feat(panic): FUCK [panic] mode=strict|fallback + realtest image variant
...
- UTSM panic_full returns in fallback mode (logs [PANIC:FALLBACK] + code + hit
count); panic_halt keeps always-halt sites (CPU exception, VMM-E11 LA57,
VMM-E15 DSK jump, UTSM-E42 test hook). Call sites given safe continuations.
- Mode passed to DSK/FirstInit/login/desktop via DSK_BOOT_FLAG_PANIC_FALLBACK;
DKM kernel_api.panic / kern.log.panic return to driver; ext4 fatal aborts the
op via setjmp/longjmp and DSK falls back to FAT32 ESP.
- build.ps1/Makefile: dev=strict, release=fallback, new realtest (release
options + strict); default -Variant all; serialized iso packing under -j.
- Fix '*/' inside comments (dkm.h, kernel_api.h, bus.c) that broke the build.
- Includes pending work: dkm_bus service bus, mt7920/wlan drivers, desktop
files/startmenu/prank, pe-tools, diskinfo, docs.

feat: FS-E strict filesystem mode - ext4 rw driver, FAT32 big-disk fix, forced re-login
...
- 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).

feat: D4 DKM colored log prefixes - every driver has its own temper
...
- log.c: color context (log_set_color / log_color_enable); ANSI only goes to serial, BOOTLOG.TXT buffer stays clean plain text
- kernel_api.c: dkm_log_set_driver() — driver-name FNV-1a hash into an 8-color bright ANSI palette, deterministic per driver
- load sites (dkm_core builtin + boot_modules external) set color around driver_init and clear after
- FUCK [debug] color_log gate (dev=1, release=0)
- QEMU verified: 1150 colored lines, per-driver stable colors (.build_tmp/qemu_serial_d4color.log)
