Performance and Scaling

Performance advice is only useful when it points to the real owner of the bottleneck.

Operating Rules

• optimize only where contract validation or core transforms are demonstrably hot
• do not blur durable semantics for speed
• runtime-level tuning belongs in runtime unless the contract layer itself is slow
