vpc_subnet.go:68

• GetCreateOptions was not updated for this newly writable field, so converting a returned subnet back to create options silently drops its NAT gateway ID. Populate the option from the response model and extend the conversion assertion to cover it.

	NATGateway *VPCSubnetCreateOptionsNATGateway `json:"natgateway,omitzero"`

nat_gateways.go:49

• Repository guidance requires optional create/update fields to use omitzero (AGENTS.md:40). Keep this new options type consistent; for a pointer this retains the same omission behavior while using the required tag.

	Label *string `json:"label,omitempty"`

nat_gateways.go:122

• This exported update signature reverses the established ID-before-options order used by UpdateVPCSubnet, UpdateVolume, and other ID-scoped updates. Define it as (ctx, id, opts) now; correcting the ordering after release would require a breaking API change.

func (c *Client) UpdateNATGateway(ctx context.Context, opts NATGatewayUpdateOptions, id int) (*NATGateway, error) {

nat_gateways.go:134

• The subordinate public methods switch from the file's verb-first naming (ListNATGateways, GetNATGateway) to NATGateway<Action>, and place options before the gateway ID. Rename this family consistently—for example, AddNATGatewayAddress(ctx, id, opts), ListNATGatewayAddresses(ctx, id, opts), and GetNATGatewaySettings—before the API is released.

func (c *Client) NATGatewayAddAddress(ctx context.Context, opts NATGatewayAddAddressOptions, id int) (*NATGatewayAddressObject, error) {

nat_gateways.go:133

• Correct the typo in the exported method documentation.

// NATGatewayAddAddress adds an addresd to the NAT Gateway with the specified id
