Calibre Content Server deployed on Dankserver (192.168.0.235:8084) with four critical traps discovered: LS image 9.15.0 is desktop not headless, internal port 8080 is nginx so use 8090, default auth is Digest not Basic, and echo-piped passwords include trailing newline. Calibre-Web 0.6.27 confirmed to have no generic OIDC; guard chain is the only SSO path.
