# v24 training — Fix orientation_coherence saturation (T39) on top of v23 fixes.
#
# v23 fix (already in code): --concept-deg-gamma 2.0
# v24 additional fix: T39 — orientation_coherence [0] added to dry_skin + wet_press
#
# Problem from v22 eval:
#   orientation_coherence: mean=0.952, std=0.135, p5=0.936, p95=0.989 — SATURATED
#   contrast_uniformity:   mean=0.038, std=0.005 — DEAD (near-constant)
#
# orientation_coherence has NO L_deg target in any degradation → no downward signal
#   → backbone's orientation features map to ~1.0 for every real fingerprint.
#
# T39 fix in src/losses/degradation_ranking.py:
#   dry_skin:  [4, 2] → [4, 2, 0]  (fragmentation → incoherent local orientations)
#   wet_press: [1, 5] → [1, 5, 0]  (ridge merging → false orientation patterns)
#
# v24 settings = v23 settings + T39 concept map update
