kind: after

note: Ticket has explicit typed `depends_on` relation to `00001KX6Y2A9Q`. The prerequisite WorkerFilesystemAuthority refactor is currently `inprogress` and establishes the filesystem-authority/workspace-boundary this Ticket builds on. Start only after the prerequisite is approved, merged, and closed or an explicit combined-work decision is made.

note: Dashboard queue routing inspected. This Ticket is concrete but blocked by typed `depends_on` relation to `00001KX6Y2A9Q`, which is currently inprogress. Starting now would conflict with the Worker struct/context/constructor refactor and filesystem-authority boundary. Leave queued and re-route after prerequisite merge/close.


note: Queue review resumed after prerequisite `00001KX6Y2A9Q` closed. `00001KX6WVNPD` was accepted first because it is the smaller embedded no-workdir policy MVP and explicitly does not require WorkspaceBackend migration. This Ticket remains queued due migration-boundary/conflict risk: it removes Worker `workspace_root` and introduces WorkspaceBackend/WorkspaceClient surfaces in the same Worker context/constructor/runtime code that `00001KX6WVNPD` is now changing. Re-route after `00001KX6WVNPD` is reviewed/merged/closed, unless a human explicitly requests a combined branch.
