+/// NOTE: This test intentionally uses `-convert-to-emitc` only.
+///
+/// The `-convert-memref-to-emitc` pass introduces
+/// `builtin.unrealized_conversion_cast` operations when lowering
+/// `memref.alloc` results (which are lowered to `emitc.ptr`) to the canonical
+/// memref representation used by the type converter (`emitc.array`).
+/// These casts are expected at that stage of the pipeline.
+///
+/// The purpose of this test is to verify the final lowering produced by
+/// `-convert-to-emitc`, where `memref.load` and `memref.store` conversions now
+/// handle pointer-backed buffers directly and eliminate the intermediate
+/// `unrealized_conversion_cast`.
+/// Therefore, the test must run the full EmitC conversion pipeline.

I believe the summary is already covered (?)
