We need to create tables to generate the voter list for the 2026 UCoC annual review and 2026 U4C elections. The eligibility criteria is the same for each.
Once the patch is merged we will run the script closer to the vote itself (just in case additional wikis are created). See the similar task, for example, T398900.
Same caveat as that task: I understand this is discouraged behaviour now (see T355594: For global elections, stop creating eligible voters table for each election on every wiki and keeping them forever) but there is no alternative at the moment.
