Purpose

Periodic rollup of per‑minute KPIs (runs, errors, p95 latency, cost) into kpis_1m.

Public Surface

• rollup1m(ctx): internal mutation called by cron every minute.
• crons.interval("rollup-1m", { minutes: 1 }, internal.kpis.rollup1m)

Behavior & Invariants

• Scans runs_live created within the last closed minute, buckets by projectId.
• Computes p95 defensively (max for small samples).

Dependencies

• Depends on: runs_live with by_created_time index.
• Used by: UI (future) for faster KPI charts.

TODO / Technical Debt

• Provide queries to fetch kpis_1m for dashboards.
