+  The daemon log showed 18 connected-server source-search timeout warnings and
+  18 sent connected-server source searches, down from 72 timeout warnings and
+  41 sent searches in
+  `EMULEBB_WORKSPACE_OUTPUT_ROOT\live-wire\rust-hideme-20260618T173921Z`. The
+  same run captured 30 batched outbound `OP_GLOBGETSOURCES` packets, each with
+  an 18-file payload, sent to 30 distinct servers.
+
+The live run did not complete a download before timeout, so it is not a full
+end-to-end pass. It is sufficient evidence for this server-source pacing fix
+because the connected-server retry churn was eliminated while VPN binding,
+HighID, Kad connectivity, and packet diagnostics were active.
