  "description": "A node inside a nested loop must still be able to reference the OUTER loop's item. Reproduces the Email OCR failure of 2026-09-04: build_email sits in a loop over one email's attachments, nested in a loop over emails, and {{email.from}} resolved to empty - so the reply was addressed to nobody and the send failed with \"At least one recipient is required\". The inner loop deliberately uses a different item variable name, and the assertion checks both are visible at once.",
