Every incoming echo triggers a sweep of the whole rendered message list, and refreshMessagesMeta() awaited one /api/messages/<id>/meta per message inside the loop. Messages that never gain a route (nothing heard them) never stop qualifying for the sweep, so the same ~180 messages were re-fetched every few seconds: 7,500 requests in nine minutes on a single tab, each opening its own SQLite connections. The single-threaded werkzeug server — the same one production runs — had no room left for anything else, so the UI hung on "Loading messages..." / "Connecting..." while the device was in fact connected. Add GET /api/messages/meta?ids=... resolving the whole sweep with a handful of queries, batching the row and echo lookups, and have the client collect ids first and fetch them in chunks. The per-message endpoint stays for forced single refreshes; both now share _build_message_meta() and the existing _build_channel_secrets / _get_row_pkt_payload helpers, so the payload is unchanged (verified byte-identical against the old response). Measured on the local container, 500 messages rendered / 181 needing meta: one 273 ms request in place of 181 sequential ones at ~82 ms each. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
