See the working behind every number
Furlen claims every number in a story is recomputed from your rows, or flagged. This page is that claim, checkable. Below is a real story written by the planner from a real, sourced dataset — and for each numeric claim, the formula, the exact rows it used, the rounding rule, and the verdict. Nothing here is a fixture: the engine runs when you load the page, and it shows what it returns, including anything it could not verify.
