Script	What it does
`setup.sh`	The production binary installer, served from `install.mulgadc.com`. Installs deps, users, sudoers, files, systemd units, logrotate and udev rules. `SETUP_STAGES` runs a subset; `ISO_BUILD=1` runs it inside the ISO builder's chroot.
`setup-ovn.sh`	Bootstraps a compute node for OVN VPC networking: installs OVN/OVS, creates `br-int`, configures the WAN bridge (bridged, DHCP, or routed-NAT uplink), sets the chassis identity, and applies overlay sysctls. `--management` also starts the OVN central services.
`install-node.sh`	Forms a multi-node cluster across hosts that are already running Spinifex: rebuilds the OVN database in clustered form, runs `spx admin init` on the first host and `spx admin join` on the rest, then verifies. The scripted form of install-multi-node. Destroys the joining nodes' logical network state and crypto — see its `--help`.
`dev-install.sh`	Full local dev setup through the production installer: builds from source, packs a tarball, runs `setup.sh`, initialises the cluster, and starts services under systemd.
`clone-deps.sh`	Clones or updates the viperblock and predastore checkouts alongside spinifex for cross-repo development.

Dev environment

Script	What it does
`reset-dev-env.sh`	Single-node reset: stops services, wipes `/etc/`, `/var/lib/`, `/var/log/` and `/run/spinifex`, rebuilds, reinstalls via `dev-install.sh`, and relaunches a smoke-test instance. Preserves the existing node/network topology from `spinifex.toml`.
`dev-env/*.conf`	Topology profiles for `reset-dev-env.sh --profile=NAME`, declaring which bridge carries the wan, lan and vpc planes: `single-nic` (all collapsed onto wan), `two-nic` (vpc folds onto lan), `three-plane` (a NIC each).

Verification and benchmarks

Script	What it does
`smoke-test.sh`	End-to-end sanity check on a running node: imports an SSH keypair and the Ubuntu AMI, then launches an instance. `--create-vpc` builds the VPC, gateway, subnet and routes first and tears them down after; `--nodes N` launches through a spread placement group so each instance lands on a different physical server. `TEST_GPU=1` adds GPU passthrough checks.
`verify-network.sh`	Asserts a node's datapath matches its declared planes — EIP reachability, which plane carries Geneve, and which interfaces services bind. Catches what `smoke-test.sh` cannot, since none of its traffic leaves the box.
`test-ddil-phase1.sh`	systemd-level smoke test for daemon-local-autonomy tier 1. Destructive on the local node: stops and starts `spinifex-nats` and restarts `spinifex-daemon`, restoring both via a cleanup trap.
`check-coverage.sh`	Fails the build if total Go coverage falls below the minimum threshold, excluding packages exempt from the requirement.
`diff-coverage.sh`	Coverage check scoped to changed lines only, against an auto-detected base ref (`HEAD~1` on main, `origin/main` on dev, otherwise `origin/dev`).
`run-bench.sh`	Launches a benchmark against running Ubuntu instances, auto-detecting the AMI for the host architecture. Tracks nbdkit and perf alongside the run.
`disk-performance.sh`	Runs an in-guest `fio` random 70/30 read-write benchmark. Installs fio and sysstat first.
`workload-performance.sh`	In-guest memory, disk, CPU and network workload test. Installs Go and runs the Badger test suite with jemalloc disabled and reduced parallelism.

Guest images

Script	What it does
`build-system-image.sh`	Builds a minimal system AMI (Alpine or Ubuntu) from a manifest. All customisation happens inside the libguestfs appliance, so the build touches no host block device, no host mount, and needs no sudo. `--import` also registers it as an AMI.
`publish-system-image.sh`	Converts a built raw image to compressed qcow2, writes the `.sha256` sidecar the catalog verifier expects, and uploads both to the R2 bucket behind `iso.mulgadc.com/system-ami/`.
`build-microvm-image.sh`	Builds the minimal Alpine kernel + initramfs used by the QEMU microvm machine type and the lb-agent, carrying haproxy (ALB) and nginx-stream (NLB) data planes.
`mkosi-build.sh`	Runs an mkosi system-image build inside the pinned builder container, so a runner needs only Docker and the toolchain cannot drift. `--image` names an output and expands to the right profile list.
`mkosi-publish.sh`	Publishes an mkosi-built image to R2 from inside the same pinned container — qcow2 conversion, `.sha256` sidecar, and upload.
`mkosi-common.sh`	Shared plumbing sourced by both mkosi scripts. Builds the toolchain image once, with the builder account matched to the invoking user so bind-mounted output is not written back as root.
`mkosi-builder.Dockerfile`	The pinned image-build toolchain. Debian-hosted regardless of target distro, since mkosi bootstraps the target from its own archive.

`images/` — per-image build inputs

Each subdirectory holds a manifest.conf, init scripts, and a setup.sh that build-system-image.sh runs inside the libguestfs appliance after packages and files are placed. *_test.sh files are shell unit tests for the helper of the same name.

