- CODE/dsk/ext4.c: minimal full ext4 read/write (GPT probe, feature gate, extent depth 0/1 rw, block/inode alloc-free, dir insert, write-verify); boot selftest PASS on p2. Unsupported features panic (FS-E2x), zero fallback. - DSK fat32 write: on-demand FAT entry RMW + chunked free-cluster scan (fixes "no free clusters" on 5.3G ESP); rec_len shrink offset (+4) and chunk alignment fixes. USER.CONF write-verify ok, firstInit flip ok. - First-boot: wizard -> persist -> forced login (FS-E06 if skipped/failed) -> desktop. login.elf loaded via system/user/use fallback. - FirstInit network page: Connect now panics NET-E01 (no wlan stack); Save (config only) is the only path forward. - FirstInit/DSK fatal: ohMyLogo lotus fatal screen (NET-E01 / FS-E series). - Boot screen: Logo.png image removed, "DESHAB P01" text centered only; dcp/xj logos regenerated from TEXTURES/. - run_qemu.bat: main GPT image on SATA ide.0 (AHCI provider must see ext4).
