# Official sources

Use this reference only when you need source grounding for Alibaba Cloud governance service behavior or the detailed source list.

## Alibaba Cloud documentation

Use these as starting points, not as proof of the user's live Alibaba Cloud state:

## Grounding rule

Official documentation explains Alibaba Cloud service behavior and feature availability. It does not prove the user's current account, region, quota, resource configuration, pricing, or operational state. Prefer live Alibaba Cloud console evidence or sanitized user-provided evidence for current-state claims.
