# ---------- 11. CI-Workflows 大版本指针完整性（供应链，红队 #6-A / ADR-0016 决策 3）----------
# 全部业务仓 gate 引用 CI-Workflows@v1 浮动指针；release-tags ruleset 的 admin bypass
# 使指针可被强移（改变所有业务仓实际执行的 CI 内容）。声明不变式（CI-Workflows README
# 版本策略）：vN 恒指向最高 vN.x.y 的 commit。本节每日校验——admin 强移指针 24h 内检出，
# 不可见通道变可检测。附注 tag 指向 tag 对象（非 commit），须解引用后比对。
