Systematic Pair-Level Campaign for δpair: Convergence, Inter-Pair Concentration, and Normalization Structure

The O-series defines a canonical pair-level capacity observable and establishes that vertical non-injectivity does not change its observable rank. The further prescription β*=1/(δₚₐᵢᵣ+12), however, imports the changing-degree LPS growth equation into a fixed-degree Heisenberg cascade and has no native carrier there. The value δₚₐᵢᵣ ≈ 7.44 extracted in O16 was based on a single conjugate pair per prime and a limited prime range. The present paper reports a systematic campaign computing δₚₐᵢᵣ across the $(q-1)/2$ conjugate pairs $(c, q-c)$, originally for q ∈ \29, 61, 101, 151, 211\ with $M = 50$ block samples per pair, and here extended to q ∈ \307, 401, 601\ by a capped breadth-first construction that reproduces the pair observable exactly at a fraction of the cost (with reduced sampling: $M = 16$ at $q = 307$, $M = 8$ at $q = 401, 601$). Three results are established. First, δₚₐᵢᵣ(q) is extracted reproducibly and concentrates across pairs, confirming that it is a stable fixed-q pair statistic rather than a block-level fluctuation. Second, and centrally, the extended campaign shows that the raw exponent δglobal(q) descends monotonically into the admissible window $[7.4, 10.6]$ on its own, reaching $7.61$ at $q = 601$, without any finite-size correction; the O14 normalization correction, needed to bring the small-q values into the window, becomes progressively unnecessary at large q and eventually overcorrects, sending the corrected quantity below the lower edge $7.4$. The admissible-window agreement is therefore carried by the raw observable, not by the corrected one. Third, the asymptotic value δ_∞ remains insufficiently constrained by the accessible range: competing convergence laws — notably $1/q$ and 1/√q — remain statistically viable, so no single extrapolated δ_∞ is claimed. For comparison only, applying the legacy reciprocal map β* = 1/(δₚₐᵢᵣ + 12) produces the narrow interval $0.108$–$0.123$ across q ∈ \211, , 601\. This is a phenomenological numerical coincidence, not a Heisenberg capacity-to-rate inference. Keywords.
