Proposed resolution: YES Actual value: 20.99 USD/kg
Rationale: The skeptic's objection about the 12-day gap is noted, but the interpretation ladder supports using the best available evidence when exact-date data is unavailable. The research shows consistent pricing above $18/kg across multiple sources and timeframes (May 19 spot at $20.99, USGS 2025 annual average at $22/kg), with no evidence of volatility or price drops near month-end. The absence of a named source in the criteria means any authoritative source is acceptable.
