The latch is stale-proof by construction, the cup divisor honest, the trail visible

Oliver's tournament freeze was the stale latch by a THIRD route:
matchFallWillPlay kept the deathmatch /4 while cup matchPoint divides by
4*need, so it promised a fall on a no-crossing point — whose synchronous
matchReady left the after-set latch scoping a dead rally. No more ordering
arguments: the latch is set BEFORE the resolve, the swallow exempts the
in-progress resolution via G.matchEarly, and every path that arms a rally
clears it in matchReady. willFall now mirrors the cup divisor exactly and
knows a mid-round game keeps its body. Regression test drives the full QF
sequence (no-crossing points, the fall, the mid-round game, game two).

And the two 'not really' reports: the trail's 0.26 alpha was tuned on the
gore palette and vanished on the bright lawn — 0.38 now, gate at 13 m/s;
oppBright 1.18 -> 1.3.
