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).

- tram.js: 1 small bus, seeded out-and-back loop on the main-street spine,
door-dwell at each busShelterStops stop, ping-pong at ends. Deterministic,
exactly 2 draws, night headlights via lighting.isNight(). Flag-off identical.
Shell wiring (2 lines) documented for F in LANE_B_NOTES.
- dbg.js: 8 v2 tour bookmarks (16 total) incl. rain_verandah hero shot;
tram_stop now frames the nearest-origin (open) shelter stop.
- weather.js: cap rain gl_PointSize (clamp 2-22px) - near drops are thin
streaks now, not blobs. Rain smoke still GREEN.
- qa.sh --strict GREEN, golden hash frozen, flags-off byte-identical.

New js/world/weather.js + a one-line lighting.setSky(). Seeded per citySeed (weatherFor):
~57/24/19% clear/overcast/rain over 400 seeds, deterministic. Rain = ONE draw (camera-following
Points + procedural streak/fall/wind shader) + wet ground (roughness/darken on shared ground mats,
restored on dispose) + matching rainy sky dome via lighting.setSky. Fully procedural (0 depot fetch).
- Exposes window.PROCITY.weather = { state:'clear'|'overcast'|'rain', intensity:0..1 } for Lane D's
weather-reactive crowds (decision #1). Documented the contract + the exact 3-line shell wiring for F
in LANE_B_NOTES (I don't touch index.html). ?weather=1 seeded (default town rolls clear);
?weather=rain|overcast|clear forces a state for demos/smokes.
- Worst view 141 draws day / 126 night (<=300); composes with ?winmap + night (rain outside a lit
interior-mapped window = the money shot, screenshotted); deterministic; 0 console errors; flag-off
byte-identical (shell never constructs it). Deferred cut line: vertex-shader wind sway on
trees/awnings (touches other lanes' materials) — noted, not done. Tram stretch not attempted.
qa.sh --strict GREEN (5/5).
