The former #143 flag forced every server-object light onto the D3D dynamic path (1/d attenuation, range x1.5); retail's stationary fixtures use the static calc_point_light curve (0x0059c8b0, Ghidra-verified: f=(1-d/range)*intensity*wrap/d^3 beyond 1m, range=falloff*1.3, per-channel colour clamp) - the dynamic path burned every Facility Hub lamp ~10x hotter than retail at 3m, producing the saturated magenta wash that zebra-striped normal wall geometry into the #176 'stripes/triangles' pattern (VSync-on test + clean captures characterized it as STATIC over-bright content, not flicker/tearing/camera). The shader's static branch already implements the verified curve faithfully (mesh_modern.vert pointContribution - its wrap constants pin LIGHT_POINT_RANGE=0.75), so the whole fix is the registration decision. Site-A lights are all stationary today (AP-44); genuinely moving lights re-earn isDynamic when they exist. Suites green.
