The NVSwitch-detection fix (983f41a) was necessary but not sufficient on
HGX B200 (Kaytus KR9288-X3): ExecCondition now correctly runs fabricmanager,
but nvidia-fabricmanager-start.sh then aborts with "Kernel module ib_umad
has not been loaded" on this NVL5+ board, leaving the fabric stuck in
"In Progress" and cascading into failed dcgmi diag/NVBandwidth/NCCL/Validate
GPU SAT tasks (confirmed via support bundle 20260729-165331).
Neither nvidia-fabricmanager nor DCGM declare the NVLink5 support packages
as apt dependencies (checked against the cuda-repo Packages index directly):
ib_umad must be modprobed before FM starts, nvlsm (InfiniBand Subnet Manager)
is launched internally by FM's own start script once present, and DCGM
dlopens libnvidia-nscq at runtime for NVSwitch health monitoring.

On HGX B200 (Kaytus KR9288-X3) NVSwitch is managed via HMC/ERoT and never
appears on host lspci as 10de:0680, so the old check always returned
"not present" and silently skipped fabricmanager — leaving the fabric
untrained and CUDA/NCCL/dcgmi failing with "system not yet initialized"
on otherwise-healthy hardware. bee-check-nvswitch now checks, in order,
nvidia-smi's GPU Fabric GUID, /proc/driver/nvidia-nvswitch/devices, and
finally the legacy host-PCIe scan for older HGX generations.
- page_scenario.go: onclick built via JSON.stringify() embedded raw double
quotes inside a double-quoted HTML attribute, truncating the attribute so
the click handler never compiled; pass the name through an escaped
data-scenario-name attribute instead.
- build.sh: overlay staging rsyncs (OVERLAY_DIR->stage, stage->includes.chroot)
ran without --delete, so a scenario removed from the repo (a9924b0) stayed
baked into every ISO built from the persistent stage cache since — the
"second script" in the Scenario page's list.
- blackbox: rewritten around a deterministic local zip + incremental
patch-the-changed-suffix onto removable media, instead of walking/copying
~90 files through a synchronous ntfs-3g FUSE mount every cycle. journalctl
captures are now "--since last sync" (were "--since boot", growing with
uptime) and metrics.db is excluded (was copied whole every cycle).
- scenario: nvbandwidth-acs-ab now escalates GPU count (same-socket pair,
other socket's pair, one cross-socket pair, all GPUs) under each ACS state
instead of always running all 6 GPUs at once, using a new `bee
gpu-bandwidth-groups` subcommand that discovers socket layout from
`nvidia-smi topo -m` at runtime — gpu_indices is host-specific, so this
can't be baked into the scenario file.

Replaces the old nvbandwidth-all-gpu-power-watch scenario (dropped: the
power/IPMI-sampler framing was a dead-end — the blackbox shows every other
load test, incl. NCCL all-reduce across all 6 GPUs, passes with power fully
connected; only nvbandwidth on cross-socket GPU P2P reboots the box).
nvbandwidth-acs-ab is a two-phase reproduction for the MSI CG480-S6053 case.
Phase 1 disables PCIe ACS redirect at runtime via setpci (saving each
bridge's original ACS control word to /run/bee-acs-orig) then runs
nvbandwidth across all 6 GPUs — expected to survive. Phase 2 restores the
saved ACS values and repeats — expected to reproduce the reboot. Safe phase
first so its full blackbox reaches the USB stick before the risky phase can
reset the box (sync-bracket before the final job flushes phase-1 evidence).
ACS mutation runs via `bash -c` since scenario cmd is exec'd directly with no
shell. Both shipped copies (repo scenarios/ and image overlay) identical;
verified both parse via ParseScenarioJSON (4 jobs).

