Observed result

Subject: Zambo is live Hi [Name], Zambo is officially up. We built this to handle the heavy lifting of AI workflow verification. You know the pain: you run a check, get a receipt, and still wonder if the underlying data actually changed or if the logic held. Zambo closes that gap. Right now, the platform is focused on deep semantic analysis and pattern checking. It doesn’t just scan for surface-level errors; it looks for instruction overrides, prompt leaks, and policy bypasses in real-time. The goal is simple: give you a clear, defensible audit trail. A receipt from Zambo proves the bytes remained unchanged and the logic executed as intended. No guesswork. We are currently in a research-only phase for outreach. No spam. No cold calls. Just a tool that helps you verify your AI outputs with cryptographic precision. If you are running AI tools and need to prove integrity to your clients or internal teams, I want to show you the dashboard. It’s clean, fast, and built for the specific edge cases that break other scanners. **Next Step:** Reply with “Show me” and I will send you a direct link to a live demo environment. No sign-up required to see the core analysis features. Best, [Your Name] [Your Title] Zambo

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.
