- `dist/cjs/errors.js` (safe): The file contains only error class definitions with no network, filesystem, credential, or dynamic code execution patterns.
- `dist/cjs/exports/abis.js` (safe): No malicious patterns detected; the file only re-exports ABI definitions from internal modules.
- `dist/cjs/exports/index.js` (safe): No malicious patterns detected; the file only re-exports symbols from local modules without any suspicious behavior.
- `dist/cjs/exports/zod.js` (safe): No malicious patterns detected
- `dist/cjs/human-readable/errors/abiItem.js` (safe): This file only defines three custom error classes extending a base error and contains no malicious patterns, network activity, file access, or dynamic code execution.
