I don't know devbox. No idea what it does or if it's helpfull here. Maybe someone else can look at it?

I did not know it before and I can see why people recommend it.

What confused me was the devbox.lock file but this is intentional (point 5.)

Imho contribution.md or readme.md could use a first script instruction to validate the contribution, e.g. use devbox run test to calidate your contribution etc.

the github-ci includes the test run, so there is already a validation...

Please re-run all tests, code changed quite a lot
