SYSE.22:9 - Consequences
The project can change both what it is solving and what Systems it considers without discarding lineage. Useful stepping stones remain recoverable, stale comparisons become visible, and one bounded probe can be chosen while the problem and System family remain revisable.
The cost is maintenance of identities and decision-bearing correspondences. Some cells remain unresolved, and the best current result may be a probe, rejection, or reroute rather than a selected System variant.
