gstack_bun_incoming_hold (bin/gstack-bun-version.sh) is now the one pre-advance check: the auto-updater calls it before its fast-forward and /gstack-upgrade's git path calls it after fetching. Below the incoming release's floor the upgrade stops with BUN_TOO_OLD and the checkout, VERSION and installs stay untouched. Vendored installs were already safe: setup refuses before writing and the swap restores the previous install.
