LIMITATIONS

Known limitations

- **A collapsed workspace group does not scroll.** Its rows are not mounted, and dsh exposes no public way to expand a group, so the switch happens but the target row stays out of sight. The workspace holding the current session is kept expanded by dsh itself, so `↑`/`↓` are unaffected. - **A rail-collapsed sidebar does not scroll** for the same reason: the tree is not mounted. The switch still happens. - **"In one list" mode** has no workspace sections, but `←`/`→` still walk the controller's workspace order, so the list may appear to jump between sections. - **Scrolling is best effort.** Any lookup failure is swallowed: the selection has already moved, and a missing row must never turn into a wrong one. - **Snapshot fields are pre-stable.** `sessions` and `workspaces` snapshot shapes are pre-stable — the tested host releases are exactly the `engines.dsh` whitelist (`engines.dsh: 0.1.0-rc.2 || 0.1.0-rc.3 || 0.1.0-rc.6 || 0.1.0-rc.7 || 0.1.0-rc.8 || 0.1.1-rc.1 || 0.1.1-rc.2 || 0.1.2-rc.1 || 0.1.5-rc.1 || 0.1.5-rc.2 || 0.1.5-rc.3 || 0.1.7-rc.1 || 0.1.7-rc.2 || 0.2.0-rc.1 || 0.2.0-rc.2 || 0.2.1-rc.1 || 0.2.1-rc.2 || 0.2.1-rc.3 || 0.2.1-rc.4`). If a dsh upgrade changes them, `src/client/navigate.ts` and `src/client/apply.ts` are the only files to revisit; a host that exposes neither switching API leaves the plugin inert rather than failing the page.
