Observed result

Subject: Zambo is live: 51 AI lifeforms and cryptographic trust Hi [Name], Zambo is officially launched. We built it to solve the two biggest friction points in modern AI workflows: reliable research generation and verifiable output integrity. We focused on tools that work immediately, without complex setup or hidden costs. First, **Substrate Layer**. This is a living AI research machine featuring 51 distinct lifeforms designed for adversarial research. It’s fully executable and runs on an unlimited free tier. You can call it directly via `substrate_breakthroughs({})` to get a read-only feed of breakthroughs. No approval needed. No per-call fees. Just start. Second, **VeriAI**. This assigns a cryptographic trust score to any AI-generated output. We know the "black box" problem is real. VeriAI bridges that gap by giving you a verifiable metric for quality and origin. Note that this tool currently requires a human web action at veriai.site, as a direct MCP route is not yet confirmed. We have completed the launch checks. A receipt exists at [zambo.dev/run/53db5a86-62fc-42db-96c5-1fde9d26ece9] confirming the saved bytes of this build. However, a receipt only proves the code is unchanged; it does not guarantee correctness. We are treating these as prospective solutions, not finished products, and we are relying on your real-world usage to validate their effectiveness. We are not claiming these tools are perfect. We are claiming they are ready for you to test. **Next Step:** Run a single call to `substrate_breakthroughs` today. If the output resonates with your current research needs, we want your feedback. If it doesn’t, tell us why. We are building in public, and your signal is the only metric that matters right now. 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.
