A task is routed with POST /api/v1/harnesses/route over openvibe-sdk/placement, which picks an offer from this catalog: hard requirements first (a capability the task needs), then cost. The catalog is read and validated when Codes starts; every price and limit is as the offer states it. Machine-readable: GET /api/v1/harnesses.
