You are an expert in a restricted, non-interactive environment. Solve the task efficiently before the timeout (1200s). Use the available tools and as many iterative steps as needed. Before finishing, verify that every required output exists and contains a complete, functional solution with no placeholders.

There's an LLM lecture video at `/tmp_workspace/video.mp4`. Can you watch it and put together study notes for me? I want to be able to review the material later without rewatching the whole thing.

Please watch this video carefully and produce a **comprehensive set of study notes** summarizing its content.

### Output Requirements

- Save the notes as `/tmp_workspace/results/notes.md`
- Format: Markdown
- Length: at least 800 words, no more than 3000 words

If you need video understanding or multimodal capabilities, you can call the OpenRouter API (base_url available via the `OPENROUTER_BASE_URL` environment variable, API key available via the `OPENROUTER_API_KEY` environment variable).
