SPEC-EAV-001 v0.2 · Layer L1 Entry logic

L-03 Parameter sensitivity

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

L-03 shows whether performance collapses at neighbouring parameter values. It is produced only where a parameter set has been supplied, and is presented, not judged.

What it examines

Performance at parameter values adjacent to those submitted.

How it is computed

Where a parameter set is supplied, display performance at adjacent parameter values.

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.
