A team reviews whether this workflow isolates parallel agent validation for separate services in a monorepo. Evaluate the following statements. 1. The concurrency group isolates cancellation per pull request. 2. The matrix configuration prevents service jobs from running in parallel. 3. The artifact settings separate evidence for each service scope.
