## Public findings

### 1. Low: Scripts Present

Package declares npm scripts.

### 2. Low: Filesystem
- **Category:** Source
- **Confidence:** 70.0%

Package source references filesystem APIs.

### 3. High: Package Source Clone Identity Mismatch
- **Category:** Supply Chain
- **Confidence:** 88.0%
- **Path:** demo/runkit.js
- **Public source:** [View source](<https://unpkg.com/@depup/memfs@4.68.0-depup.0/demo/runkit.js>)

Package source closely matches a different published package identity; review for dependency-confusion or copied-code abuse.

Public source snippet (untrusted):

```javascript
matchType = package_source_clone_identity_mismatch
matchedPackage = memfs@4.68.0
matchedPath = demo/runkit.js
matchedIdentity = npm:bWVtZnM:4.68.0
similarity = 1.000
shingleOverlap = 7
summary = source files closely matched a different published package identity
```
