A corollary is a proposition that follows directly from a theorem or principal result already established, requiring little or no additional proof to establish its truth. Its parameters are: (1) it must derive from a prior proved statement; (2) its proof is immediate or trivial relative to the parent theorem; (3) it is named and separated so it can be cited independently. It persists as a conventional unit of mathematical communication — a packaging device that lets later work cite a derived fact without reproducing its (often simple) derivation.

Definition
Why it is in scope
corollary is a human-made epistemic concept in mathematics and formal discourse — a proposition that follows directly from a proved theorem, requiring little additional argument. It is a device for packaging deductive consequences as standalone claims.

corollary cannot exist without a prior proved theorem — the theorem is the parent from which the corollary is derived. The theorem existed first and fed into the corollary.

A corollary IS a specific kind of proposition — one that follows readily from a proposition already proven or established. Direction: specific→general. Precheck clear: no corollary↔proposition edge exists.

Law 8b removal test: the board's corollary is carved as 'a proposition that follows directly from a theorem or principal result already established, requiring little or no additional proof.' The theorem is the constitutive object of the corollary's mechanism — the prior proved statement it immediately follows. Remove the theorem (the category of established results) and the corollary has nothing to follow from: the proposition degrades into a bare proposition, its 'immediate derivation' mechanism ceases to operate. Same shape as the accepted screwdriver->screw and limiting->threshold: the operating object, not a purpose (SERVES would require the corollary to be built for the theorem's sake — it is not; it is built for the sake of the result's economy of proof) and not identity (a corollary is not a theorem — Law 8c). Distinct from the accepted corollary DERIVED_FROM theorem, which records Law 7's which-came-first (theorem as concept predates corollary as term of art): this edge records that the corollary's OPERATION requires the theorem as its object.
