Is there a way to always trigger recomposition by setting a MutableState variable, including when the contents are the same? I've Tried creating my own SnapshotMutationPolicy but the merge method never gets called.

Override the equals() function and return false I guess

This is a code smell. What are you really trying to do?

I've done that already @André Kindwall.
Here is a full implementation of my SnapshotMutationPolicy

private object AlwaysApplyPolicy : SnapshotMutationPolicy<String> {

    override fun equivalent(a: String, b: String): Boolean = false

    override fun merge(previous: String, current: String, applied: String): String? {
        return current
    }

    override fun toString() = "AlwaysApplyPolicy"
}

What I want is for the State backed by this snapshot policy to always force a recomposition when it's value get's set, even if the previous value is equal to the current value.

You should probably ask a new question where you describe what you want to achieve, not how you think you can achieve it (the xy problem).

It sounds to me like you are trying to trigger some event, if that is the case then that should be handled by collecting a flow inside a sideeffect

Why do you want to recompose with the same value?
