+## Decision
+
+Routing decision: blocked_pending_dependency
+
+Panel Queue により routing 対象として確認したが、`00001KVHR3WS6` は `00001KVHR3WRY` に `depends_on` している。MCP tools/list registration は initialized stdio lifecycle を前提にするため、`00001KVHR3WRY` が closed になるまで実装開始せず queued のまま保持する。
+
+Next:
+- `00001KVHR3WRY` が closed になった後、改めて reroute する。
