shadows scored: 70/70 (0 immature/skipped), names total: 3500
mean IC: -0.0248 (t=-1.28, n=70, bootstrap p=0.9012) sign hit-rate: 49.1% (null 50%) top-half minus bottom-half realized: -0.2772% per 21 bars
per-date IC (first 10): 2020-11-15:-0.19, 2020-12-15:-0.18, 2021-01-15:+0.10, 2021-02-15:-0.01, 2021-03-15:-0.16, 2021-04-15:-0.06, 2021-05-15:-0.28, 2021-06-15:+0.05, 2021-07-15:-0.21, 2021-08-15:+0.14
VERDICT: NONE (no signal — do not wire into any sleeve) Caveat: backfilled windows may overlap the model's pretraining corpus; treat as directional, confirm on live forward shadows.
