All numerical tests were executed against the live production API at maisner.eu. Reference values were computed independently in Python using standard scientific libraries (NumPy, SciPy) without access to the platform's internal source code paths — only the public API contract (inputs → expected outputs) was used.
For each test, an acceptable tolerance was defined based on floating-point rounding in the API response (typically ±0.01%). Tests involving Monte Carlo simulation (liquidation probability, CVaR) are marked with a wider tolerance band and a fixed random seed for reproducibility. Formula identifiers reference the MAISNER Methodology document (maisner.eu/methodology).
Multi-asset portfolios of 20–22 instruments were used where possible to stress-test numerical stability under realistic conditions. Edge cases tested include: near-singular covariance matrices, single-asset portfolios, zero-weight assets, unresolved tickers (silently dropped with weight renormalisation), and extreme parameter values (k=2.5, T=90d, α=0.99, L=3×).

| BF35-02 | BUG FIX: PSR formula uses monthly SR (per-period), not annualized | Bailey & López de Prado (2012): PSR = Φ(SR_hat / sigma_sr) where SR_hat is per-period (monthly) Sharpe and sigma_sr = sqrt((1−sk×SR_hat+(ku-1)/4×SR_hat²)/(T−1)). BUG: code used SR_ann (×sqrt(12) larger). FIX: sr_monthly = (mean(oos_rets) − rf/12) / std(oos_rets, ddof=1). Synthetic test T=24, mean=0.008/mo, std=0.030: sr_monthly=0.1682, sr_ann=0.5826, sk=−0.427, ku=2.386. PSR_correct=0.781. PSR_wrong=0.9916. Diff=0.2106. Fix eliminates inflation. | formula correct | PASS |

| BF36-01 | BUG ANALYSIS: Vasicek daily returns × freq=12 → 21× return error | Govt bond: coupon=4%, mod_dur=4.5y, y_vol=0.007/√252 per day. Daily price return ≈ −4.5×dy. Annual vol from daily: 4.5×0.007=3.15%. If freq=12 applied to daily returns: mu_monthly=mu_daily×12≈0.19%/yr instead of 4.0%/yr (=mu_daily×252). Error factor=252/12=21×. Vol error: std_daily×sqrt(12)=0.68% instead of std_daily×sqrt(252)=3.15%. Error factor=sqrt(252/12)=4.58×. Bond optimizer weight would be massively underestimated due to ~21× return understatement. Verified analytically. | analytical | PASS |
| BF36-02 | FIX: Monthly Vasicek (dt=1/12) preserves annualized vol | Before fix: dt=1/252, n_steps=504 → 504 daily returns, carry=coupon/252 per step. After fix: dt=1/12, n_steps=120 → 120 monthly returns, carry=coupon/12 per step. Annualized vol consistency: annual_sigma=y_vol×mod_dur=0.007×4.5=3.15% for govt bond. Monthly std=annual_sigma/sqrt(12)=0.91%. Daily std=annual_sigma/sqrt(252)=0.198%. Both produce the same annualized vol when scaled by sqrt(12) or sqrt(252) respectively. min_len=min(119_monthly_equities, 120_monthly_vasicek)=119. freq=12. Correct scaling. Verified with synthetic Vasicek path. | vol preserved | PASS |
| BF36-03 | REGRESSION: Multi-asset optimizer with bond + equities still produces valid weights | POST /api/optimize/multi-asset with AAPL+MSFT (equities) + 5yr Govt bond (4% coupon, AAA). weights sum=1.000, all ≥ 0, no NaN. Before fix: bond weight near 0% (21× underestimated return → penalized). After fix: bond weight >0 and proportional to its risk-adjusted return. Weights: AAPL+MSFT combined <100%, bond >0. No crash, no 500 error. Verified post-deploy. | no crash; bond >0% | PASS |

| EFA38-08 | PSR (Probabilistic Sharpe Ratio) formula audit — Bug #23 fix confirmed | backtest_engine.py PSR uses sr_monthly=(mean(oos_rets)−rf/12)/std(oos_rets,ddof=1) [per-period, NOT annualised]. sigma_SR=sqrt((1−sk×SR+(ku_raw−1)/4×SR²)/(T−1)). With ku_raw=fisher=False (raw kurtosis, normal=3), (ku−1)/4=(excess_ku+2)/4 matches Lopez de Prado AFML eq.15.2. For normal distribution: sigma_SR=sqrt((1+0.5×SR²)/(T−1)), which is correct per AFML. Code consistent with Bug #23 fix (was using annualised SR, now uses monthly). Formula verified correct. | formula audit | PASS |
