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).

buildNvidiaTaskSet only treated ParallelGPUs as a reason to keep all
selected GPUs in one task, so ramp-up (StaggerGPUStart) fell through
to per-model task splitting. When that split left a single GPU in a
task, resolveNvidiaRampPlan silently returned StaggerSeconds=0,
making the ramp-up toggle a no-op.

Adds POST /api/system/time-sync so the dashboard's "Sync with this
browser" button can set the host's date, time, and IANA timezone from
the client's browser — useful for appliances with no NTP/network
access to keep their own clock straight. Disables NTP before writing
the manual time so it doesn't get immediately overwritten.

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.

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.

Investigating the CG480-S6053 reboot needed a way to run an ad-hoc load
(nvbandwidth across a specific GPU set) while sampling IPMI/nvidia-smi
telemetry in the background — without hardcoding a one-off test into the
SAT pack code for a single investigation.
- audit/internal/platform/scenario.go: ScenarioSpec/ScenarioJob (JSON,
no new dependency) + System.RunScenario. "command" jobs run sequential
or parallel (per-job "parallel" flag); "sampler" jobs run concurrently
in the background on their own interval until every command job
finishes or the scenario's timeout elapses. "{{gpus}}" in a command's
cmd is substituted from that job's gpu_indices. Command jobs are wired
through the same satJobBoundaryHook/satSyncBracketHook seams the SAT
job runner uses, so a scenario run gets the same durability treatment
(evidence that a risky command started/finished reaches blackbox before
a possible crash, not just whatever streamed to the RAM-backed export
dir).
- export.go: ReadScenarioFromRemovableMedia mounts each removable target
looking for scenarios/<name>.json — an air-gapped engineer can author a
scenario elsewhere, drop it under scenarios/ on the same USB stick
already plugged in for blackbox, and run it with no network path onto
the host.
- cmd/bee: new `bee run <file.json|name>` (bare name = looked up on
removable media); `bee scenario run <arg>` kept as a longer alias.
- scenarios/nvbandwidth-all-gpu-power-watch.json: the scenario that
reproduced the actual reboot (full nvbandwidth across all GPUs, which
crashed, vs. clean per-socket passes), with IPMI sensor + GPU power/temp
sampling for a power-delivery correlation check.
Also: webui/page_topo.go — the /topo page's component-status-detail modal
(GET /api/component-detail/{type}) showed "No status data recorded yet"
for any component type ComponentStatusDB has no history for yet (e.g. GPU
before a SAT run this boot), even though the topology card for the same
component already showed "N OK" from the audit inventory snapshot.
inventoryFallbackRecords now synthesizes records from that same inventory
snapshot when StatusDB is empty, using the same device classifiers
(isGPUDeviceClass etc.) and severity mapping (classifyTopoSeverity) the
topology card itself uses, so the two views never disagree.

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.

The long-lived bee-web process (writing PSU/kmsg watchdog records ~every
60s) and each short-lived "bee bee-worker" SAT-task subprocess each held
an independent in-memory copy of component-status.json. Whichever saved
last won outright, silently erasing whatever the other had just written —
e.g. a GPU SAT task's pcie:gpu:nvidia result vanishing the next time the
PSU watchdog ticked. ComponentStatusDB.Record now reloads on-disk state
(keyed by newer LastCheckedAt) before merging its own update.
Also stops re-logging identical repeat observations to History: the
ingest contract defines status_history as a transition log ("История
переходов статусов"), not a per-poll journal, but Record appended one
entry per call regardless — a continuously-polled PSU grew an unbounded
run of identical "still OK" entries. Now only appends when a source's
last recorded status for a key actually changes.
The PSU watchdog itself now backs off (60s -> doubling, capped at 30min)
while steady and resets to 60s the moment any PSU's status changes, cutting
ipmitool shellouts and file writes for a fleet that's been stable for a
while.
Also adds the missing "raid" case to the component-detail API (was
returning 404 for any RAID card's detail click on /topo).

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

the techdump export bundle.

Adds a new card to the web UI Tools page for reading and editing DMI
fields via SAA (In-Band). Reads current DMI configuration with GetDmiInfo,
displays all fields as an editable table, and applies only the changed
fields via EditDmiInfo + ChangeDmiInfo. Backs up the original DMI file to
dmi-backups/ before any write, making it available in the support bundle
for rollback. Also adds "saa" to the standard tool check list.

- 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

RunNvidiaPowerBench already performs a full internal ramp from 1 to N
GPUs in Phase 2. Spawning N tasks with growing GPU subsets meant task K
repeated all steps 1..K-1 already done by tasks 1..K-1 — O(N²) work
instead of O(N). Replace with a single task using all selected GPUs.

