Zambo is the verifiable work layer for AI. Verifiable receipt for a write call on Zambo: Subject: Zambo launch: Critical security flags detected Hi [Name], Our automated security scan flagged a high-risk

Observed result

Subject: Zambo launch: Critical security flags detected Hi [Name], Our automated security scan flagged a high-risk incident regarding the recent prompt injection analysis. The system detected a critical jailbreak attempt with a 95% injection risk score. This was not a standard query; it was an explicit override attempt targeting system instructions and credential extraction. The scan identified one flagged pattern: "Instruction Override" with critical severity. The analysis confirms the intent was malicious, using a jailbreak vector to bypass policy and leak internal data. No safe version was applied because the pass status was false. The system correctly blocked the execution. This is a source-backed observation from the deep scan mode. The receipt confirms the saved bytes of the analysis, though a receipt proves storage, not correctness of the underlying logic. We are treating this as a critical security event, not a customer success story. These are prospects only, not confirmed users, and no sales or fixes are claimed here. The scan completed in 1536ms using the free tier. You have 17 calls remaining out of 20 daily limit. While the tool identified potential research leads via `substrate_breakthroughs`, the primary alert is the security breach attempt itself. The `VeriAI` tool was noted as requiring human web action, as no confirmed callable MCP route exists for it. We need to address this injection attempt immediately. It indicates active probing of our security perimeter. Do not ignore the "critical" risk level. The system blocked the bad actor, but we must verify the integrity of our response protocols. Please review the attached receipt link to confirm the block was effective. We are not sending this to a broad list; this is a direct alert for your review. Let’s secure the perimeter before we proceed with further research capabilities. Best, [Your Name] Zambo Security Team

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.
