Executive Summary. Internal quantitative validation of all MAISNER platform engines. Each formula was verified independently: expected values computed via Python reference scripts with no shared code paths, compared against live API responses. All 779 tests passed within stated tolerance. This report covers mathematical correctness only — formulas, coefficients, and numerical outputs across 36 modules. Non-mathematical tests (auth gates, crash guards, structural field checks) are documented separately in test_security_full.py.

Validation Methodology

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×).

35 PSR Formula — Monthly vs Annualized Scaling (Backtest, Protocol v2) 2 / 2 PASS
Protocol v2. PSR (Probabilistic Sharpe Ratio) formula verification: Bailey & López de Prado (2012) requires per-period (monthly) Sharpe in the test statistic, not annualized. Using annualized SR inflates PSR significantly (e.g. PSR 0.99 → correct 0.78 for T=24, SR_ann≈0.56). Verified against independent Python implementation.

BF35-02BUG FIX: PSR formula uses monthly SR (per-period), not annualizedBailey & 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).

36 Bug Fix 2026-05-27 — Multi-Asset Optimizer: Vasicek Bond Synthetic Frequency Mismatch 3 / 3 PASS
Protocol v2. Bug in multi_asset_optimizer.py _optimize_linear(): Vasicek bond synthetic returns used daily dt=1/252, n_steps=504, producing 504 daily-frequency log-returns. When mixed with equity price histories from price_history.xlsx (~119 monthly log-returns), min_len=119, freq=12 was applied to all series. Bond daily returns were treated as monthly: expected_return understated by ×21 and vol understated by ×4.6 (sqrt(252/12)=4.58). Fixed: dt=1/12, n_steps=120, monthly carry = coupon_rate/12. Annualized vol preserved: daily_sigma×sqrt(252)=monthly_sigma×sqrt(12)≈3.1% for government bonds.
IDComponentFormula / RuleToleranceStatus
BF36-01BUG ANALYSIS: Vasicek daily returns × freq=12 → 21× return errorGovt 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.analyticalPASS
BF36-02FIX: Monthly Vasicek (dt=1/12) preserves annualized volBefore 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.

Scope limitation. This report covers mathematical correctness of numerical outputs only. It does not constitute a security penetration test, a data quality audit of third-party price feeds (FMP Professional, Polygon), or a regulatory compliance assessment. The tolerance values reflect standard floating-point rounding in API JSON serialisation (2 decimal places for percentages, 4 for ratios). Monte Carlo results are stochastic by design; those tests are marked with wider tolerances and were run at least three times to confirm stability.
