From e64138ef2c02138719b1bca0bbaea9af8f433d98 Mon Sep 17 00:00:00 2001 From: jgrusewski Date: Wed, 18 Mar 2026 21:03:09 +0100 Subject: [PATCH] fix: liquid adapter dangling code + stale checkpoint comment MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Removed dead code after early return in liquid round-trip test. Checkpoint is implemented — removed "Skip weight equality check until checkpoint is implemented" comment. 12/12 lightweight smoke tests pass. 6 heavy tests need >4GB VRAM (H100).
