feat(ui): console feedback v1 and the admin Nodes view (#1454 )

* feat(ui): console feedback round: state tones, inline tags, filter bar and form fixes Settled states go green and transitions yellow with a spinner, status text is lowercase, tags are edited inline row by row, every list filters through one filter bar, long cells truncate with a tooltip and times are relative. EC2 launch takes a Name and offers ICMP echo, and leaves Placement Group out when no group is available. RDS create is reordered with engine tiles and window pickers. Route 53 records get bulk delete, a TTL select, value labels that follow the type, and NS. Tooltips use the popover tokens, and the console is sized over a 110% root. * feat(ui): size RDS instance classes and give each record value its own input An RDS class is a db.-prefixed EC2 type, so the class picker shows its vCPUs and memory in every option and under the field, as the EC2 launch form does, on create, modify and restore. A Route 53 record's values were one textarea, which let a line break into a value. Each value is now a single-line input with Add value; Enter starts the next one, a pasted list splits into rows, and CNAME takes exactly one. * fix(ui): open a DNS record for editing from the keyboard * feat: admin node inventory, topology, live host metrics and network test Each node collects its hardware facts as root at daemon start (dmidecode, ethtool, networkctl LLDP where available) into /etc/spinifex/node-facts, and the daemon serves them with its plane wiring over NATS. New admin-only actions, refused for every account but the system admin account regardless of policy: - GetNodeFacts: hardware, NICs, LLDP neighbours and planes per node - GetNodeMetrics: live CPU, memory and per-plane traffic for one node - StartNetworkTest / DescribeNetworkTests: iperf2 between nodes over a chosen plane, both directions, one test cluster-wide at a time, recorded in KV and converged asynchronously The iperf listener runs only for the duration of a run, without capabilities, on TCP 5001, which the peers firewall rule now allows. A run refuses any target outside the node's own plane subnet. The console gains a node panel (hardware, network, metrics, network test with a dial scaled to the port's line rate) and a topology view built with @xyflow/react. setup.sh installs dmidecode and iperf. * test: cover the node insight handlers and the facts file mode * feat: report every CPU flag in node facts * feat(ui): node table on the dashboard, every CPU flag and a readable topology The dashboard's nodes section is the Nodes page table, open by default, and a row opens that node. Ready reads green, capacity sorts by most available, and the processor's features tip lists every flag. Topology draws one row per port with switches in a muted card, highlights a node's links on hover, and offers a left-to-right layout beside top-down. * chore(ui): rebuild dist * fix: align the CPU facts fields * fix: bound the network test server start and read ARM CPU features and cores * chore(ui): rebuild dist * test(ui): pin the instances baseline clock and take the screenshots from CI's Playwright image * fix: retry a network test claim whose holder released it mid-check
feat(lambda): start the bootstrap unprivileged with no_new_privs (#1452 )

+## Seal-quota-override capability
+
+`AccountQuotaOverrideSealCapabilitySubject(node)` (`admission.v1.AccountQuotaOverrideSealCapability.<node>`) is a per-node, read-only request/reply route on which `operator/accountlifecycle` asks one configured gateway whether it supports the quota override seal, immediately before every seal attempt.
+The quota owner (`domains/admission/quota`) owns it: `awsgw` serves it with no queue group, so a request addressed to one node reaches only subscribers configured as that node, and two gateways sharing a node ID both answer.
+The consumer's quota seal reaper probes every configured node that runs `awsgw` and sends no seal request unless every one answers compatible.
+
+`AccountQuotaOverrideSealCapabilityVersion` is a claim about the whole binary's writers, not about the responder: version 1 means every quota override writer in the binary is revision-guarded and refuses a sealed record, and the binary serves the seal subject.
+A gateway binary without this responder has no subscriber, so the probe for that node reads as incomplete (`no-reply`), the same as a stopped or partitioned node.
+The reply proves nothing beyond the moment it was sent: a gateway downgraded or replaced after a successful probe is outside the guarantee.

+# Lambda v1 contracts
+
+This package will own the Lambda process contracts declared by ADR-0009:S13.
+It holds the L-GUEST declaration and, in `guest.go`, the connection vocabulary both ends share: the scope, the URI SAN roles, the ALPN identifier and the fw_cfg entry names. The transport and authentication are decided (ADR-0009:S17); the invocation message types and framing are not chosen, so no message types are defined here.
+It is not an AWS tenant-facing API.
+
+## L-GUEST: node executor to guest agent
+
+**Owner:** the Lambda domain.
+
+**Producers and consumers:** the node-local executor (`runtime/compute/lambda`) and the in-guest Lambda agent (`agents/lambda`), in both directions.
+
+**Operations:** bootstrap with scoped material, readiness, invoke, completion, bounded logs, shutdown.
+
+**Transport:** TCP over the microVM's network (ADR-0009:S17).
+The agent dials one connection to a listener the executor owns for the environment, and the guest exposes no listener for host control.
+At most one authenticated control connection is active per environment, and the agent may reconnect; how a prior connection and its in-flight work are handled is open (ADR-0009 M1).
+The network is shared and untrusted: no source address, port or bridge membership is identity or authority.
+Tenant code may be able to reach the listener, but it cannot open the agent's connection or key material, so any connection it makes fails authentication.
+
+**Authentication:** mutual TLS 1.3, bound to the environment ID and realization generation, using material the user runtime cannot read (ADR-0009:S17).
+For each generation the executor creates ephemeral self-signed host and guest certificates whose single URI SAN is `spinifex-lambda://<Region>/<account>/<function ID>/<environment ID>/<generation>/<role>`, with role `host` or `guest`.
+Each end validates the peer certificate against the one pinned peer certificate and separately requires that URI SAN with the opposite role; hostname verification is not relied on.
+ALPN carries the L-GUEST major version, `spinifex-lambda-guest/1`, and an unsupported version fails the handshake.
+Under TLS 1.3 the guest's handshake can complete before the host refuses its certificate, so the guest treats the connection as accepted only after the host's first message.
+
+**Bootstrap material:** the executor passes these fw_cfg entries under `opt/spinifex/lambda/`, and the agent reads them as root and unloads `qemu_fw_cfg` before user code starts.
+
+| Entry | Content |
+|---|---|
+| `guest-key` | Guest private key, PEM |
+| `guest-cert` | Guest certificate, PEM |
+| `host-cert` | The one pinned host certificate, PEM |
+| `expect` | `<Region>/<account>/<function ID>/<environment ID>/<generation>` |
+| `host-addr` | Host listener as `host:port` |
+
+The guest's own interface settings come from `opt/spinifex/netcfg`, the entry other system VMs use.
+The agent unloads `qemu_fw_cfg` even when an entry is missing, and refuses to start if the fw_cfg tree is still readable afterwards.
+Until the message format exists, the agent authenticates and holds the connection but accepts no host message and starts no user code.
+
+**Authority:** one environment's attempt only.
+The user runtime never holds these keys, and sharing the guest with the agent gives user code no platform authority.
+
+**Idempotency and fencing:** an invoke carries the attempt-grant identity and the attempt ID.
+The agent accepts a run command only under a current grant, and a completion under a superseded grant is discarded and reported.
+How a grant is enforced and proven ended is open (ADR-0009 M1).
+
+**Errors and versions:** the agent and executor fail closed on an unknown protocol version or an identity mismatch.
+
+**Readiness:** environment readiness needs authenticated, current-generation agent evidence; a running hypervisor process does not count.
+
+**Payloads:** the contract must carry a synchronous payload and response of up to 6 MB and an asynchronous payload of up to 1 MB, plus framing, over a path whose size bound is declared.
+How payloads move is open (ADR-0009 M3).
+
+### Compatibility boundary
+
+The agent ships inside the runtime image pinned by each published version, so it is outside the coordinated release train.
+The executor supports every L-GUEST major carried by a still-supported runtime image.
+Retiring an image follows a published runtime-deprecation lifecycle that blocks create and update before it blocks invoke.
+
+Evidence required before the first agent image ships: a function on an old image invoked by a new executor, and the reverse during rollback.
+
+## L-RUNTIME
+
+The guest agent serves the AWS Lambda Runtime API, version `2018-06-01`, to the user runtime at `AWS_LAMBDA_RUNTIME_API`.
+Spinifex does not version this AWS contract, and conformance is measured against AWS.

 ### SQS System Instances

-These commands start the first SQS system instances on one node. They do not serve the SQS API, and a bound VM is not a ready service.
+These commands enable SQS on a single-node cluster and start its one system VM.
+A bound VM is not a ready service: `spx admin sqs status` reports readiness.