- Benchmark page now shows two result sections: Performance (scores) and
Power / Thermal Fit (slot table). After any benchmark task completes
the results section auto-refreshes via GET /api/benchmark/results
without a full page reload.
- Power results table shows each GPU slot with nominal TDP, achieved
stable power limit, and P95 observed power. Rows with derated cards
are highlighted amber so under-performing slots stand out at a glance.
Older runs are collapsed in a <details> summary.
- memtester is now wrapped with timeout(1) so a stuck memory controller
cannot cause Validate Memory to hang indefinitely. Wall-clock limit is
~2.5 min per 100 MB per pass plus a 2-minute buffer.

- Add RampStep/RampTotal/RampRunID to NvidiaBenchmarkOptions, taskParams, and
NvidiaBenchmarkResult so ramp-up steps can be correlated across result.json files
- Add ScalabilityScore field to NvidiaBenchmarkResult (placeholder; computed externally
by comparing ramp-up step results sharing the same ramp_run_id)
- Propagate ramp fields through api.go (generates shared ramp_run_id at spawn time),
tasks.go handler, and benchmark.go result population
- Apply ServerPower penalty to CompositeScore when IPMI reporting_ratio < 0.75:
factor = ratio/0.75, applied per-GPU with a note explaining the reduction
- Add finding when server power delta exceeds GPU-reported sum by >25% (non-GPU draw)
- Report header now shows ramp step N/M and run ID instead of "parallel" when in ramp mode;
shows scalability_score when non-zero

Adds a new checkbox (enabled by default) in the benchmark section.
In ramp-up mode N tasks are spawned simultaneously: 1 GPU, then 2,
then 3, up to all selected GPUs — each step runs its GPUs in parallel.
NCCL runs only on the final step.

- CLI charts: all GPU metric series use single amber color (xterm-256 #214)
- Wallpaper: logo width scaled to 400 px dynamically, shadow scales with font size
- Support bundle: renamed to YYYY-MM-DD (BEE-SP vX.X) SRV_MODEL SRV_SN ToD.tar.gz
using dmidecode for server model (spaces→underscores) and serial number
- Remove display resolution feature (UI card, API routes, handlers, tests)

- Replace diag level 1-4 dropdown with Validate/Stress radio buttons
- Validate: dcgmi L2, 60s CPU, 256MB/1p memtester, SMART short
- Stress: dcgmi L3 + targeted_stress in Run All, 30min CPU, 1GB/3p memtester, SMART long/NVMe extended
- Parallel GPU mode: spawn single task for all GPUs instead of splitting per model
- Benchmark table: per-GPU columns for sequential runs, server-wide column for parallel
- Benchmark report converted to Markdown with server model, GPU model, version in header; only steady-state charts
- Fix IPMI power parsing in benchmark (was looking for 'Current Power', correct field is 'Instantaneous power reading')

- Add parallel GPU mode (checkbox, off by default): runs all selected GPUs
simultaneously via a single bee-gpu-burn invocation instead of sequentially;
per-GPU telemetry, throttle counters, TOPS, and scoring are preserved
- Make queryBenchmarkGPUInfo resilient: falls back to a base field set when
extended fields (attribute.multiprocessor_count, power.default_limit) cause
exit status 2, preventing lgc normalization from being silently skipped
- Log explicit "graphics clock lock skipped" note when inventory is unavailable
- Collect server model from DMI (/sys/class/dmi/id/product_name) and store in
result JSON; benchmark history columns now show "Server Model (N× GPU Model)"
grouped by server+GPU type rather than individual GPU index

Support bundle is now built on-the-fly when the user clicks the button,
regardless of whether other tasks are running:
- GET /export/support.tar.gz builds the bundle synchronously and streams it
directly to the client; the temp archive is removed after serving
- Remove POST /api/export/bundle and handleAPIExportBundle — the task-queue
approach meant the bundle could only be downloaded after navigating away
and back, and was blocked entirely while a long SAT test was running
- UI: single "Download Support Bundle" button; fetch+blob gives a loading
state ("Building...") while the server collects logs, then triggers the
browser download with the correct filename from Content-Disposition

- Burn tab: replace 6 flat cards with 3 grouped cards (GPU Stress,
Compute Stress, Platform Thermal Cycling) + global Burn Profile
- Run All button at top enqueues all enabled tests across all cards
- GPU Stress: tool checkboxes enabled/disabled via new /api/gpu/tools
endpoint based on driver status (/dev/nvidia0, /dev/kfd)
- Compute Stress: checkboxes for cpu/memory-stress/stressapptest
- Platform Thermal Cycling: component checkboxes (cpu/nvidia/amd)
with platform_components param wired through to PlatformStressOptions
- bee-gpu-burn: default size-mb changed from 64 to 0 (auto); script
now queries nvidia-smi memory.total per GPU and uses 95% of it
- platform_stress: removed hardcoded --size-mb 64; respects Components
field to selectively run CPU and/or GPU load goroutines
