 # 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.
-
-Built for teams that need:
-
- The AWS tooling you 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).
+
+| Service | What it is | Built on | Status |
+| --- | --- | --- | --- |

+| **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 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

-The same AWS-compatible platform runs in three shapes. Pick the one that matches your hardware.
+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 without rewriting workloads. GPU capacity (H100 / H200 / B200), cheaper, available now. Change an endpoint, keep the software.
-
-### On-premise
-
-Host Spinifex on your own hardware in your own data centre. You get a multi-node HA cluster integrated with your storage and networking, so the stack, the data, and the jurisdiction stay yours.
-
-### 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
-
-Spinifex speaks the AWS API surface. The AWS SDKs, AWS CLI, and Terraform all work unchanged, whether you deploy at the edge, on-premise, or on a partner Neocloud.

-## Core Components
-
-### Spinifex (Compute and Platform Services – EC2, EKS, ECS, RDS)
-
-Spinifex is a minimal VM orchestration layer built on top of QEMU, exposing an EC2 compatible API. It manages lifecycle operations like start, stop, and terminate through QEMU's QMP interface. Designed to be straightforward and scriptable, Spinifex lets you launch VMs with the AWS CLI, SDKs, or Terraform, without Kubernetes or a heavyweight orchestrator.
-
-The managed services build on that same instance layer. An EKS node group, an ECS container instance, and an RDS database are Spinifex VMs on your own hardware, each driven through its own AWS API.
-
- **EC2** – VM lifecycle on bare metal, cloud-init and IMDS metadata, key pairs, tags, spot instances, capacity reservations, and GPU passthrough
- **EKS** – Managed Kubernetes on k3s, with HA control planes, managed node groups, cluster add-ons, an OIDC provider, and IAM access entries
- **ECS** – Task and service scheduling across container instances, with awsvpc ENIs, capacity providers, rolling deployments, and GPU-aware placement
- **ECR** – Private container registry backed by Predastore, with content-addressed blobs deduplicated per account and lifecycle policies
- **RDS** – Managed PostgreSQL and MariaDB, with parameter groups, automated backups, and DNS endpoints served by Northstar
- **ALB / NLB** – Layer 7 load balancing on HAProxy and layer 4 on nginx `stream`, with health checks and ACM-issued listener certificates
- **VPC and IAM** – OVN-backed networking and security groups, with roles, policies, and SigV4 auth applied across every service
-
-### 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
- High performance WAL logs on local NVMe drives, reducing IO traffic to S3
- In-memory read/write block cache
-
-### 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. Predastore chunks data and distributes it across nodes using Reed-Solomon erasure coding, so it survives node loss and suits large-scale or low-bandwidth sites.
-
- 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)**.
-
-## Self-hosted 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.

-## Spinifex UI
-
-Spinifex ships with a built-in web console, an optional alternative to the AWS CLI, SDKs, and Terraform. If you know 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" width="900">
 </p>

-Each node serves the console on port `3000` over TLS, and it comes up with `spinifex.target`:
+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.** The UI issues the same AWS SigV4 calls the CLI does, so RBAC, audit trails, and IAM policies apply the same way.
- **Single sign-on against your AWS credentials.** Log in with the access keys from `~/.aws/credentials` on the node where Spinifex is installed. There is no separate user database.
- **Self-hosted, works offline.** The Spinifex binary embeds the UI and each node serves it directly, with no external CDN or analytics calls.
+## Architecture

-For the full walkthrough, covering first-time TLS certificate trust, login, and a 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.

