Empirical Audit of Structural Inevitability - A 14-Point Cross-Domain Constraint Ledger Supporting the Admissibility Inequality
2026-05-08
This paper presents a 14-point empirical and computational audit intended to be read as a constraint ledger. Each point is anchored to a named external source and extracted into a shared audit schema: hard boundary, discrete admissible basins or paths, and forced reconfiguration when a boundary is exceeded. The unification claim is that these repeated properties are consistent with a regime-specific budget boundary expressed as the Admissibility Inequality \(C_{\mathrm{tot}} \le B\), where \(C_{\mathrm{tot}} = (L_{\mathrm{eff}}/c)\cdot \kappa(\delta,f)\). All mappings are falsifiable by demonstrating stable continuation beyond the claimed boundary in the cited regime.

Scope and audit method
This document is an audit ledger. The target is not explanatory breadth. The target is checkability. Each audit point is written so a reader can identify: (i) what an external source demonstrates in its own domain language, (ii) the boundary or discreteness property extracted from that result, (iii) the mapping of that property to a budget boundary \(B\) and a cost measure \(C_{\mathrm{tot}}\), (iv) a replication handle describing what to measure or compute.
Governing constraint
Definition 1 (Admissibility Inequality). A configuration is admissible in a regime if it satisfies \[C_{\mathrm{tot}} \le B, \qquad C_{\mathrm{tot}} = \left(\frac{L_{\mathrm{eff}}}{c}\right)\cdot \kappa(\delta,f),\] where \(B\) is a regime-specific admissibility budget and \(\kappa(\delta,f)\) is the regime coupling or friction functional.
Remark 1. This paper does not assume a single closed-form expression for \(\kappa(\delta,f)\) across all regimes. The audit claim is structural: independent regimes exhibit boundary-gated persistence consistent with a budget form.
Audit point schema
Definition 2 (Audit point). An audit point is a regime where an external source exhibits: (1) a hard boundary condition, (2) discrete admissible basins or admissible path families, (3) forced reconfiguration when the boundary is exceeded.
The 14 audit points
Audit point 1 - Thermodynamic quantization floor in DNA stacking energies
Source: Banerjee et al. (2023) - DNA stacking
energetics dataset as cited in the PFT audit material.
External result: reported stacking free energies
cluster into discrete increments.
Audit observation: the regime does not present a
continuum of stable stacking energies.
Constraint mapping: a minimum stabilization increment
defines an effective floor - a budget boundary \(B\) for admissible microstates.
Replication handle: re-bin \(\Delta G\) values and compare quantized
clustering models to continuous null models.
Audit point 2 - Hexanucleotide context window as a constraint kernel
Source: Balaceanu et al. (2019).
External result: helical properties depend on a finite
context window rather than pair-local parameters.
Audit observation: admissibility depends on an extended
kernel - \(L_{\mathrm{eff}}\) is not
local.
Constraint mapping: budget evaluation is windowed -
stability is a finite-support constraint.
Replication handle: compare predictive error between
dinucleotide and windowed context models.
Audit point 3 - Discrete basins for twist and shift
Source: Balaceanu et al. (2019).
External result: structural parameters occupy discrete
basins (as summarized in the PFT audit material).
Audit observation: intermediate values are suppressed -
states cluster.
Constraint mapping: basin quantization is consistent
with admissibility classes delimited by \(B\).
Replication handle: fit mixture models and test
discreteness using model selection.
Audit point 4 - Topological lock in RNA G-quadruplex architecture
Source: Stafflinger et al. (2025).
External result: ligand recognition requires a specific
multi-strand topology.
Audit observation: partial or mis-phased assemblies are
not stable binding states.
Constraint mapping: topology defines an admissible
class - closure is a constraint satisfaction event.
Replication handle: perturb topology and measure loss
of binding or destabilization.
Audit point 5 - Approximation bound in protein folding on hexagonal lattices
Source: Shaw et al. (2014).
External result: proven approximation bounds for energy
minimization on hexagonal lattices.
Audit observation: there is a formal best-possible
bound for that regime.
Constraint mapping: a formal bound functions as a
regime budget limit for admissible optimization paths.
Replication handle: reproduce the algorithm and verify
the approximation guarantee.
Audit point 6 - Two-path constraint in B-to-Z inversion kinetics
Source: Chakraborty and Wales (2025).
External result: kinetic transition network resolves
into a small set of dominant mechanisms.
Audit observation: admissible transitions form discrete
path families.
Constraint mapping: path families are admissible sets -
excluded paths correspond to budget violation.
Replication handle: reproduce the transition network
and enumerate dominant path families.
Audit point 7 - Free-energy boundary cliffs under SinkMeta
Source: Pan et al. (2025).
External result: constrained exploration yields
effective boundary cliffs in the explored landscape.
Audit observation: exploration is bounded -
continuation terminates at the cliff.
Constraint mapping: cliffs represent budget boundaries
in a control-variable regime.
Replication handle: implement SinkMeta and verify
boundary cliff formation.
Audit points 8 and 9 - Chandrasekhar limit as global budget failure
Source: Chandrasekhar (1935).
External result: there exists a maximum mass for stable
degenerate configurations.
Audit observation: beyond the boundary, collapse occurs
- stability cannot continue.
Constraint mapping: \(B\) is a global budget - once exceeded,
forced resolution occurs.
Replication handle: reproduce the limit derivation
under the stated EOS assumptions.
Audit point 10 - Planetary maintenance budget placeholder
Source: a specific observational citation is
required.
External result: the PFT audit material asserts a
threshold claim for Saturn jet maintenance.
Audit observation: this point is structurally valid as
a budget form, but not audit-grade until a public source is
locked.
Constraint mapping: if verified, it is a
regime-specific \(B\) required for
persistence.
Replication handle: cite dataset or paper, verify
measurement, publish mapping procedure.
Audit points 11-14 - Spectral closure target and Riemann correspondence mapping
Source class: operator-spectrum approaches in the
Hilbert-Pólya program.
External result: the program motivates correspondence
between zeta zeros and spectra of suitable operators.
Audit observation: PFT states a target equivalence
between an AOL-defined operator and the zeta zero set.
Constraint mapping: spectral closure is treated as a
global admissibility criterion.
Replication handle: publish \(H_{\mathrm{AOL},E8}\) explicitly, compute
its spectrum, compare to the target set.
Unification result
Across the cited regimes, the extracted properties repeat: boundary-gated persistence, discrete admissible sets, forced reconfiguration beyond boundary. The audit-level conclusion is a cross-domain consistency statement supporting the budget form \(C_{\mathrm{tot}}\le B\).
