+# Dependency Analysis
+
+## Purpose
+
+Analyze dependencies and execution assumptions before changing scripts, automation or future backend design notes.
+
+## Rules
+
+- Identify whether the task affects frontend-only, documentation-only or platform-only areas.
+- Avoid importing template assumptions from unrelated stacks.
+- When in doubt, preserve the current lightweight structure and document the dependency instead of implementing it.
