# golden 基线换代辅助（呈现类改动批专用；含棋盘与菜单全屏两种基线路径）。
# 权限口径（Q6）：呈现类改动批内 agent 自行换代+提交说明**强制写明触发原因**；数值/逻辑批禁碰。
# 前置条件（Q5/S3）：素材必须齐盘（本脚本逐项守卫，缺位即拒跑退出 1=基线禁锚回退态；
# 缺位时先拷主区素材+导入边车再跑）。
# 模式：
#   --menu：shot_probe 启动态菜单整屏帧 → game/tests/golden/menu_boot.png。
#     全屏基线可行性前置已验证：菜单连续帧差 0.0000%/max_diff=0（光柱为
#     程序生成静态贴片、零动画着色器，全屏基线不抖动）；采集确定性=探针隔离档（无断点+出厂
#     设置 1280×800），与 render_gate 的 shot_menu 对比段同源同帧。
#   缺省（棋盘）：board_shot_probe 抓 L1-L3 整屏帧+board_meta.json → golden_board_crop.py
#     按 meta 取样坐标裁棋盘区（禁硬编码像素）→ 覆盖 game/tests/golden/ 三张基线。
# 过程截图落 mktemp 临时区即弃（Q2），只有基线产物入库。
# 用法: tools/golden_baseline_refresh.sh [game目录] [--menu]   触发原因写进当批提交说明（强制）。
