Debug turn-based game loop execution order in Rust by mapping the sequencing of update, end_turn, and event processing systems to ensure deterministic state transitions. This Skill documents the main loop, action dispatch, and system call order to help reason about per-turn logic.

The correct system call order for turn processing in a deterministic game loop follows a strict sequence of input handling, update, end_turn, and event processing. Modeling these dependencies and sequencing ensures deterministic understanding of state updates and action routing.

Add new per-turn features to a turn-based engine without breaking execution order by following the documented action dispatch mapping for systems like Move, EndTurn, and Wait. The Skill provides extension guidance to route new actions through the correct update and event processing phases.

This game loop documentation is specifically designed for deterministic turn-based engines, focusing on per-turn orchestration and discrete action dispatch. It is not intended for real-time event processing or continuous game loops outside a turn-based context.

Turn-based logic produces non-deterministic results during event processing when system dependencies and sequencing in the update loop or end_turn order are not strictly modeled. This Skill maps the exact execution order across update and event phases to resolve such state transition conflicts.
