Marsen n8n human approval acceptance lab v1
Tested: 28 September 2026; n8n 2.35.4.

Download workflow.json. In a disposable n8n workspace, import the file into a
new workflow. Keep it inactive. Choose Execute Workflow. Inspect the final
Verify outcomes node: 13 items should have passed: true.
The graph is Run lab -> Synthetic cases -> Validate approval -> Simulated CRM
-> Verify outcomes. It uses built-in Manual Trigger and Code nodes only.
No credentials, webhooks, outbound requests or real CRM writes are needed.

Reproduce with Docker (from the directory containing workflow.json):

docker run --rm --network none \
  -v "$PWD/workflow.json:/lab/workflow.json:ro" \
  -e N8N_DIAGNOSTICS_ENABLED=false \
  -e N8N_VERSION_NOTIFICATIONS_ENABLED=false \
  --entrypoint /bin/sh docker.n8n.io/n8nio/n8n:2.35.4 \
  -c 'n8n import:workflow --input=/lab/workflow.json && n8n execute --id=marsenApprovalLabV1 --rawOutput'

The command uses a new ephemeral n8n database. It does not mount your live
n8n data. The first run may download the image. A successful final output
contains status: success and 13 Verify outcomes items with passed: true.

The fixture clock is numeric and deterministic: event.at=1000 and
proposal.expiresAt=2000. Equality expires. These are test clock values, not
measured wait durations. Reviewer strings are mock authorization inputs;
they do not authenticate a person. All proposals and receipts exist inside
one execution and are discarded. The file is an acceptance lab, not a
production approval template. Code-node source copies accompany the import.

Production work still requires an authenticated reviewer, durable proposal and
receipt storage, atomic decision ownership, a real destination API, monitoring,
and tests spanning separate deliveries, concurrent workers and restarts.
Never accept a reviewer identity asserted by a public request body.
Do not replace the simulated destination with a real writer until those
boundaries are implemented. Timeout reconciliation is simulated, not an
external API guarantee. A Wait-node timeout waking an execution is not approval.
