scala-smtlib is fetched via sbt's RootProject(uri(...)), which clones and compiles it into the sbt global staging directory. On self-hosted runners this directory is shared across runners and persists across runs, causing stale .tasty/.class files and race conditions between concurrent jobs. Setting SBT_GLOBAL_BASE to a workspace-local path isolates each job. Can be reverted if scala-smtlib is published to Maven. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