ScenarioSpec gains an optional "description" field. Listing (both
ListLocalScenarioFiles and ListScenarioFilesOnRemovableMedia, via the new
scenarioDescription helper) reads it out of each file without requiring
full ParseScenarioJSON validation to succeed, so a listing never hides a
scenario over an unrelated validation issue. The webui Scenario page now
renders Name/Description/Found-on/Run instead of just Name/Found-on — a
bare filename rarely tells anyone but the author what a scenario actually
does.

platform.LocalScenariosDir (/usr/share/bee/scenarios, populated from
iso/overlay/usr/share/bee/scenarios/ by build.sh's overlay rsync) is now
checked before removable media for both `bee run <name>` and the "6.
Scenario" page — a scenario shipped with the image works with no USB
stick required. ReadScenario/ListAvailableScenarios merge local + USB;
the removable-media-only functions from the previous commit are kept
as-is (still used directly where that's actually what's wanted) rather
than renamed out from under existing callers/tests.
iso/overlay/usr/share/bee/scenarios/nvbandwidth-all-gpu-power-watch.json
is a copy of scenarios/nvbandwidth-all-gpu-power-watch.json — the two
aren't auto-synced (documented in scenarios/README.md), so shipping a
scenario baked-in means checking it into both places.

dcgmi discovery -l is a preflight/metadata step ahead of the real DCGM
diag jobs; a transient failure racing nv-hostengine startup shouldn't
flip the whole pack's status, so it's now marked informational with a
couple of retries. Separately, bound the fabricmanager/nvidia-dcgm
systemctl restart/start calls in bee-nvidia-load with a timeout so a
wedged unit (e.g. fabric training stuck on a bad NVSwitch fabric)
can't hang bee-nvidia.service forever and block dcgm from ever
starting.

Add NVLink port status (nvidia-smi nvlink -s), error counters
(nvidia-smi nvlink -e), and dcgmi nvlink status to the support bundle,
and enrich HardwarePCIeDevice entries with per-link telemetry.
Replace the raw nv-hostengine pkill/restart dance in bee-nvidia-load
with systemctl restart/start of nvidia-dcgm.service, and order
bee-nvidia.service Before= nvidia-dcgm.service and
nvidia-fabricmanager.service so modules/device nodes exist before
those units start.
- sat.go: DetectGPUVendor lspci fallback now checks GPU device classes
([0300]/[0302]/[0380]) per line instead of scanning the whole output for
vendor name; AMD EPYC servers have dozens of AMD-branded PCIe entries
(Root Complex, IOMMU, Host Bridge) that were triggering the old check
- blackbox.go: fix deadlock in finishCycle — it held w.mu while calling
persistState(), which acquires rt.mu then re-acquires w.mu inside
persistStateLocked(); now w.mu is released before persistState()
- build.sh: remove NVIDIA-specific overlay files (bee-gpu-burn,
bee-john-gpu-stress, bee-nccl-gpu-stress, bee-nvidia-recover,
bee-dcgmproftester-staggered, bee-check-nvswitch,
nvidia-fabricmanager.service.d/) for non-nvidia build variants
- bee-selfheal: gate NVIDIA recovery on BEE_GPU_VENDOR=nvidia so the
script does not attempt to restart bee-nvidia.service on NOGPU builds

bee-nvidia.service loads NVIDIA kernel modules; without After=bee-nvidia.service
fabricmanager starts before /dev/nvidiactl is ready, fails, and relies on
systemd restart to recover (~38s delay on affected systems).

Network: green if at least one interface has IPv4 (drop PARTIAL state).
Bee Services: treat inactive as OK — oneshot services (bee-sshsetup,
bee-preflight, bee-network, bee-audit, etc.) complete successfully and
exit to inactive; only failed is a real problem.
nvidia-fabricmanager: add ExecCondition=bee-check-nvswitch drop-in so
the service is silently skipped (inactive, not failed) on systems
without NVSwitch hardware (e.g. H200 NVL with direct NVLink, no
NVSwitch chips). bee-check-nvswitch detects NVSwitch via lspci
(vendor 10de, class 0680).
bee-nvidia.service: add ConditionPathExists=/usr/local/bin/bee-nvidia-load
so the unit is a no-op if somehow present in a non-nvidia build.
bee-boot-status: read /etc/bee-gpu-vendor and exclude bee-nvidia from
CRITICAL/ALL on non-nvidia builds, preventing boot hang if the unit
is unexpectedly present.

Installs a local-premount initramfs hook that intercepts bee.wipe=all before
squashfs is mounted. Shows a numbered disk selection TUI (pure POSIX sh), wipes
selected disks (nvme format / blkdiscard / dd fallback), syncs, and reboots.
Works even when squashfs fails to mount.

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.

dcgmproftester and other GPU test subprocesses run inside the bee-web
cgroup and exceed 3G with 8 GPUs. OOM killer terminates the whole
service. No memory cap is appropriate on a LiveCD where GPU tests
legitimately use several GB.

