# ContractResponsiblePartyV2

One responsible-party window on a contract. Both bounds are inclusive. Windows do not overlap, with two exceptions: two windows may meet on a single shared day (one window's `endDate` equal to the next window's `startDate`), and a window whose `startDate` equals its `endDate` is a retired record rather than a live one-day assignment. To resolve who is responsible on a given day, ignore windows where `startDate` equals `endDate`, and on a shared boundary day prefer the window that starts that day over the one that ends it. The current window is the one with no `endDate`; there is at most one per contract.

        day over the one that ends it. The current window is the one with no
        `endDate`; there is at most one

        per contract.
