Replaces the skip stub with the checks Lane A's header asked for — every GLB
loads, is metre-scale with height on +Y, and keeps the nodes other lanes query
by name — plus anchor world-position and the garden bed's three damage states.
This catches what the Blender side structurally cannot: Blender exports
Z-up->Y-up and imports Y-up->Z-up, so a broken export_yup round-trips green.
A native glTF reader is the only thing that can prove the file.
GLTFLoader is imported dynamically on purpose. Three.js addons import the bare
specifier `three`, no page in the repo has an importmap yet, and selftest.html
turns an un-importable lane module into a hard FAIL — so a static import would
redden Lane A's merge gate over a harness gap rather than a real defect. It
skips with the fix instead, and lights up by itself once the importmap lands.
Verified behind a temporary probe first: 36/36 pass. Need logged in THREADS.

selftest.html only imports; each lane owns js/tests/<letter>.test.js. Five lanes
sharing one selftest.html would be the single guaranteed merge conflict in the
repo, so the stubs are pre-created with each lane's PLAN3D asserts written into
the header.
No rAF anywhere: it's throttled in a hidden tab, so a rAF-driven selftest would
pass only while you watch it. fixedLoop() drives time instead.
Lane A's suite covers the §5-A acceptance criteria, including "camera never
clips through house" — stated as the underlying invariant (no solid between the
player's head and the camera) so it survives Lane E swapping the house GLB.

The yard's meshes are placeholders; its layout is not. Anchor positions, ground
heights, the garden rect and the sun direction are what the other lanes build
against, so Lane E's GLBs drop into named slots without anyone re-deriving them.
Sun sits in the north (Australian yard), which puts the house's yard-facing wall
in permanent backlight. That's correct, but the fascia line carries three of the
seven anchors, so sky fill is turned up to keep it readable rather than a void.
Camera collision resolves toward the geometry, not away from it: clamping up to
a comfort distance after the raycast is what put the camera 17cm inside the
north wall. Ground is handled by heightAt() instead of a raycast — exact, can't
be tunnelled, and free.
main.js runs a fixed-dt accumulator so sim modules only ever see FIXED_DT. That
is what lets selftest fast-forward a 90s storm and get the numbers the player
got. Nothing auto-runs on import; index.html calls boot().

Types, tuning constants ported from the prototype, a seeded PRNG and Emitter,
plus checkContract() — the tripwire that catches a lane drifting from its
interface at merge time instead of three lanes later.
createStubWind() ports the prototype's gust shape (telegraph 1.5s, ramp 0.8s,
hold 1.7s, fade 1.0s) so B and D can develop before Lane C lands weather.js.
Its schedule is precomputed at construction, which keeps sample() pure in t —
the selftest samples out of order and must get the same answer.
