Extract the fan peak-tracking into observedPeakStore (observe max under
load, hold >= minHold to reject spikes, round, persist JSON) and add a
second instance for PSU draw (psu-observation.json, keyed by PSU
ordinal). Fed from samplePSUPower like fans are from sampleFanSpeeds, so
any full-load run refines it — the Fan Ceiling Check (which also samples
PSU power at a slow cadence off its loop and writes psu_<i>_peak_w), a
burn, thermal cycling, and the 5s web metrics collector.
/topo PSU cards now scale the load fill by wattage_w when the BMC
reports it, else by the observed peak draw — marked "~N% load". This
MSI stand's BMC gives only instantaneous input power, so the observed
peak is the only capacity figure available.
Fan behaviour is unchanged (tests exercise updateFanObservation /
estimateFanDutyCyclePctFromObservation / ResolveFanMaxRPM through the
new store).

- GPU load switches from bee-gpu-burn (compute burn, ~88% TDP) to
dcgmproftester -t 1004 / targeted_power via
resolveBenchmarkPowerLoadCommand — the same engine Power/Thermal Fit
uses and the hottest sustained NVIDIA load we have, so fans are
actually pushed toward their ceiling.
- Sample loop is now IPMI-hang-proof: every ipmitool read is time-boxed
in an abandonable goroutine, and the poll interval backs off
geometrically (1s→30s) when reads are slow, tightening again on
recovery. A plateau is only trusted while telemetry is healthy;
degraded runs ride out to MaxLoadSec. Summary gains fan_samples /
telemetry_degraded. Drops the per-second nvidia-smi+power+cpu-temp
sampling from the hot loop.
- Dead code removed: FanStressRow, GPUStressMetric, sampleFanStressRow,
sampleGPUStressMetrics, WriteFanStressCSV/WriteFanSensorsCSV,
analyzeMaxTemp, sampleSystemPowerResolved.
Topology fan tiles:
- size encodes the fan's ceiling RPM (its class), not current speed;
coloured fill rising from the bottom encodes live duty cycle
(current / ceiling), shown only when the ceiling was measured.
- glyph spin rate now maps absolute RPM into a human-perceptible band
(fanSpinPeriodSec: 2.2s/turn at <=1000 RPM, 0.35s at >=13000).
- the "N fans · N OK · tile size ∝ …" caption line is gone.

Repurpose the previously-unwired RunFanStressTest into RunFanCheck, a
Load-tier SAT test that drives stressapptest (CPU+memory) and, when a GPU
is present, a GPU burn to 100% simultaneously, then watches every fan
until none has climbed for ~60s. The observed peak RPM per fan is the
"ceiling"; it is persisted through the existing fan-observation store.
MSI G4201 / AMI MegaRAC exposes no host-side fan force (every OEM IPMI
command returns 0xc1; Redfish Thermal is GET-only), so load-driven ramp
is the closest safe equivalent. See
bible-local/decisions/2026-09-04-fan-ceiling-check.md.
- platform.ResolveFanMaxRPM: per-fan max with fallback (persisted peak ->
peer peak -> current RPM), resolved in platform, not the view.
- platform.ErrTestNotApplicable: no load source or no fan sensors ->
task lands as cancelled ("not applicable"), never failed, so an
engineer never sees a false red. executeTaskWithOptions maps the
sentinel; finalizeTaskForResult honours a pre-set TaskCancelled.
- Verdict FAIL only for a fan at 0 RPM / IPMI cr-nr under load.
- /topo: one small spinning square per fan, sized by RPM / resolved max,
clickable through to a new "fan" component-detail type; per-fan status
recorded to the component-status DB from the fan SAT summary.
- Wiring: /api/sat/fan/run route, "fan" task target, Load-page card,
stress-mode Run All.

