On a fresh mc_data volume the minecraft service crash-loops with
"AccessDeniedException: /data/kubejs/config" (ConsoleJS.STARTUP null NPE):
Docker auto-creates the bind-mount parent /data/kubejs as root:root, but
the itzg container runs as uid 1000, so KubeJS can't create its writable
siblings (config/cache/generated/logs). Only bites fresh worlds — cochi's
aged volume predates the ro submounts and is already 1000-owned.
Fix (durable): chown 1000:1000 /data/kubejs once, then restart.
- plan/22-migration.md: Troubleshooting section with symptom + fix.
- migrate-import.sh: manual tail now flags it with the exact commands.
Hit + resolved during the cochi->oxps migration.
