 Cobble ships as a multi-arch container image and a single `install.sh`.
 The repository starts private and is made public at the launch gate below.

+before v1.0.0 is an alpha release: interfaces, the database schema and the
+settings may change between them, so a release that needs a migration step

A task in a workspace has the workspace's shared context, the worker's instructions and memory for that workspace, the project's files, and the workspace's computers as well as the worker's.
