Simulate the questions an expert would ask

Simulate the questions a world-class expert in this domain would ask after reading every source in this notebook.

Produce 15 questions, grouped as:
1. Five clarifying questions — things an expert would need answered before forming any opinion. These should expose ambiguity in the sources.
2. Five probing questions — questions that test whether the strongest claims actually hold up. These should target weak evidence, suspicious certainty, or missing context.
3. Five generative questions — questions that open the topic to new territory: what would change everything? what would the sources predict about adjacent problems they don't address?

For each question:
- Phrase it the way an expert would actually ask it — concrete, not abstract.
- Note which source(s) would be most relevant to the answer, or "Not addressed by current sources" if none.
- Add a one-sentence note on what a strong answer would unlock.

Avoid soft, polite, or beginner-friendly questions. These should be questions an author would lose sleep over.
