Struct AcThresholds 

pub struct AcThresholds {
    pub gain_warn_db: f64,
    pub shape_rms_fail_db: f64,
    pub shape_spectral_fail_db: f64,
    pub thd_error_fail_db: f64,
    pub harmonic_fail_db: f64,
    pub response_tilt_fail_db: f64,
}

Thresholds for grading the AC dimensions. Informative (localizes which dimension carries the error), not a hard CI gate.

Fields

gain_warn_db: f64

A |gain| above this at the test tone counts as a LEVEL offset. 1 dB.

shape_rms_fail_db: f64

Gain-normalized RMS shape residual (dB) above which SHAPE is bad. The residual is 20·log10(rms(wdf_norm − golden)/rms(golden)), so −20 dB (≈ 10 % shape difference) is the boundary. NOTE: this is phase- SENSITIVE — a pure group-delay difference inflates it even when the magnitude shape agrees; cross-check with shape_spectral.

shape_spectral_fail_db: f64

Gain-normalized, phase-IMMUNE in-band magnitude shape error (dB) above which SHAPE is bad. 3 dB.

thd_error_fail_db: f64

|THD_wdf − THD_golden| (dB) above which HARMONICS are bad. 6 dB.

harmonic_fail_db: f64

Max per-harmonic dBc error above which HARMONICS are bad. 6 dB.

response_tilt_fail_db: f64

Response tilt (max−min gain across the sweep, dB) above which the error is frequency-SHAPED (a RESPONSE error, not a flat scalar). 3 dB.
