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.

editorial(systems): fix os-totebox-service-pd-model self-diagnostic narration (Track-B) — confirmed real 7-PD table against moonshot-toolkit/examples/os-totebox.toml (watchdog-pd/network-pd names match exactly), article already deeply hedged with an existing Known-limitations section; dropped 'fabricated risk' self-diagnostic phrasing per register-documentation.yaml, content otherwise accurate; register-clean EN+ES

[[os-totebox]] is designed to be the Sovereign WORM Data Vault tier of the [[topic-three-binary-architecture|three-binary architecture]], intended to run as a Type I bare-metal OS on top of the [[sel4-microkernel-substrate|seL4 microkernel]] — no shell, no root process, no init system, no package manager — once the Phase H1 seL4 image ships. In that end-state design, every service that handles durable data becomes a seL4 Protection Domain (PD): a hardware-enforced isolation unit whose capability set is fixed at build time and cannot be extended at runtime. This article explains what that design means, why it takes the shape it does, and how two planned tools — moonshot-sel4-vmm and [[moonshot-toolkit-build-orchestrator|moonshot-toolkit]] — are intended to turn ordinary Rust service binaries into a formally verified PD graph.
