Automation Acceptance Replay Harness

Replay automation traces against explicit rules for required steps, order, retries, approvals, idempotency, external side effects, duration, and terminal success.

What problem does Automation Acceptance Replay Harness solve?

An automation can end on a green node while a required step failed, an email or write happened twice, an external action lacked idempotency, a gated action skipped human approval, or the execution log cannot support client acceptance.

What it returns

A representative input and result

fixture-backed sample
input Contract: required ingest,classify,approve,send,record; email_sent requires idempotency and prior human_review; max retries 2. Trace: email_sent succeeded twice with side_effect_key email:lead-99; first send had no idempotency key; no approved review event; classification failed; terminal completed.
result Recommendation: REJECT Critical: duplicate successful email side effect. Critical: missing idempotency key and human approval. Critical: terminal completed after required classification failed. High: required approval and record steps missing; retry limit exceeded.

Questions

Does it execute or replay my live workflow?

No. It replays the logic of acceptance checks over an exported trace. It does not call connectors or change external systems.

Which automation platforms work?

Any platform can work after its execution records are mapped to the documented CSV fields, including n8n, Zapier, Make, agent frameworks, and custom systems.

How does it detect a duplicate side effect?

It flags more than one successful allowed side effect sharing a side-effect key or idempotency key inside an execution trace.

How is human approval represented?

A gated action must be preceded by an event with event_type human_review and status approved in the same execution.

Does ACCEPT prove the workflow is correct?

No. ACCEPT means the supplied executions cleared the declared contract. Coverage, log completeness, semantic output quality, and external state remain separate questions.

Does it need my n8n or Zapier credentials?

No. The helper runs locally on exported files and requires no platform, connector, browser, or network access.
