A quantum phase reference is part of the state from which an observation record emerges. Within the physical-observation dual-axis structure, we describe such a reference by a compact quantum coordinate coupled to a finite-dimensional physical system. A covariant rotor action gives the joint evolution and expresses the readout's phase acceleration through ordered correlations and a covariant force. In a qubit model whose dynamics preserve two adjacent observation momenta, the first harmonic depends on four complex correlations. For fixed nondegenerate parameters, its full complex history requires eight real state variables. For phase increments alone, a common amplitude and phase factor can be removed, leaving three complex correlation ratios. We prove that these six real variables are locally minimal at generic states for every fixed nondegenerate parameter choice. Six suitably timed phase estimates and an initial reference recover the ratios by solving real linear equations; an error bound relates uncertainty in those estimates to the subsequent phase prediction. The role of the retained correlations is illustrated by preparations with equal marginals and equal initial phase, rate, and acceleration, but different future phases. We also describe how the state continues through a zero of the first harmonic and how finite integration windows affect the available information. The resulting theory connects a joint quantum action to phase prediction from finite records, subject to independent physical characterization of the phase inertia and coupling.

Coherence lifetimes reflect both the evolution of a quantum system and the conditions under which its state is reconstructed. We study these contributions in Physical--Observation Dual-Axis (PODA) dynamics. For a coherent-state superposition in a passive thermal cavity, we derive the interference envelope and obtain initial-rate lifetimes of 19.73 and 28.89 ms from published apparatus parameters. These values agree with the scale of the reported decay, although the envelope lifetime and the time extracted from a tomographic fit need not coincide. The observation coordinate is then allowed to evolve under the same coherent action. Projection onto an isolated cavity mode determines the frequency response and its reciprocal optical force; propagation of the initial covariance gives the relative-phase variance, including the readout reference. For coupled quadratic motion with a classical canonical preparation and a fixed readout reference, a fluctuation--response identity determines the phase-coherence curve from the reciprocal susceptibility and preparation energy. A finite set of stable modes gives recurrent or quasiperiodic coherence. A second relation predicts the ratio of two coherence curves when only the initial observation covariance changes. The common thermal attenuation cancels from this ratio, while the induced physical response remains. Together, these relations connect coherence to response and preparation measurements without introducing a fitted phase-decay rate.
Phase transport specifies the change of phase along a path, but a predictor must also determine the path from initial data. We study this distinction in a conservative projector–connection model on the physical--observation dual-axis structure. A homogeneous two-mode reduction preserves the field equations, Gauss constraint, and energy, and has a global classical flow. Horizontal transport followed by a fixed analyzer gives a nonvanishing coherent readout on an invariant plane. With known parameters, no active input, and zero Gauss momentum, we derive a closed system of seven inner products for the planar branch. The Jacobian of the phase rate and its first six time derivatives has full rank at an explicit rational state, proving that seven is the minimal smooth predictive dimension on an open dense set. The initial phase is independent of these seven states. Near equilibrium, the linear observable motion reduces to two states; on a separate invariant family, internal motion leaves the phase constant. These results are placed in a protocol-dependent realization theory based on future phase increments. We also derive a background-dependent frequency law and the leading nonlinear phase coefficient. Signed perturbations and half-amplitude contrasts isolate the cubic contribution, while an explicit correction separates it from the cubic term introduced by coherent integration. Dynamic references and finite-window array processing illustrate the distinction between instantaneous alignment and phase prediction. All numerical examples are synthetic; the proposed physical tests require independent calibration of a device realizing the stated action and readout.
