A.6.3.RT:5.4.d - Boundary to structure-to-narrative rendering

Source structure. Architecture candidate C-2 has module split M, data-custody constraint D, placement constraint P, and unresolved latency versus maintainability trade-off T.

Unsupported narrative. The team first tried to preserve M, then found that D forced P, so C-2 accepts latency residual T to preserve maintainability.

This adds an earlier attempt by the team, a discovery with the claim that D forced P, and a decision resolving the source’s still-unresolved trade-off.

Source-faithful reader ordering. To examine C-2, first consider module split M, then data-custody constraint D and placement constraint P; finally consider the unresolved latency-versus-maintainability trade-off T.

The source-faithful alternative orders the selected structures into a reader path; “first”, “then”, and “finally” describe that reading order, not a history of design Work. Apply A.6.3.NAR for ordering, connective account, preservation/loss, use, and source return. Use RT only for a remaining representation-scheme shift that does not depend on that narrative ordering.
