I checked this laravel/cashier-stripe#1810 and some PRs related to it, and, like you, it was also working for me. But I was curious, so I did some deep digging into it, and I found that publishedAt property gets initialised with now(), which uses Date::now() behind the scenes and when someone uses Date::use(CarbonImmutable::class) at that moment it does not mutate. It creates a new object for each iteration. It creates all migrations with the same date and time that makes it resort in alphabetical order and that's why adding column migration runs before creating table migration.
