- installZones + cannonConfigs through the single cannon path; old centre
plate/boot removed (fork versions supersede); belt+bucket to centre lane
(sunk flush — proud face curbed the line); arch punishes failed MEGA runs
- puddles: distance-based stamping (speed-independent coverage), rate 4/u,
contact tolerance 1.0 (bounce hops starved strips), fork strips widened
toward the racing line + neutral-centre red top-up strip
- under-shelf volumes filled solid in the centre (side corridors left open);
launcher catch widened to the full gap
- verified: naive hold-W finishes ~12s, ghost records+replays, MINI (0.77)
passes the tunnel with 47% pink, buffs activate (GRIP live at 29% green),
78% total coverage on a wandering run

Fixes the live finding that a racer can finish with 0% paint. Paint is now
ROUTE-guaranteed by ground puddles, and colours come in single-colour zones so
buffs actually cross the 20% threshold.
- paint/puddles.ts: PaintPuddle + installPuddles. Flat coloured strips (no
collider) that stamp the blob's underside via skin.splatAtPoint on a ~6/s
cadence while rolling through, emitting paint:splatted. The body doesn't
physically tumble (rotations locked), so an accumulated roll phase walks the
contact point along the travel great circle — a straight run paints a stripe
and coverage climbs instead of piling on the south pole.
- paint/coverage-math.ts: extend computeModifiers with purple MEGA (size→1.45 +
heavier) and pink MINI (size→0.62 + lighter than clean at high %). They fight:
net size uses (purple − pink) strength; mass floored so MINI stays positive.
(Lives here, not buffs.ts, because the pure mapping must stay THREE-free for
the bare-node test; BuffSystem already forwards mods.size/massMul unchanged.)
- paint/coverage-math.test.ts: +MEGA/MINI/fight cases (48 assertions pass).
- course/zones.ts: installZones lays RED/GREEN/BLUE puddles down the centre line
and the PURPLE(left)/PINK(right) fork onto the machine district — a pressure
plate (baseMass*1.25) + boot on the MEGA lane, a visibly-low pink tunnel
(underside y≈1.12) on the MINI lane. Returns cannon configs for integration.
- demo (demos/lane-g.html + src/demo/lane-g.ts): drive the zones, F = hands-free
hold-forward, 1-4 teleport to each zone, live coverage/size/mass + plate HUD.
