Bryn Mailer f6f3956952 feat: enable viperblock at-rest encryption by default on fresh installs (#323)
* feat: enable viperblock at-rest encryption by default on fresh installs

Fresh installs left nodes.<node>.viperblock.encryption_key_file empty, which
viperblockd treats as legacy cleartext mode. The encryption machinery existed
but the install path never generated a key or set the field.

Provision a cluster-wide viperblock master key in all three fresh-install
flows and render its path into spinifex.toml:

- admin init (single node): generate the key locally.
- admin init --multi-node (leader): generate once, save locally, and
  distribute via the formation server (mirrors IAM master key distribution).
- admin join (joiner): receive the shared key from the leader rather than
  minting its own, so volumes sealed on any node open everywhere. Lenient on
  absence — an older leader returns no key, so the joiner warns and stays
  cleartext instead of failing the join.

The key file is omitted from the template when unset, so upgrades with no
existing key keep running cleartext.

* fix: make viperblock encryption key group-readable for both readers

The key is loaded by two services per node — viperblockd (spinifex-viperblock)
and the awsgw EC2 handlers (spinifex-gw), both in the spinifex group — so it
must be group-readable, not owner-only like the per-node predastore key.

The previous commit generated the key but never registered its path with the
deployment ownership machinery, leaving /etc/spinifex/viperblock as root:root
0700 (non-traversable) and the key as root:root 0600. The daemon failed at
startup with "stat ... permission denied".

Mirror master.key: setup.sh creates /etc/spinifex/viperblock (0750), and
SetServiceOwnership chowns the dir to spinifex-viperblock and promotes the key
to root:spinifex 0640.

* fix: read viperblock config.json through StateBody for encrypted volumes

The metadata layer parsed config.json with json.Unmarshal/NewDecoder directly,
which fails on encrypted volumes/AMIs now that viperblock wraps VBState in a
valid-JSON envelope ({"v":1,"payload":...,"authtag":...}). DescribeImages
silently skipped encrypted AMIs (count=0 → "no AMIs available"), bricking the
whole launch path.

Route every config.json read through viperblock.StateBody, which unwraps the
envelope (no key needed — the metadata is authenticated, not encrypted) and is
a no-op for unencrypted volumes:

- image: DescribeImages, getVolumeConfig, amiNameExists, GetAMIConfig
- volume: getVolumeConfigAndEncryption, and mergeVolumeConfig (so the
  refuse-to-merge-encrypted guard sees the real VBState instead of clobbering
  the envelope with a tag-less blob)
- admin: readAMIConfig, readVolumeConfig

Josh Siviour b23fa3bf60 feat(eks): managed control-plane VPC (Set B) + control-plane lifecycle hardening (#356)
* feat(eks): VM-side managed-addon delivery transport

Stage CreateAddon manifests in KV host-side; the control-plane VM pulls the
staged set through the AWS gateway (signed GET /clusters/{name}/internal-addons/
{accountId}), renders the baked bundles into the K3s auto-deploy dir, and
reports per-addon delivery status on a dedicated eks.addon.*.status channel that
the cluster reconciler CASes onto AWS-visible AddonStatus (CREATING->ACTIVE).

- gateway: ListInternalAddons route + ListStagedAddonManifests NATS action
- handlers: addon status reconciler (nextAddonStatus), staging installer
- eks-node AMI: eks-gateway-fetch binary + mulga-eks-addon-sync agent
- agent renders idempotently (cmp before replace) so K3s auto-deploy does not
  re-apply every tick and clear the Addon CR .status.gvks readiness signal
- agent mirrors per-tick delivery outcomes to the serial console for host-side
  observability

* fix(eks): provision cluster NLB synchronously so the endpoint carries the real front-end IP

The cluster NLB front-end IP is assigned by the async LB-VM launch
(launchLBVMAsync), but EnsureClusterNLB read it back synchronously right after
CreateLoadBalancer returned — losing the race and falling back to the synthetic
<lb>.elb.spinifex.local DNS name. That name is unresolvable (no Route53) and is
not in the apiserver serving-cert SAN, so kubectl against the cluster never
connects.

Split the elbv2 create: the public CreateLoadBalancer stays async (267.4 — an
inline multi-minute VM boot head-of-line-blocks the gateway responder), and a
new CreateLoadBalancerSync drives the data-plane launch inline and returns the
LB carrying its front-end address. The EKS cluster-create worker runs off the
gateway responder, so it uses the sync entry and reads the IP from the return
value instead of racing persisted state. No polling.

- elbv2: factor provisionLBDataPlane out of launchLBVMAsync; add CreateLoadBalancerSync
- eks: ensureClusterLB uses the sync entry, sets FrontendIP from the result,
  drops the read-back; EnsureClusterNLB fails loud (ErrClusterNLBFrontendIPUnavailable)
  when no front-end IP is allocated rather than shipping the DNS-name fallback
- eks: drop the DNS-name endpoint fallback; the endpoint is always the front-end IP

* feat: auto-wire IGW for internet-facing EKS cluster endpoint

An internet-facing cluster NLB allocates an external front-end IP and the
OVN dnat_and_snat for it, but the external switch + localnet + gateway LRP
that make that IP answerable on the wire are built only on IGW attach. The
control-plane NLB is a system instance, so ensure an IGW on cluster build
and reclaim it on teardown.

EnsureClusterIGW (idempotent, reuses a customer IGW untouched) runs before
EnsureClusterNLB when the endpoint is public; DeleteClusterIGW (ownership-
scoped) removes only the cluster-owned IGW in purgeClusterInfra, before the
VPC delete. New IGW dep wired from the daemon.

* fix(eks): tear down infra on failed cluster launch to stop LB EIP leak

A CreateCluster that fails during its background launch flipped the meta
to FAILED but performed no teardown, relying on a later same-name create
to reclaim and purge the infra. EKS cluster names are unique per create,
so that reclaim never fires: the internet-facing load-balancer VM keeps
running with its allocated+associated dnat_and_snat EIP indefinitely.
Over repeated create/delete cycles the EIP pool fills with allocations
bound to terminated instances, so a later allocation's advertised
endpoint and its live OVN NAT diverge onto different pool addresses.

- failClusterLaunch now runs a best-effort purgeClusterInfra on the
  in-memory meta (freshest refs even when the failing step was the meta
  write itself) before MarkClusterFailed. purgeClusterInfra is
  idempotent, so a later reclaim or DeleteCluster re-purge is a no-op;
  the FAILED meta is retained for observability.
- Daemon releaseSystemInstanceEIP extracted and called from both
  TerminateSystemInstance and cleanupFailedSystemInstance, so a launch
  that fails after AssociateAddress releases the eipService allocation
  instead of leaking it (MarkFailed's ReleasePublicIP only knows the
  externalIPAM path).

* feat: EKS managed control-plane VPC (AWS Set B) composed from EC2 APIs

CreateCluster now auto-builds the managed control-plane VPC under the
system account, the spinifex analogue of AWS EKS's hidden managed-account
VPC: a public subnet for the internet-facing NLB, private subnet(s) for the
k3s control-plane VM(s), and a NAT gateway giving the private CP egress for
image pulls. It is composed from the real EC2 VPC-family APIs
(CreateVpc/Subnet, IGW, RouteTable/Route, NatGateway), so per-subnet egress
gating is wired by the existing topology subscribers off the route-table
events those APIs publish — no direct OVN mutation.

This resolves the mulga-siv-292 root cause: the internet-facing NLB and the
private CP were crammed into one customer subnet with no IGW route, so both
were treated as private and dropped by the lr_in_policy 1100 rule, killing
the LB-VM return leg and lb-agent heartbeat. The CP only survived via a
per-instance 1200 reroute bandaid, now removed — the topology expresses
egress instead.

Placement is uniform single/multi-node (CP always in the private subnet).
The system LB VM heartbeats over the mgmt bridge (SystemGatewayURL) rather
than the WAN. Managed-VPC teardown reclaims NAT GW + EIP, route tables,
subnets, IGW, and the VPC in dependency order. Customer subnetIds (Set A /
worker side) remain consumed-not-created and are deferred to the worker
round.

* fix(eks): bake cluster-owner account into CP-VM EKS_ACCOUNT_ID

The managed control-plane VPC (Set B) launches the K3s control-plane VMs and
their ENIs under the system (infra) account, but the on-VM agents — bootstrap
publish, state report, token-review, and add-on fetch — must key on the
cluster-OWNER (customer) account that owns the cluster meta, namespaces, and
AccessEntry KV. Add ClusterAccountID to K3sServerInput and bake it into the
VM's EKS_ACCOUNT_ID, decoupling it from the infra AccountID the VM launches
under. Without this the VM reported state and fetched add-ons against the
system account, so the cluster never observed a healthy control plane (stuck
CREATING, null CA) and kubectl/add-on delivery timed out.

Also refresh the e2e suite doc comment to describe the Set B topology and the
data-plane subtests (kubectl + managed-addon delivery) that now run.

* fix(eks): explicitly delete addon objects on unstage

K3s does not delete the applied resources when an auto-deploy manifest file is
removed from the server manifests dir (documented behaviour). The addon-sync
GC pass relied on that, so after DeleteAddon the rendered manifest was dropped
but its Namespace/ConfigMap stayed standing — the e2e AddonDelivery GC wait
timed out. Copy the manifest aside, drop the original so K3s stops tracking it,
then kubectl delete the objects (--wait=false to avoid finalizer stalls).

Josh Siviour c7f337229f feat(vpcd): drain held DHCP leases on teardown (#346)
DHCP-source external-pool leases are DHCPRELEASEd only on explicit
instance/EIP terminate. Manager.Stop() preserves leases for
adopt-on-reboot, so env teardown/reset kills vpcd and destroys the
per-AZ lease KV without releasing — stranding every live lease
(instance ENIs, EIP allocations, per-VPC LRP gateways) on the upstream
DHCP server until TTL. Across CI churn with fresh client-ids the
upstream scope fills and new launches get no public IP.

Add Manager.DrainAll + a vpc.dhcp.drain RPC and a standalone
'spx admin cluster drain-dhcp' command that releases every held lease.
Wired into both teardown paths (single-node teardown role and
multi-node cluster-teardown.yml) before services stop. Stop() is
unchanged, so normal restarts still adopt leases on reboot.

Josh Siviour 496424c41c test(eks): EKS control-plane E2E suite (Sprint 6g) (#304)
* test(eks): EKS control-plane e2e suite (Phase 1, API-level)

Add tests/e2e/eks/eks_test.go driving the EKS lifecycle against awsgw:
CreateCluster -> ACTIVE (endpoint + CA asserted), kubeconfig artifact
assembly, AccessEntry CRUD, get-token presign decode, DeleteCluster -> gone.

Harness: EKS SDK client on AWSClient + WaitForEKSCluster{Active,Deleted}
pollers. Wire e2e-eks into the Makefile and the single-node CI suite list.

* test(eks): Phase 2 kubectl get-nodes data-plane gate

Add the reachability shim (harness/eks_mgmt.go) that reads the control-plane
VM's br-mgmt IP from the cluster KV meta over NATS, plus a kubectl wrapper
(harness/kubectl.go) that skips when kubectl is absent. KubectlGetNodes points
kubectl at https://<mgmtIP>:6443 (insecure-skip-tls-verify; cert SANs the NLB
DNS, not the mgmt IP) with an aws eks get-token exec block and polls until the
control-plane node is Ready — the get-token webhook auth regression gate.

IRSA pod + the real NLB/Route53 passthrough are deferred to a follow-up.

* test(eks): tolerate doubled NotFound code + dial loopback NATS

DeleteCluster detection matched the SDK constant ResourceNotFoundException,
but awsgw emits ResourceNotFoundExceptionException on the wire — match the
NotFound code by substring so deletion is detected immediately instead of
timing out. The mgmt-IP shim dialed NATS.Host verbatim (0.0.0.0:4222), which
the serving cert does not SAN; rewrite the wildcard bind to loopback.

Validated live: all 6 subtests green, kubectl get nodes shows the
control-plane node Ready via the get-token webhook auth path.

* feat: build system images with libguestfs (no host block devices)

Replace the qemu-nbd + sudo mount + chroot + /dev-bind flow in
build-system-image.sh with libguestfs (virt-customize / virt-resize /
guestfish). Every operation runs in an isolated userspace appliance VM with
its own kernel, so the build touches no host block device, no host mount, and
needs no sudo — removing the failure class that wiped the host's /dev on shared
CI runners (a leaked /dev bind traversed by rm -rf).

Applies to all distros: alpine resizes via guestfish e2fsck+resize2fs, ubuntu
via virt-resize; customization (packages, binaries, files, setup script,
service enable, cache cleanup) is one ordered virt-customize invocation.
LIBGUESTFS_BACKEND=direct (no libvirt on runners).

Wire the eks-node AMI into the single-node e2e job: the runner builds the
device-free raw, ships it to the VM, and the VM imports it (predastore/NATS are
VM-only) so the eks suite's CreateCluster has an AMI to boot.

* feat(eks): bootstrap + state-report via AWS gateway broker

Converge the EKS control-plane → host channel onto the ELBv2 lb-agent model:
the K3s server VM publishes its bootstrap envelopes and periodic state reports
via SigV4-signed HTTPS POST to the AWS gateway, instead of dialing core NATS
directly. A new gateway action (PublishInternal, POST
/clusters/{name}/internal-publish) relays the payload verbatim onto the
existing eks.bus.* / eks.state.* subjects, so the daemon-side subscriber, KV
persistence/encryption, and reconciler are unchanged.

This removes the VM's need to reach NATS at all, so NATS can stay
cluster-internal behind its bind/firewall/mTLS controls — the prior direct
path broke when NATS was not VM-reachable (e2e CreateCluster timeout) and was
DDIL-fragile (fire-and-forget nats pub, no ack/retry).

- gateway/eks: PublishInternal broker + route; closed-set channel/kind validation
- cmd/eks-gateway-publish: one-shot SigV4 publisher (retry-until-ack) baked into
  the eks-node AMI; replaces the nats-cli publisher in k3s-first-boot.sh and
  mulga-eks-state-report.sh
- handlers/eks + daemon: hand the K3s server VM the mgmt-reachable gateway URL +
  system (Predastore) SigV4 creds + gateway CA instead of NATS URL/token/CA;
  new resolveSystemGatewayBaseURL (mgmt-bridge-first)
- eks-node image: build/install eks-gateway-publish, drop nats-cli download

* feat: migrate eks-token-webhook to the AWS gateway broker

The TokenReview webhook dialed core NATS directly (STS verify + AccessEntry
KV read). On a mgmt-only control-plane VM with NATS bound off-subnet that
fails, so the webhook exited at startup, the apiserver token-webhook
kubeconfig was never written, and the apiserver crash-looped — the cluster
never reached ACTIVE.

Converge it onto the same gateway-broker model as bootstrap/state-report and
ELBv2's lb-agent: the webhook SigV4-signs an HTTPS POST {accountId,token} to
/clusters/{name}/token-review, and the gateway runs the verify + lookup
host-side and returns the resolved identity. The VM now speaks no core NATS.

- internal/eksgw: shared on-VM SigV4 client (also adopted by
  eks-gateway-publish).
- handlers/eks/token_review.go: Authenticate decision core (moved from the
  webhook binary) + ResolveTokenReview host-side wiring.
- gateway/eks token-review route + WebhookTokenReview handler.
- webhook: drop NATS, relay via eksgw.Client; broker fault -> 503 (retryable)
  not a silent deny.
- initd: export EKS_GATEWAY_* / EKS_ACCESS_* creds, not SPINIFEX_NATS_*.

* fix: build eks-node helpers with GOFIPS140; cover token-review broker

eks-gateway-publish blank-imports internal/fipsboot, whose init() panics
unless the binary is built with GOFIPS140=v1.0.0. The eks-node AMI build
omitted the flag, so the binary paniced at first boot right after k3s came
up — k3s-first-boot (set -eu) died before publishing the bootstrap token and
the cluster never reached ACTIVE. Build both eks-node helpers with
GOFIPS140=v1.0.0, matching cmd/lb-agent.

Add NATS-backed unit tests for ResolveTokenReview and the WebhookTokenReview
gateway handler (verify responder + account KV) to cover the new broker path.

* fix: export first-boot env so eks-gateway-publish child sees it

k3s-first-boot.sh and mulga-eks-state-report.sh sourced /etc/spinifex-eks/
first-boot.env but never exported the vars, so the eks-gateway-publish child
process inherited an empty environment and exited '--account-id is required'.
The control-plane VM came up healthy but never published its bootstrap
envelopes, so the cluster never reached ACTIVE. Wrap the source in set -a /
set +a so the KEY=value lines export to child processes.

* fix: make awsgw start --host override actually bind

The 'awsgw start --host' override printed 'Overwriting awsgw host' but the
assignment was commented out, so AWSGW always bound the spinifex.toml host
(a specific WAN IP, e.g. 192.168.0.10). A system instance (EKS K3s control
plane, internal LB agent) has a mgmt-only NIC on-link to the br-mgmt IP with
no route to the WAN IP, so its SigV4 POSTs to the gateway were refused and the
cluster never bootstrapped. Honour --host (e2e passes 0.0.0.0:9999) so AWSGW
listens on all interfaces incl. br-mgmt; the serving cert already SANs every
local interface IP, and WAN clients still reach it.

* test(eks): install kubectl on e2e VM so KubectlGetNodes runs

The eks data-plane subtest (TestEKS/KubectlGetNodes) drives the full
aws eks get-token -> kubectl -> apiserver -> token-webhook -> gateway broker
-> STS verify path — the only end-to-end exercise of the token-review broker.
The e2e binaries run on the VM, where kubectl was absent, so
harness.NewKubectl t.Skip'd it and the path went unvalidated. Install a
checksum-verified kubectl (pinned to the k3s server version) on the VM,
gated on e2e-eks.

Josh Siviour 5aaf8c23d2 fix(eks): make aws eks get-token → kubectl auth work end-to-end (Sprint 6f) (#303)
* feat(eks): webhook observability — console log sink + per-request TokenReview decision

* fix(eks): wire token-webhook authenticator into generated k3s apiserver config

The generated /etc/rancher/k3s/config.yaml overrides the AMI-baked
config.yaml.skel, but its kube-apiserver-arg list omitted the
authentication-token-webhook-config-file arg. The running apiserver
therefore never loaded the token webhook, so bearer tokens minted by
'aws eks get-token' 401'd without the webhook ever being invoked.

* fix(eks): echo TokenReview audiences so api-audiences apiserver accepts the principal

With --api-audiences set, kube-apiserver sends spec.audiences in the
TokenReview and discards an authenticated=true response that does not
confirm a matching audience. The webhook returned an empty
status.audiences, so a valid IAM principal surfaced as a 401. Echo the
request's audiences on success.

* fix(eks): pin token-webhook version v1 so apiserver accepts the response

kube-apiserver --authentication-token-webhook-version defaults to
v1beta1, but the eks-token-webhook responds with an
authentication.k8s.io/v1 TokenReview. The apiserver decodes the response
against the expected GVK and rejects the mismatch, surfacing a valid
principal as a 401. Pin v1 to match the webhook.

Josh Siviour f14fb64562 feat(eks): unify eks-server + eks-agent into one eks-node AMI (#288)
* feat(eks): unify eks-server + eks-agent into one eks-node AMI

Collapse the two K3s AMIs into a single spinifex-eks-node image whose role
(server vs agent) is chosen per-instance at first boot, halving build time,
storage, and CVE-rotation surface.

- scripts/images/eks-node/: superset manifest + merged setup.sh; all role
  services baked but only crond + the new eks-node-role selector enabled.
- eks-node-role first-boot selector reads SPINIFEX_K3S_ROLE, rc-update adds +
  starts the matching services (server: k3s + eks-token-webhook + k3s-first-boot
  publisher; agent: k3s-agent), records /etc/spinifex-eks/role, self-disables.
  Paths are env-overridable; eks-node-role_test.sh covers all five cases.
- mulga-eks-etcd-snapshot.sh early-exits on agent nodes.
- k3s_server_vm.go seeds SPINIFEX_K3S_ROLE=server into first-boot.env.
- Makefile/dev-install: build-eks-node-image / import-eks-node-image replace
  the server+agent targets.
- Delete scripts/images/eks-server + eks-agent. The launcher resolves the AMI
  by the spinifex:managed-by=eks tag, so running clusters (which hold the
  resolved AMI ID) are unaffected.

AMI bake + cluster boot are operational integration steps, not yet run.

* fix(eks): order eks-node-role after cloud-config/cloud-final

The first-boot role selector reads /etc/spinifex-eks/first-boot.env, which
cloud-init delivers via write_files in the cloud-config/cloud-final stages.
The selector only depended on net+cgroups, so on a fast boot it could start
before write_files landed and read a missing role env. Add an after-ordering
on cloud-config + cloud-final so the env file is always present first.

Josh Siviour bfacca7789 feat(eks): 6c token webhook + AccessEntry (IAM auth → kubectl) (#284)
* feat(eks): 6c AccessEntry CRUD + access-policy association

Replace the nine notImpl() AccessEntry/AccessPolicy stubs with real
KV-backed handlers (Q9, API auth mode):

- AccessEntry CRUD persisted at clusters/{name}/access-entries/{hash};
  the principal ARN is hashed into the key (ARNs carry ':', illegal in
  NATS KV keys) while the record keeps the plaintext ARN.
- AssociateAccessPolicy/Disassociate/ListAssociated against the four
  supported AWS-managed policies; unsupported policy ARN or bad access
  scope -> InvalidParameterValue.
- ListAccessPolicies returns the static supported catalogue.
- Cluster-existence gate -> ResourceNotFoundException; duplicate create
  -> ResourceInUseException; node-type entries rejected until 6d.

Updates the daemon routing test for the now-implemented handlers.

* feat(eks): plumb caller principal ARN + bootstrap-creator-admin

Thread the caller's resolved IAM principal ARN from the gateway to the
EKS control plane via a new X-Principal-ARN NATS header, so CreateCluster
can mint the bootstrapClusterCreatorAdminPermissions AccessEntry (Q9):

- utils.NATSRequest takes optional extra headers; PrincipalARNHeader +
  PrincipalARNFromMsg added.
- Gateway resolves the caller ARN best-effort (buildCallerARN) and passes
  it down the EKS route table; only CreateCluster consumes it.
- CreateCluster signature gains callerPrincipalARN; default-true bootstrap
  flag mints a system:masters entry keyed by the caller's exact ARN (the
  token webhook resolves the same ARN from STS). '' degrades gracefully.
- Dedicated daemon handler reads both headers.

* feat(eks): IAM token webhook + STS verify-over-NATS + apiserver wiring

The eks-token-webhook (baked into the eks-server AMI) authenticates kubectl
requests that present an `aws eks get-token` bearer token: decode the presigned
STS GetCallerIdentity URL, verify it, resolve the principal ARN to its cluster
AccessEntry, and answer the apiserver TokenReview with the mapped username +
groups.

