Pull Request #758 was submitted for work in the 644-cicd-validate-failure-argument branch which completes this Issue. However, another Pull Request #714 also contains work that implements a fail-on-warn feature. This can be observed in the following locations:

• python/src/aac/plugins/check/init.py lines 21, 26
• python/src/aac/plugins/check/check_impl.py lines 19, 207-208
• docs/source/project_documentation/plugins/check.md lines 15, 28
• python/src/aac/plugins/check/checkaac.aac line 17

For this reason, I will cancel PR #758, since this Issue is already addressed in PR #714.