-Both send a signed `spinifex` admin action (`EnsureSQSWorker`, `EnsureSQSStore`) to the AWS gateway using the standard AWS credential chain, for example `AWS_PROFILE=spinifex`. The caller must be in the super-admin account (`000000000001`) and hold `spinifex:<Action>`. The VMs, volumes, private VPC and ENIs belong to the system account (`000000000000`). `--endpoint`, `--region` and `--ca-bundle` default to this node's gateway, region and `config/ca.pem`; off a node, `--endpoint` and `--region` are required. Each call waits up to 11 minutes.
+The SQS VM runs two processes on one encrypted data volume: the Region's dedicated SQS NATS server, which listens only on the guest's loopback address and is separate from platform NATS, and the worker, which serves SQS owner calls from that local store. The worker starts serving only after the local store answers and the receipt-signing key on the volume matches the fingerprint the platform recorded.
+
+SQS supports only a fresh single-node install. A worker record without a supported launch contract, or any record of the separate SQS store VM from an earlier dev build, cannot be upgraded: `enable` refuses it, and any existing volume is kept, not inspected, emptied or replaced. An existing separate store VM is refused on relaunch with its volume kept, and an existing worker VM is not restarted into a supported mode; upgrading such an install is unsupported.
+
+**Do not put tenant production data in SQS.** SQS-managed per-message encryption is not implemented: `GetQueueAttributes` reports `SqsManagedSseEnabled=false`, and a request to enable SSE-SQS or SSE-KMS is rejected.
+The SQS data volume must be encrypted, which is a separate layer under every queue and not SSE.
+There is no `DeleteQueue` or `PurgeQueue`, so a queue and its unexpired messages cannot be removed once created.
+Retention is checked when a message is received, against the queue's retention at that moment, and nothing deletes an expired message: the store drops a body only at its age backstop of 14 days and 1 hour.
+So a message past a short retention can be delivered again if `MessageRetentionPeriod` is later raised while its body is still stored.
+Account termination does not yet remove SQS queues or messages, and there is no disable: the VM's volume, receipt key and data are kept.
+
+Each sends a signed `spinifex` admin action (`EnableSQS`, `DescribeSQS`, `EnsureSQSWorker`) to the AWS gateway using the standard AWS credential chain, for example `AWS_PROFILE=spinifex`. The caller must be in the super-admin account (`000000000001`) and hold `spinifex:<Action>`. The VM, volume, private VPC and ENI belong to the system account (`000000000000`). `--endpoint`, `--region` and `--ca-bundle` default to this node's gateway, region and `config/ca.pem`; off a node, `--endpoint` and `--region` are required. `ensure-worker` and `enable` wait up to 11 minutes, and `status` up to 1 minute.

 | Command | Flags | Description |
 |---------|-------|-------------|
-| `spx admin sqs ensure-worker` | `--node` (required), `--instance-type` (required), `--endpoint`, `--region`, `--ca-bundle` | Launches the Region's one SQS worker VM on `--node`, or reports the VM already bound there: node, region, instance, instance type and generation. The worker is pinned to its first node; another node is refused with `InvalidParameterValue`, and there is no takeover. It gets a private system VPC with one /24 subnet and no internet gateway, NAT or Elastic IP, and an encrypted 1 GiB system-account data volume on which the guest generates its own store key. The platform records only the public key. A different `--instance-type` is accepted only while no volume, network interface or launch step has been attempted; once any has, it is `IncorrectState`, whether or not the step completed. |
-| `spx admin sqs ensure-store` | `--node` (required, the worker's node), `--instance-type` (required, more than 512 MiB memory), `--volume-size-gib` (required, 1–16384), `--endpoint`, `--region`, `--ca-bundle` | Launches the Region's SQS store VM on the worker's node with an encrypted system-account data volume, or reports the VM already bound there: node, region, instance, instance type and address. Needs the worker bound with its public key recorded, else `IncorrectState`. The store accepts only that key. A different size, type or key than the first call is `IncorrectState`. |
+| `spx admin sqs enable` | `--node` (required), `--instance-type` (required, more than 512 MiB memory), `--volume-size-gib` (required, 1–16384), `--endpoint`, `--region`, `--ca-bundle` | Records SQS as enabled for the Region, pinned to `--node`, then launches or reports the SQS VM there. The desired state is recorded first, so rerunning the command resumes an interrupted enable. More than one node in the cluster is refused before anything is recorded. A worker record with a missing or unsupported launch contract, or a record of the separate store VM, is also refused before anything is recorded or launched; any existing volume is kept, and upgrading it is not supported. |
+| `spx admin sqs status` | `--endpoint`, `--region`, `--ca-bundle` | Shows the requested state, node, generation, VM state, receipt key state, whether a worker is polling this gateway, whether this gateway serves the SQS API, and `Ready`, which is true only when all of them hold. `Unsupported` names a record whose missing or unsupported launch contract blocks enable. |
+| `spx admin sqs ensure-worker` | `--node` (required), `--instance-type` (required, more than 512 MiB memory), `--volume-size-gib` (required, 1–16384), `--endpoint`, `--region`, `--ca-bundle` | Launches the Region's one SQS VM on `--node`, or reports the VM already bound there: node, region, instance, instance type and generation. The VM is pinned to its first node; another node is refused with `InvalidParameterValue`, and there is no takeover. It gets a private system VPC with one /24 subnet and no internet gateway, NAT or Elastic IP, and an encrypted system-account data volume of `--volume-size-gib` that holds the queue data and the receipt-signing key the guest creates on first boot. The platform records only the key's fingerprint. A different `--instance-type` is accepted only while no volume, network interface or launch step has been attempted; once any has, it is `IncorrectState`, whether or not the step completed. A different `--volume-size-gib` than the recorded one is `IncorrectState`. |

 `ServiceUnavailable` never proves that no SQS resources exist, because an earlier attempt may already have created some. Its message says what it does establish. When no node serves the subject, this request was not delivered. When a volume create was not sent, that particular create did not happen. When the node cannot boot the guest yet or its launcher lacks a capability, this request stopped before allocating or recording anything. When the gateway times out waiting for the node's reply, nothing is known: the launch may still be running, so never assume it created nothing. In every case, call the command again with the same arguments. A retry first checks the durable record of the attempt and continues only when that is safe; it can proceed to the first launch after a create that was proven unsent, and otherwise reports the recorded outcome as bound or `IncorrectState`, or returns `ServiceUnavailable` again. `IncorrectState` from a volume, network interface or launch step means that step was recorded as sent but its outcome was never observed. It is never resent, the message names the volume when its ID is known, and no tool reconciles it yet: recovery is manual.

-`bound` says only that the VM was launched for the current record. The worker decides store readiness itself, by checking that the store is bound to its own public key and that a NATS connection with that key succeeds; nothing reports that readiness to the operator. The worker-to-store connection does not authenticate the store server. Real VPC routing, IMDS and gateway TLS from the guest, and worker-to-store traffic on a real interface have not been tested.

-### SQS store system instance (not wired)
+### SQS system instance (operator-launched)

-Spinifex can build, install, launch, restart and give storage to a dedicated SQS store microVM, but nothing calls any of it.
-No SQS API, domain service, admin command or daemon start-up path creates a store, so none of this is in production use.
+One system-owned microVM per Region runs both the SQS store and the SQS worker as separate processes, on one encrypted data volume pinned to one node (ADR-0011 Amendment 5, ADR-0012 Amendment 6).
+Only an operator activates it with the super-admin `EnsureSQSWorker` or `EnableSQS` actions; nothing starts it at daemon startup, and platform NATS is neither used nor changed for SQS data.
+This first profile is fresh single-node only: a host cluster of more than one node is refused before anything is recorded or allocated, and there is no disable.

-The guest image is built by `make build-sqs-store-microvm-image`, separate from the load balancer image, and bundles the `nats-server` version pinned in `go.mod` plus the ext4 tools.
-Release tarballs carry it as `microvm-sqs-store/`, and `setup.sh` installs it to `/usr/share/spinifex/microvm/sqs-store/`.
-A release without a complete image removes any previously installed one, so a launch is then refused rather than booting a stale image.
+`make build-sqs-worker-microvm-image` builds the one `sqs-worker` image: the static `sqs-worker` binary, the pinned `nats-server`, the ext4 tools and a network `/init`; releases ship it as `microvm-sqs-worker`, which `setup.sh` installs to `/usr/share/spinifex/microvm/sqs-worker`.
+At boot the guest reads three firmware config values under `opt/spinifex/sqs-worker/` (the data disk's serial, its Region and the gateway URL on this node's mgmt bridge) and refuses before touching any disk if one is missing or malformed.
+It selects exactly one disk with that serial, runs `e2fsck -p`, mounts it at `/data` and confirms from `/proc/self/mountinfo` that the whole disk is what is mounted; the guest never formats.

-At boot the guest reads three firmware config values: the data disk's serial, an IPv4 address on one of its interfaces, and one NATS user NKey public key.
-It mounts exactly one matching disk at `/data` after `e2fsck -p`, refuses a missing, duplicate, unformatted or unrepairable disk, and never formats.
-JetStream keeps its data on `/data` with `sync_interval: always` (ADR-0011:S3), `max_payload: 2MiB` admits a full 1 MiB SQS message with its headers (ADR-0011:S4), and the server listens only on that address and accepts only that key.
-On shutdown the store is stopped before `/data` is unmounted; a store that survives SIGKILL leaves every mount in place.
+The store is a dedicated `nats-server` listening only on `127.0.0.1`, with its JetStream directory at `/data/jetstream` and `GOMEMLIMIT=512MiB` (ADR-0011:S11), so nothing outside the VM can reach it and it needs no network identity of its own.
+The store starts only after the receipt key is settled, and the worker connects only after the store answers JetStream account info, so an unavailable store never appears ready.

