Erratum Compendium (June 2026): Papers XIII, LVIII, LXXII, LXXX, CXV and Supplement Rev. 2 - with Paper LXXX v2 (Photon Sphere as Critical-Coherence Surface)

One-Octonion Brane-Bulk Series. Erratum Compendium from the 299-paper multi-model review (GPT-5.5, Gemini-3.1-Pro, Nemotron, Claude; DeepSeek adjudication), reconciled against Audit v2.4 and Lagrangian Foundations v2; every finding independently re-derived before registration (verify scripts bundled; 22/22 + 16/16 PASS). E1 (Paper XIII + Supplement Rev2 SC.2): [e1,e2,e3]=+2e7 is impossible (H+ quaternionic implies associator 0); confinement identity [e4,e5,e6]=-2e7 verified; corrected chirality = associative vs non-associative sector (STRONGER). E2 (LVIII): sigma=0.18 GeV^2 unit-label fix (Regge alpha'=0.884 GeV^-2 CONFIRMED); T2* radii/splittings retracted (galactic a0 transplanted into hadron - open problem). E3 (LXXII): Silk-damping suppression was a category error (nu=-1 governs brane modes, not photon diffusion); sign and alpha_s scale-label fixed. E4 (LXXX): monodromy photon-sphere algebra withdrawn and REPLACED by Paper LXXX v2 (bundled): photon sphere = critical-coherence T2* surface (gamma_phi = 1 exactly, lambda_L = Omega); monodromy relocated to spin-2 (Motl-Neitzke factor 3 = three Fano lines through e7; photon factor trivial - why the original could not work). E5 (CXV): exclusion set corrected to the crystallographic restriction q in {1,2,3,4,6}; q=7 remains excluded - the Z7 hiding claim SURVIVES STRENGTHENED. Community: one-octonion-brane-bulk.
