# Conditioning Flow

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 text/image/video conditions as separate encoder paths that meet inside the denoiser.

## Annotated sketch

```text
## Conditioning flow

```text
prompt -> text_encoder -> text_context
reference_image -> vision_or_vae_encoder -> image_context
control_signal -> control_encoder -> block_residuals
all contexts -> denoiser(latent, timestep, contexts)
```
```

## What to explain

- text becomes embeddings.
- image/video reference may become latent or encoder features.
- control is injected at defined blocks.

## Common trap

- Do not reduce every condition to a prompt.
- Do not ignore where the condition enters the model.
