real_ssh was a separate service name pointing to the same template and behaviour as ssh. Merged them: ssh is now the single real-OpenSSH service. - Rename templates/real_ssh/ → templates/ssh/ - Remove decnet/services/real_ssh.py - Deaddeck archetype updated: services=["ssh"] - Merge test_real_ssh.py into test_ssh.py (includes deaddeck + logging tests) - Drop decnet.services.real_ssh from test_build module list
