The owner copies infra/pi/ to the Kvitt Pi and runs it there (D-100); nothing
on the Mac connects to the Pis. compose stack of SPEC §10.2 with images
${KVITT_REGISTRY}/kvitt-{server,cert-sync,backup}, Caddyfile §10.5.2 verbatim,
.env.example with the OQ-3 values as CHANGE_ME placeholders, install.sh,
deploy.sh (backup before every deploy), bootstrap.sh, backup-now.sh,
install-apk.sh. cert-sync image and sync.sh (§10.5.1, tar stream for both
authorized_keys variants); backup.sh uploads with rclone copy --immutable and
deletes local files once both are confirmed on Drive (D-002); both sidecars
schedule with supercronic because busybox crond runs no jobs as non-root;
backup runs as uid 10001. .gitea/workflows/build-images.yaml from the owner's
example (not yet run); infra/build-images.sh and infra/publish-apk.sh (R8
mapping kept, version per §10.6) on the Mac; README checklist and RESTORE.md.

# Kvitt backup job image (SPEC §10.3, §10.9): alpine with sqlite, gzip, tar, rclone and backup.sh on a daily schedule.
|
|
# Versions resolved 2026-10-17: alpine 3.24.2 (Docker Hub official image, multi-arch index digest below);
|
|
# packages from Alpine v3.24 main/community: sqlite 3.53.4, rclone 1.74.1, tar 1.35, tzdata 2026e;
|
|
# 2026-10-18: supercronic 0.2.49.
|
|
# The scheduler is supercronic, not busybox crond: on the Pi the container runs as uid 10001, not root (README,
|
|
# "Backup uid"), and busybox crond cannot run jobs as a non-root user (checked 2026-10-18). See D-104.
