Leaves: a pooled handful (cap 7) streaming with the wind from 8.3 m/s — the
same number D keys the player's lean on, so the yard and the body start
telling one story at one speed. Count rides a 2.5 s speed EMA so it doesn't
strobe; own seeded rng (seed ^ 0x1eaf) so the pool never shifts the crate
sequence; bit-identical under identical (dt, t) streams (asserted).
debris.clear() rewinds the layer. dev_skyfx flies the debris layer now and
warms it to the scrub point, so ?t=50 shows the leaves t=50 would have.
D's aftermath sliver, exactly as diagnosed on lane/d: the hail InstancedMesh
at count:0 with frustum culling and depthWrite off still draws instance 0's
identity matrix — a 5 cm always-on-top speck at the origin. mesh.visible now
gates on n > 0, sky.hail joins the public fx object, and a whole-storm assert
demands hidden-at-zero / shown-when-falling in both directions (gated on
floor(1300 x intensity) >= 1: a burst's first frames honestly draw nothing).
THREADS: gate-2 wrap entry — D's judging unblocked, A's M key live.
Selftest 340/0/0 (+2 tests). Mutation-checked: dropped stepLeaves, a 3 m/s
threshold, and an always-visible hail pool all go red.

Every windchange event gets an in-world tell: a dark bank standing on the
horizon in the quarter the new wind comes FROM, rising across the 12 s
before the change and clearing after the swing, plus a low distant rumble
layer in the audio. Soft-edged via vertex alpha (the hard band read as a
floating rectangle on the bench). Deterministic off (dt, t): progress is a
pure function of t, azimuth comes from dirAt at a fixed post-change
instant. Night 2 teaches the tell at ~18 s; night 3 shows the same wall at
t=6, which is 'looks like night 2 and isn't' made visible.
dev_skyfx.html: the skyfx bench — one storm, bare ground, scrubbable
clock, so the tell can be judged by eye without playing to night 3.
Two new asserts in c.test.js (window, monotonic rise, direction, mesh
orientation, changeless storm stays clear, bit-exact determinism).
Selftest 322/0/0.
