Private facts required to distinguish a stable loop boundary from an uncertain model attempt. ModelAttemptStarted is written before polling ModelBackend::start.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

LoopBoundaryCommitted

Fields

next_model_round: u64

usage: ModelUsage

tool_call_count: u64

last_response: String

supporting_event_ids: Vec<AgentEventId>

ModelAttemptStarted

Fields

round: u64

request_id: ModelRequestId

request_digest: Digest

max_output_tokens: Option<u64>

context: GenericModelContextTrace

ModelAttemptObserved

Fields

round: u64

request_id: ModelRequestId

observation: GenericModelObservation

ModelContextRejected

A definite capacity rejection, before any model usage or content. This closes the attempt without executing tools and durably reserves a smaller input or output budget, including after restart.

Fields

round: u64

request_id: ModelRequestId

retry_number: u32

input_budget_tokens: u64

output_budget_tokens: Option<u64>

error: ModelError

ModelRetryScheduled

A retry within an open logical attempt, before any non-usage event was observed. Recovery still treats an open attempt as interrupted; this fact does not authorize replaying a model request after process loss.

Fields

round: u64

request_id: ModelRequestId

retry_number: u32

delay_ms: u64

error: ModelError

observed_usage: Option<ModelUsage>

Last reported usage snapshot of the failed attempt. Missing fields remain unknown; this does not certify the request’s final cost.

WorkflowAttemptStarted

Written before entering the Workflow DAG executor. Once present, a missing durable Workflow output is intentionally outcome-unknown and must never be reconstructed by rerunning the DAG.

Fields

round: u64

request_id: ModelRequestId

call_id: ModelToolCallId

arguments_digest: Digest

CommandCommitted

Fields

command: AgentCommandEnvelope

outcome: ProviderCommandOutcome

approval_capability: Option<ApprovalCapability>

ProviderEventsCommitted

Provider drafts are persisted before they enter the live Provider stream. A delivery batch may contain OutputCommitted followed by the single terminal DeliveryCommitted event.

Fields

events: Vec<AgentEventDraft>
