Status: NEW

Description

[Florian Zia [:flozia]]

Summary

The Smart Window mention data model is keyed by URL, but a tab group has no URL. ContextWebsite requires a url, MentionData.id is the URL, and deduplication is done on URL in multiple places. Referencing a tab group as context requires a mention type that is identified by group id instead.

Acceptance Criteria

• ContextWebsite supports type: "tabGroup" variant with groupId and color and can be identified with no url.
• MentionData.id accepts a group:<groupId> value for tab group mentions.
• Deduplication in SmartbarInputUtils.getMentionSuggestions(), SmartbarInput.getResolvedContextWebsites() and ai-window.#calculateCurrentMentions() has tab group entries keyed by groupId.
• removeContextMention() accepts a URL or groupId.
• Unit test coverage
