Phase 3 enrichment ran a sequential Neo4j query per fused result and the
final trim then discarded most of the output. Enrichment now covers only
results that can still reach the response - the Phase 4 rerank slice
(RERANK_SLICE_SIZE = 20, results beyond it are dropped when reranking)
or final_result_count, whichever applies - and resolves every page in a
single UNWIND $page_ids Cypher query via the new tenant-scoped
GraphService.get_related_documents_batch (per-page ordering by
shared_entities and per-page limit preserved via ORDER BY + collect()).
Unenriched tail results still carry related_dossiers: [] so the response
shape is unchanged. Query validated with EXPLAIN against the live Neo4j.
