# Stage C4. Model: the field

[Back to the Manual](../README.md)

**What it produces:** the model against a sealed model of r/place, where the rooms met; what only the field sees enters as `from-field` hypotheses for stage D. **Model:** `arm.json`. (From the contract's stage table, section 4.)

Status: **finished**.
