The scanner, the food guide, and the method all belong to one halal food surface. These are the questions people ask first.
No. The scanner is designed to show different evidence states clearly. A product may resolve to a catalog match with no certifier record yet, or it may only have company-level context. Unknown remains unknown when the evidence is not strong enough.
Because product identity is the anchor for everything else. If the underlying product match is weak, then the halal statement built on top of it will also be weak.
No. The scanner is one feature inside a broader halal food surface that includes ingredient explainers, method notes, topic pages, and public educational material.
Not necessarily. Company context is useful, but it is weaker than a direct product certification. Tayyib keeps those states separate on purpose.
