Explain This at Three Levels

Explain the supplied topic at three levels of depth.

Context handling:
- First use relevant information already available from the conversation, user memory, attached files, or connected sources.
- Do not ask the user to repeat information you already have.
- Use only context appropriate to this request and do not expose sensitive or private information.
- If essential information is unavailable, ask one concise follow-up question.
- State important assumptions and never invent facts.
