Quiddity
v0.1.0
Rules Engine

Quiddity.core

A headless SRD 5.2 rules engine written in Rust and compiled to WebAssembly. Resolves tabletop RPG mechanics — ability checks, attacks, damage, healing, HP tracking — without any UI. Immutable state model: every action returns a new game state, event log, and optional prompt.

Demos 02

These demos are intentionally minimal and self-contained. They exist to show how Quiddity integrates into different game formats — not to be polished products. Rendering, narrative, and content are kept deliberately light so the engine mechanics stay in focus.