STS is hosted in-process in the awsgw service and is not otherwise on the bus,
so awsgw now serves an `eks.VerifyToken` NATS subject that wraps
VerifyPresignedGetCallerIdentity (the cluster name is forwarded so STS enforces
the x-k8s-aws-id anti-replay pin). The webhook reads the AccessEntry KV directly
over its own NATS connection.

Apiserver wiring: the k3s config skeleton sets
authentication-token-webhook-config-file; the webhook writes its own self-signed
serving cert + the apiserver kubeconfig at startup (ordered `before k3s`, with a
bounded wait in the k3s start_pre so the apiserver never loads a missing file).

* fix(eks): omit empty spec from token webhook TokenReview response

* fix(sts): presigned GetCallerIdentity must hash empty body, not UNSIGNED-PAYLOAD

VerifyPresignedGetCallerIdentity built the SigV4 canonical request with
"UNSIGNED-PAYLOAD" as the payload hash. That is an S3-only convention; botocore
and the aws-sdk presign non-S3 requests (sts:GetCallerIdentity, the shape `aws
eks get-token` produces) with the SHA256 of the empty string. Every real
get-token therefore failed signature verification with InvalidIdentityToken,
breaking the entire EKS IAM token-auth flow end to end.

Use the empty-string SHA256. The existing hand-rolled presign tests masked the
bug by signing with the same wrong constant; they now sign correctly, and a new
test presigns with the real aws-sdk-go v4 signer (the same canonicalisation the
CLI uses) so this can't regress silently.

Verified live: a real `aws eks get-token --cluster-name dev1` now resolves to
the caller principal over the awsgw eks.VerifyToken surface; an otherwise-valid
token presented for a different cluster is still rejected (anti-replay intact).

* fix(eks): match access-entry routes on escaped path so slashed principal ARNs resolve

IAM principal ARNs (user/admin, role/foo) embed a '/' that the AWS CLI
percent-encodes in the request path. The dispatcher matched r.URL.Path
(decoded), so %2F became a literal '/' and split the ARN across the
([^/]+) capture, dropping every describe/update/delete-access-entry and
associate/disassociate/list-access-policy call to InvalidActionException.

Match r.URL.EscapedPath() so the encoded ARN stays one segment, then
url.PathUnescape each captured param before it reaches the handler.

Josh Siviour bbff004b45 feat(eks): 6b create-cluster → ACTIVE (single-node SQLite + mgmt-IP NLB stop-gap) (#280)
* feat(eks): cluster_state KV helpers — ClusterMeta + status CAS + prefix sweep

Stage 1 of Sprint 6b CreateCluster lifecycle. Introduces the first
read/write helpers against the eks-account-{accountID} bucket so later
stages (oidc keypair, NLB wiring, cluster reconciler) can persist state
without re-inventing CAS/sweep logic.

- ClusterMeta struct holds the DescribeCluster source of truth (status,
  endpoint, OIDC issuer, CA, VPC config, control-plane VM + ENI, NLB ARN).
- ClusterStatus enum mirrors the AWS EKS string set verbatim.
- PutClusterMeta is unconditional (CreateCluster path); GetClusterMeta
  returns ErrClusterNotFound on key absence so the service boundary can
  map to ResourceNotFoundException.
- SetClusterStatus is revision-checked with bounded CAS retries so the
  reconciler and CreateCluster body cannot wedge each other.
- DeleteClusterPrefix sweeps every clusters/{name}/* key; called from
  DeleteCluster after the OIDC private key is zeroized.

Tests cover round-trip, missing/corrupt blob, idempotent status set,
DELETING transition from every prior state, concurrent revision bump
recovery, sibling-cluster preservation, empty-bucket no-op.

Plan: docs/development/feature/eks-6b-create-cluster.md

* feat(eks): per-cluster ECDSA-P256 OIDC keypair generation + zeroize

Stage 2 of Sprint 6b. Lays the at-rest primitives the CreateCluster body
will call before launching the K3s server VM. Pure crypto helpers — no
daemon, no launcher, no NATS bus.

- GenerateClusterOIDCKeypair mints an ECDSA-P256 keypair per cluster
  (matches eks-v1.md Q8), PEM-marshals the private as PKCS8,
  envelope-encrypts it via handlers_iam.EncryptSecret (AES-256-GCM,
  AwsGW masterKey), writes the ciphertext to OIDCSigningKeyKey, and
  publishes the public JWKS document to OIDCJWKSKey. Returns the JWKS
  bytes so CreateCluster can hand them straight to user-data without
  a follow-up KV read.
- JWKS shape mirrors what handlers_sts.JWKS already decodes for IRSA
  verification (RFC 7517 EC P-256, kid = base64url SHA-256 of SPKI DER,
  alg ES256, use sig). Types are defined locally to avoid a
  handlers_eks → handlers_sts → handlers_eks import cycle; JSON wire
  compat is the contract.
- LoadClusterOIDCPrivateKey is the recovery-path read for future
  stages (reconciler restart, restore-snapshot tooling). Validates
  PKCS8 parses to an ECDSA P-256 *PrivateKey and rejects anything else.
- ZeroizeClusterOIDCKey overwrites the encrypted blob with zeros of
  the same length, then deletes. DeleteCluster calls this *first* so a
  crash mid-teardown leaves no recoverable key material. Idempotent
  on missing key — supports retry semantics.

Tests cover JWKS shape (RFC 7517 EC P-256 with 32-byte SEC1
coordinates), per-cluster key uniqueness, round-trip private-key
decrypt matches JWKS public, wrong-master-key fails, missing-key
ErrClusterNotFound mapping, zeroize idempotency, JWKS survives
zeroize (carries no secret material), padCoord left-pad correctness.

* feat(eks): cluster SG + NLB ensure/delete helpers

Stage 3 of Sprint 6b CreateCluster lifecycle. Adds the customer-account
SG provisioning + per-cluster NLB plumbing the CreateCluster body will
call between OIDC keypair (Stage 2) and K3s VM launch (Stage 4). Pure
interface-call helpers — no daemon, no KV, no NATS bus.

- EnsureClusterSGs creates (or returns) eks-cluster-{name}-control-plane-sg
  and eks-cluster-{name}-nodegroup-sg in the customer VPC, tagged
  spinifex:managed-by=eks + spinifex:eks-cluster=<name> + spinifex:eks-role.
  Idempotent on group-name + vpc-id pair. DeleteClusterSGs is best-effort
  with continue-on-error sweep.
- EnsureClusterNLB provisions the eks-<name> NLB (internal scheme), the
  eks-<name>-cp target group (TCP, port 6443, target-type ip per eks-v1.md
  Q13), and the TCP :443 forward listener. Returns ClusterNLB
  {LoadBalancerArn, TargetGroupArn, ListenerArn, DNSName} so CreateCluster
  can persist every ARN in ClusterMeta. Idempotent on cluster name;
  resource-name length validated against the AWS 32-char cap so a too-long
  cluster name fails with a clear error instead of a generic
  InvalidParameterValue downstream.
- RegisterClusterTarget + DeregisterClusterTarget bind the K3s server VM
  ENI IP to the TG on :6443. Stage 4 calls Register once the VM has its
  ENI IP; DeleteCluster calls Deregister before VM termination.
- DeleteClusterNLB tears down NLB + TG. DeleteLoadBalancer already
  cascades listener cleanup inside the ELBv2 impl. LB sweep error takes
  precedence so DeleteCluster surfaces the more visible failure first
  while the TG sweep still runs.

Narrow sgProvisioner + nlbProvisioner interfaces in-package give tests
hand-rolled recorder fakes; the production VPCService + ELBv2Service
satisfy them structurally so no adapter is needed at Stage 6 wire-up.

Tests cover fresh-creates with right names/tags/ports, idempotent reuse,
mixed-existence (control-plane exists, nodegroup created), name-too-long
rejection, empty-inputs rejection, missing-resource no-op on delete, and
first-error-surfaced sweep continuation on delete.

* feat(ec2): RunInstances honors pre-created NetworkInterfaceId

Closes the AWS-parity gap where RunInstances always auto-created a
primary ENI even when the caller specified
NetworkInterfaces[0].NetworkInterfaceId. The EKS Sprint 6b CreateCluster
launcher (Stage 4) needs to pre-create the K3s server VM's ENI so the
ENI can be tagged/owned distinctly from the launcher's instance; the
existing path silently created a second ENI and left the caller's
unattached.

Changes:
- ENICreator interface gains GetENI(accountID, eniID) → *ENIInfo. ENIInfo
  is a translated struct (SubnetID, VpcID, PrivateIp, MAC, Status,
  SecurityGroupIDs) so handlers/ec2/instance stays free of an import on
  handlers/ec2/vpc.ENIRecord.
- daemon/vpc_adapter.go gains daemonENICreator.GetENI translating
  VPCServiceImpl.GetENIRecord into ENIInfo.
- PrepareRunInstances inspects NetworkInterfaces[0].NetworkInterfaceId
  after the existing subnet/SG lift block. If non-empty, the loop
  dispatches to a new attachPreCreatedENI helper:
    - Looks up the ENI under accountID.
    - Rejects with InvalidNetworkInterface.InUse if Status == "in-use".
    - Calls AttachENI to mark the ENI in-use and bind it to the new VM.
    - Populates instance.ENIId / ENIMac and ec2.Instance network fields
      (PrivateIp, SubnetId, VpcId, SecurityGroups, NetworkInterfaces[0]).
    - Skips the auto-create + public-IP-auto-assign paths; the caller is
      expected to manage public IP out-of-band.
- Auto-create path is left untouched for every other code path: callers
  that pass SubnetId without a NetworkInterfaceId still get a fresh ENI
  with the existing semantics.

Tests cover the four shapes: happy path (auto-create not called, attach
called once, instance populated), in-use ENI rejected with the canonical
AWS error code, lookup error surfaces verbatim, attach error surfaces
verbatim.

* feat(eks): K3s control-plane VM launcher with cloud-init user-data

LaunchK3sServerVM resolves the eks-server AMI by name, pre-creates the
customer-account control-plane ENI in the supplied subnet with the
control-plane SG, renders cloud-init user-data (first-boot env, OIDC
private key, K3s config.yaml with tls-san + service-account args), then
calls RunInstances with NetworkInterfaces[0].NetworkInterfaceId pointing
at the pre-created ENI. RunInstances failures roll back the ENI so the
caller does not leak a customer-account resource.

TerminateK3sServerVM tears the instance and ENI down for DeleteCluster;
missing identifiers are a no-op so retries stay safe.

ENI + VM both live in the customer account (deviation from plan §7 which
specified a SystemAccount-owned VM); cross-account ENI attach is deferred
to a follow-up bead.

* feat(eks): NATS bootstrap subscriber + cluster reconciler + leader lease

NATSBootstrap subscribes to the four single-shot subjects the K3s server VM
publishes (k3s-bootstrap-token, k3s-admin-kubeconfig, k3s-oidc-jwks, k3s-ca)
on eks.bus.{accountID}.{clusterName}.{kind}. Token and admin kubeconfig are
envelope-encrypted via handlers_iam.EncryptSecret and persisted to KV. The
published JWKS is cross-checked against the controller-generated keypair by
kid and rejected on mismatch. The CA lands on meta.CertificateAuthorityB64
via the new SetClusterCertificateAuthority CAS updater.

ClusterReconciler holds a leader lease on spinifex-eks-leader/{accountID}/
{clusterName} (60s TTL, 20s refresh) and drives:
  - CREATING -> ACTIVE once the four bootstrap KV artifacts are present and
    NLB /healthz responds 200.
  - ACTIVE -> probe /healthz on the configured interval, warn on failure.
  - DELETING / FAILED -> exit (DeleteCluster body owns teardown).
Loss of the leader lease (CAS conflict or different holderID) returns
ErrReconcilerLeaseLost so the caller can re-acquire from another node.

Tested with embedded JetStream + a stub HTTPDoer; race-clean.

* feat(eks): OIDC issuer URL builder + reconciler registry

ClusterOIDCIssuer renders the {gatewayBaseURL}/oidc/eks/{region}/{accountID}/
{clusterName} URL kube-apiserver advertises as service-account-issuer and
that STS / external IRSA validators dereference. Validates URL safety on the
path segments so a hostile cluster name cannot inject scheme/path fragments.

ReconcilerRegistry tracks per-(accountID, clusterName) reconciler goroutines
with idempotent Spawn (drop duplicate spawn calls), Stop (cancel one + wait
for release), and StopAll (graceful daemon shutdown). RunClusterReconciler
is the production SpawnReconcilerFn: constructs a ClusterReconciler,
acquires the leader lease, runs Run in a goroutine. Both helpers consumed
by the upcoming service_impl CreateCluster body.

* feat(eks): CreateCluster/DescribeCluster/ListClusters/DeleteCluster bodies

Wires the EKSServiceImpl orchestration deps (VPC SG/K3s/Subnet, NLB,
Instance launcher, AMI resolver, master key, gateway base URL, region,
holder ID, reconciler registry) and implements the four lifecycle
methods:

- CreateCluster: validate → CREATING meta → SGs → NLB → OIDC issuer +
  keypair → K3s server VM (cloud-init carries OIDC private PEM) →
  register ENI IP with NLB target group → spawn NATS bootstrap
  subscriber + per-cluster reconciler via the registry.
- DescribeCluster: KV meta read → eks.Cluster shape, with
  ErrClusterNotFound translated to ResourceNotFoundException at the
  service boundary.
- ListClusters: KV key-prefix scan + sorted maxResults/nextToken
  pagination.
- DeleteCluster: SetClusterStatus DELETING → zeroize OIDC key → stop
  reconciler via registry → deregister NLB target + delete NLB →
  terminate K3s VM → delete SGs → delete cluster KV prefix.

Daemon wiring:

- buildEKSServiceDeps loads MasterKey from BaseDir/config/master.key
  best-effort, resolves the gateway base URL via the same precedence the
  LB-agent block applies later, and passes VPCService + ELBv2Service +
  ImageService directly while adapting InstanceServiceImpl via
  daemonEKSInstanceLauncher (RunInstances passes through; Terminate-
  Instances loops vmMgr.Get + StopOrTerminateInstance in-process).
- SubnetVPCResolver is satisfied by daemonEKSSubnetResolver wrapping
  VPCService.GetSubnet.
- Startup spawns reconcilers for every persisted CREATING/ACTIVE cluster
  via SpawnRegisteredReconcilers; shutdown calls eksService.Shutdown so
  every per-cluster goroutine releases its lease before exit.

Test surface:

- service_impl_test: TestEKSServiceImpl_ClusterLifecycleShimMode covers
  the four lifecycle methods when constructed via the back-compat shim
  (CreateCluster/DeleteCluster → ServerInternal, DescribeCluster →
  ResourceNotFound on empty bucket, ListClusters → empty list).
- daemon_handlers_eks_test: drop the four lifecycle subjects from the
  NotImplemented routing loop; handler-side coverage now lives in
  handlers/eks.
- awserrors: add ResourceNotFound (404) for the DescribeCluster path.

* fix(eks): load master.key from config dir not service data dir

eks_deps read master.key from {BaseDir}/config/master.key, but the daemon
systemd unit sets SPINIFEX_BASE_DIR=/var/lib/spinifex/spinifex (a per-service
data dir). admin init writes master.key to the shared config dir, so the
daemon looked in a path that only resolved when a {BaseDir}/config symlink
existed — awsgw has one, the daemon's nested data dir does not. Result:
MasterKey=nil, depsReadyForOrchestration() false, CreateCluster/DeleteCluster
collapse to ServerInternal.

master.key is a config artifact written next to spinifex.toml. Read it from
filepath.Dir(d.configPath), matching how the daemon already resolves
predastore.toml and TLS certs. No symlink or provisioning change needed.

* fix(eks): register + resolve eks-server AMI via tag, add import --ami-name

CreateCluster's K3s launch failed 'eks: AMI eks-server not found' on every
clean install. Two defects:

1. spx admin images import had no way to name a locally-built appliance AMI:
   --name is a catalog lookup (rejects non-catalog values) and the AMI name
   was hardcoded to ami-{distro}-{version}-{arch}. build-system-image.sh ran
   'import --name $AMI_NAME' for eks-server/eks-agent/GPU images, which all
   failed 'Image name not found in available images'.

2. The launcher resolved DescribeImages by name=='eks-server', a name the
   pipeline could never produce.

Add --ami-name to override the registered AMI name on --file imports (fixes
eks-server, eks-agent, and GPU appliance imports). Resolve the EKS AMI by the
spinifex:managed-by=eks tag the pipeline already stamps, newest-wins on
multiple matches. Tag-based resolution survives the planned server+agent →
single EKS AMI unify untouched (role chosen per-instance at launch).

build-system-image.sh now passes --ami-name; Makefile gains
import-eks-server-image (IMPORT=1) and dev-install.sh imports the AMI when
DEV_INSTALL_EKS=1.

* fix(eks): give K3s server VM NATS token + CA so bootstrap can publish

The K3s control-plane VM was launched with NATSURL=ConnectedUrl() (loopback,
unreachable from the VM) and no auth material, while spinifex NATS requires a
shared token over TLS. The VM could not connect to NATS, so it never published
its four one-shot bootstrap messages and the cluster stayed in CREATING.

Hand the VM the daemon's shared NATS token + CA PEM and a VM-reachable NATS URL
(mirrors the ELBv2 LB-agent shared-credential pattern; spinifex has no nkeys
hierarchy to scope per-principal creds against).

- K3sServerInput: drop dead NATSCredsContent; add NATSToken + NATSCACert,
  required by validateK3sServerInput. user-data writes SPINIFEX_NATS_TOKEN,
  SPINIFEX_NATS_CA + the CA file; first-boot.env tightened to 0600.
- EKSServiceDeps + CreateCluster: pass NATSURL/NATSToken/NATSCACert.
- buildEKSServiceDeps: read CA from config.NATS.CACert; extract
  resolveGatewayHost(); add resolveNATSURL() (same reachable host, NATS port).
- k3s-first-boot.sh: build nats CLI args with --token + --tlsca.

* fix(eks): retry transient bootstrap persists, fail cluster on permanent error

The NATS bootstrap subscriber tore down on the first persist error and the
cluster sat in CREATING forever. Core-NATS delivers a publication once, so a
transient KV blip during persist was unrecoverable and a malformed payload
(bad JWKS kid, non-base64 CA, empty envelope) silently stranded the cluster.

- persistWithRetry rides out transient persist failures in-handler (3 attempts,
  200ms backoff) instead of unsubscribing and waiting for a re-publish that
  never comes.
- errBootstrapPermanent classifies validation failures (malformed envelope,
  empty fields, JWKS kid mismatch, non-base64 CA) as non-retryable so they
  return immediately.
- spawnBootstrap marks the cluster FAILED (with reason) when Run exits with a
  non-context error, so DescribeCluster surfaces the cause and DeleteCluster
  can reclaim resources.
- MarkClusterFailed transitions to FAILED+StatusReason only from CREATING, so a
  late bootstrap error cannot clobber a concurrent delete or healthy cluster.
- casUpdateMeta extracts the revision-checked RMW loop shared by the meta
  setters.

* fix(eks): resume NATS bootstrap for CREATING clusters on daemon restart

SpawnRegisteredReconcilers re-spawned only the reconciler on boot, never the
bootstrap subscriber. A daemon restart while a cluster was CREATING (K3s VM
still booting) lost the subscriptions; the VM published its four one-shot
core-NATS messages to nobody and the cluster hung in CREATING forever.

- BootstrapPendingKinds reports which artifacts (token, kubeconfig, CA) are
  still missing from KV. JWKS is excluded: it persists no artifact and
  re-waiting on a once-published subject would deadlock — its cross-check is
  best-effort across a restart.
- RunForKinds subscribes to a subject subset (nil = all four); Run delegates to
  it. subjectHandlers maps each kind to its handler and rejects unknown kinds.
- SpawnRegisteredReconcilers resumes bootstrap for CREATING clusters, waiting
  only on the missing artifacts, so a mid-CREATING restart still drives the
  cluster to ACTIVE.

* fix(eks): DeleteCluster must not wipe KV or report success on teardown failure

DeleteCluster ran zeroize, NLB teardown, and VM termination as warn-and-continue
then unconditionally swept the per-cluster KV prefix and returned success. A
failed NLB or VM teardown leaked billable resources with no owning record (the
meta holding their ARNs/IDs was erased) and told the operator the cluster was
gone. Zeroize — a stated security guarantee of no recoverable key material —
had its failure ignored too.

- Zeroize, NLB delete, and VM terminate are now blocking: their failures
  accumulate (errors.Join) and abort the call before the KV sweep, leaving the
  cluster DELETING and returning the error so a retry can still reach the ARNs.
- KV prefix sweep runs only after NLB + VM teardown confirm.
- SG cleanup stays best-effort (plan step 5) — a leaked SG strands no owning
  record — and target deregister stays best-effort since DeleteClusterNLB tears
  down the whole NLB + target group.

* fix(eks): persist NLB + control-plane ARNs mid-CreateCluster so failures don't leak

CreateCluster set meta.NLBArn / target-group / instance / ENI in memory and
persisted them only in the final PutClusterMeta, after LaunchK3sServerVM. Any
failure between EnsureClusterNLB and that persist left the NLB + target group +
listener + backing LB VM created but unrecorded; markFailed did no rollback and
DeleteCluster keys teardown off the persisted ARNs, so the resources leaked.

- Persist meta immediately after EnsureClusterNLB (records NLB/TG ARNs) and
  again after LaunchK3sServerVM (records instance + ENI), before the next
  fallible step.
- A failed create now leaves a FAILED meta carrying the resource references, so
  the DeleteCluster teardown path (165.9) reclaims every NLB/TG/listener/VM.
- Tests: NLB-arn-persisted-before-later-failure, failed-create-then-delete
  reclaims NLB, and a CreateCluster happy path. Shared eksServiceFixture
  extracted from the delete-cluster fixture.

* fix(sts): parse path-based EKS OIDC issuer so IRSA accepts 6b cluster tokens

ParseEKSIssuerURL required an `oidc.eks.` host prefix and an exactly-2-segment
path (AWS hosted-EKS shape), but ClusterOIDCIssuer emits — and awsgw serves —
https://{gateway-host}/oidc/eks/{region}/{accountID}/{clusterName}. Every 6b
cluster's iss claim was rejected with "issuer host must start with oidc.eks",
so AssumeRoleWithWebIdentity would fail all IRSA tokens once 6e serves them.

Reconcile on the path-based shape, which is what is actually reachable on
bare-metal/on-prem (no oidc.eks.* vhost or DNS exists). Host trust comes from
the IAM OIDC-provider registration (the full issuer string is the registry key)
and the JWKS signature check, not a host pattern — so the parser drops the host
prefix rule and instead pins accountID/clusterName at fixed positions in a
strict 5-segment /oidc/eks/{region}/{accountID}/{clusterName} path. A crafted
iss with extra or missing segments still fails closed.

Adds a cross-component round-trip test asserting a ClusterOIDCIssuer-built iss
parses back to the same (accountID, clusterName).

