If multiple interpreters satisfy

interpreter_constraints

, which interpreter is chosen? How can I control which is chosen if e.g. I allow Py3.10-3.12, and want to force use Py3.11 for reasons?

You can set it on individual targets, if that's helpful. If you want to do this across the whole codebase you could override it as a command-line argument. Regarding "which is chosen" if you leave it open, I don't know unfortunately.

Maybe I can relax the question a bit: when pants selects an interpreter out of multiple valid options, is it guaranteed to keep selecting this one? I.e., is the selection 'ordered'.