Every GPU-selection picker (Load/SAT, Burn, Benchmark) now renders the
card serial: "GPU N — <model> · <mem> MiB · sn: <serial>". The serial is
monospace and the digits that differ across the listed GPUs (common
prefix/suffix stripped) are emphasised so operators can tell cards apart.
Row markup was duplicated across three pages (and twice within
page_validate.go). Consolidated into a single module,
internal/webui/gpu_picker.go: beeGpuPicker.render({...}) builds every row;
gpuPickerCSS/gpuPickerJS are injected once by layoutHead/renderPage. Pages
keep their own selection-note text and multi-GPU toggles but no longer
hand-build <label> markup.
ListNvidiaGPUs() adds the serial via nvidia-smi --query-gpu=...,serial;
N/A is normalised to empty. Serial flows to the client unchanged through
the existing /api/gpu/nvidia JSON response.

NVIDIA GPUs deliberately downclock PCIe to Gen1 at idle for power
saving, and applyPCIeLinkSpeedWarning fired on every idle collector
pass regardless - since component-status DB records never downgrade
(Record() only ever raises severity), one boot-time idle sample
permanently pinned pcie:gpu:nvidia to Warning for the rest of the
session even after every load-bearing GPU SAT test passed clean. Two
prior fixes (nvidia-smi-sourced link speed, pcie_aspm=off boot flag)
didn't hold up against this hardware/driver combination - see
bible-local/decisions/2026-08-24-pcie-gpu-gen1-idle-warning.md for the
full history.
Rather than add a downgrade path, stop writing an unverified status in
the first place: parseLspciDevice no longer calls
applyPCIeLinkSpeedWarning on the idle path. LinkSpeed/MaxLinkSpeed stay
populated as plain descriptive fields; only a verified-under-load
caller may now turn them into a status verdict.
Two new SAT targets provide that verified signal:
- pcie-link (platform/pcie_link_check.go): forces every enabled PCIe
device - not just GPUs - to retrain via the PCIe spec's Link Control
"Retrain Link" bit, then compares the negotiated speed against the
device's max. Covers NICs/HBAs/switches that have no bee-gpu-burn
equivalent load tool. Classifies by PCI class code + vendor ID, not
name substrings. Routes gpu_nvidia/gpu_amd/other sub-verdicts into
their own component-status keys so a degraded NIC never reads as a
GPU fault.
- nvidia-pcie-bandwidth (platform/nvidia_pcie_bandwidth.go): drives
real host<->device traffic via dcgmi diag -r nvbandwidth and
resamples link speed immediately after, independent of nvbandwidth's
own pass/fail.
Both wired into the task queue/webui the same way as nvidia-config
(routes, dispatch, priority, Validate page cards, Run All Check SAT).

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.

nvidia-smi exposes reset_status.reset_required and remapped_rows.* only on
newer drivers for Ampere+ GPUs; queried via a separate exec call since an
unrecognized field name fails the whole --query-gpu command and would have
wiped out unrelated telemetry (temp/ECC/power) on older drivers otherwise.
Also refines Xid severity in both the ingest dmesg collector and the
always-on kmsg watcher: Xid 64 (row-remap InfoROM write failure) now
escalates to Critical instead of the generic warning every other Xid got,
and fixes the SAT-window flush path which previously hardcoded "Warning"
and ignored pattern severity entirely.

HardwareSnapshot.
B (no-hardcoded-vendors): consolidate PCI vendor IDs into collector/pci_vendors.go;
replace all vendor-name string checks in isGPUDevice, isNVIDIADevice, isMellanoxDevice,
isAMDGPUDevice, matchesGPUVendor (sat_overlay), and validateIsVendorGPU (page_validate)
with numeric vendor_id comparisons.
C (module-structure): split app/app.go (1413 lines) into app.go + app_format.go,
app_network.go, app_services.go, app_packs.go, app_install.go — no logic changes.
D (go-code-style): wrap bare return err in interfaceAdminState and
interfaceIPv4Addrs (platform/network.go) with fmt.Errorf context including
the interface name.

Disabled PCIe devices (sysfs enable==0) carry no data traffic; their
link state has no operational impact. Switchtec PCIe switch management
endpoints on NVIDIA HGX H100 baseboards (and similar fabric controllers)
train at reduced speed intentionally and were producing spurious warnings.
Check is vendor-agnostic: reads enable attribute via existing helper,
no vendor/device ID hardcoding.
Documented in bible-local/decisions/2026-06-12-pcie-disabled-device-link-warning.md.

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:

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

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%
