What to expect

• Check value_unit before comparing values. The SEC changed the unit: values were in thousands of dollars before 2023-01-03, and in dollars from that date. Each row says which.
• Amendments are separate rows. Every filing is kept, and an amendment never overwrites the original. Read amendment_type to tell a restatement from added holdings.
