Clarification on /assign and PR closing logic

[ame2en]

If I use the /assign command in the comments of an issue to claim it, what happens if another contributor submits a PR for that same issue?

Specifically:

Does the system allow a PR from a non-assignee to automatically close an issue I am assigned to (e.g., by using "Closes #123" in their PR description)?

Is there a "protection" period for assignees, or is it strictly first-come, first-served regardless of the assignment status?

From my point of view, assignment should probably be treated as coordination rather than hard lock ownership, otherwise issues can stall too easily. The more important part is making the current ownership state and expectation visible so contributors know whether they are helping, competing, or duplicating work. A short maintainer note on how assignment interacts with linked PRs would probably remove most of this ambiguity.
