Dagger assisted injection: Type projection broken since Anvil 2.4.3

[consp1racy]

Given

class CachingSerialNumbers @AssistedInject constructor(
    private val store: DataStore<SerialNumber?>,
    @Assisted actual: @JvmSuppressWildcards Provider<out SerialNumbers>,
) : SerialNumbers {

    @AssistedFactory
    interface Factory {

        fun create(actual: @JvmSuppressWildcards Provider<out SerialNumbers>): CachingSerialNumbers
    }

    // ...
}

Anvil 2.4.2 generates working

public class CachingSerialNumbers_Factory(
  private val store: Provider<@JvmSuppressWildcards DataStore<SerialNumber?>>,
) {
  public fun `get`(`actual`: @JvmSuppressWildcards Provider<out SerialNumbers>):
      CachingSerialNumbers = newInstance(store.get(), actual)

  public companion object {
    @JvmStatic
    public fun create(store: Provider<@JvmSuppressWildcards DataStore<SerialNumber?>>):
        CachingSerialNumbers_Factory = CachingSerialNumbers_Factory(store)

    @JvmStatic
    public fun newInstance(store: @JvmSuppressWildcards DataStore<SerialNumber?>,
        `actual`: @JvmSuppressWildcards Provider<out SerialNumbers>): CachingSerialNumbers =
        CachingSerialNumbers(store, actual)
  }
}

and Anvil 2.4.3 generates

public class CachingSerialNumbers_Factory(
  private val store: Provider<@JvmSuppressWildcards DataStore<SerialNumber?>>,
) {
  public fun `get`(`actual`: Provider<@JvmSuppressWildcards SerialNumbers>): CachingSerialNumbers =
      newInstance(store.get(), actual)

  public companion object {
    @JvmStatic
    public fun create(store: Provider<@JvmSuppressWildcards DataStore<SerialNumber?>>):
        CachingSerialNumbers_Factory = CachingSerialNumbers_Factory(store)

    @JvmStatic
    public fun newInstance(store: @JvmSuppressWildcards DataStore<SerialNumber?>,
        `actual`: Provider<@JvmSuppressWildcards SerialNumbers>): CachingSerialNumbers =
        CachingSerialNumbers(store, actual)
  }
}

which fails with

> Task [...]:compileKotlin FAILED
e: [...]\build\anvil\src-gen-main\[...]\CachingSerialNumbers_Factory_Impl.kt: (23, 27): Type mismatch: inferred ty
pe is Provider<out SerialNumbers> but Provider<SerialNumbers> was expected

Because Anvil generates Kotlin source from Kotlin source, the annotations and projections need to be copied verbatim.

Dirty workaround

class CachingSerialNumbers @AssistedInject constructor(
    private val store: DataStore<SerialNumber?>,
    @Assisted actual: Provider<SerialNumbers>,
) : SerialNumbers {

    @AssistedFactory
    interface Factory {

        fun createImpl(actual: Provider<SerialNumbers>): CachingSerialNumbers

        @Suppress("UNCHECKED_CAST")
        fun create(actual: @JvmSuppressWildcards Provider<out SerialNumbers>): CachingSerialNumbers {
            return createImpl(actual as Provider<SerialNumbers>)
        }
    }

    // ...
}
