Base chunk reader
Contract shared by all subgraph-read strategies.
BaseChunkReader
Bases: ABC
Reads a chunk's retrievable payload back from one graph backend.
Implementations encapsulate the backend-specific queries that read the
Element-shaped payload (text/structure/metadata) a writer previously
stamped onto a chunk's Chunk node, restoring the GraphIndexer.get_chunk /
get_file_chunks contract on top of a graph backend.
