Workflow Execution & Configuration Snapshots
What a workflow execution records, and why four immutable snapshots make every run reproducible.
The Execution Status Model
The execution status state machine — the six statuses, who sets them, and the transient-vs-permanent distinction.
Threshold Enforcement Model
How the platform enforces per-workflow cost and time limits through three cooperating layers.
The Background Execution Reconciler
The backstop service that keeps platform state truthful against the engine — its invariant, decision table, and single-runner design.
Cost Model: Execution vs. Entity Production Cost
How the platform computes cost — core-owned, at ingestion, from current pricing — and how it aggregates from step to entity.
