"""parity_anchor.py — 迭代27重构「逐位一致对拍」锚工具（需求卡片-代码架构技术债修复批 §7 V1 核心验收）
|
||||
|
||||
载体 = adventure_monte_carlo.gd 同种子批量完整局（SceneTree headless，自持 ConfigDB，零渲染）。
|
||||
三变体钉死（种子面错开，覆盖 base / 同调账 / 商店-GP 账三类 T2/T3 重构面）：
|
||||
base : -- 20 71000 both min off off off
|
||||
attune : -- 20 72000 both min on off off
|
||||
shop : -- 20 73000 both min off on off
|
||||
|
||||
锚双面：
|
||||
A. RUNSUM 逐行块（stdout 局级摘要面，字符串列表原样入库 anchor.json——红灯时可打印首条差异行）；
|
||||
B. playtest JSONL 全事件流（剔除带墙钟的 session/diagnosis 两类行；文件名本身带时间戳不入比对面）。
|
||||
比对口径 = 字节级逐位一致（同引擎二进制+同种子确定性，冻结前已实测两跑全同）。
|
||||
原始面不入库（体量 MB 级）：红灯取证用 dump 模式对重构前后各落一份原始数据再 diff——
|
||||
旧提交随时可重生成同字节原始面（确定性保证），锚只存 sha256 清单。
|
||||
|
||||
用法:
|
||||
python tools/parity_anchor.py freeze # 冻结锚（重构前基线，写入 game/tests/evidence/parity/anchor.json）
|
||||
python tools/parity_anchor.py check # 对拍：重跑同参批，与锚逐位比对（全同退出 0，差异退出 1 并打印首差异）
|
||||
python tools/parity_anchor.py dump --out DIR # 只跑批落原始面到 DIR（红灯取证）
|
||||
可选 --variants base,attune,shop / --quick（只跑 base）
