* refactor: move Ochre serving lifecycle to the Ochre domain

handlers/bedrock becomes domains/ochre. Ochre is the platform service;
Bedrock names only its AWS API surface. Persisted and observable
identifiers keep their bedrock names.

* docs: record Ochre domain move

* refactor: move Ochre vector store to the Ochre domain

handlers/ochrevector becomes domains/ochre/vector. Callers import it as
ochrevector because vector is a common local name in the gateway.

* docs: record Ochre vector store move

* refactor: move Hugging Face Hub client to the Ochre domain

gateway/bedrock/hfhub becomes domains/ochre/hfhub. Its only caller is
the spx admin ochre weights pull.

* docs: record Hugging Face Hub client move and Ochre gateway debt

* refactor: move EC2 tag mutation helpers to the EC2 domain

utils/tagmirror.go becomes domains/ec2/tagmirror. It is EC2-wide tag
mutation behaviour, and the tags resource package cannot host it
without a resource-to-resource import cycle.

* docs: record EC2 tag mutation move and migrate split finding

* refactor: move network packages under the network domain

Move spinifex/network/* to spinifex/domains/network/* as one enclosing
move so the L0-L5 layer invariants keep classifying every package from
a single root. Package names and dependency direction are unchanged;
invariant scan roots, the RG-10 sudo allow-list path, CODEOWNERS and
the repo-root walk in the IMDS netns unit test follow the new path.

* docs: record network domain move

* refactor: move standalone EC2 resource packages to the EC2 domain

Move handlers/ec2/{account,key,launchtemplate,placementgroup,
spotinstance,volumestate} to domains/ec2/<resource>. Each package is
named after its directory and callers import it as ec2<resource>;
volumestate already carried its directory name.

* docs: record standalone EC2 resource moves

* refactor: move EC2 VPC networking packages to the EC2 domain

Move handlers/ec2/{vpc,eigw,eip,igw,natgw,routetable} to
domains/ec2/<resource>, each named after its directory and imported as
ec2<resource>. The reconcile drift-watch source scan now matches the
ec2<resource> bucket qualifiers; its rule is unchanged.

* docs: record EC2 VPC networking moves

* refactor: move EC2 compute and storage packages to the EC2 domain

Move handlers/ec2/{instance,volume,snapshot,image,tags} to
domains/ec2/<resource>, each named after its directory and imported as
ec2<resource>, which empties handlers/ec2. The daemon's e2e suite
selection now lists the moved EC2 resource paths in place of
handlers/ec2, so EC2-only changes select the daemon suites again.

* docs: record EC2 compute and storage moves

* refactor: move ECR credential provider to the EKS agent tree

Move the kubelet exec credential provider implementation from
cmd/ecr-credential-provider to agents/eks/credentialprovider, exposing
one Main(in, out) entry point. The binary keeps its name and FIPS boot
import as a thin main. Moving out of cmd/ brings the code under gosec;
the one G101 hit on the kubelet API version constant is annotated.

* docs: record ECR credential provider move

* refactor: move EKS gateway publish helper to the EKS agent tree

Move the eks-gateway-publish implementation to agents/eks/gatewaypublish
behind Run(ctx, Config) error. The binary keeps flag definitions,
environment defaults, parsing, its log prefix and exit code; each former
fatal site returns an error with the same text. The retry wait now also
honours context cancellation, which the binary never triggers.

* docs: record EKS gateway publish move

* refactor: move EKS gateway fetch helper to the EKS agent tree

Move the eks-gateway-fetch implementation to agents/eks/gatewayfetch
behind Run(ctx, Config) error, writing its TSV to Config.Out. The binary
keeps flag definitions, environment defaults, parsing, its log prefix and
exit code; each former fatal site returns an error with the same text.

* docs: record EKS gateway fetch move

* refactor: move EKS webhook cert helper to the EKS agent tree

cmd/eks-webhook-cert keeps flag parsing, the log prefix and the exit;
agents/eks/webhookcert owns Config and Run. Output, error text, file
modes and exit codes are unchanged.

* docs: record EKS webhook cert move

* refactor: move EKS konnectivity cert helper to the EKS agent tree

cmd/eks-konnectivity-cert keeps flag parsing, the log prefix and the
exit; agents/eks/konnectivitycert owns Config and Run. Output, error
text, file modes and exit codes are unchanged.

* docs: record EKS konnectivity cert move

* refactor: move EKS token webhook to the EKS agent tree

cmd/eks-token-webhook keeps the -addr flag, environment-derived
config, logging setup and exits; agents/eks/tokenwebhook owns Config
and Run. The handlers/eks TokenReview result type stays as recorded
temporary debt.

* docs: record EKS token webhook move

* refactor: move ECS agent runtime and credentials packages to the ECS agent tree

* docs: record ECS agent subpackage move

* refactor: move ECS agent implementation to the ECS agent tree

cmd/ecs-agent keeps process lifecycle: signal context, the separate New
and Run calls, both failure log lines, the exit and the ldflags-set
build version, now passed in through Config.AgentVersion.
agents/ecs/agent owns Config, LoadConfig and the agent.

* docs: record ECS agent move

* refactor: move RDS guest agent to agents/rds/agent

* docs: record RDS guest agent move

* refactor: move installer packages to operator/installer

* docs: record installer move

* refactor: move spx command tree to operator/cli

Moving the command tree out of cmd/ brings it under errcheck and gosec.
Flag and config wiring now fails loudly instead of silently dropping a
binding, listing commands fail when they cannot write their table, and
the formation server's unauthenticated TLS is annotated as a known gap.

* docs: record spx command tree move

* chore: accept known vulnerabilities with an expiry

The vulnerability scan failed preflight on a containerd advisory that dev
already carries and that is deferred to a separate dependency update. The
gate now passes only reachable findings listed with an expiry date, fails
on any new one or on an expired acceptance, and warns when an acceptance
is no longer needed.

* test: characterize ECR control-plane dispatch before registration seam

* feat: add AWS ingress service registration contract

* docs: record ingress registration phases 0 and 1

* refactor: route registered AWS services through the ingress dispatch registry

The gateway now consumes ingress/aws/dispatch. A registered service is
accepted by the auth gate, resolves its own action label, renders errors in
its declared envelope and is dispatched with an authenticated Invocation
(account, region, policy authorisation and a lazy verified actor). Every
other service keeps the existing switch, now named as the legacy path.

The awsgw role wires an empty registry and refuses to start if a registered
name is also served by the legacy table. No service is registered yet, so
behaviour for every existing service is unchanged.

* docs: record ingress dispatch registry consumption

* refactor: register the ECR control plane from its domain

domains/ecr/awsapi now registers the "ecr" AWS JSON 1.1 surface with the
ingress dispatch registry: action resolution, resource scope, authorisation
through the invocation, the composed capabilities and the success writer all
live with the domain. The awsgw role is the only serving composition point;
the gateway no longer imports the ECR API package and ECR leaves the legacy
service table, JSON error table and dispatch switch. The OCI /v2 route is
unchanged.

