If “Fail Open” mode is active (Pricing | Cloudflare Pages docs), I understand from the documentation that my _worker.js file would not be seen
as a static asset, but what about if my _worker.js file imports some others files?

For example, given the following _routes.json:

{
  "version": 1,
  "include": [
    "/*"
  ],
  "exclude": [
    "/assets/*",
    "/"
  ]
}

And the following directory structure:

├── _routes.json
├── _worker.js
├── assets
│   ├── chunks
│   │   └── some-public-file.js
│   └── static
│       └── some-public-file.css
├── index.html
└── server
    └── imported-by-_worker.js

My question is, will cloudflare leak my server-side source code when an out-of-quota request is made to /server/imported-by-_worker.js?
