Verdict: shipped, not killed. The R7 park reason ("touches shared materials") is a non-blocker under
R16's measurement-over-brief standard: the gum-tree billboard material is B-owned (furniture.js), so
this is entirely Lane B -- no C/E material seam. Verified fresh Chromium seed 20261990.
- New web/js/world/wind.js: shared uniforms (uWindTime/uWindAmp) + applyWind(material) (onBeforeCompile
vertex patch: top-weighted horizontal sway, per-instance world-position phase, USE_INSTANCING-guarded)
+ updateWind(dt,intensity). furniture.js applies it to the tree material; weather.js drives it from
update(dt) (base breeze 0.05 clear -> 0.05+intensity*0.30 ~0.35 rain gusts).
- Trees only. Awnings excluded by MEASUREMENT: rigid posted-verandah box slabs don't flutter (fabric
canopy ripple = separate v3.3, shares the rigid awning InstancedMesh today).
- Byte-identical when weather off (the covenant): updateWind runs only inside weather.update, and the
weather system isn't constructed under ?weather=0 / ?classic=1 -> uWindAmp stays 0 -> sin(...)*0.0==0.0
-> identical vertices. Proven: amp=0 two times = 0/180000 px differ; ?weather=0 boot = 0 tree-motion px;
?classic=1 = amp 0, trees render, 0 errors. No plan/fetch/rng change -> F's classic gate untouched.
- Sway works: rain amp 0.305 moves ~14100/180000 region px over 0.8s (exaggerated 2.5 -> 101k); trees
render clean, no glitch. ~0 draws (ALU ops in the existing tree InstancedMesh vertex program), 0 errors.
-> Lane F (B->F handshake): SWAY SHIPPED. In old frames under the default boot; ?classic=1/?weather=0
sway-free + byte-identical. Procedural (no asset -> E has nothing to do).

Consumes the two orphaned street GLBs via the use-if-ready furniture path (fail-soft; ?noassets →
primitives, 0 network).
- Bins: genuinely sparse (~1/block, s+=78m, seeded side), decoupled from benches — country town not
a mall. GLB on its 0.57x0.68 footprint.
- Bus shelters ON THE STREET GRAPH (future tram/bus stops): deterministic rule = midpoint of every
MAIN edge with hashEdge(id)%3===0, road-side footpath by the kerb, long axis along the edge, open
front to road -> 1-3/town (2 in seed 20261990). Solid oriented-rect collider (furniture now returns
colliders; chunks.js merges them into getColliders) -> walk-into-it is blocked. Exported
busShelterStops(plan) -> [{edgeId,x,z,yaw}] as the stop-list contract for the vehicle loop.
- Perf: worst view WITH rig-fleet citizens 94k tris / 148 draws (<=200k / <=300, big margin);
deterministic; all-flags-on (winmap+dig+roster) composes clean, 0 errors. street_bin GLB is 3k tris
-> flagged to Lane E as a decimation candidate (bounded by the sparse cadence for now).

- B1: per-shop closed-facade visuals — dark windows + red CLOSED plate + door tooltip, batched via a
per-vertex aHours attr + two shared shaders + one uHour/uNight uniform pair on a procity:segment
event (facade atlas untouched, no per-shop materials, no per-frame poll). 22:00 → only the openLate
video shop lit, all others CLOSED; ~200 draws worst-view with citizens.
- B2: the shots 'letterbox' was camera-jammed-into-a-wall poses, not a composer bug (composer proven
correctly sized headless). Reframed street_noon/arcade/warehouse to look down a street
(streetViewPose), added the 3 missing bookmarks, night_neon now frames the lit video shop amid
CLOSED neighbours, + a defensive composer resize. shots.py: 10 un-letterboxed shots, 0 errors.
- B3: furniture GLB use-if-ready upgrade (bench + food_cart, sit on their footprints) + novelty_record
placed at record stores. novelty_record GLB is 26.5k tris (5x glb_law) → stays low-poly primitive
until Lane E decimates it; ?noassets verified 0 network.
qa.sh --strict GREEN (4/4).
