• regimen_describe_factors

  List the market-condition factors Regimen slices performance by, with units, the upstream operation each is read from, and how it is bucketed. Call this when you need to know which factor keys exist or how to explain a bucket to a user. Takes no arguments, reaches no network, never changes.

• regimen_evaluate_track_record

  Answer whether a trading strategy’s measured performance is distinguishable from luck. Returns the Probabilistic Sharpe Ratio (the probability the true Sharpe beats a benchmark, corrected for sample length, skew and fat tails), a bootstrap confidence interval, and the Minimum Track Record Length — how long the record would have to run before the claim could be made at all. Use this whenever someone quotes a Sharpe ratio, a win rate or a return and you need to know whether the number means anything. It will frequently say the evidence is too thin; that is the intended answer, not a failure.

  shallow
• regimen_regime_map

  Break a strategy’s returns down by the market conditions that held on each date — volatility, funding, open interest, positioning, sentiment, trend state — and report performance per bucket. Each factor also gets a permutation test: the observed best-to-worst spread is compared against spreads produced by randomly reshuffling the regime labels, so a flattering subset cannot pass itself off as a regime effect. Use this after regimen_evaluate_track_record when you need to know WHERE an edge comes from, or whether it is a bet on conditions that could end.

  shallow
• regimen_self_attack

  Run Regimen’s own analysis against controls whose answer is known in advance: the strategy’s returns with the edge mathematically removed, and a simulated population of strategies with no edge at all. Returns whether the engine correctly found nothing in them, and where the real strategy’s confidence sits among pure-luck strategies of the same length and volatility. Use this when a user is entitled to ask why they should believe the verdict, or before quoting a result as evidence.
