# v23 training — Fix Track 4 concept grounding failures from v22.
#
# v22 eval results (KS=0.1527, Pearson=0.4433) — Track 2 PASS.
# v22 Track 4 failures:
#
#   blur → continuity   XX+0.261  (should be negative)
#   jpeg → continuity   XX+0.184  (should be negative)
#   occlusion → minutiae_reliability  XX+0.067  (should be negative)
#   dry_skin → contrast_uniformity   XX+0.504  (should be negative)
#
# Root cause: --concept-deg-gamma 0.5 is too weak.
#   Gaussian blur naturally SMOOTHS ridges → model's continuity feature increases
#   with blur. L_deg with gamma=0.5 cannot overcome this natural correlation.
#   contrast_uniformity is only targeted by dry_skin once → single weak signal.
#   minutiae_reliability for occlusion similarly has a weak signal.
#
# v23 fix: --concept-deg-gamma 2.0 (vs v22's 0.5 — 4× stronger concept supervision)
#   All other settings are identical to v22.
#
# Note: orientation_coherence saturation (mean=0.952, always near 1.0) is NOT
#   fixed in v23. It requires adding concept[0] to dry_skin and wet_press targets
#   in DEGRADATION_CONCEPT_MAP (T39 fix, applied to src/losses/degradation_ranking.py).
#   v24 will include this fix.
