research_corroborate
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).

| sources | No | Restrict to a subset of sources: wikipedia, arxiv, pubmed, hackernews, duckduckgo. Default: all five. | |
| intent_token | No | Fresh single-use token returned by register_intent; required for this gated tool. | |
| freshness_days | No | Flag (do not drop) sources older than N days as stale so caller decides what to trust. | |
| min_corroboration | No | Only return claims asserted by >= N independent registrable domains (default 1 = include all). Set 2+ for cross-confirmed-only. |
