Memorize the Error-Check Stack You Need on Most Decision Models
Recall a practical stack of error checks and when each one earns its place.
BCSR What does a compact model control stack need to cover? Think control coverage, not control count. Which check are you adding: integrity or source fidelity? They are not the same. A model can pass integrity checks and still misstate the source data after a bad mapping step. “We already have a balance check, so the model is safe.” A teammate resists adding a source tie-out.
