bee.nvidia.mode=gsp-off loads the driver with NVreg_EnableGpuFirmware=0 and
skips nvidia-uvm/nvidia-modeset, so CUDA (nvbandwidth/dcgm/nccl) can't run —
and on Hopper H200 GSP is effectively mandatory anyway, so the mode is dead
weight in this test image. Remove it from every boot entry. fail-safe is now
bee.nvidia.mode=normal pci=realloc iommu=pt, so the GPUs come up with uvm and
the GPU test actually runs under iommu=pt (the point of the entry). All four
sources (grub.cfg + live.cfg.in templates, build.sh write_canonical_*) match.
The internal GSP auto-fallback in bee-nvidia-load (normal mode, GSP init
hangs >90s → retry with EnableGpuFirmware=0, then still load uvm) is left
intact — it serves converted SXM->PCIe cards on other test targets and keeps
CUDA working, unlike the removed explicit menu mode.

no-GUI is now just the normal entry minus the GUI: bee.gui=off with
bee.nvidia.mode=normal (drops the previous gsp-off/pci=realloc it had picked
up). fail-safe is now simply the GPU/PCIe-workaround boot —
bee.nvidia.mode=gsp-off pci=realloc iommu=pt over the standard base — instead
of the old noapic/nodma/nomce/nolapic/nosmp minimal mode, so it can actually
run GPU tests (nvbandwidth) to verify the iommu=pt half of the vendor fix.
Applied identically across all four sources (grub.cfg + live.cfg.in templates
and build.sh write_canonical_* generators).

The GRUB and isolinux menus (and their two sources of truth — the staged
templates and build.sh's write_canonical_* generators that rewrite the built
menu) had drifted: GRUB shipped a lean set, isolinux carried extra
display-debug entries (gsp-off, kms, kms-gsp-off) and lacked a WIPE entry in
the canonical writer. Collapse all four to one set:
normal, load-to-RAM (default), no-GUI/troubleshooting (gsp-off, pci=realloc),
fail-safe, WIPE ALL DISKS, Memory Test, + UEFI Firmware Settings (EFI only)
The fail-safe entry gains iommu=pt (AMD-Vi passthrough) — the OS-side half of
the vendor fix for the MSI CG480-S6053 cross-socket nvbandwidth reboot; ACS
can't be toggled from a stock-kernel cmdline so that stays a BIOS setting.
default stays index 1 = toram (config.cfg set default=1).

pci=realloc was forcing a full PCI resource reallocation on every default
and toram boot, added as a GPU BAR workaround for BIOS without Above 4G
Decoding. On a dense NVMe-backplane server it exhausted MMIO32 space and
silently dropped 4 of 6 NVMe controllers from the OS even though the BIOS
and lspci both saw them fine. It now only applies to the no-GUI/gsp-off
troubleshooting entry, alongside a bible-local ADR for the two prior
rounds of SAT/blackbox durability work.

Adds a "WIPE ALL DISKS" entry to both GRUB and isolinux menus (bee.wipe=all).
Includes bee-wipe-disks for manual use from a running live system.

GRUB's PNG reader (grub2 bookworm) fails to load bee-logo.png despite the
file being valid RGB 8-bit non-interlaced PNG with minimal chunks. Root
cause is a known fragility in GRUB's png.c; exact trigger is unknown.
Switch to uncompressed 24-bit TGA which bypasses the PNG parser entirely.
tga.mod is already present in the ISO (x86_64-efi/tga.mod).
- Convert bee-logo.png → bee-logo.tga (480018 bytes, BGR top-left)
- config.cfg: insmod png → insmod tga
- theme.txt: bee-logo.png → bee-logo.tga
- Document all prior failed attempts in git-bible/grub-bitmap-error.md

GRUB does not support RGBA PNG (color_type=6) — loading it returns a
null bitmap, triggering "null src bitmap in grub_video_bitmap_create_scaled".
Alpha channel composited onto black background (#000000 matches desktop-color).

- Convert bee-logo.png to RGBA (color type 6) and strip all metadata
chunks (cHRM, bKGD, tIME, tEXt) that confuse GRUB's minimal PNG parser
- Move terminal_output gfxterm before insmod png / theme load so the
theme initialises in an active gfxterm context
- Remove echo ASCII art banner from grub.cfg — with gfxterm active and
no terminal_box in the theme, echo output renders over the menu area
- Fix icon_heigh typo → icon_height; increase item_height 16→20 with
item_padding 0→2 for reliable text rendering in boot_menu

Default and toram entries now boot with bee.display=kms (ASPEED AST
loads via KMS, Xorg uses modesetting driver) and pci=realloc (Linux
reassigns GPU BARs when BIOS lacks Above 4G Decoding). nomodeset
removed from these entries; still present in GSP=off and fail-safe.

Em-dash (U+2014) renders as garbage on GRUB serial/SOL output
(IPMI BMC consoles). Replace with ASCII double-hyphen throughout
grub.cfg template, write_canonical_grub_cfg, and theme.txt comment.
Also align template grub.cfg structure with write_canonical_grub_cfg:
toram entry moved to top level (was inside submenu).
bible: add ascii-safe-text contract documenting the no-em-dash rule.

Stability hardening (webui/app):
- readFileLimited(): защита от OOM при чтении audit JSON (100 MB),
component-status DB (10 MB) и лога задачи (50 MB)
- jobs.go: буферизованный лог задачи — один открытый fd на задачу
вместо open/write/close на каждую строку (устраняет тысячи syscall/сек
при GPU стресс-тестах)
- stability.go: экспоненциальный backoff в goRecoverLoop (2s→4s→…→60s),
сброс при успешном прогоне >30s, счётчик перезапусков в slog
- kill_workers.go: таймаут 5s на скан /proc, warn при срабатывании
- bee-web.service: MemoryMax=3G — OOM killer защищён
Build script:
- build.sh: удалён блок генерации grub-pc/grub.cfg + live.cfg.in —
мёртвый код с v8.25; grub-pc игнорируется live-build, а генерируемый
live.cfg.in перезаписывал правильный статический файл устаревшей
версией без tuning-параметров ядра и пунктов gsp-off/kms+gsp-off
- build.sh: dump_memtest_debug теперь логирует grub-efi/grub.cfg
вместо grub-pc/grub.cfg (было всегда "missing")
GRUB:
- live-theme/bee-logo.png: логотип пчелы 400×400px на чёрном фоне
- live-theme/theme.txt: + image компонент по центру в верхней трети
экрана; меню сдвинуто с 62% до 65%

grub-efi/grub.cfg: add KMS+GSP=off entry (was in isolinux, missing in GRUB)
isolinux/live.cfg.in: add full standard param set to all entries
(net.ifnames=0 biosdevname=0 mitigations=off transparent_hugepage=always
numa_balancing=disable nowatchdog nosoftlockup) to match grub-efi
bible-local/docs/iso-build-rules.md: add bootloader sync rule documenting
that grub-efi and isolinux must be kept in sync manually, listing canonical
entries and standard param set, and noting the grub-pc/grub-efi history.

Build uses --bootloaders "grub-efi,syslinux" so live-build reads
config/bootloaders/grub-efi/ for the UEFI GRUB config. The directory
was incorrectly named grub-pc, causing live-build to ignore our custom
grub.cfg and generate a default one (missing toram, GSP-off entries).
