 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.

 - **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.
