DMartin-WMF closed this task as a duplicate of T412952: Increase capabilities and usage of evaluated implementations to improve performance.Jan 7 2026, 1:12 AM

I don't think this should be marked as a duplicate of T412952, which is a time-bound piece of work that might or might not accomplish all of this Epic?

Good point, @Jdforrester-WMF ; thanks. I interpreted this ticket according to its brief list of subtasks, which were either done or may be done as part of T412952. In other words, I didn't interpret this ticket to be all-encompassing with respect to supporting reentrancy. Either way, you are right it's not accurate to call these 2 tickets duplicates. I will re-open to remove the duplicate connection and also because there is still an open subtask.

DMartin-WMF reopened this task as Open.Jan 11 2026, 9:03 PM

Regarding the remaining subtask T334485, we are considering whether to include that under T412952, but it seems unlikely at this point.
