Use the voice-of-customer Skill.

Combine the supplied support and feedback records into a voice-of-customer report. Deduplicate customers and repeated events, tag hierarchical themes and sentiment, retain evidence IDs, and compare frequency by channel and period. Recommend distinct actions for product quality, customer support and product-page content.

The attached business materials are:
- inputs/brief.json
- inputs/merchant.json
- inputs/methodology.md

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.
