E.17.ID.CR:5.4.5 - Product and design-review comparison case

Source slice. Two already available design-review notes describe the same integration boundary for the same planned release. One note foregrounds coupling and rollback pressure; the other foregrounds delivery simplicity and lower immediate implementation cost.

Comparative review unit. For architecture review, the first note foregrounds coupling risk more than the second, while the second foregrounds delivery simplicity and lower immediate implementation cost more than the first; that asymmetry is useful for discussion, but it is not yet a recommendation to choose either option.

Working-boundary use. This is the ordinary stay-here case: the shared review frame, bounded comparative lift, and outside-work boundary are already explicit, so the bounded comparative review move itself stays primary.

Why it stays here:

  • the same planned release remains the EntityOfConcernRef;
  • one bounded comparative lift is made explicit for a declared review task;
  • the unit helps design discussion without quietly becoming action selection or approval.
