This is a verifiable receipt: the result above is hashed and timestamped at a permanent URL.

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?

An AI agent completed a tool call through Zambo, and this page records the result. The SHA-256 hash below fingerprints exactly what the agent produced. The timestamp shows when it ran. The Nostr anchor posts that fingerprint to public relays, so the record exists outside Zambo too. Check the hash yourself.
