Frequently asked questions

Is the ZIP a real datapack?

Yes. It contains pack.mcmeta and the resource JSON in the singular Java 1.21.11 directory. ZIP integrity is checked independently.

How are generated files validated?

Fixtures pass the official offline Java 1.21.11 codecs. Unknown fields, invalid IDs, unsafe paths and oversized inputs are rejected; a live world is not simulated.