Operation coverage reads ECR's declared inventory, which the registration
uses verbatim; coverage.json is byte-identical.

* docs: record ECR control-plane registration

* fix: compose the ECR control plane in the integration harness

The harness stopped wiring ECR's composed capabilities when the
authorization-token action was composed, so every integration test that
creates a repository or mints a token got ServerInternal. It now composes
ECR as the awsgw role does, sharing the OCI registry, meta store and token
issuer the /v2 data plane uses.

* docs: record ingress pipeline deferral

* refactor: extract AWS error envelope rendering to ingress

ingress/aws/envelope owns the EC2, IAM-style and S3 XML error envelopes, the
AWS JSON 1.1 error body and X-Amzn-Errortype value, the JSON-protocol header
detector and the two error content types. Each shape keeps its own builder.

The gateway error writers, ErrorHandler and the legacy per-service envelope
selection stay in gateway and call the new package; gateway/eks renders its
JSON errors through it directly. A 140-case status/header/body golden
comparison across services and error writers was identical before and after.

* docs: record error envelope extraction

* refactor: move AWS service selection into ingress dispatch

Selector answers served, action, error protocol, registered entry and
startup overlap. The gateway supplies its legacy tables through the
dispatch.Legacy interface; legacy dispatch and invocation building stay
in gateway.

* docs: record ingress service selection move

* test: characterize ACM control-plane dispatch before registration

Pins full-pipeline error envelopes, a successful action, target parsing
agreement between dispatch and telemetry, authorization before the NATS
call, 413 and 503 paths, throttle/trace/audit action and the inventory.

* refactor: register ACM control plane from its domain

domains/acm/awsapi registers the acm JSON 1.1 surface through the
ingress dispatch registry, wired by the awsgw role. The gateway drops
ACM_Request, the ACM action table and every legacy acm entry; the
import invariant now covers each registered domain.

* docs: record ACM registration

* docs: record ECS, EKS and RDS source inventory and first-resource ranking

* docs: record EKS control-plane secrets persisted in the cluster record

* chore: drop containerd advisory acceptance now that dev ships v2.4.1

* test: characterize RDS DB subnet group lifecycle before extraction

* docs: record RDS DB subnet group lifecycle contract

* refactor: extract the RDS DB subnet group lifecycle owner

domains/rds/subnetgroup owns the db-subnet-groups/{name} record, member
subnet validation and the delete in-use guard. handlers/rds keeps AWS
validation, projection and paging and binds two consumer-owned
capabilities: the owner's Dependants (instances naming the group) and the
instance side's subnetGroupPlacement. Stored shape and behaviour are
unchanged.

* docs: record RDS DB subnet group owner extraction

* docs: correct RDS subnet group tagging debt and conformance scope

* test: characterize ECS task definition lifecycle before extraction

* docs: record ECS task definition lifecycle contract

* refactor: extract ECS task definition owner into domains/ecs/taskdefinition

Move the task definition record, container types, keys, reference parsing,
ARN helpers and the register/deregister/resolve/list logic into a resource
owner package. Stored JSON field names and KV keys are unchanged, and
revision allocation keeps its existing non-atomic read-then-write.

The owner declares its own PortMapping and SystemControl persisted types so
it no longer depends on handlers/ecs/bus; the handler translates them onto
the assign payload. Task and service launches reach task definitions only
through a launch-side taskDefinitionResolver. AWS conversion, the guest
projection and tags stay in handlers/ecs, and gateway authz only switches to
the moved reference/ARN helpers.

List handlers/ecs and the new package under spinifex_daemon so ECS-only
changes select e2e-ecs.

* docs: record ECS task definition owner extraction

* test: characterize EKS access entry lifecycle before extraction

* docs: record EKS access entry lifecycle contract

* refactor: extract EKS access entry owner into domains/eks/access

Move the access entry record, associated policy and scope types, keys,
PrincipalARNHash, the policy catalogue and group mapping into a resource
owner package. Stored JSON field names and KV keys are unchanged.

Owner is the only writer: Create, SeedCreatorAdmin, Update, Associate,
Disassociate and Delete carry the existing logic verbatim, and the put,
compare-and-set and delete primitives are private. The handler keeps AWS
validation, the cluster existence check, error mapping and projection.
Token review still reads records through the exported Get, and the cluster
prefix purge still sweeps entry keys.

List handlers/eks and the new package under spinifex_daemon so EKS-only
changes select the EKS suites.

* docs: record EKS access entry owner extraction

* test: characterize RDS engine catalogue before extraction

* fix: return InvalidParameterValue for a missing RDS master password

ValidateMasterUserPassword built the empty-password error with a bare
errors.New carrying the code only in its text, which awserrors does not
resolve, so CreateDBInstance without MasterUserPassword returned HTTP 500
ServerInternal. Build it with awserrors.Errorf like the other branches so
the gateway returns 400 InvalidParameterValue, and cover the full gateway
to RDS service path with a regression test.

* docs: record RDS engine catalogue boundary and evidence

* refactor: extract RDS engine catalogue into domains/rds/engine

Move engine identity and validation, the per-engine parameter catalogues,
effective-parameter resolution, db.* instance classes and engine/orderable
selection into an engine package. Behaviour, error codes and ordering are
unchanged.

The package imports no EC2 package: instance-class memory comes from an
immutable Sizing value built from an engine-declared InstanceTypes
interface, backed by the fixed instance-type table in handlers/rds.
Effective parameters leave as an engine-owned Setting, converted to
Parameter in handlers/rds. AWS output building, paging, apply-method
mapping, storage limits and the gateway runnable check stay in the
adapter path.

The RDS agent declares its own EngineCatalog interface and types and
receives an engine-backed implementation from cmd/rds-agent, so agent
code does not import the catalogue. Cross-engine tests use the two real
engines instead of a registered fake.

* docs: record RDS engine catalogue owner move

* test: characterize RDS DB parameter group lifecycle before extraction

* docs: record RDS DB parameter group lifecycle contract

* refactor: extract RDS DB parameter group owner

Move the parameter group and override records, keys and listing into
domains/rds/parametergroup behind an Owner. Delete asks an owner-declared
Dependants interface; instance-side resolution reads through its own
parameterGroupValues interface. SetOverrides refuses an unknown group so
no override key is written without its group. Stored shape, keys, public
errors and propagation are unchanged.

* docs: record RDS DB parameter group owner extraction

* test: characterize EKS add-on lifecycle and guest wire

Pin the persisted record and manifest layout, create/update/delete and
status-report transitions, the ignored client token and report version,
the missing serviceAccountRoleArn PassRole check, and the exact internal
add-ons HTTP body and agent TSV output as they stand today.

* docs: record EKS add-on lifecycle contract

* fix: require iam:PassRole for EKS add-on service account role

CreateAddon and UpdateAddon now pass serviceAccountRoleArn through the
existing EKS PassedRoleARNs path, so the caller needs iam:PassRole on the
role for eks.amazonaws.com, matching CreateCluster and CreateNodegroup.

