A small machine.
An open experiment.

What’s in the release

• The current exploration: variable-height architecture, forgiving jumps, a short falling reset and terminal-driven crossing reconstruction.
• The 40,994-parameter room model and 353-parameter composition ranker, with manifests and hashes.
• The room-design lab, authored data generators, training scripts and held-out comparisons.
• The shared movement controller, bounded physics verification and labelled fallbacks.
• A standalone demo and checks that run without training or paid model calls.

See the archive README for training requirements and individual checks. Training is optional; the selected checkpoints are included.

What the results establish

The room model has not demonstrated better composition than procedural generation. The crossing ranker approximates an authored preference rubric and outperforms a simpler additive baseline on the held-out motif comparison. Running the full rubric directly remains a valid, inexpensive alternative.

Physics verification checks a bounded set of simulated controls. Preference labels are synthetic. These results establish neither player enjoyment nor frame-rate guarantees on every device.
