Provenance for every timeline entry

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?

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.

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.

API v2 status: verified. This status summarizes the v2 commitment and provenance checks; it does not prove 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.
