The 128 KB Akka frame-size deploy trap is fixed and merged. Record the resolution at the top of the writeup (notify-and-fetch on both the central->site deploy hop and the site active->standby replication hop; AskTimeout classification fix; startup reconciliation + topology perf fix), link the design + plan docs, and note the live-smoke validation. The diagnosis is retained as historical record.
