### What happened

The “FLUX.2 Klein Qwen3 8B Encoder” was installed from Model Manager / Starter Models, not manually imported.

Download is complete: 16.4 GB.

Installed files:
text_encoder/config.json
text_encoder/generation_config.json
text_encoder/model.safetensors.index.json

tokenizer/merges.txt
tokenizer/chat_template.jinja

text_encoder/config.json:
"architectures": ["Qwen3ForCausalLM"]
"model_type": "qwen3"

Behavior:
- Model Manager marks the official encoder as “Unable to identify model.”
- Reidentify does not resolve it.
- Editing it to mark it as Qwen3 / the appropriate encoder returns “Model update failed.”
- Other model installs and model-management actions work.
- Because the model stays Unknown, it cannot be selected as the Klein 9B encoder.

### What you expected to happen

The official Starter Model should register as “FLUX.2 Klein Qwen3 8B Encoder” and be selectable for FLUX.2 Klein 9B.

### How to reproduce the problem

Open Model Manager
install “FLUX.2 Klein Qwen3 8B Encoder”
