Explanation of absolute_floor_iff_bare_distinguishability

(1) Plain English

The theorem asserts that, for any nonempty carrier type K, the structure AbsoluteFloorWitness K (which packages meta-language proposition distinguishability together with a nontrivial specification) is logically equivalent to the bare existence of two distinct elements x, y : K with x ≠ y.

(2) Why it matters in Recognition Science

This equivalence closes the absolute-floor program. It reduces the foundational precondition of the entire RS forcing chain to meta-language proposition distinguishability plus a non-singleton universe of discourse, rather than an RS-specific physical postulate. See floor_status.

(3) How to read the formal statement

theorem absolute_floor_iff_bare_distinguishability
    {K : Type*} [Nonempty K] :
    AbsoluteFloorWitness K ↔ ∃ x y : K, x ≠ y :=
  ⟨bare_distinguishability_of_absolute_floor, absolute_floor_of_bare_distinguishability⟩

The left-to-right direction extracts bare distinguishability from the witness; the right-to-left direction constructs the witness from bare distinguishability (using the imported distinguishability_iff_nontrivial_specifiability and the meta-language fact meta_language_distinguishes_props).

(4) Visible dependencies or certificates

(5) What this declaration does not prove

It establishes only the equivalence on an inhabited carrier. It does not prove the existence of any particular nonempty K, the full forcing chain to spacetime or constants, or any physical predictions.
