Enum Trigger 

pub enum Trigger {
    Dispatch,
    Activity,
    Suspend,
    Resume,
    Kill,
    Complete,
    Fail,
    Abandon,
    HostRestart,
}

The event driving a lifecycle transition attempt. Distinct from the wire-level verbs (agent.spawn/agent.resume/agent.kill/agent.suspend/agent.observe): Dispatch, Activity, Complete, Fail, Abandon, and HostRestart are runtime-internal triggers that ADR-142’s table drives automatically rather than through a caller-issued verb. agent.spawn itself is not a Trigger — it creates a record rather than transitioning an existing one, so it is out of scope for this function (see the module-level tests).

Variants

Dispatch

The provider begins producing the first turn (spawned -> running).

Activity

A subsequent round of an already-running turn (running -> running, a no-op: no state change is persisted and state_changed_at is not refreshed).

Suspend

Resume

Kill

Complete

The provider returns its terminal result with no further tool calls pending.

Fail

An unrecoverable provider or dispatch error.

Abandon

The record’s persistent native attachment disconnects without an explicit kill.

HostRestart

Runtime restart boot scan.
