+# Control-Loop Atlas
+
+This directory holds the canonical atlas narrative split by the original top-level sections from
+[docs/control-loop-atlas.md](/home/jan/projects/rrt/docs/control-loop-atlas.md).
+
+Use the compatibility index when an existing link only knows the old single-file path. Use these
+section files when adding or reviewing grounded narrative content.
