Irreversible transitions appear across physics, cognition, morality, social systems, and artificial learning systems, yet no existing framework provides a unified structural account of why certain transitions cannot be reversed or how identity reorganizes after collapse. This paper introduces the Gate–River Framework, a domain‑general theory of irreversible transformation grounded in identity, information, and constraint. The framework proposes that all identity‑bearing systems operate within basins of stability governed by basin‑internal laws. When internal contradiction exceeds structural coherence, the system reaches a boundary at which the basin’s governing law can no longer sustain identity. This boundary—the Gate—acts as a non‑invertible transition operator that collapses the prior identity while preserving deeper informational invariants. Beyond the Gate lies a forbidden region in which the old identity cannot exist, followed by the River, the structural point of no return where reconstructability of the prior identity is lost. A new identity basin emerges only after reorganization under new constraints. The paper demonstrates that this architecture appears independently in General Relativity, quantum measurement, thermodynamic irreversibility, neural network catastrophic forgetting, human psychological transformation, moral collapse, ecological regime shifts, and social revolutions. The Gate–River Framework resolves the longstanding structural conflict between General Relativity and Quantum Mechanics by showing that each governs a different layer of identity: GR governs the continuity of physical identity (kernel), while QM governs the continuity of information (generative layer). Neither law is universal; both fail at boundaries. The Gate provides the missing operator that connects them. Drawing on a structured dataset of over 460 transformation cases, the paper shows that while the mechanism of irreversible transition is invariant, the form of post‑collapse reorganization is shaped by environmental variables such as feedback quality, symbolic density, and knowledge structure. The Gate–River Framework therefore offers a unified, cross‑domain account of irreversible transformation and establishes a structural foundation for understanding identity, collapse, and reorganization across physical, cognitive, and social systems.
