cubicweb #343637 possible coherency violation in changing relation [open]

You can modify a relation and break the coherency for some schema. The problem is there is no constraint check on the relations other than the modified one.

syt adds: eg for instance redirect a ticket already affected to a version to another project. It's then affected to a version from a project different than the ticket's version.

Cubicweb should provide a way to see that a constraint implies multiple relation and check them whenever one of those relations change.
