# Incoprea Theory, Volume XXI — 99 theories by mechanism

Built 30 October 2026. **Entry page: `loggia.html`.** There is no `index.html`.

Fifteen volumes sorted theories by field. This one sorts them by mechanism: nine families of causal
shape, eleven instances each. The claim is that the families transfer across disciplines.

## Format

Claim, mechanism, one prediction, refutation. The shortest format in the series, because the point is
the shape of the argument rather than the detail of the field.
