Problem: We have two independent spending minimums that need to operate in isolation: A usage-based charge with its own charge-level minimum A plan-level minimum commitment flooring all other usage fees When a charge-level minimum fires, it counts toward the plan commitment total, so the plan true-up never fires, even if no plan-related fees were incurred. Request: Add the ability to exclude specific charges from the plan commitment calculation — either via a per-charge flag (e.g. exclude_from_commitment: true) or an explicit include/exclude list on the commitment object.
