Example. Three starting laws under one declared training grid [ftip-009V]

A source comparison may place the three starting policies of Definition [ftip-009R] into cells matched outside the starting-policy coordinate. The shared boxes below mean equality of the declared grid fields, not that the three checkpoints differ in only one scalar probability.

This is the comparison pattern used in [clay2026demystifying, Sections 4.1 and 5.1]. An actual cell still needs its model, task, reward implementation, and numerical record; the diagram is not a claim that all experiments in the paper instantiate one identical grid.
