Category: K-pop merchandise
Target market: US/EU importer review
Price band: not specified
Source status: mixed_or_fixture (products=fixture, trends=live)

## Buyer Question
Which product trend can be monitored legally without scraping resale marketplaces or fan-account data?

## Commercial Path
Signal Sprint: $500 USD
Send buyer brief + sample CSV + seller signal pack, then route serious buyers to the deal desk and operator-approved invoice path.
Growth Feed at $1,500/month after one category proves useful.

## Market Entry
Seller angle: Fan-merch sellers need legal product/trend signals and authenticity warnings, not private resale scraping.
First test: Use legal product/trend signals only, then ask the buyer for supplier proof before any paid delivery.
Compliance prompt: Check licensing, trademark, official supplier status, and marketplace policy before listing merch.
This is source mapping and sourcing prioritization, not legal, tax, customs, medical, or investment advice.
Source map: MFDS K-beauty ingredient preview is available as a separate proof asset; this category still needs its own official source-map before Compliance Scout claims.

## Guardrails
- No Olive Young/private endpoint bypass.
- No marketplace login scraping or cookie/token reuse.
- No compliance clearance claims; only source mapping and next-check prompts.
- No guaranteed revenue, margin, ranking, or conversion claims.
- No payment collected or external message sent by this endpoint.

## Boundary
Seller signal pack only. It does not claim compliance clearance, supplier authorization, private marketplace coverage, guaranteed revenue, or payment collection.
Warning: Live fetch failed (combined product search empty (all sources returned nothing)); deterministic fixture served as fallback.
