spinifex/docs/PACKAGE_BOUNDARY_MIGRATION.md

Package-boundary migration record

Status: Active implementation record. Decision: Mulga ADR-0001 — Spinifex Package Boundary and Layout. Scope: Spinifex source layout only. This record does not establish a new architecture decision, expand a customer-facing interface, or claim that the current implementation conforms to the target layout.

Purpose

This document records the implementation sequence for ADR-0001 in this repository. The ADR owns the target layout and dependency rules; this record captures the source-level entry-point inventory and the evidence needed for each narrow structural slice.

The migration proceeds on one long-lived refactor branch. Each commit remains small, independently buildable and reviewable; that does not require one pull request per package move.

Baseline

The inventory below was taken from Spinifex commit ecef5e4d2f793b4cf2c96d0a43d0a1ab37be3eed, the revision pinned by Mulga when ADR-0001 was accepted. It records ownership standing, not a promise that a binary or script is AWS-compatible or supported beyond its documented scope.

Entry-point and automation inventory

Product operator and delivery entry points

Current path	Standing	Target ownership	Migration rule
cmd/spinifex (spx)	Supported operator process	Thin main; command assembly in spinifex/operator/cli and individual supported use cases in spinifex/operator/*	Preserve binary and supported command compatibility. The CLI must reach a domain through an explicit capability, never its private state.
cmd/installer	Delivery executable	Thin main; interactive, unattended and host-installation work in spinifex/operator/installer	Preserve installation behaviour while separating executable startup from delivery logic. It is not, merely by existing, the permanent administration interface.

cmd/spinifex/cmd and cmd/installer/* are presently implementation-bearing trees, not thin entry points. They are not moved until their individual receiving owners and test seams are selected.

Guest and named-role entry points

Current path	Standing	Target ownership	Evidence of role boundary
cmd/ecs-agent	ECS guest agent	Thin main; spinifex/agents/ecs	Baked into ECS node images; communicates with the control plane through the AWS gateway, not NATS.
cmd/rds-agent	RDS guest agent	Thin main; spinifex/agents/rds	Runs in an RDS guest, handles bootstrap and engine directives through the gateway.
cmd/lb-agent	ELBv2 guest agent	Thin main; spinifex/agents/elbv2	Included in the load-balancer microVM and controls its local data plane.
cmd/eks-token-webhook	EKS control-plane guest role	Thin main; spinifex/agents/eks/tokenwebhook	Baked into the EKS node image as the Kubernetes TokenReview webhook.
cmd/eks-gateway-fetch	EKS control-plane guest helper	Thin main; spinifex/agents/eks/gatewayfetch	Fetches recovery and addon state through the AWS gateway.
cmd/eks-gateway-publish	EKS control-plane guest helper	Thin main; spinifex/agents/eks/gatewaypublish	Relays bootstrap and state reports through the AWS gateway.
cmd/eks-webhook-cert	EKS image-resident certificate helper	Thin main; spinifex/agents/eks/webhookcert	Invoked by EKS image scripts to create/reuse webhook serving certificates.
cmd/eks-konnectivity-cert	EKS image-resident certificate helper	Thin main; spinifex/agents/eks/konnectivitycert	Invoked by EKS image scripts to create/reuse Konnectivity serving certificates.
cmd/ecr-credential-provider	EKS node integration	Thin main; spinifex/agents/eks/credentialprovider	Kubelet exec credential provider baked into EKS images; it is not ECR control-plane ownership.

No common agent package is introduced by this inventory. Shared mechanisms are considered only when the existing role and least-privilege boundaries remain intact; ADR-0001 explicitly defers that design.

Development and qualification entry points

Current path	Standing	Target ownership	Rule
cmd/aws-model-coverage	Qualification generator	Thin main; reusable code in internal/tooling	Produces the dispatch-versus-model inventory; never imported by product packages.
cmd/dhcptest	Development diagnostic	Thin main; reusable code in internal/tooling if extraction is useful	It is a DHCP probe, not a supported spx admin command.
cmd/spx-loadgen	Qualification/load tool	Thin main; reusable code in internal/testkit	It drives test load and is not shipped to nodes.
tests/e2e/*/cmd/*, tests/bench/*/cmd/*	Test and benchmark-private tools	Remain test-private	They are invoked by a test or benchmark harness, not a product process.
docs/terraform-workbooks/demo-app/main.go	Demonstration workload	Remain with the workbook	It is neither a Spinifex executable nor a product package.

