• Build tools for coding agents to reproduce the failures and artifacts needed to diagnose regressions and verify fixes.
• Root out flaky tests so a failing build always reflects a real bug.
• Make our 3D editor more testable so we can automatically test our users' CAD workflows.
• Help other engineers write testable code and durable tests to go with every feature.
