fix(awserrors): attach Retry-After without duplicating the error text (#1244)

Joining a coded error with RetryAfter rendered the bare code on a second
line, so logged and stored reasons read "...: ServiceUnavailable
ServiceUnavailable". Add WithRetryAfter, which wraps the error and keeps
its text while ResolveRetryAfter and ResolveErrorDetail still resolve the
hint and the code. Use it for the seal-capability refusal and the
incomplete DescribeInstances and DescribeInstanceTypes fan-out errors.

+# 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: the open, AWS-compatible cloud you run yourself
 
-Spinifex, built by [Mulga](https://mulgadc.com), recreates the AWS services your software already uses (EC2, EBS, S3, VPC, IAM) 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. The exact build you ship to AWS, Spinifex serves on your own hardware: same APIs, same Terraform, same SDKs.
+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?
-
-Spinifex is an open-source infrastructure platform that recreates the AWS service surface (EC2, EBS, S3, VPC, IAM) on bare-metal, edge, and on-premises environments. Run cloud-native software without a hyperscaler.
-
-Most AWS alternatives wrap an API and call it a cloud. We rebuilt the engineering underneath: distributed object storage with erasure coding, block storage built to survive failure, and compute on bare metal. That depth is the reason your software runs unchanged, instead of rewritten.
-
-It's built for teams that need:
-
-- The AWS tooling they already use (AWS CLI, SDKs, Terraform), with nothing to rewrite
-- Full control of the stack: your hardware, your network, your data, your keys
-- A cloud that keeps running offline, through disconnection, with no external control plane
-- An open core (AGPL-3.0), auditable and yours to keep, with no lock-in
+- **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.
 
 You change *where* your software runs, not *what* it is.
 
-## The Platform
+## Try It Live
+
+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.
+
+**[Create your sandbox →](https://mulgadc.com/signup)**
+
+## 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).

+
+## Deploy Anywhere
 
 <p align="center">
   <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.
 
-## Three Ways To Deploy
+## Install
 
-One AWS-compatible surface, three deployment shapes. Pick the one that matches your reality; the platform on top is the same.
+Spinifex runs on Ubuntu 26.04 or Debian 13. The full guides are at [docs.mulgadc.com](https://docs.mulgadc.com).
 
-### Neocloud
+>*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.
 
-Lift and shift onto a partner Neocloud. Move workloads off the hyperscalers and onto our Neocloud partner ecosystem without rewriting them. GPU capacity (H100 / H200 / B200), cheaper, available now. Change an endpoint, keep the software.
-
-### On-premise
-
-Bring your own hardware and host Spinifex in your own data centre. A real multi-node HA cluster integrated with your storage and networking, with full control of stack, data, and jurisdiction. A predictable bill, no egress surprises, an auditable open-source core.
-
-### Edge
-
-Cloud where the cloud can't reach. Air-gapped sites, vehicles, vessels, factories, and clinics. Compute next to the data, running through disconnection, on hardware you own. The same AWS APIs your software already uses.
-
-## AWS Compatibility
-
-Speak the AWS API surface, natively. The AWS SDKs, AWS CLI, and Terraform: everything you deploy on AWS deploys on Spinifex unchanged. At the edge, on-premise, or on a partner Neocloud.

-
-## Core Components
-
-### Spinifex (Compute Service – EC2 Alternative)
-
-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.
-
-- 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
-
-### Northstar (Authoritative DNS)
-
-[Northstar](https://github.com/mulgadc/northstar) is a lightweight authoritative DNS server that handles both internal service discovery and public-facing DNS for a Spinifex cluster. Zones are human-readable TOML files, served from the local filesystem or synced from Predastore, keeping DNS configuration in the same object storage as the rest of your infrastructure.
-
-- Authoritative DNS over UDP, TCP, and DNS-over-TLS
-- Service discovery for cluster components via SRV records
-- Zone files stored locally or in S3-compatible storage
-
-## Architecture at a Glance
-
-<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>
-
-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. Just systemd units, a NATS cluster, and your hardware. Deep dive: **[`docs/DESIGN.md`](docs/DESIGN.md)**.
-
-## Key Features
-
-- **AWS-compatible APIs.** Use the AWS CLI, SDKs, and Terraform you already know. Repoint your endpoint and ship; nothing to rewrite.
-- **Zero cloud dependency.** Runs entirely on your hardware. No phone-home, no control plane, no external authority. Works fully offline.
-- **Bare-metal compute.** QEMU-based with direct hardware access. No hypervisor tax, no abstraction overhead.
-- **Built-in storage.** Block and object storage included: NVMe caching, Reed-Solomon erasure coding, and replication out of the box.
-- **Edge-first architecture.** Designed for disconnected, contested, and resource-constrained environments from day one.
-- **Open core, no lock-in.** AGPL-3.0 with a commercial option. Inspect it, modify it, deploy it. The platform is yours to keep.
-
-## Installation
-
-Installation requires an Ubuntu 26.04 or Debian 13 system. See the detailed documentation at [docs.mulgadc.com](https://docs.mulgadc.com) for 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.
-
-### Single Node Install
-
->*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.
+**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
-- **[Northstar](https://github.com/mulgadc/northstar)** - Authoritative DNS server
-
-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).
 
-- **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.
+## Architecture
 
-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.
+<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>
 
-## Development Philosophy
+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)**.
 
-### Built by Engineers, For Engineers
+## How We Build Spinifex
 
-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.
+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.
 
-**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.