When the conditions under which a record is formed remain fixed, a physical theory may represent that record completely by a unary law of the state observed. This paper asks what structure is forced when the same independently certified physical identity gives different complete records under different formation conditions. The initial datum distinguishes two typed empirical roles, while the state identity of the formation side is derived from its complete behavior. Failure of factorization through the first projection proves that the formation-side role cannot be deleted. The complete row and column behaviors of the primitive law then determine two kernel pairs and their coequalizers. Unique descent retains every observable distinction while removing every redundant label, and the resulting realization is terminal among all exact role-preserving realizations. The product pairs the reduced roles; a pullback extracts the combinations on which records can actually be formed. Only after these steps does exponential transposition identify each surviving formation class with one complete response map. The resulting bijection supplies the state criterion and establishes the observation-state object. Compatibility with the antecedent theory preserves the independently given physical state space and yields the physical–observation law in which a fact is generated jointly by the state observed and the state of observation. The same construction gives exact criteria for conditional, label-free, and joint identifiability and selects the same-source pullback on which transport may subsequently be defined. A nonzero coherent response on that pullback yields the phase-transport fundamental equation, the first fundamental equation written directly on observation space. Quantum theory subsequently enriches this canonical interface. Coherent response and full circular phase select the complex field; reversible binary mixing yields CP1 ∼= S2 ; independent composition creates the four-dimensional event domain; response-event identity glues probabilities across complete contexts; and Gleason representation with marginal consistency gives the Born trace pairing. The two-qubit correlation tensor then yields the singlet cosine law, the CHSH inequality, the Tsirelson bound, and the Horodecki spectral criterion. Bell violation is thereby identified with the absence of a positive global answer section across incompatible observation states. The quantum formalism is thereby closed into one architecture: complex state geometry describes coherent physical possibility, complete observation states specify the ways in which facts may form, the Born interface joins them, and quantum instruments carry a realized fact into subsequent dynamics. Fixed observation sections recover classical unary laws, while smooth equivariant enrichment lifts relativistic frame geometry and internal gauge geometry to the same joint domain. The central result is ontological. Physobser Theory admits observation into objective physical reality not as a mind, an external readout, or a perturbation, but as an irreducible state-bearing axis; a fact is generated at its lawful interface with physical state. Category theory is the proof instrument. The discovered physical content is the dual-axis constitution of facts, which supplies a common foundation for quantum, classical, relativistic, and gauge physics.
Classical theories typically model a complete record as a unary function of a physical state, treating observation conditions as external parameters. However, quantum mechanics exhibits a fundamental tension: the same independently certified physical input can yield different complete records when observation conditions vary, giving rise to the century-old measurement problem and the EPR paradox. In this work, we derive the necessary state architecture to resolve this without conflating the physical input with the conditions through which its record is formed. By applying behavioral equivalence and redundancy elimination within the category of sets, we prove that the formation-side difference cannot be mathematically removed. This forces the “observation state” to emerge as an irreducible, objective, state-bearing axis, establishing a strict physical–observation dual-axis (PODA) architecture. We emphasize that this dual-axis structure represents two non-interchangeable projection responsibilities, rather than orthogonal coordinates or dynamically decoupled systems. Under stated coherence and composition conditions, this dual-axis geometry naturally yields the complex field, binary projective geometry, and the Born trace pairing. Crucially, it further derives the Schrödinger equation as a covariant temporal composition, the CHSH inequality, and the attainable Tsirelson bound. In standard quantum mechanics, the complex field, the Schrödinger equation, and the Born rule are independent axioms. In our framework, they are unified as geometric corollaries of the PODA structure. Within this framework, the notorious quantum paradoxes are naturally dissolved: “wave-function collapse” is revealed as a conditional transition at the observation interface, and “decoherence” is understood as the objective geometric coupling between the physical and observation axes, rather than random environmental noise. Bell violation is thereby identified not as superluminal influence, but as the absence of a positive global answer section across incompatible observation states. Finally, the theory proposes a specific table-top experiment that predicts a sharp, parameter-free numerical constant: a geometric phase of 0.7π ≈ 2.1991 radians. This value directly distinguishes the dualaxis mechanism from standard quantum mechanics, which predicts exactly zero for the same configuration. Observing this constant would confirm the physical reality of the observation axis, whereas a null result falsifies the mechanism.

For finite-dimensional binary systems and their bipartite composites, this paper establishes a conditional representation chain from a physical–observation dual-axis structure to quantum Bell correlations. An observational fact is jointly generated by a complete physical state and a complete observation state. Additivity and associativity of coherent responses, two-sided cancellation, and a full circle group of scalar phase transport select C among finite-dimensional unital associative real response algebras. Reversible mixing then determines a Hermitian metric up to an overall positive factor. Normalized two-channel responses form S3, and quotienting by their common phase yields the rank-one observation-event space and, with an outcome label, the pure observation fiber S3/U(1)=CP1≃S2. The universal bilinear composite of two independent systems is C4. Probabilities are first assigned within complete measurement contexts. Events with the same response filter are operationally interchangeable, so the local assignments glue along the observation axis into a positive orthogonally additive measure on the full projection lattice. Gleason's theorem then gives the unique trace representation p(P∣x)=Tr(ρxP), while composite marginal consistency returns the trace pairing to each local binary fiber. Every two-qubit correlation therefore has the universal form Eρ(a,b)=aTTρb. Joint rotational invariance and perfect equal-axis anticorrelation uniquely fix Tρ=−I3, producing the singlet cosine law E=−a⋅b=−cosθ. Finally, the local commutators in the squared CHSH operator confine all realizable correlations to 22. Fine-measurement completeness supplies saturating directions, while sharp preparation and reversible covariance make the singlet accessible. Thus CP1, the Born pairing, the cosine correlation law, and the Tsirelson bound arise within one chain linking phase structure, independent composition, and cross-context probability consistency.
