ConstReadonlyaccrualMaxPendingAgeMs: numberAn accrual row pending longer than this means the drain lags its backlog.
ReadonlycheckpointMaxAgeMs: numberA sealed checkpoint older than this means the seal cadence stalled.
ReadonlyenumerationCap: 10000Gauge walks stop counting here; a capped count reports >= cap, never a made-up total.
ReadonlyhistorySizePostings: 10000000History size where partitioned DDL / the archival mover earn their provisioning cost.
ReadonlyreproofMaxAgeMs: numberA re-proof watermark older than this means rotation lags the coverage story.
ReadonlytableRows: 10000000Secondary-table rows where growth needs a retention answer: the retention sweep's horizons where one exists, a host policy where none does.
The documented crossover thresholds CapacityReport.advisories states facts against. Crossing one changes nothing by itself; it is the signal to activate the corresponding knob (partitioning DDL, archival mover, drain cadence, orphan sweep).
