# Viat product handbook

> Server/CLI baseline 1.1.0; native client 0.1.0 is independently versioned.
> Documentation reconstruction preview; final acceptance is incomplete. Read explicit limitations and do not invent missing commands or integrations.

## Documentation
- [简体中文](https://docs.viat.dev/llms-zh-cn.txt): Chinese task and reference index.
- [English](https://docs.viat.dev/llms-en.txt): English task and reference index.
- [Contract provenance](https://docs.viat.dev/contracts/manifest.json): Source revision, artifact version and candidate/review state.

## Operating rules
- Confirm instance, project, identity and installed version before acting.
- Do not invent commands, silently accept publication warnings or equate tool success with business success.
- Real messages, paid model calls and device operations require explicit opt-in.
- Preview capabilities are not stable release capabilities. Raw Markdown is available per page.
