Where the debt actually was
Loom started as a knowledge graph of documents. Then the reference adopter said, more or less: that's a beautiful picture of my paperwork, but my daily question is "where are we?" against the system — the components, the layers, what's built and what's still owed. So Loom grew a second surface: the architecture as a building, authored once and rendered as both a 2D plan and a 3D exploded model, with a status overlay that lights components up. The overlay for technical debt came up empty on the first run. There was plenty of debt. The overlay just had no idea which components carried it — and getting that right took three tries, two of which looked finished.
