Read compatibility before the version number
A recent Quark file may target Minecraft 1.21.1 and NeoForge, while an older line targets Forge on an earlier Minecraft version. Installing the newest file into an older pack is still a mismatch.
Treat compatibility metadata as a gate: if the game version or loader differs from your instance, stop and choose another build.
Match Zeta on modern versions
Quark versions from 1.20.1 onward use Zeta. The dependency also needs a compatible Minecraft and loader line. Updating Quark without checking Zeta can create a startup failure even if Quark itself is the correct game version.
Keep both files together in your change log so future updates are easy to audit.
Use a test profile for updates
Duplicate your instance before replacing a stable mod file. Test the copy, open a temporary world and review logs before updating the profile that contains important saves.
This is especially useful when a point release changes recipes, tags or module defaults.
Do not use source archives as normal mod files
A repository source ZIP is useful for reviewing source code, but it is not normally the same artifact as a compiled mod JAR intended for the loader.
If your goal is gameplay, use a loader-ready release file that states compatibility with your game version.
