Production scores come from _rescore_submission, which re-reads evidence via
_domain_evidence_from_ui and re-scores. Serialization dropped the promoted /
entity fields and the precise EvidenceSource, so on every rescore Naver
promotion (+40) and Google web-entity (+40) silently scored 0 and skip
evidence was mis-restored as FAILURE (+30 phantom).
- store_serialization: persist domainSource / promoted / promotionReason /
entity / category in _evidence_payload and restore them in
_domain_evidence_from_ui; resolve the source from the persisted enum
(keyword heuristic kept only as a legacy fallback).
- search_result_promoter: structural no-result detection (covers image/blog/
web variants), scan only result fields not the query, add Korean rights
markers (excluding over-generic substrings).
- risk_scoring: dedup promoted Naver hits by query_signature; drop zero-point
skip reasons from the operator-facing reasons list.
Tests: round-trip regression (promoted naver / web entity / two distinct
entities score > 0; skip adds no phantom points) + skip-reason exclusion.
