feat(quota): seal per-account quota overrides behind a revision-guarded owner action (#1245)

Store the override record with a state field kept separate from the admin
wire type. Every set and clear is revision-guarded and refuses a sealed
record with Blocked, and every read of a sealed record, including
admission, returns Blocked. The read-failure fallback to configured limits
is unchanged.

Add Service.SealAccountOverrides, accepted only when IAM already holds the
account as TERMINATING. It creates the override bucket if needed after that
check, creates or updates the record as sealed, and succeeds only on a
leader-accepted write, returning its revision. awsgw serves it on
admission.v1.SealAccountQuotaOverride. Nothing calls it yet.

Replace the unwired delete-based CleanupAccount.

-#   spinifex-ecs-node       Alpine ECS container instance
-#   spinifex-eks-node-gpu   Ubuntu EKS K3s GPU worker (NVIDIA driver + toolkit)
-#   spinifex-ecs-node-gpu   Ubuntu ECS GPU container instance

+# How to Contribute
+
+We welcome contributions to Spinifex!
+
+Report security vulnerabilities privately through [SECURITY.md](SECURITY.md), not as a public issue.
+
+**AWS parity is the design rule.** When Spinifex's behaviour is in question, the answer is what AWS does. If you believe Spinifex diverges from AWS, state what AWS does and show it with a test or a reproduction against a running cluster.
+
+## Understanding the Codebase
+
+Every AWS call enters through a SigV4-authenticated gateway, is published to NATS, and is answered by the daemon that claims it. Start with these:
+
+| Doc | Covers |
+|---|---|
+| [`docs/DESIGN.md`](docs/DESIGN.md) | Architecture, request flow, daemons, storage integration, file layout. |
+| [`docs/COMMANDS.md`](docs/COMMANDS.md) | The `spx admin` CLI and the systemd units it manages. |
+| [`docs/coverage/`](docs/coverage/README.md) | Which AWS API operations each service implements. |
+| [`scripts/README.md`](scripts/README.md) | Install, dev-environment, and image-build scripts. |
+| [`docs/PACKAGE_BOUNDARY_MIGRATION.md`](docs/PACKAGE_BOUNDARY_MIGRATION.md) | ADR-0001 implementation inventory and incremental source moves. |
+
+User-facing docs are published at [docs.mulgadc.com](https://docs.mulgadc.com).
+
+## Development Setup
+
+These steps build Spinifex from source and run it as a single-node cluster, following the [Source Install](https://docs.mulgadc.com/docs/install-source) guide.
+
+### Prerequisites
+
+- **Ubuntu 26.04** or **Debian 13**, on x86_64 or aarch64
+- A host with hardware virtualisation (KVM) and `sudo` access
+- The host's WAN interface enslaved to a Linux bridge named `br-wan`, with the host IP, default route and DHCP on the bridge rather than the bare NIC (see [VPC Networking → Bridge Setup](https://docs.mulgadc.com/docs/vpc-networking#bridge-setup-physical-network-wiring))
+
+Check the bridge before continuing:
+
+```bash
+ip -br link show br-wan   # bridge exists and is UP
+ip route                  # default route's dev is br-wan
+```
+
+### Install and Run
+
+```bash
+mkdir -p ~/Development/mulga && cd ~/Development/mulga
+git clone https://github.com/mulgadc/spinifex.git
+sudo make -C spinifex quickinstall        # system packages, Go 1.27, AWS CLI v2
+export PATH=$PATH:/usr/local/go/bin
+
+cd spinifex
+./scripts/clone-deps.sh                   # sibling repos: viperblock, predastore, northstar, bluebottle
+./scripts/dev-install.sh                  # build, install, init a one-node cluster, start services
+
+AWS_PROFILE=spinifex aws ec2 describe-instance-types
+```
+
+A list of instance types means the cluster is up.
+
+`make preflight` also needs `shellcheck` and `golangci-lint`
+
+```bash
+sudo apt-get install -y shellcheck
+curl -sSfL https://golangci-lint.run/install.sh | sh -s -- -b "$(go env GOPATH)/bin" v2.14.0
+```
+
+The web console additionally needs Node.js 24 and `pnpm`.
+
+## Development Workflow
+
+| Command | Use it to |
+|---|---|
+| `make deploy` | Rebuild, install `spx`, and restart `spinifex.target` after a code change. |
+| `make reinstall` | Re-run `dev-install.sh` after changing systemd units, helper scripts, or logrotate config. |
+| `./scripts/reset-dev-env.sh` | Wipe all cluster state and reinstall from scratch, keeping your network topology. |
+| `make test` | Run unit tests (`make test-race` for the race detector). |
+| `make test-integration` | Run the real gateway router against embedded NATS JetStream. |
+| `make preflight` | Run the pre-commit gate: lint, `govulncheck`, coverage, and manifest and script checks. Must pass. |
+
+Follow the services with `journalctl -u 'spinifex-*' -f`.
+
+The web console lives in `spinifex/runtime/roles/spinifexui/frontend/` (`pnpm install`, `pnpm dev`, `pnpm lint`, `pnpm test`). `spx` embeds its checked-in `dist/`, so run `make build-ui` and commit the rebuilt `dist/` with your change.
+
+## Creating a Pull Request
+
+1. Fork [mulgadc/spinifex](https://github.com/mulgadc/spinifex) and clone your fork into the same parent directory as the sibling repositories, branching off `dev`:
+
+   ```bash
+   cd ~/Development/mulga
+   git clone git@github.com:YOUR_USERNAME/spinifex.git && cd spinifex
+   git remote add upstream git@github.com:mulgadc/spinifex.git
+   git fetch upstream && git checkout -b feat/my-feature upstream/dev
+   ```
+
+2. Make your change, then verify it:
+   - `make preflight` passes.
+   - `go mod tidy` leaves only intended changes in `go.mod` and `go.sum`, with none of the `clone-deps.sh` `replace` lines.
+   - Runtime changes are exercised on your dev cluster with `make deploy`.
+
+3. Commit using [Conventional Commits](https://www.conventionalcommits.org/) (`feat:`, `fix:`, `refactor:`, `docs:`, `chore:`), push, and open a pull request against `dev`, filling in the template.

