💭 Fixing test configurations I need to address the existing HOST test by ensuring it fits the newly added environment test. To do this, I'll explicitly extend it before adding. I can fold the existing case by integrating inherited variables and assertions in both modes. I'll also comment on line 194 to clarify, and I need to fix the multi hunk situation where there's no difference. Additionally, I should note that the CLI behaves differently, and that distinction is justified.
