Receipts observed

Every truth check is sealed into a receipt: a canonical JSON record of what was asked, what came back (as digests), what the primary source said, and when — signed with Ed25519. Anyone can verify a receipt with the public key below and ~40 lines of standard-library Python. Trust is not requested; recomputation is offered.

Verify one yourself

Fetch a receipt as JSON (append .json to its URL), then check that ed25519.verify(public_key, canonical_payload_bytes, signature) holds — our ed25519.py is a single dependency-free file implementing RFC 8032, in the repository. The payload's checked_at and meaning fields are inside the signature on purpose: a receipt is a dated observation, not a warranty.
