+# site.yml — IEC 62443-3-3 SL2 Compliance Validation
+#
+# Entry point for the compliance testing framework. This playbook:
+#
+#   1. Runs against all hosts in the inventory
+#   2. Gathers facts first (ansible_date_time, ansible_user_id, etc.)
+#   3. Executes each FR suite as a named task inside an ignore_errors block
+#   4. Invokes library/report.yml to aggregate test_results[] and write JSON
+#
+# Usage:
+#   ansible-playbook -i inventory.ini playbooks/site.yml --limit <host> -K
+#   ./run.sh --limit <host> -K
+#
+# Adding a new suite:
+#   Copy the block below, change the name and include_tasks path:
+#
+#     - name: "Suite: FRN — Category Name"
+#       block:
+#         - ansible.builtin.include_tasks: suites/frN_category.yml
+#       ignore_errors: yes
+#
+# Variables:
+#   report_dir: Where JSON reports land (default: ./reports, created locally)
