Bit-by-bit comparison of Ventoy vs hiperiso USB partitions showed one remaining structural difference: Ventoy uses 32MB ESP partition, we used 64MB. Installer's mkfs.vfat also repeatedly failed with 'too many clusters' because 64MB/512-byte-cluster exceeds FAT16 max cluster count (65524). Reducing to 32MB matches Ventoy exactly: - src/gui/Core/hiperiso_define.h - src/plugson/src/Core/hiperiso_define.h - src/hisocli/hisocli.h (HIPERISO_EFI_PART_SIZE) - src/installer/tool/hiperiso_lib.sh (HIPERISO_SECTOR_NUM=65536) - scripts/package_release.sh (ESP image size) Binaries + payload rebuilt.
