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.

The techdump — the only place the IPMI FRU / Elabel identity (Product Name
= server model, serials, part numbers) is recorded — only ran under LiveCD.
Run it on every audit so `bee audit` on an installed host captures it too.
Also add `ipmitool mc info` and `ipmitool lan print` to the techdump, and
pin `ipmitool fru print 0` to FRU device 0 to match the Export Tools
"FRU / Elabel" editor exactly.

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).

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.

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.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Exposes the scenario engine (platform.System.RunScenario, added earlier)
in the web UI instead of only the `bee run` CLI: a new nav item lists every
scenarios/*.json found on mounted removable media (GET /api/scenario/list)
and runs one with a click (POST /api/scenario/run), enqueued as a normal
Task with target "scenario" — progress/logs live in Tasks like any other
SAT pack, no separate live-output UI needed.
- app.go: satRunner gains RunScenario, exportManager gains
ListScenarioFilesOnRemovableMedia/ReadScenarioFromRemovableMedia — both
already implemented on platform.System, just newly exposed through App.
- webui/tasks.go: taskParams.ScenarioName; runTask's "scenario" case reads
the file from removable media, parses it, and runs it.
- webui/page_scenario.go: the page itself.

Replaces the flat export/ + techdump/ + system/ + systemd/ layout (two
same-named-but-different techdump/ dirs, disk reports duplicated between a
SAT run dir and techdump/) with one shared categorizeExportTree used by both
BuildSupportBundle and the blackbox USB mirror:
- export/{cpu,memory,storage,gpu,network,platform}/ — raw vendor-tool
output grouped by device type, plus export/reanimator.json ready to POST
to Reanimator's /ingest/hardware endpoint.
- status/ — computed diagnosis (component-status.json, runtime-health.*,
and metrics.db, previously missing from every bundle entirely).
- tasks/ — bee's own task-run bookkeeping (bee-sat/, bee-bench/, task
reports, service logs) where duplication with export/ is expected.
- livecd/{gui,host}/ — live-boot/kiosk-session-only diagnostics, kept out
of the hardware-facing tree.
Drops the redundant disk-report mirror write in RunStorageAcceptancePack
and the now-dead syncDirectoryTree/removeMissingPaths; adds a size+mtime
skip in copyPath so the blackbox mirror doesn't rewrite unchanged files
every cycle. README.md rewritten to match.

An agent handed a bundle path had no way to know its layout without
grepping through random logs first — confirmed by watching a separate
session read bee-nvidia.log before anything else on a real bundle. Embeds
a single README.md (bee-embed, internal/app/assets/) explaining what bee
is and giving direct answers to the questions someone analyzing a bundle
is most likely to ask (did the tests pass, what hardware is this, is a
service healthy, RAID/GPU/NVLink state, etc), written at the bundle root
by both BuildSupportBundle (support-bundle archive root, sibling of
manifest.txt) and blackboxWorker.syncCycle (removable-media boot-folder
root, which otherwise has no manifest.txt-equivalent pointing anywhere).

The standalone "confidential-computing" SAT target only ever checked CC
readiness, which most fleets never opt into (a NOT_READY verdict there
isn't a fault). Meanwhile DCGM diag never asserts GPU config compliance
(ECC/MIG/power-limit vs factory default) or NVLink topology (per NVIDIA's
own DGX BasePOD deployment guide, this needs a separate validation step)
— gaps confirmed against public DCGM docs and a real NV17-vs-expected-NV18
bonded pair found on a live bundle.
Repurposes the routine into "nvidia-config": reuses the existing
ListNvidiaGPUSettings() (already backing the GPU-settings page) to flag
ECC disabled, a MIG mode change stuck pending a reset/reboot, and a power
limit capped >5% below default; parses "nvidia-smi topo -m" bonded pairs
against "nvlink -s/-e" to flag any inactive lane or nonzero replay/
recovery/CRC counter on an otherwise-active bond. CC readiness is folded
in as one informational field (does not gate overall_status) rather than
a dedicated test. Reports under the same pcie:gpu:nvidia severity key as
every other nvidia-* SAT target instead of an isolated key, so a
config/NVLink FAILED result isn't invisible next to stress-test results.
Also fixes ApplySATResultToDB silently dropping any target with no
matching switch case (exactly what the old confidential-computing target
did) with a new coverage test enumerating every real SAT target.

Adds a GPU Settings card to /tools for the settings that actually
persist on NVIDIA data-center GPUs: ECC mode, MIG mode, and
Confidential Computing mode (all stored in the GPU's inforom/firmware,
take effect after a GPU reset or reboot) plus power limit (does not
persist — reapplied on demand). Includes a one-click "Reset All to
Defaults" that restores factory settings across every visible GPU,
touching only whatever has actually drifted.

New read-only visualization page: CPU sockets as anchor nodes, PCIe
devices (GPU/NIC/RAID) linked to their NUMA-affine socket with edge
color derived strictly from link_speed vs max_link_speed (not from the
device's own Status, which can also be overwritten by SAT-test results
on the same field), PSU/BMC as standalone boxes with no connecting
line, and a separate NVLink Topology card (live nvidia-smi topo -m /
nvlink -s/-e queries, not persisted to any contract).
GPU-GPU edges are drawn strictly from the actual bonded-pair list
parsed out of "nvidia-smi topo -m" (parseGPUPairAdjacency), not from
adjacent box position in the layout — an earlier ASCII mockup drew a
"chain" through unrelated GPUs, which a dedicated regression test now
guards against. A bonded pair spanning two different NUMA nodes is
flagged Warning on the edge and on both GPU boxes, per project
decision that this is an anomaly worth surfacing, not a neutral fact.
Zero changes to the ingest contract: this reverts the HardwareNVLinkPort/
HardwarePCIeDevice.NVLinks field shipped in v11.55 (33d6eee) along with
its collector/nvidia.go enrichment — that field risked a 400 from
Reanimator Core's strict decoder without an RFC, and isn't needed since
the topo page queries nvidia-smi directly instead of reading it from
audit.json. The v11.55 systemd fix (bee-nvidia.service ordering,
nv-hostengine restart) and the nvlink-status/-errors/dcgmi dumps in the
support bundle are untouched.
Also reorganizes support bundle collection per project convention:
system/ is now LiveCD-operational logs only (Xorg, services, console,
network/FS of the host itself); all server-hardware dumps (lspci,
NVIDIA/NVLink/DCGM, fabric manager, PCIe AER, ethtool, mstflint) move
to techdump/, deduplicating two entries already produced by
platform/techdump.go. Adds nvidia-bug-report.sh (previously only
collected inside the NVIDIA SAT pack) and lscpu to the always-on dump.

New read-only "Check" step reports whether this server can run NVIDIA
Confidential Computing: CPU TEE support (Intel TDX / AMD SEV-SNP, via

`nvidia-smi conf-compute -q`). Also collect that command's output into
the techdump export bundle.
