+# Do not attempt a seat before its generated env exists. `install` enables this
+# unit (WantedBy=default.target) but on a roster-v2 fleet the reconciler owns the
+# generated env, so between `install` and the first `apply`/`regen --write` there
+# is a boot window where ExecStart would run against an absent env file and the
+# launcher would fail the unit. A skipped unit is the honest state for "enabled
+# but not yet configured"; systemd re-evaluates the condition on every start, so
+# the seat comes up on the next start once the reconciler has written env.
