+# Determines if conditions are met for running subsequent jobs on a Pull Request.
+#
+# !! IMPORTANT !!
+# This workflow RELIES on being called from a parent workflow triggered by
+# a `pull_request` or `pull_request_target` event. It uses `github.event`
+# to access PR details.
+#
+# It checks if all the following conditions are TRUE:
+# 1. The PR is NOT from a fork (i.e., it's an internal PR).
+# 2. The PR has been approved by a maintainer (`is_pr_approved_by_maintainer`).
+# 3. The PR's source branch does NOT match an excluded pattern.
+# 4. The PR includes relevant file changes (`paths_filter_patterns`).
+#
+# It outputs `should_run` as 'true' if ALL conditions pass, 'false' otherwise.
