As part of SERVER-112053, we re-structured the CAR folder hierarchy to align with CAR modules (shard_role, router_role, topology, and global_catalog) and reviewed the files contained on each module. During this work, some files were identified as not clearly belonging to a specific CAR folder and were temporarily moved to an upper layer.

The goal of this ticket is simply to either:

• Move the files to a more specific folder, or
• Keep them where they are and close the ticket as Works as Designed.

The impacted files are:

• src/mongo/db/index_repair.cpp/.h
• src/mongo/db/index_key_validate.cpp/.h
• src/mongo/db/index_key_validate_test.cpp
• src/mongo/db/index_spec_validate_test.cpp
• src/mongo/db/throttle_cursor.cpp/.h
• src/mongo/db/throttle_cursor_test.cpp