-A launch uses the versioned subject `system.LaunchSQSStore.v1`, which a daemon without this code does not serve, so it fails with no responder instead of booting another guest.
-The legacy `system.LaunchInstance` path refuses the store kind on both send and receive.
-Every input check runs before capacity is reserved, and the data volume must be an available system-account volume.
-It is mounted through the normal EBS path and detached, never deleted, on terminate, which is the protection standard EBS gives today and nothing stronger.
-CPU mitigations stay enabled for the store, unlike the load balancer.
-A successful launch means the VM is running, not that NATS is ready.
+The receipt-signing key lives on the data disk under `/data/sqs-worker-key`, written to a temporary file, synced, renamed and its directory synced before its fingerprint is recorded.
+`domains/sqs/workerident` holds the platform's receipt-key state on the worker's identity record, beside its generation, claim, pinned node and volume: `pending` is set only when the record first creates its volume, and `recorded` holds the fingerprint.
+Under `pending` the guest may create a key, or reuse a valid key it already wrote before a crash, only while no `/data/jetstream` directory exists; any store data under `pending` refuses, because it proves the volume is not new.
+Under `recorded` a missing, unreadable or different key refuses the boot and is never regenerated; a record with no receipt-key state is refused as not proven new.
+`RecordReceiptKey` writes the fingerprint by compare-and-swap that re-checks the current instance, generation, claim and volume, and a lost reply is answered by reading the record again, never by a new key.
+A replacement worker reuses the pinned volume and keeps its predecessor's receipt-key state.

-The instance record keeps the store's non-secret guest settings so a restart on the node that launched it rewrites the firmware config files.
-A relaunch on any other node is refused, and cross-node recovery never claims a store.
-Both checks exist only in daemons with this code: an older daemon can still claim and relaunch a store elsewhere, and an explicit start served by another node claims the instance before its relaunch is refused.
+The worker reaches the gateway over TLS 1.3 trusting only the cluster CA, signing with instance-role credentials from the metadata service only.
+The internal `spinifex-sqs` actions are `ClaimReceiptKey`, `RecordReceiptKey`, `PollWork` and `CompleteWork`; the gateway admits only an assumed-role session of `sqsWorkerRole` in the system account and resolves the instance through `workerident.Authorize`, a point-in-time check against the current bound record.
+The worker pulls tenant work from its own node's gateway relay and posts results back, so no SQS payload crosses platform NATS; the relay holds a bounded, in-memory set of waiting requests and answers `ServiceUnavailable` when it is full or no worker is polling.

-`domains/sqs/storevolume` prepares a fresh data volume, because the guest never formats.
-It checks for `mkfs.ext4` and `qemu-img` before allocating, creates the volume in `creating`, writes an empty ext4 image to it over NBD on the local node, unpublishes it, and only then makes it `available`.
-While a volume is `creating`, attach, delete, modify, force-detach and snapshot are refused.
-A volume is deleted only after a confirmed unpublish; any publish error, an unconfirmed unpublish or a failed release keeps it and reports its ID, with its state reported as unknown after a failed release.
+`EnsureSQSWorker` takes a `NodeId`, an `InstanceType` and a `VolumeSizeGiB`; the instance type's memory must exceed the store's 512 MiB limit, and a later request for a different type or size is refused as `IncorrectState`.
+`EnableSQS` records the Region's desired state, pinned to one node, and then ensures the worker; `status` reports it ready only when the worker is bound, polling and the tenant API is registered.
+A store launch record or VM from the earlier separate-store design, or a worker record without a supported launch contract, is refused with its volume kept: enable stops before recording anything, and a relaunch of an old store VM is marked failed rather than started.

-Evidence is local only: unit tests, real QEMU boots against disposable scratch disks, and one run of the preparer against the `qemunbdd` provider whose volume kept acknowledged writes across a reboot.
-Viperblock, volume encryption, the EC2 volume record path, multiple nodes and host reachability of the guest address are not tested.
-Credential issuance and rotation, store placement and NATS readiness checks do not exist, and there is no failover: a lost node leaves its store unavailable.

