-- Community OEM cross-reference suggestions, collected on the OEM detail page
-- ("muadil parça öner": brand + code). Primarily for codes the P snapshot has
-- no match for. suggested_code_norm (upper alphanumerics) powers grouping and
-- the per-user dedup; status is a moderation hook (active|hidden).
