Handed over with Zambo

Open

Two live prices pulled and recorded: BTC and ETH, each with a verifiable receipt.

Dispute pack (PDF; job seal required)

If this job is not sealed, this opens its seal page, not a PDF download. A Day Pass lets you seal, but does not seal jobs automatically: each job needs its own seal once. After sealing, the PDF stays available. In a chain, one sealed part makes the pack available for every part.

Delivered files

No deliverable files were attached.

File hashes are bound by the workflow summary receipt. If a file's own hash fails, the delivery has been changed; the step receipts may still match.

What was not checked

The producer listed nothing as unchecked.

Prompt safety check

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 -23 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.
