+# Phase I5e — MMP Quintile CSI300 Independent Generalization Check
+# (EXPLORATORY, NOT a performance claim).
+#
+# Freezes the accepted I5d MMP quintile grouped-backtest machinery and re-runs it
+# on an INDEPENDENT universe — CSI300 (000300.SH) — over the SAME full window
+# (2021-06-01 .. 2026-05-31). Purpose: test whether the Q1->Q5 MMP monotonicity
+# seen on CSI500 (PR #39) attributes to the factor rather than to the original
+# universe/regime. The MMP math, equal-count bucket semantics (Q1 = lowest score,
+# Q5 = highest), the I5a/I5b intraday tail event model (14:50 decision / 14:51
+# execution, exec-to-exec returns), raw stk_limit execution feasibility, and the
+# cache-only minute loading are ALL UNCHANGED from I5d — only the universe and the
+# report labels differ. No tuning, no learned alpha, no new factors.
+#
+# Minute bars are read from the EXISTING intraday cache ONLY on the monthly anchor
+# dates (read-only; a miss is a hard blocker -> zero stk_mins live calls).
+# require_cache_coverage=false drops the minute-uncovered constituents (DISCLOSED
+# in the report; the WINDOW is NOT shortened). Daily endpoints and raw stk_limit
+# flow through the same P4 read-through cache as I5d; CSI300 daily history that is
+# not yet cached is fetched via that read-through path exactly as I5d did for
+# CSI500. The token is never printed or written.
