+Build 86 replaces that inconclusive three-hour exit with a narrower rule that
+survived a corrected 2,000-market audit. Across 534,894 hourly observations,
+the exact accelerating three-hour shock / 8–25% opposite-side longshot / 24-hour
+exit rule retained positive 90% lower bounds in train, validation, chronological
+holdout, and a sealed event-disjoint holdout at one-cent modeled cost. The four
+partitions contained 69, 70, 104, and 56 independent events respectively. It
+did not survive a two-cent stress test, so live candidate construction requires
+entry friction of at most half a cent and grades the future exit at the actual
+executable bid with another 0.25-cent slippage buffer. Backtest-approved paper
+positions begin at 0.5% of equity and total shock exposure is capped at 3%.
+Thirty positive forward events with a lower bound above 1% can raise individual
+size to 1%; twelve convincingly losing events or a 2% strategy loss demote the
+lane to zero capital. Strategy-1 outcomes do not contaminate Strategy-2 evidence.
