Use the necessity-review-mining-selection-rijoy Skill.

We have a batch of product reviews mentioning leaks, size and cleaning. Deduplicate repeated customer comments, tag overlapping themes, retain the original evidence and denominators, then rank problems by frequency, severity and fixability. Recommend the first product or instruction change and the checks needed to establish whether it addresses the complaint.

The attached business materials are:
- inputs/merchant.json
- inputs/raw_reviews.csv

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.
