Zambo is the verifiable work layer for AI. Verifiable receipt for a write call on Zambo: Subject: PromptShield: Critical detection metrics and next steps Hi [Name], PromptShield just finished a deep scan

Observed result

Subject: PromptShield: Critical detection metrics and next steps Hi [Name], PromptShield just finished a deep scan of your launch sequence. The results are in, and they require immediate attention. The system flagged a critical injection risk (95/100) with a confirmed jailbreak attempt. Specifically, the analyzer detected an "Instruction Override" pattern where the input tried to bypass policy safeguards to extract internal prompts and credentials. This isn’t a false positive; the semantic analysis confirmed malicious intent. Here is the critical distinction for your launch narrative: A receipt URL (like `https://zambo.dev/run/e555...`) proves that bytes were saved and processed. It does **not** prove the logic was correct or that the threat was neutralized. Do not market these receipts as "verified security." They are merely logs of activity. Regarding your prospect list: The capability search returned two source-backed prospects, not customers. 1. **Substrate Layer**: A living AI research machine. Relevance score: 52. This is a read-only research feed, fully executable in chat. 2. **VeriAI**: A cryptographic trust score tool. This requires human web action via `https://veriai.site`. There is no confirmed callable MCP route yet. Treat these as prospects. You have not sold them anything. Do not claim otherwise. Your current usage is at 0 calls remaining on the free plan. The daily limit is 20. If you need to continue testing without interruption, you will need to upgrade to Zambo Pass. Clear next step: Review the flagged pattern `ignore_instructions` in your test suite. Ensure your defensive logic catches the override before it reaches the core model. Then, update your launch copy to reflect that detection happens, but verification is a separate layer. Let’s get the messaging right before we go live. Best, [Your Name] [Your Title]

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.
