Available now means you can buy and install it today. Only the Risk Investigation Agent carries this label.
Running means it is used in real compliance work we deliver, and its behaviour is settled, but it is not sold as a standalone product yet.
In build means it is a prototype. It runs and produces real output, but its contracts may still change, so we would not have you depend on it unsupervised.
The labels describe what is true rather than what we hope will be true shortly. A roster of nine cards with no legend would imply nine finished products, which is why the legend sits directly under the roster rather than behind a tooltip.
