sglang-bisect-ci-regression

To find the root cause of a SGLang CI regression, extract failure signatures from scheduled runs and bisect the main-branch commit window. This process isolates the regression window and identifies candidate commits for review.

Bisection for GitHub Actions CI failures works by applying failures across main-branch commits to narrow down the regression window. It evaluates whether issues stem from code regressions, environment changes, or hardware-specific runner contexts.

Yes, you can reproduce CI test failures on a remote GPU host. The workflow analyzes runner and hardware context, then provides remote reproduction guidance and reproducibility steps when requested to verify the issue.

To start debugging a CI regression, you need to provide a failing test name or a CI URL. The workflow then collects exact error messages, failing test names, and involved models or configs to build a structured report.

Yes, it differentiates between code regressions, environment changes, and hardware-specific issues. By analyzing runner and hardware context alongside temporal bisection, it categorizes the failure source and generates a targeted remediation plan.
