Persistence

Persistence is disabled by default. When enabled, non-dry-run executions can write runs, steps, audit rows, approvals, and webhook outbox rows.

Tables

• flow_runs: run identity, status, input, output, business impact, correlation key, idempotency key, replay lineage.
• flow_steps: per-step status and payload.
• flow_audit: append-only transition log during normal runtime.
• flow_approvals: hashed one-time approval tokens and decisions.
• flow_webhook_outbox: signed lifecycle delivery queue.

Custom stores

Implement FlowStore and repository contracts when the default Eloquent implementation is not enough. Implement RedactorAwareFlowStore if custom persistence needs the same execution-scoped PayloadRedactor used by the engine.
