The Library and SDK Question

A library design question asks you to define a reusable component that other engineers can integrate safely. Start by identifying the host, the supported use cases, and the behavior the library will guarantee.

For a recoverable operation library, an illustrative interface is:

initialize(config) -> readiness result
submit(request) -> accepted operation handle
observe(operationId) -> status stream
requestCancellation(operationId) -> cancellation result
close(mode) -> completion

These are conceptual signatures
