From 016369c3ce85bc521f273deff19b12535a82192c Mon Sep 17 00:00:00 2001 From: Allaun the Fox Date: Sun, 28 Jun 2026 15:54:10 +0000 Subject: [PATCH] cherry-pick: import AdjugateMatrix, ColdReviewer, RollupEvent from Research-Stack MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - AdjugateMatrix.lean — 8x8 matrix adjugate, determinant, identity - ColdReviewer.lean — unified cold-review formula (Psi_inv, Psi_gap, Psi_Sidon) with dec_trivial proofs (no native_decide) - RollupEvent.lean — Oracle rollup verifier with Prop/Bool bridge, soundness theorem, byte serialization - lakefile.lean — register new modules under SilverSightRRC - nr_bracket_validation.py — resolve merge conflict (paths + inits) All native_decide calls replaced with dec_trivial per project policy. --- formal/SilverSight/AdjugateMatrix.lean | 62 ++++ formal/SilverSight/ColdReviewer.lean | 115 ++++++++ formal/SilverSight/RollupEvent.lean | 379
