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

• Third-party content exposure detected (high risk: 0.90). The workflow mandates "MCP Ref Research — per shared/references/research_tool_fallback.md" (Phase 3) which explicitly defines an MCP Ref → Context7 → WebSearch fallback chain, and those external/web search findings are parsed and used to auto-correct and edit plan/story files, so the agent ingesting public web content can materially influence actions.
