Explanation of every_distinguished_carrier_maps_uniquely_to_reality
(1) In plain English: For any "distinguished carrier" (a type equipped with two named, distinct points), there exists exactly one morphism to the terminal reality object. This morphism is the proof that a RealityCertificate exists for the carrier's underlying type. All carriers therefore share the same unique reality content in the propositional sense.
(2) Why it matters in Recognition Science: The theorem packages the master theorem categorically as a terminal object. It shows that reality is forced uniformly from any single distinction, giving a universal, proof-irrelevant certificate that every admissible carrier maps into uniquely. This supplies the terminality property required for the framework's claim that distinction alone determines reality.
(3) How to read the formal statement: The declaration
theorem every_distinguished_carrier_maps_uniquely_to_reality
(A : DistinguishedCarrier) :
∃! f : TerminalArrow A, True :=
terminalArrow_unique_exists A
states that for any A : DistinguishedCarrier, there is a unique f of type TerminalArrow A (itself defined as RealityCertificate A.Carrier) satisfying True. The ∃! quantifier encodes existence plus uniqueness. The proof simply invokes the packaged helper terminalArrow_unique_exists.
(4) Visible dependencies or certificates in the supplied source: The theorem is proved directly by terminalArrow_unique_exists, which is defined in the same module using terminalArrow_exists and terminalArrow_unique. The module also defines the concrete terminal object terminalReality on boolObject and packages the universal property inside the certificate structure realityTerminalCert.
(5) What this declaration does not prove: It does not establish the definition or properties of RealityCertificate, nor the underlying lemma reality_from_one_distinction. It assumes proof irrelevance for uniqueness and supplies no link to the forcing-chain theorems, cost functional equation, dimension forcing, or mass derivations present in other supplied modules.
