- Move SCRIPTS_DIR/DATA_DIR/STATE_DIR from appdata to /boot/config/plugins/varaverk - All state files now in STATE_DIR (no more /tmp or /boot/config root writes) - Bootstrap: Gitea-first clone with GitHub fallback, no array dependency - varaverk.cfg seeded with Gitea connection settings - .gitignore: add State_Files/, varaverk.cfg, varaverk-*.txz - Partnership/transcode/fallback scripts use STATE_DIR variables - PHP config.php: DATA_DIR/STATE_DIR constants, VV_SETUP_STATE_FILE dynamic - deploy.sh PROD_ROOT updated to plugin flash dir Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
