Partitioning / Rebalancing Complexity
Kind: tension
Record: tension:partitioning-rebalancing-complexity
Canonical: Schema
"partitioning" (performance-core layer) is traded against "Rebalancing Complexity" (performance-core layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Rebalancing Complexity" and choosing an explicit operating point.
