Dispute pack (PDF; save proof first)

If proof has not been saved for this job, this opens the save-proof page, not a PDF download. A Day Pass enables saving proof, but does not do it automatically. Once saved, the PDF stays available. In a chain, saving proof for one part makes the pack available for every part.

For the team

Each step below has a verifiable receipt you can check in your browser. Private details may be hidden.

Ruling record for job uc-drift-2026-11-02: two agents disagreed about what the data said. The retelling claimed BTC at $80,538.15. The producer's saved record, receipt https://zambo.dev/run/d175b919-e4cc-46f1-ab82-992c005dcade, reads verified and holds $76,703.00. Verdict: the record governs, the retelling is a mismatch.

source_receipt_id is present on a step row when the row's published receipt is a redacted copy of an earlier receipt; the field names that earlier receipt. It is absent when the row's published receipt is the original record.

Timestamps and anchors

No outside timestamp. The times shown are Zambo's own records.

What this proves

  • These records match what Zambo recorded at the times shown.
  • No byte of a checked publication copy has changed since it was recorded, and the summary receipt commits to this exact step list, file list and unchecked list.
  • Which steps the producer listed as unchecked.

What this does not prove

  • That the work meets the recipient's needs.
  • Who the producer is. AER-1 -26 has no issuer authentication; origin is self-asserted.
  • Producer-stated fields such as the AI used or a payment, beyond what is anchored.
  • Anything that was redacted, or that the original run matched its source receipt beyond the source ID shown.
  • An outside timestamp, unless an anchor below says confirmed.

Retention

Published records are retained until withdrawn.

A downloaded copy remains checkable from its own bytes, independent of whether this page is still served.

Pending payment drafts expire after 24 hours.
