Make CI failures reproducible instead of mysterious. CI Reproducibility & Compile Toolkit combines five complete tools that keep machines, packages, metadata, tests, and conditional compilation aligned.
**Complete tools included**
- Build Environment Drift Guard
- Clone-Safe UPM Guard
- Meta Commit Guard
- Test Flake Doctor
- Platform & Define Compile Matrix Guard
Use the tools independently or together: lock the expected environment, verify cloned package resolution, catch broken metadata before commit, rank flaky tests from history, and compile the reachable platform/define matrix without switching build target.
Each tool keeps its own focused workflow, reports, samples, and documentation. No external account or hosted service is required.
