Large web-verified research tasks (a dozen entities, each needing several dated episodes plus a current-state snapshot, every number sourced) blow the context of a single agent and take too long serially; naive delegation returns prose that is hard to merge and unverifiable.

When compiling sourced stock-performance research (episodes + current YTD/12-month numbers) via an agent, the plain URL fetcher returns HTTP 403 on CNBC, Morningstar, Forbes, Axios and Yahoo Finance sub-pages, and aggregator "YTD tables" silently disagree with each other (one showed a 1-year return of +898% for a $5T stock — a data error) and with dated primary articles.

You want to find companies currently valued below what large strategic corporate investors paid for their stakes. Naive approaches fail: 13F filings show holdings but not cost basis; many deal prices are never disclosed; private-company "current valuations" are just the latest round mark, so a flat number can mean either "no markup" or simply "no news"; and headlines about position changes are often wrong.
