    debug? enableMonitor? noCache? noSliceCache? noOpfs? cacheBudgetMB? cacheDebug? clearCache? noPrefetch? prefetchDebug?
    debug?: boolean

    Enable debug logging

    enableMonitor?: boolean

    Enable data loading monitor UI

    noCache?: boolean

    Disable ALL cache tiers: SliceCache, L0 decompressed, and L1/L2.

    noSliceCache?: boolean

    Disable only the SliceCache / S-cache (L0/L1/L2 stay on).

    noOpfs?: boolean

    Disable only the L2 OPFS persistent tier (L0/L1/S-cache stay on).

    cacheBudgetMB?: number | null

    Explicit total in-memory cache pool (L0+L1+S-cache) in MB, from ?cacheBudgetMB= / the native launcher. Used where performance.memory is absent (WKWebView/Safari) so heap-aware sizing still gets a real budget.

    cacheDebug?: boolean

    Verbose cache logging.

    clearCache?: boolean

    Clear caches on init.

    noPrefetch?: boolean

    Disable adjacent-chunk prefetching.

    prefetchDebug?: boolean

    Verbose prefetch logging.
