Predict First · flowbudget bundle Use before changing code whose success is a measurement, not a passing test - trading strategies and backtests, ML models, simulations, numerical solvers, performance tuning, data pipelines. Makes you write numeric predictions first (including one against the change), try the change as a temporary patch without editing the repo, and judge it against the predictions before any edit. Trigger on "does this fix work", "will this improve", "let's try", "backtest", "tune", "the numbers are off", or any proposed change to a model, strategy, or solver.
