+incident_join_quality:
+total=150 with_aol=100 with_evidence=102 with_legacy_mcp=102 with_timeline=102 with_approval=102 with_auto_repair=10
+
+Sentry / SignOz durable event tables:
+none found by information_schema table_name ILIKE '%sentry%' OR '%signoz%'
+```
+
+**判讀**：
+
+- MCP / SignOz 能力已有實際使用，且 legacy MCP bridge 已寫入 AwoooP Gateway audit。
+- 仍不能宣稱完整 AI 自動修復：24h incident 150 筆中只有 10 筆有 `auto_repair_executions`。
+- Telegram outbound mirror 有資料，但 `sent_at=0` 是真缺口；source envelope 也缺少 structured source refs，truth-chain 只能靠 `content_preview ILIKE` 猜關聯。
+
+**變更**：
+
+- `record_outbound_message()` 在 `send_status='sent'` 時寫入 `sent_at=NOW()`。
+- Telegram outbound `source_envelope` 新增 `source_refs.incident_ids` 與 `source_refs.code_refs`，保留 redaction-friendly 關聯錨點。
+- truth-chain outbound 查詢支援 structured `source_refs`，不只靠 preview 文字搜尋。
