 ## Contract / 契约
 
-`scan_public_boundary` still enumerates the full requested tree, including Git-owned
-files inside otherwise pruned directories. Its existing owner decides which
-local-private files to exclude **before** submitting any reads. Eligible files are
-reopened on every request. The filesystem adapter overlaps at most eight reads and
-returns them in the original sorted order; it does not cache scan results or
-change leak rules, policy, Git ownership, counts, or error handling.
-
-`scan_public_boundary` 仍扫描完整的指定目录，包括通常会被剪枝、但属于 Git
-版本控制的文件。既有扫描 owner 在提交读取之前排除未跟踪的本地私有文件。
-每次请求重新打开所有符合条件的文件；文件系统适配器最多并发读取八个文件，
-按原来的排序返回结果，不缓存扫描结果，不改变泄漏规则、策略、Git 所有权、
-计数及错误处理。
+Ordinary `status`, quota decisions, initial planning and native Turn/heartbeat
+launch or checkpoint continuation **defer** repository public-boundary scanning.
+They still re-read current execution authority: Stop, pause, compute, Goal/Agent,
+source, claim/lease and the original receipt/action/settlement binding. Deferral
+does not certify public safety. The existing status checks explicitly say
+`public boundary scan deferred`; no execution setting or permission bypass is
+introduced.
+
+普通 `status`、quota 决策、首次规划、原生 Turn/heartbeat 启动及 checkpoint 接续
+默认**推迟**仓库公共边界扫描，仍复查 Stop、暂停、compute、Goal/Agent、source、
+claim/lease 和原 receipt/action/settlement 绑定。推迟不等于公开安全；既有状态检查
+明确显示 `public boundary scan deferred`，没有新增执行配置或权限绕过。
+
+Explicit `loopx check --scan-path <outgoing-file-or-directory>` and the existing
+premerge check scan selected outgoing content. Repeat `--scan-path` for multiple
+files, including a saved diff, attachment or draft body. Premerge selects existing
+changed files. This is not a universal outbound interceptor: generated-text
+presentation guards retain their separate existing owner and policy; arbitrary
+uploads/messages are not automatically covered by a successful file check.
+
+显式 `loopx check --scan-path <拟外发文件或目录>` 与既有 premerge 检查选定外发内容。
+多个文件可重复传 `--scan-path`，也可选择已保存的 diff、附件或正文草稿；premerge
+选择当前存在的变更文件。这不是统一外发拦截器：生成文本的 presentation guard
+保留既有独立 owner 和策略，任意上传或消息不因文件检查成功而自动获得覆盖。
+
+The existing scanner retains all rule locations in `hits`. Literal credentials,
+private source/path content and non-public registries remain blockers in
+`blocking_hits`. A private IP alone is ambiguous: it remains a located warning,
+as do existing credential environment/example references. These warnings do not
+block the check and are labelled **completed with warnings**, never clean. This
+is heuristic assistance, not proof that arbitrary content is safe or secret.
+
+既有扫描器在 `hits` 保留全部规则定位，`blocking_hits` 保留字面凭据、私有来源/
+路径内容及非公开 registry 等阻断项。单独内网 IP 属于含糊信号，仍显示带位置的
+提示；原有凭据环境变量/示例引用同样提示。提示不阻断检查，显示为
+**completed with warnings**，不称 clean。规则是辅助检查，不能证明任意内容安全
+或含有秘密。
+
+Missing roots, unreadable directories/files and undecodable UTF-8 fail the check.
+Explicit private-file/directory selection cannot hide behind Git ignore or
+directory pruning; tracked private state is also blocked. The existing opt-in
+tracked-document-URL policy still applies to otherwise public files, and is
+re-read on each check; it does not authorize private-state export. Untargeted,
+untracked private state stays excluded **before** file reads.
+
+缺失根目录、不可列目录、不可读文件及无法解码的 UTF-8 均使检查失败。显式选择
+私有文件/目录不能靠 Git ignore 或目录剪枝得到空扫描成功；已跟踪私有状态也阻断。
+原有显式 tracked-document-URL 策略仍适用于其他公开文件，每次检查重新读取；它
+不授权私有状态导出。未被选作外发目标的未跟踪私有状态仍在读取**之前**排除。
+
+`scan_public_boundary` enumerates the full selected tree, including Git-owned
+files inside otherwise pruned directories. Eligible files are reopened on each
+explicit check. The filesystem adapter overlaps at most eight reads and returns
+them in sorted order; it caches no content or result.
+
+`scan_public_boundary` 遍历完整指定树，包括通常剪枝目录中的 Git 文件。显式检查

 The bound is a file-count bound, not a byte-budget or atomic filesystem snapshot.

+An unreadable or undecodable input is not downgraded to a clean scan. Workers
 only read UTF-8 bytes: traversal, policy, classification and state writes are not
 delegated to them.
 
 限制针对待处理文件数量，不是字节预算，也不承诺原子文件系统快照。

 ## Placement / 实现边界
 
-The change is a Python filesystem adapter beneath the existing Python scan owner.
-It does not add a second control-plane decision source. Moving the scan policy or
-completion/deadline authority to a new owner is out of scope; the existing
-TypeScript transaction and settlement owners remain unchanged. This bounded I/O
-repair need not wait for the larger TypeScript migration.
+Filesystem classification and explicit check reporting remain in the existing
+Python scan/check owner and bounded reader. There is no second policy store or
+control-plane decision source. Existing TypeScript admission, transaction,
+completion/deadline and settlement owners remain unchanged.
 
-这次改动是既有 Python 扫描 owner 下面的文件系统适配器，不新增平行控制面决策源。
-不迁移扫描策略，也不改变完成、时限或结算权威；既有 TypeScript 事务及结算
-owner 保持不变。这个有界 I/O 修复不以前置完成整个 TS 重构为条件。
+文件系统分类及显式检查报告保留在既有 Python scan/check owner 和有界 reader，
+没有第二份策略存储或平行控制面决策源；既有 TypeScript 准入、事务、完成、
+时限和结算 owner 不变。
 
 ## User paths / 用户入口
 
-CLI checks and quota preparation reuse the same scan and response projection.
-There is no new setting, CLI flag, frontend control or Lark command. The existing
-frontend status hot path still explicitly defers the repository scan; it must not
-be reported as a completed public-boundary check. Managed/Lark consumers keep the
-same quota gate rather than a separate optimization-specific result.
+CLI checks run the scanner; operational CLI, managed hosts and Lark use the same
+status owner with scanning deferred by default. The frontend status path already
+defers it. There is no new setting, CLI flag, frontend control or Lark command.
+The compact status projection keeps the deferred check text rather than adding
+repository scan bodies to every ordinary response.
 
-CLI 检查及 quota 准备继续复用同一扫描和响应投影，没有新增配置、CLI 参数、
-前端控件或 Lark 命令。既有前端状态热路径仍明确推迟仓库扫描，不能冒充已完成
-公共边界检查。Managed/Lark 消费者使用原有 quota 门禁，不另建优化专用结果。
+CLI 显式检查执行扫描，运行用 CLI、managed host 与 Lark 复用既有状态 owner，
+默认推迟扫描；前端状态路径此前已推迟。没有新增配置、CLI 参数、前端控件或
+Lark 命令。紧凑状态投影保留 deferred 检查文字，不向每次普通响应加入仓库扫描正文。
 
 Therefore no packaged frontend rebuild or layout change is required. Existing
 status-hot-path regression checks must continue to prove the explicit deferred
