Named-setup analog on these three

Research analog, not a forecast. Close-to-close after the first session a named setup clears min_score. Onsets are at least 21 sessions apart. A win on a buy is a higher close 21 sessions later, net of 10 bps. A win on a sell is a lower close. Hit rate is always shown next to the same names' unconditional 21-session rate. Mag7 thresholds (n ≥ 40, n_eff ≥ 40) are reported for comparability, but this walk can never earn a cleared grade: on one name n_eff equals n by construction, so read n_episodes — onsets grouped into quarter-wide windows — as the independence count. One long drawdown re-arms a washout setup every quarter and shows up as many onsets. The names were also selected because they jumped today, and the $10B floor is measured today while the history covers the era when the name was far smaller.
