B-4. The gate used to run on my own stub wind — uniform, horizontal,
tuned by nobody — so it proved the cloth was self-consistent, not that
the game works. It now loads the shipped storm JSON and drives the cloth
through weather.core.js (pure and import-free, so the same path runs in
node and in selftest.html; weather.js's own loadStorm can't help because
its STORM_DIR is a file:// URL that node's fetch won't open).
All three halves of §7 now run on real storm_02 and the real yard:
a flat drum-tight carabiner rig cascades 4/4; a well-twisted mixed rig
holds all four; and a twisted rig with one dodgy corner blows it and
finishes 4/4 intact after a single repair — the DoD scenario, in an
assert.
Perf: Lane C added an `out` param to wind.sample specifically so sail.js
wouldn't allocate, and I wasn't passing it — 162 faces at 60 Hz is ~9.7k
throwaway Vector3s a second. Now passing a scratch vector. Stub winds
that ignore `out` still work; we read the return value.
Two tests skip rather than pass vacuously while Lane C's downdraft is
unmerged: a "nothing broke" repair scenario would go green forever and
check nothing. Both light up by themselves on merge, and the repair one
hard-fails if a downdraft IS present and still can't threaten the rig.
