A local-first client for a conversational agent with a real-time 2D avatar.

The application is a static HTML/JavaScript runtime. Thin native hosts load the same tree on Windows (Electron) and Android (WebView). Language and speech models are attached at run time through operator-configured HTTP APIs (OpenAI-compatible chat completions, plus optional TTS backends).

面向实时二维立绘的本地对话客户端。应用核为静态 HTML/JavaScript；Windows（Electron）与 Android（WebView）仅提供宿主。语言模型与语音合成在运行时接入操作者配置的 HTTP API。

Version is pinned in config/version.json (single source of truth for the exe and the APK); releases are at GitHub Releases. License: MIT.

The three hosts share one proxy contract, GET/POST /_proxy, so browser and WebView code can call operator endpoints without a CORS failure. The development server is python scripts/serve.py (http://127.0.0.1:8765/). A plain http.server is insufficient because it does not implement the proxy.

三端共用 /_proxy。开发请用 scripts/serve.py，不要用 python -m http.server。

Inference is not bundled. Settings require an OpenAI-compatible base URL, model identifier, and API key; TTS is optional and uses per-provider credential fields (openai / qwen / fish). NSFW/undress is disabled by default and can only be enabled explicitly in Settings; the AI cannot enable it while permission is off.

推理与语音不随仓库分发，由设置页配置。

• Dialogue modes: chat, story, immersive, ASMR, text
• Spine 4.2 portrait and scene graph (posture, camera, tap hit-testing)
• Local RPG-style state: stamina, quests, inventory, daily rewards (localStorage)
• Two-layer session memory, independent of adventure logs
• Four language slots (UI, bundled voice, LLM output, TTS), seven UI locales
• Tagged replies for scene side effects; numeric deltas in a trailing <state> block (no function-calling requirement)

Structural tables (JSON, atlas, SVG) live in web/assets/ and are versioned with the client. Large binaries (raster, audio, skeleton) are excluded from version control and restored before a full session or packaged build:

结构表随仓库版本管理；体积较大的栅格图、音频与骨骼二进制在完整运行或打包前本地恢复：

python scripts/restore_media.py path\to\RyzaChat-1.2.22.apk
python scripts/restore_media.py path\to\win-unpacked\resources\web

If asset files change, regenerate indexes with python scripts/build_indexes.py.

Copy config/providers.example.json to config/providers.json for local hydration. That file is gitignored. Packaged hosts do not embed it; keys remain in the app profile (localStorage or %AppData%\RyzaChat). scripts/privacy_check.py is a packaging gate: a non-zero exit aborts desktop and APK builds when a secret-shaped token or machine-local path would be included.

python scripts/serve.py                          # browser
cd desktop; npm install; npx electron .          # desktop
powershell -File scripts/build_desktop.ps1       # NSIS installer
powershell -File scripts/setup_android_tools.ps1 # JDK 17 + SDK (once)
powershell -File scripts/build_apk.ps1           # APK

Android toolchain path: environment RYZA_ANDROID_TOOLS, or gitignored config/android-tools.local.txt.
