Module participant 

Server-owned participant storage and transport bindings.

The conversation event stream, opaque aggregate owner, and connection- incarnation stream are production durability boundaries over protocol-owned transitions. The older crash/cursor/detach repositories remain test-only regression fixtures until their operations move behind the aggregate.

Modules

dispatch_impact

Typed post-commit tells for participant obligation dispatch.

Structs

ConnectionFateWorkItem

One durable bounded connection-fate intent delivered to participant semantics.

InstalledParticipantService

Server-sealed participant activation token installed on a connection supervisor.

MarkerSourceRefused

Refused association retaining the move-only owner/recovery pair.

ObserverPublicationTarget

Weak exact-live-connection target captured when an observer arm is installed.

ParticipantConnectionContext

Connection-scoped authority facts supplied to participant semantics.

ParticipantConnectionConversations

Connection-local semantic-conversation dispatch map (contract R-D1: the connection’s binding/interest/dispatch maps are bounded by the signed max_semantic_conversations_per_connection).

ParticipantConnectionFateOutcome

One connection-fate result paired with every conversation impact committed before the fate operation returned.

ParticipantOfferedProgress

Connection-local volatile offer cursor for one conversation and exact binding. A different binding epoch discards this progress and restarts from the durable recipient acknowledgement frontier.

ParticipantPublication

One exact durable obligation selected for the connection’s current binding.

ParticipantSemanticOutcome

One semantic result paired with every dispatch effect durably installed by the request before it returned.

ParticipantSession

Participant capability negotiated on one authenticated connection.

ValidatedFencedMarkerInputs

Source-associated inputs which still contain no one-use marker token.

Enums

ConnectionFateClass

Exact terminal classification preserved from a connection’s close trigger.

MarkerSourceRefusalReason

Typed reason an exact marker source cannot authorize later mint inputs.

ParticipantDispatch

Result of dispatching one generic frame through participant transport.

ParticipantDispatchError

Failure after a generic frame has entered participant dispatch.

ParticipantIngress

Result of classifying one preserved generic frame through the shared gate.

ParticipantSemanticError

Non-wire semantic service failure.

ParticipantServiceFatal

Process-wide terminal participant-service latch.

Constants

PARTICIPANT_CAPABILITY_BIT

Reserved connection-capability bit for participant-v1.

Traits

ParticipantSemanticHandler

Server-owned adapter from a decoded request to a protocol-owned value.

Functions

dispatch_generic_frame

Gates, decodes, semantically applies, and encodes one participant frame.

encode_server_push

Encodes one crate-produced server push into the participant generic frame on the protocol-owned generic stream zero.

encode_server_value

Encodes one crate-produced semantic value into the existing generic frame.

gate_generic_frame

Applies the shared participant gate to one generic frame preserved by liminal’s forward-compatible decoder.

normalize_configured_frame_limit

Normalizes the operator’s raw configured WF to the generic frame ceiling.

preflight_generic_bytes

Rejects an oversized participant frame from its generic header before the connection buffers the declared body.

validate_marker_source

Point-reads and validates one durable marker source before the retained owner may proceed to its private one-use authority mint.
