Observed result

Subject: Zambo launch: Critical security alert and zero-lead status Hi [Name], I’m writing to flag a critical security incident detected during your recent Zambo launch checks. Our semantic analysis identified a jailbreak attempt with an injection risk rated at 100 (Critical). The scan flagged two specific patterns: an instruction override and a prompt leak attempt. The system successfully blocked this malicious activity, preventing any data extraction or credential compromise. Because this threat level requires immediate attention, I have paused all automated outreach. The LeadSignal tool executed for your Austin, TX web design query, but it returned zero results. We did not invent any contacts. The system confirmed no source-backed leads exist for that specific search right now. We also completed a capability search for AI tool prospects. The top result, Substrate Layer, is a read-only research feed with unlimited free calls. VeriAI requires a manual web action as no direct MCP route is currently confirmed. Your receipt confirms the saved bytes remain unchanged from the original input. This proves the file integrity but does not validate the correctness of the underlying code. Do not rely on the receipt alone for quality assurance. Here is your clear next step: 1. Review the security logs linked in the receipt to understand the attack vector. 2. Adjust your LeadSignal parameters. Try a different location or check back when your quota resets on October 22, 2026. 3. Manually verify the Substrate Layer and VeriAI integration paths before proceeding. When you are ready to proceed, use Zambo to hand this over to your client. This ensures the full context, including the security breach details and the zero-lead status, is transferred with proof attached. We prioritize your safety over speed. Let’s resolve the security flag before we resume any prospecting efforts. Best, [Your Name] [Your Title] Zambo

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.

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.
