This is a full-stack cultivation world simulator game (xianxia RPG) with a Python backend (FastAPI + asyncio) and a Vue 3 + TypeScript + PixiJS frontend, supported by an optional Electron desktop shell for Epic Games Store distribution. The simulation engine runs a month-by-month tick system orchestrating ~29 phases (lifecycle, actions, social, war, world events, etc.) producing emergent narratives driven by LLM calls (OpenAI/Anthropic compatible) for character decisions, story generation, world lore rewriting, and roleplay interactions. The codebase is heavily data-driven with static game configurations (sects, techniques, items, regions) loaded from CSV files and multi-language localization via gettext PO files. It exposes a public REST API (query/command) and WebSocket for real-time state updates, supports save/load with JSON snapshots and SQLite event storage, and includes comprehensive test coverage (pytest, vitest, Playwright) and CI/CD workflows. While the architecture shows strong engineering patterns (effect system, action registry, single-choice decision framework, phased simulation pipeline), it carries risks from tight coupling of global singleton registries, LLM dependency, and use of `eval` in effect conditions.
