# VERTICAL SLICE - NOT FOR PRODUCTION
# Date: 2026-09-19
# 棋盘板形统计探针（清图支配性对账重跑批取数工具——判式"实测板形"口径的数据源）：
# 对 board_gen.tres 每行 (L, D) 生成 N 张板，统计幸存雷数 |M| 与安全格数 |S|
# 的均值 / 最小 / 最大（"先布后删"后的落地值——名义值 density×(W×H−9) 不含删除段）。
# 只读诊断，零游戏代码改动；装载面与冒险扫描工具同源（config_db.load_tables）。
# 运行：Godot_console.exe --headless --path . --script res://smoke/board_stat_probe.gd -- [N] [seed0]
