Under the hood
The artifact database tool's internal code was renamed with no behavior change found
What
The validation, description, and summary code for the artifact database tool (db_op) was reorganized internally with new variable names, but the actual error codes and messages, such as requiring a doc_id and the restriction that read_db only saves to local directories, are unchanged. Similarly, the permission logic for the artifact database's write tool (handling version pins, deny/ask decisions, and batching) was extensively renamed without any new condition or message found.
Why
This is internal cleanup only; the previously known restrictions and permission behavior for the artifact database tools remain the same.
