+The repository supports source execution through its root `pnpm` scripts. The `pnpm dsh <args...>` launcher runs the complete repository build before launching the source CLI.

 Source users invoke repository scripts rather than an installed `dsh` command. The repository provides no atomic upgrade cutover or preserved staging rollback checkout, and it does not automate the integration or upstream publication of personal source modifications. A future distribution mechanism must justify its ownership of installation and upgrade state, define recovery behavior, and add tests and user documentation without making the source-run path depend on it. Any future publication workflow must isolate one approved feature and obtain explicit approval before its first push and draft PR.
