"Waste" That Works by Design
■ Non-function as function The "Hawaii trip / lucky item: energy drink" on Hakobukun's display carries no practical information. Yet Oshiro Aina laughs. What works isn't the content — it's the fact that something happened, addressed to her. Not the correctness of the output but its arrival is what heals.
■ Fatigue comes from absent stimulus Continuous work in enclosed spaces carries a weight separate from labor. The hours in which nothing happens become the load. Hakobukun doesn't grasp that Oshiro is tired — image recognition detected "late at night, alone, on a phone" and triggered a play pattern. If it lands as empathy, that suffices.
■ Conclusion: Playfulness is bandwidth, not decoration What makes a closed corridor habitable is the lightness outside efficiency metrics. KPIs measure delivery counts; what decides whether staff stay is whether anything light happened that day. Returning nonsense at the right moment — small cost, disproportionate effect.
