Thanks for organising, I’d be happy to present:

**Title** : Towards simulation testing in Rust  
**Description** : I’ll summarise Roland’s new stage graph API and show how it can be used to write a deterministic simulator.  
**Duration** : 10 min including discussion

This is related to the action item “Refactor Amaru consensus to ease implementing deterministic testing” and the sessions:

- [Back pressured, deterministic processing networks](https://forum.cardano.org/t/node-diversity-workshop-april-2025/145248#p-370332-back-pressured-deterministic-processing-networks-9)
- [Coroutines/Generators vs. explicit state machines](https://forum.cardano.org/t/node-diversity-workshop-april-2025/145248#p-370332-coroutinesgenerators-vs-explicit-state-machines-20)
- Property-based testing state machine testing
- Rust software design session