-### SQS worker guest (operator-launched)
-
-The shared SQS worker guest holds the SQS store's client credential, so that no platform component does (ADR-0011:S2).
-Only an operator activates it, with the super-admin `EnsureSQSWorker` action described below; nothing starts it at daemon startup, and no worker service runs after boot.
-
-`make build-sqs-worker-microvm-image` builds it with the store image's script and network `/init` under `SQS_MICROVM_PROFILE=worker`; it carries the static `sqs-worker` binary and the ext4 tools, no `nats-server`, and an empty `/data` mountpoint.
-Releases build it beside the store image and ship it as `microvm-sqs-worker`, which `setup.sh` installs to `/usr/share/spinifex/microvm/sqs-worker` with the store image's rules: a release without it removes an earlier one, and an incomplete one is refused.
-At boot `sqs-worker boot` reads three firmware config values under `opt/spinifex/sqs-worker/`: the worker disk's serial, its Region and the gateway URL; none is a first-store decision, because a static value survives a guest reset.
-A missing, empty or malformed value refuses before any disk is touched.
-
-It selects exactly one disk with that serial, runs `e2fsck -p`, mounts it at `/data` and then confirms from `/proc/self/mountinfo` that this disk, as a whole ext4 filesystem, is what is mounted there; an empty mountpoint, a foreign mount or a failed check or mount refuses, and the guest never formats.
-Only then does it ask the gateway for the current decision with `ClaimFirstStore`, signed by `internal/sqsworkergw` with credentials from the instance metadata service only (`gwsign.NewInstanceRole`, no environment, profile or static-key fallback), over TLS 1.3 that trusts only the cluster CA from `opt/spinifex/ca-cert` and never follows a redirect.
-Under that decision `workerkey.Acquire` creates the key on `/data/sqs-worker-key`, owner-only and synced, records only its public key and then uses it, or loads the recorded key; a missing or different key once one is recorded refuses and is never replaced.
-The VM can start before its launch binds the instance, so its first calls are legitimately `AccessDenied`; that denial creates nothing and is asked again, as are a lost reply and a `ServiceUnavailable` or `Throttling` refusal, all within one bound (60 attempts 5 seconds apart), after which a worker that was never bound, or was replaced, refuses the boot.
-A signature or other refusal, or an answer that is neither "create" nor one valid public key, refuses the boot at once.
-
-`domains/sqs/firststore` is the SQS domain's first-store decision: one record per Region in the `spinifex-sqs-first-store` KV bucket moves from `claimed` to `key-recorded` to `launch-intent` under compare-and-swap, bound to the worker's instance ID, claim ID and generation.
-A claim authorizes key creation only while no public key is recorded; once one is, every claim returns only that key, and a store launch intent needs it recorded first.
-An older generation, a different identity at the same generation or an unreadable record authorizes nothing, and the record holds no private key material.
-Reads are stream message gets answered by the stream leader, never direct gets a lagging replica can answer, and every authorizing answer is also confirmed by a compare-and-swap at the revision it read, so a stale or unavailable read authorizes nothing.
-The authenticated caller that will carry this decision must derive the worker's instance ID and generation from authoritative instance state; a generation supplied in a request cannot itself authorize a takeover.
-
-`domains/sqs/workerident` is that authoritative instance state: one record per Region in the `spinifex-sqs-worker-identity` KV bucket holds a monotonic generation, claim ID, pinned node and encrypted data volume, and moves from `launching` to `bound` to `stopped`, or from `launching` to `failed`, under compare-and-swap.
-A launch intent is refused while the previous attempt is `launching` or `bound`, including one whose outcome is unknown, so only one caller ever holds an intent to start a VM on the pinned volume.
-A replacement takes the next generation only after `FailLaunch` or `RecordStopped` records that nothing holds the volume, and each request names the generation it supersedes, so a replayed request cannot take a generation it never observed; there is no automatic takeover.
-The launch path then raises the first-store fence to the successor's generation with `firststore.Fence` before `BeginLaunch`, which refuses a replacement until a leader read shows that fence; the fence only rises, and `firststore` refuses every call from a generation below it.
-Only the current claim ID is recorded, so claim IDs are minted fresh per attempt and a VM launch must be idempotent on generation and claim together.
-Binding writes the instance's index entry first and then binds the record to that instance.
-The index is only a lookup: `Authorize` accepts an instance only while the Region's record is `bound` to exactly that instance, generation and claim, confirmed by a compare-and-swap at the leader-read revision, so an old, orphaned, rewritten or unbound entry authorizes nothing.
-A same-instance reboot keeps its instance ID and identity; a replacement takes a new generation, and the first cut refuses another node or data volume and an unencrypted volume, although the encryption flag is the caller's claim and the launch wiring must verify it from the volume's metadata.
-Both buckets are opened through `OpenDurableKV`, which refuses an existing bucket whose effective stream configuration could expire, evict, lose, lag or refuse records: non-limits retention, an age, per-message or delete-marker TTL, memory storage, asynchronous flush, a size, count or message-size cap, a discard policy other than discard-new, unacknowledged writes, a sealed stream, a mirror or sources, or fewer replicas than the cluster needs.
-`workerkey.Acquire` drives that decision: it syncs a new key to disk, records its public key and only then returns it, so a crash before recording reuses the key already on disk.
-
-`domains/sqs/awsapi/worker` carries the decision to the worker as `ClaimFirstStore` and `RecordWorkerPublicKey`, served under the internal `spinifex-sqs` signing service, which no AWS SDK signs for; the public AmazonSQS action inventory is untouched.
-The gateway admits only an assumed-role session of `sqsWorkerRole` in the system account, then the role's policy, and only then resolves the session name, the instance ID STS set, through `workerident.Authorize`; the request carries no identity, and any parameter beyond the action's own is refused.
-The first-store identity is the current record's instance, claim and generation, and a worker bound to another Region is refused.
-A request that passed `Authorize` just before a confirmed stop and replacement still carries the old generation; the fence was raised before the successor began, so `firststore` refuses it whether or not the successor has claimed yet.
-The adapter never logs a caller-chosen parameter name, because one could carry a secret.
-`RecordWorkerPublicKey` accepts only a valid public user key, so a seed is refused without being recorded, logged or echoed.
-The gateway binds both buckets per request and never creates them, so it provisions nothing and answers `ServiceUnavailable` until a worker launch has created them; the worker launch below ensures the role.
-The private key stays on the worker disk; the guest logs and publishes only the public key to `/run/sqs-worker/public-key`.
-
-`domains/sqs/workerlaunch` realizes the worker on the node it runs on, its only node: a bound record is returned as is; otherwise it takes the intent, then on the first launch marks the intent's one volume create, prepares the volume and records its ID, reads the volume's own record and refuses it unless encrypted, ensures the role, finds or creates the network for the claim and reads the recorded store key, and marks the intent dispatched before launching.
-A dispatched launch is never sent again: a lost reply or error leaves the intent `launching` and dispatched, and every later call returns `ErrOutcomeUnknown` until the outcome is reconciled, since the launch path is not idempotent.
-A failure before dispatch leaves an undispatched intent that the next call resumes with the same claim; a confirmed stop or failure is replaced only after `firststore.Fence` excludes the old generation, reusing the pinned volume.
-The launch passes no store decision or key: the guest asks the gateway at boot.
-The intent exists before any volume, so concurrent first launches allocate nothing for the losers. A Prepare proven to have sent no create withdraws the mark and returns `ServiceUnavailable`, or `UnsupportedOperation` when the cluster storage key is not configured, and a retry may prepare the volume; a create that may have applied is never sent again, and every later call returns `IncorrectState` until it is reconciled. A volume the call knows of but cannot use is reported with its ID in a `VolumeError` and left in place, never deleted. An intent that has sent no create may be re-typed; one that has keeps its type until replaced. The worker role is created with EC2-only trust, and an existing role is checked for that trust before any policy is granted; the instance profile must carry exactly the worker role, and one holding any other role is refused unchanged.
-The daemon's `LaunchSQSWorkerInstance` boots the `sqs-worker` image through the same direct-boot path as the store, with the data volume attached at boot and kept on terminate, a required instance profile, and a required mgmt NIC; it re-reads the volume's own record and refuses one that is not available and encrypted, before anything is allocated.
-Its firmware config adds the gateway URL on this node's mgmt bridge and the cluster CA from the daemon's own trust store; the caller cannot supply either, and no value written is secret.
-A relaunch rebuilds that config from the VM record on the node that launched it and is refused anywhere else, and membership takeover already skips SQS-managed instances.
-`sqsWorkerRole` is ensured in the system account granting exactly `spinifex-sqs:ClaimFirstStore` and `spinifex-sqs:RecordWorkerPublicKey`, from the `domains/sqs/workerrole` contract the gateway gate also reads; an existing role whose trust admits more than the EC2 service is refused.
-
-Evidence is local only: unit tests with a fake firmware config, sysfs and mount table, tests running the boot through the real client against the real `spinifex-sqs` registration and records, and QEMU boots of the built image against disposable scratch disks and a host-side test gateway and metadata service, showing the first boot creates the key, reboots reuse it, a key lost after recording is never replaced, and the seed reaches no log or request.
-The worker's network is a private SQS system VPC per Region, built by `systemvpc.EnsurePrivate` from the `[sqs]` supernet (default `10.240.0.0/14`): one VPC and one /24 subnet, with no internet gateway, NAT gateway, EIP, route table or daemon-to-store node port. Each launch claim gets one ENI in that subnet, in the VPC default security group, found again by its claim on a retry; two ENIs for one claim are refused. The launch intent is marked before the one create is sent, so a create whose ENI is not yet visible is never sent again: the launch fails closed with `IncorrectState` until the ENI appears or the outcome is reconciled. Worker-to-store TCP and the guest's route to the metadata service are not yet proven by any traffic test.
-The super-admin `EnsureSQSWorker` action on the internal `spinifex` operator service takes a `NodeId`, which must be a node of this cluster and a single subject token, and an `InstanceType`, and sends a request to `sqs.worker.Ensure.v1.<node>` with no queue group, so only that node answers and the worker stays pinned.
-That node's daemon re-checks the node the request names and the instance type, and refuses as `ServiceUnavailable` before allocating a volume or network or recording an intent unless the worker image's kernel and initramfs are non-empty files, its mgmt bridge exists and the cluster CA is readable; a call after the image is installed then launches.
-It then runs its one composed launcher for its own Region, one launch at a time, in the daemon's own context with a 30-minute bound, so a caller's timeout does not cancel it.
-A reply lost to that timeout is reported as `ServiceUnavailable`; calling again reports the bound worker, or `IncorrectState` for a dispatched launch whose outcome is unknown, which is never resent; a Region pinned to another node is refused as `InvalidParameterValue`.
-The reply names the bound VM's node, Region, instance ID and generation; bound is not ready, and it says nothing about the guest's boot, its key or the store.
-Stop/detach evidence for `RecordStopped` is not wired, the guest's metadata route and gateway TLS on a real ENI and worker-to-store TCP are unproven, and Viperblock's at-rest key is held by the platform.
-
-The worker identity record holds the instance type of its generation; a request for another type is refused as `IncorrectState`, before dispatch and after binding, the reply names the recorded type, and only a replacement after a confirmed stop may change it.
-Operators call both actions with `spx admin sqs ensure-worker --node --instance-type` and `spx admin sqs ensure-store --node --instance-type --volume-size-gib`, signed for the `spinifex` service with the standard AWS credential chain like the other `spx admin` gateway commands.
-Each command refuses missing inputs before sending anything and reports only the bound VM; a bound VM is not a ready worker or store.
-The super-admin `EnsureSQSStore` action takes a `NodeId`, an `InstanceType` and a `VolumeSizeGiB` and sends a request to `sqs.store.Ensure.v1.<node>` with no queue group; only the node the Region's worker is bound to can launch the store.
-That node refuses an instance type whose memory does not exceed 512 MiB, the store's `GOMEMLIMIT` under ADR-0011:S11; this is a floor, not a validated size, and no type is defaulted.
-It refuses before recording or allocating anything unless the store image and the cluster storage key are present, the worker is bound on this node, and that worker's identity has recorded its public key in the first-store decision, which it then advances to a launch intent.
-The store's own launch record in `spinifex-sqs-store-launch` holds only that public key, the claim, the node and the operator's instance type and size, and marks each step before its uncertain create: the volume, the ENI in the worker's private subnet, and the launch.
-A later request for a different instance type or size is refused as `IncorrectState`, before dispatch and after binding, and the reply names the type the store was launched with.
-A volume preparation that failed before sending any create, such as a missing `mkfs.ext4` or a scratch or format failure, withdraws its mark and returns `ServiceUnavailable`, so a retry may try again once the host is fixed.
-Any other marked step whose result is not visible is reported as `IncorrectState` and never resent; a volume that is not encrypted by its own record is refused as `UnsupportedOperation` with its ID kept, and the daemon re-checks the volume's encryption and the guest's size at launch.
-The daemon never receives the worker's seed; the store's NATS server accepts only that public key, and the reply's bound VM and address are not readiness, which only the worker can check.
-
-After boot, the worker's long-running `sqs-worker ready` step mounts and verifies its disk again and calls the internal `spinifex-sqs` `DescribeStore` action, which admits only the current worker and returns the bound store's address and recorded public key, or pending.
-It loads its key only if it matches that public key, then connects to the store's NATS on port 4222 with it and asks JetStream for account info, each pass bounded to 30 seconds.
-The step runs until shutdown with no overall deadline, so a store the operator launches at any time is picked up: it asks again every 5 seconds while the store is pending, not answering or the reply was lost, and re-checks a ready store every 30 seconds.
-A pass writes only the address and public key to `/run/sqs-worker/store-ready`; any failed pass removes that file, and so does the step's own exit.
-A start that finds shutdown in progress or no worker key logs once and waits in place rather than exiting, so init does not respawn it in a loop; shutdown stops it like a running watcher.
-Init respawns the step, at most once every 5 seconds, and every start removes a marker left by a watcher that was killed or crashed before the new watcher runs.
-A ready store that fails is noticed up to one re-check interval plus one bounded call later, so the marker can be up to about a minute stale.
-Shutdown blocks further respawns, removes the marker, and stops the watcher by its recorded PID and start time, escalating to SIGKILL after a budget; it unmounts the worker disk only once the watcher is confirmed gone, and a survivor leaves every mount in place.
-A mismatched key, a store that refuses the key, a key missing from the disk or an unclassified gateway refusal is asked again only every 5 minutes, so it never spins and still recovers if the operator fixes it; a missing key is never replaced.
-The NKey authenticates the worker to the store, but nothing authenticates the store to the worker: there is no TLS, so a pass means only that something at that address accepted the key.
-This is store readiness for the worker alone; there is no SQS API, and no production sizing or support is claimed.
+Evidence is local: unit tests, the guest shell test and an AWS SDK test that creates a queue and sends, receives and deletes a message through the real worker loop against a real local JetStream store and a restart.
+A real guest boot, its metadata route on a real ENI and the signed path on a live node are unproven, Viperblock's at-rest key is held by the platform, and SQS-managed message encryption is not implemented, so the profile must not hold tenant production data.

Moving packages has not made the record private.
 - `domains/ecs/taskdefinition` (deliberate duplication, not debt): private `getJSON`, `putJSON` and `keysWithPrefix` copy the raw-KV helpers in `domains/ecs` so the extraction keeps ECS's get/put/list error and recovery semantics.

