Hi @odh-devops-app[bot]. Thanks for your PR.

I'm waiting for a opendatahub-io member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

📋 Review Summary

This PR updates Tekton pipeline definitions by adding new baseline CPU pipeline runs for CentOS Stream 9 (c9s) and adjusting test group configurations. The YAML files are syntactically sound and correctly structured for Konflux CI integration.

🔍 General Feedback

• The added pipeline runs follow established Konflux conventions for pull request and push events.
• Workspace and parameter mappings correctly target the multi-arch container build templates.

Closing — superseded, please do not merge

This bot PR adds Tekton files we already have on main, from:

• RHAIENG-6389: feat(jupyter-baseline): integrate phase-1 jupyter-baseline wiring and build #4323 (jupyter baseline)
• RHAIENG-6391: feat(codeserver-baseline): integrate phase-1 codeserver-baseline wiring and build #4304 (codeserver baseline)
• RHAIENG-6390: feat(runtime-baseline): integrate phase-1 runtime-baseline wiring and build #4363 (runtime baseline)

Those use the *-ubi9-* pipeline files with build-args-file and *-ci-push.yaml. This PR adds duplicate *-c9s-* files without build-args-file, which causes the Konflux error:

no FROM statement found

Merging would duplicate pipelines and break notebooks-group-test.yaml.

Next steps: close #4346, #4355, and #4425; mark the Jira Tekton step done using the PRs above; don’t re-run the onboarder until odh-konflux-central templates are fixed.
