The Born Rule from Counting

The Geometric Block Universe is a single completed geometric structure - a compact curved space carrying fields - in which every history compatible with the laws is present, together with the records that observers hold within it. Nothing in the block evolves. What an observer calls time is a relational ordering of records by internal coordinates, with a geometric direction, the logarithm of total volume, serving as the clock; where that clock stalls, a second clock built from accumulated volume carries the ordering through. Records are stable, mutually exclusive cells of a finite record space, the harmonics of low degree on a three-sphere, and an observer is a body that writes and reads such records. Three things that ordinary quantum mechanics must postulate are absent from this picture. There is no collapse: a measurement selects nothing, because every compatible outcome is already realised and a definite result is definite only relative to the observer's own record. There is no splitting of universes: the histories are labelled components of one structure, the number of them is not a primitive quantity, and nothing multiplies when a record is written. And there is no fundamental probability: the block contains only counts of qualified observer occurrences, and what an observer experiences as chance is self-location - the fraction of its own occurrences that carry a given record. Probability is an emergent appearance, not an ingredient. This paper shows that the quantum weights follow from counting. An earlier rigidity theorem of the programme showed that a positive linear incidence functional invariant under full-carrier heat resolution is proportional to volume, so that normalised incidence equals an inherited geometric density; the Born form of that density was an input, and this paper removes it. Three statements about counting- that the count of occurrences in a set of record points is the integral of a density depending on the amplitude at the point, that one attempt counts one, and that a non-interacting reader's counts cannot depend on a distant preparation, force the density to be the squared amplitude, with presence, unit counting, affinity and Born proportions for every sharp reader as consequences rather than assumptions. The Born weight is the conserved charge of the phase symmetry of each record, exact for the recorder the theory already contains, and its push-forward over states is the uniform reference distribution that earlier readers haad to be given by hand. The affine structure that makes counts quadratic is not free either: it is the positive first-order structure of the clock direction, derived for a clock that is a symmetry, and it survives the de Sitter trajectory the geometry selects with a bounce mixing 1/sinh²(πν) that is the same for every record mode. The recorder is realised on the canonical records of the five-rung carrier as a complete observer: it writes exactly distinguishable records at discrete pointer displacements, samples its pointer at the rate set by the evaluation overlap spectrum, and returns the branch weight with no threshold, no reference population and no preparation law; where the two records are not exactly distinguishable, the deviation from Born proportions is bounded and second order in their overlap. What remains assumed is stated once: that counting is local on the record manifold, that an attempt counts one, the selection of the record space, the standing of the recorder, and the identification of occurrence fraction with first-person credence. An unconditional derivation is not claimed. One consequence differs from quantum mechanics with continuous pointers and is recorded as a candidate signature: a recorded two-branch superposition decoheres, as a function of the write duration, with exact nulls, a partial revival of 21/91 at half the pointer period, full recurrence when the fibre closes, and a residual average coherence of 9/91.
