Explain the Lean theorem `match_boson_Z` in module `IndisputableMonolith.Masses.RungConstructor.Proofs`. Write for an educated reader who knows science and programming but may not know Lean. Cover: (1) what the declaration says in plain English, (2) why it matters in Recognition Science, (3) how to read the formal statement, (4) visible dependencies or certificates in the supplied source, and (5) what this declaration does not prove. Cite only declarations present in the supplied Recognition source.

Explanation of match_boson_Z

(1) In plain English, the declaration asserts that the rung constructor assigns the integer value 1 to the Z boson.

(2) In Recognition Science this matters because rungs on the recognition ladder set the exponent in the mass scaling formula (yardstick times a power of φ). Confirming that W, Z and H all sit at rung 1 reproduces the boson sector of the observed particle table inside the parameter-free constructor.

(3) The formal statement is theorem match_boson_Z : compute_rung .Z = 1 := by rfl. In ordinary mathematical notation this is simply compute_rung(Z) = 1. The proof tactic rfl means the equality holds definitionally from the constructor’s definition (no further reasoning required).

(4) Visible dependencies in the supplied source: the theorem is proved by reflexivity and appears alongside the parallel statements match_boson_W and match_boson_H. The SDGT variant sdgt_boson_Z also equals 1, and the whole family is collected by the master matching result match_rsbridge_rung.

(5) The declaration does not prove the physical mass of the Z boson, nor does it derive the rung value from the Law of Logic or J-cost functional equation; it only verifies that the constructor reproduces the legacy RSBridge table for this particle.

Aspects Recognition does not yet address:

  • Definition of compute_rung (imported from IndisputableMonolith.Masses.RungConstructor.Motif, whose source is not supplied in the given slice)
  • Any first-principles derivation of why bosons receive rung 1; the theorem is a verification statement only
