What it does

Once an emerald block is placed next to an Iron Door, the door stays locked permanently and ignores redstone signals reaching it. A master key opens such a locked door, and the key is made with a recipe built around the Data Diver. The mod runs on Fabric for 1.21.1 only, and it is needed on both the client and the server, with the MIT License covering the code, which is not open source.
