Calibration loss ↗
Stored or effective calibration no longer represents the sensing chain.

Degradation ↗
Measurement performance deteriorates over service time or exposure.

Drift ↗
A reported value changes because the measurement baseline changes.

False negative ↗
A detector fails to report a target or event present under the evaluation definition.

False positive ↗
A detector reports a target or event that is absent under the evaluation definition.

Intermittent failure ↗
Signal availability or validity is interrupted unpredictably.

Saturation ↗
The reported output clips or ceases to distinguish larger inputs.
