nit: add a short local comment as to why this is commented out. Maybe point to comment at top of file.

nit: You might also leave a note as to why this is necessary in the first place. It's not necessarily obvious why "https://" might need to be prefixed at the beginning.
There was a problem hiding this comment.
Also, consider checking for any URI scheme rather than "https://" specifically. So you don't end up with strange URIs like "https://http://example.com/..." if the user enters "--source http://example.com"

This PR does two things in order to achieve GCB provenance compatibility:
definedInMaterialfield. Until GCB updates their provenance generation, this will have to do.v0.3does not necessarily produce level 3 provenance, and we can only guarantee the provenance requirements (up to non-falsifiability for v0.3). We should definitely prioritize a versioning option in the future that would disallow generating provenance in a lower level mannger.Adds testcase for the JSON marshalling issue and the GCS Buckets.
