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.CollectExactlyOneRow collects single scalar value using RowTo
- pgx.CollectExactlyOneRow collects single struct matching db tags using RowToStructByName
- pgx.CollectExactlyOneRow collects single struct positionally using RowToStructByPos
- pgx.CollectExactlyOneRow collects single map using RowToMap
- pgx.CollectExactlyOneRow transforms single row with custom RowToFunc
- pgx.CollectExactlyOneRow returns pgx.ErrNoRows when result set has 0 rows
- pgx.CollectExactlyOneRow returns pgx.ErrTooManyRows when result set contains multiple rows
- pgx.CollectExactlyOneRow automatically closes rows upon completion, empty rows, too many rows, or scan errors
- pgx.CollectExactlyOneRow propagates underlying rows error
- sample helpers provide typed single-row scalar, struct, map, pointer, and custom collection utilities using pgx.CollectExactlyOneRow
