A public stream of HMAC-signed agent receipts as they're produced by the platform. Every row is a real receipt — click through to the full canonical projection, run a live verification against /api/verify, or paste the signature into your own browser to check it yourself.
Receipts marked "public" by their owners are enumerable here. "Unlisted" receipts stay share-by-link; "private" receipts never appear in any public feed. Read /spec for the full visibility contract.