Automation standing

Path class	Standing	Rule during migration
.github/scripts/	CI-private qualification automation	Keep at the module root; the invoking workflow owns the evidence scope.
build/, images/, scripts/images/, image build and publish scripts	Delivery and guest-image inputs	Keep at the module root. In-guest helpers stay with their image; do not relocate shell sources into Go packages.
scripts/setup.sh, setup-ovn.sh, install-node.sh, node-reset.sh, uninstall-spx.sh	Transitional delivery and documented host-operation mechanics	Keep at the module root. They may implement a published procedure but are not an enduring public administration API solely because they are installed on a node.
scripts/dev-env/, scripts/demo/, benchmarks, diagnostics and Terraform experiments	Development or exploratory automation	Keep at the module root; they are not customer-facing contracts.
scripts/check-coverage.sh, diff-coverage.sh, run-gate.sh, sync-aws-models.sh and test harness scripts	Repository and qualification automation	Keep at the module root; their caller defines the contract and evidence.

First source move — ARN

The first source move is the cohesive ARN leaf package:

• old import path: github.com/mulgadc/spinifex/spinifex/arn
• target import path: github.com/mulgadc/spinifex/spinifex/foundation/aws/arn

Source commit 91ac70e29 moves the ten package files and updates all forty-four Go importers. It changes no behaviour and leaves no forwarding package.

Verification passed with an isolated Go module/build cache:

• go test ./spinifex/foundation/aws/arn
• go test for the fourteen packages directly importing ARN
• a Go-source search for the old import path returned no matches
• git diff --check

The inventory was intentionally committed before this move so a later thin-main refactor cannot silently choose an owner by convenience.

Second source move — AWS filters

The second source move removes the generic filterutil location and name:

• old import path: github.com/mulgadc/spinifex/spinifex/filterutil
• target import path: github.com/mulgadc/spinifex/spinifex/foundation/aws/filters

Source commit e707be942 moves the two package files, renames the Go package to filters, and updates twenty-eight importing files. Callers use the explicit import alias awsfilters: many filter implementations already hold a local filters value, and the alias prevents a package-name collision without changing that local state or any filter behaviour.

Verification passed with an isolated Go module/build cache:

• go test ./spinifex/foundation/aws/filters
• go test for the seventeen direct caller packages
• a Go-source search for the old import path returned no matches
• git diff --check

Third source move — AWS Query parser

The third source move names the protocol concern rather than the first service that happened to use it:

• old import path: github.com/mulgadc/spinifex/spinifex/awsec2query
• target import path: github.com/mulgadc/spinifex/spinifex/ingress/aws/query

Source commit caaf98d9e moves the two parser files, renames the Go package to query, and updates thirteen importing files. The parser is used across EC2, IAM, STS, ECS, ECR, ELBv2 and RDS, but owns only AWS Query wire decoding and no service action or resource semantics.

Verification passed with an isolated Go module/build cache:

• go test ./spinifex/ingress/aws/query
• go test -run '^$' for six direct caller packages
• a Go-source search for the old import path returned no matches
• git diff --check

A broad go test run over those caller packages was stopped after two minutes without output. It is not recorded as a passing test; the normal full suite remains CI evidence for the branch.

Subsequent source moves

The following slices follow the same rule as the first three: each is a structural move with import rewrites, no compatibility shim, focused package and direct-caller validation, and git diff --check. They are recorded here while the branch is in flight; they do not describe the umbrella repository's main until its Spinifex gitlink is updated.

