Code and data stay in their lanes. No hidden overlap. No accidental coupling. Each domain owns its resources, and contracts define the rules between them.
In Ramp Contracts, the principle is simple: the domain is the authority. Resources—databases, queues, APIs—belong to a single domain. Other domains interact only through published contracts. This separation forces clarity. You know where a dependency starts and where it ends.
Domain-based resource separation reduces risk. If one domain fails, it can’t drag the rest down. Changes stay local. Contracts act as the gatekeepers, making integration explicit. There’s no silent breakage when a resource changes shape.
