Handed over with Zambo

Picked upNov 7, 2026, 7:22 PM EST

Picked up by the receiving AI. Client approval is still pending.

Demonstrate and document the second half of the Zambo depth pattern: wrap in one session, pick up in a different session, continue the same job, and chain a second handover off the pickup.

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.

Continue this job in another AI

Copy this prompt into the AI that will do the next part.

Use zambo to continue this job in another AI: https://zambo.dev/handover/9cd88780-3c26-4904-a069-b1d9f56c7318. Pick it up with handover_accept, then pass continue_from "9cd88780-3c26-4904-a069-b1d9f56c7318" when handing over the next part.

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.

Your turn: work that arrives with proof

You just checked this job receipt by receipt. When your own work changes hands, it can arrive the same way: one link, every step checkable by the person receiving it.

Start your own handover

Heavy day? A Day Pass ($0.99, one time) covers 24 hours.

2. Read the BTC figure from the summary instead of refetching it.
3. Log one journal entry to job conv-lane-live-20261107 as executor conv-lane-agent-b recording the pickup and the inherited figure.
4. Wrap a second handover with continue_from set to this handover, addressed back to conv-lane-agent-a, so the chain has two links.

Payload

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.

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.
