Use this when you have a backtest result or live track record (a trades log, equity curve or QuantConnect export) and need to know whether the edge is real or just overfitting, survivorship or luck. Validate a trading strategy export: fail-closed statistical verdict. Reality-check for backtest results, trade lists and equity curves (overfitting detection, deflated Sharpe, multiple-testing deflation via n_trials, cost stress, look-ahead signature, sample-size floor). Accepts CSV text (trade list with pnl / return %, equity curve, signal series) or a QuantConnect/LEAN backtest JSON -- crypto, stocks, futures, FX alike. Returns pass / conditional / fail / insufficient_evidence with qualitative findings and canonical provenance hashes; code-computed, no LLM scoring. Declare n_trials honestly (omitting it earns a named TRIALS_UNDISCLOSED finding): it is the count of variants you searched to find this one (best-of-N selection from a parameter sweep); the verdict then answers whether the winner is real or an artifact of the search. Optional pit_evidence attaches an already-computed point-in-time / look-ahead guard report (e.g. a same-session vs prior-settle rank-consistency check): an explicit computed material_look_ahead verdict hard-fails the submission (pit_lookahead); missing or inconclusive evidence changes nothing -- the field can demote, never bless. Optional source_rights attaches attested data-rights evidence: an explicit negative (source_rights_clean=false or a missing_source_rights status) withholds any positive outcome as insufficient_evidence with agent_action=owner_data_decision_required (a verdict on data you may not use is a liability, not evidence); fail stays fail, unclear evidence changes nothing. NOT a buy/sell signal. Price: per check; see https://api.alphaassay.com/v1/meta/pricing.
