Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

Contract
- pgx.CopyFromRows returns CopyFromSource implementing row-by-row iteration over 2D slice
- pgx.CopyFromSource.Next advances to next row and returns false when exhausted
- pgx.CopyFromSource.Values returns current row slice of values
- pgx.CopyFromSource.Err returns nil on clean iteration completion
- pgx.CopyFromRows handles empty row slice by immediately returning false on Next
- sample helpers validate row column widths, collect source values, and count rows
