+## 完了
+
+Closed as completed by the subsequent Panel startup E2E and latency-improvement sequence.
+
+The initial work separated first visible frame readiness from background reload, but later review showed that user-visible startup latency must be measured at dashboard content-ready, not first frame or single-row readiness. The later Tickets added dashboard snapshot readiness, shell-enter launch-path coverage, live workspace measurements, and the actual startup fix for duplicate Pod probes/session-log scans.
+
+Relevant follow-ups:
+- 00001KV62PF32: corrected readiness away from first frame / weak row count;
+- 00001KVDETSN6: dashboard content-ready snapshot metric;
+- 00001KVDQH839: shell-enter launch-path measurement;
+- 00001KVF0ZJM5: fixed live startup by reusing initial Pod list presence and avoiding session-log reads before first rows.