b1d0eba89	inline KV migration mechanics	spinifex/foundation/state/migrate	KV migration is a reusable state concern.
967f6904a	spinifex/kvlease	spinifex/foundation/state/kvlease	Leases are state foundation, not a resource-domain owner.
248f0e005, 8c4af3030	spinifex/formation	spinifex/runtime/formation	Formation owns its protocol payloads and remains runtime membership/bootstrap work.
b8b97279c, c0c64cd53	spinifex/instancecache	spinifex/runtime/compute/cache	Cache policy is decoupled from callers before becoming node-local compute runtime.
aa0c36ff4	spinifex/types/ec2.go	contracts/ec2/v1	The EC2 instance-command subject and JSON payload are an explicit versioned cross-process contract; commands_test.go is its compatibility evidence.
c239fd897	spinifex/types/eni.go	spinifex/runtime/compute/vm/eni_requests.go	PCIe hot-plug slot allocation is mutex-bearing, per-VM runtime state rather than a shared type or wire contract; record_test.go preserves its restart semantics.
6d6275e78	spinifex/types/cluster.go (NodeHealthResponse)	contracts/cluster/v1/health.go	Node health is a versioned cluster control-plane representation shared by the per-node NATS route and daemon HTTPS /health; health_test.go pins both wire forms.
53a614717	spinifex/types/cluster.go (SharedClusterData)	spinifex/daemon/config_hash.go	Shared-config hash input is daemon-local implementation data; focused config-hash tests preserve deterministic, shared-only semantics.
78fd017e0	spinifex/types/telemetry.go (GuestTelemetryMeta)	contracts/telemetry/v1/guest_meta.go	QMP collector sidecar JSON is a versioned file contract between VM runtime and telemetry role; guest_meta_test.go pins its filename and payload.
4b35a2a33	spinifex/types/node.go (NodeVMsResponse, VMInfo, VMGPUInfo)	contracts/cluster/v1/node_vms.go	VM inventory is a versioned cluster fan-out payload used by SPX CLI and EKS host lookup; node_vms_test.go pins its subject and JSON shape.
08bd335f0	spinifex/types/node.go (NodeStatusResponse, capacity and GPU inventory)	contracts/cluster/v1/status.go	Node status is a versioned fan-out observation contract for operator inspection and EC2/EKS scheduling consumers; status_test.go pins its subject and JSON shape.
f4cb550c9	spinifex/types/ebs.go (GP3 policy constants)	spinifex/domains/ec2/ebs/policy/gp3.go	The supported GP3 product envelope is EC2 EBS domain policy, not generic runtime or Viperblockd wire state; gp3_test.go pins the deployed values.
adb55de33	spinifex/types/ebs.go (NBDTransport)	spinifex/services/viperblockd/nbd_transport.go	NBD endpoint transport selection is Viperblockd-local delivery configuration, not generic EBS state or a provider contract; nbd_transport_test.go pins the socket and TCP forms.
94a6e7af2	spinifex/types/ebs.go (EBSConfigUpdateRequest, EBSConfigUpdateResponse)	contracts/viperblockd/legacy/v1/config_update.go	Legacy configuration updates have deployed queue and volume-addressed NATS routes; the versioned compatibility contract is expressly transitional and separate from providers/ebs.
b975f1ba9	Remaining spinifex/types/ebs.go payloads	runtime/compute/vm/ebs_requests.go and contracts/viperblockd/legacy/v1/volume.go	The mutex-bearing attachment collection is VM-owned; deployed mount, unmount and delete routes plus their JSON payloads are versioned Viperblockd legacy compatibility. Contract tests pin every route and JSON shape.
61cf833aa	spinifex/cloud/exoscale	spinifex/providers/cloud/exoscale	Exoscale CLI access is a replaceable external-cloud adapter. The source move rewrites its four Exonet callers and preserves its adapter tests and CLI boundary.
dbc62562c	spinifex/objectstore	spinifex/providers/objectstore	The generic S3-compatible client is a replaceable object-storage adapter, not S3 resource authority. The mechanical move rewrites all direct callers; its focused suite and caller compilation passed.
f11922986	spinifex/config	spinifex/bootstrap/config	Root configuration parsing belongs to bootstrap. Its package API is unchanged; package tests and regular, integration, E2E and benchmark caller compilation passed.
aa4b0b1bb	spinifex/paging	spinifex/foundation/aws/paging	Opaque listing tokens, deterministic slicing and EC2 pagination validation are shared AWS protocol infrastructure rather than EC2 resource authority. The move rewrites all five EC2 callers; focused package tests, direct caller compilation and tagged integration compilation passed.
6ac02a886	spinifex/clustersize	spinifex/foundation/state/clustersize	The declared cluster size and its fail-closed JetStream/KV replica policy are shared state-tier infrastructure, not a resource-domain owner. Focused package tests, all direct caller compilation, integration and E2E-tagged harness compilation passed.
93084043a	spinifex/handlers/ecr	spinifex/domains/ecr	ECR repository metadata, blob semantics and lifecycle rules are ECR domain ownership. The full domain suite, direct callers and tagged integration callers passed.
