Every project here has a frozen protocol, a published result, and a simulation you can run yourself in the browser. Assumptions that change the answer are exposed as controls rather than buried, because a result you cannot stress is a picture, not a finding.
Model-based research, not investment advice and not a recommendation about any portfolio. Historical index returns are real; option prices are generated from realised volatility plus stated implied-volatility and skew assumptions. Taxes are not modelled unless a project says so.