* fix(eks): reclaim FAILED clusters on retry + cluster-scoped exists/not-found errors

A failed CreateCluster left a FAILED ClusterMeta that poisoned retries: the
preflight returned ErrorELBv2TargetGroupInUse ("The target group is currently
in use...") for a cluster-exists condition, and because that maps to a
retryable code the SDK's auto-retry surfaced ResourceInUseException instead of
the original failure. FAILED clusters were also a dead state — visible to
neither a clean recreate nor a clear lifecycle.

- Add EKS-specific ResourceInUseException / ResourceNotFoundException codes with
  cluster-scoped messages; CreateCluster's exists check and DescribeCluster /
  DeleteCluster not-found now use them instead of the ELBv2 / EC2 codes.
- CreateCluster reclaims a FAILED cluster: it purges the prior attempt's
  recorded resources and clears KV before recreating, so a retry (including the
  SDK auto-retry) is idempotent rather than blocked. Teardown failure surfaces
  rather than recreating on top of orphans.
- Extract purgeClusterInfra, shared by DeleteCluster and the reclaim path
  (blocking zeroize/NLB/VM, best-effort SG, KV sweep only after teardown
  confirms).
- FAILED clusters remain observable via Describe (status=FAILED) and List — no
  state where create blocks but describe/list show nothing.

* fix(eks): fail CREATING clusters that exceed create timeout

A per-cluster reconciler that never observes a ready control plane (bootstrap
artifacts missing or healthz unreachable) previously stayed CREATING forever.
Add a configurable create timeout (default 15m): once meta.CreatedAt is older
than the deadline and the cluster is still not ready, the reconciler marks it
FAILED with a reason, exiting the loop. Within the deadline it stays CREATING.

* fix(eks): surface ACTIVE cluster health in describe-cluster

The reconciler only slog.Warn'd a failing /healthz probe for an ACTIVE
cluster, so describe-cluster kept reporting a dead control plane as healthy.
Add HealthIssue + LastHealthProbe to ClusterMeta, write them from the ACTIVE
reconcile branch (recording the failure reason, clearing on recovery), and map
a non-empty HealthIssue to a ClusterHealth ClusterUnreachable issue in
describe-cluster.

* test(eks): add plan-mandated CreateCluster/DeleteCluster service cases

service_impl_test only covered shim mode. Add the four cases the plan's Testing
section requires: CONFIG_MAP auth mode rejected (and API accepted), missing
subnetIds rejected, DescribeCluster 404 with full deps wired (past the shim
short-circuit), and the DeleteCluster zeroize-before-teardown ordering proven
by forcing a teardown failure and asserting the OIDC key is already wiped.

* refactor(eks): return OIDC private-key PEM from generator, drop re-read

CreateCluster discarded GenerateClusterOIDCKeypair's return then did a second
KV get + AES-GCM decrypt via loadOIDCPrivateKeyPEM to re-derive the same PEM the
generator already had in hand. Return the plaintext PEM (alongside the JWKS)
from the generator and use it directly; remove loadOIDCPrivateKeyPEM and the now
-unused crypto/x509 + encoding/pem imports in service_impl.

* fix(eks): make CreateCluster/DeleteCluster failures diagnosable

Unmet orchestration deps and a missing eks-server AMI both collapsed to a bare
ServerInternal with no request-time log, leaving the client a 'contact AWS
re:Post' message and zero cause. Enumerate the specific missing deps and log
them at ERROR, returning ServiceUnavailable (an operator/config fault, not an
unrecoverable internal one). Add an ErrEKSServerAMINotFound sentinel so a
missing control-plane AMI is logged and surfaced as ServiceUnavailable too.

* fix(eks): serialize REST-JSON responses via jsonutil so the AWS SDK can parse them

WriteJSONResponse marshaled aws-sdk-go *Output structs with encoding/json,
which ignores their locationName tags and emits Go PascalCase keys. EKS
clients parse restjson on the lowercase locationName, so every field of
list/describe/create/delete responses was silently dropped (empty endpoint,
null identity.oidc.issuer). Marshal via jsonutil.BuildJSON — the same
marshaler the SDK uses for restjson bodies — which honors locationName.

Adds wire-shape tests asserting lowercase keys present and PascalCase absent.

* feat(eks): launch K3s server VM via boot-agnostic system-instance path

The EKS K3s control-plane VM launched through the plain tenant RunInstances
path, so it had only its VPC ENI and no management-bridge NIC -- no route to
the daemon's NATS endpoint. It never published its bootstrap subjects and the
cluster stayed CREATING.

Generalize LaunchSystemInstance to a boot-agnostic contract supporting both
system-instance boot styles:

  - BootDirect: direct-boot microVM (fw_cfg blobs) -- ELBv2 LB agent
  - BootAMI:    AMI boot + cloud-init seed (q35)    -- EKS K3s server VM

The launch contract moves to a neutral handlers/sysinstance package so EKS can
launch system VMs without an eks->elbv2 dependency; handlers/elbv2 re-exports
the types as aliases. The BootAMI branch mirrors the daemon's
Prepare -> Insert -> Launch split and allocates the mgmt NIC on the VM record
between Insert and Launch, so the cloud-init network-config renders a static
mgmt0 interface. The EKS NATSURL is now sourced from the mgmt-bridge IP (the
on-link address the VM's mgmt NIC can reach), falling back to the gateway-host
resolution when no mgmt bridge exists.

Verified: K3s VM now boots from the eks-server AMI under q35 with a mgmt0 NIC
(10.15.8.x), reachable from the host over br-mgmt, with NATS on-link at the
bridge IP. No AMI rebuild required.

* fix(eks): make DeleteCluster K3s teardown idempotent so it can't wedge

TerminateK3sServerVM treated every DeleteNetworkInterface error -- and every
TerminateSystemInstance error -- as blocking. Because instance terminate is
async, the immediate ENI delete races it: the first attempt fails
InvalidNetworkInterface.InUse, and once the instance-terminate cascade releases
the ENI every retry fails InvalidNetworkInterfaceID.NotFound. Both joined into
purgeClusterInfra's teardownErrs gate, which short-circuits before the SG sweep
and KV prefix delete -- so once the ENI was gone the cluster was stuck DELETING
permanently, leaking its control-plane + nodegroup SGs and KV meta.

Classify the teardown errors instead of blanket-propagating:

  - ENI InvalidNetworkInterfaceID.NotFound / InvalidNetworkInterface.NotFound
    -> idempotent success (the cascade or a prior retry already deleted it);
    must not block the downstream SG + KV sweep.
  - ENI InvalidNetworkInterface.InUse (VM still terminating) and any other
    error -> retryable; surfaced so the cluster stays DELETING and the
    reconciler retries once the instance releases the ENI.
  - Instance already gone -> idempotent. TerminateSystemInstance now returns a
    sysinstance.ErrSystemInstanceNotFound sentinel that the EKS path tolerates
    via errors.Is, so a retried delete after the VM drained completes.

Add awserrors.IsErrorCode(err, code) as the shared delete-error classifier
(substring match through %w wrapping) and route the lone ad-hoc strings.Contains
guard in daemon/vm_adapters.go through it.

Verified: delete-cluster on three clusters left wedged DELETING / FAILED (ENI +
VM already gone) all complete -- clusters erased, SGs + ENIs reclaimed, no leak.

* fix(eks): gate ACTIVE on verified JWKS cross-check, not pre-seeded key

The controller pre-seeds OIDCJWKSKey at create time, so its presence
proved nothing about the running cluster's actual signing key. A cluster
could reach ACTIVE — and start signing IRSA tokens — before the K3s VM's
published JWKS was ever cross-checked against the generated keypair.

Add an OIDCJWKSVerifiedKey marker written by persistJWKS only after
assertJWKSMatch passes. The reconciler's ACTIVE gate and
BootstrapPendingKinds now key off the marker, not the pre-seeded JWKS.
assertJWKSMatch is map-based and also rejects kty mismatch.

* fix(eks): collapse duplicated gateway-host switch into resolveGatewayHost

startCluster reimplemented the 5-case gateway-host precedence inline,
duplicating resolveGatewayHost (used by the OIDC issuer and EKS NATS URL).
If one drifted, the OIDC issuer host embedded in cluster tokens would
diverge from the host LB VMs use to reach the daemon -> IRSA iss mismatch
and cluster-wide token rejection.

startCluster now calls resolveGatewayHost and derives the multi-node
mgmt host route (mgmtRouteVia) from the resolved host. resolveGatewayHost
carries the canonical case enumeration; a table test pins all five
branches plus the case-1 skip guards and the no-host fallthrough.

* fix(eks): make eks-server VM boot diagnosable + fix first-boot publisher crash

Three issues found while diagnosing why K3s clusters never leave CREATING:

1. setup.sh: the stock Alpine cloud image lists `console=tty0` LAST in
   default_kernel_opts, so Linux binds /dev/console to the framebuffer and the
   host-side serial capture sees only kernel dmesg — OpenRC, cloud-init, and
   k3s-first-boot output were invisible. Reorder so console=ttyS0 is last.

2. k3s-first-boot.initd: command_background was "no" while output_log/error_log
   were set; start-stop-daemon rejects --stdout/--stderr without --background
   ("Failed to start k3s-first-boot"), so the bootstrap publisher never ran and
   the cluster wedged in CREATING. Background it (the publisher waits up to 5min
   on K3s /healthz and must not block the runlevel anyway) and route its output
   to the serial console, which the orchestrator captures (the VM has no login).

3. k3s-first-boot.sh: on the /healthz timeout, dump the tail of /var/log/k3s.log
   to the console so the apiserver's own failure is visible host-side.

* fix(eks): seed K3s apiserver a public OIDC key, not the private key

buildK3sUserData pointed both kube-apiserver service-account args at the same
private-key file. --service-account-key-file requires a PUBLIC key — k8s
ParsePublicKeysPEM rejects a private-key PEM with "data does not contain any
valid RSA or ECDSA public keys" and the apiserver crash-loops, so K3s never
reaches /healthz, first-boot never publishes, and the cluster wedges in
CREATING.

Add PublicKeyPEMFromPrivate (PKIX public PEM from the PKCS#8 private key) and
seed it to a separate /etc/rancher/k3s/oidc-signing-key.pub.pem. Point
service-account-key-file at the public file; keep service-account-signing-key-file
on the private file. Runtime-verified: the apiserver crash is gone and K3s now
starts and schedules system pods.

* feat(eks): egress-only SNAT + DNS for K3s control-plane VM

The K3s server VM (a hidden system instance) could not pull system-pod
images: it had no internet egress and no working resolver, so
coredns/traefik/metrics-server never started and /healthz timed out.

Egress: give the single control-plane VM egress-only internet, confined
to its /32, with no inbound exposure and no customer-visible resource.

- policy/route.go: SystemInstanceEgressPriority (1200, above the drop
  gate) + AddSystemInstanceEgress/Delete — a reroute scoped to
  ip4.src == <vmIP>/32 so peers in a shared subnet are unaffected.
- policy/nat.go: AddSystemInstanceSNAT/Delete — a plain snat (not
  dnat_and_snat, so no inbound path), idempotent on its pool external IP.
- external/igw.go: L5 EnsureSystemInstanceEgress/Remove resolves the
  gateway nexthop and attaches the reroute + snat (mirrors the NAT-GW
  egress path; ADR-0006 S1/S4/S5 preserved).
- subscribers: vpc.add/delete-system-egress topics + handlers.
- handlers/eks: allocate a hidden (ManagedBy=eks) pool address on
  CreateCluster and publish add; release + publish delete on teardown.
  EIP dep wired through EKSServiceDeps + the daemon.

DNS: the eks-server AMI is Alpine/dhcpcd and /etc/resolv.conf is a
dangling symlink, so DHCP-supplied resolvers are never persisted. Write
a real /etc/resolv.conf from the K3s VM cloud-config via bootcmd (not
write_files — a write_files entry follows the dead symlink, fails, and
aborts the whole block, dropping first-boot.env + the k3s config).

* feat: EKS 6b single-node SQLite pivot + bootstrap-envelope fixes

Switch the K3s server VM from embedded etcd to embedded SQLite (kine)
for the single-node v1, so CreateCluster reaches a healthy control plane.
etcd's per-commit fsync stalls past the apiserver deadline on viperblock's
deferred-durability block path; SQLite tolerates it.

- k3s server: omit cluster-init (selects SQLite/kine), add anonymous-auth=true
  so the reconciler's anonymous /healthz NLB probe returns 200.
- first-boot readiness gate: anonymous /healthz (401 under CIS anonymous-auth
  =false) -> authenticated 'kubectl get --raw /readyz'.
- first-boot publish: emit a JSON BootstrapEnvelope for all four subjects
  (token, admin-kubeconfig, oidc-jwks, ca); jwks and ca were absent before.
- nats pub: --stdin -> --force-stdin (nats CLI 0.4.0).
- manifest: add jq (builds the bootstrap-message JSON envelopes).

* feat: EKS reconciler probes control-plane mgmt IP until DNS lands

The host-side cluster reconciler cannot resolve or route to the VPC-internal
NLB DNS endpoint (no authoritative DNS / Eclipso yet), so CreateCluster timed
out in CREATING and was marked FAILED even though the control plane was healthy.

Probe the control-plane VM's br-mgmt NIC address directly — the one apiserver
endpoint reachable from the daemon. Capture the mgmt IP from the launch result
(SystemInstanceOutput.MgmtIP -> K3sServerOutput.MgmtIP -> ClusterMeta.
ControlPlaneMgmtIP) and build the reconciler health URL as
https://<mgmtIP>:6443/healthz. The probe client already sets InsecureSkipVerify,
so the mgmt IP need not be in the apiserver cert SAN.

Workaround until authoritative DNS + a host-reachable NLB front-end land, at
which point spawnReconciler reverts to the NLB endpoint.

brynmailer-mdc ef50392f9e feat: wire viperblock at-rest encryption key through daemon and AWS handlers
Adds EncryptionKeyFile to ViperblockConfig (cluster config) and
viperblockd.Config. viperblockd loads the master key once at
launchService start via masterkey.LoadShared and passes
MasterKey + EncryptionEnabled into the VB constructed for every
mounted volume.

AWS handlers (volume.CreateVolume, instance.newViperblock,
image.snapshotStoppedVolume) and the spx admin AMI-import path now
resolve the key via utils.LoadViperblockMasterKey — a process-wide
cache keyed by path so the per-VB lookup is one map hit after the
first load.

volume.mergeVolumeConfig: switch from json.Unmarshal to json.Decoder
so a trailing AES-GCM tag cannot route the body to the wrapper-only
path, and refuse outright when state.EncryptionEnabled — re-marshaling
an encrypted VBState here would strip the tag and brick the volume.

cmd/spinifex viperblock CLI grows a --encryption-key-file flag (env
SPINIFEX_VIPERBLOCK_ENCRYPTION_KEY_FILE) under a distinct viper key
so it does not collide with predastore's identically-named flag.

Josh Siviour 8883984f3f feat(eks): eks-server + eks-agent AMI manifests (#273)
* feat(eks): eks-server + eks-agent AMI manifests + builder INSTALL_FILES

Manifest-driven AMI build for the two EKS image variants (eks-v1.md Q12).
Lifted forward from cs-eks-6b so the K3s boot path can be smoke-tested in
isolation before CreateCluster orchestration lands.

Builder:
- build-system-image.sh gains optional INSTALL_FILES (src:dst pairs,
  mode 0644, parent dirs auto-created). Symmetric with INSTALL_BINARIES.
- ENABLE_SERVICES moves after INSTALL_FILES + SETUP_SCRIPT so init scripts
  the manifest references are on disk before rc-update enables them.

eks-server image (Alpine 3.21.7, q35, 4G):
- K3s v1.32.5+k3s1 (downloaded at bake time, SHA256 verified against the
  upstream sha256sum-amd64.txt trust anchor).
- nats-cli v0.4.0 (not in Alpine main/community — pulled from upstream
  release zip; unzip installed + purged in same setup step).
- OpenRC init scripts: k3s, eks-token-webhook, k3s-first-boot.
- Cron periodics under /etc/periodic/{15min,daily}/ for state-report +
  etcd-snapshot.
- k3s-first-boot publishes node-token + admin kubeconfig over NATS on
  first successful K3s healthz, then self-disables (sentinel + rc-update
  del).
- config.yaml.skel without webhook-token-auth — wiring it before the real
  webhook lands (cs-eks-6c) would block anonymous probes against /healthz.
  Orchestrator drops the live config + restarts k3s.

eks-agent image (Alpine 3.21.7, q35, 2G):
- Same pinned K3s release for server/agent lock-step.
- k3s-agent OpenRC service refuses to start without K3S_URL+K3S_TOKEN —
  fail-closed pre-orchestration.

eks-token-webhook stub (cmd/eks-token-webhook/main.go):
- 503 + Retry-After:30 on every path. Statically linked. Lets the AMI
  build succeed and kube-apiserver boot cleanly. Replaced wholesale by
  cs-eks-6c.

Init system divergence from spec wording: Alpine ships OpenRC, not
systemd. Unit files use .initd extensions and cron periodics instead of
.service / .timer. Bead-level intent (auto-enable on boot, periodic
execution) preserved.

Smoke-tested:
- eks-server: builds 300M qcow2; qemu q35 boot reaches K3s apiserver on
  6443 within ~120s; HTTPS probes return valid k8s Status JSON (the 401
  is K3s v1.32 default RBAC behaviour against anonymous, not a regression).
- eks-agent: builds 280M qcow2; qemu boot mounts root cleanly.

* feat(eks): make targets for eks-server + eks-agent AMI builds

- build-system-image gains subdir-manifest fallback: tries
  scripts/images/$(IMAGE).conf first, then scripts/images/$(IMAGE)/manifest.conf
  so the new EKS layout works alongside the existing flat lb manifest.
- build-eks-server-image / build-eks-agent-image — explicit convenience
  targets that delegate to the generic one.

Josh Siviour f877f5edef feat(network/external): restore source=dhcp on external pools (#262)
* refactor(network/external): introduce Allocator interface + StaticPoolAllocator

Carve external IP allocation out of handlers/ec2/vpc/external_ipam.go into
network/external/static_pool.go behind a typed Allocator interface. The KV
bucket name, schema, CAS retry count, and gateway-IP reservation semantics
are unchanged so existing static-pool data carries over with no manual
migration.

ExternalIPAM stays in handlers/ec2/vpc (L5 cleanup deferred per plan) but
becomes a thin facade that constructs a StaticPoolAllocator and delegates
Allocate / Release / GetPoolRecord through the new interface. Q4 will plug
DHCPPoolAllocator into the same Allocator slot.

Plan: docs/development/improvements/external-pool-dhcp-source.md (Q1).

* feat(network/external/dhcp): package skeleton — Client + Fake + KV store

New network/external/dhcp/ package, restored from the structure deleted
in Slice C (commit 7ff013a) but rehomed under the ADR-0006 layer tree:

- client.go      Client interface + AcquireRequest + Lease (with
                 RenewAt/RebindAt/ExpiresAt helpers).
- nclient4.go    NClient4Client — AF_PACKET DORA / Renew / Release
                 backed by insomniacslk/dhcp/dhcpv4/nclient4.
- fake.go        In-memory test fake with per-step hooks for fault
                 injection and acquire/renew/release call counters.
- kv.go          Store over the per-AZ spinifex-dhcp-leases-<az> KV
                 bucket: Put / Get / Delete / List. Schema matches the
                 plan (absolute timestamps for acquired/t1/t2/expiry).
- *_test.go      Lease-timer arithmetic, fake lifecycle, nclient4 input
                 validation, KV roundtrip + version-key isolation.

Not yet wired into vpcd, ExternalIPAM, or any allocator — Q3/Q4 plug
it in. Plan: docs/development/improvements/external-pool-dhcp-source.md (Q2).

* feat(network/external/dhcp): DHCPManager + daemon-side NATSClient

Adds the per-vpcd DHCPManager that owns active lease state: KV scan on
startup (re-issues RENEW for non-expired entries, drops the rest),
per-lease renewal goroutines with jittered T1/T2/expiry timers and
post-expiry re-DORA, and NATS request/reply subscribers on
vpc.dhcp.acquire / vpc.dhcp.release. Acquire is idempotent on client-id,
coalesced via singleflight so concurrent retries do not produce
duplicate wire DORAs.

Adds the daemon-side dhcp.NATSClient wrapper (RequestAcquire /
RequestRelease) that ExternalIPAM will route DHCP-sourced allocations
through in Q4. Still no allocator wiring — vpcd does not yet construct
the manager.

* feat(network/external/dhcp): wire DHCP allocators; re-allow source=dhcp

Adds DHCPGatewayLRPAllocator and DHCPPoolAllocator, the two consumers
of the Q3 DHCPManager. The gateway-LRP allocator runs in-process inside
vpcd and DORAs once per VPC (client-id `dhcp-gw-lrp-<vpcID>`, used in
centralized NAT). The pool allocator runs daemon-side and routes
per-EIP / ENI / instance acquisitions through vpcd over the restored
vpc.dhcp.acquire / vpc.dhcp.release topics.

ExternalIPAM now dispatches per-pool: static pools keep the existing
StaticPoolAllocator + KV bucket; DHCP-sourced pools attach a
DHCPPoolAllocator via EnableDHCP. vpcd constructs the dhcp.Manager
when any pool has Source="dhcp" and selects the DHCPGatewayLRPAllocator
for IGWManager; everything else keeps StaticRangeAllocator /
LinkLocalAllocator.

Config validator re-allows source="dhcp", requires bind_bridge, and
rejects range_* / gw_lrp_range_* keys on DHCP pools. Unknown sources
are rejected with the supported list. Allocator.Release uses a
server-side IP→client-id lookup so the existing (pool, ip) signature
keeps working for both static and DHCP pools.

Plan: docs/development/improvements/external-pool-dhcp-source.md (Q4)

* feat(spx admin init): restore --external-source=dhcp + --external-bind-bridge

Source defaults to dhcp when --external-pool is omitted; static remains the
default when a pool range is supplied. Adds PoolBindBridge propagation through
ConfigSettings + formation.NetworkConfig + spinifex.toml template so vpcd's
DHCPManager finds the bridge to DORA on across single-node and joiner paths.

* fix(network/external/dhcp): derive chaddr from client-id when HWAddr unset

DHCPGatewayLRPAllocator and DHCPPoolAllocator (first acquire) own no NIC
and pass an empty HWAddr to the manager. nclient4 rejected the request
with "dhcp acquire: hw_addr is required", breaking nightly cells 1/3/8/10
at AttachIGW. Derive the chaddr from the client-id via utils.HashMAC so
the upstream DHCP server sees a stable 02:xx:xx:xx:xx:xx MAC per AWS
identifier, matching the OVN-side MAC scheme operators already grep for.

* fix(network/external/dhcp): enable IFF_PROMISC on bind_bridge across DORA

Nightly cell 1 timed out at OFFER step with "no matching response packet
received". Upstream router replied unicast to the derived 02:xx chaddr
which the Linux bridge had never learned, so the kernel dropped the
frame before nclient4's AF_PACKET socket could see it.

Reference-counted IFF_PROMISC toggle around every Acquire/Renew/Release
so overlapping leases on the same bridge share one flag flip and the
last release restores prior state. Soft-fails to a warn log when
CAP_NET_ADMIN is unavailable — operator may already have promisc set.

