L-01 Stability of signal frequency

Reference output only. This item is presented, never judged — judging the merit of entry logic would break P-01.

L-01 reports the stability of signal generation over time. It is presented, not judged, so that the reader can determine whether the logic operates only within a particular regime.

What it examines

Signal generation frequency across the record.

How it is computed

Frequency of signal generation over time, reported as a series.

Judgment states

PassThe structure is observed and meets the threshold.
CautionThe structure is observed but sits at the boundary of the threshold. Evidence figures are presented alongside.
DefectThe structure is not observed, or clearly falls outside the threshold.
Not judgeableThe required input data is absent. Marked distinctly from a pass.

Threshold

Not fixed. Determined from calibration data. See SPEC-EAV-001 §11.
