- app/, components/, lib/, i18n/, tests/, proxy renamed via git mv - types carried into JSDoc: @template generics, @typedef aliases, /** @type */ casts where TS had as-casts or non-null assertions - role tuple keeps its const assertion; the db-enum drift guard now checks the tuple values against the generated enum type - use client/use server directives and server-only imports preserved - prettier-formatted; vitest suite unchanged