* fix(network/external/dhcp): RFC 2131 retransmission — retry DISCOVER 3×

NClient4 was configured with WithRetry(1) + WithTimeout(60s), meaning a
single DISCOVER per Acquire. When the first frame is lost (STP convergence
on a freshly-up bridge, upstream packet loss) the call blocks the full
60s and fails. Nightly cell 1 hit this at startup: gw-lrp Acquire for two
VPCs timed out back-to-back before any e2e step ran.

Switch to WithRetry(3) with a 5s per-attempt seed; nclient4 doubles the
deadline on each retransmission (5s, 10s, 20s) and sends a fresh DISCOVER
each round. Total budget ~35s, three frames on the wire — recoverable
without the higher layer noticing.

* fix(network/external): three CI-blocking extdhcp bugs

DHCP-source pools failed e2e-nightly cells 1/3/8/10 (net: dhcp) after
the restore-dhcp-source branch landed. Three independent root causes:

* gateway nexthop dropped: GatewayIPAllocator.Allocate had no return
  channel for the upstream router learned from lease.Routers. igw fell
  back to link-local 169.254.0.2, unreachable on the WAN subnet, so
  instance egress and SSH-in died silently. Widen the interface to
  return nexthop; DHCP impl pulls Routers[0]; empty Routers is now a
  hard error. Static impl returns pool.Gateway as before.

* DORA budget shrunk 6x: WithTimeout(5s) x WithRetry(3) gave a 15 s
  wallclock for the full DORA, no outer backoff. Restore the deleted
  dhcp_manager.go schedule [4s, 8s, 16s, 32s] under a 90 s budget with
  +/- 1 s per-attempt jitter; drop nclient4Retries to 1 so the leaf
  stays single-shot and the budget arithmetic lives in one place.

* every vpcd subscribed to vpc.dhcp.acquire: plain nc.Subscribe meant
  every vpcd in real-multi cells DORA'd in parallel with the same
  derived chaddr, causing upstream-server NAK / lease leak. Switch to
  QueueSubscribe with per-AZ queue "vpcd-dhcp-workers-<az>".

tomnewton-mulga 78d703da78 Feat/mig capable (#260)
* feat(gpu): add NVIDIA MIG multi-instance GPU support

Partitions MIG-capable GPUs (A100, A30, H100) into isolated slices exposed
as mdev devices instead of whole-GPU VFIO passthrough. VMs attach via
-device vfio-pci,sysfsdev=<mdev-path> using the GPUAttachment discriminated
union (PCIAddress for whole-GPU, MdevPath for MIG).

Key changes:
- gpu: new MIGProfile/MIGInstance types, IsMIGCapable model map, mig.go ops
  (EnableMIGMode, DisableMIGMode, CreateInstances, ListInstances,
  DestroyAllInstances, enrichMdevPaths)
- gpu.Manager: Claim() returns (*GPUDevice, *MIGInstance, error); AddMIGInstances,
  ReclaimByMdev for restart recovery; MarkMIGFailed per-slice
- daemon: buildGPUPool helper partitions devices into whole-GPU vs MIG pools;
  MIGProfile config field selects profile per node or per GPU override
- vm.VM: GPUAttachments []gpu.GPUAttachment replaces GPUPCIAddresses []string
- admin CLI: spx admin gpu mig status/enable/disable subcommands with
  admin.SetMIGProfile for spinifex.toml writes
- docs: COMMANDS.md updated with three new MIG management command rows

* test(gpu): unit tests for MIG parsers and pool manager

Cover all pure parsing functions (parseMIGMemory, isCapacityExhaustedError,
extractProfileFields/GIFields, parseMIGProfiles, parseMIGInstances,
parseCreatedGIID/CIID) with realistic nvidia-smi fixture output.

Manager MIG tests cover AddMIGInstances, Claim/Release on mdev-backed entries,
MarkMIGFailed, ReclaimByMdev, and interaction with whole-GPU MarkFailed — all
using fake mdev directories in t.TempDir() so no GPU hardware is required.

* feat(gpu): dynamic MIG profile-per-request with on-demand GI/CI lifecycle

Replaces static config-driven MIG pre-carving with a dynamic model where
the MIG profile is specified per RunInstances call via mig.<profile>
instance type names (e.g. mig.1g.10gb) that mirror nvidia-smi nomenclature
directly.

- Manager.Claim(instanceID, profileName): fast path claims a pre-carved
  slice; slow path dequeues a free MIG GPU, releases the lock, calls
  nvidia-smi mig -cgi/-cci to carve all slices, then reclaims the lock to
  commit and return the first slice
- Manager.Release: last release on a dynamically-carved GPU calls
  DestroyAllInstances and returns the GPU to freeMIGGPUs, allowing a
  different profile on the next claim
- AddMIGGPU(dev): registers a fresh MIG GPU for dynamic allocation;
  AddMIGInstances (restart recovery) keeps its no-destroy semantics
- GenerateMIGTypes: produces mig.<profile> InstanceTypeInfo entries from
  gpu.ListProfiles at daemon startup; IsMIGType/MIGProfileFromType let
  callers inspect these names
- buildGPUPool: calls ListInstances for recovery, AddMIGGPU for fresh
  GPUs, ListProfiles to collect MIG profile specs for type generation;
  removes setupMIGInstances and migProfileForDevice
- GPUClaimer.Claim gains profileName param; daemonGPUClaimer, service_impl
  call sites, and fakeGPUClaimer all updated

* fix(gpu): correct mdev parent detection and make --profile optional for mig enable

enrichMdevPaths was using os.Readlink on "parent_bus_0" (a non-existent
sysfs attribute) and then on ".." (a directory, not a symlink) — both
would fail on real NVIDIA hardware, breaking CreateInstances and
ListInstances on daemon restart recovery. Fix: read the mdev UUID's own
symlink target, which always encodes the parent GPU's PCI address in its
path (e.g. .../0000:01:00.0/<uuid>).

Make basePath injectable in enrichMdevPaths so the fix is covered by a
new set of unit tests using temp-dir symlinks (TestEnrichMdevPaths_*).

Remove the MarkFlagRequired("profile") from "spx admin gpu mig enable":
Phase 2 is fully dynamic — the daemon carves slices on demand at
RunInstances time. Without --profile, the command just enables MIG mode
and destroys any pre-carved slices so the daemon starts with a free GPU.
With --profile, behaviour is unchanged (pre-carve a static pool).

* chore: writeups for smci and arcee

* test: add coverage for MIG exec, manager slow-path, instancetypes and admin

- Add mig_exec_test.go with fake nvidia-smi harness covering Enable/Disable MIGMode,
  IsMIGModeEnabled, DestroyAllInstances, ListProfiles, CreateInstances, ListInstances
- Extend manager_mig_test.go with slow-path Claim/Release tests using fake nvidia-smi
- Add generate_test.go coverage for IsMIGType, MIGProfileFromType, GenerateMIGTypes
- Add admin_test.go coverage for SetMIGProfile (create, update, idempotent, error paths)
- Make mdevBasePath a var to allow sysfs injection in tests
- Add json tags to GPUAttachment fields to satisfy musttag linter

Diff coverage: 75.6% (threshold: 60%).

* fixed gpu passthrough doc

* Revert "fixed gpu passthrough doc"

Josh Siviour fd3dc6b680 feat(network): ADR-0006 layer redesign + IPsec/OVN hardening (#255)
* refactor(vpcd): remove macvlan bridge mode

Macvlan was a single-NIC SSH-safe hack that predated veth mode and was
never selected by any active config path. Deletion is Phase 0 item 1 of
the network layer redesign (mulga-siv-125.1).

Removed:
- BridgeModeMacvlan const + setMacvlanMAC + ifaceIsMacvlan probe
- Macvlan MAC alignment block in launchService (only fired on dead path)
- Macvlan branch in detectBridgeMode + matching tests
- Macvlan duplicates of IGW/AddNAT centralized-NAT tests (veth versions
  already cover the same path)
- --macvlan flag + macvlan case branch in setup-ovn.sh

Refactored:
- useCentralizedNAT() now == BridgeModeVeth (was != BridgeModeDirect);
  verifyBridgeMode already rejects empty/unknown at startup
- Three IGW-pool tests now explicitly WithBridgeMode(BridgeModeVeth)
  (previously relied on empty-mode defaulting to centralized)

Kept intentionally:
- Deprecation notes in docs/compute/vpc-networking/README.md
- Legacy macvlan-interface cleanup in reset-dev-env.sh + ansible
  teardown role (migration for operator systems with stale spx-ext-*
  interfaces from pre-veth installs)

* feat(vpcd): resolve external CIDR at startup with bounded retry

Block service start until the WAN bridge has an IPv4 address, with a 30s
retry window. Phase 0 item 2 of the network layer redesign
(mulga-siv-125.1). Guards the boot race where vpcd starts before
systemd-networkd finishes DHCP on br-wan, or before netplan applies a
static config.

Skipped when ExternalMode is empty (overlay-only deployments).

Forward-compatible with ADR-0006: the new resolveExternalCIDR /
externalCIDRFromBridge helpers become the backing implementation of
HostWiring.ExternalCIDR() once the network/host package lands in Phase 1.
Until then the resolved value is only used to fail-start on missing
uplink.

* fix(vpcd): cover external CIDR startup paths

Extract launchService's CIDR-resolve block to ensureExternalCIDRReady
helper so it's unit-testable, and add direct tests for
externalCIDRFromBridge (loopback + unknown-interface) to exercise the
original literal body. Closes the diff-coverage gap on Phase 0 commit
15b564d which left these paths unreachable from unit tests.

* refactor(network/ovn): extract L1 OVN client to network/ovn package

Move OVNClient interface, LiveOVNClient, ACLSpec, ErrNATNotFound and
namedUUID helper from services/vpcd to a new spinifex/network/ovn
package. The mock relocates to spinifex/network/ovn/mock as a
sub-package. Storage fields on the mock become exported so vpcd tests
can continue to seed/inspect state across the new package boundary.

services/vpcd retains thin type-alias and var-alias shims so existing
callers compile unchanged; Phase 2 removes those shims as vpcd is torn
down.

Adds -coverpkg=./spinifex/... to test-cover so cross-package test
exercise of mock methods continues to count toward coverage now that
the mock lives outside vpcd.

First sub-step of Phase 1 of docs/development/feature/spinifex-network-redesign.md
(bead mulga-siv-125.2). Pure refactor; no functional change. All
existing tests pass; preflight green.

* feat(network/topology): TopologyManager interface + vpcd adapter

Add spinifex/network/topology with Manager interface, VPC/Subnet/Port
specs, and OVN object naming helpers covering the L2 stable contract
(§7 of the redesign plan). Phase 1 keeps existing in-tree OVN names
(rtr-, ext-port-, sg_) and notes the §7.3 targets for a later
reconciliation migration.

TopologyHandler in services/vpcd grows EnsureVPC / DeleteVPC /
EnsureSubnet / DeleteSubnet / EnsurePort / DeletePort /
SetPortSecurityGroups methods that mirror the corresponding NATS
handlers' OVN ops with Spec inputs instead of nats.Msg envelopes,
satisfying topology.Manager via a compile-time check. Existing handlers
are unchanged; the duplication is short-lived (Phase 2 collapses them).

Smoke tests in topology_manager_test.go cover the idempotent create
path, delete cascade, and declarative SG membership move. Deliverable:
TopologyManager.EnsureVPC/Subnet/Port callable; all existing tests
green.

Second sub-step of Phase 1 of docs/development/feature/spinifex-network-redesign.md
(bead mulga-siv-125.2).

* feat(network/host): L0 HostWiring interface + physical/veth impls

Phase 1 deliverable for mulga-siv-125.2. Introduces network/host (L0 of
ADR-0006): UplinkMode enum, Wiring interface, and Physical/Veth
implementations with injectable Runner + InterfaceReader for testability.
Not yet wired into daemon/vpcd — Phase 2 replaces daemon.SetupComputeNode
and vpcd's resolveExternalCIDR with calls through this package.

* feat(network/policy): L3 SecurityGroup/NAT/Route managers

Introduce network/policy as the data-plane policy layer (ADR-0006 L3).
Three managers, all backed by network/ovn:

- SecurityGroupManager: clear+add ACL replacement on an existing port
  group; port group lifecycle stays with L2 (topology.Manager).
- NATManager: bound to one NATMode at construction (derived from
  host.UplinkMode). Distributed sets logical_port/external_mac on EIP
  dnat_and_snat rules; centralised leaves them unset. Per-EIP, NAT GW,
  and IGW-default SNAT entrypoints; all deletes idempotent.
- RouteManager: AddStaticRoute is read-then-decide so retries no longer
  duplicate rows (closing the long-standing non-idempotency bug in
  vpcd/topology.go's IGW default-route path).

ACL priority constants and infrastructure ACL builders move from
vpcd/{security,acl}.go into policy/acl.go with their semantics preserved
(default-deny 900/800 logged, DHCP-allow 1050, tenant 1000). No vpcd
wiring changes here — additive only; the reconciler (bead .3.2) and
network/external (bead .3.4) will consume these managers.

bead: mulga-siv-125.3.1

* feat(network/external): L5 IGW/EIP/NATGW managers

Pure additive — new package, no topology.Manager changes, no rewiring of
existing vpcd handlers. IGWManager builds the external switch + localnet +
gateway LRP + default route + chassis HA, with a flows barrier callers can
inject (production: ovn-nbctl --wait=hv sync). EIP/NATGW are thin L5
wrappers over policy.NATManager. GatewayIPAllocator interface lets the
DHCP-backed allocator stay in vpcd until the DHCP-mgr removal bead lands;
LinkLocalAllocator + StaticRangeAllocator ship here.

* feat(network/reconcile): L6 intent-actual reconciler replaces 5-pass startup

Build spinifex/spinifex/network/reconcile/ package per Phase 2.2 of the
network layer redesign. Reads desired state from NATS KV filtered by
vpc.AZ (with legacy empty-AZ matches-all rule), scans actual state from
OVN NB DB, diffs and applies with VPC → Subnet → Port → SG → IGW →
EIP/NATGW topological ordering.

Atomic port-group join via CreateLogicalSwitchPortInGroups closes the
racy gap the legacy scanENIPortMembership pass used to revive 30s later.
A 5-minute drift goroutine (leader-gated via JetStream KV CAS) replaces
the old 30s ReconcileSGsLoop.

Adds AZ field to VPCRecord stamped at create time. Empty AZ on pre-Phase
2.2 records matches every local AZ, so no migration pass is required.

Replaces and removes the 5-pass startup sequence in services/vpcd:
  - Reconcile + ReconcileFromKV
  - ReconcileSGsOnce + ReconcileSGsLoop
  - RetrofitAllExternalLocalnetOptions
  - RetrofitAllGatewayPortNetworks

IGW fresh-create continues to flow through the legacy NATS handler path
(handleIGWAttach) so the dhcpManager wiring stays intact until Phase
2.3; the reconciler only rebinds gateway-chassis on existing IGW
topology.

Closes mulga-siv-125.3.2.

* refactor(network/topology): promote live Manager impl to network/topology

Move the topology.Manager implementation out of services/vpcd/topology_manager.go
into network/topology/manager_live.go as a standalone liveManager constructed
via NewLiveManager(ovn.Client, opts...). Inputs that varied per-handler
(DNS server resolution from the external pool) are now passed as functional
options (WithDNSServer).

TopologyHandler still satisfies topology.Manager but its methods delegate
to a cached liveManager. The shim stays until the rest of mulga-siv-129
routes NATS subscribers through topology.Manager directly.

Also exports SubnetGatewayCIDR + FormatDNSServerList from network/topology
so the reconciler in network/reconcile can share helpers with the live
manager (audit pass to follow per plan §6).

Test cases ported one-for-one from services/vpcd/topology_manager_test.go
to network/topology/manager_live_test.go; the vpcd-side test file is
deleted. New WithDNSServer test asserts the option propagates into
DHCPOptions rows.

Refs mulga-siv-129 (Phase 2.6 vpcd subscriber migration, Slice 1 of N).

* refactor(vpcd): collapse SG subscribers onto network/{topology,policy} managers

Phase 2.6 / mulga-siv-129 slice 2. Rewrites the vpc.create-sg /
vpc.update-sg / vpc.delete-sg NATS subscribers in services/vpcd as
thin wrappers over topology.Manager (port group lifecycle) and
policy.SecurityGroupManager (ACL programming). Deletes the ~1000
lines of duplicated ACL builder and provisioning logic — its
authoritative copy lives in network/policy.

Surface additions:

- ovn.ErrPortGroupNotFound sentinel; mock + live GetPortGroup wrap
  not-found via fmt.Errorf("%w: ...") so callers can use errors.Is.
- topology.Manager grows EnsureSGPortGroup / DeleteSGPortGroup
  (resolves the apply.go TODO from §2.1 of the redesign plan).
  liveManager implements them with GetPortGroup-then-Create /
  GetPortGroup-then-Clear+Delete idempotency.

Behaviour delta: the old provisionSG rolled back the OVN port group
on AddACLs failure ("all-or-nothing"). The new path lets the port
group survive and relies on network/reconcile to retry EnsureSG on
its next sweep. The all-or-nothing fail-fast test cases are dropped;
ACL emission semantics are covered by network/policy/sg_test.go.

* refactor(vpcd): migrate VPC/Subnet/ENI subscribers to topology.Manager

Phase 2.6 / mulga-siv-129 slice 3. Rewrites vpc.create / vpc.delete /
vpc.create-subnet / vpc.delete-subnet / vpc.create-port /
vpc.delete-port / vpc.update-port-sgs NATS subscribers as thin
wrappers (≤30 lines each) over topology.Manager. Subscriber bodies
now: parse event → translate to spec → delegate to manager.

Deletes:

- vpcd.subnetGateway (and helpers_test.go + topology_test.go's
  TestSubnetGateway block); parity coverage lives in
  network/topology.TestSubnetGatewayCIDR.
- vpcd.reconcilePortSGs (the live manager already exposes the same
  diff-then-transact via reconcilePortSGs on the L2 side).
- vpcd.TopologyHandler.dnsServer; lmDNSServer (passed via
  topology.WithDNSServer to the live manager) is the live path.

Behaviour delta: handlers now strict-parse PrivateIpAddress /
MacAddress / CidrBlock at the NATS boundary and reject malformed
payloads instead of degrading to "no DHCP options". The reconciler
guarantees that field validity is upheld upstream of the publish.

* refactor(network/reconcile): drive SG port groups via topology.Manager

applySGs now calls topology.Manager.EnsureSGPortGroup /
DeleteSGPortGroupByName instead of reaching directly into the OVN client.
Reconcile.Config gains a Topology field (required); the production caller
in services/vpcd passes the TopologyHandler shim, the reconcile package
tests construct a fresh topology.NewLiveManager bound to the mock OVN
client.

DeleteSGPortGroupByName is added to the topology.Manager interface for the
reconciler's orphan-removal path, which iterates raw OVN port-group names
without a groupID round-trip. The existing DeleteSGPortGroup(groupID)
delegates to it.

Resolves the TODO at apply.go:137 carried over from slice 2 of
mulga-siv-129.

* feat(network/policy): add FlowsBarrier option to NATManager

NATManager.AddEIP needs to block on `ovn-nbctl --wait=hv sync` after
writing the dnat_and_snat row so the NATS reply only returns once every
chassis has the rewrite flow. The legacy vpc.add-nat handler does this at
the tail of handleAddNAT; the manager has lacked it since slice 2.1.

NewNATManager grows a functional-options tail (Option / WithFlowsBarrier).
Defaults to a no-op for tests; production wiring in services/vpcd passes
waitForFlowsHV. AddEIP now invokes the barrier after AddNAT, logging at
warn level on failure to match the legacy handler's _ = waitForFlowsHV()
swallowing semantics.

Pre-work for slice 4 of mulga-siv-129 — without the barrier the NAT EIP
subscriber migration would lose the post-write flow-install gate.

* refactor(vpcd): migrate NAT GW subscribers to policy.NATManager

handleAddNATGateway / handleDeleteNATGateway now decode the NATS event
and delegate to policy.NATManager.{AddNATGateway,DeleteNATGateway}. The
manager carries identical OVN logic — same snat type, same ExternalIDs
(spinifex:vpc_id + spinifex:nat_gateway_id) — so existing
TestTopologyHandler_AddNATGateway / DeleteNATGateway suites stay green.

Lazy-constructed NATManager added on TopologyHandler (natmOnce). Mode is
derived from the bridge mode (veth → centralized, direct → distributed)
and the FlowsBarrier is bound to waitForFlowsHV for parity with the
legacy EIP path's tail barrier (used by the next slice, vpc.add-nat).

Slice 4 of mulga-siv-129, sub-step b.

* refactor(vpcd): migrate EIP NAT subscribers to policy.NATManager

handleAddNAT / handleDeleteNAT now decode the NATS event and delegate to
policy.NATManager.{AddEIP,DeleteEIP}. The behavioural contract is
preserved end-to-end:

- Idempotency-skip on a matching dnat_and_snat row (same VPC + LogicalIP,
  plus MAC + LogicalPort under distributed NAT) moves into AddEIP so
  duplicate vpc.add-nat publishes never tear down the rule the previous
  invocation just installed (mulga-siv-124).
- Stale-rule cleanup across every router stays in AddEIP.
- Post-write waitForFlowsHV barrier is now driven by the manager via the
  FlowsBarrier option wired in services/vpcd (slice 4a).
- DeleteEIP returns nil on ErrNATNotFound, matching the handler's
  fire-and-forget "already absent = success" semantic.

The vpcd "errors" import drops out with the inline error-comparison.

Slice 4 of mulga-siv-129, sub-step c.

* refactor(vpcd): migrate IGW subscribers to external.IGWManager (partial)

handleIGWAttach now branches at decode time:
- Centralised NAT + DHCP-sourced pool keeps using attachIGWLegacy because
  the gateway-LRP IP comes from vpc.dhcp.acquire, and that DHCP client is
  the vpcd-local manager that bead mulga-siv-125.3.3 will retire.
- All other shapes (distributed NAT, static-range pool, no pool)
  delegate to external.IGWManager.AttachIGW. The manager mirrors every
  step the legacy handler ran — external switch + localnet port +
  gateway LRP + switch-side router peer + default route + chassis HA +
  waitForFlowsHV tail barrier — so observable behaviour is unchanged.

handleIGWDetach drops its inline OVN walk entirely; both paths exit
through external.IGWManager.DetachIGW followed by releaseGatewayLRPLease.
The lease release stays in vpcd because the upstream client lives in
services/vpcd/dhcp; calling it after every detach is safe because the
upstream server expires unknown leases on its own.

Lazy-constructed IGWManager added on TopologyHandler (igwmOnce). Pool,
allocator (StaticRangeAllocator), chassis, NAT mode, NAT manager, route
manager, and FlowsBarrier are all derived from the existing
TopologyHandler state.

The DHCP-coupled legacy branch retains its full inline OVN logic; it
will disappear in slice-after-125.3.3 follow-on. Slice 4 of
mulga-siv-129, sub-step d.

