ryan	da1dd92404	fix(observability): merge rollup+raw hourly trends and backfill history ... Prefer capacity/openresty rollups only when they cover the 24h window; otherwise merge per hour so raw fills pre-MV gaps and rollup wins on overlap. Add a one-time ANTI JOIN backfill migration for the last 30 days.	2026-07-10 11:27:51 +08:00
ryan	4b11279662	fix(observability): fall back to raw hourly when rollup is incomplete ... Materialized capacity/openresty hourly tables only hold data after the MV exists. Preferring any non-empty rollup hid full raw history and left 24h charts with only recent hours. Use rollup only when its earliest bucket covers the query window start.	2026-07-10 11:27:51 +08:00
ryan	160e63558f	fix(clickhouse): harden R/W path P0–P3 (cleanup, durability, rollups) ... Honest TTL cleanup semantics; enqueue-safe dedup with flush retry and writer metrics; model insert hooks; latest-per-node and hourly metric/openresty rollups; small-host pool/async defaults, traffic hourly TTL, and UV labeling.	2026-07-10 10:34:04 +08:00
