Restrict the Cloudflare token scope.
Set Account Resources to the deployment account instead of All accounts. Set Zone Resources to none or to the specific required zones instead of All zones. A compromised token created from this guide would otherwise expose unrelated accounts and zones.

Do not pass credentials in command arguments.
The guide places bearer tokens, provider tokens, S3 secret keys, and npm tokens in command-line arguments. Shell history and process inspection can retain these values. Use interactive input, standard input, or a documented environment-variable flow. The 0600 config-file permission protects persisted credentials but does not protect command-line arguments.

Do not make the S3 bucket public by default.
These instructions disable all public-access protections and grant s3:GetObject to Principal: "*", which makes every object in the bucket publicly readable. Keep public access disabled unless direct public S3 hosting is an explicit requirement, and document an isolated deployment bucket or a narrowly scoped public policy.

Create the nested test directories before writing files.
src/nested does not exist after creating longDir. Line 16 throws ENOENT, so test/run.js stops before it tests TAR extraction or static serving.