* feat(ec2/instance): honor AssociatePublicIpAddress per-NIC override

RunInstances --network-interfaces "AssociatePublicIpAddress=true|false"
was silently ignored, only subnet.MapPublicIpOnLaunch gated public IP
assignment. AWS contract is per-NIC override wins.

Extend TestPrepareRunInstances_PublicIPAutoAssigned to table-driven
3 cases: subnet true no-override, subnet false override true, subnet
true override false.

* refactor(config): drop upstream-DHCP config surface (static WAN pool only)

Hard-error in LoadConfig on legacy keys: [network] external_dhcp,
[nodes.<n>.vpcd] dhcp_bind_bridge, and [[network.external_pools]]
source = "dhcp". Add pool range validation (must fit inside the
gateway/prefix_len CIDR; per-cluster non-overlap).

Strip ExternalDHCP from config.NetworkConfig + formation.NetworkConfig
+ admin.ConfigSettings, and DhcpBindBridge from config.VPCDConfig +
admin.ConfigSettings + vpcd.Config. vpcd.ExternalPoolConfig.IsDHCP()
short-circuits to false; the field and downstream DHCP branches in
external_ipam / topology.go remain for Slice C to delete together with
dhcp_manager.

cmd/spinifex/cmd/admin.go: drop useExternalDHCP path and the
detectedDhcpBindBridge helper; require --external-pool when
--external-mode=pool; auto-detect default no longer infers source=dhcp.

service.go's wan_bridge legacy-key rejection now advises removing the
key entirely (vpcd auto-detects br-wan), not renaming to
dhcp_bind_bridge.

Two topology_test cases that exercise the DHCP gateway-LRP path are
skipped — Slice C deletes attachIGWLegacy and these tests together.

* refactor(vpcd): delete dhcp_manager + DHCP gateway-LRP path (Slice C)

Removes upstream-DHCP-client gateway-LRP allocation in favor of static
WAN-pool allocation (StaticRangeAllocator). Part of bead mulga-siv-125.3.3.

- delete services/vpcd/dhcp_manager.go + dhcp/ subpackage (~865 lines)
- delete allocateGatewayLRPIPViaDHCP + releaseGatewayLRPLease paths
- drop ExternalPoolConfig.Source + DhcpBindBridge + IsDHCP() fields
- drop ExternalIPAllocation lease fields (Expiry/ServerID/HWAddr) and
  ExternalIPAMRecord.Source
- drop NewExternalIPAM nc *nats.Conn argument; update all 4 call sites
- rename verifyBridgeMode local dhcpBindBridge -> wanBridge; update error
  strings and tests

Slice D (delete attachIGWLegacy + dispatcher) intentionally deferred.

* refactor(vpcd): delete attachIGWLegacy + IsDHCP stub (Slice D)

Closes mulga-siv-129 slice 4d. Part of bead mulga-siv-125.3.3.

handleIGWAttach now unconditionally delegates to external.IGWManager.
attachIGWLegacy (~207 lines, ~5 OVN write steps + chassis scheduling)
deleted along with its dispatcher branch in handleIGWAttach. The
ExternalPoolConfig.IsDHCP() dead stub is gone.

No code paths or NATS subjects regress: the static-pool / distributed
branches were already going through external.IGWManager since Slice 4d
(6719dc3).

* feat(ipam): Purpose field on every IPAM record (Slice B)

Part of bead mulga-siv-125.3.3.

Adds a Purpose enum (handlers/ec2/vpc/purpose.go) tagging every IP
allocation with its semantic role (eni-primary, eni-public, eip,
igw-lrp, natgw-external, …) so multi-VPC clusters can reclaim/audit
by (owner, purpose).

External IPAM (spinifex-external-ipam, v1→v2):
- ExternalIPAllocation.Type → .Purpose; legacy values mapped via
  LegacyExternalTypeToPurpose (gateway→igw-lrp, auto_assign→eni-public,
  elastic_ip→eip). Unknown legacy values warn and become "unknown".
- AllocateIP / AllocateFromPool / allocateFromPool param rename
  allocType→purpose. All call sites pass Purpose* constants.
- migrate/002_external_ipam_purpose.go: idempotent CAS-retry migration
  with v1/v2-union record shape so partial migrations resume cleanly.

Internal IPAM (spinifex-vpc-ipam, v1→v2):
- IPAMRecord.Allocated []string → []IPEntry{IP, Purpose, OwnerID}.
- AllocateIP gains purpose+ownerID args; ReleaseIP unchanged (still
  keyed on IP).
- AllocatedIPs returns []IPEntry.
- eni.go reorders eniId generation before AllocateIP so the owning
  resource ID lands on the new entry.
- migrate/003_ipam_purpose.go: cross-bucket backfill that reads the
  ENI bucket via the new RunKVWithJetStream path. Orphaned IPs
  (no owning ENI) warn and become Purpose=unknown.

Migrate framework:
- KVContext gains an optional JetStream field; new
  Registry.RunKVWithJetStream method threads it through. RunKV
  signature unchanged — all other callers are unaffected.

Tests:
- ipam_test.go: AllocateIP signature updates; AllocatedIPs now asserts
  IP / Purpose / OwnerID on the returned entries.
- external_ipam_test.go: replaces "auto_assign"/"elastic_ip" literals
  with PurposeENIPublic/PurposeEIP and asserts alloc.Purpose.
- migrate/002 + 003 tests: schema-detect, idempotent rerun,
  no-JetStream fallback, empty bucket.

* refactor(daemon): tombstone obsolete spinifex-dhcp-leases KV bucket

The dhcp_manager removed in Phase 2.3 (bead mulga-siv-125.3.3) owned the
spinifex-dhcp-leases KV bucket. The migrate framework only handles
per-bucket schema version bumps, not bucket deletion, so the obsolete
bucket would linger on upgraded clusters.

Add a one-shot tombstone after initJetStream that deletes the bucket if
present. DeleteKVBucketIfExists treats ErrBucketNotFound and
ErrStreamNotFound as success, so the call is idempotent across restarts.

* feat(config): add network.ipsec_enabled cluster flag (default true)

Add IPSecEnabled to NetworkConfig in both the cluster TOML schema and
the formation handshake payload. Default true so AWS-parity intra-AZ
encryption is on by default. Operators can flip false in
[network] for trusted single-rack lab topologies.

Phase 2.5 (bead mulga-siv-125.3.5) consumes the flag from admin init
(strongSwan provisioning), formation server (propagates to joiners),
and daemon startup (ovs-vsctl ipsec_encapsulation toggle).

* feat(admin): IPsec peer cert generator signed by cluster CA

Add GenerateIPSecPeerCert + IPSecCertPaths in spinifex/admin so admin
init (and the future admin add-node path) can issue per-node IKEv2 peer
credentials signed by the existing cluster CA. The cert carries
id-kp-ipsecIKE (RFC 4945) so strongSwan accepts it as an IKEv2 peer
credential when ovs-monitor-ipsec materialises tunnel configs.

Cluster CA is reused directly — no intermediate strongSwan PKI today;
when intermediate CAs land that becomes a separate workstream.

The cert/key pair lives under {configDir}/ipsec/peer.{pem,key}; the
daemon points OVS Open_vSwitch.other_config (certificate, private_key,
ca_cert) at these paths when network.ipsec_enabled is true.

* feat(admin): wire IPsec peer cert into admin init + join paths

Add --ipsec bool flag (default true) on adminInitCmd. Single-node init
and the multi-node leader path both emit an IPsec peer cert after the
existing CA+server-cert generation. The multi-node formation server
propagates the IPSecEnabled flag to joining nodes via NetworkConfig;
admin join honours it and emits its own peer cert during the same
cert-issuance step that already produces the server cert.

spinifex.toml template gains an unconditional [network] block carrying
ipsec_enabled so the value is visible to operators on every install
regardless of whether external networking is configured. The daemon
reads it via cluster config (NetworkConfig.IPSecEnabled).

Bead mulga-siv-125.3.5.

* build: install openvswitch-ipsec for OVN native IPsec

openvswitch-ipsec provides ovs-monitor-ipsec, which reads the
Open_vSwitch.other_config cert/key/CA pointers and materialises
strongSwan configs for every Geneve tunnel managed by ovn-controller.
Pulls in strongswan + strongswan-pki as transitive deps.

Required by bead mulga-siv-125.3.5.

* feat(daemon): enable OVN native IPsec on intra-AZ Geneve at startup

When network.ipsec_enabled is true (default), the daemon points the
local OVS DB other_config at the per-node IPsec peer cert that admin
init / admin join provisioned (configDir/ipsec/peer.{pem,key} + the
cluster CA at configDir/ca.pem), then sets
other_config:ipsec_encapsulation=true.

ovs-monitor-ipsec (shipped by the openvswitch-ipsec package) consumes
those pointers and materialises strongSwan configs for every Geneve
tunnel ovn-controller programs — including OVN-IC inter-AZ tunnels
when federation lands in Phase 3a.

Missing cert files log a warning and leave Geneve plaintext; operators
upgrading an older cluster reissue certs via spx admin to close the
gap.

Bead mulga-siv-125.3.5.

* test(e2e): multinode IPsec wiring + xfrm SAs + ESP capture

TestMultinodeIPSec asserts:
- OVS DB on every node carries certificate/private_key/ca_cert pointers
  and other_config:ipsec_encapsulation=true (what daemon.enableOVNIPSec
  writes).
- ip xfrm state on every node has at least one AEAD SA in AES-GCM mode
  (rfc4106(gcm(aes)) or gcm(aes)) within 90s.
- tcpdump catches ESP (ip proto 50) on the underlay (best-effort —
  logged only; geneve may be idle during the 5s capture window).

Skips cleanly when the cluster was bootstrapped with --ipsec=false
(no ipsec_encapsulation key on first node).

Read-only over SSH; runs in the parallel bucket alongside the other
non-mutating multinode tests.

* fix(igw): write attachment State="attached" for AWS parity

Reconciler intent loader (network/reconcile/intent.go::loadIGWs) filters
IGW records with `State == "attached"`, but AttachInternetGateway was
writing `State = "available"`. The reconciler therefore never picked up
any attached IGW — `intent_igws=0` on every pass — so the OVN external
switch + gateway LRP + WAN bridge wiring built by IGWManager.AttachIGW
never ran for default-VPC IGWs (whose live `vpc.igw-attach` publish at
daemon bootstrap is lost — vpcd subscriber not yet wired).

Net effect on single-node e2e: every SSH probe to 192.168.x public IPs
timed out (TestSSHProbe, TestModifyInstanceAttribute, TestRebootInstance,
TestNATGateway, TestSGToSGDatapath) because SNAT/DNAT rules on the VPC
router had no path to the external network.

Match AWS InternetGatewayAttachment.State semantics:
 - Attach: State="attached"
 - Detach: State="detached"

Detach value is internal — recordToEC2 gates Attachments on VpcId != "",
so the detached State is never surfaced to API consumers.

Bead: mulga-siv-131

* fix(reconcile): call AttachIGW when IGW topology missing

applyIGWs previously deferred to the NATS handler when an intent IGW
had no external switch in OVN. When the vpc.igw-attach event is lost
(bootstrap-time default-VPC IGW published before vpcd subscriber is
ready), deferral never resolves and VM public-IP traffic dies.

Call IGWManager.AttachIGW directly — it is idempotent (short-circuits
when the external switch already exists), so the reconciler converges
default-VPC IGWs on first pass without duplicating work on subsequent
passes.

Closes mulga-siv-132.

* fix(test): align NewExternalIPAM call with 2-arg signature

Rebase onto dev pulled in daemon_system_instance_test.go which used
the legacy 3-arg NewExternalIPAM(jsNC, js, pools). The feature branch
already narrowed the signature to (js, pools) via the upstream-DHCP
config drop; align the test with the current signature.

* fix(vpcd): EnsureSubnet must EnsureVPC first to avoid NATS race

vpc.create-vpc and vpc.create-subnet are independent NATS events with
no inter-event ordering guarantee. Tenant bootstrap on iam.account.created
publishes both within <1ms, so the subnet handler's
CreateLogicalRouterPort can race the parent VPC's CreateLogicalRouter and
fail with "logical router not found". The cascade fails CreateNetworkInterface
which fails RunInstances which surfaces as InsufficientInstanceCapacity to
the SDK — masking the underlying topology race.

handleSubnetCreate now calls EnsureVPC(VPCID-only) before EnsureSubnet.
EnsureVPC short-circuits on existing LR (idempotent), so the race-winning
vpc.create-vpc handler's full CIDR/VNI ExternalIDs are preserved; if subnet
wins the race the LR is created with bare ExternalIDs (cosmetic) and the
follow-on vpc.create-vpc short-circuits.

Adds TestIntegration_SubnetBeforeVPC regression covering both orderings.

Closes mulga-siv-133.

* feat(ansible): require --external-pool, drop NAT, forward EXTRA_VARS

spx admin init now rejects --external-mode=nat and demands --external-pool
when mode=pool. The ansible init role silently skipped pool flags when the
range was unset, so installs fell over inside the spx validator. Make
targets also swallowed `-e` (make's env-override flag), so operators could
not override pool start/end without editing defaults.yml.

- vars/defaults.yml: rename nat_gateway_ip → external_gateway_ip; add
  spinifex_external_no_external opt-out; document the spx flag contract.
- roles/init/tasks/main.yml: drop NAT branch; assert pool range upfront
  with a fail_msg pointing at EXTRA_VARS / defaults.yml; emit gateway,
  prefix-len, gateway-ip only when explicitly set (let spx auto-detect);
  honour --no-external.
- playbooks/dev-reset.yml: rename captured var; coerce legacy
  external_mode=nat to pool with a warn; tighten gateway regex with \b.
- Makefile: ansible-dev-* targets now forward EXTRA_VARS="key=val ..."
  through --extra-vars so `make` callers can override without editing
  defaults.yml.
- scripts/ansible/README.md: document pool requirement, both invocation
  styles (direct -e vs make EXTRA_VARS), NAT removal.

* fix(ipsec): guard ipsec_encapsulation on ovs-monitor-ipsec liveness

enableOVNIPSec set OVS cert pointers + ipsec_encapsulation=true without
ensuring ovs-monitor-ipsec.service was running. Without that daemon, OVS
holds the cert pointers unused, strongSwan never gets IKE config, and
tunnel traffic ovn-controller marks for encryption gets silently
dropped. TestMultinodeIPSec fails on `node1 xfrm has no AEAD SAs`.

- systemd: spinifex-daemon Wants=/After= ovs-monitor-ipsec.service
- daemon: ensureOVSMonitorIPSecActive — systemctl enable --now +
  is-active poll; refuses to flip ipsec_encapsulation if daemon is dead
- daemon: single-node short-circuit — no peers means no tunnels means
  the flag is at best inert and at worst load-bearing-silent-drop
- ci: capture-net-diag.sh + workflow steps to snapshot OVS/OVN/xfrm
  state on failure, fan out across all 3 multinode nodes

Refs: mulga-siv-136

* test(e2e): sticky-skip downstream SSH tests when probe fails

When TestSSHProbe times out (3 min, typically because of mulga-siv-134
datapath bug), four downstream tests each re-probe SSH on the same
broken datapath and time out identically — single-node job runs ~24 min
instead of ~12 min, with the same error logged five times.

First waitForSSHReady timeout now sets a package-level atomic flag;
subsequent waitForSSHReady / trySSHReady / requireSSHHealthy calls skip
immediately. Preserves the original red signal on TestSSHProbe and on
any test that genuinely needed SSH (Skip ≠ Pass). Bool variant
(trySSHReady) consults but does not set the flag — its caller already
treats False as advisory warning, not fatal.

TestSGToSGDatapath has its own EventuallyErr SSH wait (not via
waitForSSHReady) and needs an explicit requireSSHHealthy(t) gate at
the top of runSGToSGDatapath. TestNATGateway already calls
waitForSSHReady first so the gate fires naturally.

Refs: mulga-siv-137

* fix(ipsec): use Debian unit name openvswitch-ipsec.service

CI artifact shows `Unit ovs-monitor-ipsec.service could not be found`
on every node. Debian's openvswitch-ipsec package ships the unit as
openvswitch-ipsec.service (the binary inside is ovs-monitor-ipsec, but
systemd's name follows the package). The previous commit guarded on
the wrong unit name, so:

- spinifex-daemon.service Wants=/After= silently no-op'd (missing unit)
- enableOVNIPSec's `systemctl enable --now ovs-monitor-ipsec.service`
  failed, daemon logged a warning and continued without flipping
  ipsec_encapsulation=true
- TestMultinodeIPSec skipped with `node1 reports ""` because OVS DB
  never received the cert pointers

Rename across all 5 spots (daemon, systemd unit, test, CI diag script,
workflow journal capture) to match the Debian package layout.

Note: the package itself still must be present on the CI VM image —
that's tracked in the mulga repo (image-builder provision.sh +
bootstrap-install.sh shim).

Refs: mulga-siv-136

* fix(e2e): authorize default SG tcp/22 + icmp in single-node fixture

admin init leaves the default SG closed (AWS parity); the Go single suite
never ported the Phase-5 SG-ingress block that run-e2e.sh has had since day
one, so every test runner SSH/ping probe hits the OVN port-group ACL drop.

- ec2helpers: add AuthorizeICMPIngress + EnsureDefaultSGOpen helpers.
- single/main_test: open default SG once per process in pkgFixOnce.Do.
- witness: extend ensureDefaultSGSSHIngress to authorize ICMP too.
- run-e2e.sh: append matching ICMP authorize next to tcp/22 block.

mulga-siv-134

* fix(network/reconcile): key DHCP_Options lookup by subnet_id not CIDR

Multi-tenant default VPCs share the same subnet CIDR (172.31.0.0/20) per
account. The existing FindDHCPOptionsByCIDR gate at apply.go:107 found
the first account's DHCP_Options row and skipped creation for every
subsequent subnet with the same CIDR. Those subnets' ports then attached
nothing (FindDHCPOptionsByExternalID misses on subnet_id), VMs got no
DHCPv4 lease, and SSH/ICMP into them silently failed even though SG
ACLs and NAT were correct.

Switch the gate to FindDHCPOptionsByExternalID keyed on spinifex:subnet_id
so each subnet owns its own row, matching the attach lookup at line 203.

Verified: account 000000000001 default VPC RunInstances now produces an
LSP with dhcpv4_options populated, VM cloud-init reports a 172.31.0.5/20
lease + default route via 172.31.0.1, and ping + ssh TCP handshake to
the EIP succeed end-to-end. Stale DHCP_Options row for the prior dead
subnet was wiped manually; reconciler recreated the correct row for the
live subnet on its next pass.

* fix(ipsec): enable openvswitch-ipsec at provision time, drop daemon write

Provisioning now runs `systemctl enable --now openvswitch-ipsec.service`
alongside openvswitch-switch and ovn-controller. The spinifex-daemon
process drops its `enable --now` shell-out and only polls is-active.

Sudoers gains one read-only line:
  spinifex-daemon ALL=(root) NOPASSWD: /usr/bin/systemctl is-active openvswitch-ipsec.service

This mirrors the existing vpcd ovn-controller is-active precedent and
removes the daemon's need for systemd-write capability. Aligns with
least-privilege service account pattern: provision enables services,
daemon only reads status.

If the unit is inactive at runtime, the daemon refuses to flip
ipsec_encapsulation=true (silent-drop guard from mulga-siv-136) and
surfaces a clear error pointing at scripts/setup-ovn.sh.

* chore: unblock preflight on feat/network-layer-redesign

Two pre-existing failures blocked preflight on the branch:

- govulncheck flagged golang.org/x/net@v0.54.0 (GO-2026-5026, ASCII Punycode
  rejection bug in idna.ToASCII); reached via utils.DownloadFileWithProgress.
  Bump to v0.55.0; go mod tidy carries x/sys to v0.45.0.
- TestTopologyHandler_SubnetCreate_RouterPortFails asserted subnet create
  fails when the parent VPC router is missing. That contract changed in
  aed7b2e (mulga-siv-133), which made handleSubnetCreate call EnsureVPC
  idempotently before EnsureSubnet to avoid a NATS publish-order race.
  Delete the now-impossible failure case.

* refactor(network/ovn): relocate nbdb model package from services/vpcd

Phase 4 / mulga-siv-125.6 Slice A. Pure import rename, no logic change.

The OVN Northbound DB model (LogicalSwitch, LogicalRouter, DHCPOptions,
etc.) lived under services/vpcd/nbdb/ because that was the original home
of every OVN caller. After Phase 1+2 the L1 client (network/ovn) and all
L3/L5 managers (network/policy, network/external, network/topology,
network/reconcile) became the primary callers — 8 importers in network/*
vs 2 in services/vpcd/. The directory move puts the schema model where
its consumers are, and unblocks deleting services/vpcd/ entirely once
the subscriber/launcher relocations land (Slices B–D).

* refactor(vpcd): delete dead retrofit/reconcileIGW helpers + bridge-mode bleed

Phase 4 / mulga-siv-125.6 Slice B.

Production path no longer touches any of:

- RetrofitAllGatewayPortNetworks / RetrofitAllExternalLocalnetOptions —
  the 5-pass startup leftovers that network/reconcile (Phase 2.2) made
  redundant. Nothing called them outside tests.
- reconcileIGW + its allocateGatewayLRPIP / gwLrpRange helpers + the
  ipv4ToUint32 / uint32ToIPv4 utilities — superseded by
  external.IGWManager (Phase 2.4) which carries its own pool logic.
- ensureLocalnetOptions / ensureGatewayPortNetworks /
  expectedGatewayPortNetwork — read-before-write retrofit shims for the
  same code paths.
- generateMAC — only callers were reconcileIGW + its tests.

useCentralizedNAT (the bridge-mode bleed flagged in plan §2.2) is
replaced by a policy.NATMode value injected via WithNATMode(...). The
mode is resolved once in vpcd.go from host.UplinkMode and threaded into
both the topology-handler lazy managers and the reconciler stack, so
"is this veth?" is no longer a question topology.go can ask. The
TopologyHandler defaults to NATModeDistributed when WithNATMode is
omitted, matching the previous default.

Drops services/vpcd/topology.go from 1220 LOC to 693, deletes ~700 LOC
of obsolete tests (TestGenerateMAC, TestEnsureLocalnetOptions_*,
TestRetrofitAllExternalLocalnetOptions_FixesClearedOptions,
TestReconcileIGW_*, TestGwLrpRange), and frees the nbdb + utils +
net imports in topology.go.

Stale "phase 4 migrates those onto the new managers" comment in vpcd.go
fixed in passing — the subscribers were migrated in Phase 2.6
(mulga-siv-129); only the file-relocation parts of Phase 4 remain.
Stale ensureLocalnetOptions / ensureGatewayPortNetworks references in
network/ovn/{live.go,mock/mock.go} doc comments also cleaned up.

