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.

## Known limitations (2026-08-06)

Three gaps are open against this article's own positioning as a persistent sovereign
vault, and are load-bearing for anyone evaluating the design today:

- **Storage is not yet persistent.** The deployed guest's virtio-blk storage device is
  never actually mounted. A guest reboot wipes all data — a direct, current gap against
  the "persistent WORM vault" positioning this article argues for.
- **Graceful shutdown is broken.** Shutdown via QMP (QEMU Machine Protocol) is documented
  as broken: the guest has no ACPI or power-button device to receive a shutdown request.
  Redeploys currently hard-kill the guest, with no checkpoint guarantee at the moment of
  kill.
- **Nothing anchors or signs the ledger yet.** The integrity-anchoring companion service
  has been failing since 2026-08-01, and checkpoint signing is deliberately left unset at
  this baseline. The WORM ledger runs, but no external anchor and no signature currently
  attach to its checkpoints.

These are the deployed build's current, factual limits. The boot and inference
verification above is real and current; the vault's
persistence, availability, and ledger-anchoring guarantees are not yet delivered.
These same limitations — storage not yet persistent, graceful shutdown broken, nothing
anchoring or signing the ledger yet — are load-bearing for anyone evaluating the design
today. Rather than restate them here, see [[totebox-os]]'s own **"A known limitation —
data persistence inside the seL4 guest"** section for the canonical, single-sourced
version of this fact.

Every organisation that relies on a third-party platform to store its records is making an implicit wager: that the platform provider will remain solvent, accessible, and free of security failures for as long as those records matter. [[totebox-os]] is designed for operators who have decided that wager is unacceptable.
