PointSav Documentation

The engineering library for the PointSav platform — operating systems and services for regulated businesses that own their data, their AI, and their record-keeping outright. Where the monorepo holds the code, this wiki holds the reasoning: architecture, services, security, and the governance commitments that bind future development.

QEMU process and handles graceful shutdown via the QEMU monitor socket.

Each active service is reachable only on the guest's own local network interface,
port-forwarded from the host; none of these are exposed addresses a reader outside the
platform's own infrastructure could reach. A systemd unit on the host manages the QEMU
process for the guest and handles graceful shutdown via the QEMU monitor socket.
