C.2.8:10 - Architectural Rationale
The three-bearer definition explains why the same account can support different structural recoveries. The episteme distinguishes a content change, the form distinguishes expression, and the observer distinguishes who or what can extract the structure. Qualification conditions make comparison possible without inventing a new bearer for every resource limit.
Articulation explicitness, structural amount and task adequacy answer different questions. A plan can state its action condition completely while its reader lacks the prerequisite procedure. A diagram can expose additional relations while remaining insufficient for a design decision. Keeping these results separate preserves both the useful gain and the precise next question.
A common definition also allows unlike estimators without claiming universal commensurability. A path count and a justified coding estimate can address structural-information questions; their values are comparable only under an adequate scale and correspondence. The source studies therefore inform the aspect and its conditions while domain methods establish the particular result.
