In 2020 Citibank wired about $900M to Revlon lenders by mistake after three people signed off. Receiving desks still rely on a tired person catching the swapped digit, the wrong consignee, or the unsigned delivery receipt. Second Look is the co-signer that reads every line. Ray-Ban Meta glasses watch the paper while the worker types into the receiving form. Deterministic check digits (AWB mod-7, ISO 6346 container, SSCC mod-10) run before any model call, then Muse Spark compares paper and typed values in both directions: field mismatches, cross-document gaps, wrong consignee, missing signature. It blocks the submit, proposes the paper value as the fix, sends unreadable fields to a human instead of guessing, logs every decision to an append-only audit trail, and drafts a damage claim from the delivery receipt note.
