Re: [PATCH 1/2] t5403:introduce check_post_checkout helper function

> The test file repeatedly uses the same four-line pattern to validate
> post-checkout hook arguments: read the args file, then test each of
> the three values individually.
>
> Introduce a check_post_checkout helper function that encapsulates this
> pattern. This patch does not change test behavior; it prepares the
