The QA pass's biggest player finding: 'stands bolt upright and unbothered'
at 65 km/h. E rendered the two Mixamo lean candidates and rejected both on
screen, and proved the deeper reason a clip can't do this: _rotOnly drops
Hips.quaternion from every clip at load, so a baked lean is discarded, and
a clip's lean axis is fixed while the wind's bearing swings. So the lean is
the ROOT, the same machine as the knockdown pitch and climbY lift.
sim (player.sim.js): sim.lean 0..1 + sim.leanDir, eased over leanSecs.
Magnitude off windBase (the ~4s EMA), NOT raw windSpeed — measured: raw
strobes the posture 8-18x/min across the storms, windBase settles it to 0-2
changes per 90s. Sustained wind = posture; the gust is already the
stumble/knock event. Suppressed on your back (pitch owns the body), braced
(TakeCover is its own hunch), and up a ladder. Bands land on the storm
rating ladder: night 1 upright, 2-3 lean, 4-5 in the gale.
view (player.js): a foot-pivot tip toward leanDir, max leanMaxRad (~17deg,
a third of a knockdown's pi/2), composed under the yaw. It's the else branch
of the pitch tip by construction — the sim guarantees lean=0 whenever
pitch>0, so they never fight.
Three asserts: magnitude scales with sustained speed, a lone gust does NOT
snap you over (windBase inertia), and it's downwind + suppressed when
floored/braced/aloft. Mutation-checked: forcing lean to 0 reddens two.
Verified live at 71 km/h — leanDir dot wind = 1.0, the figure visibly
braces. Selftest 340/0/0. This is the root lean E asked me to wire first;
whether their WindPosture additive follows is a look-at-it-together call.
