From ddd9f81f5a71d75682462c0a84645ea4f84ae18e Mon Sep 17 00:00:00 2001 From: Paul Lizer Date: Sun, 11 Oct 2026 10:25:40 -0400 Subject: [PATCH] Add reference-based Word and PowerPoint transformations Integrate native document inspection and separate create-from-reference and refresh tools into Gather/Reason/Render. Preserve source packages, deliver useful drafts with committed outcome reports, and support same-conversation artifact revisions. Add template intake, regression coverage, documentation, and version 0.261.321.
