  "notes": "Read the SEC exhibit: MicroStrategy's August 11, 2020 press release reports purchase of 21,454 bitcoins and says Bitcoin was made the principal holding in its treasury reserve strategy. Thus the first treasury purchase occurred in 2020. The panel recipe is appropriate because the brief explicitly defines this as an off-chain historical fact; the copied chain-1 block window is a timestamp guard only."
