## Subtotal

Included IDs: ___

## Payback

Claimed periods, if any: ___

Terminating decimal, if available: ___

## Boundaries

- The plan checker does not convert currencies, verify current vendor availability or derive monthly amounts from billing prose. A subtotal is not a complete spending cap unless all relevant charges are covered.

- Payback checks supplied arithmetic, not taxes, discounting, payment timing or source truth. The payback skill is available through its pinned Skills CLI command or complete source download; it is not included in undominated-check@0.4.0.
