Stats endpoints read hourly rollup tables filled once per closed hour by one advisory-locked task, instead of materialized views that re-scanned every observation on each refresh. IATA-set tables give exact distinct counts for any IATA set or region. Cleanup holds raw rows for unrolled hours (up to 24h). Adds /stats/series; ingest keeps packet observation counts, observer last IATA, channel message counts and trace tag summaries. 001_baseline.sql is rewritten, so pre-release 2.0 databases must be recreated. See docs/historical-stats.md.
