feat: stage 2 real CAD conveyor, hybrid physics drops, mobile policy (WIP)
- CAD pipeline: conveer.FCStd -> FreeCAD headless -> conveyor-web.glb (555KB Draco, 42 named nodes) integrated into main scene; gates and rollers animated from domain state - Domain-driven adapter sorterVisualState.ts; per-SKU visual physics profiles (VISUAL_PHYSICS_ESTIMATE) - Hybrid Rapier physics: kinematic belt travel -> dynamic drop handoff -> verified freeze; shared collider layout (physicsWorldLayout) used by runtime and headless validation sim (physicsDropSim + 13 tests) - Gravity chutes / open roll-cage front redesign (drop tuning in progress: 4/7 routes verified headless) - Premium industrial visual: PBR, ACES, PCFSoft shadows, Lightformer env, UI cleanup behind ?debug=1 - Mobile capability policy: SVG fallback / Mobile Low / full tiers, Telegram WebView forced to SVG, e2e stubs for weak devices - Performance benchmarks cad-light/physics/full pass; stage2 artifacts tsc clean. Physics drop validation for 3 SKU routes still in progress. Co-authored-by: Cursor <cursoragent@cursor.com>

/**
|
||||
* Stage 2 — single source of truth for static physics colliders.
|
||||
*
|
||||
* Pure data (no React, no Rapier): consumed by
|
||||
* - SorterStaticColliders (runtime, @react-three/rapier CuboidColliders);
|
||||
* - physicsDropSim (headless Node validation with rapier3d-compat).
|
||||
*
|
||||
* Geometry contract (visual == collider == domain kinematic surface):
|
||||
* - C/D gravity chutes follow the domain chute line (conveyorNetwork
|
||||
* CHUTE_C/D_ENTRY -> EXIT): from belt edge y=0.66 down to cage front edge
|
||||
* y=0.14 — real gravity-chute pitch ~0.39 rad (smooth coated steel,
|
||||
* friction 0.2), not a gentle ramp where items would stall.
|
||||
* - Cage C/D entry side is OPEN (real roll cages are 3-sided + open front)
|
||||
* with a 40mm sill; the chute deposits items through the open front.
|
||||
* - B drop chute descends from spur end (2.15, 0.70) into the open front of
|
||||
* the B receiver bin (past its low entry lip).
|
||||
* Every collider mirrors VISIBLE scene geometry — no fake guides (§11.6).
