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
- pgconn.NewCommandTag parses query execution tags and identifies INSERT, UPDATE, DELETE, and SELECT commands
- pgconn.CommandTag.RowsAffected extracts affected row counts from command tags and returns 0 for non-row-modifying commands
- pgconn.PgError formats server errors with severity, message, and SQLSTATE code and provides structured error field access
- pgconn.SafeToRetry evaluates whether an error occurred before sending data to the server
- pgtype.Multirange[T] decodes PostgreSQL multirange text representations into slices of typed ranges
- pgtype.Multirange[T] handles empty multirange representations and null values
- pgtype.MultirangeCodec encodes generic multiranges back into PostgreSQL text format
- pgtype.EnumCodec decodes and caches repeated enum strings in memory and encodes string enum values
- pgtype.InetCodec parses IPv4 and IPv6 network addresses and CIDR prefixes into netip.Prefix and netip.Addr
