Runs the two surviving threads (H1 breakout, vol-normalized H1 momentum) across the 21-instrument gapless universe under the wide-stop regimes, beside an always-long beta control on the same matrix. The breakout dies everywhere (beta on trending assets, significantly negative on FX); momentum shows a one-sided positive cross-sectional tail with five double-regime flags, of which FRA40 (both regimes) and NatGas (k6) beat the no-signal baseline outright — the only control-beating cells of the whole program. Includes the engine performance envelope (single run 2.97 s vs Arc-0 ~3 s; 11-13 s/cell; executor fan-out findings refs Brummel/Aura#268, data-gap abort refs Brummel/Aura#264).
