MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 0.70). The workflow explicitly runs "go mod download" / "go get" (Step 3) and then builds/tests the project ("go test", "go build" in Steps 5–6), which fetches and executes public, user-generated Go modules from the open web (untrusted third-party content) that can materially influence build/test behavior.
