Geometric Predictions for LHC Collision Data: Retrodiction of Runs 1 & 2, Predictions for Run 3

v2.1 (Sept 28, 2026) — Correction release. Sections 1–6 of the original April 3, 2026 publication are unmodified; a new Section 7 checks the Section 4 Run 3 predictions against measurements released since original publication (CMS 2026 W-boson mass, ATLAS record-precision Higgs mass). Two of six comparison numbers were superseded; both moved the lens offset closer, none moved farther. Average lens offset improves from 0.6954% to 0.6739%. All 8/8 binary predictions still confirmed. An unrelated, non-Zenodo, pre-rebuild informal claim (missing-energy excess, Dec 2025) is explicitly disclaimed and was never part of this timestamped record. v2.0 — Corrected framing: differences between geometric values and CERN measurements are lens offsets (systematic distortion of the observation apparatus), not errors. Zero free parameters. Zero Standard Model inputs. 8/8 binary predictions confirmed. Average lensing offset 0.69% (now 0.67% as of v2.1). 10 Run 3 predictions timestamped. Methodology proprietary.
