Context

These entries are not open-market purchases or sales; they reflect equity awards and an assumed option resulting from a corporate combination. Because they were granted/assumed at $0, they represent grant/conversion events rather than purchases that signal immediate personal investment. Derivative holdings (options) remain subject to vesting and exercise conditions.