+### IAM roles for service accounts in your workloads
+
+A pod gets an IAM role by running under a ServiceAccount that carries the role ARN in an annotation.
+No pod-spec wiring is needed.
+
+```yaml
+apiVersion: v1
+kind: ServiceAccount
+metadata:
+  name: app
+  annotations:
+    eks.amazonaws.com/role-arn: arn:aws:iam::123456789012:role/app-role
+```
+
+Every control plane runs a mutating webhook that acts on pod creation.
+When the pod's ServiceAccount has the annotation, the webhook adds these to each container and init container:
+
+- `AWS_ROLE_ARN` and `AWS_WEB_IDENTITY_TOKEN_FILE`, with a projected token volume named `aws-iam-token` mounted at `/var/run/secrets/eks.amazonaws.com/serviceaccount`.
+- `AWS_REGION`, `AWS_DEFAULT_REGION` and `AWS_STS_REGIONAL_ENDPOINTS`.
+- `AWS_ENDPOINT_URL_STS`, so the SDK calls the Spinifex STS endpoint.
+- `AWS_CA_BUNDLE`, pointing at `/etc/spinifex/ca-bundle/ca.pem`, a ConfigMap named `spinifex-ca-bundle` that is created in every namespace and holds the system roots plus the gateway CA.
+- `SSL_CERT_FILE` with the same path, only when the container does not set it. Clients such as the AWS Load Balancer Controller read this variable instead of `AWS_CA_BUNDLE`.
+
+Your workload still sets `AWS_ENDPOINT_URL` (or the per-service variable) for every service other than STS.
+
+The token audience defaults to `sts.amazonaws.com`.
+The expiry defaults to a value between 79200 and 86400 seconds and is clamped to 600 to 86400 seconds.
+Set them with the `eks.amazonaws.com/audience` and `eks.amazonaws.com/token-expiration` annotations on the ServiceAccount.
+The `token-expiration` annotation on the pod wins over the ServiceAccount.
+
+A container is left alone when it already has the role, region and regional STS settings, which is how the managed add-ons and your own explicit wiring are skipped.
+When some are present, the missing ones and the mount are added.
+Containers named in the pod's `eks.amazonaws.com/skip-containers` annotation (comma separated) are not touched.
+A pod whose ServiceAccount has no role annotation is not changed.
+
+The webhook fails open: if it cannot decide, the pod is created without injection.
+Each injection, skip and failure is logged with the namespace, pod and reason in the control-plane console log.
+Because it fails open, a pod that needs a role but starts without credentials is the symptom to look for, and the console log says why.
+
+The webhook listens on `127.0.0.1:8445` of each control plane, and each API server calls its own.
+Port 8444 is a different listener, the readiness check described above.
+
+Existing clusters get the webhook only when their control planes are replaced by the current `eks-node` image.
+No user-facing operation replaces a control plane, and automatic replacement does not currently work when the replacement reuses the failed member's IP.
+Recreate the cluster to adopt it.
+User-workload injection through a cluster created with an older image is not measured.
+
+### Add-on versions
+
+Add-on versions use the AWS form `v<x.y.z>-eksbuild.<n>`, for example `v1.40.1-eksbuild.1`.
+`DescribeAddonVersions` returns versions in this form, newest first, and every other add-on response reports the version the same way.
+Spinifex ships one EKS build of each upstream version, so `<n>` is `1` today.
+
+`DescribeAddonVersions` honours `addonName`, `kubernetesVersion`, `types`, `publishers`, `owners`, `maxResults` and `nextToken`.
+Each version carries `compatibilities` with the `clusterVersion`, the `platformVersions`, and a `defaultVersion` flag that is true for exactly one version per add-on and cluster version.
+A `kubernetesVersion` that Spinifex does not run returns no add-ons.
+
+`CreateAddon` and `UpdateAddon` accept the AWS form of a version in the catalogue.
+They also accept the bare upstream form, such as `1.40.1`, and Spinifex logs each use at Info.
+This is a Spinifex leniency that AWS does not offer, and it exists so that older scripts keep working.
+Any other value is refused with a message that names `addonVersion` and lists the supported versions, for example `v1.40.1-eksbuild.2`, `1.40` or `v1.40.1`.
+
+In Terraform, pass the AWS form to `aws_eks_addon.addon_version`, either as a literal or from `data.aws_eks_addon_version`.
+The AWS provider validates the format before it calls the API, so it rejects the bare form.
+Leaving `addon_version` unset still installs the catalogue default.

 ## Overview

-Spinifex installs on Oracle Linux 10.2 or a later 10.x release, running the UEK R8 kernel, on x86_64.
-The installer, the release tarball and the install steps are the same as on Debian; this page covers what the host needs first and what the installer changes on it.
-Follow it alongside [Single-Node Install](/docs/install).
+Spinifex runs on Oracle Linux 10.2, on the UEK R8 kernel, on x86_64 with an x86-64-v3 CPU (Intel Haswell, AMD Excavator or later).

-**Supported on Oracle Linux:**
+The host must be a dedicated Spinifex host: Spinifex claims every `tap*` device and owns libreswan's `ipsec.service`.

- A single node, or a cluster in which every node runs Oracle Linux; servers beyond the third join as compute nodes, as on Debian.
- Guests, VPCs, routed NAT, Elastic IPs, and Application and Network Load Balancers.
- Whole-GPU passthrough, on x86_64 GPU hosts (see [GPU Passthrough](/docs/gpu-passthrough)).
+**Not supported yet:** clusters mixing Oracle Linux with Debian or Ubuntu, SELinux enforcing, aarch64, Oracle Linux 9 or earlier, the Red Hat Compatible Kernel, a ZFS root, NVIDIA MIG and air-gapped installs.

-**Not supported on Oracle Linux yet:**
+## Instructions

- Clusters that mix Oracle Linux with Debian or Ubuntu nodes, on any release.
- SELinux enforcing, aarch64, Oracle Linux 9 or earlier, the Red Hat Compatible Kernel, a ZFS root, and NVIDIA MIG.
+Work through both tabs in order.

-Open vSwitch and OVN come from the CentOS NFV SIG, because Oracle ships neither for Oracle Linux 10.
-The NFV SIG is a community repository, and Oracle does not support the packages it publishes.
-Spinifex installs `openvswitch3.5` and `ovn25.03`, the versions Debian 13 ships, and its repository file lets the SIG supply nothing else.
-QEMU comes from Oracle's KVM Utilities repository, because only that build has the `microvm` machine type Spinifex load balancers boot on.
+:::tabs
+@tab 1. Prepare Oracle Linux

-An Oracle Linux node must be a dedicated Spinifex host.
-Spinifex claims every `tap*` device and owns libreswan's `ipsec.service`, which it keeps stopped on a single node and runs for its own tunnels on a cluster node, so VPNs, hand-run QEMU guests and libreswan tunnels of your own cannot share the host.
-Crypto policies other than `DEFAULT` and `FIPS` are untested, and so is Secure Boot.
+### Update and check the host

-## Prerequisites

 ```

-The kernel must be UEK R8 (`6.12.0-*uek`), and it must be the running kernel: an installed but not booted `kernel-uek` is refused.
-The CPU must be x86-64-v3 or newer (Intel Haswell, AMD Excavator or later), since the NFV SIG and KVM Utilities builds target it.
-The installer names any missing CPU flag.
-
-The installer adds `kernel-uek-modules` for the running kernel, which carries `openvswitch.ko` and pulls in `linux-firmware`, about 800 MB.
-Oracle publishes modules for each kernel separately, so a host running an old kernel may find its modules gone from the repository; the installer then stops and asks for a kernel update and a reboot.
-
-### SELinux
-
-Spinifex ships no SELinux policy yet, so SELinux must be permissive or disabled, both now and at the next boot.
-Oracle's images boot enforcing.

+### Create the br-wan bridge

-### WAN bridge with NetworkManager
-
-As on every OS, the host's uplink must already sit on a Linux bridge named `br-wan`, with the host address and default route on the bridge (see [Single-Node Install](/docs/install#prerequisites)).
-On Oracle Linux, NetworkManager owns `br-wan`; Spinifex leaves the bridge and its NIC to it and marks the links it creates itself as unmanaged.

-Create the bridge from the console, not over SSH on the NIC being moved, since the host loses its address while the profile changes.

-### Network access during install
+@tab 2. Install Single Node

-Besides `install.mulgadc.com` and the AWS CLI download, the install reaches `yum.oracle.com` for the Oracle Linux repositories, `mirror.stream.centos.org` for the NFV SIG packages, and `www.centos.org` for the NFV SIG signing key.
-An air-gapped install on Oracle Linux is not documented yet.
-
-## Instructions
-
-## Step 1. Install Spinifex
-
-Run the installer as a user with `sudo`, exactly as on Debian:
+### Install Spinifex

