The passive collector records PSU draw at idle too, so right after boot
the "observed peak" is just idle wattage and a load % off it is
meaningless. Require the observed peak to sit >=25% above current draw
before using it as a load scale; until a real full-load run bumps it,
show plain watts.

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).

Same idea as the fan duty-cycle fill: a bar rising from the bottom of
each PSU card for draw / nameplate rating, live-updated on the shared
5s /api/metrics/latest poll. Drawn only when the rating (wattage_w) is
known — a raw wattage with nothing to scale against is not a load
figure, so BMCs that report only input power (e.g. this MSI stand) keep
showing the plain watts. Detail line becomes "<v> V · <draw> / <rating> W
· <n>% load" when both are present.

Each PSU is its own card, coloured by its own status — a failed unit
goes red on its own instead of dragging a single grouped card down —
and shows input voltage + draw (measured output/input, else nameplate
rating). Cards click through to the PSU detail modal and carry data-psu
so the shared topoLiveScript refreshes their wattage from
/api/metrics/latest on the same 5s poll as the fan tiles.

Each fan tile carries data-fan / data-ceil / data-measured and a small
script polls /api/metrics/latest every 5s — the metrics collector's own
sampling period, served from memory with no extra BMC call — updating
each tile's spin rate, duty fill and tooltip in place. Polling faster
would only re-read identical numbers; sampling the BMC faster would
choke it under load. FanReading gains json tags for the endpoint.

It is a platform cooling test (CPU + memory always; GPU only as extra

- 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.

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.

Every sample was stamped with time.Now(), so a timezone switch or NTP
step punched a multi-hour gap into the series: old points collapsed to
the left edge, new points bunched at the right, joined by one diagonal.
Stamp rows from a monotonic seqClock instead — seeded once from the wall
clock (or the newest persisted row) and thereafter advanced only by the
monotonic elapsed time between writes. Rebase Downsample/Prune on the
newest sample rather than time.Now() so a clock step just before the
hourly compaction can't drop fresh data.

The NVIDIA GSP firmware was staged into the overlay at a bare
lib/firmware/nvidia/<ver>/. On a merged-usr Debian root /lib is a symlink
to usr/lib, so the fast-path repack's `rsync -a` (overlay stage -> the
unsquashfs'd tree) replaced that symlink with a plain directory holding
only the firmware. Everything else reachable only through /lib
(/lib/systemd/systemd, /lib/x86_64-linux-gnu/ld-linux + libc, ...) was
orphaned. The squashfs still packed and mounted, but boot panicked:
run-init: can't execute '/sbin/init': No such file or directory
run-init: can't execute '/bin/sh': No such file or directory
Kernel panic - not syncing: Attempted to kill init
Full `lb build` was unaffected (live-build copies includes.chroot with
cp -a, which follows the /lib symlink), so only fast-path ISOs were bad.
Three fixes:
- build.sh: stage GSP firmware under usr/lib/firmware/nvidia/<ver>/, the
canonical merged-usr path. Changing the overlay path also makes
overlay_paths_were_removed() force one full build on the next run.
- fast-path.sh: add `rsync --keep-dirlinks` so a real directory in the
overlay stage can never again replace a symlink-to-directory in the
root. Verified: firmware lands in usr/lib/firmware, /lib stays a symlink.
- iso-validation.sh: new validate_iso_rootfs_layout, run for every variant
on both build paths. Fails the build if the squashfs has a plain-dir
/bin|/sbin|/lib|/lib64, or if /usr/sbin/init is present without a
resolvable /usr/lib/systemd/systemd and /lib symlink. Verified it flags
the broken v14.02-1-g642e686 ISO and passes a correct layout.

On hosts where the boot medium is BMC/IPMI virtual media, the ~2.8 GB
squashfs read often drops mid-transfer: rsync dies with "Input/output
error (5)", every file "has vanished", and live-boot moves the partial
RAM copy over the medium, ending the boot with "No supported filesystem
images found at /live".
Add hook 9013-toram-retry, which patches live-boot's 9990-toram-todisk.sh
so the whole-medium copy runs in a retry loop: up to 8 attempts with a
geometrically growing pause (15s -> 900s cap), unmounting/waiting/remounting
the medium between tries and honouring rsync's exit code (upstream ignores
it). rsync resumes from where it stopped, so a retry needing only the tail
finishes fast.
Verified against live-boot 1:20230131+deb12u1: substitution applies,
sh -n is clean, hook is idempotent.

needs_full_build() decided the fast path was safe by hashing only config
inputs (VERSIONS, package lists, hooks, archives, auto/config, Dockerfile).
It never hashed the build logic itself, so a change to build.sh or
lib/fast-path.sh counted as a "light" file and the next build silently
reused a squashfs produced by the old code. The merged-usr /lib fix in the
previous commit only forced a full rebuild by accident (the overlay
manifest saw firmware move from lib/ to usr/lib/).
hash_heavy_config now covers every *.sh under iso/builder (build.sh, the
build-*.sh helpers, lib/*.sh) plus auto/. A change to build logic is now
as heavy as a package-list change. config/bootloaders stays excluded (the
fast path regenerates the outer ISO layer from it every time). Hash is
deterministic (LC_ALL=C sort).

