# VERTICAL SLICE - NOT FOR PRODUCTION
# 判定端 tools/balance_verifier.py 的数据源，本文件零判定逻辑
# 两段一次采集，stdout 以「VJSON 」前缀行出机器读 JSON（其余行为人读进度/摘要）：
#   adventure 段 全冒险连探基线（run_adventure 零永久强化）× 双画像 × na——止步分布、败退节点
#                （摘要 defeat 明细 + 末场战斗敌方名）与逐关条件关卡完成率派生源；inject 档行带
#                inject_tag/override（flat 三键）
#   campaign 段  营地循环战役 × 双画像 × k 局——SaveManager 隔离档 + MetaProgression 真实账本：
#                逐局 hero_override() 注入 → 冒险 → settle_adventure 入账 → 花费策略买锻造，
#                回答「累计几次冒险成功后下一关可过」（元进度换算率标定的模拟读数源）
# 运行：Godot_console.exe --headless --path . --script res://sim/verifier_batch.gd -- [k=v ...]
#   na=40(基线冒险局数) k=40(战役局数) seed0=8000
#   only=adventure,campaign(缺省全段) spend=hp_first|atk_first|armor_first(锻造花费优先序)
#   inject=max_hp:3,atk:1(冒险段 flat 注入档——三键 {max_hp, atk, armor_class}，缺省全零白板；
#   换算率标定用：每档与白板同种子流配对，逐关条件关卡完成率差 = 该档的带平移量实测)
# 种子纪律：unique 逐局独立（掷点测量修复批 A 案——seed0 + 全局游标，每掷点恰消费一次）。
#           同 seed0 跨档复用 = 配对读数（同序种子流——分析侧按种子配对消方差）。
# 日志合规：全段共享 playtest_logger 会话（与真人试玩同日志），分析工具可直接消费。
# 存档红线：战役档用 user://verifier_campaign_<画像>.json 隔离路径，段首清陈旧段尾清理——
#           绝不碰 user://save.json（与 smoke 存档隔离纪律同源）。
