Remark 7.1 · Registry after three returns: the theorem in characteristic \(p\) reduces to (A3a)(A3a) Rank-one models over O (Sakellaridis's Axiom 2.2.1): for every Borel orbit Y of maximal rank and every simple root α, the O-scheme YP_α/R(P_α) is one of the four standard PGL2-spaces over O, with his scheme structure on Y, and YP_α is the closure of its generic fibre minus the closure of the generic boundary.; audits launched
open audit: correct
Two agents proved the Cartan decomposition over \(\mathbb F_q(\!(t)\!)\) by different routes, and the close-field transfer gave Sakellaridis's theorem there modulo (A3a)(A3a) Rank-one models over O (Sakellaridis's Axiom 2.2.1): for every Borel orbit Y of maximal rank and every simple root α, the O-scheme YP_α/R(P_α) is one of the four standard PGL2-spaces over O, with his scheme structure on Y, and YP_α is the closure of its generic fibre minus the closure of the generic boundary. over \(W(\mathbb F_q)\). The direct rerun was relaunched after a failed first attempt, and the first auditor was assigned.
Independent evidence. The Cartan decomposition \(K\backslash X(\mathbb F_q(\!(t)\!))\simeq\Lambda_S^+\) was reached twice: by Delorme–Sécherre with a direct one-class lemma (Theorem 3.8), and by counting orbits over close fields (Proposition 4.5). Both agents also found that Chen–Yi prove their Prop. 17(i), the pages' input D0D0 · Orbit geometry over F̄_q, p ≠ 2 (Chen–Yi, Prop. 17, Thm 18): orbits indexed by Λ_S^+, closures, the support bound and the stabilizers., by citing results over \(\mathbb C\).
Decision. The open analytic Statement 6.3.1 is bypassed by the transfer, which uses Sakellaridis's theorem only over \(p\)-adic fields. The one input every route needs is (A3a)(A3a) Rank-one models over O (Sakellaridis's Axiom 2.2.1): for every Borel orbit Y of maximal rank and every simple root α, the O-scheme YP_α/R(P_α) is one of the four standard PGL2-spaces over O, with his scheme structure on Y, and YP_α is the closure of its generic fibre minus the closure of the generic boundary.. Launch the audit of A4 and A3 (agent A5).