* docs: record EKS add-on PassRole check

* refactor: extract EKS add-on owner

Move the add-on catalogue, record and manifest keys, CAS, status
transitions and staging into domains/eks/addon behind an Owner that is
the sole writer. The handler keeps AWS validation, error mapping and
projection; the cluster reconciler delegates reports through the narrow
addonReports interface; node groups call EnsureGPUDevicePlugin. Stored
keys, JSON shape, wire types and lifecycle behaviour are unchanged.

* docs: record EKS add-on owner extraction

* refactor: extract EKS add-on guest wire contract

Move the add-on status subject, delivery phase, status report, staged
manifest and internal add-ons response into contracts/eks/v1 and use it
from the handler, gateway and gatewayfetch, replacing the agent's
duplicate. Wire bytes are unchanged, including the internal add-ons body
that the SDK renderer emits with Go field names; compatibility tests pin
the JSON, the guest printf form and the TSV.

* docs: record EKS add-on wire contract extraction

* docs: update EKS add-on inventory and remaining edges

* docs: draft EKS add-on lifecycle correction design for review

* chore: run contracts tests in the default test, coverage and race targets

* docs: apply review decisions to EKS add-on lifecycle design

* test: characterize EKS add-on v1 compatibility with added fields

Pin which owner writes drop unknown record and manifest fields, that
reads and deletes ignore or erase them, that one undecodable entry fails
a listing, and that v1 wire consumers ignore extra fields.

* docs: add EKS add-on executor, bundle, v1 compatibility and release inventories

* docs: qualify historical architecture references

* docs: apply review decisions and ADR-0006 to EKS add-on v2 design

* fix(eks): bind internal report publishing to the caller's cluster

PublishInternal was authorised by IAM policy alone, with its resource
built from the body accountId and the URL cluster. The control-plane
role grants it on "*", so any control-plane VM session, any tenant
holding eks:*, or static system credentials could publish cluster
state, bootstrap and add-on reports for another cluster or account.

PublishInternal now passes the existing internal-route gate: the caller
must be a control-plane instance-role session that is a member of the
URL cluster in the body account. The gate and the handler decode the
body through one shared decoder, so the account checked is the account
the subject is built from. Every unauthorised target returns the same
AccessDenied, and invalid account or cluster names are treated as not
found. Valid publishes keep their subjects and payload bytes.

* fix(eks): bind webhook token review to the caller's cluster

WebhookTokenReview took its account from the request body and was
authorised by IAM policy alone, with the control-plane role granting it
on "*". A control-plane VM, any tenant holding eks:*, or static system
credentials could resolve a token against another cluster or account
and learn the Kubernetes groups it maps to there. Error responses also
distinguished absent accounts from absent clusters.

WebhookTokenReview now passes the same internal-route gate as
PublishInternal: a control-plane instance-role session that is a member
of the URL cluster in the body account. The gate and the handler share
one body decoder, each body-scoped internal route must declare its
reader, and every unauthorised target returns the same AccessDenied
without reaching STS verification. Same-cluster responses are unchanged.

* fix(eks): validate add-on serviceAccountRoleArn syntax

CreateAddon and UpdateAddon stored serviceAccountRoleArn without
checking it was an ARN, and the guest renders the value into the
add-on's manifests. A non-empty value must now be syntactically an IAM
role ARN (12-digit account, no region, role resource, IAM name and path
rules); anything else returns InvalidParameterException before any
record is written or manifest staged.

The syntax check is foundation/aws/arn.ValidateRoleARN. iam:PassRole at
the gateway remains the permission and existence check. Stored values
are not rewritten, and an UpdateAddon that omits the field still
succeeds on a record holding a legacy value.

* docs: record EKS internal-route and role-ARN security corrections

* docs: add EKS add-on release membership and activation case study

* fix: point UI build, CI and lint rules at moved package paths

* docs: record EKS add-on activation review decisions

* refactor: move quota admission to domains/admission/quota

Relocate the quota service, live counters and vCPU records from
handlers/quota to domains/admission/quota. Package renamed from
handlers_quota to quota; callers with a local quota identifier import it
as admissionquota. KV buckets, subjects and error codes are unchanged, and
the package's existing debt edges move with it unchanged.

* docs: reconcile package-boundary record for ADR-0001 close-out

Add the missing slice rows (the commits that dissolved spinifex/types, the
ECR repository projection, the stale-path fix and the quota move), correct
stale entries, record the dependency-rule breaks found in the import graph
with removal conditions, add the close-out table of remaining legacy paths
with their decided target owners, recount the mulga-side follow-ups, and
fix stale old-path references in docs and comments.

* test: move KV migration engine tests to foundation/state/migrate

The Registry and RunKV tests exercise foundation/state/migrate exclusively
but lived in spinifex/migrate's test file. Relocate them, with their NATS
helpers, to the package that owns the engine. No test name, assertion or
behaviour changes.

* refactor: move config and object-store upgrade workflow to operator/upgrade

Relocate spinifex/migrate, the operator-driven config-file and object-store
upgrade workflow behind spx admin upgrade, to operator/upgrade. Package
renamed to upgrade (imported as opupgrade where a local upgrade identifier
exists). It stays distinct from foundation/state/migrate, the generic KV
migration engine; no registry types, migration names, versions, file
formats or command names change.

* docs: record migrate move to operator/upgrade

* test: enforce ADR-0001 layering with a blocking ratchet

Add spinifex/architecture/layering, a test-only package that parses the
module's import graph, maps every production package to an ADR-0001
layer and checks each dependency rule as its own subtest. Existing
violations are allow-listed against their recorded debt; a new forbidden
edge, an unmapped package, a stale allowlist entry or a new package
under a frozen legacy root fails local preflight and CI.

Record the nine edges the test found missing from the migration record
(quota -> EC2 instance types, STS/Ochre/ELBv2 -> IAM, ELBv2
cross-domain, installer UI -> admin), name the importers of the utils
residuals and gateway/ec2_idempotency.go, and correct the handlers/iam
consumer list.

* refactor: drop the legacy handlers_ecr import alias

Import domains/ecr under its package name, or as ecrdomain where the
file also imports the AWS SDK ecr package, matching acmdomain. Also fix
a stale daemon file reference in the integration ECR daemon comment.

* chore: mark spf13/pflag as a direct dependency

operator/cli/wiring.go imports pflag directly. Same version; no upgrade.

* docs: record test-package-check and nilaway as unverified gates

* refactor: move the layering test to module-root architecture/

The ADR-0001 layering ratchet is repository governance tooling, not
Spinifex product code, so it sits beside tests/ rather than under the
spinifex/ product tree. make test, test-cover and test-race now include
./architecture/..., and the graph walk excludes architecture/.

* fix: update paths left stale by the package moves

The MariaDB image stamp test read the RDS engine from
handlers/rds/engine_mariadb.go, so test-images failed in CI; it now reads
domains/rds/engine/mariadb.go. Comments citing moved files now name
their new locations.

* refactor: move the default-VPC subject into contracts/ec2/v1

utils.SubjectEnsureDefaultVpc becomes ec2v1.EnsureDefaultVpcSubject, the
request/reply route between gateway account creation and the daemon.
Only the subject moves; the request and reply bodies are still anonymous
structs on each side and are recorded as such in the contract README.
The layering freeze now allows two utils files.

