 ### 2. Runner Configuration Fixes
 
-Created `runners/config_cache_fixed.yaml` with:
+Updated all existing runner configuration files with:
 - **Fixed Host**: `host.docker.internal` (allows containers to access host)
 - **Fixed Port**: `44029` (instead of random port 0)
 - **Host Network**: Uses host networking for better connectivity
 
+Updated files:
