+
+* feat: ESO integration + change default projects path to apps/ (by @patrickleet)
+
+  ESO integration for ArgoCD repo credentials:
+  - ExternalSecret pulls GitHub App creds from AWS Secrets Manager
+  - Projects/Crossplane apps gated on repo creds when ESO enabled
+  - Usage protects deletion ordering
+  - 5 new unit tests (17 total, all passing)
+
+  DX improvements:
+  - Default projects.path changed from .gitops/deploy to apps/
+  - Works with hops-ops/gitops-template for intuitive repo structure
