….3.20) Formalizes the G₂ metric journey results as certified Lean 4 theorems: - G2MetricProperties: non-flatness, spectral [1,10,9,30], det(g)=65/32 triple derivation, κ_T decomposition, PINN compression (25 theorems) - TCSPiecewiseMetric: building block asymmetry, H*(M₁)=dim(F₄), Fano automorphism PSL(2,7)=168, Kovalev eigenspace (30 theorems) - ConformalRigidity: Sym²=1⊕27, End=1⊕7⊕14⊕27, zero residual DOF (28−27−1=0), conformal exponent, J₃(𝕆)=N_gen³ (37 theorems) Zero axioms, zero incomplete proofs. Build: 2642 jobs, 0 errors. Blueprint updated with 3 new chapters, 380+ total certified relations. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The $\kappa_T^{-1}$ superscript in a \section{} title crashed
lualatex's hyperref bookmark processing (unicode-math conflict),
preventing the .aux file from being written. This caused ALL 378+
cross-references to appear as undefined.
Fix: wrap all math in section/chapter titles with \texorpdfstring{}{}.
