The Science Story

ludoSpring proves that game design is rigorous science — not an aesthetic category but an interaction architecture governed by measurable laws. Fitts’s law predicts click time. Hick’s law predicts decision time. Flow theory discriminates quality. These are not opinions; they are published, validated, reproducible results.

The deeper insight: the provenance machinery built for game item tracking (chain-of-custody, attribution, fraud detection) is structurally identical to the provenance needed for biological samples, medical records, and scientific data. >80% structural similarity across domains. The same Provenance Trio that tracks a magic sword tracks a soil sample tracks a patient record.

What the Constraint Revealed

Building game mechanics from validated HCI models (instead of intuition) created a natural bridge to other domains. Engagement metrics that predict player retention also predict science session quality. The fraud detectors built for game item provenance detect the same structural patterns in clinical sample chains. The constraint of “every game mechanic must trace to a paper” eliminated magic numbers and produced mechanistically grounded design.

The Doom raycaster exists not as entertainment but as validation: can the same GPU pipeline (barraCuda) that runs lattice QCD also render real-time 3D at 110x the target framerate? Yes — and it uses the same WGSL shaders.