+# Cluster v1 contracts

+This package owns the versioned cluster control-plane wire contracts. It is
+not an AWS tenant-facing API: it lets platform consumers identify responding
+daemon nodes and inspect their health.
+
+`NodesDiscoverSubject` retains the deployed `spinifex.nodes.discover` route.
+`NodeDiscoverResponse.Node` is the node identifier used for responder-set
+coverage. Do not change either incompatibly in this package; add a new version
+when a wire change is required.
+
+`NodeHealthSubject` retains the deployed per-node NATS route, while
+`NodeHealthResponse` is also the daemon HTTPS `/health` representation. Do not
+change their subject or JSON shape incompatibly in this package; add a new
+version when a wire change is required.
+
+`NodeVMsSubject` retains the deployed `spinifex.node.vms` fan-out route.
+`NodeVMsResponse` is the VM inventory reply used by the SPX operator CLI and
+by EKS host lookup. It is distinct from node status and capacity reporting:
+do not add scheduling or physical-GPU inventory merely because those callers
+also inspect nodes. Do not change its subject or JSON shape incompatibly; add
+a new version when a wire change is required.
+
+`NodeStatusSubject` retains the deployed `spinifex.node.status` fan-out route.
+`NodeStatusResponse` carries daemon-reported status, schedulable capacity and
+physical-GPU inventory for the SPX operator CLI and EC2/EKS placement callers.
+It is an observation contract, not the owner of capacity, scheduling or GPU
+allocation policy. Do not change its subject or JSON shape incompatibly; add

+# EC2 instance-command contract, version 1
+
+This package owns the cross-process contract used to direct a command to the
+node that owns a running EC2 instance. It is not an in-process service
+interface or the owner of instance state.
+
+## Route and purpose
+
+The subject is `ec2.cmd.<instance-id>`. It is request/reply, and the daemon
+that hosts that instance's QEMU process is the only subscriber. This route
+exists because lifecycle operations such as start, stop, terminate, volume
+attach/detach and ENI attach/detach must reach that one process; sending them
+through the normal daemon queue group could select a different node.
+
+`InstanceCommandSubject` constructs a targeted subject. The corresponding
+subscription and permission pattern is `ec2.cmd.*`: the `*` deliberately
+matches exactly one final instance-ID token, not an arbitrary descendant.
+
+## Compatibility boundary
+
+`EC2InstanceCommand`, its nested data objects, their JSON field names and the
+subject shape are wire compatibility. Callers and receivers must use this
+package rather than rebuild those details. `commands_test.go` preserves the
+version-1 JSON shape and subject form.
+
+This package owns shared command payloads and the drain-volume response. It
+does not define every action's reply body, authorize the request, store EC2
+state or implement NATS transport. Those remain responsibilities of the EC2
+domain and its runtime composition.
+
+Any incompatible subject or payload change requires an explicit versioned
+contract or an approved compatibility plan; it is not a package refactor.
+
+## Default VPC request
+
+`EnsureDefaultVpcSubject` (`ec2.EnsureDefaultVpc`) is the request/reply route on which the gateway's account creation asks a daemon in the `spinifex-workers` queue group to build the account's default VPC.
+Only the subject is owned here today.
+The request (`account_id`) and reply (`vpc_id`, `error`) bodies are still declared as anonymous structs on each side; moving them into this package is a contract change that needs its own characterization first.
+
+## Platform inventory
+
+`PlatformInventorySubject` (`ec2.v1.PlatformInventory`) is a request/reply route on which a daemon in the `spinifex-workers` queue group reports one account's key pairs, placement groups, launch templates and their `ec2-tags` entries from the EC2 owner stores.
+EC2 owns it: `domains/ec2/accountinventory` produces the reply and the daemon serves it; the only consumer today is `accountteardown`, which binds an adapter but does not call it.
+
+The request names the account in its body (`account_id`, a 12-digit ID) and may carry an opaque `correlation_ref` that is echoed for logs.
+The daemon ignores `X-Account-ID` for this subject.
+Neither field grants anything: the subject is read-only, writes to no store, and its reply is never authority to delete.
+
+The reply has one `kinds` entry per kind (`key-pair`, `placement-group`, `launch-template`, `tag-index`) with a status and scan start and end times.
+The times are zero when no owner scan ran: a consumer-synthesised `scan-incomplete` report for no responder, a timeout or a transport failure carries zero timestamps and must not be read as a scan.
+`observed-clean-at-scan-time` means every store for that kind was read completely and held nothing at scan time; writers are not fenced, so it is a snapshot and never evidence of absence.
+`items` carry only a resource ID, kind and disposition (`live`, `dependency-held`, or tag-index `residue`), which are the identities the per-kind Describe subjects already return.
+A `dependency-held` placement group does not name its member instances, which may be stale and are not exposed by the existing subjects.
+Records no existing subject exposes (public-key objects without metadata, launch-template version bodies and name-index entries without a header, and every unreadable record) appear only as aggregate `counts` per kind, disposition and class.
+The reply never carries an object key, raw KV key, key or template name, tag key or value, public-key bytes, launch-template data, user data, record body or store error text; `incomplete_reasons` are fixed categories.
+
+### Compatibility boundary
+
+The subject name carries the contract major; `platform_inventory_test.go` preserves the version-1 JSON shape and wire vocabulary.
+Producer and consumer are in the coordinated Spinifex release, so the window is N and N-1.
+A daemon that predates the subject has no subscription, so the request gets no responder; the consumer treats no responder, a timeout, an error reply, an undecodable reply, a reply for another account, and a missing, repeated or unknown-status kind as `scan-incomplete`, never clean.
+An incompatible change to the subject, fields or vocabulary needs a new major.

