Show technical provenance details

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 the receipt can and cannot prove

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.
