Two draft task-by-task plans for the two Scale/YAGNI deferrals whose revisit
triggers are now in view:
- #10 aggregated live alarm stream: transient per-site in-memory central live
cache seeded by the snapshot fan-out + additive SubscribeSite alarm-only gRPC
stream, pushed via the IDeploymentStatusNotifier pattern; honors the [PERM]
no-central-alarm-store rule. 8 tasks.
- #22 KPI hourly rollups: separate KpiRollupHourly table, recorder hourly fold
with failover-safe lookback re-fold, per-metric gauge-vs-rate aggregation,
range-threshold routing in the query service, longer rollup retention, one-shot
backfill, plus 30d/90d window buttons so rollups have a caller. 8 tasks.
