A.8:3 - Solution

Use the three-domain falsification test only after E.24.UK has admitted the candidate as a durable U-kind candidate.

The candidate passes A.8 only when all four conditions hold:

1. Distinct domain families. At least three projections come from foundationally different domain families.
2. Same abstract contribution. Each projection shows the same kernel contribution, not merely a similar word.
3. Non-trivial diversity. Each projection adds a non-trivial signal or bridge evidence not subsumed by the other projections.
4. Recorded losses. Differences, losses, and bridge risks are visible enough that readers can tell what is shared and what is local.

Use this compact record:

UniversalCoreProjection:
  CandidateUKind:
  UKindAdmissionResultRef: exact accepted E.24.UK output; follow it to the shared decision only when common inputs or decision mode are needed.
  DomainFamily:
  DomainTerm:
  LocalEoC:
  SameAbstractContribution:

  EvidenceRef:

Three records are the minimum evidence. Use them for a falsification attempt: if one projection changes the candidate’s abstract contribution, the candidate is not universal in the proposed form.
