Measured on demo-felhom (N100, 16 GB): 61 apps deployed and removed through the
product, sampled every 5 s; heavy apps with one real action (Immich 200 photos,
Jellyfin transcode, Paperless OCR, Nextcloud 500 MB, ...). sizing.json for the
estimator (tools/build_sizing.py), SIZING.md with the proposed minimum machine,
METHOD.md. Power is RAPL CPU-package only (no meter). R-993 asks the operator to
approve the minimum machine; R-994 lists catalog limits/requests that are too low;
R-995 records leftover unnamed volumes after removal. R-231's dated check measured:
dooplex-backup.service success, journal green.