+# ECS agent/scheduler bus contract, version 1
+
+This package owns the deployed wire vocabulary for the `ecs.bus.*`
+scheduler-to-agent boundary: subjects, payload JSON and the Layer-2 message
+types. It is a characterization of what is deployed today, not a redesign; it
+does not move the scheduler, the agent, or perform any NATS I/O itself.
+
+## Route table
+
+| Subject | Payload | Reply | Delivery | Queue group | Producer | Consumer |
+|---|---|---|---|---|---|---|
+| `ecs.bus.<account>.<cluster>.instance-register.<instanceId>` | `RegisterInstance` | none | fire-and-forget | none | none today | `spinifex_daemon` leader, `handlers/ecs/scheduler.go` `onRegister` |
+| `ecs.bus.<account>.<cluster>.instance-heartbeat.<instanceId>` | `Heartbeat` | none | fire-and-forget | none | none today | `spinifex_daemon` leader, `handlers/ecs/scheduler.go` `onHeartbeat` |
+| `ecs.bus.<account>.<cluster>.assign.<instanceId>` | `Assign` | none | fire-and-forget | none | none today | none today |
+| `ecs.bus.<account>.<cluster>.task-state.<taskId>` | `TaskState` | none | fire-and-forget | none | none today | `spinifex_daemon` leader, `handlers/ecs/scheduler.go` `onTaskState` |
+| `ecs.bus.<account>.<cluster>.service-reconcile` | none | none | fire-and-forget | none | `spinifex_daemon`, `handlers/ecs/instances.go` `SubmitTaskStateChange` | `spinifex_daemon` leader, `handlers/ecs/scheduler.go` `onReconcileWake` |
+
+The agent today registers, heartbeats and reports task state through the AWS
+gateway's `RegisterContainerInstance`, `PollAssignments` and
+`SubmitTaskStateChange` NATS actions instead of publishing on this bus; those
+actions are a separate, pre-existing subject family and carry some of the
+same message types (`Assign`, `TaskState`, `StopDirective`) as their wire
+body. Four of the five subject builders above, every route except
+`service-reconcile`, therefore have no current publisher. The scheduler still
+subscribes to all four wildcard patterns; only its election leader holds the
+subscriptions, which is why no queue group is needed. `service-reconcile` is
+the one route with a live producer and consumer: the worker that recorded a
+task-state change is rarely the leader, so it publishes a cross-node wake the
+leader's own subscription picks up.
+
+`StopDirective`, `ContainerStatus`, `InstanceCapacity`, `PortMapping`,
+`AssignContainer` and `SystemControl` are nested payload types carried inside
+`Assign` and `TaskState`; they travel on the same routes as their parent type
+and are not separately addressed.
+
+## Ownership
+
+The ECS domain owns the meaning of every subject and type in this package.
+The ecs-agent binary baked into the ECS node AMI is a deployed consumer: it
+decodes `Assign` and `StopDirective` and encodes `TaskState`, all carried
+today by the AWS-gateway actions that reuse these types.
+It does not encode `Heartbeat` or `RegisterInstance`.
+
+## Compatibility rules
+
+This is the deployed v1 contract. Changes follow N/N-1: a subject, JSON field
+name, JSON field type, or message semantics must not be renamed, retyped, or
+reinterpreted to mean something else. The AMI-baked agent cannot be upgraded
+in lockstep with the daemon, so it must keep decoding the shapes it already
+knows; `messages_test.go` pins the older agent's `AssignContainer` shape
+against the current one for exactly this reason. A breaking change needs a
+new, explicitly versioned successor package, not an edit here.
+
+## What this package does not do
+
+It does not move the scheduler, the agent, or any subscriber out of its
+current package, and it changes no ECS lifecycle behaviour: every subject
+string, JSON field and message type here is identical to the one the
+`handlers/ecs/bus` package declared before this move.

