# v25 training — T40 fix: address 3 remaining Track 4 failures from v24.
#
# Changes from v24:
#   1. DEGRADATION_CONCEPT_MAP (T40 in src/losses/degradation_ranking.py):
#      blur:  [1, 2]    → [1, 2, 0]  (+orient_coh: blur smears orientation fields)
#      noise: [3]       → [3, 4]     (+contrast_u: noise disrupts local contrast)
#      jpeg:  [2, 1]    → [2, 1, 4]  (+contrast_u: JPEG blocking creates contrast bands)
#      dry_skin/wet_press/occlusion: unchanged from T39
#
#   2. --concept-deg-gamma 1.5  (down from 2.0)
#      gamma=2.0 caused noise→noise_lv REGRESSION (+0.365 in v24).
#      gamma=1.5 keeps enough signal for blur/jpeg (needed >0.5) while
#      reducing saturation pressure that triggered noise_lv inversion.
#
# Expected improvements:
#   noise → noise_lv:     +0.365 → negative  (gamma reduced + noise now 2-concept)
#   dry_skin → contrast_u: +0.051 → negative  (3 degradations now target contrast_u)
#   dry_skin → orient_coh: +0.008 → negative  (blur gives orient_coh strong signal)
