UNDERSTAND THE RELATIONSHIP
A declaration makes an obligation explicit.
A contract describes the inputs, outcomes and requirements of an operation. That is a shared definition for the people and software using it.
IN A CONCRETE SITUATIONThe definition does not prove that every business implementation satisfies its intent. Handlers, integration code and meaningful tests remain necessary.

Configure identity and authority at the host boundary.
Adapters need the caller's authenticated context. Policy evaluation depends on the configured decision path; an annotation or a hidden control is not an authorization decision.
Where an operation explicitly requires approval, use the corresponding runtime and verifier. Scope, identity, expiry and storage guarantees depend on the mechanism you configure.

Take an operation that explicitly requires approval. Change one condition and inspect the expected path from the captured runtime guide.
Which request are you inspecting?
A CONCRETE SITUATION
Input preparation stops the path early.
The request omits an input required by the operation schema.
01 / INPUT
Parse and validate the request against the declared schema.
What changes
The request cannot become a valid prepared input.
What stays explicit
No visible button or descriptive tag makes the missing value valid.
FOLLOW THE CONSEQUENCE
A denial test for approval should use otherwise valid input, so it actually reaches the approval boundary.
A local decision record can help explain a result. Durable authority also needs an appropriate host, persistence and verification.
A receipt is useful when its relationship to the request, actor and permitted action can be checked. It does not independently prove every downstream provider effect or business outcome.
Source-informed presentation examples. The local website applies its own authored projections; the V9 source review inspected preference precedence, role independence, shell boundaries and reversible adaptation in ContractSpec.
Generated-artifact drift checks compare expected files with present files. They do not establish all semantic behavior. A source test definition is not a newly observed passing run.
A real runtime with fixture providers demonstrates its tested boundary. A live provider integration establishes only the scope and environment actually exercised.

Your deployment has its own operational responsibilities.
Your application remains responsible for infrastructure, secrets, provider accounts, business logic and the data it processes. Any managed application or support engagement has its own agreed scope.
