RESOLVED. Root cause was a self-heal cron entry I'd added to /boot/config/plugins/dynamix/nextcloud.cron four days earlier — its OR-fallback (docker exec ... || mkdir -p /mnt/user/appdata/...) ran during boot when Docker wasn't up yet, polluting rootfs before shfs could mount. emhttpd then silently skipped shfs invocation as a safety measure. Removed the dangerous cron entry and shfs mounted cleanly on the next reboot. Lesson: any cron touching /mnt/user/ paths must guard against the boot-time race since crond starts before Docker. Had to dig through every change I made in the last 2-3 weeks one-by-one and try re-voting after removing each of them. Finally figured it out.
