Module stream 

Transport-neutral runtime stream primitives.

This module defines the envelope, routing key, and stream type used by the runtime stream abstraction. The design is inspired by the Socket.IO Adapter rules (room-based fanout, per-room ordering, best-effort live delivery), but it is not a Socket.IO implementation and carries no transport coupling.

• RuntimeStreamAdapter performs best-effort live fanout only.
• RuntimeEventStore is the authoritative replay source.
• Delivery is at-least-once; consumers deduplicate via RuntimeEventId or RuntimeEventEnvelope::seq.
• Authorization is not modeled here; rooms express fanout routing only and must be gated by the transport/service layer before subscription.

Structs

RuntimeEventEnvelope

Envelope wrapping an AgentEvent with cross-instance routing metadata.

RuntimeEventId

Globally unique identifier for a single runtime event.

Enums

RuntimeRoom

Fanout routing key, inspired by a Socket.IO room but transport-neutral.

RuntimeStreamError

Errors raised by a RuntimeStreamAdapter.

Type Aliases

BoxRuntimeEventStream

Owned, type-erased stream of runtime event envelopes.
