custom scripts exempt from duplicate prefix enforcement?

[FliesLikeABrick]

We have "unique IP space" (prevent duplicates) enabled on all of our VRFs in NetBox IPAM. The UI properly enforces this as-expected.

However, our Custom Scripts appear to bypass this check. Is this expected? If this is expected, is there an atomic/script-friendly way to "create unless present", or otherwise have something that behaves like an atomic transaction? That is, if we need the script to intentionally check for existence before creation, we would want to avoid a "time of check/time of use" race condition where another action in the environment can create that prefix after the check is performed.

What's the save method used by your script? Does it use the full_clean() method first?

I am using .save() on individual prefixes as they are created. I had not previously been aware of full_clean, it seems like that is an underlying django thing - I will look into that now, thank you.

This was what I needed and did start enforcing the duplicate checks, thank you
