+## Exit criteria
+
+- The feature is complete when the left tab sidebar is gone; tabs switch only via digit keys `1-6` / `[ ]` and a bottom tab strip
+- All tabs render three stable columns at 1/7 : 3/7 : 3/7 (parent | current | preview)
+- The parent pane renders the previous-depth list and is blank (but keeps its 1/7 slot) at depth 0
+- `h`/`l` drill (push) and pop depths on list tabs; `h` is a noop at depth 0
+- `j`/`k` move within the current pane only; focus starts on the current pane
+- Feed depth 0→1→2, MyShows, Discover, Settings (sections→items→editor), Search, and Player all render correctly via the drive harness
+- `bun run build` passes and `lens_diagnostics` (mode=all) reports zero errors
+- The bottom status bar shows active tab + depth + counts, selection count, now-playing, and the tab strip
