Caveats注意事项 —
13F = quarterly, ~45-day lag, reported long positions from managers with at least $100M in Section 13(f) securities. No shorts, no cash, no non-US positions. This desk is context — ownership is never a directional signal here.13F = 季度披露，约45天滞后，仅含美股多头且持仓≥1亿美元。不含空头、现金或非美股仓位。本台仅为背景参考——持仓数据在此永远不是方向性信号。
Grades and reliability are descriptive ranks within a curated survivor cohort — they measure what filings did after their filing dates, not a manager-selection edge. Conviction and core-lean reads are descriptive composites earning a forward record via the pre-registered ledger (L5); sector/theme classification applies the current map to history.评级与可靠性为精选幸存者队列中的描述性排名——衡量披露日之后持仓的表现，而非经理选择能力。信念分与核心倾向为描述性综合指标，通过预注册账本（L5）积累前瞻记录；行业/主题分类将当前映射应用于历史。
