- Composing TLA+ specifications using state machines to allow independent development and minimal overhead integration.
- Using primed variables in TLA+ to constrain and assign next-state values, enabling synchronization between components.
- Defining a system spec with Sync action to add guards and side-effects for composing worker and server specifications.
- Ensuring composition correctness via refinement properties, guaranteeing liveness and avoiding deadlocks.
- Comparing the Sync-based approach with conventional composition, highlighting maintainability and scalability advantages.
