+## Session log: THE LEVEL IS YOU, IN THE LEAGUE — legs and window (2026-08-29, after the merge)
+
+Oliver's deep-test question ("wie wirkt sich mein level aus? werde ich schneller, genauer?")
+exposed two honest gaps: the level's buffs were defensive-only (the plan's serve/accuracy dials
+never landed) and linearly spread over 49 levels — imperceptible where he actually plays
+(level 20, league 4: "autorun schlicht zu langsam, das timing wird zu tight"). His directive:
+gore aside, the league must reward xp SUBTLY but really; level 1 stays the untouchable baseline.
+
+- **profile.bonus() is FRONT-LOADED now**: sqrt of the level fraction (the xp curve's own
+  fast-early logic). Level 20 carries ~0.62 of each cap value; linear gave 0.39.
+- **THE LEAGUE PAIR**, league modes only (`G.match && !G.net` — classic keeps its picker,
+  netplay stays a fair human match, gore untouched): `run` (cap +15%) multiplies INSIDE
+  `assistK()`, so the mover's legs and intercept's reachability can never disagree (the
+  rzChaseSpeed rule, player-side); `window` (cap +20%) widens trySwing's player contact window
+  AND the update() swing-clock expiry that would otherwise close over it — and since quality is
+  centre-normalised, the same millisecond error also scores HIGHER: quicker to the ball, cleaner
+  when there. At level 20 that is ~+9% legs, ~+12% window.
+- Suite 125: level-1 identity, cap bounds, the front-load ratio, the league/netplay/classic
+  gating — and freshSplatter zeroes xp now, because the level feeds real dials and accumulated
+  test awards would silently buff every later test.
