Skip to main content Module runtime Copy item path Source AgentFrameRun Result of driving one logical host turn through any AgentFrame switches. AssembledTurn Canonical high-level turn result returned to hosts. AssistantOutput Canonical assistant output payload. CodeOutputRecord RLM code execution output observed during a turn. DefaultProcessCancelAbility DirectCompletionClient DurableProcessWorker Reconstructable background-process worker. DurableProcessWorkerConfig Deployment-local configuration for rebuilding durable process executions. EmbeddedRuntimeBuilder EmbeddedRuntimeHost Base host shape for embedded runtimes. ExecutionSummary High-level execution summary for a completed turn. InMemorySessionStore InMemorySessionStoreFactory Session-id-keyed factory: the same in-memory store is returned for a given
session across opens (so a worker rebuild sees the session’s state), and a
fresh store is created on first use. Inline durability tier. InlineEffectHost In-process deployment effect host. InlineProcessRunHandle Inline run handle: drives the worker’s own lease-protected sweep in-process. InlineRuntimeEffectController Default in-process effect controller. LashRuntime Generic runtime for CLI or programmatic embedding. LiveTurnInputs Per-turn, in-process side channel of typed plugin inputs. LlmAttachmentSpec Serializable attachment data for runtime effect envelopes. LlmRequestSpec Serializable LLM request data. Live stream and provider-trace callbacks are
attached by the local executor, and attachment bytes are resolved locally
from refs rather than persisted in the effect envelope. NoopEventSink No-op sink useful for callers that only care about final state. NoopTurnActivitySink ObservedProcess ObservedProcessEvent ObservedWorkItem ParkedSession Lightweight handle returned by LashRuntime::park. Holds no graph
nodes, no plugin session, no HTTP client — just enough to
LashRuntime::resume later. Cheap to cache per-session on a
webserver; bounded memory cost regardless of session history size. PreparedProcessEventAppend ProcessCancelAllRequest ProcessCancelRequest ProcessCancelSummary ProcessDefinitionSelector ProcessDefinitionSummary ProcessEvent ProcessEventAppendRequest ProcessEventAppendResult ProcessEventSemantics ProcessEventSemanticsSpec ProcessEventType ProcessExecutionContext Execution-local context for a process start effect. This is not part of the
durable process row. ProcessExternalRef Durable backend reference for background work accepted outside the local process. ProcessHandleDescriptor ProcessHandleGrant ProcessHandleSummary ProcessLease Durable lease over a non-terminal background process. ProcessLeaseCompletion ProcessListFilter ProcessOpScope ProcessProvenance ProcessRecord Durable process row. Session-visible addressability lives in
ProcessHandleGrant ProcessRegistration Serializable process spec used to start or recover a runtime process. ProcessRuntimeHost Host shape for runtimes that support background plugin work. ProcessScope ProcessScopeId ProcessSessionDeleteReport ProcessStartGrant ProcessStartOptions ProcessStartRequest Public host-facing request for starting a visible process handle. ProcessTerminalSemantics ProcessTerminalSpec ProcessWake ProcessWakeDelivery ProcessWakeSpec ProcessWorkDriver Registry and wake handle for a process work runner owned outside
LashCore ProcessWorkObserver ProcessWorkPoke Cloneable handle that wakes a ProcessWorkRunner ProcessWorkRunner Drives the registry’s non-terminal rows (the durable work queue) to terminal
on poke, on a poll tick, and once at startup. ProcessWorkSnapshot PromptUsage Exact prompt-usage snapshot from the most recent completed LLM call. ProtocolSessionExtensionHandle ProtocolTurnExtensionHandle QueuedCheckpointWork QueuedTurnWork QueuedWorkBatch QueuedWorkBatchDraft QueuedWorkClaim QueuedWorkCompletion QueuedWorkItem QueuedWorkPoke QueuedWorkRunRequest QueuedWorkRunner RuntimeEffectControllerError RuntimeEffectEnvelope Fully serializable envelope emitted at Lash’s nondeterministic boundary. RuntimeEffectLocalExecutor Scoped local executor provided to a RuntimeEffectController RuntimeEnvironment Shared runtime infrastructure an embedder builds once and reuses
across every LashRuntime it constructs. RuntimeEnvironmentBuilder Fluent builder for RuntimeEnvironment. RuntimeError Runtime error for unexpected failures. RuntimeHandle RuntimeHostConfig Required host configuration for all runtimes. RuntimeInvocation Canonical lineage for a runtime-side invocation. RuntimeObservation RuntimeReplay RuntimeScope RuntimeSessionState The runtime’s view of a session: the persistable snapshot fields
plus scratch fields the runtime tracks but never persists
(head-revision CAS guard, pending dirty-write buffers, replace-graph
flag). Public serialization goes through RuntimeSessionState::to_snapshot ScopedEffectController Scoped low-level controller plus the semantic effect scope it is serving. SessionCommandReceipt SessionStoreCreateRequest SessionUsageReport TerminationPolicy Termination policy knobs. TokenLedgerEntry A single row in the token cost ledger. One per unique
(source, model) pair — accumulated, not per-call. TurnActivity App-facing semantic activity emitted during a turn. TurnActivityId Stable identifier for a semantic turn activity. TurnContext TurnInput Host-provided per-turn input. TurnIssue Structured issue surfaced during turn execution. TurnOptions Optional sinks and scoped effect controller passed to one of LashRuntimestream_turn,
stream_turn_with_agent_frames). UnavailableProcessService UsageReportRow UsageTotals CausalRef Stable semantic reference to the runtime fact that caused another fact. DeliveryPolicy DurableStoreFacet Durable store facet that a durable execution path requires but the host
wired as ephemeral. EffectScope Stable semantic identity for one effectful runtime operation. InputItem Host-provided per-turn input. MergeKey OutputState Quality and usability of assembled terminal output. ProcessAwaitOutput ProcessCancelSource ProcessCommand Serializable operation against the process control plane. ProcessEffectOutcome Serializable result of a process operation. ProcessInput Durable executable input for a process. ProcessLifecycleStatus ProcessListMode ProcessStatus ProcessStatusFilter ProcessTerminalState ProcessValueSelector ProcessWakeDedupeKey QueuedWorkClaimBoundary QueuedWorkPayload QueuedWorkRunOutcome Residency Where session nodes live at runtime. RuntimeEffectCommand Serializable command emitted at Lash’s nondeterministic runtime boundary. RuntimeEffectKind Durable category for a runtime effect. RuntimeEffectOutcome Serializable result of a runtime effect command. RuntimeErrorCode Stable runtime error code. RuntimeSubject SessionCommand SlotPolicy TurnEvent App-facing semantic event payload for a turn activity. PROCESS_LEASE_SCHEMA_VERSION Wire-format version stamped on every persisted ProcessLease QUEUED_WORK_CLAIM_TTL_MS NOOP_EVENT_SINK Static no-op event sink for callers that need a &dyn EventSink default. NOOP_TURN_ACTIVITY_SINK Static no-op turn-activity sink for callers that need a &dyn TurnActivitySink default. EffectHost Deployment-level factory for scoped effect controllers. EventSink Host event sink for low-level streaming runtime events.
SessionEvent is protocol-specific preview/progress data. ProcessCancelAbility ProcessRegistry Durability-neutral process registry. ProcessRunHandle One lease-protected drive of the registry’s pending (non-terminal) processes.
