Claiming the system administrator role no longer grants access to every
application in the installation. Owning a tenant is what lets an administrator
administer it; entering the applications running inside it is a separate,
explicit grant that can be withdrawn again. Handing it out at claim time gave
every installation a standing administrator account inside every customer
application, which is the opposite of the boundary this product draws.
The behaviour suite now covers single sign-on between applications directly: a
second application on the same tenant must receive a code and identify the same
person with no sign-in page in between, once Go Loose already holds a session.
Also adds theme-token tests against the shared styling contract and store
coverage for application grants, and drops the redundant server and security
scheme declarations from the published specification.
