- * Selection survival across the store seat (terminal design §4): the chat
- * store now carries what the per-scope selection account used to — this pins
- * the same behavior contract in the new mechanism. Drives the REAL
- * SlotsService store axis with the shared createChatStore handle (the exact
- * apply.ts shape: one handle, two session-slot registrations): same session's
- * two slots resolve one instance (conversation writes, details reads);
- * sessions are isolated; a session's death buries its instance AND its
- * persisted draft; a list refresh does not touch instance identity.
+ * Exercises selection persistence through the real SlotsService store axis;
+ * component stubs cannot prove per-session identity or disposal.
