memory_hybrid_search: {e}

Error message

memory_hybrid_search: {e}

What it means

Wrapper around active_memory_guard() in hybrid search: the bound driver could not be acquired. The comment notes this path deliberately avoids constructing a second engine over the workspace — reads go through the module-owned driver only.

Solutions

1. Retry after driver binding
2. Check the chained acquisition error
3. Verify the memory module is loaded and healthy
