Build holdout v4 from the public AA set, correct the two v3 dates, and sweep
R1–R5 plus pairs offline. No production scoring defaults change. No
implementation brief: delivered width stays the full window on every radius.
Offline H1-H4 measurement on 20 public AA holdout cases.
Block unique top-1 did not rise; H4 made it worse; minute layer unchanged.
Leave production scoring untouched. Transits must not drive minute conclusions.
