Contrato
- assert generated __eq__ does direct attribute comparison, so an instance containing NaN is not equal to itself even though Python tuple comparison shortcuts on identity
- assert attrs.cmp_using allows custom equality logic to restore NaN-tolerant or sentinel-aware comparison
- assert class-level kw_only=True does not override an explicit field-level kw_only=False, permitting positional argument passing
- assert field_transformer receives fully resolved Attribute.alias strings and Attribute.alias_is_default flags before transformer execution
- assert attrs.fields directly accepts an instance as well as a class
- assert attrs.Converter with takes_self receives preceding fields during __init__ but only sees subsequent fields during post-init assignment
- assert __attrs_pre_init__ receives the actual positional arguments passed to __init__ rather than their default values
