PointSav Documentation

Where the monorepo holds the code, this wiki holds the reasoning: architecture, services, security, and the governance commitments that bind future development.

Self-host a deployment

schema: foundry-doc-v1 title: "Self-host a deployment" slug: self-host-a-deployment short_description: "Boots the published os-totebox and app-orchestration-slm seL4 appliance images under QEMU, with configuration baked in at build time via device-tree bootargs, and verifies both come up healthy." category: self-hosting index_group: getting-the-platform-running content_type: how-to type: how-to quality: complete status: active audience: "Engineers (hands on keyboard); customer operators" last_edited: 2026-08-04 editor: pointsav-engineering paired_with: self-host-a-deployment.es.md research_trail: sources: [GUIDE-deploying-os-totebox-orchestration-appliances.draft.md (project-totebox, 2026-08-03), BRIEF-os-totebox-platform.md, .agent/binary-targets.yaml] verification_method: "consolidated with project-totebox's own staged, source-verified draft rather than re-derived independently"

Prerequisites

  • A host that can run QEMU for aarch64 (the appliance images target this architecture regardless of your host's own CPU)
  • The published os-totebox-loader.img and, optionally, app-orchestration-slm-loader.img from software.pointsav.com
  • A persistent disk image, created once and kept — an ext4-formatted raw file the guest mounts at /data
  • If you need non-default configuration (a specific orchestration endpoint, a Tier B license): the source repo, the Microkit SDK, and an aarch64 cross-compilation toolchain — the published images alone don't let you change configuration after the fact (see Step 3)

Purpose

Self-hosting a deployment means booting one or both of two independent, self-contained seL4/Microkit appliance images on operator-controlled infrastructure: os-totebox (the Sovereign WORM Data Vault — local DataGraph, corpus ingestion, Tier A operations) and app-orchestration-slm (the Yo-Yo broker chassis — health, fleet, and discovery endpoints; Tier B brokering requires a license). Each runs standalone by default; neither needs the other present to start.

Procedure

  1. Create your persistent disk, once:

    qemu-img create -f raw persistent.raw 2G

    This is where DataGraph state, adapter weights, and cached identity survive across restarts. Losing this file means losing everything the appliance has accumulated — it is not regenerated from the image.

  2. Boot the image via QEMU's -device loader mechanism (this is Microkit's own loader path, not the -kernel/-append path a general-purpose Linux VM would use):

    qemu-system-aarch64 \
  -machine virt,virtualization=on,secure=off -cpu cortex-a53 \
  -device loader,file=os-totebox-loader.img,addr=0x70000000,cpu-num=0 \
  -m size=2G -nographic -global virtio-mmio.force-legacy=false \
  -drive file=persistent.raw,format=raw,if=none,id=hd \
  -device virtio-blk-device,drive=hd,bus=virtio-mmio-bus.1 \
  -device virtio-net-device,netdev=netdev0,bus=virtio-mmio-bus.0 \
  -netdev user,id=netdev0,hostfwd=tcp::<host-port>-:<guest-port>

  3. If the published, generic image's default configuration is sufficient, skip to Step 4. Otherwise, understand this before you try to change anything: runtime configuration is baked into the image at build time, in the device tree's bootargs. There is no post-boot config file and no -append equivalent on this boot path. Changing configuration means rebuilding the image yourself, with your own foundry.* bootarg values, and replacing the published one — see the relevant keys below and the full rebuild procedure in the internal dogfood development guide (GUIDE-live-flow-doorman-orchestration-yoyo.draft.md, project-totebox).

    Key Appliance Purpose
    foundry.orchestration_endpoint os-totebox Chassis URL for Tier B brokering
    foundry.tier_b_subscribed os-totebox true to claim a paid subscription at registration
    foundry.yoyo_default_endpoint app-orchestration-slm Default Yo-Yo compute backend URL
    foundry.license_token / foundry.license_pubkey_hex app-orchestration-slm Ed25519-signed Tier B license

  4. Repeat Step 2 for app-orchestration-slm-loader.img if you want the Yo-Yo broker chassis too — it's an independent image with its own boot invocation, not a component started from inside os-totebox.

Expected outcome

os-totebox reaches a healthy, standalone state within seconds of boot, with or without app-orchestration-slm present — this degrade-not-refuse behavior is the intended design, not a sign of misconfiguration. app-orchestration-slm, if booted, answers health/fleet/discovery requests standalone; Tier B brokering itself stays disabled until a valid license is baked into a rebuilt image.

Verification

curl http://<host>:<totebox-port>/healthz       # os-totebox
curl http://<host>:<orchestration-port>/healthz  # app-orchestration-slm
curl http://<host>:<orchestration-port>/readyz   # license / fleet / circuit status

Rollback

Stop the QEMU process. The persistent disk (persistent.raw) is untouched by stopping the guest — restarting the same boot command resumes from the same accumulated state. To discard accumulated state entirely, discard the persistent disk file itself and create a fresh one (Step 1); there is no partial-reset mechanism short of that.

Next steps

Known limitations, as shipped (2026-08-03)

  • No automated update mechanism — a configuration change means a rebuild and a full image replacement, not a live edit.
  • The published images have not been through a customer-scale security review; treat as an early release.
  • Real GPU-scale training requires your own Yo-Yo compute backend — the images themselves don't include one.
