Inputs, outputs, and verification

The workspace accepts formats relevant to curl-to-javascript converter, preserves the original material in a separate pane, and produces reviewable output. Standards-sensitive results should be tested against the runtime, provider, protocol, or policy that will consume them.

Privacy, safety, and operational limits
