The filings give report dates, not purchase dates. The earliest filing from Blackrock, Inc. on this page is the Schedule 13G/A, filed 2026-07-30, reporting 16%. That earliest filing is itself an amendment, which updates an earlier report.

Neither.

It is not an audit and not a full cap table: holders who never reached 5% are not listed, and a stake can change after its latest filing.
