The page claimed an env-var interface (COPAY_PASS/COPAY_MODE) and a /data volume convention that this image does not implement: the ac edition consumes accounts and volumes as argv flags (-a USER:PASS, -v SRC:DST:PERMS), serves the LUKS array at /w, and answers HTTP 500 with its own error page when zero volumes are configured. Image ref corrected to copyparty-ac (bare latest tag does not exist on ghcr).
