- entity_type: creator
- person_id: Cross-platform identity not resolved for this creator.

## Reach
- followers: 586
- following: 413
- posts_total: 1294
- posts_observed: 4
- posts_per_day: 0.209
- account_age_days: 6195

- size_tier: nano

## Engagement
- status: peak_post_only
- peak_post_engagement_rate: 0.00512
- best_post_interactions: 3
- measurement_source: x_post_interactions
- measurement_formula: interactions on one post — likes, or likes + reposts + replies depending on the discovery path (the two are not distinguishable in the stored data)
- comparable_pool: peak_interactions
- status_note: We have only the single best observed post, so no mean exists. peak_post_engagement_rate is an UPPER BOUND, systematically higher than an average — never compare it against an average rate.
- 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.

## Evidence
- [x_0xee20#bfec330c] 7月31日海外市场复盘：指数上涨，广度未扩，AI进入现金回报验收。 • 云平台看收入、利润与FCF • 芯片看出货、毛利、库存 • 电力链看送电、融资、回款 • 软件与运输看单位经济 下周看长端、AMD/SNDK和云利润。产业复盘，不作为操作依据。 #AI #半导体 #海外市场 https://t.co/amYJdZ8FZ1 (https://twitter.com/0xee20/status/2070539093860311334)
- [x_0xee20#28572d1a] 前面讲的日线回调可能结束了，下面看这轮日线的上涨能不能突破六万七这个粗略的压力区间。 跌破62500的话，视为上述判断错误，会走一个再深度的回调。
- [x_0xee20#d8c29777] SK海力士ADR为什么溢价？2.5%和25%到底是什么 先说现状。 SK海力士今年7月以SKHY为代码在纳斯达克发行ADR。每1份SKHY代表0.1股韩国普通股，也就是1股韩股对应10份ADR。虽然两边代表的是同一家公司的同一种经济权益，但SKHY上市后一直明显贵于韩国普通股。 截至7月22日，SKHY收盘价为165.27美元。按7月23日韩股价格及美元兑韩元汇率折算，SKHY相对韩股的溢价约为27%。同一份股权在美国贵了接近三成，市场自然会想到跨市场套利。 正常的套利方法很简单：买入较便宜的韩国普通股，把它转换成ADR，再到美国卖出价格更高的SKHY。

- quality.authenticity_score: source_type=heuristic, confidence=0.5, freshness_days=80, method=Profile-shape heuristic from a single snapshot (follower count, following ratio, account age, posting volume, verification), reduced for engagement red flags where post engagement was collected. Where only a follower count is available the score saturates at 58. — 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=110, method=llm_partner_fit_classifier + fit_score >= 0.6 AND authenticity >= 60 => A; fit_score >= 0.4 AND authenticity >= 45 => B; else C. authenticity < 30 or a promotional-pattern flag => quarantine. — Koinon partner-outreach fit, not creator quality.
