  "scope": "Actual n8n 2.41.5 native CSV, Set, If and HTTP Request nodes, run through imported CLI workflows; deterministic placeholder drafts and a fault-injected localhost idempotent sink. No external account, model generation, hosted connector or public publication was tested.",
  "conclusion": "All six native workflow control cases passed. Three CSV rows produced exactly two approved local draft files and one rejection. Missing approval and an external action scope were blocked. A permanent output error stopped after three 503 attempts; environment access was denied without leaking the synthetic marker. Retrying C also repeated A three times: the local sink deduplicated those requests by ID, so this result does not claim that n8n automatically makes external connector side effects idempotent.",
