  "note": "Board-telemetry energy basis per (gpu_type, form_factor): kWh consumed per GPU-hour under a saturating load, read from each board's own power telemetry (nvidia-smi power.draw). Captured 2026-06-01 on rented SXM GPU instances (build-sequence step-3 calibration) via the gpu_validation_run.py then calibrate.py harness. standard_values.py overlays this constant over the modeled TDP defaults, so a certificate's normalization_basis_kwh derives from it and every RCC carries basis_provenance 'telemetry'. The means land at about 99.5% of vendor TDP, so this is board telemetry under load, effectively the vendor's number, not an independent reading; the label 'measured' is reserved for a future external certified analyzer (DD memo 2026-07-10 item 1).",
