+        # that host shapes inbound traffic; this step killed it at 600s, so the
+        # script's budget could never be spent and the shorter of two
+        # disagreeing limits always won. Every release since has ended the same
+        # way — `The action … has timed out after 10 minutes`, GitHub's eight
+        # assets uploaded in seconds and GitCode's three large ones cut off,
+        # with only the small `.sha256` files through. v2026.8.25.1 and
