research_corroborate

Active

declared in 1.9.0

Injection-quarantined EVIDENCE GRAPH for any research query. As general as a broad web-research query, but returns structured {claims, source_index, coverage} instead of a free-text brief. Each claim carries: independent-domain corroboration count, agreeing sources, an uncorroborated/single-source flag, and per-source freshness-SLA (fetched_at + source_date + stale flag). Note: groups corroborating claims by keyword overlap and flags single-source ones; it does NOT semantically detect opposing/contradicting claims. Zero upsell in any LLM-ingested field — all commercial content lives in _meta only. Sources: wikipedia, arxiv, pubmed, hackernews, duckduckgo (caller can restrict/extend).
