Reports

Not built yet.

Two separate gaps, both real. First, no reporting capability exists anywhere in the product yet: there is no reports table in sql/ and no /reports route in cmd/ewuscloudd. Second, this section in particular has no source data to report on -- slo_definitions, perf_rollups and perf_alerts are all absent from sql/, and device_metrics has never been written to because no gateway sends telemetry yet (a real read endpoint over it now exists, but reading zero rows is still zero rows). Both have to be built before a performance report can contain anything true.
