    l0Provider sliceProvider? cacheStatsProvider loaders metricsCache rates telemetryState?
    l0Provider: L0Provider | null
    sliceProvider?: SliceProvider | null

    Optional so existing callers/tests need no change; the real monitor always passes it. Absent → no SliceCache row in the aggregated metrics.

    cacheStatsProvider: CacheStatsProvider | null
    loaders: Map<string, LoaderMonitor>

    Active loaders whose metric snapshots are refreshed into metricsCache.

    metricsCache: Map<string, LoaderMetrics>

    The monitor's metrics-snapshot map. Mutated in place: each loader's current getMetrics() is written under its path so subsequent reads see the latest values.

    rates: CacheRatesSnapshot

    Pre-computed per-second rates from calculateRates(). Read-only here; passing them in keeps the aggregator pure relative to the monitor's mutable rates field.

    telemetryState?: CacheTelemetryState

    Explicit cache telemetry state. When omitted, defaults to not-wired (the most honest fallback when no provider exists).
