FINDINGS ░▒▓

infoSuspicious files are not reachable from entry pointsFlagged files exist but are not imported by any entry point. They may be dead code, tests, or attack payloads triggered by another mechanism.+2

warningExtremely long lines (>1000 chars)Very long lines in source files (not minified bundles) can hide malicious code.perf/readUtf8.js+4

criticalString-array obfuscation detectedCode resolves its string literals through a rotating string-array decoder — many `name(0xNNN)` index calls that reconstruct hidden strings at runtime. This is the structural signature of javascript-obfuscator regardless of the variable-naming scheme, so it fires even when mangled identifiers (e.g. `j5`, `jM`) are used to evade _0x-based detection. Commonly used to hide malware from code review.test/node/test-buffer-alloc.js

  const b = Buffer.from([0xde, 0xad, 0xbe, 0xef]);
  let s = String.fromCharCode(0xffff);
  b.write(s, 0, 'latin1');
  assert.strictEqual(0xff, b[0]);

Scores are heuristics. A “safe” verdict means no known-malicious patterns were found — clever malware can look boring. Wrong verdict? Flag it above; confirmed false positives become regression tests.
