# Official sources

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

## Alibaba Cloud documentation

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

## Grounding rule

Official documentation explains Alibaba Cloud service behavior. It does not prove the user's current account, Region, quota, resource configuration, RAM policy boundary, pricing, or operational state. Prefer live evidence or sanitized user-provided evidence for current-state claims.
