Multiple-testing survival: White RC, SPA, FDR, deflated Sharpe on C-E output

Status: completed 2026-08-12 — survival curve measured: 372 -> 232 (naive) -> 226 (FDR) -> 68 (SPA, 18%), all gross; survivors dominated by bounce; the known SPX artifact survives SPA (statistical correction != artifact correction). Double-filtered pool -> expG.
