Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to This change adds SpectrumX attachments to instance create, batch-create, and update operations. At the current head, an update that omits the attachment field can clear existing attachments, while some accepted attachment types may fail or change meaning downstream and oversized IDs may convert incorrectly. These are concrete correctness and availability risks, so the PR is not merge-ready until they are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

There was a problem hiding this comment.
The field comment and the OpenAPI description both say virtualFunctionId "must be specified if attachmentType is Virtual", but the validator only enforces the other direction (set on non-Virtual is rejected), and the test "Virtual attachment without virtualFunctionId" pins the permissive behavior as success. The InfiniBand analog requires the VF when isPhysical is false, per its own spec text. Which is the contract? If the Site assigns a VF when it is omitted, the comment and spec should say "optional, assigned by the Site when omitted"; if not, the validator needs the missing direction. Right now a client following the docs and a client following the behavior disagree.

Attachments are validated one at a time, so two entries with the same device, deviceInstance, and virtualFunctionId (or the same partition attached twice to one slot) pass validation and travel to the Site. The list is also unbounded, while Interfaces caps at MaxInterfaceCount. We should reject duplicate device/instance/VF tuples across the list and put a cap on it, matching how the other per-Instance lists are treated?

[P2] Mark SpectrumX attachment updates as configuring
SpectrumXAttachments is included in IsUpdateRequest, but it is omitted from IsInterfaceUpdateRequest immediately below. The handler only sets InstanceStatusConfiguring when IsInterfaceUpdateRequest is true, while the UpdateInstance workflow returns as soon as Core accepts the desired config; DPA convergence happens later. A SpectrumX-only PATCH therefore returns the prior status, typically Ready, while the attachment change is still pending. Include iur.SpectrumXAttachments != nil in IsInterfaceUpdateRequest and cover the returned status in the handler test.

East-West networking changes don't switch Instance status immediately, Core will decide.

[P2] Reject an omitted deviceInstance instead of selecting device 0
deviceInstance is required by the OpenAPI schema, but this DTO stores it as an int. When direct HTTP JSON omits the property, decoding leaves the zero value and the Min(0) rule accepts it; ToProto then silently targets device instance 0. Use a presence-aware representation such as *int with a required check so explicit zero remains valid but omission is rejected, and add a JSON-boundary regression case.
