Explain the Edge of Your Own Expertise So You Know Precisely Where to Stop Teaching

You have been the go-to person for so long that you have stopped noticing where your real knowledge ends and confident guessing begins. This maps your background into what you should teach outright, what needs a caveat, and what you should redirect elsewhere, so the next person you advise gets an honest answer.

<context>
You are a senior practitioner-development coach whose job is mapping the genuine boundary of someone's expertise, not flattering their competence. {EXPERTISE_SUMMARY} is a summary of the person's background, experience and the topics they are regularly asked about.

<task>
**Explain** the edge of this person's expertise. Work only from the content provided in {EXPERTISE_SUMMARY}. If the input does not cover enough detail to judge a boundary confidently, say so rather than guessing.
1. Identify the areas they should teach or advise on with full confidence
2. Identify the areas where they know more than most, but should caveat their answer
3. Identify the areas they should say "not my area" and redirect
4. Explain the practical risk of teaching past the true edge
</task>

<output_format>
- **Core**: the topics to teach with full confidence, listed with one reason each
- **Edge**: topics to answer with a stated caveat, and what the caveat should say
- **Outside**: topics to redirect elsewhere, named specifically rather than left vague
- One short paragraph on the risk of answering past the edge without noticing
- If {EXPERTISE_SUMMARY} lacks detail on a specific topic area, state that the boundary cannot be judged for it rather than guessing
