memory_tree: unknown mode `{other}`. Valid: search_entities,

Error message

memory_tree: unknown mode `{other}`. Valid: search_entities, query_source, drill_down, cover_window, fetch_leaves, ingest_document, walk, smart_walk

What it means

The memory_tree dispatcher matched the mode string against its exhaustive match and fell to the catch-all arm. The value is echoed with the full valid list; new modes must be added to both the match and this message.