-# Spinifex: An Open Source AWS-Compatible Stack for Bare-Metal, Edge, and On-Prem Deployments
+# Spinifex: the open, AWS-compatible cloud you run yourself
 
-Spinifex developed by [Mulga Defense Corporation](https://mulgadc.com) is an open source infrastructure platform that brings the core services of AWS—like EC2, VPC, EBS, and S3—to environments where running in the cloud isn't an option. Whether you're deploying to edge sites, private data-centers, or need to operate in low-connectivity or highly contested environments, Spinifex gives you AWS-style workflows on your own hardware.
+Spinifex, built by [Mulga](https://mulgadc.com), recreates the AWS services your software already uses on infrastructure you control. Move workloads off the hyperscalers, run AI at a fraction of the cost, or take the cloud to the edge, without rewriting a line.
 
-## What is Spinifex?
+- **Your AWS tooling, unchanged.** The AWS CLI, SDKs, and Terraform work as they are.
+- **Full control of the stack.** Your hardware, data, and keys, with no external control plane, running through disconnection.
+- **Open core under AGPL-3.0.** Auditable, yours to keep, with no lock-in.
 
-Spinifex replicates essential AWS primitives—virtual machines, block volumes, and object storage—using lightweight, self-contained components that are easy to deploy and integrate.
+You change *where* your software runs, not *what* it is.
 
-It's designed for developers and operators who need:
+## Try It Live
 
-- Cloud-like infrastructure without the cloud
-- Minimal dependencies, full control
-- Drop-in compatibility with tools like the AWS CLI, SDKs, and Terraform
-- A secure cloud environment you control and own the entire hardware, network and software stack
+Get a real Spinifex endpoint in under a minute, with no card and no install. The sandbox is yours for 72 hours, with access keys, the web console, and EC2, EBS, S3, VPC, IAM, EKS, and RDS ready to call. Point your existing AWS CLI or Terraform straight at it.
 
