info ~~warn~~ → info by review dynamic-import benchmark/index.js:19:29

`require` called with a non-literal specifier (ast pass, confidence 0.60)
```
  let func = stringifyPackages[name];
  if (func === true) func = require(name);

  suite.add(name, function() {
```
likely benign LLM, confidence 0.90 A benchmark script calls require with a variable package name taken from a local table of stringifier packages.
Reasoning
The require call uses the loop variable name, which iterates over a fixed set of benchmark package names defined in the benchmark harness. This is a dev-only benchmark script loading known stringifier packages; no decoding, network, or process execution is involved. Dynamic require here is a normal benchmarking pattern rather than obfuscation or malicious behavior.

Reproduce This Scan

Run disclude locally to verify. These commands scan the published file; the "new in this release" marks come from comparing it with the previous release's file, which they don't repeat. Add --format sarif for SARIF output. Add --llm (with an API key in the environment) to include the LLM review.
