Learn · reusable decision methods
Use a clear sequence, inspect the supporting evidence, and leave with a template you can apply to the next task.
These are working checklists—not universal rules. Every method states when to use it, where it was tested, what it produces, and where its conclusion stops.
Three maintained methods
Each method links back to a real Case or Playground and includes a reusable Markdown artifact.
Review task fit, claims, evidence, uncertainty, and usability before model identity can influence the decision.
Turn sparse results into a decision without presenting labels, causes, or forecasts as observed facts.
Rebuild the arithmetic from source values, preserve intermediate precision, and accept the answer only when the path and result reconcile.
