Quality Gate / Quality Gate (pull_request) Successful in 6m55s
New visual test site under game/world/sites: flat sandy floor at -40 m, calm surface at 0 m, fixed daytime sun ahead of and above the submarine. Light shafts come from a shadow-only surface occluder whose alpha-scissor ripples open only inside a pool a few tens of metres ahead; a subtractive FogVolume cancels the global volumetric fog above the water, and an unshaded ceiling mesh shows the lit underside of the surface inside that pool. A composed world (sunlit_shallows_world.tscn) mounts the submarine, cockpit and camera rig in it, with the projectors kept out of the fog. Cockpit: the porthole glass moves to its own render layer with a rougher material and the porthole fill light excludes that layer, so interior lamps no longer mirror as hard specular points. Quality gate: new integration suite for the site (42 checks), three glass assertions in the foundation suite, and the Input-access architecture rule now matches both path separators so the gate runs on Windows. project.godot raises the volumetric fog froxel grid to 128 so the shafts stay readable.
