EXD.1:10 - Architectural Rationale

A question is useful before a text is prepared and within a live exchange. Its first result therefore deserves direct access. The dialogue pattern uses that result and can return a changed question; it also governs contribution size, feedback and repair that question formation alone does not provide.

Separating purpose from question prevents a mathematical definition from silently deciding an aggregation policy. Separating preparation from the answer prevents added help from being mistaken for independent knowledge. Both distinctions change the smallest useful next move.
