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).
