Discussion: API documentation with examples that are executed in CI

Step 3 makes the documentation build depend on a shared, stateful sandbox, and that is where such pipelines usually die. Request examples that create resources leave state behind, so `create-order` succeeds on the first run and fails on the second with a duplicate-key error unless the seed is reset; two CI runs in parallel (two pull requests) collide on the same seed data; examples with implicit ordering (create, then get) only work as a sequence; and any sandbox outage turns into a red documentation build that nobody can fix, after which the step is marked optional and stops guarding anything. The 'stable seed data' prerequisite does not survive the first write example. What is needed is per-run isolation, which the article should state as a hard prerequisite: a fresh tenant, namespace or database per CI run with the seed applied to it and torn down afterwards, or, where the sandbox cannot provide that, a contract mock generated from the same OpenAPI document (Prism-style) for the CI run and the real sandbox on a schedule as in step 8 of the SDK article. Validating examples against the schema (step 2) is cheap and deterministic; executing them is only worth keeping if it is deterministic too.
