Implements THE WORLD CONTRACT (TECH.md) in web/js/world/; drop-in for the stub. boot.js now runs this on C's L2_esophagus (3600u, hash cefc4f83), zero console errors. - spline.js: centreline + arclength LUTs + parallel-transport frames + radius law + peristalsis phase + project() + hash(). No three.js import, so qa can run its 14-assertion selfcheck headless. - curviness is solved from a curvature budget, not authored as an amplitude: the pinch guard caught the tube folding through itself on a wide+curvy join (turn radius 9.9 vs tube radius 17.2). C can no longer author a pinch. - peristalsis: global OMEGA, k(s) = OMEGA/flow(s), phase K(s) = integral k ds. A crest therefore travels at exactly the local flow speed, so "surf the crest" == "ride the current". Esophagus wave amp 0.9 -> 1.4 (measured): moves wallRho for Lane B. - tube.js: chunked streaming, seams aligned to biome joins, arenas own their s-span. - arena.js: displaced icosphere shells v0 (three's polyhedron detail is 20*(detail+1)^2, not 20*4^detail — 720 tris was far too coarse); fog sized to the room, since biome fog tuned for 100u corridors renders C's 360u acid sea as a black rectangle. - index.js: prefers assets.texture() over get() (get returns raw JSON a shader can't eat), plus an explicit slug map — D's wall_smallint_a vs biome id small_intestine would miss silently forever under the assets-optional law. Measured (C's real L2 + D's real pack, 1920x1080, renderer.info): 8 draws worst frame (budget 150), 74k tris (500k), no geometry leak across a full sweep, <120ms load, pinch ratio 3.32. fps not claimed — the screenshot pane runs tabs hidden, pausing rAF.

// world/flycam.js (Lane A) — `?fly=1` noclip inspection camera.

|
// Owed to the other lanes per LANE_A_WORLD.md: a way to look at the canal without Lane B's
|
|
// player existing. True noclip (free 6DOF, ignores world.collide) — it is a debug tool, not
|
|
// a preview of arena-mode flight; Lane B owns how the ship actually feels.

// Not wired into boot.js yet: boot owns the camera and `?fly=1` currently drives a rail cam.

// The exact patch is offered in LANE_A_NOTES.md §-> Lane F.
