Summary

Product types gain savedToLineItem on attribute definitions (released 2026-09-30): whether the attribute value is copied onto Line Items.

 attributeDefinitionFromAttributeDefinitionDraft(draft)
   isSearchable: draft.isSearchable ?? true
+  savedToLineItem: draft.savedToLineItem ?? true

 ProductTypeUpdateHandler
   setKey
+  setSavedToLineItem(attributeName, savedToLineItem)

• AttributeDefinitionDraftSchema accepts savedToLineItem. The RAML spec has it, the OpenAPI spec (oas/api/openapi.yaml, api-reference f6f6f57) does not yet, so EXTRA_PROPERTIES in generate-schemas.ts patches it in. The schema line is what the generator emits with that patch; the rest of a full regeneration was left out.
• Typed locally: @commercetools/platform-sdk 9.7.0 has the type, but bumping to it also makes Category.stores required, which is its own change.

Needed by the saved_to_line_item support in terraform-provider-commercetools (labd/terraform-provider-commercetools#679), whose acceptance tests run against this mock.

Evidence

• Before: the draft field is stripped by the schema, the attribute reads back without it, and setSavedToLineItem is not handled.
  After: new test Update product type - setSavedToLineItem: create [false, unset] → reads [false, true]; update → [true, false]. Create product type now expects savedToLineItem: true.
• pnpm check clean (the one biome warning is on main too); pnpm test: 87 files, 947 tests pass.
• terraform-provider-commercetools TestAccProductTypes_* with saved_to_line_item pass against this branch.

Merge Danger

Door: two-way

Blast Radius: small

Product type attributes in mock responses gain savedToLineItem: true by default, matching the API. Consumers that toEqual whole attribute definitions in their own tests will need the field.
