- 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.
