Buildbtw dropped all non-x86_64 targets, and a fresh Junior Package Maintainer joined the team.

Buildbtw now refuses to configure pacman repos for architectures it can't actually build, trimming the support matrix down to x86_64 only [1]. The change lands via a merge that removes architectures we don't build for yet [2], paired with a fix that creates the empty pacman repo dbs only after build graphs are calculated [3]. The team also cleaned up naming and plumbing, renaming KnownArchitecture to BuildArchitecture [4] and passing the build architecture into pkgctl build [5]. Meanwhile, the infrastructure desk onboarded Josie as a Junior Package Maintainer [6], with the merge noted as the onboarding step [7]. Away from the builder, Caleb Maclennan bumped Luau to 1:0.735-1 [8] and Tobias Powalowski moved kmscon to 10.0.2-1 [9]. The only lint fix worth noting is the Ansible cleanup in anubis, which addresses a yaml[empty-lines] warning [10].
