        "en": "Generated with GPT-5.5 Pro (Extended Pro enabled); fixed build (1 line changed). Bug: 14 tiles in an 8x2 atlas with only 6 slots drawn in row two, UVs computed from a top-left origin without flipY=false, so the two rows swapped on sampling. Before the fix: grass tops rendered as obsidian (black ground), leaves and sand hit undrawn slots (large black patches), and placed blocks wore each other's textures with inverted-looking colors. Cause: CanvasTexture defaults to flipY=true, mismatching the top-down atlas layout. With flipY=false everything renders correctly."

        "en": "Generated in one shot in the ChatGPT web app on GPT-5.5 Pro (Extended Pro enabled); fixed build (1 line changed). Bug: the mainspring and hairspring are built via createSpiralTube (line 760) with the tube segment count written as Math.max(96, turns * 38), so turns of 5.8 / 6.4 yield fractional counts 220.4 / 243.2. Before the fix: TubeGeometry's trailing generateSegment indexes the Frenet-frame arrays with that count (frames.normals[220.4]), gets undefined and reads .x, throwing a TypeError that aborts init and leaves the page stuck on the 'Assembling jeweled movement...' loading overlay forever. Cause: the model passed the tube segment count as a continuous value without rounding. Changing it to Math.round(turns * 38) makes the count an integer, so the scene loads and the overlay hides on schedule."
