DOCA.3:10 - Rationale

Separating problem, proposed contribution, and acceptance expectation lets each be challenged without discarding the others. A receiving difficulty can remain valid when one delivery route fails. A contribution can be precisely described while its worth remains hypothetical. The distinction prevents both premature commitment and premature rejection.

An explicit confirming question gives provisional value a practical use. It says what the next answer would change instead of treating uncertainty as either permission to promise or a reason for indefinite research.