 ```bash
 curl -fsSL https://install.mulgadc.com | bash
 ```

-For a single node, continue with [Single-Node Install](/docs/install) from Step 2: `setup-ovn.sh --management`, `spx admin init` and `systemctl start spinifex.target`.
-IPsec stays off on a single node, because there is no peer to encrypt traffic to.
+The installer stops and masks firewalld; see [firewalld](#firewalld) before relying on any rule it held.

-For a cluster, prepare and install every node this way, then continue with [Multi-Node Install](/docs/install-multi-node) from Step 2.
-
-### Clusters
-
-Every node in an Oracle Linux cluster runs Oracle Linux.
-`install-node.sh` refuses a host list that mixes Oracle Linux with Debian or Ubuntu, but `spx admin join` does not check, so keep to one OS yourself when joining by hand.
-
-IPsec encrypts the Geneve tunnels between nodes and is on by default, as on Debian.
-On Oracle Linux it runs on libreswan, the IKE daemon Oracle ships, rather than strongSwan.
-Once the node's IPsec certificate exists, the daemon unmasks and starts `ipsec.service` and `openvswitch-ipsec.service`.
-`ovs-monitor-ipsec` then loads the node certificate, its key and the cluster CA into libreswan's NSS database at `/var/lib/ipsec/nss`, under nicknames that start with `ovs_cert`.
-
-The tunnels are plain ESP (IP protocol 50), as on Debian, negotiated over UDP 500.
-Open UDP 500, UDP 4500 and ESP between nodes: libreswan moves to UDP 4500 if it detects NAT between two nodes.
-The Spinifex host firewall opens all three to cluster peers; a firewall between the nodes must allow them too.
-While IKE to a peer fails, the node drops its Geneve traffic to that peer rather than send it in clear.
-The nft table `inet spinifex_ipsec_guard` drops outbound UDP 6081 from the encap address whose route carries no SA, which also covers the moments pluto flushes the xfrm policy table as it starts and stops.
-It is not persisted: `ipsec.service` puts it back at boot before ovn-controller builds the tunnels, and the daemon re-syncs it every 60 seconds.
-`spx admin init --ipsec=false` leaves the tunnels unencrypted, as on any OS.
-
-## Step 2. Know What the Installer Changed
-
-On Oracle Linux the installer makes these changes, which Debian hosts do not need:
-
- **Repositories.** It enables `ol10_UEKR8` and `ol10_kvm_utils`, and adds `qemu-kvm*` and `qemu-img*` to the `excludepkgs` of `ol10_appstream`, keeping any excludes already set, so a later AppStream build can never replace the KVM Utilities QEMU.
- **NFV SIG.** It writes `/etc/yum.repos.d/spinifex-nfv-sig.repo` with an `includepkgs=` list of the OVS and OVN packages, and imports the SIG key to `/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-NFV` only when its fingerprint is `35154228174901BEFA8E69A621465E289D2A76A7`.
- **OVS and OVN user.** Both run as root, as on Debian, through `OVS_USER_ID` and `OVN_USER_ID` in `/etc/sysconfig/openvswitch` and `/etc/sysconfig/ovn`.
- **DNS.** Where systemd-resolved is installed but not running, it saves `/etc/resolv.conf` to `/var/lib/spinifex-reset/resolv.conf.orig`, starts resolved behind NetworkManager and links `/etc/resolv.conf` to the resolved stub. It then checks that names still resolve and stops, printing the commands that put DNS back, if they do not.
- **chrony.** It appends `confdir /etc/chrony.d` to `/etc/chrony.conf` once, and writes its step policy to `/etc/chrony.d/spinifex.conf`.
- **`spx` under `sudo`.** Oracle Linux's `sudo` path leaves out `/usr/local/bin`, so the installer links `/usr/bin/spx` to `/usr/local/bin/spx`.
-
-The kernel modules list (`/etc/modules-load.d/spinifex.conf`) and the host firewall below apply on every OS.
-
-## Step 3. Replace firewalld Rules You Depend On
-
-The installer stops and masks firewalld, because with it running a packet must pass both firewalld's table and the Spinifex one, which silently breaks routed NAT, Elastic IPs and instance metadata.
-When firewalld was active, the installer turns on the Spinifex nftables policy in its place; pass `--firewall=on` or `--firewall=off` to choose yourself.
-
-firewalld's rules are not saved or migrated.
-The Spinifex policy filters inbound traffic only and opens 53, 443, 3000, 8443 and 9999 to any source.
-It accepts SSH from every IPv4 source until `$trusted_ssh_peers` in `/etc/spinifex/firewall/custom.nft` narrows it.
-Restate any other restriction you had, such as SSH limited to a management subnet, in that file; [Host Firewall](/docs/host-firewall) shows how.
-
-From the moment firewalld stops until the daemon first loads the Spinifex policy, the host accepts every connection.
-Uninstalling Spinifex leaves firewalld unmasked but disabled; it does not turn it back on.
-
-## Step 4. Keep the Host Updated
-
-Do not enable `dnf-automatic`.
-An Open vSwitch package upgrade restarts OVS, which interrupts guest networking, so update `openvswitch3.5`, `ovn25.03*` and `qemu-kvm*` in a maintenance window.
-Stay on the current Oracle Linux 10 minor release, which is what Spinifex is tested on.
-
-Before rebooting into a new kernel, check that its modules are installed, or OVS cannot start after the reboot:
+### Set up OVN networking