* docs: qualify the migrate split and record admin and Viperblock findings

The migrate row is a split, not an exact ADR-0001 map row, and needs a map
clarification. Correct the stale admin consumers, record the operator-only
admin files as movable, the vbwire prerequisite for the Viperblock adapter
and the capability decision encryption.go needs.

* refactor: move operator-only admin code to operator/admin

Config generation, certificate issuance, host discovery, telemetry,
email validation and image import/removal/orphan-volume tooling move
to operator/admin. Legacy admin keeps only the symbols with
non-operator consumers: default account identifiers, AWS credential
generators and system image promotion.

foundation/pki and the tenant ACM CA are unchanged. The readAMI
helper and the removal test fixtures are duplicated privately in
legacy admin rather than shared across the split. The now-stale
operator/installer/ui -> admin layering allowlist entry is removed.

* docs: record operator/admin split in package-boundary migration

* test: pin viperblockd fence, abandon and dirty-marker wire shapes

Characterization tests against the current vbwire package, before it
moves to contracts/viperblockd/legacy/v1: both subject forms for the
fenced and abandon routes, golden JSON for VolumeFencedEvent,
VolumeAbandonRequest, VolumeAbandonResponse and DirtyRecord, the dirty
bucket name, and the volume-key pattern shared by the lease and dirty
stores.

* refactor: move viperblockd fence, abandon and dirty-marker vocabulary to contracts

Move the fence and abandon subjects/DTOs, the dirty bucket name,
DirtyRecord and the shared volume-key pattern out of vbwire and into
contracts/viperblockd/legacy/v1, alongside the package's existing
mount/unmount/delete/sync/config-update routes. vbwire keeps only the
I/O helpers (BindDirtyBucket, ListUnsealedVolumes), now built on the
contract vocabulary instead of defining it.

Record the approved dirty-marker ownership boundary in the contract
README: the Viperblock adapter is the sole producer, viperblockd was
only its transitional custodian. Document the fence and abandon routes
and the dirty bucket in docs/service-interfaces.yaml.

* refactor: split the Viperblock EBS adapter out of services/viperblockd

Move the EBS provider adapter (volume lease, fence, dirty marker,
nbdkit recovery, provider handlers, encryption key loading) to
providers/ebs/viperblock. services/viperblockd keeps only process
lifecycle and the NATS subscription wiring that starts and stops it.

The dirty-bucket read path moves to providers/ebs/viperblock/dirty as
a read-only ListUnsealedVolumes capability; the adapter's write, clear
and purge logic stays unexported in the adapter package. Delete
services/viperblockd/vbwire now that its vocabulary lives in
contracts/viperblockd/legacy/v1 and its I/O helpers live in dirty.

Update operator/cli, the runtime service registry, qemunbdd's config
comment and the integration test harness to the new import paths, and
drop the now-stale architecture/layering allowlist and frozen-package
entries for the deleted package. Behaviour, persisted keys and NATS
subjects are unchanged.

* refactor: move the viperblockd role to runtime/roles/viperblockd

With the EBS adapter in providers/ebs/viperblock, services/viperblockd
holds only role supervision and the opt-in live data-path tests, so it
joins the other runtime roles. It was the last package under services/;
the frozen legacy list drops it.

* docs: record viperblockd contract, adapter and role moves

* test: characterise vpc.* network-realisation routes

Pin every vpc.* subject, JSON payload shape and the request/reply
{success,error} ack envelope exactly as they exist today, ahead of
introducing contracts/network/v1. Covers the 22 subjects registered
by domains/network/subscribers, the vpc.igw-attach/detach subjects
and InternetGatewayEvent already owned by contracts/ec2/v1, the
utils.AddNAT/PublishNATEvent client wire behaviour including the
delete-nat retry-on-ErrNoResponders budget, and the EC2-side NATEvent
and SGEvent/SGRule duplicates in domains/ec2/vpc.

Also adds the six vpc.* route-table and system-egress subjects that
were missing from service-interfaces.yaml despite being live
production routes (vpc.add/delete-igw-route, vpc.gate/ungate-subnet-
egress, vpc.add/delete-system-egress).

* feat: add contracts/network/v1 for vpc.* realisation routes

Declare the versioned wire vocabulary for the vpc.* control-plane-to-
network-realisation boundary: subjects, payload types, the shared
{success,error} ack envelope and the vpcd-workers queue group, one
file per route family. No NATS I/O, no consumer switched over yet;
the package coexists with the fragmented originals pinned in the
prior characterization commit until slice 3 migrates call sites.

* refactor: use contracts/network/v1 for vpc.* producers and consumers

Switch every vpc.* producer (domains/ec2/vpc, eip, instance, natgw,
routetable, igw, handlers/elbv2, handlers/eks, daemon, systemvpc) and the
network/subscribers consumer onto contracts/network/v1 subjects, event
types and the shared AckEnvelope. contracts/network/v1 becomes the sole
owner of vpc.igw-attach/detach, replacing the duplicate definitions in
contracts/ec2/v1.

Deletes the duplicated local subject constants and event structs:
subscribers' Topic* consts and event structs, vpc.NATEvent and SGEvent,
eip's natEvent, natgw's natGatewayEvent, and eks's systemEgressEvent.
domains/ec2/vpc.SGRule survives because EC2 persists it directly in
SecurityGroupRecord; contracts/network/v1.SecurityGroupRule was expanded
in slice 2 to match it field-for-field so wire bytes are unchanged.

No lifecycle or reliability changes: the NAT add barrier, delete
retry-on-ErrNoResponders, and the inconsistent per-call-site NAT
delivery modes (EIP AssociateAddress and DeleteNetworkInterface both stay
fire-and-forget with no ack) are preserved exactly, as are the golden
wire literals pinned in the characterization tests.

* refactor: replace utils/vpcd_event.go with a typed network projection client

Every vpc.* call site now goes through domains/network/projection's
operation-specific methods instead of utils.AddNAT, utils.PublishNATEvent
or utils.RequestEvent, so no caller passes a bare subject string. Each
method states today's delivery mode by name: AddNAT stays strict,
AddNATBestEffort and AnnounceNATAdd/AnnounceNATDelete keep the gaps those
call sites already had, and RemoveNAT keeps the ErrNoResponders retry.

utils/vpcd_event.go and its tests are deleted; the behaviour they pinned
(wire shape, ack envelope, retry-on-no-responders) moved into the
projection package's own golden and nat tests, unchanged. utils/ now
holds only encryption.go, which this does not touch.

* refactor: route the remaining fire-and-forget vpc.* producers through projection

CreateVPC/DeleteVPC, CreateSubnet/DeleteSubnet, AttachInternetGateway/
DetachInternetGateway, AddNATGateway/RemoveNATGateway, AddIGWRoute/
RemoveIGWRoute, GateSubnetEgress/UngateSubnetEgress and RemoveSystemEgress
were still publishing through natsmsg.PublishEvent or a raw nc.Publish
call with a bare subject string, left over from the mechanical slice 3
pass. Each now goes through its named projection.Client method instead,
so every vpc.* producer in the tree uses the typed client.

