# ControlNet / Conditioning Reading

This starter is annotated reading material and the source of truth for the lab preview. Running anything is optional; the reading goal is to explain the mechanism without hiding behind a framework call.

## Reading focus

Read ControlNet-style conditioning as an extra structural signal path into denoising.

## Annotated sketch

```text
## Control path

```text
control_image -> control_encoder -> residual features
prompt -> text_encoder -> text condition
latent, t, text condition, residual features -> denoiser
```
```

## What to explain

- control_image is encoded separately.
- control_features align with denoiser blocks.
- The base denoiser still owns the main noise prediction.

## Common trap

- ControlNet is not a negative prompt.
- Control strength is not a universal quality knob.
