+Conversation Chain and Threading Validation Test
+
+This test validates that:
+1. Multiple tool invocations create proper parent->parent->parent chains
+2. New conversations can be started independently 
+3. Original conversation chains can be resumed from any point
+4. History traversal works correctly for all scenarios
+5. Thread relationships are properly maintained in Redis
+
+Test Flow:
+Chain A: chat -> analyze -> debug (3 linked threads)
+Chain B: chat -> analyze (2 linked threads, independent)  
+Chain A Branch: debug (continue from original chat, creating branch)
+
+This validates the conversation threading system's ability to:
+- Build linear chains
+- Create independent conversation threads
+- Branch from earlier points in existing chains
+- Properly traverse parent relationships for history reconstruction
