fixed-point

Deterministic ECS simulation core for C# games, built for Godot. Same seed and inputs give the same world, bit for bit: fixed-point maths, seeded RNG, fixed ordering, and analyzers that turn non-deterministic code into build errors. Per-tick change sets and state hashing make saves, replays and multiplayer possible. Engine-agnostic core plus a Godot transport layer.
