+## Abstract in the source's own vocabulary
+
+*(Fill after first full pass — no Soul Frame terms yet.)*
+
+## Why selected for Soul Frame
+
+```text
+Relevance:
+  Consciousness-centered evolutionary/developmental account of mind-like
+  phenomena. Direct pressure test for Soul Frame's choice to decenter
+  consciousness as the interop criterion of Beinghood while still needing a
+  disciplined place for Bewusstsein-talk.
+
+Risk (collision / scope creep):
+  High terminological collision around Bewusstsein, Geist, evolution.
+  Risk of absorbing a consciousness theory Soul Frame explicitly postponed.
+  Keep Step 2 (internal reconstruction) strict.
