# Incoprea Theory, Volume XVIII — 99 theories by mechanism

Built 30 October 2026. **Entry page: `porch.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.

## Contents

| Path | What |
|---|---|
| `porch.html` | Contents page — the entry point |
| `theories/<slug>.html` | One page per theory (99) |
| `wordpress/<slug>.html` | WordPress fragment per theory |
| `wordpress/theory-index.html` | Contents fragment |
| `MANIFEST.json` | SHA-256 for every file |
| `build/` | Three data files and the renderer |

## Families

- Polar & Sea Ice (11)
- Boreal Forest (11)
- Temperate Forest (11)
- Grassland & Savanna (11)
- Desert & Dryland (11)
- Tropical Rainforest (11)
- Mountain & Alpine (11)
- Freshwater & Wetland (11)
- River & Floodplain (11)
- Coastal & Estuary (11)
- Urban & Built Environment (11)

## 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.
