When a discriminator has no prior fact after explicit resets, both current sides
are applicable and equal, and the proposed target discriminator is unchanged,
KeepTarget, TakeSource or Candidate acknowledges only that discriminator.
It MUST NOT copy a constructor payload, acknowledge unselected descendants or
retire branch history. Descendant facets may be independently selected in the
same review; their decisions retain their own scopes and final-value audits.
Candidate records still MUST NOT change an unselected facet. Missing applicability
on either side does not qualify as an equal discriminator acknowledgement.
A grouped constructor resolution uses a transient typed target record, then
records the discriminator and each acknowledged descendant as separate facts.
It MUST NOT persist a second whole constructor payload overlapping those leaves.