Path	What it builds
`ecs-agent/`	The Alpine `spinifex-ecs-node` container-instance AMI (containerd + ecs-agent). `setup.sh` sets OpenRC exec bits, wires the CNI bin path, and applies the serial-console tweaks.
`ecs-agent-gpu/`	The Ubuntu ECS GPU container-instance AMI. Same CNI and containerd wiring adjusted for Ubuntu's package layout, plus the headless NVIDIA driver and nvidia-container-toolkit.
`eks-node/`	The unified Alpine EKS node AMI (K3s server or agent, selected at first boot). `setup.sh` installs the pinned, SHA-verified K3s binary and the role init scripts.
`eks-node-gpu/`	The Ubuntu EKS GPU worker AMI. Agent role only — GPU nodes never run the control plane — plus the NVIDIA GPU stack.
`rds-postgres/`	The `spinifex-rds-postgres` AMI. `setup.sh` sets exec bits on the OpenRC services and creates the root-only directory cloud-init drops the agent env file and gateway CA into.
`ubuntu-gpu-{amd,nvidia}-setup.sh`	Chroot setup for GPU-capable Ubuntu guest images: ROCm CLI tools and AMD firmware, or the DKMS-built headless NVIDIA driver. Guest-side only — host VFIO setup is `spx admin gpu setup`.

`images/eks-node/` — in-guest helpers

Installed into the EKS node AMI and run at boot or on a timer. All host communication goes through the AWS gateway over SigV4; the VM never speaks NATS directly.

Script	What it does
`eks-node-role.sh`	First-boot role selector. Reads `SPINIFEX_K3S_ROLE` from the cloud-init env file and enables the matching services — nothing is enabled at bake time.
`k3s-prestart.sh`	Server prestart: refuses to start on a restore-block marker, derives `config.yaml` from its skeleton, stages the konnectivity-agent and CoreDNS manifests, and waits for the token-webhook kubeconfig.
`k3s-agent-prestart.sh`	Agent prestart shared by the OpenRC and systemd units. Requires `K3S_URL` and `K3S_TOKEN`, then resolves the kubelet provider-id from IMDSv2 for EKS parity.
`k3s-first-boot.sh`	Runs once after the server is healthy: reads the node-token and admin kubeconfig, rewrites the kubeconfig server address to the cluster NLB endpoint, and publishes both to the host.
`konnectivity-server-prestart.sh`	Waits for the K3s CA and admin kubeconfig, mints the konnectivity serving cert, and writes the apiserver replica count for the caller to source.
`mulga-eks-addon-sync.sh`	Pulls staged managed-addon descriptors through the gateway, renders each bundle into the K3s auto-deploy dir, and reports per-addon delivery status back.
`mulga-eks-etcd-snapshot.sh`	Snapshots K3s embedded etcd to predastore. Installed into two crond periodic dirs and picks its tier — `frequent` or `daily` — from the dir it was invoked from.
`mulga-eks-k3s-recovery.sh`	Applies a control-plane etcd-quorum recovery directive before k3s starts. Pull-based and a no-op unless the reconciler escalated a wedged control plane.
`mulga-eks-state-report.sh`	Publishes server health (`healthz`, node count) to the cluster reconciler. The apiserver binds the VPC node-ip, which the host daemon cannot probe directly.
`mulga-eks-provider-id.sh`	Writes the K3s config drop-in supplying the metadata the EBS CSI driver needs from IMDS: provider-id plus the region, zone and instance-type labels.
`mulga-ebs-byid.sh`	Mints the EBS-style `/dev/disk/by-id` symlink the upstream EBS CSI node plugin resolves, from the virtio-blk serial. Alpine's busybox mdev has no eudev to do it.
`mulga-mgmt-net.sh`	Boot oneshot bringing a multi-NIC system VM's interfaces up by MAC from the QEMU fw_cfg netcfg blob, before cloud-init's network stage. cloud-init cannot reliably pick the right NIC out of two.
`mulga-vpc-mtu.sh`	Boot oneshot pinning the VPC data NIC MTU so flannel sizes its VXLAN overlay to fit the OVN geneve underlay. Otherwise large frames are silently dropped while handshakes pass.

Launch helpers

Script	What it does
`launch-gpu.sh`	Launches a GPU instance from the AMD or NVIDIA GPU AMI, selecting the AMI from the instance type's GPU brand. `--amd` / `--nvidia` override the detection.
`ecs-node-bringup.sh`	Launches an ECS container-instance VM. Renders the cloud-init user-data seeding the agent's control-plane config, IAM credentials and gateway CA — there is no ECS-specific launch API, by design.

`demo/` — GPU demo

Script	What it does
`deploy.sh`	Deploys and starts the four-instance GPU demo (dashboard, YOLO, Ollama, qwen3-vl) from the `*_IP` and `VIDEO_PATH` env vars.
`dashboard_server.py`	Serves the demo web UI and proxies the streams from the GPU instances.
`yolo_stream.py`	Runs YOLO detection over a video file, serving an MJPEG stream of annotated frames and an SSE stream of qwen3-vl scene descriptions.
