A SMALL, BOUNDED, in-Worker sanity-check backtest — NOT a full-universe backtesting engine. Answers a quick question like 'does this factor actually work on these 5 names over the last year' inline, mid-conversation, without leaving MCP. Composes two existing tools (`get_pit_universe` + `get_pit_valuation_ratios`) across up to 10 tickers x 12 rebalance dates (120 cells): for each rebalance date, checks which requested tickers were in the survivorship-free PIT universe on that date (dropping — never erroring on — a ticker not yet listed or already delisted), then pulls each surviving ticker's point-in-time valuation multiples and computes the forward return to the NEXT rebalance date from the raw (unadjusted) close. Returns a flat {rebalance_date, ticker, factor_values, forward_return_pct} grid plus a small factor<->forward-return correlation per requested factor — a quick cross-sectional signal check, NOT a transaction-cost-aware portfolio simulation or a statistically validated backtest result. If the requested grid exceeds 120 cells, this tool does NOT silently truncate — it returns a `stream_fallback` response (signed Parquet download URLs, same shape as `get_compute_ready_stream`) and tells you to use those URLs. For a REAL full-universe, multi-date, survivorship-free backtest, use the Python SDK's AlphaEngine (`pip install valuein-sdk`) looped over `as_of` dates client-side — this tool is explicitly the small complement to that, not a replacement for it. Available on every plan; coverage follows your plan tier same as the two tools it composes.
