The diagnostic showed a '97.9% orphan rate' for months — alarming, motivating, and completely wrong. The real brain had 100% entity-link coverage; the orphan count was a measurement error from a script that didn't understand its own data. Worse, it was a stand-in for the metric that mattered: link-protocol discipline on new pages. The team optimized for the wrong number and called it progress.