* refactor(network): move NATS VPC subscribers to network/subscribers

Phase 4 Slice C (mulga-siv-125.6). Promotes the NATS event handlers out of
services/vpcd into a new spinifex/network/subscribers package. Subscriber
holds the topology/policy/external managers directly — the lazy *Once
adapter shim (topology_manager.go) is deleted along with vpcd's local
event-struct copies.

launchService now constructs topology.LiveManager eagerly with a DNS
callback derived from external pools (preserving the unscoped-pool lookup
old TopologyHandler.lmDNSServer did), builds every manager up front, then
hands them to subscribers.New + Subscribe. reconcile.New receives
topology.Manager directly instead of through the adapter.

Bridge-mode constants and waitForFlowsHV move into vpcd.go alongside the
launcher; they were left behind as topology.go's last responsibilities.

Handler-layer tests (topology_test.go, security_test.go, integration_test.go)
are dropped: substance is covered by network/topology, network/policy,
network/external manager tests. subscribers/subscribers_test.go adds
focused coverage: missing-dep rejection, topic registration smoke, and
bad-JSON envelope per topic.

services/vpcd is now down to the launcher + the ovn/mock compat aliases
(removed in Slice D when the launcher promotes to cmd/vpcd/).

* refactor(vpcd): relocate services/vpcd → spinifex/vpcd; drop dead aliases

Phase 4 Slice D (mulga-siv-125.6). Final cleanup of the network-redesign
package layout. services/vpcd/ disappears entirely; the launcher remains
an in-process Service impl, just rehomed under spinifex/vpcd/ (no separate
binary — spx vpcd start stays the cobra entrypoint).

- Delete services/vpcd/mock_ovn.go + ovn.go (compat aliases now dead post
  Slice C; only callsite was launchService's NewLiveOVNClient, inlined to
  ovn.NewLiveClient).
- git-rename services/vpcd/vpcd.go + vpcd_test.go to spinifex/vpcd/.
- Retarget three importers (spinifex/service/service.go +
  service_test.go, cmd/spinifex/cmd/service.go) to the new path.
- Fix stale services/vpcd / TopologyHandler comments in network/reconcile/
  + network/external/types.go + spinifex/vpcd/vpcd.go.
- service-interfaces.yaml vpcd path updated.
- Plan doc §13/§14/§16 + §9.2/§19 updated: drop cmd/vpcd/main.go (was
  speculative; never built) in favour of in-process Service impl at
  spinifex/vpcd/vpcd.go. Plan §16 Created list now lists subscribers/.

Phase 4 plan items 1+2 (remove services/vpcd, entrypoint location)
satisfied. Items 3+4 remain blocked on mulga-siv-125.4 + 125.5 (bundled
join token, plan archive).

* fix(ovn): install openvswitch-ipsec + strongswan explicitly

ovs-monitor-ipsec.service fails to start without an IKE daemon. The
openvswitch-ipsec package only Recommends strongswan, so any apt
config that drops Recommends (or a base image with the recommends
already skipped) leaves the service in a Restart loop with 'IKE
daemon is not installed'. Hoist both packages into setup-ovn.sh so
provisioning is the single source of truth — the bootstrap shim in
mulga is no longer needed.

* test(network): pin ADR-0006 invariants to executable suite

Add static-analysis + behavioural tests that bind every safety and
liveness clause in ADR-0006 (S1-S9, L1-L3) to a named Go test. Failure
output quotes the ADR clause verbatim and points at the offending
file:line so future debugging sessions can't quietly bypass a layer
contract to make a test green.

Static-analysis suite (spinifex/network/invariants/):
- S1 layers_test.go: parses `go list -json`; rejects upward layer
  imports and layers pulling from cross-cutter packages
- S2 host_containment_test.go: AST-detects ovs-vsctl / ovn-nbctl /
  ovs-ofctl shell-out outside network/host/
- S3 nat_mode_test.go: rejects .UplinkMode() / NATModeFromUplinkMode()
  calls outside the init-time resolver locations
- S4 names_test.go: AST-detects OVN object name construction (concat,
  fmt.Sprintf, strings.Join) outside topology/names.go
- S5 policy_no_create_test.go: rejects CreateLogical{Switch,Router,...}
  and DeleteLogical{...} calls inside network/policy/
- S6 federation_isolation_test.go: rejects TransitSwitch /
  TransitRouterPort references and ovn-ic literals outside
  network/federation/ (pre-protects the layer before it lands)
- S8 ipsec_test.go: rejects strongswan / xfrm / IKEv2 / libreswan /
  openswan imports anywhere in network/
- S9 reconciler_singleton_test.go: rejects Reconcile…Loop and
  Reconcile…Pass<n> function names anywhere in network/
- S7 nats_subjects_test.go: scans for `vpc.<verb>` subjects missing
  the {azID} segment; calls t.Skip with the gap report so every test
  run prints the work-to-do without breaking CI. Flip to t.Fatalf
  when the cluster-wide subject rename ships.

Behavioural suite (spinifex/network/reconcile/liveness_test.go):
- L1 reconciler converges: scaled-intent (N=1,3,8) double-Reconcile
  property test; asserts second pass is a no-op
- L2 drift bound: structural check that DriftInterval is positive and
  ≤30 min support window; full fake-clock behavioural test deferred
- L3 federation re-enables: t.Skip stub pointing at the missing
  network/federation/ package

Fixes the one production S4 violation the new walker found:
network/external/igw.go was constructing "gw-port-"+vpcID inline.
Adds topology.GatewaySwitchPort(vpcID) helper and retargets both
AttachIGW and DetachIGW callsites through L2.

Plan + per-clause mechanic + phasing in
docs/development/improvements/network-invariants.md.

* fix(ovn): install strongswan-charon (not strongswan metapackage)

The strongswan metapackage's '\''charon-systemd | strongswan-charon'\''
alternative resolves to charon-systemd by default, which ships
/usr/sbin/charon-systemd but not the legacy /usr/sbin/ipsec helper or
/usr/lib/ipsec/charon binary that ovs-monitor-ipsec --ike-daemon=strongswan
shells out to. Install strongswan-charon explicitly to pull
strongswan-starter (legacy ipsec controller) + the matching charon binary,
matching what openvswitch-ipsec.service expects.

Also reset-failed + restart openvswitch-ipsec.service after enable to
recover from the deb post-install starting the service before its
dependencies finished unpacking.

* chore: add CODEOWNERS — joshsiv-mulga gates network/ + vpcd/

Fall-through reviewer for any change is the maintainer.
network/ and vpcd/ are explicitly listed so the matching branch
protection rule ("Require review from Code Owners") routes those
PRs to joshsiv-mulga. Those trees are governed by ADR-0006
invariant tests (spinifex/network/invariants/); CODEOWNERS adds a
human review gate on top of the mechanical fence.

Refs: mulga-siv-141

* chore: CODEOWNERS fallthrough → @mulgadc/mulgadc-engineers team

Fallthrough reviewer should be the team, not a single maintainer, so
any engineer can approve PRs outside the explicitly-gated paths.
network/ and vpcd/ keep joshsiv-mulga as the required reviewer per
ADR-0006 invariant ownership.

Refs: mulga-siv-141

* feat(ci): add test_run workflow input for -test.run filter

Pass an optional regex through to each suite's '\''go test -test.run'\'' so
dispatches can target a single test (e.g. '\''^TestMultinodeIPSec$'\'') without
running the full multinode suite. Threaded through single, multinode, and
reboot suite invocations; empty input preserves current behaviour.

* fix(daemon): flip NB_Global.ipsec=true on management node

Setting Open_vSwitch.other_config:ipsec_encapsulation=true on each
chassis is necessary but not sufficient for OVN native IPsec — without
NB_Global.ipsec=true, ovn-controller never adds options:remote_name to
the Geneve tunnel ports, so ovs-monitor-ipsec sees no IPsec-enabled
tunnels and the kernel xfrm tables stay empty. After enabling
ipsec_encapsulation locally, also write NB_Global.ipsec=true when the
local ovnnb_db socket is present (management node only); workers skip
silently — one writer is enough for a cluster-wide flag.

Adds a scoped sudoers entry pinning the daemon to that exact ovn-nbctl
invocation so the grant can't be reused for other NB mutations.

* fix(ovn): grant charon AppArmor read on /etc/spinifex/ipsec

The strongswan-charon profile only allows reads from /etc/ipsec.*,
/etc/strongswan.*, and a small fixed allowlist. ovs-monitor-ipsec writes
the per-tunnel strongSwan config with absolute paths to our peer cert +
key under /etc/spinifex/ipsec/, so charon hits 'Permission denied'
loading them (it runs as uid 0 but AppArmor still blocks) and no xfrm
SAs come up. Drop a read grant for /etc/spinifex/ipsec/** into the
profile's local override hook + reload.

* fix(ovn): pin OVS system-id to hostname for IPsec cert identity match

ovs-monitor-ipsec uses chassis-id as the IKEv2 `@<name>` peer identity in
the strongSwan config it generates. Our per-node IPsec peer cert
(admin.GenerateIPSecPeerCert) carries the node name as CN + dnsName SAN.
With chassis-id left at the package-generated UUID, charon validates
`@<UUID>` against a cert with dnsName=<hostname> — mismatch returns
AUTHENTICATION_FAILED and no xfrm SAs are negotiated.

Pin system-id to hostname (which equals the node name on Mulga clusters)
by writing both the on-disk source of truth (/etc/openvswitch/system-id.conf,
read by ovs-ctl on boot) and the running OVS DB value. Writing only one
would drift on the next reboot — the original "do not override" comment
was right about that hazard, just wrong about the resolution.

Cross-link the invariant in admin/ipsec.go: changing the cert identity
without updating setup-ovn.sh (or vice versa) breaks IKE silently.

Refs: mulga-siv-136

* fix(ovn): take --node-name flag so chassis-id matches cluster identity

CI hostnames are bead-themed (env20-casuarina) and don't match the
cluster node name (node1/node2) baked into the IPsec peer cert dnsName
SAN at `spx admin init/join --node NAME`. Pinning system-id to
`hostname -s` produced env20-casuarina; charon then validated
`@node1` against dnsName=env20-casuarina and IKE failed with
AUTHENTICATION_FAILED.

Add a --node-name=NAME flag to setup-ovn.sh, default to hostname for
manual/dev invocations, and update the ansible install role to pass
{{ spinifex_node_name }}. The matching bootstrap-install.sh change
lives in mulga.

Refs: mulga-siv-136

* refactor(daemon): relocate L0 helpers to network/host + widen ADR-0006 S2

Phase 4 Slice E of mulga-siv-125.6. Cleans up spinifex/daemon/network.go
per the audit and widens the S2 invariant to forbid OVS/OVN shell-outs
in spinifex/daemon/ (daemon is an L0 consumer; S2 applies).

Moved to network/host/:
- OVSNetworkPlumber + SetupTap/CleanupTap → host.OVSPlumber (host.NewOVSPlumber)
- GetBridgeIPv4 → host.GetBridgeIPv4
- OVNHealthStatus + CheckOVNHealth → host.OVNHealth + host.HealthStatus
- daemon/ipsec.go OVS/OVN ops → host.SetIPSecCertPaths, host.EnableIPSecEncapsulation, host.SetNBGlobalIPSec

Moved to utils:
- sudoCommand → utils.SudoCommand + utils.SetSudoCommandForTest test seam
  (cross-package reassign would trip the reassign linter; helper keeps
  the indirection inside utils).

Moved to vm:
- generateMgmtMAC → vm.GenerateMgmtMAC (pairs with vm.GenerateDevMAC)

Deleted (dead):
- SetupComputeNode (replaced by network/host/bridges.go:ensureBridges +
  scripts/setup-ovn.sh:572-579)
- EnsureDataRoute
- findInterfaceByIP
- daemon/network.go + dead tests in daemon/network_test.go (duplicates of
  vm package tests retained; mgmt MAC test moved to vm/lifecycle_test.go)

S2 invariant (network/invariants/host_containment_test.go) now walks
both spinifex/network/ and spinifex/daemon/, skipping network/host/.

* fix(ovn): broaden AppArmor read grant to /etc/spinifex (covers CA cert)

The earlier override granted reads on /etc/spinifex/ipsec/** only, which
covers the peer cert + key but NOT the cluster CA at /etc/spinifex/ca.pem.
charon then can't load the CA, can't validate the peer cert chain, and
surfaces the failure as `no trusted RSA public key found for '<peer>'`
even though identity matching now succeeds — IKE_AUTH fails with
AUTHENTICATION_FAILED and no xfrm SAs negotiate.

Grant /etc/spinifex/** instead (covers ca.pem + ipsec/peer.{pem,key})
and always rewrite the override so re-runs replace the older narrower
rule.

Refs: mulga-siv-136

* fix(ipsec): symlink cluster CA into charon's default cacerts dir

ovs-monitor-ipsec writes per-conn `cacert=/etc/spinifex/ca.pem` references
in the strongSwan config, but strongSwan 6.0 only loads CAs declared in
standalone `ca` sections or files placed in /etc/ipsec.d/cacerts at
startup. Without this, charon authenticates the local side fine but
rejects every inbound peer cert as `no trusted RSA public key found for
'<peer>'`, AUTH_FAILED, and no xfrm SAs negotiate.

Do the symlink in admin.GenerateIPSecPeerCert (right after writing the
peer cert) — setup-ovn.sh runs before `spx admin init/join` creates
/etc/spinifex/ca.pem, so the wiring can't live there. Use a stage-and-
rename pattern so concurrent test invocations don't race on the symlink.

/etc/ipsec.d/cacerts is on charon's default AppArmor allowlist so no
profile change needed.

Refs: mulga-siv-136

* chore(setup-ovn): drop apt-get install_packages block

OVS/OVN/openvswitch-ipsec/strongswan-charon are baked into the CI gold
image via mulga's image-builder/scripts/provision.sh (commits 116bb05,
a9b3a9c). Keeping a runtime apt-get install path here pulled CI through
apt-cacher-ng on every bootstrap and tripped on intermittent "Message
has been manipulated" InRelease cache corruption (env21/env20 runs).

Drop the install block. Gold-image rebuild is the canonical place to
add new system packages. If a package is missing, downstream ovs/ovn
commands fail loudly during setup-ovn.sh's later steps — clearer signal
than silently re-installing through a flaky proxy.

setup.sh already supports INSTALL_SPINIFEX_SKIP_APT=1 (passed by mulga's
bootstrap-install.sh:237) so this removes the last runtime apt-get call
on the CI provisioning path.

* fix(ovn): gate system-id pin on explicit --node-name

setup-ovn.sh used to fall back to `hostname -s` when --node-name wasn't
passed, and then unconditionally wrote that value to
/etc/openvswitch/system-id.conf + ovs-vsctl external_ids:system-id.

On CI single-node, the gold image already registered a chassis with
name=<UUID>; setup-ovn.sh then rewrote system-id to the bead-themed
hostname (env10-banksia). vpcd's discoverChassis treats any chassis row
whose name != local system-id but hostname == local hostname as a stale
local chassis and skips it, so vpcd reported "no OVN chassis registered
in SBDB" and refused to start, cascading into the e2e + e2e-go failures
on run 26430839508.

Drop the hostname fallback. If --node-name is given, pin both the
on-disk file and the running OVS DB to it (callers that care about
IPsec cert identity matching still get it). If no --node-name is given,
leave the existing system-id alone — that's always safe whether the
value came from a gold-image UUID, bootstrap-install.sh writing nodeN
before this script runs, or a manual ansible value.

* fix(network/reconcile): skip orphan prune on startup; drift owns GC

The vpcd startup reconcile races against the daemon's EnsureDefaultVPC:
the daemon writes SG KV rows + publishes vpc.create-sg on each node in
parallel with vpcd starting up. The leader-gated reconcile can load
intent before any SG row is visible on its local JetStream replica
while subscribers on peer nodes are concurrently creating port groups
from the same vpc.create-sg events. A startup orphan-port-group sweep
then deletes managed sg_* port groups that intent hasn't caught up to.

CI run 26434124790 trace:
  node2 reconcile/lock: elected holder=env20-bottlebrush
  node2 reconcile: starting intent_sgs=0
  node2 reconcile/apply: removed orphan port group pg=sg_161c70ce23e704a2a
  node2 reconcile/apply: removed orphan port group pg=sg_a0d078650a3150391
  node2 reconcile/apply: removed orphan port group pg=sg_54b564b374e9162bb

Every subsequent RunInstances → vpc.create-port failed with
"port group not found" for ~3 minutes until the 5-minute drift tick
recreated the port groups. Tests give up after 60s; six multinode
suites cascade-fail on InsufficientInstanceCapacity.

Split the reconciler into Reconcile (full prune, drift loop) and
ReconcileApplyOnly (no prune, startup). applySGs takes a pruneOrphans
bool. vpcd startup calls ReconcileApplyOnly; drift loop unchanged.
Legitimate orphans get garbage-collected on the next drift tick — at
worst 5 minutes of lingering rows, no production impact.

Add TestReconcile_ApplyOnlyKeepsOrphanPortGroup to lock the contract.

* fix(ipsec): trigger charon rereadcacerts after CA symlink install

strongSwan scans /etc/ipsec.d/cacerts only at charon startup. The unit
openvswitch-ipsec.service is enabled at provision time and starts before
admin init writes the cluster CA symlink, so charon ends up running with
zero CAs loaded. Every IKE_AUTH then fails with `no trusted RSA public
key found for '<peer>'` and no SAs negotiate — the failure mode exposed
by TestMultinodeIPSec.

Append a stroke rereadcacerts call at the end of
installCAIntoCharonTrustStore so an already-running charon picks up the
freshly-placed CA without a service restart. Failure is swallowed at
debug — a missing/stopped charon at admin-init time is expected and a
later startup will scan cacerts naturally.

* refactor(network/host): move IPSec orchestrator from daemon (ADR-0006 S8)

ADR-0006 S8: "IPSec is OVN-native only. No layer implements custom IKEv2,
XFRM rules, or direct strongSwan management. IPSec SA lifecycle is delegated
entirely to OVN native IPSec and is invisible above L0."

The enableOVNIPSec orchestrator and its ensureOVSMonitorIPSecActive helper
lived in daemon/ipsec.go but composed L0 primitives (SetIPSecCertPaths,
EnableIPSecEncapsulation, SetNBGlobalIPSec) that already lived in
network/host. The orchestrator now lives alongside its callees as
host.EnableOVNIPSec, taking configPath and clusterConfig from the daemon at
the call site. Helper and test-override package vars (systemctlActiveTimeout,
ovnNBSocketPath) move with it; tests are translated to call EnableOVNIPSec
directly rather than via the Daemon struct.

Closes mulga-siv-142

* refactor(daemon): use topology.Port for OVN port names (ADR-0006 S4)

ADR-0006 S4 forbids any layer above L2 from constructing OVN object
names. Three daemon sites formatted "port-" + ENIId inline; route them
through topology.Port instead.

Closes mulga-siv-143

* refactor: use topology.Port for OVN port names in handlers + vm (ADR-0006 S4)

Replace inline "port-"+eniID formatting across five sites (eip, instance x2,
vpc/eni, vm/network_helpers) with topology.Port. OVSIfaceID stays as a thin
wrapper to preserve the OVN binding contract comment and existing call sites.

Closes mulga-siv-144

* test(network/invariants): widen scan roots to daemon/handlers/vm/testutil/utils (ADR-0006)

Widen ADR-0006 invariant scan roots so drift in upstack consumers surfaces
in CI. Backlog of violations in widened roots was drained by
mulga-siv-142/-143/-144; this commit makes the wider scan permanent.

  - S2 (host_containment): add vm/ alongside network/ + daemon/
  - S3 (nat_mode):         add daemon/ alongside network/ + vpcd/
  - S4 (names):            add daemon/, handlers/, vm/ alongside
                           network/ + vpcd/; add narrow AWS-ID exemption
                           (vpc-cidr-assoc-) so AWS resource IDs are not
                           misclassified as OVN object names
  - S6 (federation):       add daemon/, handlers/ alongside network/;
                           convert single-root walk to slice
  - S7 (nats_subjects):    add daemon/, handlers/, testutil/, utils/ —
                           stays t.Skip pending cluster-wide subject
                           rename; gap report now lists 58 subjects

CODEOWNERS: add /spinifex/network/invariants/ rule so widening or
narrowing the scan needs explicit owner review.

Closes mulga-siv-145

* chore(e2e): disable IPsec in pseudo multi-node test

Pseudo multi-node runs three simulated nodes as unprivileged tf-user.
The charon trust-store install in 904b45e writes /etc/ipsec.d/cacerts,
which fails with EACCES under a non-root caller and aborts admin init.

Disable --ipsec for this suite — loopback-only nodes don't exercise
real Geneve encryption anyway. Real-multi-node + single-node e2e
(both run admin init via sudo) continue to cover the IPsec path.

* fix(ovn): atomic Ensure* primitives prevent duplicate logical entities

OVN NB has no unique constraint on Name. The previous
GetLogicalRouter→CreateLogicalRouter sequence in EnsureVPC was a TOCTOU
race: when vpc.create on one node and the defensive vpc.create-subnet
EnsureVPC call on another both observed absence, both inserted, yielding
two routers per VPC. The orphan held DNAT references blocking EIP
detach, and DNAT/flow installation landing on the orphan caused
TestMultinodeGuestSSH SSH timeouts.

Add EnsureLogicalRouter / EnsureLogicalSwitch / EnsurePortGroup to the
libovsdb client. Each builds a single OVSDB transaction combining a
wait-op (Until=equal, Rows=[]) gated on absence of a Name match with the
insert. The server serialises the wait+insert atomically; concurrent
callers see exactly one survivor and the rest fall through to a re-fetch
that returns the canonical row.

Switch all production callers (topology.EnsureVPC / EnsureSubnet /
EnsureSGPortGroup, external.AttachIGW, reconcile.applyVPCs /
applySubnets) to the Ensure* variants. Bare Create* remains available to
the L1 wrapper.

Add invariant test TestS4_OVNNamedCreatesUseEnsure (AST walk) to block
future reintroduction of the bare Create* call sites outside
network/ovn.

Mock implements Ensure* under its existing mutex so the concurrency
tests (50/30/30 goroutines for Router/Switch/PortGroup) prove a single
UUID survives.

Refs: mulga-siv-146

* fix(ovn): wait-op rows must be non-empty; flip to NotEqual predicate

The Ensure* primitives sent a wait-op with `Rows: []ovsdb.Row{}` plus
`Until: ==` (RFC 7047 §5.2.6 absence test). The libovsdb Operation
struct tags Rows as `json:"rows,omitempty"`, so the empty slice was
dropped on the wire and ovsdb-server rejected every transaction with
"Required 'rows' member is missing", breaking reconciler bootstrap and
every downstream create-port lookup ("logical switch X not found").

Flip the predicate to the equivalent `Until: !=` formulation with a
single-row projection containing the Name we want absent:

  no row    → projection []           != [{name}] → predicate holds
  row exists → projection [{name}]    == [{name}] → predicate fails

Same atomic guarantee, JSON now well-formed. Mock tests can't catch
this — only a real ovsdb-server validates the envelope.

