ArgoCD Guardrails - Non Default Project

Non Default Project

argocd.non-default-project

Requires Applications to belong to a named AppProject rather than the permissive built-in default project, and (optionally) to a project on an allow-list. Scoped AppProjects bound what an Application may deploy and where — an ArgoCD-specific tenancy boundary.
