Verifiable receipt 3cc4449a - handover result | 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 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.

Verification checks

• SHA-256 commitment: Checked independently against the exact decoded bytes
• Provenance binding: PASS; The metadata claim is consistent with the verified receipt bytes; issuer is not authenticated.
• Metadata binding: PASS; metadata_hash matches the canonical metadata block.
• Issuer authentication: NOT CHECKED; no pinned signing key or trusted issuer was supplied
• Signature: NOT CHECKED; no Ed25519 signature or pinned key is supplied
• Chain: NOT CHECKED; no append-only chain proof is validated
• Stored timestamp: 2026-10-18T14:02:03.840Z; external immutability is not checked

Committed provenance claim

EXECUTED BY ZAMBO

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.
