+## End-to-end interaction flows

+`smoke_ui_flows.gd` boots the real scene and verifies, in order:
+
+- inspection opens, then allow and deny both close the panel;
+- a normal radio click sends and spends battery;
+- an emergency hold sends once, spends battery and starts cooldown;
+- Help opens, filters to radio controls and closes;
+- the wand opens at The Joke Shop, then allow and deny close it;
+- returning from the review restores the venue menu.
+
+`smoke_campaign.gd` covers review continue plus checkpoint resume, and
+`smoke_timeline.gd` covers review → timeline → review. These are end-to-end
+scene smokes, not just panel-unit tests.

 ## Remaining audit work
 
 - Player-facing labels are now routed through `content/strings.en.json`; numeric
   values, empty-state clears and debug-only text remain in code by design.
 - Focus/hover/pressed/disabled states and keyboard/gamepad rings are recorded above.
-- Long strings and 0.75×/1.75× HUD scale are covered above.
 - Capture every dialog/button state and run `screen_designs.py compare` plus the pinned judge.
