliver each drained NodeEvent to the matching consumer ops.
