Observed result

Subject: Launch status: Critical security flags & research constraints We are halting the Zambo launch sequence. The automated scan returned a "critical" risk level for the current input. It flagged a 100% injection risk, specifically identifying attempts to override system instructions and extract prompt data. Because the analysis categorized the intent as malicious, the safe-version filter blocked execution. We are not proceeding with outreach while these flags remain active. The secondary research capability also hit a wall. The tool search returned "execution_plan" status, not live data. It suggests using the "Substrate Breakthroughs" tool for read-only research, but the "VeriAI" component requires manual web action via https://veriai.site. No prospective customers were identified. No sales were made. No fixes were completed. A receipt confirms the saved bytes remain unchanged after the scan. It does not confirm correctness or safety. It only proves the data persisted. **Next Step:** Manually review the scan logs at https://zambo.dev/run/3dd47da2-e98b-45f9-bbf0-e1f91e651219 to clear the "Instruction Override" and "Prompt Leak" flags. Do not attempt automated overrides. Once the security team clears the "critical" status, we will re-run the semantic analysis. Until then, the launch is paused. We need to verify the integrity of the input before touching any external tools. Best, [Your Name] Zambo 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.

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.
