Module quota 

QuotaReductionPolicy — what to do when a parent’s quota reduction would drop below current child aggregate usage.

Default Reject — explicit opt-in is required for destructive policies. apply_quota_reduction is the standalone deterministic algorithm; parent-child wiring at Kernel::create_instance time composes around it.