* chore: remove generateMAC wrapper

* chore: remove all bead / plan references

* fix(network/policy): wait for chassis flows after AddNATGateway

AddEIP fires m.barrier() to block until ovn-northd compiles NB→SB and every
chassis installs the new dnat_and_snat flows; AddNATGateway returned right
after the NB commit. So `aws ec2 create-route … --nat-gateway-id` would
publish vpc.add-nat-gateway, the SNAT row would land in NB, and the API
call would succeed before the gateway chassis had programmed the SNAT flow
for the private subnet.

Phase 8d's 10×5s=50s ping budget races that flow-install latency on slow
CI hosts (last seen run 26455602615 single-node, identical flake on
unmodified dev run 26434711010 — pre-existing, not introduced by Ensure*).

Mirror AddEIP: call m.barrier() after AddNAT returns. Add unit test
TestNATManager_AddNATGateway_FlowsBarrier_Fires covering the new path.

* chore: remove more plan refs

* chore: remove GenerateIPSecPeerCertIfEnabled

* chore: remove dupliate subnetGatewayCIDR function

* chore(network): trim superfluous comments across network/ tree

Collapse multi-paragraph godocs to 1-2 sentences, drop WHAT-restatement
comments, remove section dividers grouping <10 items, and cut prose
narration in tests. ADR clause references, one-line WHY comments for
non-obvious OVN/OVSDB/AWS/NATS semantics, and exported-symbol godoc are
preserved. No behavioural changes.

Packages: invariants, topology, host, external, ovn, reconcile, policy,
subscribers.

* fix(igw): restore attachment State="available" for AWS parity

AWS InternetGatewayAttachment.State is "available" when an IGW is
attached to a VPC, per the AWS SDK doc ("the state is available when
attached to a VPC; otherwise, this value is not returned"). Commit
b7505f8 wrote "attached"/"detached" to align with the reconciler
filter, which inverted AWS parity.

Fix the producer to write "available" again and update the consumer:
 - handlers/ec2/igw: AttachInternetGateway and DetachInternetGateway
   both persist State="available"; IGWRecord comment narrowed.
 - network/reconcile/intent.loadIGWs: filter accepts "available" (was
   "attached"); attachment is identified by VpcId != "".
 - tests updated: igw service_impl_test, routetable service_impl_test
   fixture, reconcile intent_test fixture.

* Update spinifex.toml

* refactor(subscribers): route EIP/NATGW through L5 wrappers (ADR-0006 §S1)

Subscriber previously called policy.NATManager directly for EIP and NAT
Gateway operations, bypassing the L5 wrappers (EIPManager, NATGWManager)
that existed on paper. ADR-0006 §S1 requires every cross-layer call to
pass through the immediate lower neighbor's typed interface; IGW already
followed this pattern.

Wire EIPManager and NATGWManager into the Subscriber struct, construct
them in vpcd alongside IGWManager, and swap the four direct-L3 call
sites (AddEIP, DeleteEIP, AddNATGateway, DeleteNATGateway) onto the
L5 surface (AttachEIP, DetachEIP, AttachNATGateway, DetachNATGateway).
AttachEIP now fires the flows-barrier, giving callers the same
"reachable on return" guarantee IGW already had.

The reconciler still calls policy.NATManager directly; that's a
cross-cutter and a separate concern.

* test(reboot): port 8MB WAL pad workaround from bash run-reboot-e2e.sh

App VMs' user-data writes (unit file + index.html) sit in the on-host
WAL until WriteWALToChunk crosses the 4MB threshold. Host reboot before
that loses them — systemd then refuses to load the zero-byte unit and
the responder never starts. Mirror the bash driver's dd+sync pad so the
WAL flushes pre-reboot. Drop when the upstream WAL fix lands.

* test(e2e): dump OVN/OVS/SG state on Phase 8d NATGW failure

Phase 8d's existing failure path only prints lr-nat-list and
lr-route-list. CI artifacts are not uploaded when run-e2e.sh exits
nonzero, so debugging the NATGW regression requires inline diagnostics
in the journal. Expand the dump to include nb/sb show, chassis bindings,
port_group ACLs, br-int flows filtered to the NATGW IP/private subnet,
host routes, and the private VM's own ip/route/neigh state.

* fix(ovn,reconcile): scope NAT deletes to router; NATGW snat per associated subnet

Two compounding bugs caused Phase 8d NATGW E2E flake (~60% CI failure):

1. ovn.DeleteNAT/DeleteNATByExternalIP searched all NAT rows globally and
   only mutated the named router afterwards. With AWS subnet CIDRs repeating
   across VPCs, (type, logicalIP/externalIP) is not globally unique — the
   delete picked a NAT row owned by a different router, the mutate was a
   no-op, and the row delete failed with "remaining reference(s)", leaving
   the original router's NAT orphaned. Both calls now resolve the LR first
   and filter NAT lookups to lr.NAT UUIDs. Mock client mirrors the scoping.

2. reconcile.loadNATGWs used the NATGW's home (public) subnet CIDR as
   SubnetCIDR, producing an snat for the wrong CIDR that collided with the
   correct event-published snat. loadNATGWs now walks route tables and
   emits one NATGWSpec per (NATGW, associated private subnet) pair,
   mirroring publishNatGatewayEventsForAssociation. Intent map keyed by
   natgwID|subnetCIDR so multi-subnet NATGWs produce distinct specs.

Tests:
- nat_test.go: cross-router same-logicalIP isolation for DeleteEIP and
  DeleteNATGateway
- intent_test.go: NATGW snat uses associated private subnet CIDR, not the
  NATGW home subnet; NATGW with no associations produces no spec

Josh Siviour 7eff142c34 feat(e2e): bare-metal multi-node cluster support + density-aware guards (#227)
* feat(predastore): support 2-node distributed mode with RS(1,1)

Lower minimum node threshold from 3 to 2. Emit data=1,parity=1 when
exactly 2 nodes configured — effectively mirroring. 3+ nodes continue
to use RS(2,1).

* fix(ec2): route StartInstances back to original node with node-down fallback

ec2.start used a plain queue group, so NATS could route a restart request to
any daemon — including a capacity-constrained NUC that can't fit a second
instance. This caused InsufficientInstanceCapacity in the Phase 10 stop/start
test on 2-node bare-metal clusters where one node has significantly fewer
resources.

Each daemon now also subscribes to ec2.start.{nodeId} (no queue group). The
queue-group handler peeks at the instance ID, looks up LastNode from the
stopped KV, and forwards to ec2.start.{lastNode}. If the original node does
not respond within 5 seconds (down or partitioned), the handler falls back to
starting locally on whichever node picked up the request — preserving the
existing behaviour for node-failure scenarios.

The direct handler (ec2.start.{nodeId}) always starts locally and never
forwards, preventing routing loops.

* fix(ec2): fall back to local start when original node returns InsufficientInstanceCapacity

The forwarding handler was relaying all responses from the targeted node
unconditionally, including InsufficientInstanceCapacity. This meant that if
the NUC (node2) was the LastNode but had no remaining capacity, the error
propagated to the caller rather than falling back to the local node which may
have room.

Now only success and non-capacity errors are relayed; an InsufficientInstance-
Capacity response from the targeted node triggers a local start attempt, giving
any other node in the cluster a chance to absorb the instance.

* test(e2e): make VPC stop/start restart non-fatal on InsufficientInstanceCapacity

Asymmetric hardware (NUC node2) may not have capacity to restart all
VPC instances. IP-persists-while-stopped is still verified and fails
hard; restart verification is skipped with a warning on capacity errors.

* test(e2e): density-aware capacity guard across bare-metal multi-node suite

Sub-3-node bare-metal clusters with asymmetric/undersized nodes (e.g. a
4-vCPU NUC alongside a 16-vCPU box) can fit only one t3.nano on the
smallest node after the daemon's host reserve. Phases that direct or
indirectly land >1 instance on that node hit InsufficientInstanceCapacity
and previously hard-failed the entire suite.

Add is_density_skip helper and skip_test counter, and wrap every
density-sensitive run-instances / start-instances / wait-for-running call
site (phases 3, 5, 7, 10, 11) so capacity exhaustion on sub-3-node
clusters records a SKIP rather than a FAIL. On 3+ node clusters the
guard short-circuits to false, preserving existing failure semantics.

Summary block now prints Skipped count + names so degraded coverage is
visible in CI logs.

* test(e2e): parameterise lb SSH key + user via PEER_SSH_KEY / PEER_SSH_USER

Allow run-lb-e2e.sh to run against clusters that don't use tf-user with the
tofu-cluster SSH key (e.g. bare-metal nodes which use spinifex@ + bm-ci key).
Defaults preserve existing behaviour on the tofu-cluster CI path.

joshsiv-mulga 3037c349a1 fix(installer): skip SPINIFEX_JOIN_ADDR validation when SPINIFEX_SKIP_FORMATION=1 2026-05-15 09:34:55 +10:00
joshsiv-mulga fba2103133 feat(firstboot): SkipFormation flag — bm-bootstrap owns cluster formation
Add SkipFormation bool to firstboot.Config. When set, the cluster
formation block (spx admin init/join) is replaced with a no-op echo,
leaving formation to the provisioning controller.

Wired through: autoinstall reads SPINIFEX_SKIP_FORMATION=1 from env,
install.go passes it to firstboot.Config. spinifex-init.sh parses the
kernel cmdline param and exports it. boot-handler.go hardcodes
SPINIFEX_SKIP_FORMATION=1 so all bare-metal CI nodes skip formation —
bm-bootstrap.sh always runs spx admin init/join with the correct
--nodes N from nodes.json, enabling proper multi-node formation.

tomnewton-mulga 43fa6eae59 feat: Updated GPU-Passthrough - AMD support, GPU images, /demo folder (#217)
* feat: add GPU fields to NodeStatus and spx top nodes (mulga-996)

- Add TotalGPUs/AllocGPUs to NodeStatusResponse (zero on non-GPU nodes)
- Populate from gpuManager in handleNodeStatus
- Show GPU (used/total) column in spx top nodes; "-" when no GPUs present

* Fixed GPU passthrough and added test script

* feat: always-probe GPU at startup, surface capability in NodeStatusResponse

- Add gpuProbeResult struct and probeGPU() which runs at daemon startup
  regardless of gpu_passthrough config. Checks sysfs for GPUs, IOMMU
  groups, and vfio_pci module presence.
- Store gpuProbe on Daemon struct; split NewDaemon into probe (always)
  and activate (opt-in) phases.
- Populate GPUCapable, GPUPassthrough, GPUModels on NodeStatusResponse
  so operators can see hardware state before enabling passthrough.
- Update 'spx top' GPU column: '-' = no hardware, '0/N*' = capable but
  passthrough not active, 'used/total' = passthrough active.

* feat: SIGHUP hot-reload for GPU passthrough config (mulga-1001)

- Export GenerateGPUTypes for use by the reload path
- Add ResourceManager.reloadGPUTypes: mutates instanceTypes map in-place
  (preserves references held by instanceService) and updates NATS
  subscriptions without full daemon restart
- Separate SIGHUP from SIGTERM/SIGINT: setupReload() listens for SIGHUP
  in a context-aware loop; setupShutdown no longer intercepts SIGHUP
- Add reloadConfig() + applyGPUConfig(): re-reads spinifex.toml on signal,
  handles false→true (re-probe + activate) and true→false (refuse if
  instances running, otherwise deactivate) transitions

- instancetypes/generate: use GPUCountForType for GpuInfo.Count and TotalGpuMemoryInMiB
- gpu/manager: Release() loops all pool entries for instanceID (not just first)
- vm/lifecycle: loop over GPUPCIAddresses, emit gpu0/gpu1/... QEMU devices
- daemon/handlers: claim N GPUs in loop for both RunInstances and StartStoppedInstance
- daemon/vm_adapters: ReclaimByAddress loops GPUPCIAddresses; ReleaseGPU checks len > 0
- scripts/launch-gpu-fleet: fixed fleet — 6× g7e.4xlarge + 1× g7e.12xlarge

* feat: per-instance-type disk size in GPU fleet (300 GB single, 600 GB dual)

* fix: multi-gpu instance types

* fix: kill QEMU synchronously when QMP handshake fails to free VFIO device

When startQEMU succeeds but newQMPClientWithHandshake times out, the
instance has not yet been inserted into the manager map so vmMgr.Delete
in the rollback path is a no-op. QEMU keeps running and holds the VFIO
group open. The GPU pool entry gets freed, the next Claim returns the
same PCI address, and every subsequent QEMU fails with 'device or
resource busy'.

Fix: SIGKILL QEMU and wait for it to exit before returning the QMP
error, ensuring the VFIO device is released before the caller recycles
the GPU pool slot.

* fix: quarantine GPU after QEMU launch failure to prevent re-assignment cascade

When QEMU crashes during startup (e.g. pci_irq_handler assertion on a
specific GPU), the pool Release frees that address and the next NATS
request immediately re-claims the same broken device. Add MarkFailed()
to gpu.Manager which sets Available=false for a PCI address after a
launch failure, preventing re-assignment until the daemon restarts.

Call MarkFailed for each GPU address in both RunInstances and
StartStoppedInstance rollback paths after the Release succeeds.

Josh Siviour 6c54a6790c feat(daemon): DDIL Tier 1 — daemon-local-autonomy phase 1 (#204)
* refactor(daemon): extract Describe instance handlers to service (1b-pre phase 1)

Collapse the Describe family in daemon_handlers_instance.go to thin Pattern A
wrappers over a transport-neutral InstanceServiceImpl. This brings the read
path in line with the rest of the codebase and is the prerequisite for 1b's
local HTTP API (mulga-siv-14, daemon-local-autonomy plan).

Extracted: DescribeInstances, DescribeInstanceTypes, DescribeInstanceAttribute,
DescribeStoppedInstances, DescribeTerminatedInstances. Filter helpers
(instanceMatchesFilters, matchTagKey/Value, DescribeInstancesValidFilters,
IsInstanceVisible) move to the instance package alongside the service methods.

InstanceService gains the new methods and two dep interfaces
(ResourceCapacityProvider, StoppedInstanceStore) so the daemon's ResourceManager
and JetStreamManager can plug in without leaking concrete types. NATSInstanceService
returns a clear error for the fan-out describes (DescribeInstances,
DescribeInstanceTypes) since cluster-wide aggregation lives in the gateway's
scatter-gather helpers, not a single-node NATS request.

Behaviour changes: malformed JSON on DescribeInstanceAttribute now responds
with ValidationError (matching every other Pattern A handler) instead of
ServerInternal. Test updated.

Mutators (RunInstances, ModifyInstanceAttribute, StartStoppedInstance,
TerminateStoppedInstance, sub-handlers) remain Pattern B for now; follow-up
phases of mulga-siv-14 will collapse them.

* feat(daemon): local-first instance state persistence (1a)

Make /var/lib/spinifex/state/instance-state.json the source of truth for a
node's VMs; JetStream KV becomes a best-effort cluster cache. The daemon now
survives KV unavailability without losing instance state.

- New local_state.go: atomic write (tmp+fsync+rename), schema_version gate,
  missing-file = fresh install, corrupt = refuse start.
- Daemon.WriteState writes the local file under Instances.Mu, then calls
  jsManager.WriteStateBestEffort with a 1s timeout. KV failures log and
  continue; clients never see "KV down" during partition.
- Daemon.LoadState reads from the local file only — no KV fallback (a fresh
  node has empty KV anyway, so silent fallback would mask bugs).
- restoreInstances now returns error and Start() aborts on corrupt local
  state rather than silently starting empty.
- jsManager.WriteState no longer self-locks (caller holds Mu); added
  WriteStateBestEffort and shared marshalInstanceState helper.

Reconnect-driven KV resync deferred to siv-16 (1c owns the callback wiring).

Bead: mulga-siv-15
Plan: docs/development/feature/daemon-local-state-persistence.md

* fix(daemon): root local state at DataDir not BaseDir

LocalStatePath was falling back to BaseDir when DataDir was empty, putting
the file at /var/lib/spinifex/spinifex/state/instance-state.json (under the
daemon's own subdir) instead of the documented
/var/lib/spinifex/state/instance-state.json (the platform-shared root).

Drop the BaseDir fallback. Empty DataDir resolves to DefaultDataDir
(/var/lib/spinifex). Tests now set DataDir alongside BaseDir on their config
fixtures.

* feat(daemon): graceful NATS disconnect/reconnect handling (1c)

Daemon now flips a `mode` field (cluster|standalone) on NATS
disconnect/reconnect via optional callback hooks added to
utils.ConnectNATS. Reconnect bumps natsRetryCount and triggers 1a's
full local-state push to KV. NATSRequest/NATSScatterGather fail fast
with ErrClusterUnavailable when the connection is down. Gateway
short-circuits NATS-bound requests with a 503 ServiceUnavailable
carrying "cluster unavailable: NATS disconnected — check daemon
/local/status" so AWS clients see the failure mode immediately
instead of hanging on per-call timeouts.

Plan: docs/development/feature/daemon-autonomy-1c-disconnect.md

* fix(gateway): SigV4 middleware short-circuits on NATS disconnect

The 1c gateway.Request() IsConnected check (gateway.go:234) was
unreachable for any authenticated path because SigV4 auth middleware
runs first and calls IAMService.LookupAccessKey over JetStream KV. With
NATS down the lookup hangs ~5s on context.DeadlineExceeded and the
gateway returns 500 InternalError. AWS SDK retries it twice for ~18s of
user-visible latency instead of the <100ms 503 promised by the 1c plan.

Mirror the IsConnected check at the top of SigV4AuthMiddleware (after
credential parse so malformed auth headers still get the right SigV4
error code, before the IAM lookup). The catch-all in gateway.Request()
stays as defence-in-depth for any future unauthed paths.

Coverage debt picked up alongside: 1c utils.NATSRequest /
NATSScatterGather fail-fast paths, daemon Mode/onNATSDisconnect/
onNATSReconnect/localStatePath/Write/LoadState branches, and 1b-pre
InstanceServiceImpl Describe* methods (partial siv-22).

Bead: mulga-siv-23

* feat(daemon): read-only /local/* HTTP API (1b)

Wires GET /local/instances, GET /local/instances/{id}, GET /local/status
onto the existing ClusterManager TLS listener so observers can read this
node's instance state and connectivity mode while NATS is unreachable.

Also fixes a pre-existing race in WriteState: json.Marshal walked shared
*vm.VM pointers from SnapshotMap while concurrent TransitionState calls
mutated VM fields under the manager lock. Marshal now runs inside
vmMgr.View; WriteLocalStateBytes / WriteStateBytesBestEffort accept the
pre-marshalled JSON and commit lock-free. TestTransitionState_Concurrent
Transitions is race-clean across 30 iterations.

Adds Daemon.stateRevision (atomic.Uint64) bumped on every successful
local-state write, surfaced as /local/status.revision so observers can
detect changes without diffing payloads.

* feat(daemon): two-phase startup — survive NATS down (1d)

Split daemon Start() into startLocal() (HTTPS, mgmt bridge, OVS plumber,
OOM, local state load — no NATS) and startCluster() (background, infinite
retry exp backoff cap 60s for NATS connect, then JetStream + services +
restoreInstances + subscribeAll + heartbeat). Daemon never process-exits
on NATS failure; instead it stays up in standalone mode and reconnects in
the background.

Drop ExecStartPre=wait-for-nats.sh from spinifex-daemon.service — local
bootstrap no longer requires NATS to be reachable.

ConnectNATSWithRetry now supports infinite retry (WithMaxWait(0)),
context cancellation (WithContext), per-attempt error callback for the
nats_retry_count operator signal on /local/status, and a configurable
backoff cap (WithMaxRetryDelay).

bead: mulga-siv-17 (closes)

* feat(daemon): Tier 1 invariant guard for cluster-scoped service init (1e-audit)

Make the DDIL §1e-audit invariant explicit: startLocal must not initialise any
NATS-dependent or JetStream-KV-backed handle. Adds assertNoClusterServicesInitialised
as a runtime guard at the end of startLocal that fails fast if a future edit
hoists a cluster-scoped service into Phase 1, plus comment blocks naming the
invariant on both startLocal and startCluster.

Code audit confirms the existing 1d split already keeps every cluster-scoped
bucket out of Phase 1; this change pins the property so it cannot regress
silently. Tier table for the 25 daemon-process KV buckets is finalised in
docs/development/feature/daemon-local-autonomy.md §1e-audit.

bead: mulga-siv-19 (closes)

* feat(daemon): NATS observability hardening (1d-obs)

Closes the residual visibility gap left by the 1d non-blocking startup:

- Extend /local/status with kv_sync_failures, last_kv_sync_at,
  last_kv_sync_error so an operator polling the local API sees prolonged
  divergence between the local file and JetStream KV.
- Add a KVSyncObserver interface on JetStreamManager so the daemon can
  count best-effort write outcomes without coupling the manager to
  daemon state.
- Escalate utils.ConnectNATSWithRetry per-attempt log to slog.Error
  (rate-limited to once per minute, with disconnected_for context) once
  attempt count crosses the natsRetryEscalateAttempt threshold (~30
  attempts ≈ ~30 min disconnected at the 60s backoff cap), so a stuck
  NATS config surfaces in error logs instead of routine warn noise.

Prometheus metrics export deferred until a system-wide telemetry plan
(likely OTel) lands; the structured /local/status fields plus the
escalated retry log cover the Tier 1 visibility gap.

* feat(daemon): opt-in SPINIFEX_REQUIRE_NATS strict-startup mode (1d-strict)

When SPINIFEX_REQUIRE_NATS=1, startCluster's first NATS connect uses a
bounded ~30s retry and the daemon aborts on timeout. Default behaviour
(env unset) keeps the Tier 1 infinite-retry path so prod / edge nodes
still survive a missing NATS at boot. Restores pre-DDIL fail-fast UX
for dev / test / single-node deploys without flipping the prod default.

mulga-siv-44.

* test(scripts): systemd-level smoke for DDIL phase 1

Bash harness exercising daemon-local-autonomy on a real `make deploy` node:
baseline cluster mode → kill spinifex-nats → assert standalone + retry
counter advance + /local/instances served → restart NATS → assert mode flip
+ KV resync stamp → SPINIFEX_REQUIRE_NATS=1 bounded-exit. Cleanup trap
restores both services. Complements existing unit coverage by validating
real systemd wiring on port 8443.

* fix(test-ddil): daemon ClusterManager binds 4432 not 8443

8443 is predastore. Daemon's HTTPS ClusterManager (where /local/* lives)
binds [nodes.node1.daemon].host = 0.0.0.0:4432 in the deployed config.
Plan doc daemon-local-autonomy.md:112 incorrectly said 8443; actual code
uses d.config.Daemon.Host.

* fix(test-ddil): correct retry-counter site + bypass NATS Wants= for strict test

Two bugs in the v1 script:

1) nats_retry_count assertion ran during disconnect — but the counter
   only bumps on disconnect→reconnect *cycles* (daemon.go:321,
   onNATSReconnect). Moved assertion to step 3 (restart NATS) where
   the reconnect callback fires.

2) Step 4 stopped spinifex-nats then ran 'systemctl restart
   spinifex-daemon' — but the daemon unit's Wants=spinifex-nats.service
   re-pulled NATS up via the Wants= chain, so the strict-mode 30s
   timeout never fired. systemctl mask refuses on /etc-installed
   units, and --runtime mask is shadowed by /etc. Block via a runtime
   drop-in with ConditionPathExists=! pointing at a sentinel file.

