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.RowToAddrOfStructByPos maps row columns to struct fields positionally in declaration order and returns a pointer to the struct
- pgx.RowToAddrOfStructByPos ignores unexported struct fields when mapping column positions
- pgx.RowToAddrOfStructByPos handles nullable pointer fields and assigns nil when column value is null
- pgx.RowToAddrOfStructByPos returns an error when column count does not match exported struct field count
- pgx.CollectRows with RowToAddrOfStructByPos collects multiple rows into struct pointer slices and closes rows upon completion
- pgx.CollectOneRow and pgx.CollectExactlyOneRow work with RowToAddrOfStructByPos and return ErrNoRows and ErrTooManyRows as expected
- sample helpers CollectAddrOfStructsByPos, CollectOneAddrOfStructByPos, and CollectExactlyOneAddrOfStructByPos provide typed struct pointer collection