51b5c55b9	spinifex/gateway/ecrapi	spinifex/domains/ecr/awsapi	AWS JSON 1.1 action inventory, validation, resource-scope derivation and NATS-backed action handlers are ECR action-adapter ownership. Focused, gateway and tagged integration validation passed.
5e7311eb2	spinifex/gateway/ecr	spinifex/domains/ecr/registry	The OCI Distribution v2 protocol adapter is ECR data-plane ownership. Focused registry, gateway/AWS-gateway and tagged integration validation passed.
474c07316	spinifex/gateway/ecrauth	spinifex/domains/ecr/auth	ECR token claims, issuer/verifier, encrypted signing-key persistence and rotation are ECR credential ownership. Focused, gateway/AWS-gateway and tagged integration validation passed.
f59b40ad1	Gateway DescribeRepositories action semantics	spinifex/domains/ecr/awsapi.DescribeRepositories	Request validation, account scope, repository metadata lookup and AWS response projection are ECR AWS-action ownership. Gateway retains authenticated HTTP adaptation and response writing. Focused domain, gateway dispatch and tagged integration compilation passed.
c558872e8	Gateway CreateRepository action semantics	spinifex/domains/ecr/awsapi.CreateRepository	Request decoding, input defaults and validation, duplicate detection, account-scoped metadata persistence and AWS response projection are ECR AWS-action ownership. Gateway retains authenticated HTTP adaptation and response writing. Focused domain, gateway lifecycle and tagged integration validation passed.
a6b209b7b	Gateway DeleteRepository action semantics	spinifex/domains/ecr/awsapi.DeleteRepository	Request validation, account scope, non-empty protection, forced deletion, metadata cascade and AWS response projection are ECR AWS-action ownership. Blob reclamation remains the separately documented GC concern. Focused domain, gateway lifecycle and tagged integration validation passed.
7a5159366	Gateway PutImageTagMutability action	spinifex/domains/ecr/awsapi.PutImageTagMutability	This endpoint-free action is registered directly in the ECR action table rather than retained as a gateway wrapper. Request validation, account-scoped metadata update and AWS response construction are domain-adapter ownership; generic gateway auth and policy gating remain before dispatch. Focused domain, gateway and tagged integration validation passed.
a2f6005d2	Gateway GetAuthorizationToken action response	spinifex/domains/ecr/awsapi.GetAuthorizationToken	Gateway retains canonical IAM/STS principal construction from authenticated context. The ECR adapter consumes a narrow token-issuer capability and owns mint-result handling, Docker AWS:<jwt> encoding and AWS response projection. Focused domain, real issuer/verifier gateway round-trip and tagged integration validation passed.
ee4610a75	Gateway ListImages action semantics	spinifex/domains/ecr/awsapi.ListImages	The ECR AWS adapter consumes a narrow OCI image-catalog capability and owns request validation, account scope, tag-status projection and AWS response/error mapping. Gateway retains authenticated HTTP adaptation and supplies the configured registry. Focused domain, registry-backed gateway and tagged integration validation passed.
b22b723a4	Gateway DescribeImages action semantics	spinifex/domains/ecr/awsapi.DescribeImages	The ECR AWS adapter now shares the image-catalog capability and catalog error mapping with ListImages, and owns image selection/detail projection. The accepted-but-unapplied filter field is explicitly retained as an unchanged compatibility gap. Focused domain, registry-backed gateway and tagged integration validation passed.
deabaa300	Gateway BatchGetImage action semantics	spinifex/domains/ecr/awsapi.BatchGetImage	The ECR AWS adapter consumes a narrow manifest-reader capability and owns request validation, the 100-image cap, digest-over-tag selection and partial-failure response projection. Repository/account scope validation is now shared with ListImages and DescribeImages. Focused domain, registry-backed gateway and tagged integration validation passed.
2542ce98e	Gateway PutImage action semantics	spinifex/domains/ecr/awsapi.PutImage	The ECR AWS adapter consumes a narrow manifest-writer capability and owns request validation, tag/digest selection, AWS response projection and OCI manifest-store error translation. Gateway retains authenticated HTTP adaptation and supplies the configured registry. Focused domain, registry-backed gateway and tagged integration validation passed.
7666ed208	Gateway BatchDeleteImage action semantics and residual ECR helpers	spinifex/domains/ecr/awsapi.BatchDeleteImage, awsapi.ValidateRepositoryScope, gateway ecr_request.go	The ECR adapter consumes a narrow image-deleter capability and owns batch deletion/partial-failure projection. Completion exposed scope validation still needed by lifecycle-preview adapters, which now calls the exported ECR adapter utility; generic HTTP JSON decoding moved to a gateway ECR adapter helper. Focused domain, image/lifecycle gateway and tagged integration validation passed.
