Some checks failed
Architecture Governance / architecture (push) Has been cancelled
There was no CD: pushing to main deployed nothing, and deploys were a manual copy onto the server. This adds the missing half. - .github/workflows/deploy.yml - build, upload to a per-commit release directory, swap the symlink atomically, reload nginx, verify over HTTP. The swap only happens after the upload is verified to contain index.html, so a failed deploy leaves the previous release serving. - scripts/deploy/server-setup.sh - idempotent one-time provisioning: nginx, certbot, ufw, and a key-only deploy user whose sole sudo right is "systemctl reload nginx". - scripts/deploy/add-domain.sh - per-domain server block plus TLS issuance, run once a domain's A record resolves to the server. - docs/DEPLOYMENT.md - setup order, required CI secrets, rollback, limits. Also adds .gitattributes: the shell scripts were being checked out with CRLF endings, which makes bash fail on the shebang line on Linux. Host keys are pinned via DEPLOY_KNOWN_HOSTS rather than trusted on first use. No credentials are committed; all four deploy secrets are supplied by CI.
