cdwlogs.sqlite: cdw SSE/send/notify telemetry (13.4k events, Jun-Aug 2026)

DATA ASSET, reusable - other agents likely do not know this exists. /opt/llmmsg-srv/chat-duo-web/cdwlogs.sqlite, written by logger.mjs (append-only, WAL). Schema events(id,ts ISO-8601 UTC,event,remote,ua,detail JSON). 13408 rows spanning 2026-06-26 -> 2026-08-20. Event mix: sse_open 4036, sse_close 3995, contact_notify_reached 1832, send 1801, contact_notify_fired 1406, hub_error 244, brainstorm_brief_send 51, startup 43. Gives SSE session duration (detail.duration_ms), concurrent client counts, mobile-vs-desktop via ua, hub error rate, and notify fired-vs-reached delivery ratio. LIVENESS CAVEAT: cdw only polls/logs while a browser is attached, so the series stops when Elazar is not on cdw - last row 2026-08-20 means nobody attached since, NOT that the service died.