Rework the /topo diagram from side-by-side stacked cards into one tall
vertical bar per CPU socket with everything attached to it branching off
sideways (socket 0 left/branches right, socket 1 right/branches left).
Disks are now parented under the storage controller they physically hang
off (SATA/AHCI, SAS HBA, RAID) — itself a NUMA-affine PCIe device under one
socket — instead of a synthetic catch-all node. The disk->controller link
is read from a new storage-controllers.txt techdump
(platform.StorageControllerMapScript, a /sys/block walk); disks with no
resolvable controller fall back to an "Other" bar. No board/root node.

The bundle README is the bootstrap for an agent that knows nothing about
the layout; it listed neither the pcie-link (whole-bus link-retrain) nor
the tpm (read-only) SAT target, so a reader had no pointer to
tasks/bee-sat/pcie-link-* / tpm-* or their summary keys. Add a Fastest-
answers entry for each, refresh the component-status key examples, and add
a Signatures line for the bridge-side link-retrain false positive (bridge
DEGRADED at before==after==max while its downstream endpoint reads OK =
link at the device's native max, not a fault).

The downstream-capability adjustment lowered f.MaxSpeed/f.MaxWidth to the
rate the endpoint supports, but the Degraded verdict still compared the
retrained speed against the stale local maxSpeed holding the bridge's own
uncapped capability. A Gen5 root port feeding a Gen4 HBA (or a Gen2 NIC)
was flagged DEGRADED even though the link ran at the fastest rate the pair
supports, failing the PCIe link check on healthy hardware.
Keep the local maxSpeed in sync with the peer-capped f.MaxSpeed so both
the pre-retrain and post-retrain verdicts use the real target.

pcie-link's retrain check compared post-retrain speed against a port's
max capability without checking whether anything was actually seated
downstream. A switch downstream port with no card plugged in retrains
to zero lanes but still reports a reset-state speed, so it was
misreported as "retrained to Gen1, capable of Gen5" — indistinguishable
from a real degraded link.
Now a port that was already empty before the retrain is skipped (same
treatment as a disabled device: legitimately unpopulated slots are
common and shouldn't fail the check), while a device that answered
before the retrain and disappeared right after it still fails, with an
honest "no device detected downstream" message instead of a fabricated
speed reading.

pcie-nvidia-link.txt, pcie-nvidia-link-under-load.txt, and
kernel-aer-nvidia.txt only ever lived in supportBundleCommands, which
exclusively runs inside the on-demand "Download Support Bundle" web UI
action. The blackbox USB auto-sync worker never calls that function -
it only mirrors whatever CaptureTechnicalDump already wrote into the
live export tree at boot. So these three files were structurally
unreachable from a blackbox pull no matter how fresh the build was;
earlier analysis of a real blackbox misattributed their absence to
build/version drift instead.
Move the underlying scripts into shared exported constants
(platform.PCIeNvidiaLinkScript, PCIeNvidiaLinkUnderLoadScript,
KernelAERNvidiaScript) and add them to techDumpNvidiaCommands, so
CaptureTechnicalDump captures all three once at boot (bee-audit is
oneshot, so the ~8s bee-gpu-burn cost for the under-load sample is a
one-time boot cost, not a per-sync-cycle one) alongside the existing
nvidia-smi-* dumps. supportBundleCommands still re-runs the same
scripts on demand for a fresher sample - that's intentional, not a
duplicate to clean up.

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).

`ipmitool fru edit` frequently exits non-zero after a field resize
(shrinking/growing a string shifts every later offset in the FRU
record) even though the write itself landed correctly on the BMC -
the failure is in ipmitool's own post-write re-parse, not the write.
bee was treating that exit code as authoritative and marking the task
failed even when the field was actually written.
runIPMIFRUWriteTask now re-reads the FRU on a non-zero exit and
compares the target field's actual value before deciding the task
failed, logging which path it took either way.

