would anyone be able to assist me in figuring out what my

expect

declaration should look like in order to be able to use the following (delegating to Gson) type annotation on my (cross-platform/shared) data models:

actual typealias SerializedName = com.google.gson.annotations.SerializedName

this:

expect annotation class SerializedName(val value: String, val alternate: Array<String> = [])

results in error:

Parameter 'alternate' has conflicting values in the expected and actual annotation

Sounds like you're running into https://youtrack.jetbrains.com/issue/KT-22704

Ah, that does indeed seem to be the case! Thank you! Well, at least it appears I can get around it for now by annotating my classes with

@SerializedName("value", [])

. Ugly, but works.
