The contract vehicle this order was placed against (IDIQ, GWAC, FSS, BPA)

Resolve an order to its parent vehicle.

Most federal services work is not bought as a standalone contract: it is a task order placed against a vehicle you must already hold. 6.18M of our contract rows carry a parent_award_id_piid, so for those the actionable question is not "who won this" but "what would I have needed to hold to bid at all".

Three outcomes, deliberately distinguished, because collapsing them into one 404 would tell the customer nothing: standalone - the order has no parent; it was competed on its own. resolved - we hold the parent vehicle; it is returned. not_in_corpus- the order names a parent we do not carry. Honest, not a 404: the order exists, the vehicle is simply outside our coverage.
