Pure refund math for the 5.1 refund contract. No node, no scene dependencies — embed it in a RefundService, a custom Refunder, or any consumer script. Given a resolved BuildCost, computes id -> refund amount at refund_ratio and optionally applies it to a container through the canonical id interface (try_add_by_id).

| Name | Kind | Summary |
|---|---|---|
refund_ratio | Property | How fractional refund amounts are converted to whole items. Fraction of the original cost returned on demolish (1.0 = full refund). Values above 1.0 would pay more than the build cost, so construction clamps them to 1.0 with an error; negatives produce no refund. |
rounding | Property | Rounding policy applied per entry after the ratio multiply. |