A CPU that had thermally throttled (sysfs thermal_throttle counter >
0) still reported status "OK" everywhere: dmidecode-derived CPU status
only distinguishes populated/enabled/disabled and never looked at the
throttle flag the collector already recorded next to it, and neither
SAT path meant to catch this actually could:
- The routine "cpu" SAT pack (RunCPUAcceptancePack) only checked
lscpu/sensors/stress-ng exit codes — stress-ng exits 0 whether or
not the CPU throttled while running it, so an 89°C/throttled CPU
right after a "successful" run still showed cpu:all as OK in
component-status.json.
- The more thorough platform-stress test already detected throttling
and fan-spindown correctly, but wrote its verdict as "Overall: FAIL
— ..." with no "=", which parseSATKV can't parse — so even a real
detected throttle event never reached the component-status DB.
Fixes:
- cpu_telemetry.go: escalate a CPU's status to Warning (only-escalate,
same severity ranking already used elsewhere) when Throttled is set.
- sat.go: add a before/after thermal-throttle-counter check job around
the "cpu" pack's stress-ng run, so a throttle event during the run
fails that job and (via the existing FAILED->Warning DB mapping)
flips cpu:all to Warning.
- platform_stress.go: emit a machine-readable overall_status= line
alongside the human-readable verdict so platform-stress results
actually reach ApplySATResultToDB.

An NVMe SSD passed through a RAID/HBA as /dev/sdX (not /dev/nvmeX) gets
smartctl'd over the SCSI protocol, which reports its model in
scsi_model_name/scsi_vendor/scsi_product instead of the ATA/NVMe
model_name field. smartctlInfo only mapped model_name, so the drive's
model was silently dropped from reanimator.json even though smartctl
ran successfully and the serial number came through fine — caught via
a support bundle where lsblk showed "SSSTC CA6-8D1024" for a drive but
reanimator.json's storage entry had no model at all.
Add scsi_model_name/scsi_vendor/scsi_product to smartctlInfo and fall
back to them, in that order, when model_name is empty.

matchesGPUVendor (sat_overlay.go) matched any PCIe DeviceClass containing
the substring "Controller" instead of the actual GPU classes, so a
same-vendor non-GPU device (e.g. an NVIDIA-branded NIC/storage controller)
with a degraded PCIe link surfaced as a pcie:gpu:<vendor> alarm on the
Hardware Summary/webui.
isGPUDevice (app_format.go) had the same bug via a different path: an
"any NVIDIA-vendor device is a GPU" fallback that could inflate the
"GPU: N x <model>" audit summary line with non-GPU companion devices
(NVSwitch/NVLink bridges, etc).
Both now defer to collector.IsGPUClass (exported from the previously
unexported isGPUClass), the canonical exact-match classifier already used
by amdgpu.go — removing the duplicated/incorrect class checks instead of
reimplementing them. Also dedup two more locally-duplicated classifiers
within webui (which doesn't import collector by convention): NIC-class
matching (pages.go/page_topo.go) and GPU-class matching in
page_validate.go now share one copy per package instead of being
reimplemented per file.

pcie:gpu:<vendor> in the component-status DB (what the Hardware
Summary/webui "check passed" status reads) was only ever written by SAT
diag results, and none of the nvidia/nvidia-config/nvidia-interconnect/
nvidia-bandwidth SAT jobs check PCIe link speed. So a real Gen1/Gen4
degradation the collector already flagged as Warning in the hardware
snapshot never reached the DB-backed status, and the audit kept
reporting "OK" despite GPUs training at Gen1 with BMC showing x16.
Add writePCIeGPUStatusesToDB, mirroring the existing PSU write-through,
so RunAudit pushes the collector's PCIe status into the DB alongside
SAT results.
Also add export/gpu/pcie-nvidia-link-under-load.txt to the support
bundle: NVIDIA drivers deliberately downclock PCIe at idle to save
power and re-train to full speed under load, so an idle Gen1 reading
alone can't distinguish real hardware/riser degradation from normal
power management. Resample the same sysfs link attributes while
bee-gpu-burn is actively loading the GPUs so both bundles ship
together.

nvidia-bug-report.sh appends .gz to --output-file when gzip is available,

(cat looked for the uncompressed name that never existed).
Also: a GPU that falls off the PCIe/NVLink bus (Xid 79) or gets flagged
for Node Reboot Required (Xid 154) mid-SAT-run left every downstream test
failing with generic, unrelated-looking errors (CUDA "unknown error",
"unable to determine device handle") with no indication the GPU needed a
physical power-cycle to recover. Detect these codes from SAT run logs and
surface a plain-English "physical reboot required" message in the task's
failure detail, the persisted component-status DB, a dashboard banner on
the Hardware Summary card, and topology diagram GPU-node severity.

enrichPCIeWithNVIDIAData unconditionally overwrote dev.Status after

The NVSwitch-detection fix (983f41a) was necessary but not sufficient on

Neither nvidia-fabricmanager nor DCGM declare the NVLink5 support packages

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.
