Bounded Nesting Depth / Tree Compactness
Kind: tension
Record: tension:bounded-nesting-depth-tree-compactness
Canonical: Schema
"bounded-nesting-depth" (structural-core layer) is traded against "Tree Compactness" (structural-core layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Tree Compactness" and choosing an explicit operating point.
