# Ideator Wave 20 — Sept 19, 2026 (Cell Elements)

**5 elemental ideas**: stone, water, fire, air, metal.

## 1. quilt-cell-stone — Solid
- Schema: `hardness`, `weight`, `endurance`
- Cells harden; last long
- **Stone is a cell-state.**

## 2. quilt-cell-water — Liquid
- Schema: `fluidity`, `purity`, `current`
- Cells flow, adapt
- **The substrate has rivers.**

## 3. quilt-cell-fire — Combustion
- Schema: `temperature`, `fuel`, `ash`
- Cells transform; heat is witnessed by neighbors
- **The substrate has fire.**

## 4. quilt-cell-air — Gas
- Schema: `altitude`, `humidity`, `pressure`
- Cells drift; carry messages
- **The substrate has wind.**

## 5. quilt-cell-metal — Conductor
- Schema: `conductivity`, `purity`, `magnetism`
- Cells conduct witnesses
- **The substrate has circuits.**

## Cross-cutting

All 5 ideas introduce **classical elements** to cells. The substrate now has:
- **Solid** (stone)
- **Liquid** (water)
- **Plasma** (fire)
- **Gas** (air)
- **Conductor** (metal)

The canon is becoming **matter**.