 ```bash
-rpm -q kernel-uek-core kernel-uek-modules
+sudo /usr/local/share/spinifex/setup-ovn.sh --management
 ```

-Each `kernel-uek-core` version needs a `kernel-uek-modules` of the same version; install a missing one with `sudo dnf install kernel-uek-modules-<version>`.
+### Initialize

-Track Oracle Linux security advisories (ELSA) for the host, the kernel and QEMU, for example with `dnf updateinfo list --security`.
-Those advisories do not cover the NFV SIG packages, so follow Open vSwitch and OVN security announcements for those.
+```bash
+sudo spx admin init --node node1 --nodes 1
+```

-## Step 5. Uninstall
+### Start services

-`/usr/local/share/spinifex/uninstall-spx.sh` removes Spinifex as on Debian.
-On a cluster node it also stops `openvswitch-ipsec.service` and deletes the `ovs_cert*` entries from libreswan's NSS database, so the node can join a different cluster; other NSS identities and your connection files in `/etc/ipsec.d` stay.
-It lists what it leaves in place on Oracle Linux: the repository changes and the SIG key, `OVS_USER_ID` and `OVN_USER_ID`, the OVS and OVN logrotate edits, the chrony include, `/etc/modules-load.d/spinifex.conf`, the SELinux mode, a masked `ipsec.service`, firewalld disabled, and any GPU passthrough configuration.
-`--purge-deps` is refused on Oracle Linux, because dnf cannot tell the packages Spinifex installed from the host's own; remove them with `dnf remove` yourself.
+```bash
+sudo systemctl start spinifex.target
+```
+
+### Verify
+
+```bash
+export AWS_PROFILE=spinifex
+aws ec2 describe-instance-types
+```
+
+If this returns a list of instance types, Spinifex is installed.
+Continue to [Setting Up Your Cluster](/docs/setting-up-your-cluster) to import an AMI and launch your first instance.
+:::
+
+**For a cluster**, prepare and install every node with the steps above, then continue with [Multi-Node Install](/docs/install-multi-node) from Step 2.
+Every node must run Oracle Linux.
+IPsec between nodes runs on libreswan, so open UDP 500, UDP 4500 and ESP between nodes on any firewall between them.
+
+## What the Installer Changes
+
+On Oracle Linux the installer also:
+
+- Enables `ol10_UEKR8` and `ol10_kvm_utils`, and excludes `qemu-kvm*` and `qemu-img*` from `ol10_appstream`.
+- Adds the NFV SIG repository as `/etc/yum.repos.d/spinifex-nfv-sig.repo`, limited to the OVS and OVN packages.
+- Installs `kernel-uek-modules` for the running kernel, about 800 MB with `linux-firmware`.
+- Switches DNS to systemd-resolved behind NetworkManager where resolved is installed but not running.
+- Links `/usr/bin/spx` to `/usr/local/bin/spx`, so `sudo spx` works.
+
+### firewalld
+
+The installer stops and masks firewalld and turns on the Spinifex nftables policy in its place; firewalld's rules are not migrated.
+The Spinifex policy opens 53, 443, 3000, 8443, 9999 and SSH to any source.
+Restate any restriction you relied on, such as SSH limited to a management subnet, in `/etc/spinifex/firewall/custom.nft`; see [Host Firewall](/docs/host-firewall).
+
+### Updates
+
+Do not enable `dnf-automatic`: an Open vSwitch upgrade restarts OVS and interrupts guest networking, so update `openvswitch3.5`, `ovn25.03*` and `qemu-kvm*` in a maintenance window.
+Before rebooting into a new kernel, check `rpm -q kernel-uek-core kernel-uek-modules` shows matching versions, or OVS cannot start.
+
+### Uninstall
+
+`/usr/local/share/spinifex/uninstall-spx.sh` removes Spinifex and lists what it leaves in place.
+`--purge-deps` is refused on Oracle Linux; remove packages with `dnf remove` yourself.

+# EKS cluster: delete lifecycle contract
+
+Contract under ADR-0003 S1 for the delete half of an EKS cluster's lifecycle, the half ADR-0003 S8 constrains.
+Create, update and the control-plane reconciler are out of its scope and keep the observed gaps recorded elsewhere.
+Paths are relative to `spinifex/` unless they start with `tests/`, which is relative to the spinifex repo root.
+Test names without a path are in `domains/eks/cluster/`.
+
+## Scope
+
+A cluster is a composite resource: its record at `clusters/{name}/meta` in the `eks-account-{account}` bucket names the dependants a delete must remove.
+In the system account those are the control-plane VMs and their root volumes, the endpoint load balancer with its target groups, the managed control-plane VPC and its network, and the spread placement group.
+In the customer account they are the egress address, the private-endpoint interface and security group, the cluster security groups, a cluster-owned internet gateway, and load balancers the in-cluster controller created.
+Node group workers and CSI-provisioned EBS volumes are never removed by a cluster delete.
+
+## Contract
+
+| Item | Behaviour | Evidence |
+|---|---|---|
+| Request | `DeleteCluster` validates, answers `ResourceNotFoundException` for an absent cluster, answers a `DELETING` cluster from its record, refuses a cluster with node groups with `ResourceInUseException`, records `DELETING` and returns. It waits for no teardown step. | `TestS8_EKSDeleteClusterReturnsBeforeTheTeardownCompletes`, `TestRLC1_EKSDeleteClusterNotFoundOnAbsent`, `TestS8_EKSDeleteClusterRefusesWhileNodegroupsExist`, `tests/e2e/eks` `TestEKS/DeleteCluster` |
+| Obligation | `DELETING` with `DeletingSince` on the record is the tenant's decision. No status writer moves a record off it, and a create launch still running adds its refs to it instead of overwriting it. | `TestS2_EKSDeletingIsStickyForStatusWriters`, `TestS2_EKSLaunchWriteAfterDeleteNeitherRevertsNorRecreates` |
+| Retry | A repeat delete answers `DELETING` from the record and starts nothing. | `TestS8_EKSSecondDeleteAnswersFromTheRecordWithoutASecondTeardown` |
+| Convergence | `convergeClusterDeletion` (`domains/eks/cluster/cluster_teardown.go`), started by the request and backed by `EKSDeletingReaper`, runs under a per-cluster in-process gate and the cross-node teardown lease, renewed on the service context. It acts only on a record that is `DELETING` when re-read. | `TestS8_EKSKickAndSameNodeSweepRunOneTeardown`, `TestS8_EKSTeardownLeaseOutlivesTheRequest`, `TestS7_EKSTeardownActsOnlyOnARecordedDelete` |
+| Retained cleanup | A failed step keeps the record `DELETING` with its refs and the error. The record is removed last, after its child records, and only if no ref appeared that the pass did not tear down. A record with a node group is never removed; a record that is not `DELETING` is refused before anything else is checked. | `TestRLC2_EKSBillableTeardownBeforeKVSweep`, `TestS2_EKSTeardownRemovesTheMetaLast`, `TestS2_EKSTeardownDoesNotSweepARecordChangedDuringTeardown`, `TestS7_EKSTeardownNeverRemovesAClusterWithNodegroupWorkers` |
+| Recovery | A teardown interrupted by a crash or a lost lease is finished by the reaper on any node. Failed passes back off from 90 s, doubling to a 30 min cap, and are never abandoned; `DeleteReapExhausted` only flags a long failure for an operator. | `TestS2_EKSTeardownResumesAfterAnInterruptedConverge`, `TestRLC4_DeletingReaperReDrivesWedgedTeardown`, `TestDeletingReaper_KeepsRetryingPastTheOldAttemptLimit`, `TestDeletingReaper_ResumesAnAlreadyExhaustedRecord` |
+| Visibility | `DescribeCluster` and `ListClusters` show the cluster `DELETING` until the record is removed, then `ResourceNotFoundException`. A failed pass shows one `INTERNAL_FAILURE` health issue naming the step, never the internal error. | `TestDescribeCluster_StuckDeleteShowsTheStepNotTheError`, `TestRLC2_EKSBillableTeardownBeforeKVSweep` |
+| New dependants | `CreateNodegroup` requires `ACTIVE`; `CreateAddon` and `CreateAccessEntry` refuse a `DELETING` cluster with `ResourceInUseException`. | `TestCreateAddonRefusesOnlyADeletingCluster`, `TestS2_EKSDeletingClusterAdmitsNoNewDependants` |
+| Subject budgets | Every `eks.*` request subject is classified by its handler's work in `eksSubjects` (`domains/eks/cluster/service_nats.go`) and keeps the 30 s budget; `eks.DeleteCluster` is request-scaled. A subject the gateway sends or the daemon serves that is not classified fails the table. | `TestS8_EKSSubjectBudgets` |
+| Late child records | No child record outlives the cluster or leaks into a later one of the same name. The teardown sweeps child keys again after removing the meta and stops the cluster's bootstrap subscriber, bootstrap refuses to write into a record that is gone or `DELETING`, the launch re-checks its record around seeding the creator's access entry, and a fresh claim clears whatever an earlier cluster left under the name. | `TestS2_EKSLaunchOvertakenByDeleteLeavesNoChildRecords`, `TestS2_EKSBootstrapWritesNothingIntoADeletingCluster`, `TestS2_EKSFreshClaimInheritsNoStaleChildRecords` |
+| Launch generation | The create launch's writes are fenced on the record's generation (`CreatedAt` and ARN). An overtaken launch never writes a newer cluster of the same name and releases only the instances it started, by ID. One whose record was swept recreates it as `DELETING` with its refs, so the teardown and reaper own the release. One whose record was marked `FAILED` merges its refs and releases what it built. | `TestS2_EKSOvertakenLaunchNeverWritesANewerClusterOfTheSameName`, `TestS2_EKSOvertakenLaunchHandsItsInfraToTheTeardown`, `TestS2_EKSLaunchMarkedFailedReleasesWhatItBuilt` |
+| Running launch | A create launch heartbeats its owner and time on the record (`LaunchOwner`, `LaunchHeartbeat`). The teardown keeps the record while that heartbeat is fresh, so the cluster reads `DELETING` throughout and never `ResourceNotFoundException` then `DELETING` again; the launch hands its refs over at its next write and starts the teardown when it returns. A heartbeat older than 90 s is taken as a crashed launch and no longer waited for, and recreating a swept record stays as the backstop. The launch's OIDC keypair writes are fenced on the record's generation. | `TestS2_EKSDeletedClusterNeverReadsMissingWhileItsLaunchRuns`, `TestS2_EKSCrashedLaunchDoesNotPinTheDelete`, `TestS2_EKSOvertakenLaunchCannotReplaceANewerClustersSigningKey` |
+| Bounded passes | One converger run is bounded at 15 minutes, so a hung step cannot hold the gate and lease; the timed-out pass is recorded and backed off. Waiting on node groups is not counted as a failed pass, and deleting the last node group resumes the delete. | `TestS8_EKSHungTeardownStepReleasesTheGate`, `TestS2_EKSLastNodegroupDeletedResumesTheClusterDelete` |
+| FAILED reclaim | Re-creating a `FAILED` cluster's name tears the old attempt down under the same gate and lease as a delete, and answers `ResourceInUseException` while another holder has it; the per-node teardown bound does not apply to it. | `TestS2_EKSFailedClusterReclaimRunsUnderTheTeardownLease`, `TestS2_EKSFailedClusterReclaimIsNotRefusedForCapacity` |
+| Tenant data | The teardown never deletes a CSI-provisioned volume or terminates a node group worker. | `TestS7_EKSTeardownNeverDeletesCSIVolumesOrWorkers`, `TestS7_EKSTeardownNeverRemovesAClusterWithNodegroupWorkers` |
+
+## Gaps
+
+1. Four `eks.*` handlers still hold their request for work that grows with the resource, and the subject table names them as not conformant: `CreateCluster` (reclaiming a `FAILED` cluster of the same name tears its infra down inline), `DeleteNodegroup` (one awaited terminate per worker), `UpdateNodegroupConfig` (one awaited launch or terminate per worker added or removed) and `RestoreSnapshot` (launches a control-plane VM and fences the old one inline).
+2. AWS's answer to a repeat delete on a `DELETING` cluster has not been observed; `DELETING` from the record is the chosen behaviour.
+3. Control-plane, load balancer and VPC resources in the system account are keyed by the bare cluster name, so a teardown by name can reach another tenant's same-named cluster.
+4. The teardown deletes load balancers the in-cluster controller created in the customer account, which AWS leaves behind.
+5. An overtaken launch's late write can still land under a newer cluster of the same name in the instant between that cluster's claim sweep and the old launch's generation check; it is bounded by one write, since the old launch stops at its next fenced write.
+6. The `FAILED`-name reclaim purge still runs inside the `CreateCluster` request (gap 1).

