+## 2026-05-25 T187 — Source Refs Gap Breakdown 前端可視化
+
+**背景**：
+
+- T186 已補未來出站鏡像的 button callback incident ref extraction。
+- 但 Run 監控仍只顯示 `source_refs / incident refs / 覆蓋率`，operator 無法判斷缺口是在一般資訊訊息、approval card、還是帶按鈕但未含 incident refs 的舊卡片。
+
+**本輪修正**：
+
+- `/api/v1/platform/runs/callback-replies` summary 新增：
+  - `outbound_reply_markup_total`
+  - `outbound_reply_markup_missing_incident_ref_total`
+- Run 監控 `TG Callback Evidence` 的 Outbound mirror 卡新增 gap breakdown：
+  - `reply_markup {replyMarkup}；按鈕缺 incident refs {missingIncidentRefs}`
+- 這讓 operator 能看出 source matching 缺口中「可由卡片/按鈕 extraction 改善」的部分，而不是只看到一個總覆蓋率。
+
+**local validation（完成）**：
