# Batch Check

Space-scoped existence check for file/folder ids.

Used by Central Hub's lazy self-heal of agents' ``enabled_file_scope``
(COR-1768): ids missing from the response were deleted (or never
belonged to this space) and can be pruned from the agent's selection.
The literal ``"root"`` is always reported as existing.
