radio-box (INSTALL_DIR=/home/pi/node-26, owned by pi) failed every update: root's git refused the repo as 'dubious ownership', so origin read as '' and the origin check refused. Scope safe.directory to INSTALL_DIR via GIT_CONFIG_* env (command-line scope) for the updater process only. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
