A composable pattern for pure state machines with effects

State machines are everywhere in interactive systems, but they're rarely defined clearly and explicitly. Given some big blob of code including implicit state machines, which transitions are possible and under what conditions? What effects take place on what transitions?

There are existing design patterns for state machines, but all the patterns I've seen complect side effects with the structure of the state machine itself. Instances of these patterns are difficult to test without mocking, and they end up with more dependencies. Worse, the classic patterns compose poorly: hierarchical state machines are typically not straightforward extensions. The functional programming world has solutions, but they don't transpose neatly enough to be broadly usable in mainstream languages.

Here I present a composable pattern for pure state machiness with effects,

Reason 1: Force Stopped

When an app is in a "Force Stopped" state most events including FCM/GCM messages for push notifications will not be received.

An app can be placed in this state in the following ways.

From Settings > Apps, "Force Stop" is pressed.
Long pressing the back button on some devices.
Using a 3rd party task killer like Greenify.
App is closed on a Huawei or Xiaomi device due their custom Android tweaks.
