1. AdjugateMatrix.lean — 2 sorry ⚠️ Q16_16 Obstruction
| Line |
Theorem |
Status |
Notes |
| 296 |
det_self_inverse_approx |
Open |
Q16_16 truncation causes 1 LSB error. Needs bounded-error variant or exact-div precondition. |
| 305 |
det_self_inverse_exact |
Open |
Pure integer-arithmetic proof under exactness hypotheses. Laplace cofactor expansion for 8×8 over ℤ. |
Note: The original det_self_inverse was refactored into these two variants. det_self_inverse_identity (identity case) was proven via computation.
2. HyperbolicStateSurface.lean — 1 sorry ⚠️ Q16_16 sqrt

Picard-Lindelöf existence |
Open |
∃ γ, IsSolutionND f x₀ γ. Requires C([-T,T]) as complete metric space + contraction mapping. File is in legacy/6point5sigma/, not in Compiler surface. |
