Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

SIGIL_HOME (Override the default ~/.sigil directory for keyfiles, audit log, and control socket.), SIGIL_CONTROL_SOCK (Override the default control socket path (~/.sigil/control.sock).).
