What this proves and what it doesn't
We report what we measured at each inspection, with explicit uncertainty bounds. We never claim “guaranteed factory original.” Read the full methodology at how it works.
How we measure
- •Tamper-evident hash chain — every inspection cryptographically links to the prior one.
- •ISO/IEC 17025 measurement uncertainty framework (Type A statistical, Type B calibration, Type C factory variance).
- •Patent-pending GUM-compliant scoring engine.
- •Calibrated DeFelsko PosiTector instrumentation only.
