Awesome!

Yep, just sent it.

Do you mean you can't run executables, or that having the Python stack in
there as well is not possible/burdensome? Just curious.

There's no documentation available for this level, yet, just the code.

However, yes, it's just JSON submitted to a PubSub topic, currently, and the
schema is exactly as output by "kcidb-schema".

Please validate JSON fully before submitting to the PubSub topic
("kcidb-validate" could help you start). We don't have error reporting to
submitters from the server side yet, we'll have to read the logs to find out
what happened, if it breaks :)

I sent you the project/topic names in the message with the credentials.

Oh, and we would definitely appreciate a contribution of the Go submission
module, if you make one :)

Yes, there's a "playground" instance, details are in the message with the
credentials. You can see the results on the "playground" dashboard, and query
them from the "playground" database with "kcidb-query".

Do you mean "deploying the dashboard"?

Excited to have you join the effort!
