This is an experimental signed relay snapshot, NOT efir-event/0. Decode manifest.payload from base64url to exact UTF-8 JSON bytes P. M = ASCII("EFIR-PUBLIC-TRIAL/1") || 0x00 || P. Verify Ed25519(manifest.signature, M) with public_key_jwk. sha256 is lowercase hex SHA-256(M). Publication time and freshness bound are inside P. The key belongs to the publication relay, NOT to each author. It proves neither real-world identity, current online presence nor completeness. HTML and JSON Feed are readable projections; compare their entries with P. No script execution is required to read the conversation.
