The Interior Observer Cosmological Framework: Paper 11 - RETIRED

SUPERSEDED — NUMERICAL RESULTS SHOULD NOT BE CITED Paper 11 subjects the Interior Observer (IO) cosmological framework to a comprehensive stress test against CMB perturbation theory, BAO absolute distances, and Big Bang nucleosynthesis. This paper is retained in the series solely to document the research path and methodology; the numerical results are no longer current. Paper 19 supersedes Paper 10's per-source projection architecture with a global boundary-Hamiltonian readout: H²ₒbs = √Δ × (8πG/3) (ρₘ + ρᵣ + ρ_Λ) − k/a². Revalidation of the six stress tests on the Paper 19 background (H₀ = 66. 33, Ωₖ = −0. 085) shows catastrophic failure of the CMB acoustic scale (θ* at 563σ), BAO distances (8. 4σ), P (k) (2. 9σ), and JWST ages (qualitative). Only Pantheon+ and age (by construction) survive. The dominant failure is traced to the open Schur N-slot. Revalidation is deferred until foundation items are closed. The kill shot methodology, Schur complement curvature formula, and boundary/bulk observable-class split remain valid contributions independent of the background branch. v1. 5 (March 2026): Paper retired. All content removed. Numerical results were computed on the superseded Paper 10 per-source projection background and with the contracting-phase cycloid parameterization (both now corrected). Surviving results (Schur complement curvature formula, species-dependent baryon correction concept) were incorporated into Papers 12, 19, 20 with corrected backgrounds. Earlier versions preserved on Zenodo for academic transparency. The IO framework publishes its errors alongside its successes. See Paper 21 v1. 1 for the full audit. v1. 4 - Paper 19 correction annotations. Abstract added with two founding premises. Per-source projection map and curvature projector superseded. Title page warning added: numerical claims of §§2–7 should not be cited as current. Dominant failure traced to open Schur N-slot. v1. 3 - Restored missing images. Converted to PDF. Unified title. v1. 2 - Baryon sector annotations per Paper 12 (BDP). fb = 2γ/x = 0. 313 supersedes fb = 0. 25. Rational baryon correction F = 1. 381 supersedes exponential F = 1. 623.