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.cfg: add "load to RAM (toram)" entry to advanced submenu
- install_to_ram.go: resume from existing /dev/shm/bee-live copy if
source medium is unavailable after bee-web restart
- tasks.go: fix "Recovered after bee-web restart" shown on every run
(check j.lines before first append, not after)
- bee-install: retry unsquashfs up to 5x with wait-for-remount on
source loss; clear error message with bee-remount-medium hint
- bee-remount-medium: new script to find and remount live ISO source
after USB/CD reconnect; supports --wait polling mode
- 9000-bee-setup: chmod +x for bee-install and bee-remount-medium

- grub.cfg + isolinux/live.cfg.in: add pcie_aspm=off,
intel_idle.max_cstate=1 and processor.max_cstate=1 to all
non-failsafe boot entries
- bee-hpc-tuning: new script that sets all CPU cores to performance
governor via sysfs and logs THP state at boot
- bee-hpc-tuning.service: runs before bee-nvidia and bee-audit
- 9000-bee-setup.hook.chroot: enable service and mark script executable

HPL 2.3 from netlib compiled against OpenBLAS with a minimal
single-process MPI stub — no MPI package required in the ISO.
Matrix size is auto-sized to 80% of total RAM at runtime.
Build:
- VERSIONS: HPL_VERSION=2.3, HPL_SHA256=32c5c17d…
- build-hpl.sh: downloads HPL + OpenBLAS from Debian 12 repo,
compiles xhpl with a self-contained mpi_stub.c
- build.sh: step 80-hpl, injects xhpl + libopenblas into overlay
Runtime:
- bee-hpl: generates HPL.dat (N auto from /proc/meminfo, NB=256,
P=1 Q=1), runs xhpl, prints standard WR... Gflops output
- platform/hpl.go: RunHPL(), parses WR line → GFlops + PASSED/FAILED
- tasks.go: target "hpl"
- pages.go: LINPACK (HPL) card in validate/stress grid (stress-only)

- bee-nvidia-load: run insmod in background, poll /proc/devices for
nvidiactl; if GSP init doesn't complete in 90s, kill insmod and retry
with NVreg_EnableGpuFirmware=0. Handles EBUSY case with clear error.
- Write /run/bee-nvidia-mode (gsp-on/gsp-off/gsp-stuck) for audit layer
- Show GSP mode badge in sidebar: yellow for gsp-off, red for gsp-stuck
- Report NvidiaGSPMode in RuntimeHealth with issue entries
- Simplify GRUB menu: default (KMS+GSP), advanced submenu (GSP=off,
nomodeset, fail-safe), remove load-to-RAM entry
- Add pcmanfm, ristretto, mupdf, mousepad to desktop packages

- Add feh and python3-pil to package list
- Add chroot hook that generates /usr/share/bee/wallpaper.png using PIL:
black background, EASY-BEE box-drawing logo in amber (#f6c90e),
"Hardware Audit LiveCD" subtitle in dim amber — matches motd exactly
- bee-openbox-session: set wallpaper with feh --bg-fill, fall back to
xsetroot -solid black if wallpaper not found

- Set xsetroot solid background (#12100a, dark amber) so openbox

- Re-add healthz wait loop before launching Chromium: without it
Chromium opens localhost/loading before bee-web is up and gets
connection-refused which renders as a blank white page

Add TTYReset=yes and TTYVHangup=yes so systemd restores the terminal

Also remove DefaultDependencies=no which was too aggressive.

- Refresh every 3s instead of 1s to reduce flicker
- Show ssh, bee-sshsetup in service list
- Show failure reason for failed services
- Show last journal line for activating services
- Show IP addresses and web UI URL when network is up
- Render frame to variable before printing to reduce flicker
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Add bee-boot-status service: shows live service status on tty1 with
ASCII logo before getty, exits when all bee services settle
- Remove lightdm dependency on bee-preflight so GUI starts immediately
without waiting for NVIDIA driver load
- Replace Chromium blank-page problem with /loading spinner page that
polls /api/services and auto-redirects when services are ready; add
"Open app now" override button; use fresh --user-data-dir=/tmp/bee-chrome
- Unify branding: add "Hardware Audit LiveCD" subtitle to GRUB menu,
bee-boot-status (with yellow ASCII logo), and web spinner
