Crate af_agent_session

Expand description

Event-sourced Agent sessions. The append-only log is the conversation SSOT; messages, runs, interactions and UI state are deterministic projections.

Structs§

OpenToolCall: A tool call awaiting its result.
ProjectedContext: Injected context as projected for UI and replay.
ProjectedMessage: Message as projected for UI and replay.
RecordedToolCall: A tool call as recorded in AssistantToolCalls.
SessionEvent: One committed Session event with its position in the log.
SessionProjection: Deterministic projection of a Session log used by the runtime, recovery and UI.

ContentBlock: Typed content unit; UI and models parse types, never prose conventions.
DeliveryMode: How queued input reaches a Run.
Event: Every model-visible fact and lifecycle transition of a Session. The log is the source of truth; everything else is a projection.
EventError: Invariant violated while applying an event.
InteractionKind: What the Run asks the user for.
InteractionResolution: How the user resolved an interaction.
RunState: Projected lifecycle state of one Run: live, parked on an interaction, or terminal.
RunStatus: Terminal Run status.
ToolAuthorizationStatus: Authorization outcome of a tool call.

SESSION_EVENT_FORMAT_VERSION: Wire/storage format of Event; only structural changes bump it.

cancel_events: Events that close an interrupted Run as cancelled.
failure_events: Events that close an interrupted Run as failed with error_code.
recovery_events: Events that close an interrupted Run as failed with worker_restarted, so recovery starts from a clean lifecycle.
session_deletion_events: Events that tombstone a Session and close its Runs.
text: One text content block.
