how to delineate non-cosmos chains, or tag chain network types

[pyramation]

I'm trying to figure out how to detect from the structure if a chain is a non-cosmos chain, but realizing it's purely based on the folder structure? Was there a discussion for how to delineate in the actual json if it's cosmos or not? If this is to ever live in a database or a chain, it should have some delineating field.

I attempted to look at all assetlist.json files and see if a sibling chain.json exists, only 2 chains not in non-cosmos showed up, you can test for yourself:

#!/bin/bash

# Find all assetlist.json files
find . -name "assetlist.json" | while read -r assetlist_path; do
  # Get the directory of the assetlist.json file
  dir=$(dirname "$assetlist_path")
  
  # Check if chain.json exists in the same directory
  if [[ ! -f "$dir/chain.json" ]]; then
    # If chain.json does not exist, print the directory path
    echo "$dir"
  fi
done