72c20bf78	Gateway lifecycle-preview evaluation and StartLifecyclePolicyPreview	spinifex/domains/ecr/awsapi.EvaluateLifecyclePreview, StartLifecyclePolicyPreview	Shared preview evaluation now consumes explicit policy-store and image-catalog capabilities, owns request/stored-policy resolution and lifecycle evaluation, and returns a reusable expiry set. Start preview is fully domain-owned; Get preview consumes the evaluator and retains only its response projection pending the next slice. Focused domain, lifecycle gateway and tagged integration validation passed.
68945bbb1	Gateway GetLifecyclePolicyPreview response projection	spinifex/domains/ecr/awsapi.GetLifecyclePolicyPreview	Get preview now joins Start preview in the ECR adapter, sharing the synchronous evaluator and explicit policy-store/image-catalog capabilities. Gateway retains only authenticated HTTP/body adaptation and capability supply. Focused domain, lifecycle gateway and tagged integration validation passed.
4c9f3d681	Gateway ECR image-action wrappers and residual JSON adapter	spinifex/domains/ecr/awsapi.RegistryActionService	ListImages, DescribeImages, BatchGetImage, PutImage and BatchDeleteImage now dispatch through one composed registry-action capability after the generic gateway's authentication and policy gate. The composition root supplies narrow OCI capabilities; the operation inventory derives their implemented status from that capability. The obsolete gateway wrappers and JSON helper are removed. Focused domain, gateway, AWS-gateway and tagged integration validation passed.
40e7b14ad	Gateway lifecycle-preview wrappers	spinifex/domains/ecr/awsapi.LifecyclePreviewActionService	StartLifecyclePolicyPreview and GetLifecyclePolicyPreview now dispatch through one composed policy-store-plus-image-catalog capability after generic authorization. Production reuses the registry's NATS metadata client; focused tests compose an in-memory metadata store. The obsolete wrappers are removed, and a missing composition fails closed rather than falling through to the raw action table. Focused domain, gateway, AWS-gateway and tagged integration validation passed.
54f96ad78	Gateway CreateRepository, DescribeRepositories and DeleteRepository wrappers	spinifex/domains/ecr/awsapi.RepositoryActionService	Repository actions now dispatch through one composed metadata-store-plus-endpoint-profile capability after generic authorization. The individual action adapters depend on a narrow repository metadata contract rather than constructing NATS clients themselves. The three obsolete wrappers are removed, and a missing composition fails closed. Focused domain, gateway, AWS-gateway and tagged integration validation passed.
5ebbdcb53	Gateway GetAuthorizationToken wrapper and endpoint adapter	spinifex/domains/ecr/awsapi.AuthorizationTokenActionService	GetAuthorizationToken now dispatches through a composed issuer-plus-endpoint capability after gateway constructs the canonical IAM/STS principal. The token subject remains gateway identity work; ECR retains credential response projection. The obsolete wrapper and endpoint adapter are removed, a missing action service fails closed, and an unavailable issuer retains the declared NotImplemented response. Focused domain, gateway, AWS-gateway and tagged integration validation passed.
2b945ad88	spinifex/handlers/acm, spinifex/gateway/acm	spinifex/domains/acm, spinifex/domains/acm/awsapi	ACM certificate state, issuance and renewal are ACM-domain ownership; its AWS JSON/NATS request adapters live beside them. All nine adapters, including the previously inlined RequestCertificate path, now use domains/acm/awsapi; generic gateway retains only routing, request context, policy gating and response writing. Focused domain, adapter and gateway request tests plus direct-caller and tagged integration compilation passed.
47c6b2fcf	spinifex/gateway/bodyscope	spinifex/ingress/aws/bodyscope	Case-aware, ambiguity-safe extraction of AWS JSON request identifiers is ingress policy machinery, not generic gateway ownership. Focused parser tests and compilation of all six direct service-policy consumers passed.
d3cd6d520	spinifex/gateway/policy	spinifex/foundation/aws/policy	AWS wire-service to IAM action-name mapping is protocol-neutral AWS vocabulary. Its focused suite and direct gateway/RDS/integration caller compilation passed.
be7f0b1d0	spinifex/utils/platform	spinifex/domains/ec2/platform	EC2 Platform and UsageOperation derivation is EC2 compatibility vocabulary, not a generic helper. Focused package and metadata-default tests, plus direct daemon/image/instance caller compilation, passed.
e2ac3dbed	spinifex/utils/command	spinifex/runtime/host/command	Bounded host-command execution is node-local runtime machinery. Focused command and host-DNS tests plus the direct SPX CLI caller compilation passed.
