Every portfolio below is a verifiable result. Open one and you get its historical performance recomputed from real, proxy-extended monthly data — with full provenance (data source, measured window, holdings), honest caveats (frictionless rebalancing, single historical window, proxy-extended history, statistical significance), and a reproduce-me config hash so anyone — or any AI agent — can re-derive the exact numbers.
Numbers are computed by a deterministic engine, never generated by a language model. Each result
page carries Dataset JSON-LD whose identifier is the reproduce hash and
whose disclaimer lists the caveats. The same config over the same window on the same
engine version always yields the same hash — across the site, the API, and the MCP tools.
Results update as new market data arrives; the reproduce hash encodes the measured window, so it stays honest rather than going stale.
