+# The cockpit-waiter (cockpit-waiter.html) polls the sidecar's :8080/health
+# with a 20s deadline. verify-package.sh:31 asserts the waiter file is STAGED
+# but nothing exercises it at runtime. First real user report of "cockpit
+# forever spinning" would be the first signal — same failure class as v150.0.6
+# gate false-negatives.
+#
+# This job launches BearBrowser headless via xvfb against the tip Linux
+# nightly, navigates to the cockpit URL, and asserts the waiter resolves
+# within N seconds. Independent of nightly-linux.yml's runtime audit so it
+# fails visibly on its own if the waiter regresses.
