+Current bounded state blocks:

+- session globals at `0x006d40d0`
+- active session-event transport at `0x006cd970`
+- preview dataset at `0x006cd8d8`
+- Multiplayer window backing block at `0x006d1270`
+- selector-view store rooted at `[transport+0xab4]`
+
+What this note is for:
+
+- Multiplayer window and preview-dataset ownership
+- Session-event transport routing
+- GameSpy-facing callback and live-route semantics
+- Selector-view refresh, retry, and probe state
+
+Highest-value open edge:
+
+- The remaining owner-side callback roles behind the validated GameSpy packet branches and the
+  exact user-facing meaning of the selector-view sample or companion fields.
