EXAMPLES
BOUND in concrete system shapes.
These examples are intentionally small. They show how to turn a system responsibility into a boundary, an observable contract, an execution surface, and verification evidence.
REST serviceHTTP ownership, request/response contracts, compatibility, and contract tests.Event-driven systemProducer/consumer boundaries, event schemas, ordering, retries, and delivery verification.Shared databaseExplicit state ownership and the boundary problems created by direct shared persistence.
Executable fixtureMachine-readable agent handoff with deterministic verification evidence.
Reading rule: the examples illustrate the method; they are not prescribed architectures. BOUND does not require REST, events, or database isolation as an architectural choice.
