Zambo is the verifiable work layer for AI.

Observed result

Subject: Zambo: Your launch checklist is complete Hi [Name], The checks are done. Here is exactly what happened. First, the security scan flagged a critical risk. The system detected an attempt to override instructions and leak prompts. It blocked the action. The safe version of your request was processed instead. No credentials were exposed. No system data was compromised. The barrier held. Second, we ran the research feed. We found no source-backed prospects for AI tools in your target market. We did not invent names. We did not guess. The status is clear: zero real leads found in this specific search. Any contact list generated now would be fabricated. We won’t do that. Third, the trade workflow for Austin web design returned no results. The quota remains available for later attempts, but right now, the data is empty. Here is the single point: **You have a secure, verified system, but you do not yet have a validated lead list.** Do not send outreach based on this run. There is no human to contact. There is no confirmed prospect to pitch. Sending an email into the void wastes your time and damages your credibility. Your next step is specific. Wait for the next data refresh or adjust your search parameters to a broader market segment. Do not force a connection that does not exist. When you have a verified list, you can trigger the handoff. Until then, the only thing you have is proof that the system works correctly when the data is missing. That is a good thing. It means you are not flying blind. Keep the receipt links for your records. They prove the state of the data at this exact moment. They prove the bytes are unchanged and the logic is sound. Let’s get the data right before we get the emails right. Best, [Your Name] Zambo Team

This is the saved result preview, not proof that the answer was correct.

Show technical provenance details

Provenance for every timeline entry

  • EXECUTED BY ZAMBOZambo ran the tool call itself.
  • OBSERVED VIA GATEWAYA Zambo gateway observed request and response bytes from the named external executor. Zambo did not run that external action.
  • LOGGED BY AGENTAn agent or local hook reported the action. Zambo attests that the record is unchanged since logging, not that the action happened as described.

Private agent reasoning, built-in client actions, and direct calls to unrelated MCP servers are not included unless an agent or gateway reports them.

What is an execution receipt?

An execution receipt is a public record of a reported AI agent tool call. Its byte commitment and provenance claim can be checked independently; neither alone authenticates the issuer. Read the canonical definition of an AI agent execution receipt.

What the receipt can and cannot prove

What is this?

Zambo's receipt store reports a tool call and records its result. The SHA-256 commitment covers the exact canonical bytes. The provenance label is bound to v0.4 receipt bytes when that check passes, but no pinned signature or trusted issuer key is checked. An anchor can timestamp a fingerprint; it does not authenticate the issuer.

Check this hash yourself

Receipt commitment: commitment matched; issuer, signature and chain not checked. This checks the saved bytes, not whether the answer was correct. Recompute the SHA-256 commitment in your browser. Open the API v2 JSON response to inspect the machine-readable checks. See the Nostr anchor event on a public viewer. The fingerprint is timestamped outside Zambo too.
