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
- pgtype.Array scans 1D text array literals preserving elements and dimensions
- pgtype.Array.SetDimensions configures multidimensional bounds and resizes internal elements
- pgtype.FlatArray scans 1D array literals into flat Go slices implementing ArrayGetter and ArraySetter
- pgtype.Array and pgtype.FlatArray Index, IndexType, and ScanIndex access elements and element types
- pgtype.Map encodes and decodes multidimensional pgtype.Array across binary wire format
- pgtype.Array scans nil source into invalid array representing SQL NULL
- pgtype.Array returns an error when scanning malformed array literals or invalid element formats
- pgtype.Map encodes pgtype.Array into PostgreSQL formatted text array literal
- Sample helper functions parse string arrays, flat int64 arrays, construct 2D arrays, and encode binary formats
