Abstract Originality Statement: The core theoretical framework of this study is completely constructed based on the original axiom system of the MFY three-variable steady-state hypothesis. The core variable definitions, closed-loop rules, and conduction paths are fully aligned with the first paper of the series, without any conceptual drift or logical modification. This paper is first published as a preprint for confirmation of rights. Objective: Following the unidirectional expectation-driven logic of the fourth paper in the MFY series, The Essential Definition of Sacrifice, this paper extends to the dual-subject interaction scenario, constructs a theoretical framework that can uniformly explain trust phenomena at all levels and in all scenarios, solves the core paradoxes that traditional trust theories cannot cover, such as "seeing clearly but not trusting", "believing firmly without seeing clearly", and "greater harm from betrayal by close people", and completes the theoretical leap of the MFY system from individual endogenous steady state to dual-subject interaction steady state. Methods: Strictly following the core axioms of "Ontological Anchor First, Operational Expectation First" and the irreversible conduction logic of Y→F→M of the MFY system, based on the Six-Anchor Five-Transformation Unified Model, this paper uses the reverse deduction method and case verification method to clarify the essential definition, core boundaries, and full-cycle dynamic evolution law of trust, and constructs the M-F-Y-F-M Bidirectional Spiral Framework of trust. Results: This paper attempts to clarify an unambiguous and verifiable essential definition of trust: Trust is a cumulative process of behavior in which a subject, knowing that there is an eternal error in the cognition of the interactive object, still actively transfers the control of its own interests and takes risks driven by its own positive expectation Y. This paper clarifies the four core elements and three core boundaries of trust, constructs a positive spiral ascending model for trust construction and a negative spiral attenuation model for trust collapse, fully covers the full-cycle dynamic process of trust from germination, ascending, steady state to rupture and repair, and attempts to cover... full-scenario explanations with a single conduction chain. The matching of each scenario remains to be independently empirically tested in the future. Conclusions: This paper completes a complete theoretical chain from the ontological basis of dual-subject communication (Six-Anchor Five-Transformation Unified Model), to the essential definition and full-cycle evolution law of trust (M-F-Y-F-M Bidirectional Spiral Framework), and then to the practical paths of brand management, crisis management, and anti-fraud intervention. It provides a testable starting point for the long-standing conceptual confusion of trust, attempts to fill the core research gaps of traditional trust theories, expands the applicable boundary of the MFY three-variable steady-state hypothesis in the field of social sciences, and provides an original and operable middle-level theoretical framework for relevant academic research and industrial practice. Keywords Trust; Emergence; Trust Repair; Brand Trust; Expectation-Driven; Fraud Intervention; Cognitive Filter; MFY Three-Variable Steady-State Model Core Contribution Statement The core contributions of this paper can be summarized into three points: First, it proposes a four-element essential definition of trust, and for the first time proves through the reverse deduction method of language usage habits that "positive expectation Y" and "active risk-taking" are two indispensable semantic cores of trust, and clarifies the essential boundaries between trust and understanding, coercion, and gambling. Second, it constructs the Six-Anchor Five-Transformation Unified Model, which proves the eternity and irreversibility of cognitive errors in dual-subject interaction from the ontological level, and provides a strict logical basis for the necessity of the existence of trust. Third, it proposes the M-F-Y-F-M Bidirectional Spiral Framework, which covers the full-cycle evolution law of trust from germination, ascending, steady state to rupture and repair with a single conduction chain, and derives 7 directly testable core hypotheses (including 1 complete experimental design draft), realizing a unified explanation of all scenarios from instrumental transactions to fraud brainwashing.

The core framework of the MFY hypothesis originates from an extreme case of psychological system collapse and self-healing that lasted for 12 months without external professional intervention. The complete definition, derivation rules, and first-principle construction process of the M-F-Y-F-M spiral ascending core model are detailed in the first paper of the series 1. The systematic test of the cross-domain applicability of the MFY hypothesis is detailed in the second paper of the series 2, the clinical cross-validation in the field of chronic insomnia is detailed in the third paper of the series 3, the systematic explanation of the essential definition of sacrifice and the unidirectional expectation-driven logic is detailed in the fourth paper of the series 4, and the cross-species verification of mammalian behavior is detailed in the fifth paper of the series 5. The core positioning of this paper is: Under the overall framework of the M-F-Y-F-M spiral ascending core model, to test its matching and explanatory power in the dual-subject interaction and group system level, complete the theoretical leap of the MFY system from individual endogenous steady state to dual-subject interaction steady state, and further verify the cross-domain universality of the MFY hypothesis.
