Agent Day Pass payment confirmed · saved and checkable

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: FAIL; The receipt schema version is missing or unsupported; provenance binding was not accepted.
• Metadata binding: LEGACY; legacy receipt, metadata is not cryptographically bound
• 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: 2026-09-19T01:49:12.943Z; external immutability is not checked

Relay hints: unavailable

Anchor status "unavailable": The anchor status is not available.

Relay publication is separate from receipt integrity. When the original signed event is available, Zambo retries pending, partial, or failed anchors about once a minute. Relay acknowledgements are external, so there is no guaranteed completion time; the receipt remains checkable from its saved bytes and verification link.
