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 this receipt?

This is a verifiable receipt for a journal entry. It confirms receipt, redaction, timestamping, and chaining. It does not attest to execution.

What is this?

Zambo's receipt store reports a journal entry from an agent or local hook. The SHA-256 commitment covers the receipt bytes. The provenance label is only a claim, not proof of issuer identity or that the reported action happened.

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: 2026-10-22T07:32:55.657Z; external immutability is not checked

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.
