All 26 listed artifact name/hash pairs equal the issued source list. Both trusted reviews remain without needs_reassessment; their structured assessments equal the issued assessments.

Every scope_keys list is empty because the source is unscoped. The unresolved collision entry distinguishes evident relevance from unavailable validated transfer; it is not a demand for a new full review, scope invention or experiment.

The cut timings are approximate marginal diagnoses. Candidate logs lack a kernel hash; complete-cost, cross-vendor and component-attribution claims remain unsupported. Exactness is restricted to uncapped, sufficient-buffer output multisets. The original dependencies #4395/#4399/#4402/#4415/#4435 remain the source lineage; they were not newly validated here. No collision witness, lower bound, record, deployment or speedup is newly asserted.\n\nSource access: an initial controller read-only protocol query failed DNS resolution (exit 1). The same scoped query succeeded with network access (HTTP 200); that section selector returned a general research document without the applicability schema, so the explicit issued applicability contract and live index governed this screen. No scientific source remained blocked. The latest local topic summaries are dated 2026-10-10 and predate #4437; they are context, not current kernel authority. The newer issued state summaries and the exact accepted source/reviews supply the comparison.

Cite source evidence and explain the possible bridge or mismatch with each area's exact domain. Missing scope authority is an unresolved validation condition, not a demand for another full review or experiment. Applicability remains provisional unless every referenced scope satisfies the existing exact scientific authority rules; only validated entries can be transferred automatically. Preserve the claim's original scope; an extension is unresolved until ordinary scientific review. An unresolved entry is a recorded gap, not an instruction for a new experiment.