3360382f5	spinifex/utils/idempotency	spinifex/foundation/lifecycle/idempotency	Retry-token HTTP/NATS vocabulary now lives beside the idempotency store. Focused propagation and EIP retry behavior tests, affected package compilation and tagged integration compilation passed.
b5bc8cd7d	spinifex/utils/images (SelectNewestImage)	spinifex/foundation/aws/ami	Selecting the newest EC2 image from AWS SDK models is shared AWS-model logic used by EKS, ECS, RDS and Bedrock, not operator catalogue ownership. Focused selector and remaining catalogue tests plus all four direct caller compilations passed.
9f83f899a	spinifex/utils (ClientIP, RequestClientIP)	spinifex/ingress/http	HTTP remote-address parsing and loopback-trusted X-Real-IP handling are generic ingress policy shared by the AWS gateway and UI proxy. The moved test suite and all direct caller compilations passed.
693109950	spinifex/utils (HashMAC)	spinifex/network/identifiers	Deterministic locally-administered MAC derivation is network infrastructure shared by ENIs, DHCP, OVN topology, IMDS and VM tap setup. Focused MAC tests and every direct caller compilation passed.
79cf93996	spinifex/utils (DistinctIDs)	spinifex/foundation/aws/identifiers	Request-order-preserving normalization of AWS resource-ID lists is shared API-model handling used by image and snapshot enumeration. Focused tests and both direct caller compilations passed.
7e29f2640	spinifex/utils (download and terminal-progress helpers)	spinifex/operator/progress	Operator-facing downloads, terminal progress rendering and byte display are CLI presentation concerns. Focused tests and the spx admin compilation passed.
56471479f	spinifex/utils (ValidateKeyPairName)	spinifex/handlers/ec2/key	EC2 key-pair-name validation has one production owner and is now private to it. Its moved unit matrix and full key-handler suite passed.
cf531cd73	spinifex/utils (QMP telemetry filename convention)	contracts/telemetry/v1	The telemetry QMP prefix and metadata path are part of the existing VM-runtime-to-collector file contract. The contract test, focused VM telemetry tests, collector suite and caller compilations passed; the broader VM suite is sandbox-blocked by unrelated socket setup.
83615f1f4	spinifex/utils (AWS XML response helpers)	spinifex/foundation/aws/xml	EC2 XML response normalization/enveloping and IAM-style Query envelopes are shared AWS protocol mechanics. Focused XML tests and all direct caller compilations passed; the RDS-agent package was compile-checked without execution because its FIPS bootstrap requires a FIPS-enabled runtime.
9896834b2	spinifex/utils (ExtractTags, MapToEC2Tags)	spinifex/foundation/aws/tags	Generic EC2 tag-specification extraction and API-model projection join the AWS tag foundation; KV tag mirroring remains separate state-layer work. Focused tag tests and direct caller compilations passed; the volume package was compile-checked without execution because its test main opens a sandbox-blocked TCP listener.
d8985c287	spinifex/utils (AccountKey)	spinifex/foundation/state/kvutil	Account-scoped durable-key construction belongs to the state foundation; its {accountID}.{resourceID} layout is unchanged. AWS account policy (GlobalAccountID, IsAccountID) remains separate legacy utility work. Focused key and tag-mirror tests plus every direct resource-caller compilation passed.
e6794d87d	spinifex/utils (SudoCommand, NeedsPrivilege, EndpointSysctlHelper)	spinifex/runtime/host/command	Host-command privilege escalation is node-local runtime machinery and now sits beside bounded command execution. The RG-10 invariant restricting direct sudo construction to this package and network/host/run.go moves with it. Focused privilege, preflight, network-host, host-DNS and vpcd tests, every direct caller compilation and tagged integration/E2E compilation passed.
fd6c12f14	spinifex/utils (PID files, runtime directory, socket waits, process signalling and OOM score)	spinifex/runtime/host/process	Node-local process supervision shared by the daemon, VM runtime, Viperblockd and every named role is runtime host machinery. The remaining NBD endpoint helpers temporarily import it until they move to compute runtime. The shipped Viperblock unit comment still names utils.KillProcess; it is left unchanged so a structural move does not alter a delivered unit. Full preflight (excluding the pre-existing containerd advisory), focused caller suites and tagged integration/E2E compilation passed.
e712c6a7f	spinifex/utils (NBD socket paths, URI format/parse, readiness wait)	spinifex/runtime/compute/nbd	NBD endpoint naming and readiness join the node-local NBD runtime, removing the interim utils to runtime-host edge. The EBS provider conformance suite now imports compute runtime for the URI format; if a versioned EBS wire contract is introduced, that format is a candidate for contracts/ebs/v1. Full preflight (excluding the pre-existing containerd advisory), focused NBD, VM, Viperblockd, QEMU-NBD, EBS-provider and admin suites, and tagged integration/E2E compilation passed.

