    Interface QuerySnapshot<T>

    Immutable snapshot of a cached query. The same object reference is returned from HonuaQueryCache.getSnapshot until the underlying state changes, which is what gives hooks their referential stability (NFR-001).

    interface QuerySnapshot<T> {
        data: T | undefined;
        dataUpdatedAt?: number;
        error: unknown;
        isFetching: boolean;
        isLoading: boolean;
        status: QueryStatus;
    }

    Properties

    data: T | undefined

    Last resolved value. Preserved across background refetches.

    dataUpdatedAt?: number

    Epoch milliseconds of the last successful fetch, undefined until one resolves. Drives stale-while-revalidate decisions.

    error: unknown

    Last rejection reason, cleared on the next successful fetch.

    isFetching: boolean

    True whenever a fetch is in flight, including background refetches.

    isLoading: boolean

    True only while the first fetch (no data yet) is in flight.

    status: QueryStatus
