🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Keep the latest blocking deadline for a shared SHA.
If two RFC pull requests share a SHA and both windows remain open, worst keeps the first failure. The commit status can then say that merging is blocked only until the first RFC’s deadline, even though the second RFC has a later deadline. Select the failure with the latest notBefore value, while retaining failures that have no labeled event, and test both pull-request orders.

Serialize shared status and index updates without dropping announcements.
This group lets a labeled run execute alongside an older run. If the older run reads the pull-request list before an RFC label is applied, it can publish its earlier success verdict after the labeled run publishes failure. run also rewrites the index from each run’s snapshot. Keep labeled announcements independent, but serialize or otherwise order status and index writes so an older snapshot cannot replace a newer one. GitHub concurrency groups do not serialize runs with different group names. (docs.github.com)

Same script as pcsx-redux/nugget: a head commit shared by two pull requests gets the failing verdict, labeled runs get their own concurrency group so the announcement cannot be dropped, and titles written to an index issue have @ escaped.
