Honest caveats
- Universe = today's SP500 — survivorship-biased; delisted losers excluded.
- IC sample is 20 monthly rebalances over ≈ 2 years — minimal statistical edge.
- Catalog is regime-tuned: BULL today (different weights kick in if regime flips).
- Forward record is real prices, equal-weight, no costs or slippage modelled.
- Rolling-IC track (G8) is an additive forward experiment — weights = each factor's trailing realized IC (no look-ahead, ≤ today's history only). The fixed-weight composite stays the production default; both NAVs accrue side-by-side pending forward evidence. IC history caliber (G8O): honest next-open — each IC is measured enter open[t+1] → exit open[t+1+H], not the legacy close[t]→close[t+H]. P1b found the two calibers near-isomorphic (composite rank corr ≈0.95); the pre-switch stretch is a retroactive recompute from the point-in-time panel pile (no look-ahead), not a live day-by-day accumulation.
