Studio multi-line Command Bar executes only part of a script

Issue
A pasted maintenance script stops early or behaves differently from a normal Script.

Cause
The selection, incomplete block, environment assumptions, or asynchronous work is not suited to one Command Bar execution.

Fix
Use the current multi-line Command Bar, verify complete matching blocks, and test on a copied place. For repeatable or destructive migrations, place reviewed code in a temporary plugin or server script with logging rather than relying on an unversioned paste.

Verify
Print a planned change count first, execute on a duplicate, and compare the resulting DataModel before touching production.
