+## Implementation report
+
+Removed duplicate Workspace Worker `status` from browser-facing Worker summaries.
+
+- `WorkerSummary` now exposes `state` only for Worker state.
+- Backend Worker projections populate only `state`; registry-only Workers remain `state: archived`.
+- Frontend Worker type, sidebar, Workers page, and Console header no longer reference `worker.status`.
+- Runtime/Host/Workdir/protocol statuses are unchanged where they are distinct domain concepts.
+
+Validation:
+- cargo test -q -p yoi-workspace-server
+- cd web/workspace && deno task check
+- cd web/workspace && deno task test
+- cargo test -q
+- git diff --check
+- nix build .#yoi --no-link
