Record U5 authority checks and independent review

Why: Preserve entrypoint scope, rule consistency and verification limits before delivery.

Evidence: Fixed-diff independent PI review has no blocker; host authority targets and diff checks passed.

Impact: Task metadata only; no broad prose mirror tests added.

 ## 结果与验证（完成后填写）
 
-- 结果：
-- 验证：<结论摘要 PASS/FAIL/SKIP/NOT_RUN 逐项；逐条证据由 make evidence 写入上方证据表>
-- 影响与剩余项：
+- 结果：AGENTS 改为触发式权威路由与必要边界，删除重复的 token/端点说明；明确本地续作与正式准入、同步恢复和分级证据，避免无条件摘要重新阻断 U2/U3。PROJECT 保留稳定组合/验证事实与全部既有主题链接，将动态批准/进度/验收归还主记录。
+- 验证：host 在实现候选 `1b04fd4a0408931bb84c44c2fe692205ff25079f` 检查 diff 与物化后的核心权威目标文件，均通过（SELF receipt 已导入）；独立 fresh PI Review 对规则保留、恢复无循环门禁、证据分级及链接/锚点审查无阻塞项。纯说明/路由变更不新增镜像文本测试、不重复完整套件；最终组合验证仍由 U6 执行。
+- 影响与剩余项：只改两个入口文件。review 私有目录未物化子模块，报告中相关目标存在性以其末尾限制说明为准；host 已在当前物化 checkout 验证核心权威文件存在，既有 proposal 链接未改变。不读取凭据、不运行在线事实刷新。
