r"""golden_compare.py — C 档黄金图对比（呈现层测试分级·渲染闸周期件）。
|
||
|
||
用法: python tools/golden_compare.py <黄金图目录> <新截图目录> [屏清单...]
|
||
默认屏清单 = shot_menu.png shot_camp.png shot_level.png shot_battle.png。
|
||
|
||
判据（容差口径，v1 冻结）:
|
||
① 四屏存在且尺寸一致（与黄金图逐屏比对）;
|
||
② 逐像素灰度差 >16 的像素占比 ≤2%（抗锯齿/微噪声容差带——结构级变化必超带）;
|
||
③ changed 占比 >2% 即 FAIL（视觉回归信号——逐屏列差异热区提示）。
|
||
基准冻结于 v3.5 视觉落码+营地终稿+分辨率案甲后;资产升档换代时显式重制基准。
|
||
退出码: 0 = 全过 / 1 = 有失败。
