The seat keys a consumer's provisions from its wanted and newest builds but keeps the plan of its wanted build alone, and the provider helper bound only from plans: a requirement the newest build adds stayed asked with no word, and the want waiting for it never moved (mcp-endpoint on ace and shanks). A provision now carries the plan entry it was composed from; the helper binds from it where no plan names the key, the plan winning where both do, and says each key it can bind from neither (issue 1126 review 1).
