可信度：HIGH。The bounded corpus is triangulated across three source families with material critical evidence and counterevidence.

统计分母：All valid, comment-level observations in this bounded Phase 4.4 corpus; counts are not population prevalence.

• Final supplier and exact target SKU
• Formal quote, MOQ, packaging, production lead time, and quality terms
• Landed cost, duty, fulfillment cost, return reserve, CM1, break-even CPA, and ROAS
• Physical opacity, seam durability, wash recovery, waistband roll, chafing, camel-toe, and fit performance
• Target-product fiber/care/country-of-origin labels
• Product-specific evidence for any health, circulation, cellulite, compression-performance, clinical, or patent claim
• Reliable current Google Trends time series and first-party marketplace sales data
• P0｜Which supplier and exact SKU will be sampled?：The public Alibaba listing is only a candidate and cannot be mapped to Ionix or a final target product.
• P0｜What are the target SKU landed cost, duty, packaging, fulfillment, return reserve, and paid-media assumptions?：Public listing prices and weights are not a formal landed-cost quote.
• P0｜Are any circulation, cellulite, swelling, lymphatic, clinical, patented, or medical-compression claims supportable for the target SKU?：Competitor claims cannot transfer to the target product and no product-specific study or patent review was provided.
• P0｜Does the sample pass squat opacity, seam durability, wash recovery, waistband roll, chafing, camel-toe, and size-fit tests?：These properties require physical sample validation across sizes and body shapes.
• P1｜What is the current US Google Trends time series for butt-lifting and scrunch leggings?：The dynamic Trends page could not be captured in this run.
• P1｜Are Ionix review counts, customer counts, return rate, clinical testing, and patent statements independently verifiable?：They were observed only as merchant claims.