-You can run Spinifex on a few servers in a rack, a field site, or anywhere centralized cloud services aren't feasible.
+**[Create your sandbox →](https://mulgadc.com/signup)**
 
-## The Platform
+## Same Commands, Your Cloud
+
+```bash
+export AWS_PROFILE=spinifex
+aws ec2 describe-images
+aws ec2 run-instances --image-id ami-xxxxxxxx --instance-type t3.micro
+aws s3 mb s3://my-bucket
+```
+
+For Terraform, start from the [example workbooks](https://docs.mulgadc.com/docs/nginx-webserver).
+
+## Why Not LocalStack or Floci?
+
+[LocalStack](https://github.com/localstack/localstack) and [Floci](https://github.com/floci-io/floci) are emulators for local development and CI testing. An emulator returns a plausible response; Spinifex boots the machine. A call launches a real KVM guest, attaches a replicated Viperblock volume, or writes an erasure-coded object into Predastore, so Spinifex can run your production workloads on hardware you own. Test against an emulator, then run in production on Spinifex.
+
+## Services
+
+The platform serves **392 AWS API operations** across the services below. See exactly which ones in the [coverage report](https://docs.mulgadc.com/coverage).
+
+| Service | What it is | Built on | Status |
+| --- | --- | --- | --- |
+| **EC2** | Compute | QEMU/KVM, with spot instances and GPU passthrough | Available |
+| **EBS** | Block storage | [Viperblock](https://github.com/mulgadc/viperblock): replicated, with a WAL on local NVMe | Available |
+| **S3** | Object storage | [Predastore](https://github.com/mulgadc/predastore): Reed-Solomon erasure coding | Available |
+| **VPC** | Networking | OVN, with security groups | Available |
+| **IAM** | Identity & auth | SigV4 across every service | Available |
+| **ALB / NLB** | Load balancers | HAProxy (L7), nginx `stream` (L4), with ACM certificates | Available |
+| **EKS** | Kubernetes | k3s, with HA control planes and managed node groups | Available |
+| **ECR** | Container registry | Predastore, deduplicated per account | Available |
+| **ECS** | Container service | Spinifex instances | Available |
+| **RDS** | Databases | PostgreSQL and MariaDB, with automated backups | Available |
+| **Bedrock** | AI deployment | vLLM for text generation and Hugging Face TEI for embeddings and reranking | Q4 2026 |
+| **Lambda** | Serverless functions | | Q1 2027 |
+
+Roadmap services ship under the same AWS API surface, so code written for AWS today works the moment they land. [Track what's shipped in the release notes](https://github.com/mulgadc/spinifex/releases).
+
+## Deploy Anywhere
 
 <p align="center">
-  <img src=".github/assets/platform.svg" alt="The Mulga Platform — Hardware to Applications" width="900">
+  <img src=".github/assets/platform.svg" alt="The Spinifex stack: your apps and AWS tooling on top, the Spinifex AWS-compatible service layer, running on standard Linux on CPU and GPU hardware, deployable to Neocloud, on-premise, or the edge." width="900">
 </p>
 
-From commodity hardware up to unmodified AWS tooling, every layer is replaceable and yours to own.
+- **Neocloud:** lift and shift onto partner GPU capacity (H100 / H200 / B200). Change an endpoint, keep the software.
+- **On-premise:** a multi-node HA cluster in your own data centre, so the stack, the data, and the jurisdiction stay yours.
+- **Edge:** air-gapped sites, vehicles, vessels, factories, and clinics, with compute next to the data.
 
-## Core Components
+## Install
 
-### Spinifex (Compute Service – EC2 Alternative)
+Spinifex runs on Ubuntu 26.04 or Debian 13. The full guides are at [docs.mulgadc.com](https://docs.mulgadc.com).
 
