CentOS Stream vs RHEL rebuilds: library-version parity for compiled workloads on RHEL 9
Constraint A production fleet runs RHEL 9.4 and must remain on that minor release for the current support cycle. Development and CI systems need a no-cost environment that matches the production user-space ABI as closely as possible, especially glibc, libstdc++, and kernel headers, so that C++ binaries built in CI behave identically when deployed.
