xint-install-path-versioned-releases-with-current-symlink
xint should be installed at /opt/infra/xint/releases/<version>/ with a current/ symlink following the VPS infra pattern. The global launcher at /usr/local/bin/xint executes via Bun from the symlinked path. This pattern enables atomic version rollbacks by simply updating the current/ symlink without service interruption.