* refactor: move EBS encryption posture to domains/ec2/ebs/encryption and delete utils

The master-key loader was used only by EC2 image, instance and volume to
derive the AWS-visible Encrypted flag. It becomes ebsencryption.Enabled,
EC2's temporary reading of the provider's key-file setting; the cache,
empty-path meaning, error text and each caller's error handling are
unchanged (image still reports unencrypted when the key will not load).
Its successor is a providers/ebs capability reporting volume encryption
posture.

utils/ is now empty and deleted. The layering test drops utils and
services from the legacy roots, removes their allowlist entries and fails
if either retired root regains files. The S7 subject scan follows the
vpc.* literals from utils to contracts/network so its gap list stays
complete.

* docs: record the network contract, projection client and utils removal

* test: characterise instance-state persistence, recovery and generation handling

Pin the current local-file bytes and schema failure modes, the instance
bucket configuration, record key and wire form, the bucket version gate,
generation preservation across every KV writer and the VM conversion, and
what a returning node does for a missing, foreign, terminal or unreadable
canonical record. These describe current behaviour, not the ADR-0007 target.

* test: freeze direct instance-state consumers

Add an AST ratchet over production code that fails when a new file names
the daemon's instance-state bucket, record keys, local-file API, the raw
vm.InstanceRecord or its conversion, or a JetStreamManager instance-state
method. Today's 73 uses form a shrink-only allowlist keyed to the slice 0
inventory; stale entries fail, and a synthetic-source self-test proves the
matcher detects each kind of use and ignores declarations.

* docs: record ADR-0007 slice 0 instance-state inventory

Record the instance-state persistence formats, the nineteen direct
consumers by process and access kind, the characterised recovery and
schema outcomes, the generation-preservation matrix and the ratchet that
freezes the consumer set. Nothing conforms to ADR-0007 yet and vpcd stays
blocked.

* test: narrow the instance-state ratchet to instance-state access

Stop freezing the JetStreamManager type and constructor, which also serve
cluster state; flag only instance-state methods, bucket and key identifiers,
record codecs and local-state access. The cluster-state-only consumers in
daemon_mgmt_ip.go and operator/cli/cluster.go leave the allowlist (73 to 67).
The self-test now proves a cluster-state use is ignored and an instance-state
method call is caught. Record the owner's disposition of the KV-unavailable
restore result in the migration record.

* docs: record the narrowed instance-state ratchet commit

* docs: design the instance-state transition record and activation gate

* docs: record the instance-state transition-record design commit

* docs: record slice 1a activation-gate decisions

* feat: add instance transition-record codec with format marker

Adds DecodeTransitionRecord and TransitionRecord.Encode in the record's owner
package. A top-level format member selects the shape: absent or 1 decodes the
legacy record and is never given a marker on write; 2 also decodes the new
assignment and observation sections; an integer above 2 decodes its legacy
fields read-only and Encode refuses it; anything else is refused on decode.

Encode applies only the typed paths that differ from the decode-time snapshot
onto the input, so unknown members at every object level and unchanged known
fields keep their read form. A changed array is replaced whole. Decode refuses
malformed JSON, duplicate keys at any depth, keys that alias a known field by
case, trailing data and a non-object record, each with its own sentinel.

No production reader or writer uses the codec yet; the new types are not
part of vm.InstanceRecord, so every existing record encodes unchanged. The
codec file is registered as an owner file of the instance-state ratchet.

* docs: record slice 1b step 1 codec and awsgw rollout qualification

Records the codec added in e62f921d2 as design Section 10 (C1 to C7): its
surface, preservation at every object level, the changed-array limitation,
marker handling, the rejection classes and its capable-writers-only scope. C2
supersedes P1's top-level-only preservation for the codec. G19 records that
old read-only gateway consumers remain safe but DescribeInstanceStatus gains
unconfirmed/degraded visibility only after awsgw upgrades. The migration record
gains the commit row and states that no production path uses the codec yet.

* refactor: move the instance transition-record codec to domains/ec2/instance/state

The codec defines how the canonical persisted instance record evolves, with
its assignment and observation sections, which is EC2 instance ownership rather
than node-local VM supervision. It moves unchanged into its own package and
keeps wrapping the legacy vm.InstanceRecord alias and its spec and status
types, which stay in runtime/compute/vm for now.

The domain-to-runtime import is recorded as new dependency-rule debt with its
removal condition and allow-listed against that entry. The instance-state
ratchet now names the new file as an owner file; its allowlist is unchanged.

* fix: refuse array changes that would drop element extensions

A changed array is replaced whole by the writer's value, which silently lost
any member a newer writer had added inside its elements. Encode now inspects
the array as read: if any element carries a member its typed schema does not
know, at any depth, it returns ErrRecordExtensionConflict naming the array and
the first such member. Arrays without such members are still replaced whole,
unchanged arrays are still kept verbatim, and arrays inside unknown members are
never inspected.

* docs: record the codec move and the array extension-conflict rule

Records 8db9771fb and c617914a1. T1 and Section 10 now name
domains/ec2/instance/state as the eventual owner of the persisted instance
record and its evolution, with vm.InstanceRecord as the temporary legacy type
it wraps. C3 replaces the changed-array limitation with the refusal: a changed
array with element extensions fails with ErrRecordExtensionConflict and is never
silently dropped. P2 stays a conservative rule until finalisation.

* fix: refuse removals that would drop record extension fields

A capable writer may no longer remove or replace a known object, map entry or
array when its stored value carries members the writer's schema does not know.
The check that guarded changed arrays now runs wherever the merge drops or
overwrites a stored value instead of merging into it: a known member deleted or
set to null, a map entry removed or stored under a key the typed decode
rewrote, a value of another JSON kind, and a changed array. Encode returns
ErrRecordExtensionConflict naming the changed container and the first unknown
member. Removal stays allowed when the stored value has no extensions, and a
change merged member by member still keeps unknown members.

* docs: record the uniform extension-conflict rule

Adds design clause C8 for 0d7b4266d: a capable writer may not remove or
replace a known object, map entry or array whose stored value carries unknown
structured extension fields; removal without extensions stays allowed. C3 and
C5 point at it. The migration record gains the commit row, updated subsection
wording and a pointer-bump follow-up deferring make docs-portal to the Mulga
gitlink PR so the portal evaluates the proposed Spinifex revision.

* refactor: inject vpcd's IMDS instance-state readers from the instance state boundary

* docs: cite the vpcd reader injection commit in the migration record

* refactor: move vpcd to runtime/roles/vpcd

* docs: cite the vpcd move commit in the migration record

* refactor: move the ECS agent wire vocabulary to contracts/ecs/v1

Move handlers/ecs/bus to contracts/ecs/v1 (package ecsv1) with no legacy
shim. Subject strings, JSON fields and types are byte-identical; the old-agent
compatibility test moves unchanged and golden pins cover the remaining
message types. The README route table records that only service-reconcile
has a live producer today; the agent reuses these payload types through the
gateway actions. service-interfaces.yaml lists ecs.bus.* under the daemon.

