Textures (SPRINT2 §Lane E-2). sail_weave.png is a seamless 512² knitted
shade-cloth weave with the stripe banding real cloth has; the script proves the
wrap by evaluating a second tile and requiring an exact match, because Lane B is
being told to set RepeatWrapping and a bad wrap would seam across the whole
sail. Luminance rides in a narrow band so it multiplies the base colour instead
of replacing it — high contrast reads as burlap, not HDPE. Dropped the per-pixel
noise: invisible at ±0.012 and incompressible, it cost 305 KB of the 323.
sail_tears.png is a strip of 4 escalating rips. Each is a lens, not a slit —
fabric under tension parts widest in the middle and tapers to a point, and a
constant-width gap reads as a drawn line. Threads bridge the gap, scaled to the
local width; without them a dark lens is a hole rather than a tear.
Dressing (§Lane E-3): wheelie_bin_01 (240 L, 12 kg, `lid` on its own node so it
flaps before the bin goes over), washing_line_01 (a Hills Hoist — the `head`
freewheels, giving a second wind tell at head height), garden_gnome_01
(collateral bait: a smashed gnome reads where a damage number doesn't).
Bin and tramp land in models/debris/ for Lane C to glob. All 19 assets pass, 28
output files byte-identical across two runs, selftest 129/0/0.

world.js sways a tree by rotating a `canopy` group whose origin sits at the
trunk top, so the blobs swing about the trunk. The trees shipped canopy_01..03
as siblings of `trunk` with each origin at its own blob centre — rotating one
spins a sphere in place, which is visually nothing. Lane A could not have swayed
these trees, and the canopy lean is the gust telegraph the player reads a beat
before it hits the sail, so the tell would have gone missing rather than looked
wrong.
Adds the `canopy` empty at the trunk top with the blobs parented under it, so
A's existing code works unchanged, plus sway_amp / sway_phase / sway_pivot_y
for the per-tree tuning SPRINT2 §Lane E asks for (gum_01 is big and leans less
at 0.85; gum_02 is whippy at 1.20 and shows a gust first).
sway_phase draws from its own RNG stream: taking it from the shared one would
consume a value and shift every blob draw after it, resilhouetting a tree the
other lanes have already tuned against. Exported dims are identical to Sprint 1.
e.test.js asserts the pivot by rotating the handle and measuring that a blob
actually travels — red before this change, green after.

player.sim.js Deterministic core, zero imports: camera-relative movement, the
state-machine table, wind slow/gust-shove/knockdown. step(dt,t)
is the whole clock — no Date.now, no Math.random, no rAF — so a
storm fast-forwards identically in selftest and in the game.
player.js The view: rig load per the 90sDJsim DEVMANUAL rig rules
(SkeletonUtils.clone, height-normalise off the MEASURED head
bone, canonicalised bone namespace), clip retarget, and
createPlayer() satisfying the Player contract.
interact.js Hold-E with radial progress + wireYardActions (re-rig 2.5 s,
turnbuckle trim 1.2 s, carry-one-item), duck-typed so it no-ops
cleanly until Lane B lands sailRig.repair/trim.
d.test.js 20 asserts in Lane A's harness: 38 pass / 3 skip overall.
Ported from the 2D prototype's shape (game.js:250-252), retuned to m/s: the
slow curve, and shove gated to gusts only and scaling with speed² so gusts have
teeth. Knockdown needs 0.5 s of SUSTAINED overload — deliberately the same rule
as a sail corner letting go, so cloth and people speak one language.
Two decisions worth the review:
- The knockdown pitches the root in code rather than playing the Falling clip's
root. Shared clips must drop Hips.quaternion (a different-orientation source
lays the target flat), so a clip physically cannot lie the body down. Doing it
in code also lets the fall go DOWNWIND of the gust that caused it, which a
canned clip could never do, and keeps it deterministic.
- Gust magnitude is recovered from a slow EMA of local wind rather than widening
Lane C's contract: wind.sample() gives the total and gustTelegraph() only fires
BEFORE a gust, so nothing reports gust size during the hold. The EMA
self-calibrates to whatever storm JSON Lane C authors.
Verified in a real scene, not only in asserts: head bone 1.715 m at fig scale
0.983, all six clips bound, walk/run at the tuned speeds, the body lies down and
gets back up, hold-E fires exactly once per press.

Verifying the GLBs in three.js (not just Blender) showed four assets reporting
inflated bounds: tramp_01 came back 3.29 x 1.27 m against a true 2.96 x 0.78.
Box3.setFromObject expands each mesh's LOCAL box by the world matrix, so a node
carrying a rotation over-reports — the same trap Blender's obj.bound_box sets,
and what three uses for frustum culling. Joined nodes inherited parts[0]'s
rotation, which for an arc is half a segment step off-axis.
Applying rotation at join time makes every local box axis-aligned, so the
default Box3 path is now correct for consumers and culling is tight. World
geometry is unchanged; the exported dims are identical.
Adds tools/assetcheck/, the three.js harness that caught this. It's the only
check that can: a Blender round-trip exports Z-up->Y-up and imports Y-up->Z-up,
so a broken export_yup flips back and passes green.

16 generated assets plus the grass billboard atlas and the four debris models
copied verbatim from the 3D-STORE library (copies rule, §0). All meter-scale,
Y-up, and far under the 15k tri budget — garden_bed is heaviest at 2,580.
Regeneration is byte-deterministic: two consecutive runs produce identical
files, so re-running the factory causes no churn.

One script regenerates every nature/hardware asset in PLAN3D §5-E, following
the house idiom from 3D-STORE/racks_to_glb.py: reset per asset, build under a
root empty at the origin, join by group, stamp props, export Y-up GLB.
Groups are joined per sway-unit rather than per-asset, so trees keep trunk and
canopy_* as separate nodes for Lane A to animate. Paths resolve from __file__
instead of a hardcoded home dir, since the library lives elsewhere on this box.
Verification re-imports each exported GLB from disk and asserts dims, tri
budget, and node-name survival, then renders it against the 1.7 m ref capsule.
Checking the file rather than the in-memory scene is what makes it a real test.

Character is a byte copy of 90sDJsim's man_casual_01 ped (already metre-scale,
head bone 1.75 m, bind pose proven in that game). Clips ride beside it in an
anim-only carrier built from the FBX libraries on the M1 Ultra.
The peds cannot round-trip through Blender: they encode metre scale as a node
scale of 0.01 on mixamorig*:Hips with child bones in centimetres, and Blender
bones carry no rest scale, so the glTF importer silently drops it — the rig is
exploded on import (LeftToe_End 96 m below the floor) before any merge happens.
So merging clips onto the ped (PLAN3D 5-D.1) is not viable; we ship the ped
untouched and retarget rotation-only clips onto it at runtime, the same shape
90sDJsim already uses for peds/idle.glb + peds/walk.glb.
