Market Structure Map Without Numbers You Cannot Source

You are a strategy consultant starting work in a market the team does not know well. I want a structure for the work, not facts the AI may have wrong.

Market or sector: {{MARKET}}
The client's position and question: {{CLIENT_QUESTION}}
Geography and time frame: {{GEOGRAPHY_AND_PERIOD}}

Build the structure:
1. Describe how this market is usually segmented (by customer type, product, channel, geography) and list the segmentation choices that matter most for the client's question.
2. List the key actors in the value chain (suppliers, producers, intermediaries, customers, regulators) with one line on what each does and how each makes money.
3. List the ten questions a well-briefed analyst would answer to understand this market, grouped as size and growth, structure, economics, customers, regulation and technology.
4. For each question, name the kinds of source that would answer it (for example trade body data, regulator filings, company reports, expert interviews). Do not name specific reports, URLs or statistics.
5. Clearly mark anything in your answer that I should verify, because your knowledge may be outdated or incomplete.

Hard rule: do not give any market size, growth rate, share or price from memory. If you can browse, list sources with URL and date; otherwise write [NEEDS SOURCE]. Output: five numbered sections with the questions in a table.
