HAProxy Manager Build and Push / Build-and-Push (push) Successful in 1m13s
- Remove invalid ACL combination syntax (can't use 'or' to combine ACLs) - Use multiple http-response lines instead (each line is OR'd together) - Each line checks specific scan pattern with 404 AND not legitimate assets - Simplify logic to be HAProxy 3.0 compatible This fixes the config parsing errors while maintaining the same detection logic - only counting suspicious script/config 404s, not missing assets. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
