+## Launch prompt
+
+```
+/goal next — drive the roadmap to its next frontier item.
+
+Per project memory (session 0005, machine-altered-perception design SPEC merged
+to main via PR #4), the roadmap frontier is sub-project 3: the player /
+machine-alteration engine. This coding session builds that.
+
+```
+
+## Deferred decisions
+
+_Autonomous-mode low-confidence calls the driver made and would have
+liked operator input on. Appended as the session runs; surfaced at
+finalize. Empty if none._
