Full bilingual text and framework available at self-as-an-end.net The Born rule — that the probability of a measurement outcome is given by the modulus squared of the quantum state — is introduced as a postulate in standard quantum mechanics and confirmed by experiment to very high precision, yet the origin of its modulus-squared form has long been a central question in the foundations of quantum mechanics. The major approaches locate this origin in the mathematical uniqueness of Hilbert space (Gleason), the decision-theoretic norms of a rational agent (Deutsch–Wallace), the symmetry of system–environment entanglement (Zurek's envariance), subjective belief (QBism), or hidden variables (Bohmian mechanics). This paper gives an ontological origin for the modulus-squared readout within the Self-as-an-End (SAE) framework. The central claim: the modulus squared is the one-sided reading of a pre-closure state that lies below the causal slot, takes the uncertainty-wave form, and is simultaneously subject to time arrows on both sides — and is therefore without causality. In this region the time arrow and causality are distinct: the time arrow exists at every scale (the quantum evolves forward in our frame, the dynamical layer), whereas causality is the influence of a single-direction time arrow. Above the causal slot the state is subject only to single-direction influence, so causality holds and the outcome is definite; below the causal slot it is subject simultaneously to the our-frame and opposite-frame bidirectional time arrows (two faces of one dual-4DD structure, per Cosmo V), so no single direction can fix causation and there is no causality. A one-sided reading therefore cannot read off pre-written definite content, and presents as a probability distribution (degenerating to a definite P=1 readout for an eigenstate). At the amplitude layer this manifests as the conjugate pairing of dual orientations, ψ♯ψ = A² — the modulus squared. The paper works at three commitment levels: T1 (Gleason-type mathematical uniqueness, taken over externally), T2 (a strong structural derivation of the quadratic readout, the core contribution — not a full Gleason-equivalent theorem), and T3 (an ontological mechanism picture, offered as a candidate). It answers why the both-sided reading is multiplicative rather than additive: reciprocity prescribes that one side close with its dual in the native algebra of the object read — a scalar density closes additively (Λ₁+Λ₂=0), a complex phase carrier multiplicatively (ψ♯ψ=A²); the two substrates are isomorphic (both θ+θ♯=0), the microscopic one wearing one coat of exponential dualization. On this basis it places Born randomness (no pre-written content; weights from dual-orientation pairing), demarcates SAE from Gleason, Many-Worlds (via a causality firewall), QBism, and Bohmian mechanics, and interfaces with P4's cross-ladder readout, P5's Tsirelson bound, and no-signaling marginals. Whether the Born rule is modified in the strong-field regime is marked as an open problem. 玻恩规则——测量结果的概率由量子态的模平方给出——在标准量子力学中作为公设引入,由实验以极高精度确认,但其模平方形式的来源长期是量子力学基础的核心议题。主流进路分别把这一来源放在 Hilbert 空间的数学唯一性(Gleason)、理性主体的决策规范(Deutsch–Wallace)、系统-环境纠缠的对称性(Zurek 的 envariance)、主观信念(QBism)或隐变量(Bohmian)之上。 本文在 SAE(Self-as-an-End)框架内,为模平方这一读出形式给出一个本体来源。核心论点是:模平方是因果槽以下、测不准波形态、同时受双侧时间箭头影响、因而无因果律的闭合前态的单侧读数。在此区域,时间箭头与因果律是两件不同的事:时间箭头在任何尺度都存在(量子在本侧沿时间箭头正常向前演化,动力学层),而因果律的本体内容是单向时间箭头的影响。因果槽以上只受本侧单向影响,故有因果律、呈现确定;因果槽以下同时受 our frame 与 opposite frame 双向时间箭头影响(二者同为同一 dual-4DD 结构的两面,Cosmo V 既立),无单一方向可定因果,故无因果律。正因量子同时受双侧影响、无因果律可定向,单侧读出读不到预先写就的确定局部内容,而呈现为概率分布(若已是某测量的本征态,则退化为 P=1 的确定读出)。在振幅层,这表现为对偶取向的共轭配对 ψ♯ψ = A²,即模平方。 本文区分三层强度:T1(Gleason 类数学唯一性,外部承接)、T2(二次型读出的强结构推导,核心交付——非 Gleason 等价完整定理)、T3(本体机制图像,作为候选)。本文回答了为何双侧读出取乘性而非加性:互易规定一侧须与其对偶在被读对象的原生代数中闭合——标量密度加性闭合(Λ₁+Λ₂=0),复相位载体乘性闭合(ψ♯ψ=A²);两层底座同型(皆 θ+θ♯=0),微观层只多一层指数对偶化。据此本文给出玻恩随机性的定位(无预写内容,权重由对偶取向配对给出),划定 SAE 与 Gleason、Many-Worlds(以因果律防火墙)、QBism、Bohmian 的关系,并接合 P4 跨阶梯读出、P5 Tsirelson 上界与无信号边缘分布。强场下玻恩规则是否有修正,标记为开放问题。 Related identifiers (Related/alternate identifiers) All "is referenced by / references" relations to established SAE works.
