Every organization runs on maps - profit and loss statements, performance reviews, strategic frameworks. These maps compress reality into something manageable. The compression is inevitable. Scale demands abstraction.But maps always erase something. And what gets erased is often what matters most: prevention work that manifests as silence, multiplicative value that defies attribution, craft that compounds invisibly, judgment that refuses to fit the form.The standard literature offers aspiration. This book offers mechanics.The Cage and the Mirror explains why the erasure is structural, not cultural - why it persists regardless of leadership quality, survives every process improvement, and intensifies as organizations scale. Drawing on Gödel's incompleteness theorems, information theory, corporate law, and two decades inside organizations under pressure, it reveals why the Cage is not a problem to be solved but a physics to be navigated.This is not a book of solutions. It is a book of sight.Excellence requires variance. The Cage eliminates variance. Therefore, the Cage eliminates excellence.
