Custom Rules

Use --rules with a JSON file to add signatures without code changes:

{
  "rules": [
    {
      "framework": "MyFramework",
      "min_score": 60,
      "signals": [
        { "needle": "assets/myfw/config.json", "score": 60 },
        { "needle": "lib/arm64-v8a/libmyfw.so", "score": 40 }
