 ## Consequences
 
-Each bridge parses config atomically, builds its dialect payload, invokes the shared runner and merge logic, maps the decision, and appends `hook/*`. Protocol tests cover every matcher mode and diagnostic, exit-code and codec field, runner plumbing, merge precedence, and audit helper at per-file 100%; bridge tests exercise the library's real load path and pin invalid-config containment. `updatedInput` is parsed but only logged and warned until the [input-rewrite proposal](../../proposed/feature/2026-06-30-pre-tool-input-rewrite.md) lands.
+Each bridge parses config atomically, builds its dialect payload, invokes the shared runner and merge logic, maps the decision, and appends `hook/*`. Protocol tests cover every matcher mode and diagnostic, exit-code and codec field, runner plumbing, merge precedence, and audit helper at per-file 100%; bridge tests exercise the library's load path and pin the exact warning. Keyless ACP snapshots boot both bridges through the real Loader/app path with a valid blocking group before an invalid matcher, then prove the request reaches the replay model and persists no `hook/*` rows, so partial registration cannot hide behind a hand-mounted context. `updatedInput` is parsed but only logged and warned until the [input-rewrite proposal](../../proposed/feature/2026-06-30-pre-tool-input-rewrite.md) lands.

 ## 后果
 
-每个桥接插件以原子方式解析配置、构建方言 payload、调用共享的 runner 与合并逻辑、映射 decision、追加 `hook/*`。协议测试覆盖每种 matcher 模式与诊断、exit-code 与编解码器字段、runner 管道、合并优先级和审计辅助函数，逐文件 100% 覆盖率；桥接插件测试验证库的真实加载路径，并锁定无效配置的隔离行为。`updatedInput` 已解析但仅记录日志并发出警告，直到 [input-rewrite 提案](../../proposed/feature/2026-06-30-pre-tool-input-rewrite.md)落地。
