    configSha256: string

    SHA-256 of the validated runtime configuration bytes.

    effectiveConfigSha256: string

    SHA-256 of the JSON actually passed to native initialization, including transport URLs, tile-cache settings and search-memory overrides.

    graphStartupBytes: number

    Validated startup body bytes, including manifest/config and loader metadata.

    graphStartupMs: number

    JSON metadata download/validation plus native graph-reader initialization time.

    graphStartupRequests: number

    Fetch attempts during startup, including manifest/config and loader metadata attempts.

    loader: LoaderMetrics

    Loader counters sampled at startup completion.

    memoryBudgetBytes: number

    Effective retained decoded-tile cache budget in bytes.

    moduleStartupMs: number

    WASM loading/compilation/instantiation time inside the worker.

    native: NativeStats

    Native identity and memory counters sampled at startup completion.

    release: string

    Immutable dataset release ID.

    searchMemory: EffectiveSearchMemory

    Effective search-label reservations and cleanup policy for this actor.

    supportedCostings: readonly Costing[]

    Profiles supported by both this SDK and the dataset manifest. Old auto-only datasets remain driving-only.

    wasmMemory: EffectiveWasmMemory

    Resolved per-instance WASM linear-memory settings.

    workerReadyMs: number

    Main-thread elapsed time until the worker and graph are ready, including worker loading.
