Review Change Stack

Walkthrough

The change imports Node.js crypto.randomInt and uses it in randomstring to select dictionary indexes instead of Math.random().

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to ead24

This change can make the browser UI build incompatible by introducing a Node-only crypto dependency through a shared utility. The PR is not merge-ready until the utility is made browser-safe or the random-string implementation is isolated to Node-only code.

There were issues while running some tools. Please review the errors and either fix the tool's configuration or disable the tool if it's a critical failure.

🔧 ESLint

If the error stems from missing dependencies, add them to the package.json file. For unrecoverable errors (e.g., due to private dependencies), disable the tool in the CodeRabbit configuration.

Keep framework/utils/lib/common.ts browser-compatible.

packages/ui-default/entry.js imports api.ts, which re-exports common.ts. The browser Webpack 5 configuration has no Node fallback, so node:crypto makes the UI bundle incompatible. Move randomstring to a Node-only module or provide a browser-safe implementation.
