AI Design Review: EP-306Score: 6/8 | Verdict: FAIL
Verdict: Architecturally excellent design with deep API field-level detail and clear boundaries, but the entirely placeholder Test Plan (zero on testability) triggers an automatic fail despite a 6/8 total. Feedback: The design's API Contract section and implementation detail are exemplary — field tables with type, presence, mutability, and validation for every resource set a high bar. To pass review, the Test Plan must describe concrete test scenarios at each level: unit tests (CIDR validation, overlap detection, SecurityGroupRule conflict rejection, attachment cardinality enforcement), integration tests (subnet creation with fabric+k8s managers on Kind cluster, ExternalIPAttachment precondition requeue, deletion dependency guard ordering), and e2e tests (full tenant workflow: create VN → Subnet → SecurityGroup → ComputeInstance/BaremetalInstance/Cluster → ExternalIP → ExternalIPAttachment → NATGateway → verify connectivity → cleanup). Graduation criteria should specify measurable conditions (e.g., 'all CRUD operations pass e2e for each resource type, auto-provisioning lifecycle works end-to-end, deletion dependency ordering enforced').

- Around line 1002-1003: The port-discovery example should use the tenant-facing
BareMetalInstanceType API as its sole source of truth. Update the paragraph’s
parenthetical links to remove HostType API, unless it is explicitly labeled as
provider or legacy context.
- Line 450: Clarify the cardinality semantics for
status.compute_network_attachment_statuses and
status.network_attachment_statuses: specify whether pending entries are emitted
before IP discovery or whether the resolved-attachment cardinality guarantee
applies only after discovery. Make both descriptions consistent and preserve the
stated single-attachment mapping behavior.
- Line 1290: Update the cleanup contract near the finalizer-removal behavior to
identify the controlling retry-limit configuration and its default value, then
document the owner responsible for orphan cleanup and the operator procedure for
identifying resources via auto-created-for and repairing or removing them.
- Around line 260-282: Define the Create-time normalization flow for legacy-only
spec.ingress and spec.egress: convert representable legacy rules into the
canonical spec.rules representation before validating the required nonempty
invariant, then persist the normalized canonical rules while retaining legacy
fields only for compatibility reads as appropriate. Alternatively, explicitly
make the legacy fields read-only and remove wording that permits legacy input;
do not state that legacy-only requests are necessarily rejected.

| #### Methods | ||
|
|

| | Method | Caller | Contract | | ||
| |---|---|---| | ||
| | `List` | Tenant or provider | Lists SecurityGroups visible in the caller's tenant/project or provider scope. | | ||

| | `Create` | Tenant or provider | Validates the parent VirtualNetwork and canonical or legacy rules before persistence. | | ||
| | `Delete` | Tenant or provider | Deletes the group only when no workload attachment references it; the system fallback group is provider-managed. | | ||
| | `Update` | Not supported | Parent, rules, metadata, and effective policy are immutable; replacement requires delete and create. | | ||
| | Private reconciliation | Networking controller | Updates only state, diagnostics, hub placement, and finalizers. | | ||

|
||
| | Field | Meaning | Type | Presence and mutability | Validation | | ||
| |---|---|---|---|---| | ||
| | `spec.virtual_network` | VirtualNetwork whose workloads may use the group | `VirtualNetworkLocalReference` | Required; immutable | Parent must be `READY` and in the same scope. | | ||
| | `spec.ingress` | Legacy inbound rule list | List of `SecurityRule` | Legacy input/read compatibility; immutable after create | Cannot be combined with canonical `rules`; only representable IPv4 rules are accepted. | | ||
| | `spec.egress` | Legacy outbound rule list | List of `SecurityRule` | Legacy input/read compatibility; immutable after create | Same compatibility rules as `ingress`. | | ||
| | `spec.rules` | Canonical tenant firewall rules | List of `SecurityGroupRule` | Required for tenant-created groups; immutable | A tenant-created group has at least one rule. The system-created fallback group may be empty. Duplicates and conflicting equal-specificity rules are rejected. | |

Define how legacy rules satisfy the canonical rule invariant.
The contract calls spec.ingress and spec.egress legacy input fields, and Create accepts canonical or legacy rules. However, tenant-created groups also require a nonempty spec.rules list, and the design does not state how legacy-only input becomes canonical rules before that check. Define this normalization and persistence behavior, or mark these fields as read-only and remove the input-compatibility wording. Do not describe legacy-only requests as necessarily rejected.

Resolve the attachment-status cardinality contradiction.
status.compute_network_attachment_statuses is described as empty until IP discovery and also as having cardinality equal to the resolved attachment. With one resolved attachment and no discovered IP, these rules conflict. The same conflict exists in status.network_attachment_statuses on Line 519. State whether pending entries are emitted or whether cardinality applies only after discovery.

Use the tenant-facing port catalog in this example.
This paragraph says that tenants discover ports from BareMetalInstanceType, but the parenthetical also links HostType API. The HostType section says that HostType is not the source of truth for workload networking. Link only BareMetalInstanceType API, or label HostType API as provider or legacy context.

Define the retry and orphan-cleanup contract.
The document states that the finalizer is removed after a configured retry limit and that orphaned resources remain identifiable by auto-created-for. It does not state the configuration source or default, or define who performs manual cleanup and how operators repair the orphaned resources. Reference the controlling configuration and document the cleanup owner and procedure.
