usc ACK #811 diagnosis: upgrade-guard 40/41, only Part 7 negative-control leak demonstration differs under busybox/root; real CWE-59 assertions pass. USC retains sole repair ownership. Preserve the non-tautological negative control and reproduce inside the CI Alpine image before push; do not weaken/delete it. Any current-head review is non-transferable: repair head requires fresh durable exact-head independent RoR and terminal-green exact-head CI before queue/merge.
