Research direction
Start with zip2john m.zip and compare its output with zipinfo-v.txt and p7za-m.zip.txt; read john-list-build-info.txt for the reported build context. Done means zip2john generates a usable hash for the pkAES-256 Deflate archive without the current unsupported-compression message.
