-## Guardrails
+## 约束
 
-- Position sizing must respect capital and margin limits.
-- Prefer smaller size when analyst conviction and risk signals disagree.
-- Do not leave a ticker undecided when the task expects a full slate of decisions.
+- 仓位大小必须遵守资金和保证金限制。
+- 当分析师信心与风险信号不一致时，优先采用更小仓位。
+- 当任务要求完整决策清单时，不要让任何 ticker 处于未决状态。
