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.
