 The clip has an understandable beginning, decision, and consequence. It does not
 depend on a voiceover to prove that the simulation is real.
 
+**Status: complete.** `F11` reloads the fixed authored start and runs one
+cinematic pantry-crisis story: a brief valley establishment, the empty pantry
+and worried villager, a trusted helper's real finite-resource trip, visible
+carrying, deposit, and physical recovery. Four short cardless captions fade over
+the world while the camera hands off from the pantry to the helper. The same
+withdrawal, consumption, extraction, and deposit records drive the need and its
+resolution. `tools/validate_pantry_crisis_demo.gd` verifies that the unassisted
