shadows scored: 44/44 (0 immature/skipped), names total: 352
mean IC: +0.0005 (t=+0.01, n=44, bootstrap p=0.4934) sign hit-rate: 54.5% (null 50%) top-half minus bottom-half realized: -0.0317% per 21 bars
per-date IC (first 10): 2023-01-31:+0.29, 2023-02-28:+0.26, 2023-03-31:-0.17, 2023-04-30:-0.31, 2023-05-31:-0.05, 2023-06-30:+0.33, 2023-07-31:+0.19, 2023-08-31:-0.21, 2023-09-30:-0.64, 2023-10-31:+0.31
VERDICT: WEAK (positive but insignificant — keep shadow, no enforcement) Caveat: backfilled windows may overlap the model's pretraining corpus; treat as directional, confirm on live forward shadows.
