@@ -51,10 +51,13 @@ Recent decisions affecting current work:
 - 01-02: Use ratatui::crossterm re-export path — crossterm is transitive dep, not direct dep in Cargo.toml
 - 01-02: SIGINT not registered via signal-hook — crossterm key events handle double-press Ctrl+C in Plan 03
 - 01-02: restore_terminal() skips ratatui::restore() — that would call LeaveAlternateScreen (never entered)
+- 01-03: show_goodbye() called after restore_terminal() — terminal must be in cooked mode before println! is safe
+- 01-03: app_config stored in App struct for Phase 2 access — vault_path accessible inside event loop
+- 01-03: Quit prompt cleared on any non-Ctrl+C key — pressing any key dismisses double-press window
