From 2f0e6e72b4311192cb6b3d1f30d6d0cda38b85f1 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 25 Jul 2026 22:33:44 +0000 Subject: [PATCH] docs: route the two-deflector lens_x2 system to the multi_galaxy package MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The prose called this system 'on the verge of group scale' and pointed at the group package — a two-co-dominant-deflector lens with no host halo is now precisely the multi_galaxy regime's exemplar; point there, with the group package framed one rung up the ladder. Notebook regenerated (catalogue unchanged by this prose edit).
