  "notes": [
    "Height/weight conflict: Kepler's own PR Newswire releases (Oct 2024 and Aug 2025) do not give a consistent single figure across all Kepler materials; several secondary aggregator sites (e.g. humanoid.guide-derived listings) report 178 cm / 85 kg instead of the 175 cm / 75 kg used here. The 175 cm / 75 kg figure is used because it traces to Kepler's own named press release with a direct quote; the 178 cm / 85 kg figure could not be traced to a specific dated primary source and is not used.",
    "An earlier press round (April 2025, SAIC-GM Shanghai plant deployment) and independent coverage cited a $30,000 USD base price; this is not included as a price_history entry because it could not be traced to a specific dated Kepler statement during this build, and it conflicts with the ¥248,000 pre-sale price from the Aug 2025 Kepler release.",
    "The 8-hour livestream is Kepler's own event, described in a Kepler press release rather than fully independent press coverage; it is recorded as 'demonstrated' rather than 'shipped' or bare 'claimed' because it is a real, timestamped, continuous public demonstration.",
    "No named customer with invoice/serial-number/unboxing evidence was found, so delivery.status remains 'demonstrated', not 'shipped'.",
    "Shipped-bar research (2026-09-20): Web search for delivery evidence returned only NASA's unrelated Kepler/K2 space telescope mission and generic spec-sheet pages; no named-customer delivery evidence for the Kepler Robotics K2 humanoid was found in this pass. Remains at prior status."
