Use the market-research Skill.

Before funding expansion, estimate the addressable market from our supplied market and segment assumptions. Show top-down and bottom-up TAM, SAM and SOM, explain any mismatch, rank target segments and design a proportionate survey with sample and invitation counts. Deliver the questionnaire and a decision brief that makes the assumptions visible.

The attached business materials are:
- inputs/brief.md
- inputs/evidence.md
- inputs/market.json
- inputs/merchant.json
- inputs/segments.json
- inputs/survey.json

Deliver a complete result.md report that the operations team can read, plus any finished files needed for this task. Keep supporting calculations and evidence with the deliverables. Write the report in English; use the requested target language for customer-facing copy. The business datasets are fictional examples unless the brief explicitly names a live public website.