-Spinifex is a minimal VM orchestration layer built on top of QEMU, exposing APIs similar to EC2. It manages lifecycle operations like start, stop, and terminate, using QEMU's QMP interface. Designed to be straightforward and scriptable, Spinifex lets you launch VMs using the AWS CLI, SDKs, or Terraform—without needing Kubernetes or heavyweight orchestrators. Keep in mind, you can also setup a Kubernetes environment using Spinifex with underlying instances.
+>*Prerequisite:* Spinifex requires a Linux bridge configured on the host for VM networking. See the [single-node install guide](https://docs.mulgadc.com/docs/install#prerequisites) for setup details.
 
-- EC2-like VM management on bare metal
-- Launches with cloud-init metadata support
-- Works with standard AWS tooling
-
-### Viperblock (Block Storage – EBS Alternative)
-
-[Viperblock](https://github.com/mulgadc/viperblock) is a high-performance, WAL-backed block storage service that replicates volumes across multiple nodes. It's built for reliability and speed, with support for snapshots, recovery, and direct connection to QEMU instances using NBD or virtio-blk.
-
-- Fast, durable virtual disks
-- Replication for resilience
-- Exposed over NBD or embedded in VMs
-- Supports high performance WAL logs using local NVMe drives to reduce IO traffic to S3.
-- In memory read/write block cache for blazing performance.
-
-### Predastore (Object Storage – S3-Compatible)
-
-[Predastore](https://github.com/mulgadc/predastore) is a fully S3-compatible object storage system. It supports the AWS S3 API, including Signature V4 authentication, multipart uploads, and Terraform provisioning. Data is chunked and distributed across nodes using Reed-Solomon erasure coding, making it fault-tolerant and ideal for large-scale or low-bandwidth scenarios.
-
-- S3-compatible API and auth
-- Multipart uploads, streaming reads/writes
-- Data redundancy with Reed-Solomon encoding
-
-## Architecture at a Glance
-
-<p align="center">
-  <img src=".github/assets/architecture.svg" alt="Spinifex message-driven architecture — AWS Gateway, NATS bus, service daemons" width="900">
-</p>
-
-Every AWS API call is authenticated at the gateway, published to a NATS subject, and answered by whichever daemon claims it. Daemons are stateless — scale horizontally by starting more. No etcd, no Kubernetes, no external control plane. Deep dive: **[`docs/DESIGN.md`](docs/DESIGN.md)**.
-
-## Key Features
-
-AWS-Compatible Interfaces – Provision infrastructure with awscli, Terraform, or SDKs you already use.
-
-- Designed for Control – Run on your own terms, whether that's in a datacenter, remote site, or sensitive environment.
-- Minimal Dependencies – Each service is standalone and avoids complex orchestration layers.
-- Works Offline – No reliance on centralized cloud services or external networks.
-- Open Source – Licensed under AGPL 3.0. Fork it, extend it, or deploy it as-is.
-
-## Installation
-
-Installation requires an Ubuntu / Debian system. See the detailed documentation at [docs.mulgadc.com](https://docs.mulgadc.com) for maintaining and installing Spinifex.
-
-### Bare Metal ISO
-
-The recommended installation is a [bootable x86 installer](https://iso.mulgadc.com/spinifex.iso) for bare-metal hardware.
+**Bare metal (recommended):** download the [bootable x86 installer](https://iso.mulgadc.com/spinifex.iso) and follow the [USB install guide](https://docs.mulgadc.com/docs/install-usb).
 
 ```bash
 curl -fLO https://iso.mulgadc.com/spinifex.iso
 ```
 
-Follow the [USB install guide](https://docs.mulgadc.com/docs/install-usb) to write the ISO to USB and install on your hardware. The install guide walks through the full process.
-
-
-### Single Node Install
-
-The installation is straightforward to set up and running on a single node for testing purposes. Debian 13 is currently supported, additional Linux distributions are on the immediate roadmap.
-
->*Prerequisite:* Linux bridge for networking.
-
-Spinifex requires a Linux bridge configured on the host for VM networking. See the [single-node install guide](https://docs.mulgadc.com/docs/install#prerequisites) prerequisites for setup details.
+**Single node:**
 
 ```bash
 curl -fsSL https://install.mulgadc.com | bash
-
 sudo /usr/local/share/spinifex/setup-ovn.sh --management
-
 sudo spx admin init --node node1 --nodes 1
-
 sudo systemctl start spinifex.target
-
 export AWS_PROFILE=spinifex
-
 aws ec2 describe-instance-types
 ```
 
-### Development Setup
+**From source:** see the [Source Install](https://docs.mulgadc.com/docs/install-source) guide.
 