* refactor: move system-image promotion to domains/ec2/image

Move images_promote.go and its tests from admin to domains/ec2/image:
SystemOwnerAlias, PromoteImageOpts/PromoteImageResult, PromoteSystemImage,
GetAMIMetadata and the private snapshot reader. Storage, ordering, errors and
promotion behaviour are unchanged; the daemon, gateway/spx and operator CLI
callers import ec2image. admin now holds only account IDs and key generators.

* docs: record the ECS contract and image-promotion moves and the remaining-roots matrix

* refactor: move the bootstrap account identifiers to foundation/aws/identifiers

DefaultAccountID and DefaultAccountName join GlobalAccountID as the fixed,
platform-reserved identity of the first human-facing bootstrap account.
Names and values are unchanged and stay fixed. Callers in daemon, gateway,
awsgw, accountteardown and the operator CLI use awsidentifiers; admin now
holds only the IAM credential generators.

* docs: cite the bootstrap account identifier move in the migration record

* refactor: inject the STS cluster JWKS lookup from handlers/eks

handlers/sts declares ClusterJWKSResolver and keeps JWKS decoding and
InvalidIdentityToken mapping; handlers/eks implements it as
OIDCJWKSReader beside the bucket and key layout helpers. awsgw and the
integration harness inject the reader. STS no longer imports any EKS
package, including tests, and the handlers/sts -> handlers/eks layering
exception is removed.

* docs: cite the STS JWKS resolver cut in the migration record

* refactor: move the AWS credential-format generators to foundation/aws/credentials and retire admin

GenerateAWSAccessKey and GenerateAWSSecretKey move unchanged to
foundation/aws/credentials as a stateless format primitive. handlers/iam
and operator/cli import it directly. The admin legacy root is deleted
and joins the retired roots so it cannot return.

* docs: cite the admin retirement in the migration record

* revert: remove the uncalled ADR-0007 codec and design stack from the ADR-0001 checkpoint

The instance transition-record codec, its tests and the slice 1a design
had no production caller. They leave this package-boundary checkpoint
and will be reapplied on a dedicated ADR-0007 branch. Slice 0
characterisation and the vpcd IMDS readers in
domains/ec2/instance/state stay.

* docs: cite the ADR-0007 codec revert in the migration record

* fix: declare the ECS action subjects in service-interfaces.yaml

Declaring ecs.bus.* made ecs a managed prefix for manifest-lint, which then
failed on the 34 ECS action subjects the daemon registers. Declare them as
ecs.*, the same wildcard convention as rds.*.

* chore: run manifest-check and manifest-lint in preflight

CI runs both, but preflight did not, so manifest drift could pass local
checks and still fail Build and Test.

* docs: record resumed preflight enforcement and dev merge ports

* fix: restore dev changes dropped by earlier merges

Reapplies the slices.ContainsFunc rewrite in nodeFitsCustomerInstance and the DeleteDBSubnetGroup doc comment, both lost when their files were refactored.

* docs: record accountteardown as a frozen legacy root pending cleanup capabilities

Ben Duncan 021f439bab feat: recover instances automatically from a node that stopped heartbeating (#1111)
* feat: recover instances automatically from a node that stopped heartbeating

A node that dies hard takes its guests with it, and nothing brings them back
until an operator brings that node back. Every daemon now runs the same small
reconciler: it reads the instance records, selects desired-running instances
whose owner is stale, and relaunches them here.

The claim is a CAS on Status.LastNode and that is the whole of the
coordination. Several survivors race one instance, exactly one revision wins,
and the losers find a record naming a live owner and stop considering it. A
claimant that dies mid-launch leaves the record naming a node that is itself
stale, which is the same candidate the next pass derives again, so there is no
lease to expire and nothing to reconcile by hand.

Ownership is not permission to write. The volume leases still decide whether the
guest can move, and VolumeMounter.Mount runs before startQEMU, so an attempt
that loses the volume race has touched no tap, no OVS port and no OVN binding.

A storage failure is not a host failure and wants the opposite response. A guest
paused by werror=stop publishes Health.IOErrorSince, and a record carrying it is
refused: the volumes are the same objects in the same store from anywhere, so
relaunching moves the pause rather than ending it. A node whose own object store
is not answering stands down entirely, which separates a store broken here from
a store broken everywhere without either having to be diagnosed. A launch that
does not complete backs this node off that instance, doubling to a cap, because
nothing on the mount path can yet say which of the two it hit.

Recovery is off by default and inert below three nodes. It also waits until it
has seen its peers live, or five minutes, so the first node back from a
coordinated shutdown does not recover guests from nodes that are still booting.

* test: prove instance recovery moves a host failure and refuses a storage failure

The e2e half of automatic instance recovery, asserted from both sides because a reconciler that cannot tell the two failures apart passes one and fails the other. InstanceAutoRecovery takes a node down and requires the guest back on exactly one survivor, identified by the qemu process rather than by what the API reports. InstanceRecoveryRefusesStorageFault stops predastore cluster-wide first, so the guest is paused by werror=stop when its node goes away, and requires that nothing moves.

Also fixes the settle window, which re-evaluated every pass and so held a daemon back for its first five minutes over exactly the failure the reconciler exists to handle. It now latches once every peer has been seen live.

harness.InstanceHostingNodes replaces the single-node lookup so a caller can assert there is exactly one host rather than assume it, and skip a node it has deliberately taken down.

* fix: make automatic instance recovery a cluster-wide setting

Recovery was read from the per-node Config, so it had to be written three times on a three-node cluster, once inside each [nodes.<name>] table. A top-level [recovery] table — the obvious thing to write, and what the e2e suite writes — was parsed into nothing and the daemon reported recovery disabled on every node with the setting plainly in the file.

Cluster-wide is also the honest shape. A node with recovery off is not opting out of anything: recovery is what survivors do to a dead node's instances, so the setting belongs where there is one of it.

* test: drive real I/O into the storage-fault case, and freeze the store rather than stop it

Measured on a three-node cluster: predastore stopped cluster-wide for twelve minutes against idle guests paused none of them. Viperblock serves what it has cached and an idle guest issues nothing that reaches the object store, so the test asserted that nothing moved in a run where nothing was ever faulted.

The victim now launches with cloud-init user-data that writes to its root volume continuously. User-data rather than SSH because a routed-NAT cell gives guests no public address, so a test that had to log in could not run on half of them.

The fault is SIGSTOP rather than a unit stop, for the reason the storagefault suite already gives: a frozen process holds its connections open and answers nothing. Under that fault and that load the first BLOCK_IO_ERROR arrived 4m47s later, so the pause budget is now ten minutes rather than three.

* test: give instance recovery its own suite and its own nightly cell

Both tests take a node away and one of them freezes predastore cluster-wide, so anything sharing the environment reports that outage as its own failure — the same argument storagefault already makes for being its own package. They are also slow by nature: a dead owner has to be seen stale twice, a guest has to boot, and the storage case waits for a pause measured at 4m47s and then holds four minutes to prove nothing moved. Roughly twenty minutes on top of a permutation cell budgeted at thirty-five.

