debris.js: hand-rolled kinematic tumble, drag ∝ speed² so the gust that
spikes a corner is the one that launches the neighbour's bin. Ground bounce
via world.heightAt (contracts.js documents it as ours), sphere-vs-player
knockdown reported to Lane D, sphere-vs-sail-node impulse duck-typed so it
lights up when Lane B exposes nodes and stays silent until then.
skyfx.js: instanced rain that wraps around the camera rather than respawning,
storm sky + procedural cloud dome, lightning, and synthesized WebAudio layers
(wind bed, howl, rain, gust whoosh on the telegraph, rope creak off the worst
corner, flog when one blows). It modulates Lane A's lights and hands them back
on dispose() rather than owning them.
weather_demo.html: graybox bench to drive all three before M0 — mock sail,
storm scrub, 4x, throw-a-crate.
Aligned to contracts.js now that it has landed: relative three imports (there
is no importmap), contracts' rng() instead of a local copy, and storm paths
resolved off import.meta.url — server.py serves the repo root, so an absolute
/world/... would have 404'd at integration.
storm_02: fix the southerly change. contracts.js puts north at -Z and the wind
vector blows toward (cos d, sin d), so the old swing to +2.6 blew toward due
south — a northerly wearing a southerly's name. Now slews to -1.35: a SSW
buster off the open side of the yard, into the house.

Implements the contracts.js wind surface (PLAN3D §4): sample(pos,t) and
gustTelegraph(t), plus storm defs as data.
The prototype scheduled gusts by integrating (wind.gustT += dt). We can't:
sample(pos,t) is called by sail/player/debris/rain at arbitrary t, so gusts
are precomputed into a timeline from a seeded PRNG at load and read from t.
Envelope shape is a faithful port — telegraph 1.5s / ramp 0.8s / hold 1.7s /
fade 1.0s.
Maths lives in weather.core.js with zero imports (no THREE, no DOM, no
Date.now), so the determinism rule is structural and the suite runs in node
without waiting on Lane A's M0.
storm_01_gentle peaks at 11 m/s; storm_02_wildnight sustains 20 m/s and gusts
to 32 (BOM 'destructive'), with the southerly change landing just before the
worst of it — the corners that were slack all storm are the ones that cop it.
15 asserts green: telegraph lead >=1.2s, wind continuity in time and space,
storm JSON validator (incl. 14 deliberately-broken defs it must reject),
determinism, sample-order independence, tree wind shadow.

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.

server.py serves the repo root rather than web/, so the 2D prototype stays
reachable next to the 3D port — you want to flip between the reference
implementation and the thing you're porting without stopping the server.
--selfcheck verifies the tree and prints URLs; no node, no network.
three r175 is copied in from 90sDJsim rather than referenced, so the game has
no runtime dependency on a sibling checkout.

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.