-For a complete development environment see the [Source Install](https://docs.mulgadc.com/docs/install-source) documentation
-
-### Component Repositories
-
-Spinifex coordinates these independent components:
-
-- **[Predastore](https://github.com/mulgadc/predastore)** - S3-compatible object storage
-- **[Viperblock](https://github.com/mulgadc/viperblock)** - EBS-compatible block storage
-
-Each component can be developed independently. See component-specific documentation for focused development guides.
-
-## Spinifex UI
-
-Spinifex ships with a built-in web console — an optional alternative to the AWS CLI, SDKs, and Terraform. If you're familiar with the AWS Management Console, the Spinifex UI fills the same role: a browser-based view of your instances, volumes, buckets, VPCs, and IAM resources, without leaving your own network.
+## Web Console
 
 <p align="center">
-  <img src=".github/assets/spinifex-ui.jpg" alt="Spinifex web console — dashboard view" width="900">
+  <img src=".github/assets/spinifex-ui.jpg" alt="Spinifex web console dashboard" width="900">
 </p>
 
-The console is served by each node on port `3000` over TLS, and becomes available as soon as `spinifex.target` is up:
+Spinifex ships with a built-in web console for your instances, volumes, buckets, networks, and IAM. See [Launching the Web UI](https://docs.mulgadc.com/docs/setting-up-your-cluster#7-launching-the-web-ui).
 
-```bash
-open https://YOUR_NODE_IP:3000
-```
+## Architecture
 
-- **Same API, different surface.** Every action in the UI is the same AWS SigV4 call the CLI makes — so RBAC, audit trails, and IAM policies apply uniformly.
-- **Single sign-on against your AWS credentials.** Log in with the access keys from `~/.aws/credentials` on the node where Spinifex is installed — no separate user database.
-- **Self-hosted, works offline.** The UI is embedded in the Spinifex binary and served from the node itself. No external CDN, no analytics calls, no cloud dependency.
+<p align="center">
+  <img src=".github/assets/architecture.svg" alt="Spinifex message-driven architecture: standard AWS clients call the AWS Gateway over HTTPS with SigV4, which publishes to a NATS bus answered by stateless ec2/ebs/s3/vpc/iam daemons over local backends." width="900">
+</p>
 
-For the full walkthrough — first-time TLS certificate trust, login, and feature tour — see [**Launching the Web UI**](https://docs.mulgadc.com/docs/setting-up-your-cluster#7-launching-the-web-ui) in the cluster setup guide.
+Every AWS API call is authenticated at the gateway, published to a NATS subject, and answered by whichever daemon claims it. Daemons are stateless, so you scale horizontally by starting more. Deep dive: **[`docs/DESIGN.md`](docs/DESIGN.md)**.
 
-## Development Philosophy
+## How We Build Spinifex
 
-### Built by Engineers, For Engineers
+Spinifex is built by infrastructure engineers with deep AWS experience, including former AWS team members, drawing on decades of combined work across AWS, enterprise infrastructure, and edge computing. Engineers architect and implement it, with **Claude Code** accelerating parts of the work.
 
