memory_chunk_context: get_chunk failed: {e}

Error message

memory_chunk_context: get_chunk failed: {e}

What it means

Capability guard in the memory_chunk_context tool's execute: guard.as_chunks() returned None, meaning the active memory driver does not implement the chunk family, so chunk context cannot be read. Driver-capability boundary, not bad input — the get_chunk call is never attempted.

Solutions

1. Retry transient driver failures
2. Verify the chunk id came from a fresh search (it may have been dropped)
3. Inspect the chained error for the underlying fault
