# v31 training — raw DINOv2-ViTS/14 teacher (replaces MDGT)
#
# Goal: Benchmark DINOv2 raw as teacher for L_mat.
#   - DINOv2-ViTS/14 is public (Meta, ICLR 2024), cite-able, fully reproducible
#   - Replaces unpublished MDGT checkpoint → paper can be submitted without IP issues
#   - Expected Pearson ~0.55–0.70 (vs 0.80 with MDGT) — establish baseline
#
# Key change vs v29:
#   --teacher dinov2_raw : frozen DINOv2-ViTS/14 CLS token [B,384] as L_mat teacher
#                          (v29 used --no-mat entirely; v31 restores L_mat with public teacher)
#   remove --no-mat      : L_mat is re-enabled
#   --no-mat-stats       : raw cosine targets (no per-identity tanh stats) — v14 behaviour
#                          avoids FVC/SD302 asymmetry that caused collapse in v16/v17
#   --proto-max-batches 0: full dataset prototypes (avoid sensor-biased partial prototypes)
#
# Inherited from v29 (validated):
#   --spread-weight 4.0
#   --concept-deg-gamma 2.0
#   --ortho-weight 3.0
#   --k-cross 0
#   --deg-every-n-steps 2
#
# Expected dynamics:
#   S1 (ep 0-9):  q_std rises 0→15+; l_mat decreases (DINOv2 cosine varies with quality)
#   S2 (ep 20+):  l_pair decreases; l_mat converging; q_std stable 15–22
#   Target:       KS ≤ 0.20, Pearson ≥ 0.55, q_std ≥ 15
