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

• Third-party content exposure detected (medium risk: 0.65). The required runtime workflow reads and ingests free-text from outsider-authored Markdown files (e.g., references/optimization-playbook.md, references/perf-knobs-catalog.md, references/cutile-api-reference.md) into the agent context as part of “Study related references” and “Select and apply ONE optimization”; these are not user-authored.
