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