- 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

When --query-gpu CSV fields fail (exit status 2 on some Blackwell +
driver combos), enrichGPUInfoWithMaxClocks now also parses from the
verbose nvidia-smi -q output already collected at benchmark start:
- Default Power Limit → DefaultPowerLimitW
- Current Power Limit → PowerLimitW (fallback)
- Multiprocessor Count → MultiprocessorCount
Fixes PowerSustainScore=0 on systems where all three CSV query
variants fail but nvidia-smi -q succeeds (confirmed on RTX PRO 6000
Blackwell + driver 590.48.01).

Before the per-GPU compute phases, run `dcgmi diag -r targeted_power`
for 45 s while collecting nvidia-smi power metrics in parallel.
The p95 power per GPU is stored as calibrated_peak_power_w and used
as the denominator for PowerSustainScore instead of the hardware default
limit, which bee-gpu-burn cannot reach because it is compute-only.
Fallback chain: calibrated peak → default limit → enforced limit.
If dcgmi is absent or the run fails, calibration is skipped silently.
Adjust composite score weights to match the new honest power reference:
base 0.35, thermal 0.25, stability 0.25, power 0.15, NCCL bonus 0.10.
Power weight reduced (0.20→0.15) because even with a calibrated reference
bee-gpu-burn reaches ~60-75% of TDP by design (no concurrent mem stress).

- BenchmarkHostConfig captures CPU model, sockets, cores, threads, and
total RAM from /proc/cpuinfo and /proc/meminfo at benchmark start.
- BenchmarkCPULoad samples host CPU utilisation every 10 s throughout
the GPU steady-state phase (sequential and parallel paths).
- Summarises avg/max/p95 and classifies status as ok / high / unstable.
- Adds a finding when CPU load is elevated (avg >20% or max >40%) or
erratic (stddev >12%), with a plain-English description in the report.

clocks.max.graphics / clocks.max.memory CSV fields return exit status 2 on
RTX PRO 6000 Blackwell (driver 98.x), causing the entire gpu inventory query
to fail and clock lock to be skipped → normalization: partial.
Fix:
- Add minimal fallback query (index,uuid,name,pci.bus_id,vbios_version,
power.limit) that succeeds even without clock fields
- Add enrichGPUInfoWithMaxClocks: parses "Max Clocks" section of
nvidia-smi -q verbose output to fill MaxGraphicsClockMHz /
MaxMemoryClockMHz when CSV fields fail
- Move nvidia-smi -q execution before queryBenchmarkGPUInfo so its output
is available for clock enrichment immediately after
- Tests: cover enrichment and skip-if-populated cases

- nvidia.go: add Name field to nvidiaGPUInfo, include model name in
nvidia-smi query, set dev.Model in enrichPCIeWithNVIDIAData
- pages.go: fix duplicate GPU count in validate card summary (4 GPU: 4 x …
→ 4 x … GPU); fix PSU UNKNOWN fallback from hw.PowerSupplies; treat
activating/deactivating/reloading service states as OK in Runtime Health
- support_bundle.go: use "150405" time format (no colons) for exFAT compat
- sat.go / benchmark.go / platform_stress.go / sat_fan_stress.go: remove
.tar.gz archive creation from export dirs — export packs everything itself
- charts_svg.go: add min-max downsampling (1400 pt cap) for SVG chart perf
- benchmark_report.go / sat.go: normalize GPU fallback to "Unknown GPU"

- 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

PowerSustainScore now uses DefaultPowerLimitW as reference so a
manually reduced power limit does not inflate the score. Falls back
to enforced limit if default is unavailable.

- Sample server power (IPMI dcmi) during baseline+steady phases in parallel;
