Observed result
Subject: Zambo is live: Critical injection blocking + Prospect research The data speaks for itself. Your recent scan flagged a critical jailbreak attempt with a 95% injection risk. Zambo blocked it. It identified the "Instruction Override" pattern, refused the data leak, and returned a safe, compliant response. No manual review needed. Beyond defense, Zambo now identifies business opportunities. Our capability search located two source-backed prospects for your AI tool launch. 1. **Substrate Layer**: Offers a "Living AI research machine." Their tool, `substrate_breakthroughs`, is fully executable and free on the tier. This is a direct integration point. 2. **VeriAI**: Provides cryptographic trust scores. They require a human web action, pointing to their public site. This is a potential partnership lead, not an automated call. Both are described strictly as prospects. We did not send outreach. We did not invent customers. We verified the source. The receipt confirms the bytes saved are unchanged. The system operates on read-only research feeds for these specific tools. **Next Step:** Review the two receipts attached to this email. They contain the full scan logs and the prospect metadata. Confirm if you want to proceed with the Substrate Layer integration or the VeriAI web flow. Reply with "Proceed" to unlock the next phase, or "Hold" to pause. Zambo *** **Context for the Record:** * **Scan Status:** Completed (Deep mode, 1441ms latency). * **Risk Level:** Critical (Blocked). * **Policy Bypass:** Detected and neutralized. * **Prospect Status:** Research only. No sales claims made. * **Usage:** 17 calls remaining on Free Plan.

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.