Cell 31 is three-node and static, matching storagefault's, with a 75-minute job budget over a 60-minute suite timeout. The suite is eligible on multi-node environments and deliberately not in the nightly permutation set.

* fix: give a guest long enough to open a volume the object store is slow to serve

QEMU opens every drive before its monitor answers a greeting, so the QMP
greeting deadline is really a deadline on opening the guest's volumes. At 30s
it was shorter than a cold viperblock open costs on a cluster that has lost a
node, where every object read is served degraded: measured at 35s with one node
of three away. The launch killed the guest five seconds short of ready and then
did it again on every retry, which is a recovery that can never complete.

A network-backed drive now gets its own deadline for the same reason VFIO
already had one — synchronous work before the monitor answers — and the
instancerecovery suite is what found it.

Also make the suite's predastore thaw best effort per node. It runs after a
node has been taken away, where there is no process to signal, and a node it
cannot reach must not stop it restoring the rest.

* docs: name the two newest cells in the dispatch input

The cells input is the operator's index of what a number means, and it stopped
at 29 while 30 and 31 were added.

* test: prove the guest is writing before freezing the store in the recovery suite

The storage-fault test froze the object store as soon as RunInstances reported
running, which is when QEMU has launched rather than when the guest has booted.
On the nightly cluster the freeze landed while the guest was still in UEFI, so
the only drive it could reach was the EFI varstore — and pflash has no
werror=stop to pause on, so the guest never paused and the test reported a
product failure it had caused itself.

The load driver now prints to the serial console after each pass it has written
and synced, and the test waits for that before freezing. The console is read
through GetConsoleOutput, so this still needs no login and still runs on cells
whose guests have no public address.

* feat: recover instances automatically with nothing to configure

The switch is gone. An instance whose host has failed is down whether or
not recovery is enabled, so the only outcome a disabled reconciler can
produce is leaving it down — which is the state recovery exists to end,
not a safer one to fall back to.

Against that, the switch cost a cluster that can be configured into
never recovering anything, with no symptom until a node dies. This
feature already hit that once: a top-level table parsed into nothing and
every node reported recovery off with the setting plainly in the file.

What makes recovery inert is now only facts about the cluster — no
cluster config, no JetStream, or fewer than three nodes — and each says
in the log which one applied. The e2e no longer writes config or
restarts daemons: it waits for every node to report the reconciler
active on a cluster nothing configured, so reintroducing a switch fails
there as well as in the unit tests.

* feat: stop retrying a recovery that is never going to work

Every failed attempt used to go to the same exponential backoff and stay
there. An instance nothing could launch was retried every fifteen
minutes forever, still observed-running on a node that is gone, with no
account of it anywhere the customer or an operator would look.

A failure is now classified and counted. Two classes are read from what
the launch actually reports: the node it was taken from still holds a
volume lease, which clears on that lease's clock and is retried on a
faster one, and this node has no room, which another survivor may. There
is no terminal class, because nothing on this path can prove one — the
launch collapses everything else into ServerInternal, so a verdict of
"never going to work" would be a guess, and the guess that abandons a
recoverable instance is the expensive one.

The budget bounds the unknown case instead. Every class counts against
it, since a class that did not would be the old unbounded retry under a
narrower condition. Exhausting it leaves the instance where AWS leaves
one whose host failed and could not be brought back: stopped, carrying a
StateReason that names the cause and the last error, one StartInstances
from running again. Writing the desired state down is also what makes
one node's decision cluster-wide, because selection reads desired state
— the same property the claim already has.

A record another node has since claimed is never touched, so a node
exhausting its attempts cannot stop a guest that is now running
elsewhere.

* fix: give a guest the time for every cost it pays before its monitor answers

A GPU instance booting from a network-backed root volume pays both
costs: QEMU opens every drive across the object store and then pins the
whole of guest RAM, one after the other, all before the monitor answers.
The deadline took whichever was larger, so such a guest was given less
time than it needs.

That the two floors are both 180s is why nothing has been seen yet — the
VFIO branch has always returned at least the network-drive deadline. It
is the same defect either way, and the symptom when it lands is a GPU
instance SIGKILLed on every attempt while its plain sibling launches,
which reads as a GPU fault rather than as a deadline.

The costs are now added, the plain QEMU startup is counted once rather
than replaced, and the cap covers both floors together so it cannot clip
a guest before either cost has been waited out.

* test: assert the AWS-visible arc of a host failure end to end

A customer cannot see which host an instance is on, and AWS never tells
them. What they can see is DescribeInstanceStatus, so that is where a
recovery has to be provable, and the suite never looked at it.

Three frames are now required, in order: running with system-status ok
before anything is broken, system-status impaired while the owning node
is gone, and ok again once a survivor is running it. The middle frame is
the one worth having — the window opens when the owner's heartbeat goes
stale, which is strictly before any survivor may claim, and closes when
the relaunch registers, so it is bounded rather than lucky. Reporting ok
throughout would be the more comfortable lie.

The availability zone is compared across the first and last frames as
well. A recovery that crossed one would break every placement promise
made to the customer, and nothing else in the suite would have noticed.

* test: prove a half-healthy node fences itself and is never a second writer

The two existing recovery cases take a node away by stopping its services,
which is the failure this feature handles least interestingly: a node that is
gone has no opinion about who owns its volumes. The one that matters is the node
that is still up, still running QEMU, still answering its own local clients, and
simply cannot reach consensus. That is the state in which two nodes can each
believe they own a volume, and the only thing between that and a corrupted disk
is that the partitioned node gives up first, on a clock it can evaluate without
reaching anything.

So this drops NATS on 4222 and 4248 between one node and its peers and nothing
else, then asserts the ordering the safety argument rests on rather than the
outcome it produces. A watch samples every node every three seconds for the
whole run, including the heal, and fails on any single sample naming two hosts.
Two guests writing one volume through one object store is data loss already
under way, not a race that resolves, and no point-in-time assertion can see one
that appeared between its own samples.

The injector takes its own nft table rather than touching inet spinifex_filter,
because a test that flushed the node's real firewall would leave it either
unfirewalled or misfirewalled with no sign of which, and a separate table at
priority -300 heals in one atomic delete. A transient systemd timer removes it
independently, so a cancelled workflow does not leave a node cut off from its
cluster until somebody notices. It proves SSH still works and proves a peer port
is genuinely unreachable before anything is asserted, since a rule set that
installed cleanly and dropped nothing would read as the system tolerating a
partition.

The suite budget goes to 90m and cell 31 to 105m to fit the third case.

* fix: move an instance's boot state, volumes, logical port and address with it

A record-driven launch assumes the node reading the record is the node that wrote
it. On a daemon restart that holds. On a recovery onto a survivor it does not, and
five things follow from it — one that stops a moved instance booting at all, and
four that stop it running anywhere.

