SCHEDULE 13D




Comment for Type of Reporting Person:
Percent of class represented by amount in row (11) is calculated based upon 224,730,144 shares of common stock, $0.001 par value per share, outstanding as of November 4, 2025, as reported by the Issuer on the cover of its Form 10-Q for the quarterly period ended September 30, 2025 and filed with the U.S. Securities and Exchange Commission on November 6, 2025 (the "Form 10-Q").
