+"""Live e2e: a project allow-listed to "all-team-models" inherits the team's models.
+
+The Admin UI writes ``all-team-models`` into a project's model list when a user picks
+"All Team Models". The contract is that the project then allows exactly what the
+parent team allows, so a project-scoped virtual key can call any model the team can
+call and is still denied a model outside the team's list. Regression coverage for a
+project-scoped key being denied with ``project_model_access_denied`` while naming a