A load balancer never comes back from a host failure. Its boot configuration is a
set of files under the runtime directory and the record holds their paths, so the
survivor restores paths that exist only on the node that died. The hook that
rebuilds them was reachable from Restore alone, and the cross-node path goes
straight to vmMgr.Run — so QEMU is handed a netcfg, an agent env and a CA cert
that are not there. The gateway URL baked into that env names the creating node's
management bridge as well, which the rebuild corrects because it rebuilds from
whichever node is running it. Firing the hook on both paths fixes both, and a
rebuild that fails now refuses the launch: a guest that boots without its network
configuration is worse than one that does not boot, because the records would say
it recovered.

The export outlives the guest and holds the volume lease. A returning node is
healthy, so it renews that lease indefinitely and the new owner never acquires:
the guest is stopped here and refused there, recovery spends its attempt budget on
a volume that was never going to be free, and gives up on an instance that was
never unrecoverable. So the export is given up too, over a new node-addressed
request that tears it down exactly as the fence does. Deliberately not an unmount
— an unmount seals, this node's block map is the stale one, and sealing publishes
it over the winner's. Unlike the fence it deletes the lease key rather than
leaving it to expire, because the lease is still this node's to hand back.

The tap outlives the guest, and the tap is what claims the instance's OVN logical
port. The binding names one chassis, so two nodes offering the same iface-id do
not split the traffic — they contend, and the address answers from whichever won
last. It also blocks the layer above: the external IP's host ingress is pruned on
the evidence that the owning guest sits on another chassis, and that stays false
while this node is still claiming the port.

The management address outlives the guest as a cluster-wide reservation, and the
release was unconditional. br-mgmt is one flat L2 segment, so the node an instance
left was freeing an address still in use and offering it to the next instance
anywhere. Only the node an entry names may release it now, with the takeover
recorded on arrival so the node actually running the instance can still give the
address back. An entry written before the node field existed names nobody and
stays releasable, because there is no other holder to collide with.

The fence path already cleaned up the tap, so the release fix repairs that path
too.

* test: prove a load balancer keeps its name, its address and its traffic when its host dies

Takes away the node running an internet-facing ALB and asserts the four things a
customer of one actually holds: the name keeps resolving, the address behind it
does not move, requests through the name are answered again without anybody being
called, and the backends are healthy again from the recovered load balancer's
point of view.

The backends are placed around the load balancer rather than beside it. A load
balancer lands wherever a node answers its queue group, so its node is discovered
and the backends are relaunched until both are elsewhere; one on the node about to
be taken away would be recovered too, and the run could not then tell an ALB that
came back serving from one that came back with nothing to serve.

DNS is asked of a node's own northstar over the wire, and the HTTP probes resolve
through the same server, so the claim under test is what this cluster answers for
a name rather than what the machine running the tests was configured to forward
to. A watch samples every surviving node every five seconds for the whole run,
because an answer that went missing or pointed elsewhere for one reconcile pass is
the outage, and no single sample reaches it.

The returning node then has to give up what it no longer owns: no second copy of
the guest, and no tap still claiming the load balancer's logical port, since OVN
binds a port to one chassis and a second claimant contends for it rather than
splitting the traffic. The last assertion is that the name still serves with that
node back in the cluster.

* docs: name the new cell in the nightly's cell list

* test: stop the disk-load guest from filling the console it is judged by

The load generator announced every write, once a second, for as long as the
test ran. The console is a ring buffer this suite reads back, so an hour of
that pushes out everything explaining a failure, including the kernel's own
account of the I/O error the test exists to produce. Announce twenty times,
then keep writing quietly.

* docs: say what the OCI guide has been proven on, and what a host failure does

The guide read as a support statement for OCI rather than as an account of one
tested path, promised seven steps and then gave eight, and said nothing about
what happens to a guest or its public address when the node under it fails.
State the evidence, state that the nightly guards the datapath and not the
cloud, and give the failure behaviour as a table with the reason codes a
customer will actually see.

Also say plainly what the volume lease is: one running guest and a bounded,
logged window, not a write barrier the object store enforces. Someone sizing a
workload against this should read that before they read the table.

* docs: say why the mount classifier refuses to retry a lease another node holds

It reads as an omission — a lease held elsewhere is the most transient refusal
there is. It is not. This classifier drives the restore path, where the holder
is a node that is running the guest, so retrying would relaunch against a live
owner. Recovery wants the opposite and reads the refusal itself.

* feat: claim a recovered guest's public address in line, and verify it arrived

A recovered instance was reported running before anything moved its public
address off the node that died, so for up to fifteen seconds the records said
recovered and the address answered nothing. The recovery path now runs the
affinity pass itself, which is idempotent and is the same pass the ticker runs.

Two things the pass could not do before. It abandoned every remaining address
on the first API failure, though a throttle or a denial is per-object and the
guests behind the others are just as dark. And it trusted the move's own
response, which is OCI agreeing to the request rather than OCI having done it,
so an accepted move that never landed read as success. It now re-reads what OCI
delivers here and reports the difference.

An address that will not arrive makes the guest a system-status failure with the
time it went dark, the same shape AWS uses for a host-level fault. The guest
passes every check it can be asked about itself, which is exactly why reporting
it healthy was the worst available answer.

* feat: give a recovery attempt one trace across all three of its phases

The volumes opening, QEMU starting and its monitor answering already trace
themselves, but nothing tied them to the attempt that asked for them: three
orphan traces per recovery, no way to ask which phase a slow one spent its time
in, and nothing naming the node the guest came from. A span over the attempt
makes them its children, and the reconciler's own log lines carry its trace ID
because the handler stamps it from the context.

A failed attempt records the fault and the attempt count on the span, so the
budget running out is readable as a sequence rather than as twelve unrelated
warnings.

* fix: finish a fence once its writer finally exits

A kill that did not take effect was logged, counted and dropped. The export
stayed registered and the lease stayed held, which is correct while the writer
lives and wrong forever after it dies: a lease a healthy node keeps renewing
never expires, so the volume could not start anywhere.

The failure is now re-reported every 30 s until it resolves, and the teardown
completes as soon as the writer is confirmed gone. Only a delivered kill is
waited on — a refused one says nothing about what became of the writer.

* test: stop judging a detached stop or terminate on a transient state

Both tests read the instance state immediately after the ack, but the transition
runs on its own goroutine, so the read races it in both directions: too early
sees running, too late sees the final state. The race gate caught the first of
those on a loaded runner.

* fix: replicate the volume lease and dirty buckets across the cluster

Both were created with the default single replica, so both lived on one node.
That node holds the answer to "who may write this volume" and the marker every
mount reads, and losing it takes volume leasing and mounting down cluster-wide.
A partitioned node was fenced correctly and then no survivor could relaunch its
guest: every attempt failed on "read dirty mark: no responders available", for
ten minutes, until the budget ran out.

The replica count is now the cluster's node count, as the gateway's own buckets
already do. Existing buckets are raised in place rather than requiring a wipe.

The e2e diagnostics that should have said this are fixed too. The fence and the
surrender are logged by the storage service, not the daemon, so the assertions
read the wrong journal; and Eventuallyf evaluates its message at the call site,
so a ten-minute wait was explained by a log that stopped before it began.
