auto_vs_golden.py — M2 auto-vs-golden delta 门(Node 退役授权第三条 · 按品类 · 零 LLM)。

【封存(W-AXIS-V2 波2,2026-07-10)】对照范式建立在 ensure_play_spec 自动 spec 与 tap-targets 驱动器上;
两者已随取证契约退出便宜档验收链(验收权威 = 四门投影 ∧ 测试 agent 真玩)。其使命——Node 退役授权的
「自动 spec 不比金标驱得差」——已随 Node 路退役完结,不改挂测试员(范式不同,无对照意义)。保留代码
供历史复跑;生产链与批跑不再调用,play-spec 生成器窗口期结束后随其一并清理。

对同一款生成产物,在同一份 staged src/ 上先用生产自动 spec(ensure_play_spec)、后用金标 spec
(inject_golden)各驱动一次九门,逐门比过门率。方向单边(承 plan① M2「关键门不得低于金标基线」):
查的是自动 spec 是否比金标**驱得差**(delta<0 退化),不是查自动比金标松——后者对断言同质的
tap-targets 不成立(M1 已把自动 spec 断言加厚到与金标逐字段一致)。

这道门在 tap-targets 覆盖面内鉴别力有限(delta≈0 几必然),诚实定性为「不退化确认 + 逐款驱动器
推断不失效」,非决定性独立闸;Node 退役授权的强证据是 M1 绝对达标 + 002 两路等价(见 U3 三条齐)。

U1 逐门 delta 判据(本段,纯逻辑可单测);U2 同游戏双驱动 play 真跑;U3 三条齐退役授权判定。
