SWE Atlas v1.1 - Test Writing

Scale

Test Writing component of SWE Atlas v1.1, on writing production-grade tests for repository behavior. Part of a suite of 284 tasks from 15 production repositories in 6 languages, run in Docker with standard shell tools and re-run for v1.1 with a GPT-6.1 Sol judge (majority of 3 votes), refined grading criteria and restricted network access. Scale says v1.1 scores aren't directly comparable to v1.0, so the v1.0 boards stay separate.
