Source types used
- manufacturer, retailer, support or policy pages where they clarify product identity, specifications, ownership terms or route fit
- UK Shortlists shortlist metadata, review-basis fields, evidence summaries, methodology notes and change logs already present in the repository
- stable expert or editorial sources only as corroborating context where they help explain trade-offs or caveats
- merchant-context checks for current checkout caveats, without treating the page as a live price, stock or availability feed