 `stopped` is danger because EC2 reads it that way, although RDS treats it as a resting state; splitting the map by service is its own change.

+Its tones are `success`, `progress` (the yellow `warning` token), `caution`, `danger`, `muted` and `neutral`.

+It shows every state lowercase with hyphens, as EC2 writes them, so EKS's `ACTIVE` reads `active` and Bedrock's `IN_PROGRESS` reads `in-progress`; the API value, filters and CLI panels keep AWS's case.
+A good or settled state is always green, never grey, and a status that is not an API state, such as a cluster's health, uses `StatusBadge` with a tone rather than a `Badge`.
+The orange of `caution` is kept clear of the primary accent's hue, which marks actions and never a status.

 `src/lib/nav.ts` is the one description of the console's navigation.
 The sidebar, the command palette and the breadcrumbs all read it, and `nav.test.ts` checks every destination against the generated route tree, so a renamed route fails a test rather than leaving a dead link.

- **Sidebar.** Groups take generic names rather than AWS's service marks: Compute, Databases, Authentication and Object Storage, not EC2, RDS, IAM and S3. Pages and the rest of the console keep the AWS names, and each group's `service` keeps its AWS name findable in the command palette, where typing it exactly ranks that group first.

 - **Breadcrumbs.** Service, then list page, then the resource or the create flow. A resource ID is set in mono. On a phone only the last crumb shows.
 - **Sign in.** The sign-in card sits over the shell on a light, barely blurred overlay rather than on a page of its own, so the console stays in view. The shell behind it is `inert`, which keeps pointer, keyboard and screen reader out of it until the user signs in.

 - **URL.** The panel is search state on the list route: `selected=<id>`, `tab=overview|monitoring|settings`, and `create=true`. Defaults are stripped, so a closed panel leaves the plain list address. Opening or closing a panel pushes a history entry, so Back closes it; a tab or filter change replaces the entry.
 - **Layout.** From `lg` (1024px) the panel is fixed to the right edge, full height below the header, flush with no outer margin, and it slides in over the list. The list keeps its width and columns underneath, so nothing reflows when a panel opens, and a soft gradient on the panel's left edge reads as the panel lying on top. Below `lg` there is no room to share, so the panel replaces the list as a full page with a back arrow. `useWideLayout` decides, through `matchMedia`.
 - **`DetailPanel`.** A header with the resource's own page (left) and close (right), the title and its ID, a summary of state and quick actions, then icon tabs with tooltips. Escape closes it unless a dialog or menu is open over it. Closing slides the panel out over 150ms, or at once under reduced motion. Each tab, and a create form, sits in its own error boundary, so a failed query shows in the panel and the list keeps working.
- **Contents.** `PanelSection` is a folding card, `PanelFields` and `PanelField` a label and value list, with `copy` for a one-click copy of IDs and addresses, and `PanelTags` the tag list. Create forms take an `onClose(id?)` prop: embedded, they hide their back link and heading, and a create selects the new resource.
+- **Contents.** `PanelSection` is a folding card, `PanelFields` and `PanelField` a label and value list, with `copy` for a one-click copy of IDs and addresses, and `InlineTags` the tag list. Create forms take an `onClose(id?)` prop: embedded, they hide their back link and heading, and a create selects the new resource.
 - **One component is both the panel and the page.** Each resource has a single details component (`InstanceDetails`, `VpcDetails`, `InternetGatewayDetails`) that takes `layout="auto" | "page"`. The list renders it as the panel; `/ec2/describe-instances/$id` and its kind render the same component as a page, as one centred column under a standard left-aligned heading, with state and actions on the right and text tabs. A feature added to the panel is on the page by construction, and the page ignores Escape and has a back arrow in place of close. Expanding the panel to its page keeps the tab, and query results such as fetched console output come along from the cache.
 - **A click on the list's background closes the panel**, as UniFi's does. A row selects another resource instead, and links, buttons and inputs keep their own behaviour. Selecting rows for a bulk action closes it too, so the bulk bar and the panel never compete.
 - **Actions.** State actions sit in the summary as a button group, and the rest go in an Actions menu, Unikraft style. Stop, Reboot and every destructive action confirm in a dialog.
 - **Loading.** A panel or page still loading shows `PanelSpinner`, a centred spinner on the background, not a grey skeleton block.
 - **`DetailCard`, `DetailRow` and `ListCard` are retired.** Every resource page uses the panel sections instead.

+### Tags
+
+`InlineTags` (`src/components/inline-tags.tsx`) shows a resource's tags in its panel and edits them in place.
+Each row has a pencil, which turns the key and value into inputs and becomes a tick to save, and a bin to remove the tag; `+ Add tag` appends a row being edited.
+Enter saves and Escape cancels the row without closing the panel.
+Every row saves on its own request through the service's own tagging call, and a failure shows beside its row.
+AWS has no rename, so changing a key puts the new key and then removes the old one, and a failure between the two leaves both rather than neither.
+Keys are 1 to 128 characters with no `aws:` prefix and no duplicates, and values up to 256.
+Without `onPut` and `onRemove` it is read-only, as for a system image or an AWS-managed policy.
+Panels use the per-service wrappers in `src/components/resource-tags.tsx` and the writers in `src/mutations/tags.ts` rather than wiring the calls themselves.

 - **Form.** The fields come in the order AWS asks for them. Settings that are on or off are `Switch`es, and a multi-select picker (subnets, security groups) is a `SwitchList`, a boxed list with one switch per row. Checkboxes only select table rows.

+- **CLI.** Every create form ends with a `CliCommandPanel` showing the AWS CLI commands that send the same request, built from the form's live values and only the flags the console actually sends. The commands wrap to the panel's width and never scroll sideways; Copy takes the unwrapped text.
+- **Sections.** Related fields are grouped in `PanelSection` boxes, as the instance launch form groups Image, Instance, Network and Root volume.
+- **Nothing to pick, no field.** An optional picker with nothing usable to choose, such as Launch Template or Placement Group with none available, is left out of the form rather than shown holding only `none`.
+- **Advanced settings.** Settings most users leave at their defaults sit in a collapsed Advanced settings section, which opens by itself when a field inside it fails validation.
+- **Choices with a mark.** A few named products, such as database engines or distributions, are `ChoiceTile`s with the product's own mark from `src/assets/`, not a select. One that cannot be used stays visible and disabled, saying why.
+- **Durations and windows.** A duration is a select of presets with the AWS default first and named (`Auto (5 min)` for a record's TTL), keeping a custom value the API returned. A time window, such as an RDS backup or maintenance window, is a day, start time and length picker that refuses an overlap before submitting.
+- **Labels by type.** Where one field means different things by type, its label follows the type, as a record's value reads `IPv4 address` for A and `Mail server` for MX.
+- **Long pickers.** A `SwitchList` that can run long, such as security groups, scrolls inside its box rather than pushing the form down.
+- **Help.** A field's longer explanation goes in an (i) beside its label, through the `info` prop of `TextField` and `SelectField`, rather than in text under the field. Text under a field is for what the user must know before submitting.
+- **Submit.** `FormActions` cross-fades the submit label into a spinner with its pending label over 150ms, at one width, so the button never changes size, and `FormLock`, a native `<fieldset disabled>`, disables every control above it until the request settles. Nothing above the form appears or moves, and the panel does not scroll.
 - **Failure.** A refused request shows beside the button through `FormActions`'s `error`, and the form unlocks. The handler wraps only the mutation call in `try`, with an empty `catch` that returns, because react-hook-form rethrows whatever the handler throws and the error is already on screen from the mutation's state.
 - **Success.** `onClose(id)` closes the panel and selects the new resource, where the list has a panel to select it in.

It masks firewalld wherever it is installed, since the Spinifex nftables policy is the only supported node firewall. It writes a needrestart drop-in so an apt upgrade never restarts the Spinifex, OVS or OVN units; restarting them after an upgrade is left to the operator. An unset `--firewall` keeps the mode recorded in `/etc/spinifex/firewall/mode`, and otherwise arms the policy when firewalld was active. Where systemd-resolved is installed but not running, resolvconf is absent and NetworkManager runs, it hands host DNS to resolved: it saves `/etc/resolv.conf` once to `/var/lib/spinifex-reset/resolv.conf.orig`, links `/etc/resolv.conf` to the resolved stub, and stops unless resolved has upstream servers and the package repository host still resolves. It links `/usr/bin/spx` to `/usr/local/bin/spx` where sudo's PATH leaves out `/usr/local/bin`, and takes the nbdkit plugin directory from `nbdkit --dump-config`, stopping when nbdkit cannot say. `SETUP_STAGES` runs a subset; `ISO_BUILD=1` runs it inside the ISO builder's chroot. |

A rerun after that handover adds a missing drop-in, reloads NetworkManager and relinks the stub.

 | `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. It runs OVS and OVN as root, setting `OVS_USER_ID` and `OVN_USER_ID` where `/etc/sysconfig` holds them, and hooks the socket-permission helper onto `ovs-vswitchd`, `ovn-controller`, `openvswitch-ipsec` and, on EL, `ovn-northd`. `--management` also starts the OVN central services, writes their `ovn-ctl` flags to `/etc/default/ovn-central` (Debian) or `/etc/sysconfig/ovn-northd` (EL), and records the role in `/etc/spinifex/ovn-role`. With clustered databases it returns only once this node's NB and SB members are back in their RAFT clusters under a known leader, and fails after `OVN_RAFT_REJOIN_WAIT` seconds (default 60) otherwise, so reruns one node at a time never take two members of a cluster down. A later run without `--management` refuses while that file, or the `OVN_CTL_OPTS` line older nodes carry in `/etc/default/ovn-central`, records the role. It adds `maxsize 100M` to the OVS and OVN logrotate files, plus `rotate 5` where the file sets no count, and rotates as root, matching the daemons. On a host whose IPsec stack is libreswan it enables, stops and masks `openvswitch-ipsec.service` and `ipsec.service` for the daemon to unmask when IPsec is on, unless `openvswitch-ipsec.service` is already running; elsewhere it enables and starts `openvswitch-ipsec.service`, unless the daemon has masked it to keep IPsec off. The links it creates persist through systemd-networkd where that is enabled, and otherwise through `/etc/spinifex/hostnet.json`, which `spinifex-hostnet.service` (`spx admin hostnet apply`) replays at boot and on every OVS start, starting `ovn-controller` again when an OVS stop took it down; the first run records the choice in `/etc/spinifex/hostnet-backend`. Where NetworkManager runs, it leaves the links Spinifex owns unmanaged. |
 | `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. Before touching any host it refuses hosts of different OS families (`distro_os_family`) or `spx` versions, and `--ipsec on` when any host uses libreswan. The scripted form of [install-multi-node](../docs/install/install-multi-node/README.md). 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. |
