Module event_bus 

Event bus: inter-agent communication via oxi_sdk::EventBus<KernelEvent>.

The event bus is the “pipe” of Oxios. All agents communicate through kernel events published on the bus.

After RFC-014 Phase C, this module no longer owns the broadcast channel — it reuses oxi_sdk::EventBus<E>, which is a generic wrapper over tokio::sync::broadcast. The only Oxios-specific bits are:

• KernelEvent enum (oxios-internal event vocabulary)
• kernel_event_to_audit_action mapping for the audit trail
• attach_audit_trail helper (subscribes the bus to the trail)

Enums

KernelEvent

Events that flow through the kernel event bus.

Functions

attach_audit_trail

Subscribe the audit trail to all kernel events.

kernel_event_to_audit_action

Convert a KernelEvent to an AuditAction for the audit trail.

Type Aliases

EventBus

Kernel event bus — generic SDK bus specialised for KernelEvent.
