 - Keep the existing rail placement and interaction model for the DB switcher.
 - Widen the visible DB switcher to a predictable default operator range and ensure the currently active DB remains selectable even when it falls outside the default range.
 
-## Planned Implementation
+## Implemented Slice
 
-1. Add a shared frontend helper that returns DB labels for the switcher.
-2. Default the visible range to `db0` through `db15`.
-3. If the active DB falls outside that range, inject it into the visible list and keep the options numerically ordered.
-4. Cover the helper with focused Vitest cases.
-5. Update shared frontend and QA docs so runbooks no longer imply a four-item-only DB switcher.
