```
likely benign LLM, confidence 0.97 A 5630-character union type alias in a Babel type declaration file.
Reasoning
This is a generated TypeScript declaration file for @babel/types, where a single union type alias is written on one line. Long lines in .d.ts files are a formatting artifact with no executable content.

```
likely benign LLM, confidence 0.97 A 4947-character union type of AST node names in Babel's type declarations.
Reasoning
This is a generated Babel type declaration containing a long union of AST node type names. It is declarative typing only and does not execute anything.

likely benign LLM, confidence 0.97 A 2542-character union of Babel AST identifier types in a declaration file.

```
likely benign LLM, confidence 0.97 A 28227-character export statement re-exporting Babel constants and types.
Reasoning
A generated re-export list of Babel type and constant names in a declaration file. Long export lines are normal for the generated barrel output of @babel/types.
info ~~warn~~ → info by review error-stack-inspection lib/index.js:2877:16

`includes` called on `new Error().stack` — string-matching the call stack is the structural shape of sandbox/analyzer detection (ast pass, confidence 0.85)
```
          const error = new Error("NumericLiterals must be non-negative finite numbers. " + `You can use t.valueToNode(${val}) instead.`);
          if (!new Error().stack.includes("regenerator")) {
            throw error;
          }
```
likely benign LLM, confidence 0.80 Babel's numeric literal validator checks whether the call stack includes 'regenerator' before throwing a non-negative-number error.
Reasoning
This is the NumericLiteral validator in @babel/types. It inspects the stack only to decide whether to throw an error for a regenerator-generated literal, which is a compatibility exception rather than a sandbox or analyzer check. It does not run code or alter behaviour outside the error path, so it looks like a legitimate workaround, though the stack-string match is an unusual pattern.

```
likely benign LLM, confidence 0.97 A 25094-character export statement in the bundled @babel/types index.
Reasoning
A generated re-export statement of Babel constants and builder names in the bundled JavaScript. Long lines of this kind are a bundler/codegen artifact with no obfuscation or malicious behaviour.

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.