+# EKS v1 contracts
+
+This package owns the deployed EKS add-on contract between the control-plane guest (the on-VM addon-sync agent, `eks-gateway-fetch` and `eks-gateway-publish`) and the host (the AWS gateway and the cluster reconciler). It is not an AWS tenant-facing API.
+
+## Delivery report
+
+`AddonStatusSubject` retains the deployed `eks.addon.<account>.<cluster>.status` route. The guest's `mulga-eks-addon-sync.sh` builds an `AddonStatusReport` with `printf`, so it always sends `message` (possibly empty); the gateway relays the payload verbatim on the `addon` channel of `internal-publish`. `AddonDeliveryPhase` is the closed set `applied`, `ready`, `failed`.
+
+## Staged manifests
+
+`InternalAddonsResponse` is the body of `GET /clusters/{name}/internal-addons/{account}`. The gateway renders it with the AWS SDK REST-JSON marshaller (`jsonutil.BuildJSON`), which ignores `json` tags, so the deployed body uses Go field names and always includes empty strings, for example `{"Addons":[{"AddonName":"x","AddonVersion":"1","ServiceAccountRoleArn":"","ConfigurationValues":""}]}`. The guest decodes it with `encoding/json`, which matches keys case-insensitively, then emits it as tab-separated lines for the shell agent.
+
+The `json` tags on `StagedAddonManifest` are the host-internal NATS form used between the gateway and the daemon (`eks.ListStagedAddonManifests`). They do not describe the guest-facing body.
+
+## Compatibility boundary
+
+The subject, phase values, both JSON forms and Go field names are wire compatibility; `addon_status_test.go` and `addon_manifest_test.go` pin them with literal bytes. A generation-aware or otherwise incompatible delivery protocol needs a successor version; it is not a v1 change.

