The project has lived only as a folder on the Mac Studio and, briefly, as a transfer tarball. This is the first commit: the Express server and its web front end, the Capacitor iOS and Android wrappers, and the release and backup scripts. The repo is the source, not a backup of the machine. Left out on purpose, by the .gitignore files that were already in the tree: node_modules, build output, mobile/www (regenerated from server/public on every build), and server/data, which holds the live checklists and belongs on the NAS rather than in git. Every credential is excluded too — server/.env, the Play upload keystore and its properties file, the App Store Connect key and ios-signing.config. The one secret that was not in an ignored file was the NAS SSH password, hard-coded in build-deploy.sh and grepped back out of it by backup-to-drive.sh. Both now read it from the login keychain (service checklist-nas, account Christian), falling back to NAS_PASS in the environment, so rotating it is one keychain entry rather than a history rewrite.
