 | 2026-03-21 | P3.2 | Completed | Replaced the floating table picker with a permanent left-rail layout, converted the old selector component into a real page header, and kept the current selection flow intact inside the new reference frame. |

 ### Lessons Learned
 
@@ -95,6 +96,7 @@ It is intentionally implementation-focused:
 - Backdrop and outside-click behavior depend on overlay ownership as much as CSS. If the trigger owns the overlay inside a sticky header subtree, fixed-position assumptions can break; shell-level overlays should be rendered by the shell, not by individual header controls.
 - The `Tables` rewrite is safer when orchestration and rendering are separated early. Keeping loading, persistence, and dialog state in the page host while extracting render-only components makes later layout and interaction changes much lower risk.
 - The `Tables` navigation model needs its own persistent geometry before advanced behaviors land. Converting the selector to a real rail first keeps later search and keyboard work from being tangled up with another structural rewrite.
+- Rail keyboard behavior is easiest to maintain when it works from one deduplicated option order, even if the UI shows multiple sections. Keeping one internal option list avoids separate arrow-key state per section.
