Backend changes:
- transformers.py: QR container now sized to actual qr_bbox + 8% padding
(was fixed at 45% of card width). When QR was wider than 45% of card,
the leftover-pixel branch color-remapped QR pixels outside the
container, breaking the scan. New container always encloses qr_mask.
- main.py: persist input + output + json metadata under
$UPLOAD_DIR/<airline>/<ts-uuid>-{input.<ext>,output.png,*.json} for
future training. Failure to save is logged, never breaks the API.
Infra:
- New PVC priority-pass-uploads (1Gi proxmox-lvm-encrypted, 10Gi
autoresize cap) — encrypted because boarding passes contain PII.
- Deployment strategy → Recreate (RWO requirement).
- Volume + volumeMount + UPLOAD_DIR env on backend container.
Applied via kubectl (TF state for this stack is empty — see prior
commit). New pod priority-pass-77956b64fb rolled out, PVC bound,
test transform succeeded, sample written to /data/uploads/ryanair/.
