Writing to /sys/class/scsi_host/hostX/scan on SAS controllers (e.g.
Adaptec smartpqi/PM8222-SHBA) triggers sas_user_scan which blocks
indefinitely, causing the audit to hang forever. Skip hosts that appear
under /sys/class/sas_host/ — SAS topology is discovered by the driver.

- storage: add jsonInt64 dual-format unmarshaler to handle lsblk output
change in util-linux 2.38 (LOG-SEC/PHY-SEC now emitted as JSON
integers, not quoted strings); fixes SATA disks invisible on Debian 12
- pcie: detect NVLink bridge mezzanine CX-7 cards (Mellanox x2, no host
net ifaces, DeviceName contains "NVLINK" in lspci -v) and mark them
with device_class="NVLinkBridge"; escalate PCIe link speed downgrade to
Critical for these cards (Gen3 on a fixed internal connector = hardware
fault, not a transient warning)
- pcie: cross-reference nvidia-smi topo to capture NVLink bond counts and
active status for all NVLink bridge cards
- packages: add infiniband-diags to ISO; provides ibstat required by
nvidia-fabricmanager-start.sh to enumerate IB devices before FM launch
(absence causes CUDA_ERROR_SYSTEM_NOT_READY)

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.

Add nvidia-aer-correctable and pcie-aer-correctable patterns to catch
"bus correctable error" events seen in SEL (Critical Interrupt / offset 7).
Both patterns carry severity "warning" — correctable errors are
hardware-recovered and should not flag a card as failed.
Fix kmsg_watcher routing: GPU-category events were keyed as pcie:<BDF>
but the UI queries for pcie:gpu: prefix. Split the switch so "gpu" →
pcie:gpu:<BDF> and "pcie" → pcie:<BDF>. This applies to both
flushWindow (SAT-window path) and flushImmediate (always-on path).

HTMX was never loaded on the page, so hx-get on the component label
spans was dead code — the dialog opened empty. Replace with a plain
openComponentDetail() fetch call. Also fix dialog positioning broken
by the CSS reset (*{margin:0} overrode the UA margin:auto that centers
<dialog>). Replace card hx-trigger polling with a setInterval.

- kmsg watcher now records kernel errors (GPU Xid, MCE, EDAC, storage I/O) at all times,
not only during SAT tasks; flushImmediate writes directly to ComponentStatusDB
- New health_poller: polls ipmitool sdr every 60s for PSU health (watchdog:psu source)
- Hardware Summary card auto-refreshes every 30s via htmx without page reload
- Component rows (CPU/Memory/Storage/GPU/PSU) are now clickable -- opens a modal
with per-component status, source, timestamp and last 20 history entries

IPMI hang fix (Lenovo XCC SR650 V3):
- Add pluggable ipmi_profile system with per-vendor timeouts and fruEarlyExit flag
- Lenovo profile: 90s FRU timeout, streaming early-exit stops after PSU blocks found
- collectFRUEarlyExit streams ipmitool fru print and kills process once PSU blocks
are followed by a non-PSU header (~6s instead of ~108s on 54-device FRU list)
- collectBMCFirmware and collectPSUs accept manufacturer and apply profile timeouts
VROC license detection:
- Detect VMD/VROC controller in PCIe list, run mdadm --detail-platform
- Parse "License:" line; store as snap.VROCLicense in HardwareSnapshot
Blackbox service fix:
- bee-blackbox.service was missing from systemctl enable list in ISO build hook
- Service never started on boot; state file never written; UI button stayed "Enable"
Drop qrencode:
- Remove from package list, standardTools API check, and runtime-flows doc

targeted_stress, targeted_power, and the Level 2/3 diag were dispatched
one GPU at a time from the UI, turning a single dcgmi command into 8
sequential ~350–450 s runs. DCGM supports -i with a comma-separated list
of GPU indices and runs the diagnostic on all of them in parallel.
Move nvidia, nvidia-targeted-stress, nvidia-targeted-power into
nvidiaAllGPUTargets so expandSATTarget passes all selected indices in one
API call. Simplify runNvidiaValidateSet to match runNvidiaFabricValidate.
Update sat.go constants and page_validate.go estimates to reflect all-GPU
simultaneous execution (remove n× multiplier from total time estimates).
Stress test on 8-GPU system: ~5.3 h → ~2.5 h.

