+    what follows from them. Dewey's diff c6bd1f1e matched Filbert's own
+    regeneration. His two observations are accepted as written. The P3 rule
+    disables every Pi dialog, which is wider than CHAT-01, but no dialog can
+    reach the controller without explicit extensions. Sage committed the
+    brief, the earlier rounds and the six review reports. Sage names the
+    source author after queue A2 lands, so Darkwing isn't split between
+    them. The code may not start before then.
