E2 invariants verified:
- Cross-provider automatic merge: DOI/arXiv base only
- Title-only similarity: never auto-merges
- Provider-specific aliases: local merge scope
- arXiv versions: retain version IDs, share base identity
- Strong identity disagreement: IDENTITY_CONFLICT preserved
- Disjoint provider dates: DATE_CONFLICT, no canonical consensus date
- PARTIAL/FAILED provider coverage: never no_match_found=True
- Aggregation confidence: evidence confidence, not novelty score
- Sealed TCFT-BTAP core conformance remains unchanged
