The research question
Does the model add information, or reproduce what the rest of the modelling process already knows?
A research-generation workflow for screening candidate mechanisms and keeping the search history visible to subsequent evaluation.
The technical work
Model development, feature handling, neutralisation and objective-aware evaluation.
The challenge is to connect the economic idea to a precise, reviewable experiment. Data transformations, the moment of a decision and the interpretation of the resulting return series all belong to that specification.
What to challenge
These are evaluation considerations for this domain, not a checklist presented as already passed.
- Time-aware splits
- Marginal contribution versus raw correlation
- Model and dataset version tracking
- Adaptive search counted in the evaluation
The data boundary
Versioned modelling datasets with documented targets, eras and platform evaluation rules.
Descriptions are intentionally high-level. Parameters, execution rules and non-public source data are not published here. Withholding an implementation is different from overstating its evidence.
The interesting question is not whether a backtest looks good. It is what would have to be true for the result to mean something.
