A.1.SCR:4.3 - Apply A.1 only when systemhood remains load-bearing
When the decision still depends on systemhood, recover all six A.1 constructive components. A.1 supplies the criterion.
| A.1 component | Practical recovery question |
|---|---|
| Exact entity | Which one entity is being tested, and what identity rule distinguishes it from its name, description, parts, environment, and successor? |
| Exact constituents | Which entities actually constitute it rather than merely being nearby, listed, sampled, or described with it? |
| Constructive part relations and assembly | Which obtaining part relations and assembly make these constituents this whole? |
| Reidentification rule | Which changes preserve it, and which replacement, disassembly, completion, or termination ends it? |
| Composition-grounded whole-level characteristic | Which characteristic follows from the actual assembly rather than from a label, plan, measurement, or one constituent? |
| Possible participation in a larger constructive assembly | Which boundary, interfaces, relevant characteristics, and identity-preservation conditions satisfy the applicable governed construction rule? |
Then apply the already admitted U.System condition: the whole has an actual physical or operational organization through which it can causally participate in Work or transformation while preserving identity.
