mba-deploy-pod.sh 784 fix: trash on whey errors 'requires at least 1 arg(s), only received 0' - trap not actually passing the dir

proxy-mba-w-cc measured 2026-10-09 01:08 ART on the patch-232 mirror: trap fires 'trash -- "${TEMP_BASE:?}"' but gtrash reports 0 args received. No leak this run only because the dir was already gone by another means. Needs live diagnosis on whey (type trash; trash --version; manual repro with a throwaway dir) before another blind fix - this is the second cleanup-trap miss in a row (783 command rm, 784 whey rm-shim), root cause not yet actually confirmed live.
