# G18 Hreflang and locale alternative graph

## Question

Which localized documents are alternatives for the same user task?

## Nodes

Localized page; Language; Region; Alternate group

## Relationship sketch

* page → locale
* page → alternate page

## Evidence inputs

Actual translated/localized pages and annotations, canonical policy, language/region intent.

## Implementation

Validate reciprocal alternative sets under the current implementation method. Do not confuse localization with location claims or populate a graph using untranslated duplicate pages.

## Acceptance checks

* Alternate URLs resolve as intended
* Annotation sets are consistent and reciprocal where required
* Language/region intent matches actual content

## Do not infer

An alternate language page is not a different business entity.

## Publication boundary

Appropriate locale annotations public.