+# Network realisation contract, version 1
+
+This package owns the deployed wire vocabulary for the `vpc.*`
+control-plane-to-network-realisation boundary: subjects, payload JSON, the
+`{success,error}` acknowledgement envelope, delivery mode and the
+`vpcd-workers` queue group. It does not move `vpcd`, perform any NATS I/O, or
+change any lifecycle or reliability semantics. It is a characterization of
+what is deployed today, split one route family per file, not a redesign.
+
+## Ownership
+
+Network owns the meaning and wire contract of every route below, because it
+owns OVN and host realisation. EC2 and the other managed-service domains own
+their own AWS-visible state transitions and decide when, and whether, to
+issue a projection onto one of these subjects; this package does not grant
+them authority over a route's semantics, only a stable shape to publish
+against.
+
+## Route table
+
+| Subject | Payload | Reply | Delivery | Queue group |
+|---|---|---|---|---|
+| `vpc.create` | `VPCEvent` | none | fire-and-forget | `vpcd-workers` |
+| `vpc.delete` | `VPCEvent` | none | fire-and-forget | `vpcd-workers` |
+| `vpc.create-subnet` | `SubnetEvent` | none | fire-and-forget | `vpcd-workers` |
+| `vpc.delete-subnet` | `SubnetEvent` | none | fire-and-forget | `vpcd-workers` |
+| `vpc.create-port` | `PortEvent` | `AckEnvelope` | request/reply, 5s | `vpcd-workers` |
+| `vpc.delete-port` | `PortEvent` | `AckEnvelope` | request/reply, 5s; caller treats failure as non-fatal | `vpcd-workers` |
+| `vpc.update-port-sgs` | `PortSecurityGroupsUpdateEvent` | `AckEnvelope` | request/reply, 5s | `vpcd-workers` |
+| `vpc.igw-attach` | `InternetGatewayEvent` | none | fire-and-forget, non-fatal | `vpcd-workers` |
+| `vpc.igw-detach` | `InternetGatewayEvent` | none | fire-and-forget, non-fatal | `vpcd-workers` |
+| `vpc.add-nat` | `NATEvent` | `AckEnvelope` | request/reply, 45s (OVN flows barrier); some callers fire-and-forget | `vpcd-workers` |
+| `vpc.delete-nat` | `NATEvent` | `AckEnvelope` | request/reply, 15s, retried on `ErrNoResponders` (3 attempts, 500ms apart) | `vpcd-workers` |
+| `vpc.add-nat-gateway` | `NATGatewayEvent` | none | fire-and-forget | `vpcd-workers` |
+| `vpc.delete-nat-gateway` | `NATGatewayEvent` | none | fire-and-forget | `vpcd-workers` |
+| `vpc.add-igw-route` | `IGWRouteEvent` | none | fire-and-forget | `vpcd-workers` |
+| `vpc.delete-igw-route` | `IGWRouteEvent` | none | fire-and-forget | `vpcd-workers` |
+| `vpc.gate-subnet-egress` | `SubnetEgressGateEvent` | none | fire-and-forget | `vpcd-workers` |
+| `vpc.ungate-subnet-egress` | `SubnetEgressUngateEvent` | none | fire-and-forget | `vpcd-workers` |
+| `vpc.add-system-egress` | `SystemEgressEvent` | none | fire-and-forget | `vpcd-workers` |
+| `vpc.delete-system-egress` | `SystemEgressEvent` | none | fire-and-forget | `vpcd-workers` |
+| `vpc.create-sg` | `SecurityGroupEvent` | `AckEnvelope` | request/reply, 5s | `vpcd-workers` |
+| `vpc.delete-sg` | `SecurityGroupEvent` | `AckEnvelope` | request/reply, 5s, idempotent | `vpcd-workers` |
+| `vpc.update-sg` | `SecurityGroupEvent` | `AckEnvelope` | request/reply, 5s | `vpcd-workers` |
+
+Producer for every route above is the daemon (`spinifex-daemon`), through the
+typed client in `domains/network/projection`; `vpc.add-system-egress` has no
+current producer.
+Consumer for every route is `vpcd`, by way of `domains/network/subscribers`.
+This package is the sole declared owner of every subject and type above,
+including `vpc.igw-attach`/`vpc.igw-detach`, which were previously also
+declared in `contracts/ec2/v1`; that duplicate has been removed.
+
+## Compatibility rules
+
+This is the deployed v1 contract. Changes follow N/N-1: a subject, JSON field
+name, JSON field type, or the ack envelope shape must not be renamed,
+retyped, or reinterpreted to mean something else. A breaking change needs a
+new, explicitly versioned successor package, not an edit here. Every subject
+and golden JSON literal in this package is pinned by an external `_test`
+package; a failing pin means the change broke compatibility, not that the
+test is stale.
+
+## What this package does not do
+
+It does not move `vpcd` or any subscriber out of its current package. It does
+not change any route's delivery mode, timeout, retry budget, queue group, or
+the NAT add barrier.
