Introduces a data curation pipeline and repository sandbox generator for SWE agent training. Details methodology for sourcing repositories from PyPI, GitHub stars, and multimodal codebases, applying strict quality and activity thresholds. Describes the architecture of the code execution environment, which automates differential testing of Python repositories within isolated Docker environments, including dependency resolution, Dockerfile generation, LLM-based build failure fixes, test discovery, execution, and classification of test outcomes (FAIL_TO_PASS, PASS_TO_PASS).
