Function TestWorktreeFilesystemMkdirAllRootIsNoop

worktree_test.go:3254–3272

TestWorktreeFilesystemMkdirAllRootIsNoop locks in the contract that MkdirAll on a root-equivalent path is a silent no-op against the wrapper. validPath itself still rejects "", ".", and "/" (see TestValidPath), but MkdirAll specifically tolerates them because "ensure the root exists" is always trivi

(t *testing.T)
