Mirrors the runner track: slides detect_liquid_intraday_breakout over RTH history, emits
non-tradeable liq1 setups scored by _forward_labels, stratifies +1R by rvol + cumulative
dollar-volume. Pre-registered bar locked 2026-07-01. Early in-sample read (5 days, 1511 fires):
+1R 51% beats ORB 35% on same days, but median 60m upside only +0.6% (tight-stop artifact);
rvol/liquidity strata flat. SHADOW-ONLY. Full 26-day out-of-sample build pending.
