yeah. it's using what you see in the UI here.
so if you made a change to a task used in a pipeline (my pipelines are from tasks, not functions... can't speak to that but i think it just generates a hidden task under the hood), point the (draft) task to that commit (assuming it's pushed), or re-run the task. the pipeline picks up from the tasks the API is aware of (by id or by name, in which case it uses latest updated) under the specified project, not from local code.

that part was confusing for me to understand at first, but now I have the mental model for how they work.
