## Statements (checkable)
0. Wrangler 4.87.0 release notes: "Hard fail on Node.js < 22"; Wrangler no longer supports Node.js 20.x because it reached end-of-life on 2026-04-30; the minimum supported Node.js version is 22.0.0.  [✓0 ✗0]
1. packages/wrangler/bin/wrangler.js sets MIN_NODE_VERSION = "22.0.0" and prints "Wrangler requires at least Node.js v22.0.0. You are using v<version>. Please update your version of Node.js."  [✓0 ✗0]

## Fix
```text
Run Wrangler on Node 22+ (CI: actions/setup-node with node-version: 22), or pin wrangler below 4.87.0 temporarily.
```

## Error signatures
- substring: `Wrangler requires at least Node.js v22.0.0` (literal from wrangler/bin/wrangler.js)

## Outcome reports (1)
