		# @contractkit/contractkit-plugin-typescript

		## 0.17.0

		### Minor Changes

		- b3f7da9: Fix `ref & ref` type alias intersections generating `ZodIntersection` instead of `ZodObject`

		Contracts like `contract Foo: A & B` (two model refs, no inline fields) previously emitted `A.and(B)`, producing a `ZodIntersection`. This broke `.strict()` calls on the result and caused each strict schema to reject the other's keys at runtime.

		All three rendering paths (`renderIntersection`, `renderInputType`, `renderQueryType`) now emit `.extend(B.shape)` chains for any `ref & (ref \| inlineObject)*` intersection, matching the pattern already used for multi-base model inheritance.
