The parallel execution model makes sense for independent tickets but I'm wondering what happens when agent A is halfway through a PR touching shared/utils.py and agent B gets assigned a ticket that needs the same file. Does the orchestrator do any upfront dependency analysis to detect that, or do you just let them both run and deal with the conflict at merge time?
It's generally not worth it worrying about it too much other than at a very high level vs. letting them fight it out, as long as your test suite is good enough and your orchestrator is even moderately prepared to handle retries.
