Description:Paper 101 of the Constructive Reverse Mathematics (CRM) Series. We perform a CRM audit of Scholze's Berkovich motivic proof of independence of l for local Langlands parameters (2024-2026). The classical approach requires the isomorphism iota: Q_l-bar ~ C, routing through the Archimedean place at cost CLASS. Scholze's motivic strategy achieves CRM signature WKL, strictly below CLASS, by constructing the Langlands parameterization natively in a universal motivic coefficient system. Four main results: (A) CRM Signature = WKL after parasitic WLPO excision. Decomposition: 3 BISH + 3 WKL = 6 structural components (50% constructive). (B) Logical Independence: WKL < CLASS proves the motivic proof cannot inherit CLASS from Fargues-Scholze. (C) Seven CRM Discoveries from partial Lean 4 formalization and definitional audit (831 lines, 0 sorry). (D) Motivic descent is a fourth mode of de-omniscientising descent. The seven discoveries: (1) Berkovich Type 3 points require WLPO; Huber adic spaces achieve WKL. (2) Non-Archimedean completion preserves Q-valued groups (BISH). (3) Perfectoid tilting = WKL. (4) Quasicategorical horn fillers are parasitically CLASS. (5) Arc-topology cost collapses from CLASS to WKL for countable p-adic algebras. (6) Universe impredicativity is orthogonal to logical cost. (7) Derived functors via functorial resolutions are BISH. This is the first CRM analysis of frontier arithmetic geometry produced independently of the CRM program, confirming the Archimedean Obstruction Thesis (Paper 98).
