packages/sdk/src/model-meta-generator.ts (3)

83-88: LGTM! Proper use of type-only import.

The type-only import of ModelMeta is appropriate since it's used solely for type annotation on line 96, which helps prevent unnecessary runtime dependencies.

---

96-96: LGTM! Type annotation improves type safety.

Adding the explicit ModelMeta type annotation ensures the generated metadata object conforms to the runtime type definition at compile time, catching any structural mismatches early.

---

371-383: Confirm undefined fallback for unrecognized expressions
exprToValue ends with .otherwise(() => undefined), so value can legitimately be undefined. Verify this fallback is intentional and that downstream consumers handle missing argument values appropriately.

packages/runtime/src/cross/model-meta.ts (1)

15-15: No action needed—optional value is safely handled in runtime consumers.
In packages/runtime/src/cross/mutator.ts, code checks defaultAttr?.args[0]?.value !== undefined before accessing defaultAttr.args[0].value, so making RuntimeAttribute.args[].value optional won’t introduce runtime errors.
