memory_chunk_context: memory driver does not support the chu

Error message

memory_chunk_context: memory driver does not support the chunk family

What it means

The bound driver's as_chunks() is None — chunk context requires the chunk family to fetch the target and its neighbours. Chunks are deliberately read through the bound driver, never by opening the store in-process.

Solutions

1. Use a chunk-capable driver
2. Check why the active driver lacks MemoryChunks
3. Fall back to a plain memory search for context
