File Download

You can download a file from an authenticated app filesystem path by using session-aware URL construction that enforces read permissions for user layer paths like `~/` and `/L0/`, returning 401/403 errors appropriately if access is denied.

The best way to export runtime-generated in-memory content like JSON or CSV is by creating Blob-based object URLs. This allows the browser to directly download dynamically generated text, CSV, JSON, and binary data like PDFs.

To handle CORS issues when downloading files from an external URL, you can use a server-proxied fetch to retrieve the remote resource and stream the response directly into a browser download, bypassing external access-control restrictions.

Yes, you can export admin workflow artifacts like CSV and JSON dumps from user or group layers. The skill is designed for operators to export generated reports and documents stored within these authenticated app filesystem routes.

Your external file download fails with browser security constraints due to CORS restrictions. The skill resolves this by fetching external files through a server proxy first, then streaming the response into a browser download.
