Unclear What practical difference the new error object shape makes, if any, is not stated.
What
When Claude Code's sandbox (a restricted execution environment) refuses to run a command on Windows because of policy, it now throws a cre error built from the command string, instead of the previous Vte error object.
Why
This is an internal implementation detail of how the refusal is represented in code. It doesn't change what happens visibly when a Windows sandbox policy blocks a command, but code that inspected the old error shape would need to account for the new one.
