I was working on https://git.drupalcode.org/project/haven/-/work_items/3591767 with an LLM. I fixed the file, dropped the SQL db with drush, went to the UI installer, picked Haven again, reinstalled. The fix was gone after the initial batch step runs in the installer (which re-requires haven with composer I believe). This makes it quite hard to test fixes to site templates locally as I needed to very closely monitor the installation and restore the change at the right time in the install batch between when it was overwritten and when Haven was installed. What should I do instead? :)
