+2. 在 workflow overview URL workflow result 中保留当前 filter selection
+   的 structured summary，方便外部 shell 读取；
+3. 可选：支持 query/hash 参数预选 family/sourceKind；
+4. 继续保持 promotionAllowed=false、baseline=82/82/77/0；
+5. 验证仍以 Node UI smoke、INI browser smoke、SDK surface、docs smoke 为主。
+```
+
+十四、本轮接续推进：evidence expansion filter summary/action-plan
+
+执行时间：2026-06-20 CST
+
+已完成第十三节建议中的可复用输出层，不改变 inventory baseline，也不扩大
+TRT family 候选集合。

+新增 API / SDK / 页面 surface：

+
+```text
+1. 支持 workflow overview 的 query/hash 参数预选：
+   - evidenceExpansionFamily=evidence-expansion-family-five-axis-trt
+   - evidenceExpansionSourceKind=gcode
+2. 预选只驱动 filter view-model 初始状态，不写入 inventory/report artifact；
+3. browser smoke 覆盖预选后 body dataset / DOM selectedFamilyId /
+   selectedSourceKind / filtered count；
+4. SDK summary/action-plan 保持 promotionAllowed=false、baselineChanging=false；
+5. baseline 继续保持 82/82/77/0。
