This paper extends The Janus Path: A Structured Cognitive Model by introducing the origin-observation layer as a pre-structural supplement to JanusPath. It clarifies the meaning of structure in JanusPath and argues that structure is neither a purely objective entity nor a subjective projection, but a relational organization, distribution of tensions, and set of boundary conditions rendered between real constraints and observation modes. The paper proposes a dynamic generative chain from undifferentiated generativity (Dao), through situational tendency field (shi), concern, formed mind, observation mode, structure rendering, structural reflection, intervention, and reconfigured tendency field. Drawing on Daoist resources concerning language, non-attachment, contemplative observation, formed mind, and non-coercive action, the paper develops JanusPath from structural reflection toward origin-observation reflection while preserving it as a non-dogmatic cognitive methodology.
