SPRINT2 §Lane A steps 1-4. The placeholder capsule and stub wind are gone; every
lane's proven module now runs in one yard.
Wind goes through a router. Every consumer binds to `wind` exactly once at
construction — the yard closes over it for tree sway, createPlayer takes it in
opts, createDebris reads its event stream — so swapping storm_01 for storm_02 at
the phase change has to be a re-point, not a re-wire, or half the game would
still be sampling a calm day while the other half is in a gale. Shelters apply to
every storm, since the trees don't stop existing when the weather turns.
skyfx is rebuilt rather than re-pointed: it reads the storm's sky block at
construction. Verified its dispose() hands world.sun/world.hemi back exactly
(2.0/1.8 after a 40 s storm had them at 1.07/1.13) and that nothing compounds
over repeated phase cycles — that was Lane C's §Lane C.5 ask.
Two seams needed care. createSailView reads rig.pos/rig.tris, which don't exist
until attach() allocates them, and a re-rig can change the grid — so rigSail() is
the one door both boot and Lane B's picking adapter come through, rebuilding the
view and re-wiring interact (whose targets close over a corners array that
attach() replaces). And knockdown(t, dirX, dirZ) takes the sim clock first, not
the impact: passing debris impact there would jam ~40 into the state machine's
start time and the player would never get up.
Storm_02 verified end to end by hand: the carabiner blows at t=45.4 s, and p2's
shackle cascades at t=56 s — one second after the southerly change. Coverage over
the bed is 1.0 intact and 0 once two corners are gone, which is the whole game in
one number. 0.63 ms/frame (0.17 sim + 0.45 render) against a 16.67 ms budget.
Selftest 121/0/0.