The EC2 contract row is intentionally different from the directory moves: it creates a compatibility boundary. ec2.cmd.* retains its deployed one-token NATS subscription and permission shape, while callers use InstanceCommandSubject rather than reconstructing the subject. The contract's README states the route, scope and change rule.

ECR composition boundary remaining

The ECR AWS JSON dispatcher and /v2/* route assembly remain methods on the generic GatewayConfig. They establish the generic HTTP route, authenticated request context, bounded-body read and policy gate, then invoke the ECR domain packages above. They are not moved merely to remove the last ECR-named files from gateway: doing so first would make the ECR domain own generic gateway state and policy mechanics.

Registry-backed image actions have now crossed this boundary through awsapi.RegistryActionService: the composition root supplies the OCI capabilities, and the generic gateway dispatches through it after authorization.

Lifecycle-preview actions have likewise crossed it through awsapi.LifecyclePreviewActionService, whose policy-store-plus-image-catalog dependencies remain explicit and separate from the registry image-action service.

Repository metadata actions have crossed it through awsapi.RepositoryActionService, which makes both their narrow metadata-store dependency and advertised endpoint profile composition explicit.

Authorization-token issuance has crossed it through awsapi.AuthorizationTokenActionService. Gateway intentionally still builds the canonical IAM/STS principal before dispatch, because ECR must not depend on gateway identity context or ARN construction.

All implemented ECR control-plane actions now dispatch through explicit ECR capabilities. The remaining ECR-named gateway code is generic /v2/* route assembly, SigV4/registry authentication and policy enforcement; it remains in gateway rather than inverting those dependencies into the ECR domain.

ACM relocation residuals

The ACM move leaves two pre-existing dependency seams visible rather than changing their behaviour in a structural slice:

• domains/acm.Store still imports IAM's AES-GCM helper functions. It does not read IAM records, but the crypto mechanism must move behind a shared crypto boundary before the final domain-dependency lint can prohibit that implementation import.
• GatewayConfig still owns the ACM action-name dispatch map. ACM owns the action adapters and resource-scope derivation, while generic gateway owns route handling, request context, policy gating and response writing. Moving service registration itself needs the later ingress registration contract; it is not hidden by a compatibility shim in this move.

Recording rule

For every later slice, add the old and new path, source commit, focused verification, and any finding exposed by the move. Record a conflict rather than folding a behavioural repair into a structural commit. When this branch is merged, the umbrella repository's execution plan records the resulting Spinifex commit.
