        "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."

        "zh": "在 ChatGPT 网页版以 GPT-5.5 Pro（开启 Extended Pro）一次生成；本页为修复版（改 2 行）。问题一：发条与游丝用 createSpiralTube 构建（760 行），管线段数写成 Math.max(96, turns * 38)，turns 为 5.8 / 6.4 时算出 220.4 / 243.2 的小数段数。修复前：TubeGeometry 末尾会以该段数作下标取 Frenet 帧 frames.normals[220.4]，得到 undefined 后读取 .x 抛 TypeError，初始化中断，页面卡在「Assembling jeweled movement...」加载遮罩永不消失。原因：模型把管线段数当连续值传入，未取整。改为 Math.round(turns * 38) 后段数为整数，场景正常加载、遮罩按时隐藏。问题二：场景中心有一团异常刺眼的辉光，几乎把整块表盘糊成纯白，什么都看不清，放大观察时尤其严重。原因：UnrealBloomPass（340 行）阈值过低（threshold 0.18）且强度偏高（strength 0.72），叠加 ACES 色调映射与那盏强度 96 的主聚光灯打在抛光夹板上的近白高光，几乎所有金属高光与夜光都被纳入泛光并扩散成一大团过曝白光。实测仅把阈值/强度收敛仍不够——近距离时抛光中心板的高光依旧被放大成亮雾。为保护测试者的眼睛、避免对光敏性癫痫人群造成风险，直接关闭 bloom（strength 设为 0）：机芯、齿轮、指针、夹板恢复清晰锐利，夜光时标仍靠材质自发光正常显示。",
        "en": "Generated in one shot in the ChatGPT web app on GPT-5.5 Pro (Extended Pro enabled); fixed build (2 lines changed). Bug 1: 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. Bug 2: an abnormally blinding glow fills the center of the scene, washing the whole dial to pure white so nothing is legible, and it is worst when zoomed in. Cause: UnrealBloomPass (line 340) used too low a threshold (0.18) and a high strength (0.72), which together with ACES tone mapping and the near-white specular the intensity-96 key spotlight casts on the polished plate pulled nearly every metallic highlight and lume surface into the bloom and spread it into one big over-exposed white blob. Merely lowering the threshold/strength was not enough — up close the polished center plate's highlight still blew out into a glowing haze. To protect testers' eyes and avoid any risk to people with photosensitive epilepsy, the bloom was disabled outright (strength set to 0): the movement, gears, hands and bridges are crisp again, and the lume markers still read via their emissive material."
