## API Definition

```python

## Import Surface

- standard library: `import simplecadapi as scad` then `scad.std.chain.make_roller_chain_sprocket_rsolid(...)`; direct submodule import: `from simplecadapi.std.chain import make_roller_chain_sprocket_rsolid`

## Description

Create a roller-chain sprocket from tooth count, chain pitch, roller diameter, and tooth-plate thickness. The pitch radius follows the regular pitch polygon. Circular roller seats are cut at every pitch point and opened through the engineering outside-diameter envelope.

The result preserves assembly-level engagement dimensions. Manufacturing release still requires the selected chain standard's permitted tooth-form range, tooth width, hub, material, heat treatment, runout, and supplier checks.
