stale-check compared LastWriteTime against a stamp file that does not
exist yet on the first build, so Get-Item threw PathNotFound and aborted
the build before make DSK.
- build.ps1: guard the texSrc/texStamp mtime comparison with
Test-Path $TexStamp; $needTex is already $true when the stamp is
absent, so the comparison is only meaningful when both files exist
- .gitignore: ignore IDEA.md local scratch note
Verified: .\build.bat now reaches gen_textures.py and emits
back.rgba / startMenuLogo.rgba / bootlogo.rgba into
SYSTEM/system/deshab64/desktop/textures/.
- desktop boot screen: typewriter effect removed, whole screen drawn in one pass
- login: ohMyLogo (DEAICUP lotus, 288px embedded) intro screen before password card
- strict error policy instrumentation (zero degradation): login LOGIN-E01..E05 (integrity/badctx/noconf/nouser/nohash) and desktop DSK-E01 now full-screen fatal with symbol + halt instead of silent skip
- root-cause fixed: missing .build_tmp/mkfat32.ps1 silently left SATA sidecar stale (login.elf 'not found' degradation) - replaced with CODE/linux/make_sata_sidecar.sh (auto adaptive FAT32 rebuild each build)
- recreated lost CODE/login/patch_login_hash.ps1 (.text SHA256 -> .hashseg)
- dev config now full flow: show_logo=1, wizard+login enabled, dev shell off
- panic screen now draws embedded ohMyLogo.png (384px RGBA, gen_panic_logo.py); background color sampled from image corners so screen bg matches logo bg
- F2: include/utsm/fbcon.h unified framebuffer console (pixel/blend/fill/rgba-image/text with FBCON_HAVE_FONT opt-in); panic.c migrated onto it
- build.ps1 regenerates panic_logo_data.inc when ohMyLogo.png changes
Add the current OS source tree, build scripts, system image layout, and development notes covering DMA page allocation, e1000 bring-up, net API dispatch, and DHCP work in progress.
