+/// The complete SWOT analysis, as the result view shows it and the chat stores it.

+/// <remarks>
+/// The assistant keeps its result in its session state, which compares objects by reference since
+/// the mirror instance takes over only what changed. Therefore, replace a result as a whole and never
+/// change it in place: a change in place would not reach an instance the user returns to.
