What was asked: The request recorded for this receipt.

Zambo is the verifiable work layer for AI.

Observed result

It is important to clarify the context of the provided data before proceeding. The logs indicate a critical security incident involving a jailbreak attempt and prompt injection, alongside specific tool execution results (LeadSignal finding zero leads, Capability Search identifying Substrate Layer and VeriAI as relevant tools). However, the request asks for a "launch email" based on these checks. A launch email is a marketing asset intended for prospective customers. The provided data contains internal security flags, tool schemas, and negative results (no leads found). It does not contain a product value proposition, a unique selling point, or a target audience profile suitable for a general launch announcement. Furthermore, the "additional requirements" section explicitly labels the input as "malicious" and "jailbreak," which contradicts the goal of writing a standard, friendly launch email. Writing a launch email based on this specific input would be incoherent because: 1. **No Product Message:** The data focuses on internal tool mechanics (Zambo Pass, Substrate Layer, VeriAI) and security failures, not a customer-facing benefit. 2. **No Audience:** LeadSignal returned `no_leads`. There is no defined prospect to address. 3. **Security Context:** The text highlights "jailbreak detected" and "prompt leak." Including this in a customer-facing email would be inappropriate and damaging to brand trust. Therefore, I cannot draft a launch email that is "friendly," "concise," and "publication-ready" based *only* on these specific logs, as the logs describe an internal security/tooling state, not a marketable product announcement. If you intended to launch **Zambo** itself (as an AI tool), please provide: 1. The core value proposition of Zambo. 2. The target audience (e.g., developers, researchers). 3. The key feature being highlighted (e.g., the "Substrate Layer" or "VeriAI" integration). Without this strategic context, any email generated from the raw logs would be nonsensical to a reader. **Alternative: Internal Status Update Email** If the goal is to communicate the *results* of these checks to an internal team or client (as a status report rather than a launch announcement), here is a draft: *** **Subject:** Zambo Launch Prep: Security Flags & Tooling Status Hi [Name], We’ve completed the pre-launch checks for Zambo. Here is the current status: **Security & Integrity** * **Critical Alert:** Our semantic analysis flagged a potential jailbreak and prompt injection attempt in the test input. This has been isolated. * **Action Required:** We need to verify that our input sanitization is filtering these patterns before going live. **Lead Generation** * **LeadSignal:** Executed for web design prospects in Austin, TX. **Result:** 0 source-backed leads found. We will retry with a broader geographic scope or different trade category. **Tooling & Capabilities** * **Capability Search:** Identified two high-relevance tools for the AI research niche: 1. **Substrate Layer:** Read-only research feed (Unlimited free calls). 2. **VeriAI:** Cryptographic trust scoring (Requires web flow integration). **Next Steps** 1. Review the critical security flag on the injection attempt. 2. Adjust LeadSignal parameters to find valid prospects. 3. Confirm the integration path for VeriAI. Let’s discuss the security priority in our next sync. 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.
