O que costuma-se supor
sigs.k8s.io/yaml.Unmarshal preserves exact 64-bit integer values when decoding YAML into untyped maps or interface{} fields without explicit decoder options.
O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.
Contrato
- assert default Unmarshal silently truncates integers above 2^53 into float64 whereas JSONOpt UseNumber preserves exact int64 values as json.Number
- assert types implementing yaml.Unmarshaler are ignored while json.Unmarshaler and encoding.TextUnmarshaler are executed
- assert YAML numbers and booleans are coerced to strings when target struct fields are string type
- assert unmarshaling into map[interface{}]interface{} fails with JSON unmarshal error unlike standard YAML decoders
