Viktor asked to self-host the DJI flight-log analyzer for his DJI Mini 4 Pro (his fork ViktorBarzin/drone-logbook -> upstream arpanghosh8453/open-dronelog). Upstream ghcr image with Keel auto-upgrade, DuckDB data on an encrypted proxmox-lvm PVC (GPS traces = sensitive), NFS /sync-logs drop folder imported every 8h, daily backup CronJob to /srv/nfs/drone-logbook-backup (vaultwarden pattern), Authentik-gated ingress, PROFILE_CREATION_PASS from Vault via ESO. Design + plan in docs/plans/; service-catalog updated.
