⏱️ Estimated effort to review: 1 🔵⚪⚪⚪⚪

🔒 No security concerns identified

⚡ Recommended focus areas for review Compatibility The default OCP_VER value for non-OpenShift clusters is now hardcoded to a newer version. Please validate that the corresponding default IIB tag/image for this version exists and is accessible in the target registries, and that using this value won’t break installs on non-OCP clusters (where OCP version detection does not apply). OCP_VER="v4.21" OCP_ARCH="x86_64"

Explore these optional code suggestions:

Category	Suggestion	Impact
General	Enable environment override of default version Make the OCP_VER variable configurable by allowing it to be set from the environment, with "v4.21" as the default value. .rhdh/scripts/install-rhdh-catalog-source.sh [650] -OCP_VER="v4.21" +OCP_VER="${OCP_VER:-v4.21}" Apply / Chat Suggestion importance[1-10]: 6 __ Why: The suggestion correctly proposes making the OCP_VER configurable via an environment variable, which improves the script's flexibility over the hardcoded value in the PR.
