+
+Shared anonymous identity for session telemetry and direct feedback acknowledgement. `getOrCreateAnonymousUserId()` returns a random UUID v4 scoped to one harness home, persisted as the bare line `$DSH_HOME/.userid` (`~/.dsh/.userid` when `DSH_HOME` is unset). The OpenTelemetry backend reports it as Resource `user.id`; `/feedback` includes the same value in its acknowledgement so an operator can correlate a submitted session and user with exported telemetry.
+
+The identity is never derived from the hostname, network address, git remote, or another identifying source. Deleting `.userid` resets the identity on the next process launch. Separate harness homes have separate identities, and the dsh-sdk launcher telemetry intentionally keeps its own unrelated store.
+
+## Storage contract
+
+Reads and writes are synchronous because both boot-time telemetry construction and direct command execution need one API. The result is memoized per resolved file path for the process lifetime. A first writer uses exclusive creation and a concurrent loser adopts the persisted winner; a corrupt file is replaced. Persistence is best-effort, so an unwritable home still receives a process-local UUID rather than blocking telemetry or feedback.
+
+## Composition
+
+This package is a shared library, not a Cordis plugin. Consumers import `getOrCreateAnonymousUserId()` directly. Its invariant companion is intentionally empty because the package owns no event stream or public mutable relation that can be checked without creating the identity as a side effect.
+
+## Model Experience
+
+None, as the identifier is used only in telemetry metadata and a direct human command response; it never enters a model request.
+
+#### KV Cache effect
+
+None; this package never contributes to a model request.
+
+## Known Limitations and Deferred Work
+
+- **No recovery after deletion** — loss mints a new anonymous identity by design; recovery would require stable derivation material that weakens anonymity.
+- **Best-effort concurrency** — a reader landing in the narrow interval between a concurrent process's exclusive create and completed write can use a different in-memory UUID for that run; later launches converge on the persisted value.
+- **No cross-home identity** — different `$DSH_HOME` values cannot be correlated, and this package does not unify the separate dsh-sdk launcher telemetry identity.

+会话遥测与直接反馈确认共用的匿名身份。`getOrCreateAnonymousUserId()` 返回一个限定于单个 harness home 的随机 UUID v4，并以裸行形式持久化到 `$DSH_HOME/.userid`（未设置 `DSH_HOME` 时为 `~/.dsh/.userid`）。OpenTelemetry 后端将其作为 Resource 的 `user.id` 上报；`/feedback` 在确认文本中包含同一个值，以便运维人员将所报告的会话和用户与导出的遥测相关联。
+
+该身份绝不从 hostname、网络地址、git remote 或其他可用于识别身份的来源派生。删除 `.userid` 后，下次启动进程时会重置身份。不同 harness home 拥有不同身份，dsh-sdk launcher telemetry 则刻意使用与此无关的独立存储。
+
+## 存储契约
+
+读写采用同步方式，因为启动时构造遥测和直接执行命令都需要使用同一个 API。结果在进程生命周期内按解析后的文件路径缓存。首个写入方采用独占创建；并发竞争中失败的一方会采用已持久化的胜出值。损坏的文件会被替换。持久化采用 best-effort，因此即使 home 不可写，系统仍会返回进程本地 UUID，而不会阻塞遥测或反馈。
+
+## 组合
+
+本包是共享库，并非 Cordis 插件。消费方直接导入 `getOrCreateAnonymousUserId()`。其不变式伴生插件刻意留空，因为本包既不拥有事件流，也不拥有任何可以在不触发创建身份这一副作用的情况下检查的公开可变关系。
+
+## 模型体验
+
+无，因为该标识符只用于遥测元数据和面向用户的直接命令响应；它绝不会进入模型请求。
+
+#### KV Cache 影响
+
+无；本包绝不会向模型请求贡献任何内容。
+
+## 已知限制与暂缓工作
+
+- **删除后无法恢复**：身份丢失后会按设计生成新的匿名身份；若要恢复身份，就需要稳定的派生材料，这会削弱匿名性。
+- **Best-effort 并发**：如果读取方恰好落在并发进程完成独占创建但尚未写完的狭窄时间窗内，本次运行可能使用不同的内存 UUID；后续启动会收敛到已持久化的值。
+- **没有跨 home 身份**：不同 `$DSH_HOME` 值之间无法关联，本包也不会统一 dsh-sdk launcher telemetry 的独立身份。
