## Identity
- platform: wechat
- handle: 跨境选品人Elvin
- platform_url: https://weixin.sogou.com/weixin?type=1&query=%E8%B7%A8%E5%A2%83%E9%80%89%E5%93%81%E4%BA%BAElvin

## Reach
- posts_observed: 13
- verified: false
- size_tier: nano

## Engagement
- status: not_measurable_on_platform
- status_note: This platform publishes no follower count, so an engagement RATE has no denominator here. No amount of further collection can produce one — it is a property of the platform, not a gap in our data.
- unit_note: engagement_rate and peak_post_engagement_rate are ratios (0-1); avg_interactions_per_post and best_post_interactions are absolute counts. Read status before reading any number: a null rate has several different causes and status says which one applies here.

## Content
- category: ecommerce
- subcategory: ecom_tools
- category_confidence: 0.92
- category_source: derived_from_recent_content
- topics: Amazon product research, Niche market identification, Keyword-based product selection, Seasonal demand trends in pet and home goods, BSR ranking limitations, Market gap analysis for small categories

## Audience (inferred)

- posts_analysed: 5

- commercial.audience_buyer_fit: source_type=ai_inferred, confidence=0.6, freshness_days=12, method=llm_scorer — Relative signal within Koinon indexing, not a market-wide score.
- commercial.promotion_intent: source_type=ai_inferred, confidence=0.6, freshness_days=12, method=llm_scorer
- quality.anomaly_flags: source_type=heuristic, confidence=0.5, freshness_days=9, method=profile_snapshot_and_engagement_ratio_heuristic — Means "worth a manual check", NOT confirmed fraud. Flags can be wrong and are not a verdict about the person.
- quality.authenticity_score: source_type=heuristic, confidence=0.25, freshness_days=12, method=Fixed value 60. This platform exposes no public follower count, so no authenticity heuristic is run at all. The number is a placeholder, not a measurement. — The input set differs by platform; do not compare this score across platforms.
- quality.koinon_bd_grade: source_type=ai_inferred, confidence=0.5, freshness_days=9, method=llm_partner_fit_classifier + fit_score >= 0.5 => A; >= 0.35 => B; else C. authenticity is not an input. — Koinon partner-outreach fit, not creator quality.
