+
+## Implementation report
+
+Archived registry-only Workers no longer render as Console links.
+
+- Added shared `canOpenWorkerConsole` helper that rejects `state: archived` and `implementation.kind: backend_worker_registry`.
+- Sidebar renders archived Workers as disabled readonly rows instead of anchors.
+- Workers page shows `Archived` instead of `Open Console` for archived Workers.
+- Added unit coverage for live vs archived Console availability.
+
+Validation:
+- cd web/workspace && deno task check
+- cd web/workspace && deno task test
+- git diff --check
+- nix build .#yoi --no-link
