Sorry, I don't have time to review it today, tomorrow I'll try to investigate more.

[ProjektGopher]

I see two issues here, we're not normalizing the composer paths in our code, and then the directory returned by composer global home/bin doesn't match where it's actually being executed from. Once of the directories in that path must be a symlink

[ProjektGopher]

I'm glad I added that audit command. This is so much easier to diagnose 💪

[ProjektGopher]

I wonder if the easier way to determine isRunningGlobally() is to just search the base_path for 'composerHome' | '.composer' instead of using str_starts_with and passing getGlobalComposerHome.

[ProjektGopher]

It seems like composerHome is a non-standard directory name.

Some comments:

• This package is not "Wamp", it is "Wamp.NET" (it has the same philosophy but it is another implementation).
• It effectively uses a symlink on Windows to quickly switch between different versions of PHP (each version of PHP has its own ComposerHome).

Exactly, Composer for Windows installs the data in C:\Users\(your user)\AppData\Roaming\Composer, and does not set the COMPOSER_HOME environment variable, if it is set that environment variable can be rewritten, but use default location