-Spinifex is developed by experienced infrastructure engineers with deep AWS expertise, including former AWS team members who understand the intricacies of building production-grade cloud services. Our team brings decades of combined experience from AWS, enterprise infrastructure, and edge computing environments.
-
-**Real-World Experience:**
-
-- Production AWS service development and operations
-- Large-scale infrastructure deployment and management
-- Edge computing and resource-constrained environments
-- Enterprise security and compliance requirements
-
-### AI-Assisted Development
-
-While Spinifex is architected and implemented by experienced engineers, we leverage **Claude Code** (Anthropic's AI coding assistant) to accelerate certain development tasks. This approach combines human expertise with AI efficiency:
-
-**How We Use Claude Code:**
-
-- **Code Generation**: Boilerplate AWS API structures and handlers
-- **Documentation**: Comprehensive development guides and API documentation
-- **Testing**: Test case generation and validation scenarios
-- **Refactoring**: Large-scale code restructuring and optimization
-
-**What Remains Human-Driven:**
-
-- **Architecture Decisions**: Core system design and scalability choices
-- **Security Implementation**: Authentication, encryption, and threat modeling
-- **Performance Optimization**: Real-world performance tuning and benchmarking
-- **Production Operations**: Deployment strategies and operational procedures
-
-This hybrid approach ensures Spinifex benefits from both proven engineering expertise and modern development acceleration, while maintaining the quality and reliability standards required for production infrastructure.

+# Security Policy
+
+## Reporting a Vulnerability
+
+Please do not open a public issue for a security vulnerability.
+
+Report it privately, either way works:
+
+- [Open a private security advisory](https://github.com/mulgadc/spinifex/security/advisories/new) on this repository.
+- Email <security@mulgadc.com>.
+
+Please include enough for us to reproduce it: the version or commit, the configuration involved, and the steps that trigger it. If you have a proof of concept, include that too.
+
+## What Happens Next
+
+We aim to acknowledge a report within three business days. We will confirm whether we can reproduce it, agree a fix and a disclosure timeline with you, and credit you in the advisory unless you would rather we did not.
+
+## Scope
+
+Spinifex is one part of the [Mulga](https://mulgadc.com) stack. If a vulnerability spans more than one component, report it once against whichever repository you found it in and we will handle the rest.
+
+## Supported Versions
+
+Fixes land on the latest release and on `main`. Older releases are not patched.

 # JetStream liveness watchdog for spinifex-nats.
 #
-# NATS can disable JetStream at runtime (e.g. a filesystem permission error while
-# flushing stream state) and keep the process alive serving KV as read-only. That
-# is not a process failure, so Restart=on-failure never fires and KV-backed
-# services (awsgw IAM bucket init, etc.) stall until NATS is restarted by hand.
+# NATS can stop accepting JetStream writes at runtime while the process stays
+# alive and keeps serving reads. That is not a process failure, so
+# Restart=on-failure never fires and KV-backed services (awsgw IAM bucket init,
+# etc.) stall until NATS is restarted by hand.
 #
-# This probes the NATS monitoring endpoint's JS health and restarts the service
-# only when JetStream is sustainedly unhealthy while the service is running. The
-# multi-sample window avoids restarting during transient startup/quorum 503s.
+# Two distinct latches produce that symptom, and they need different probes:
+#
+#   1. Server-wide. handleOutOfSpace calls ShutdownJetStream and sets an
+#      internal disabled flag that only a restart clears. healthz reports it.
+#   2. Per message block. filestore records a write error on the block and
+#      returns it on every later write; nothing clears it short of a restart.
+#      healthz does NOT report it, because the server-wide state is untouched —
+#      only an actual write observes it.
+#
+# So a health check alone misses case 2 entirely. Both probes run here, and a
+# sustained failure of either restarts the service. The multi-sample window
+# avoids restarting during transient startup/quorum 503s.
+#
+# Three more guards sit around that decision, because "restart when the
+# probes fail" is not safe on its own:
+#
+#   - Age gate: spinifex-nats.service is Type=simple, so it reports active the
+#     instant the process forks, long before JetStream finishes replaying its
+#     state. Acting before a recovery budget has elapsed restarts a server
+#     that is still coming up, not one that has failed.
+#   - Cooldown: a restart that did not fix things must not be retried by the
+#     very next run, seconds later.
+#   - Escalation: a restart that has not fixed things after several attempts
+#     is not going to fix it on the next one either, and an unrunnable spx
+#     must never be read as proof of a JetStream failure at all.