DCMI reports only the managed power domain (~CPU+MB), missing GPU draw.
PSU AC input sensors cover full wall power. When samplePSUPower returns
data, sum the slots for PowerW; fall back to DCMI otherwise.

\b does not fire between a digit and '_' because '_' is \w in RE2.
The pattern \bpsu?\s*([0-9]+)\b never matched PSU1_POWER_IN style
sensors, so parsePSUSDR (and PSUSlotsFromSDR / samplePSUPower) returned
empty results for MSI servers — causing all power graphs to fall back
to DCMI which reports ~half actual draw.
Added an explicit underscore-terminated pattern first in the list and
tests covering the MSI format.

Same fix as ramp steps: take sdrSingle snapshot after calibration
and prefer PSUInW over DCMI for singleIPMILoadedW. DCMI kept as
fallback. Log message indicates source.

When sdrStep.PSUInW is available, prefer it over DCMI for
ramp.ServerLoadedW and ServerDeltaW. DCMI on this platform (MSI 4-PSU)
reports ~half actual draw; SDR sums all PSU_POWER_IN sensors correctly.
Delta is now SDR-to-SDR (sdrStep.PSUInW - sdrIdle.PSUInW) for
consistency. DCMI path kept as fallback when SDR has no PSU data.
Log message now indicates the source (SDR PSU AC input vs DCMI).

MSI servers place PSU_POWER_IN/OUT sensors on entity 3.0, not 10.N
(the IPMI "Power Supply" entity). The old parser filtered by entity ID
and found nothing, so the dashboard fell back to DCMI which reports
roughly half the actual draw.
Now delegates to collector.PSUSlotsFromSDR — the same name-based
matching already used in the Power Fit benchmark.

A single dcgmproftester process without -i only loads GPU 0 regardless of
CUDA_VISIBLE_DEVICES. Now always routes multi-GPU runs through
bee-dcgmproftester-staggered (--stagger-seconds 0 for parallel mode),
which spawns one process per GPU so all GPUs are loaded simultaneously.

- Increase stability profile duration from 33 min to 90 min by wiring
powerBenchDurationSec() into runBenchmarkPowerCalibration (was discarded)
- Collect per-step PSU slot readings, fan RPM/duty, and per-GPU telemetry
in ramp loop; add matching fields to NvidiaPowerBenchStep/NvidiaPowerBenchGPU
- Rewrite renderPowerBenchReport: replace Per-Slot Results with Single GPU
section, rework Ramp Sequence rows=runs/cols=GPUs, add PSU Performance
section (conditional on IPMI data), add transposed Single vs All-GPU
comparison table in per-GPU sections
- Add fmtMDTable helper (benchmark_table.go) and apply to all tables in
both power and performance reports so columns align in plain-text view

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%

As metrics.db grew (1 sample/5 s × hours), handleMetricsChartSVG called
LoadAll() on every chart request — loading all rows across 4 tables through a
single SQLite connection. With ~10 charts auto-refreshing in parallel, requests
queued behind each other, saturating the connection pool and pegging a CPU core.
Fix: add a background compactor that runs every hour via the metrics collector:
• Downsample: rows older than 2 h are thinned to 1 per minute (keep MIN(ts)
per ts/60 bucket) — retains chart shape while cutting row count by ~92 %.
• Prune: rows older than 48 h are deleted entirely.
• After prune: WAL checkpoint/truncate to release disk space.
LoadAll() in handleMetricsChartSVG is unchanged — it now stays fast because
the DB is kept small rather than capping the query window.

Snapshot IPMI "Power Supply" sensor states before and after each benchmark
run. Compare before/after to surface only *new* anomalies (pre-existing faults
are excluded). Results land in NvidiaBenchmarkResult.PSUIssues and
NvidiaPowerBenchResult.PSUIssues (JSON: psu_issues) and are printed in the
text benchmark report under a "PSU Issues" section.

- TestHandleAPIBenchmarkPowerFitRampQueuesBenchmarkPowerFitTasks: ramp-up
mode intentionally creates a single task (the runner handles 1→N internally
to avoid redundant repetition of earlier ramp steps). Updated the test to
expect 1 task and verify RampTotal=3 instead of asserting 3 separate tasks.
- TestBenchmarkPageRendersSavedResultsTable: benchmark page used "Performance
Results" as heading while the test looked for "Perf Results". Aligned the
page heading with the shorter label used everywhere else (task reports, etc.).
