Member Junction
    Preparing search index...

    Chunk-level provenance recovered from an external index document.

    External indexes are populated outside MemberJunction, so these fields are present only when the indexing pipeline chose to emit them. Every field is optional by construction.

    interface ExternalChunkProvenance {
        ChunkID?: string;
        ContentItemID?: string;
        EndMs?: number;
        Modality?: string;
        PageNumber?: number;
        StartMs?: number;
    }
    Index
