Consequence

The number on slide 4 that was last quarter's.

Accuracy only matters where the error has a consequence: a client, a regulator, an auditor, a board. In those reports one stale number costs more than the whole reporting process.

How it shows up

A chart nobody touched still shows the old period
The text says 4.2 percent, the chart shows 3.9
Two versions of the deck in circulation with different numbers
A report generated for the wrong client that looks perfectly correct

Why it keeps happening

Copied numbers have no address. A reviewer can check that a number looks plausible; nobody can check that it is the right one without going back to the source, and there are 300 of them. As generated output gets more fluent, a wrong number gets more convincing.

What fixes it

A bound number can be pointed at. The reviewer sees which cell or query it came from, the auditor can follow the line back, and Refresh brings every number through the same link so the text and the chart cannot disagree. Rules by value do the checks people forget: a breach is red, an empty section is dropped.

The test

If you cannot tell, for any number on any slide, which cell or query it came from, the deck is copied, not linked. Everything else follows from that.

FAQ

Questions people ask before they try it

Does this stop a wrong rule?

No tool can. What binding does is make the rule visible and inspectable, so a person who cannot read code can still see what the number is and where it came from.
