Enum AuditTrailScope 

pub enum AuditTrailScope {
    Full,
    Own,
    None,
}

How much of Message::audit_trail a step’s snapshot carries.

This is the knob for the quadratic term of trace size: under AuditTrailScope::Full, step i clones i audit entries, so an N-task workflow retains N*(N+1)/2 of them.

Variants

Full

Every entry accumulated so far — the historical behaviour. Total entries across the trace grow as N*(N+1)/2 in task count.

Own

Only the entry this task produced, and none for a TaskOutcome::Skip step. Linear in task count, and sufficient for the dataflow-ui step debugger, which reads only the last entry.

None

Empty audit_trail in every snapshot.
