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

• Third-party content exposure detected (medium risk: 0.30). The runtime workflow described in SKILL.md/references/methods.md consumes an outsider-authored IFC validation MODEL (the STEP/IFC file itself) and parses its free-text-like STEP constructs for stage 2/3 checks, so attackers can submit poison IFC content that the pipeline ingests directly.
