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?

This page records a report received from an agent or local hook. The SHA-256 hash below fingerprints the logged record. The timestamp shows when Zambo received it. This page does not establish that the reported action happened.

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.
