I guess functioneer and sysop rights should be enough to make these edits, so the edit should be safed.

Sounds like your attempted edit triggered the wikilambda-edit-predefined right, which it shouldn't have, yes. (Sorry for the low-context error message; fixing that is T351583.)

@Ameisenigel: However, I've re-created (what I imagine is close to) your edit in our test suite, and it seems to pass: https://gerrit.wikimedia.org/r/c/mediawiki/extensions/WikiLambda/+/1017875 – do you have any more information about the change you tried to make?

For Z64 I tried to add the following German labels:

• Z64K1: Identität
• Z64K2: Typ
• Z64K3: Umwandler
• Z64K4: nativer Typ
