 * Tokens: every verdict-bearing call replaced a look the agent would otherwise have taken as a
 * screenshot. The tokens Reticle actually returned are subtracted, so the figure is a NET saving
 * and can never exceed the modelled cost of the runs it replaced.
 *
 * Minutes: two different counterfactuals, summed. EVERY verdict replaces a check somebody would
 * otherwise have made by hand. A verdict that also caught a DEFECT saves the re-prompt round trip on
 * top, because that is what a false green costs when it escapes.
 *
 * Decomposed rather than blended so the basis line can name both, and so changing the value of a
 * pass never silently changes the value of a catch.