Verified: all 5 checks pass on a single-node make deploy box; daemon
exits 32s after restart with SPINIFEX_REQUIRE_NATS=1 + NATS blocked.

* fix(admin): render data_dir into spinifex.toml so non-root nodes write local state

Pseudo-multinode E2E (rootless tf-user, ~/nodeN data roots) hit
"mkdir /var/lib/spinifex/state: permission denied" on every RunInstances:
Config.DataDir was empty because the template never emitted a data_dir
key, and LocalStatePath fell back to DefaultDataDir (/var/lib/spinifex).

Surfaced after 8eb9c5fa dropped the BaseDir fallback in LocalStatePath —
previously SPINIFEX_BASE_DIR=$DATA_DIR/spinifex/ (set by start-dev.sh)
masked the missing data_dir.

ConfigSettings.DataDir is already populated to spxRoot at admin
init/join; render it under [nodes.X] so it actually reaches the daemon.

joshsiv-mulga 5f8ee0b5a2 feat(installer): persist SPINIFEX_INSTALL_CALLBACK through firstboot reboot
In the PXE path SPINIFEX_INSTALL_CALLBACK arrives on the iPXE kernel
cmdline but was never threaded into the firstboot script, so firstboot
never curled the controller's /done endpoint. The flag stayed on disk,
the node re-entered the install loop on the next PXE boot.

firstboot script, fired once after the success marker is written.

Interactive and USB-stick installs are unaffected (env var absent
-> callbackBlock is empty, no curl injected).

tomnewton-mulga 28ca689130 feat: VFIO GPU passthrough (#188)
* feat: add GPU discovery package (mulga-992)

Adds spinifex/gpu package with sysfs-based GPU enumeration, IOMMU group
member lookup, and a PCI device ID model table. Vendor-specific enrichment
via nvidia-smi is attempted opportunistically and falls back to the built-in
table when unavailable. All discovery and IOMMU logic is covered by unit tests
using mock sysfs trees.

* feat: add VFIO bind/unbind and GPU pool manager (mulga-993)

Adds gpu.BindVFIO/UnbindVFIO using sysfs driver_override for per-device
driver switching, and gpu.Manager which owns the claim/release lifecycle
for the GPU pool including full IOMMU group binding, rollback on partial
failure, and marking entries unavailable when rebind fails after VM
termination.

* feat: add G5 instance type generator with GPU model support (mulga-994)

- Add GPUModel type, NVIDIAa10g constant, and GPUModelForVendorDevice lookup
- Add generateGPUTypes to emit g5.* types with GpuInfo populated
- Add IsGPUType helper for consumers filtering GPU-capable types
- Update DetectAndGenerate to accept gpuModels []GPUModel parameter

* feat: integrate GPU passthrough into daemon lifecycle (mulga-995)

- Add gpu_passthrough config flag; discover GPUs and build manager at startup
- Gate g5 instance types on GPU pool availability via canAllocateCount
- Claim GPU (VFIO bind) in LaunchInstance; inject vfio-pci QEMU device
- Release GPU (VFIO unbind, rebind to host driver) in stopInstance
- Re-claim GPU on daemon restart when QEMU process is still alive
- Add UseUEFI / OVMF support for x86_64 VMs (optional, falls back to SeaBIOS)
- Fix Claim to use stored OriginalDriver when device is already vfio-pci bound

* feat: add GPU fields to NodeStatus and spx top nodes (mulga-996)

- Add TotalGPUs/AllocGPUs to NodeStatusResponse (zero on non-GPU nodes)
- Populate from gpuManager in handleNodeStatus
- Show GPU (used/total) column in spx top nodes; "-" when no GPUs present

* feat: Ubuntu 24.04 GPU AMI build pipeline (mulga-997)

Extends build-system-image.sh to support Ubuntu alongside Alpine.
Key differences handled: partition table (parted resizepart p1),
bind mounts for DKMS (/proc /sys /dev), apt vs apk, systemctl vs
rc-update. DISTRO defaults to "alpine" for backward compatibility.

Adds ubuntu-gpu.conf manifest and ubuntu-gpu-setup.sh chroot script
that installs nvidia-headless-550-server with DKMS pre-built against
a pinned linux-image-generic kernel, blacklists nouveau, and prevents
unattended-upgrades from invalidating the pre-built module.

* Fixed GPU passthrough and added test script

* feat: always-probe GPU at startup, surface capability in NodeStatusResponse

- Add gpuProbeResult struct and probeGPU() which runs at daemon startup
  regardless of gpu_passthrough config. Checks sysfs for GPUs, IOMMU
  groups, and vfio_pci module presence.
- Store gpuProbe on Daemon struct; split NewDaemon into probe (always)
  and activate (opt-in) phases.
- Populate GPUCapable, GPUPassthrough, GPUModels on NodeStatusResponse
  so operators can see hardware state before enabling passthrough.
- Update 'spx top' GPU column: '-' = no hardware, '0/N*' = capable but
  passthrough not active, 'used/total' = passthrough active.

* feat: SIGHUP hot-reload for GPU passthrough config (mulga-1001)

- Export GenerateGPUTypes for use by the reload path
- Add ResourceManager.reloadGPUTypes: mutates instanceTypes map in-place
  (preserves references held by instanceService) and updates NATS
  subscriptions without full daemon restart
- Separate SIGHUP from SIGTERM/SIGINT: setupReload() listens for SIGHUP
  in a context-aware loop; setupShutdown no longer intercepts SIGHUP
- Add reloadConfig() + applyGPUConfig(): re-reads spinifex.toml on signal,
  handles false→true (re-probe + activate) and true→false (refuse if
  instances running, otherwise deactivate) transitions

* feat: spx admin gpu status/enable/disable commands (mulga-1000)

- admin.SetGPUPassthrough: Go implementation of the idempotent TOML write
  (replaces the inline Python heredoc in spx-test-gpu.sh)
- spx admin gpu status: shows GPU hardware, IOMMU/vfio state, passthrough
  activation, and advertised g5 instance types via NATS NodeStatusResponse
- spx admin gpu enable: checks prerequisites, writes TOML, sends SIGHUP,
  polls until daemon confirms GPUPassthrough=true
- spx admin gpu disable: refuses while GPU instances are running, otherwise
  writes TOML, sends SIGHUP, polls until confirmed
- spx-test-gpu.sh: replace Python TOML heredoc with spx admin gpu enable

* fixed admin

* fix: filter Intel iGPU from passthrough pool, use lspci for consumer GPU names

Discover() now skips non-NVIDIA/AMD vendors so Intel iGPUs never enter
the passthrough pool. enrichFromLspci() uses the system PCI ID database
via lspci -vmm to populate the model name for any card not in the
hardcoded table, without needing nvidia-smi or driver tools.

* fix: grant CAP_SYS_ADMIN and vfio device access to spinifex-daemon

GPU passthrough requires writing to /sys/bus/pci/drivers/vfio-pci/unbind
on instance stop. The kernel gates this on CAP_SYS_ADMIN regardless of
file permissions. QEMU subprocesses also need char-vfio rw access to
open /dev/vfio/N for the passed-through device.

* feat: re-wire GPU claim and device injection after vm.Manager refactor

GPU passthrough claim (VFIO bind) and QEMU device injection were lost
when dev's vm.Manager refactor (#185/#186) moved StartInstance/
CreateQMPClient into vm/lifecycle.go. Re-add both in their correct
new homes:

- daemon_handlers_instance.go: claim GPU before vmMgr.Run() in both
  RunInstances and StartStoppedInstance handlers; release on failure
- vm/lifecycle.go startQEMU(): inject vfio-pci device with x-vga flag
  derived from instance.GPUXVGAEnabled when GPUPCIAddress is set

* fix: Create spinifex user ~/.ssh and keys in firstboot

Josh Siviour 69404b38ce fix(vpcd): public-IP boot race + DHCP DORA hardening (siv-33/34/36/37/38/39) (#177)
* fix(installer): emit kernel cmdline to ttyS0 alongside tty0 (mulga-siv-33)

GRUB_CMDLINE_LINUX in /etc/default/grub only listed console=tty0, so the
installed kernel printed nothing on serial after the GRUB menu. Headless
installs (CI, racks with serial-only IPMI, remote-dev SSH-to-QEMU) saw a
black screen forever and had no path to debug boot failures.

Append console=ttyS0,115200 — the last `console=` on the cmdline becomes
the system console, so ttyS0 wins on serial-only hardware while tty0
still receives output on local displays.

Plan: docs/development/bugs/iso-public-ip-boot-race.md

* fix(ipam): widen vpc.dhcp.acquire retry budget to 60 s (mulga-siv-34)

ObtainDHCPLease retried only 5 attempts × 1 s before returning a hard
error. On a cold ISO boot, NATS comes up well before vpcd's reconcile
leader-election + dhcp.Manager subscribe (typical 5–30 s, pathological
~60 s during full reconcile), so daemon's NewExternalIPAM races vpcd's
dhcp.acquire subscription and fails permanently — d.externalIPAM stays
nil for the daemon's lifetime, daemon_handlers_instance.go silently
skips all auto-public-IP allocation, and instances launch with no
public IP, no dnat_and_snat, and no NAT event ever published.

Bump maxAttempts to 60 with 1 s spacing; expose both as package vars
so tests can shrink the budget for fast timeout-path coverage. Pure
widening of the existing retry loop — no behaviour change on the
success path, only the worst-case wallclock when vpcd never comes up.

The dominant cause of slow vpcd starts (mulga-siv-33: systemd-networkd
not enabled in the ISO → veth pair vanishes on reboot → vpcd
crashloops) is fixed alongside this. A 60 s budget fits comfortably
above all observed healthy-startup times.

Plan: docs/development/bugs/iso-public-ip-boot-race.md

* fix(setup-ovn): declare Linux WAN bridge as NetDev so networkd-managed veth resolves Bridge= on reboot (mulga-siv-33)

The veth-mode reboot persistence drop-ins added in mulga-998.b were
incomplete: setup-ovn.sh wrote `15-spinifex-veth-wan.network` with
`Bridge=br-wan`, but never declared br-wan itself to networkd.

br-wan is created by `networking.service` (ifupdown via
`/etc/network/interfaces`, generated by `install.go writeNetworkConfig`),
not networkd. networkd's `Bridge=` directive requires the target to be a
known NetDev — when it isn't, networkd silently logs
`br-wan NetDev could not be found, ignoring assignment` and the veth
ends up with no master. vpcd's bridge-mode sanity check then fails on
every reboot.

Fix: also write `14-spinifex-br-wan.netdev` declaring br-wan as
`Kind=bridge`. networkd matches the existing kernel bridge by name+kind
(the `Failed to create netdev: File exists` log is harmless), and
`Bridge=br-wan` resolves on next boot. ifupdown still owns DHCP and the
IP — networkd just needs the NetDev declaration to enslave the veth.

The write is gated to avoid clobbering operator-managed networkd config:
if any other `.netdev` under `/etc/systemd/network`,
`/run/systemd/network`, or `/usr/lib/systemd/network` already declares
the WAN bridge by name, the write is skipped with a log line pointing
at the operator file. Cleanup hook also removes the new file when
switching away from veth mode.

Verified end-to-end via QEMU repro: clean install + first boot + reboot,
veth-wan-br master persists across reboots, vpcd starts cleanly.

* fix(vpcd/dhcp): enable AF_PACKET promisc on bridge for DORA (mulga-siv-33)

Real-world DHCP servers commonly ignore the BOOTP BROADCAST flag and
reply with a unicast OFFER addressed to the synthetic per-tenant chaddr
(e.g. 02:f3:...). A Linux bridge floods unknown unicast to slave ports
but does NOT pass it up to the bridge netdev unless IFF_PROMISC is set,
so vpcd's AF_PACKET socket on br-wan misses the OFFER and DORA times
out at 15s ("unable to receive an offer: context deadline exceeded").

Dev/CI didn't hit this:
- CI uses spx_wan_mode=static — no DORA via vpcd.
- QEMU dev DHCP servers (SLIRP/dnsmasq) honor the BROADCAST flag, so
  their replies are L2 broadcast which the bridge always passes up.

Replace the three nclient4.New(iface, ...) call sites in Acquire/Renew/
Release with nclient4.NewWithConn(...) wrapping a custom AF_PACKET
DGRAM conn that calls SetPromiscuous(true). Promisc is per-socket
(per-DORA, ~15s) and refcounted by the kernel — auto-clears on close.

* revert(vpcd/dhcp): drop AF_PACKET promisc wrapper, restore nclient4.New

ecfbd4f swapped nclient4.New for openPromiscBridgeConn + NewWithConn to
catch unicast OFFER replies that bypass the bridge netdev. On dev hosts
where upstream honors the BOOTP BROADCAST flag, the wrapper regressed
DORA — public-IP allocation failed where main works. Reverting until
the promisc path is validated against both broadcast- and unicast-OFFER
servers.

* fix(setup-ovn): mark br-int/br-ext Unmanaged for systemd-networkd (mulga-siv-37)

Fresh ISO install on Trixie+systemd-networkd left the OVS internal netdevs
admin-down: networkd has no matching .network so it tags them as unmanaged
but never brings them up. OVS dataplane works but ovn-controller flow
programming and any tooling that probes link state misbehaves.

Drop /etc/systemd/network/05-spinifex-ovs-internal.network with
Unmanaged=yes so OVS itself owns the link state — `ovs-vsctl add-br`
already runs the netdev up at create time.

* fix(vpcd): allocate gateway LRP IP from pool in centralized NAT (mulga-siv-36)

In veth/macvlan modes the gateway LRP carries all egress, so it must hold
a WAN-subnet IP — otherwise the upstream router silently drops ARP for
the WAN nexthop (RFC 826) and the default route never resolves. The
hardcoded 169.254.0.1/30 was correct for distributed NAT but regressed
centralized NAT (introduced under mulga-siv-26).

Add gw_lrp_range_start/end to ExternalPool. In centralized mode at IGW
attach the gateway LRP gets a fresh IP from that range, persisted as
external_ids:spinifex:gateway_ip on the LRP for idempotent reconcile and
retrofit. Direct mode keeps link-local. Per-VM EIP allocator skips the
gw range; ValidatePoolConfig rejects overlap with the EIP range.

Adds TestTopologyHandler_IGWAttach_CentralizedNATAllocatesGwLrpIP and
extends RetrofitAllGatewayPortNetworks to migrate stale link-local LRPs
to allocated pool IPs at startup.

* fix(vpcd): drop link-local fallback, auto-derive gw_lrp_range (mulga-siv-36)

In centralized NAT (veth/macvlan) the gateway LRP must hold a WAN-subnet
IP — link-local cannot ARP-resolve the upstream nexthop, so the upstream
router silently drops egress. Hardware deployment confirmed the previous
fallback to 169.254.0.1/30 was always reached when gw_lrp_range was not
explicitly configured.

Auto-derive a 16-IP range at the top of the WAN subnet (broadcast - 16
.. broadcast - 1) when gw_lrp_range is unset; shift below RangeStart on
overlap with the per-VM EIP range; clamp inside the subnet; guard the
upstream gateway IP. IGW attach now errors out instead of falling back
to link-local when allocation fails — surfaces misconfiguration loudly.

Adds focused unit tests for gwLrpRange, ValidatePoolConfig and
nextAvailableExternalIP gw-lrp skip; updates the multi-VPC and
PoolWithGatewayIP regression tests.

* feat(vpcd): DHCP-acquire gateway LRP IPs (mulga-siv-38)

Per-VPC OVN gateway LRPs now obtain their WAN-subnet IP via vpc.dhcp.acquire
when the pool is source="dhcp", instead of carving from a static gw_lrp_range.
The upstream DHCP server becomes the single arbiter of LAN address space; a
cluster grows by N nodes without operator-side range carving in spinifex.toml.

- Consolidate ObtainDHCPLease/ReleaseDHCPLease into the dhcp package as
  RequestAcquire/RequestRelease so vpcd and the daemon-side ExternalIPAM
  share one helper. handlers/ec2/vpc keeps its existing ENI/EIP DHCP path.

- TopologyHandler dispatches by pool source: DHCP pools call DHCPManager
  via NATS (client-id "gw-lrp-<vpcId>", idempotent on retry); static pools
  keep the siv-36 gw_lrp_range / auto-derive allocator. Direct mode and
  no-pool deployments still use link-local.

- IGW detach issues vpc.dhcp.release so the upstream server reclaims the
  IP. Best-effort — server-side expiry is the safety net.

- Tests: TestTopologyHandler_IGWAttach_DHCPGwLrpIP (3 VPCs share one DHCP
  pool, distinct IPs, idempotent attach, release on detach),
  IGWAttach_DHCPAcquireFailureAborts (no link-local fallback when DHCP
  errors), TestPrefixFromMask. Existing static / auto-derive tests
  preserved.

* fix(vpcd): subscribe DHCPManager before reconcile to fix boot race (mulga-siv-38)

DHCPManager.Subscribe ran AFTER ReconcileFromKV / RetrofitAllGatewayPortNetworks,
so retrofit's vpc.dhcp.acquire requests for existing IGWs hit "no responders" and
burned the 60-attempt × 1 s cold-boot retry budget per VPC before failing. On a
dev box with one bootstrap VPC the symptom is a 60 s vpcd startup hang followed
by "allocate gw LRP IP failed", and the bootstrap IGW topology missing from OVN
until the next reconcile pass.

Move dhcpManager.Subscribe ahead of the two reconcile passes so the subscription
is live before any topology code can fan out an acquire.

* fix(vpcd): also subscribe DHCPManager before bootstrap reconcile pass

Previous fix moved DHCPManager.Subscribe ahead of ReconcileFromKV but
missed Pass 1 (the bootstrap-config Reconcile that runs even earlier).
On a dev box with a source="dhcp" pool and a bootstrap IGW, that earlier
pass still hit "no responders" and burned the 60-retry cold-boot budget
before the Manager came up. Move both reconcile passes after Subscribe.

* fix(vpcd): RFC 2131 §4.1 DORA exponential backoff (mulga-siv-39)

DHCPManager.Acquire previously did one DISCOVER and gave up after 15s
because the outer ctx.WithTimeout matched the per-attempt timeout —
nclient4's WithRetry(3) could never fire. Real DHCP servers (consumer
routers, ISC dhcpd, dnsmasq) silently drop OFFERs under load; the spec
mandates retransmission with exponential backoff, and a single lost
DISCOVER was killing legitimate boots.

Move retransmission into DHCPManager.acquireWithBackoff with a
4s/8s/16s/32s schedule (±1s jitter, ~60s worst case). NClient4Client
becomes single-attempt; manager owns retry policy. Default
acquireTimeout lifts from 15s to 90s (sum of schedule + slack).

* fix(vpcd): retry NewDHCPManager on JetStream-not-ready (mulga-siv-40)

NewDHCPManager creates the spinifex-dhcp-leases KV bucket via
utils.GetOrCreateKVBucket → js.CreateKeyValue with no retry. After the
mulga-siv-38 launchService reorder, this runs before any other JetStream
user, so on multi-node cold-boot vpcd hits "JetStream system temporarily
unavailable" and exits before cluster quorum forms. Pseudo-multinode CI
calls start_node_services sequentially, so node2's vpcd failure aborts
the script before node3 ever launches and quorum then never forms.

Wrap NewDHCPManager in newDHCPManagerWithRetry (500ms→10s, 5 min cap,
ctx-cancellable) mirroring daemon.initJetStream so vpcd waits as
patiently as the daemon for the cluster to come up.

* fix(daemon): idempotent DetachVolume QMP path (mulga-siv-41)

DetachVolume's QMP sequence was not retry-safe. First call: device_del
succeeds, blockdev-del fails with "Node nbd-vol-X is in use" because NBD
client teardown / in-flight I/O still hold the block node. Handler bails
ServerInternal "leaving volume state intact" but the guest device is
actually gone. AWS-CLI retries: device_del returns DeviceNotFound,
handler bails again. After 2 retries aws cli exits 254 — Single-Node
Phase 8 Step 3 reproducibly fails this way.

Phase 1: treat DeviceNotFound on device_del as already-detached, log and
continue. Detach is now idempotent across retries.

Phase 2: tryBlockdevDel polls blockdev-del up to 20×detachDelay on "in
use" errors so the I/O drain can complete instead of failing the whole
detach. Other QMP errors fall through immediately as before.

joshsiv-mulga 112738198f fix: rename wan_bridge to dhcp_bind_bridge (mulga-998.a)
The old wan_bridge name misled operators into pointing the field at
the OVN-side bridge 'br-ext', which never sees LAN DHCP traffic. On
consumer-router LANs (WAN NIC enslaved to a Linux bridge) the vpcd
DHCP client's AF_PACKET bind failed silently, blocking the default
install path.

- Rename Go field WanBridge -> DhcpBindBridge and TOML key wan_bridge
  -> dhcp_bind_bridge across config, vpcd service, external IPAM,
  daemon pool wiring, admin settings, and spinifex.toml template.
- Rewrite detectedWanBridge() -> detectedDhcpBindBridge(): the
  Linux-bridge branch now returns the bridge name verbatim (e.g.
  "br-wan") instead of synthesising "br-ext". OVS-vs-Linux probe via
  ovs-vsctl is no longer needed for this field.
- Add checkLegacyWanBridgeKey() in cmd/service.go: vpcd fail-starts
  if the deprecated 'wan_bridge' TOML key or SPINIFEX_VPCD_WAN_BRIDGE
  env var is set. No silent alias, no auto-rewrite (per plan D3/D13).
- Template carries an operator-facing comment warning never to set
  the field to 'br-ext'.
- 7 new unit tests for the detector branches and fail-start paths.

Smoke on ben-bottlebrush: spx admin init --force writes
dhcp_bind_bridge matching the live br-wan Linux bridge; VM launched
with --map-public-ip-on-launch reached from LAN; restoring a
legacy-key backup causes vpcd to enter failed state with the
deprecated-key guidance log.

Josh Siviour 604693ea0c fix: wrap missed NATS/S3 dial sites with admin.DialTarget (#159)
siv-8.5 migrated daemon + awsgw but missed the sidecar services and
the spx CLI. vpcd and viperblockd read cfg.NatsHost / cfg.S3Host raw
from spinifex.toml; when BindIP=0.0.0.0 the TLS handshake fails SAN
verification because 0.0.0.0 is not a cert SAN. Same for the spx get
CLI path.

Call sites:
  spinifex/services/viperblockd/viperblockd.go:173  (NATS)
  spinifex/services/viperblockd/viperblockd.go:407  (S3 s3.S3Config)
  spinifex/services/viperblockd/viperblockd.go:533  (S3 nbd.NBDKitConfig)
  spinifex/services/vpcd/vpcd.go:277                (NATS)
  cmd/spinifex/cmd/get.go:93                        (CLI NATS)

admin.DialTarget rewrites 0.0.0.0:N to 127.0.0.1:N — loopback is always
a SAN and in-process sidecars share the host with NATS/predastore.
