## Files reviewed

- `dist/diff.js` (safe): No malicious patterns detected; the code is a standard diff/patch library (jsdiff) with no network, filesystem, process, or dynamic code execution risks.
- `eslint.config.mjs` (safe): Cleared by Jev triage; no further analysis needed
- `libcjs/convert/dmp.js` (safe): Cleared by Jev triage; no further analysis needed
- `libcjs/convert/xml.js` (safe): Cleared by Jev triage; no further analysis needed
- `libcjs/diff/array.js` (safe): No malicious patterns detected; the code is a standard TypeScript-compiled array diff utility with no network, filesystem, process, or dynamic execution behavior.
- `libcjs/diff/base.js` (safe): No malicious patterns detected; this is a legitimate diff algorithm implementation.
- `libcjs/diff/character.js` (safe): No malicious patterns detected; the code is a standard character diff implementation with only local module imports and no network, filesystem, or process activity.
- `libcjs/diff/css.js` (safe): No malicious patterns detected; the file implements a simple CSS diff utility with no suspicious network, filesystem, process, or dynamic code execution behavior.
- `libcjs/diff/json.js` (safe): No malicious patterns detected; the code implements JSON diffing and canonicalization without network, filesystem, process, or dynamic code execution behavior.
- `libcjs/diff/line.js` (safe): No malicious patterns detected; this is a standard line-diffing utility from the jsdiff library with no network, filesystem, process, or obfuscated code.
- `libcjs/diff/sentence.js` (safe): No malicious patterns detected; the code is a standard sentence-level text diff implementation with no network, filesystem, process, or dynamic execution behavior.
- `libcjs/diff/word.js` (safe): No malicious patterns detected; this is a legitimate word-diff library implementation with no network, filesystem, process, or obfuscated code.
- `libcjs/index.js` (safe): No malicious patterns detected
- `libcjs/patch/apply.js` (safe): No malicious patterns detected; the code is a pure unified diff patch application utility with no network, filesystem, process, or dynamic code execution behavior.
- `libcjs/patch/create.js` (safe): No malicious patterns detected; the code is a standard unified diff/patch generation utility with no network, filesystem, process, or dynamic execution capabilities.
- `libcjs/patch/line-endings.js` (safe): No malicious patterns detected; the code only performs pure line-ending normalization on patch data with no I/O, network, process, or dynamic execution.
- `libcjs/patch/parse.js` (safe): Cleared by Jev triage; no further analysis needed
