Idempotency / State Tracking
Kind: tension
Record: tension:idempotency-state-tracking
Canonical: Schema
"idempotency" (atomic-boundary layer) is traded against "State Tracking" (atomic-boundary layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "State Tracking" and choosing an explicit operating point.
