- core/derive/ssh.ts: BIP-85 app 32 entropy used directly as the Ed25519 private key, serialized as PKCS#8 and SubjectPublicKeyInfo PEM. Both DER shapes are fixed for Ed25519, so they are emitted from literal prefixes rather than adding an ASN.1 dependency to the crypto path. - Output matches Python's `cryptography` byte-for-byte across two seeds and three indices, including PEM line wrapping. - CLI: `entry add ssh`, reveal (private key PEM), and `entry ssh-public` which prints the public key without touching secret material. The OpenSSH authorized_keys line is a TS-only convenience -- Python emits only PEM, which ssh(1) cannot consume directly -- and is marked as such in the compatibility matrix. - Cross-impl phases A and B now include an ssh entry in both directions. One harness fix: PEM values carry a trailing newline that the CLI capture strips, so the cross-impl comparison normalizes trailing whitespace. The unit tests still compare exactly. 170 core + 46 CLI tests green; 16/16 cross-implementation checks green. Co-Authored-By: Claude Fable 5 <[email protected]>
