Full cohort drift analysis between two time points.

Fields

n_entities: usize

Number of entities successfully analyzed (with data at both t1 and t2).

mean_drift_l2: f32

Mean individual L2 drift magnitude across the cohort.

median_drift_l2: f32

Median individual L2 drift magnitude.

std_drift_l2: f32

Standard deviation of individual L2 drift magnitudes.

centroid_drift: DriftReport

Drift of the cohort centroid between t1 and t2.

dispersion_t1: f32

Mean distance from entities to centroid at t1.

dispersion_t2: f32

Mean distance from entities to centroid at t2.

dispersion_change: f32

Change in dispersion: positive = diverging, negative = converging.

convergence_score: f32

Cosine alignment of individual drift vectors (0 = random, 1 = all same direction).

top_dimensions: Vec<(usize, f32)>

Top-N most changed dimensions aggregated across the cohort.

outliers: Vec<CohortOutlier>

Entities flagged as outliers (|z-score| > 2.0).
