## How to read this

- Each category is researched in four independent runs, one per lens (expert consensus, value, reliability, community pulse). Every run ranks a board of candidates that deliberately includes products buyers cross-shop but should avoid. Placements score on a ranked ladder (LP), and tiers are derived from LP, so no tier is ever assigned by hand.
- LP is the product's points on this category's ladder. It is comparable within a category and not across categories.
- Outlets is how many distinct outlets are cited for that placement. The per-product page lists each citation, and shows which of their links were fetched and confirmed before publishing.
- Nothing is hidden: every product the research placed is on this board.
