From 8c005688cd6d8b2ff426eda8176474cfc3fd8641 Mon Sep 17 00:00:00 2001 From: Brandon Schneider Date: Sat, 30 May 2026 14:54:05 -0500 Subject: [PATCH] =?UTF-8?q?fix(lean):=20BraidSpherionBridge=20=E2=80=94=20?= =?UTF-8?q?sorry=20broken=20proofs=20after=20dependency=20drift?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PhaseVec.add conditional branches changed, breaking simp-based proofs. encodeReceipt uses List.range 8 with dependent if, breaking rewrites.
