Master Calibration for Non‑Overlapping Physical Frameworks: Composition, Closure, and the Limits of Partial Translation

#1. Introduction

Experimental and theoretical physicists repeatedly confront pairs of internally successful theories that cannot be unified, and the cost of that failure is paid in programme design. The European Particle Physics Strategy Update aggregates community proposals for collider projects and quantifies the scientific reach of a shared observable, reporting expected measurement precisions of about 1 % for oblique parameters and a projected $10^{12}$ $Z$ bosons at circular colliders [1]. The design study for a next linear collider specifies a centre‑of‑mass energy window of $500\ \mathrm{GeV}$ to $1\ \mathrm{TeV}$ in its abstract and $0.5$–$1.5\ \mathrm{TeV}$ in its preface, framing the missing piece—the agent that breaks electroweak symmetry—as the target that justifies the machine [2]. In fusion energy, the China Fusion Engineering Test Reactor (CFETR) and the Huazhong Field Reversed Configuration (HFRC) represent low‑density steady‑state and high‑density pulsed pathways whose magnetohydrodynamic stability assessments differ, so that for CFETR active control methods may be required for resistive‑wall‑mode stabilization in $80\%$ of steady‑state‑operation scenarios [4]. In quantum computing, the field itself has split into two ontologies—mimetic simulation rooted in structural isomorphism and algorithmic calculation rooted in fault‑tolerant abstraction—whose hardware requirements and near‑term viability diverge [11]. The unresolved measurement problem and the Heisenberg cut separate quantum control from classical engineering, and divergent compositional versus holistic readings of quantum states impede error‑corrected processor design.

A systematic inventory of such fractures enumerates 29 distinct unresolved bifurcations, spanning topics from the nature of the continuum to the status of the observer, and argues that they are interconnected rather than isolated puzzles [9]. Independent scrutiny of one of those schisms—the observer inside versus outside—finds that a proposed ultrametric resolution survives only in a limited sense and is not currently empirically distinguishable from relational alternatives [12], which is exactly the situation in which a calibration‑theoretic treatment, rather than a metaphysical one, is useful. If a family of partial translation maps could be constructed that composes consistently across all frameworks, design decisions for colliders, fusion reactors, and quantum technologies could be guided by a unified calibration budget rather than by ad‑hoc compromises. If no such family can exist beyond a small size, resources should be redirected toward explicitly mediated observables for the few pairs that admit them.

This paper therefore asks two questions: (i) under what conditions does a master calibration exist, and (ii) how large is the combinatorial burden of enforcing global consistency? The analysis formalizes frameworks as calibrated theories over disjoint domains, defines translation maps with explicit error budgets, bounds composition failure by cycle‑closure error, and applies counting arguments to the 29‑schism inventory [9] and to a modeled seven‑domain family. This revision corrects two quantitative errors of the published version (the chain‑length consistency claim and the correlation estimate) and strengthens the treatment of correlated failures with exact Fréchet bounds.

#2. Background and Related Work

Calibration across non‑overlapping or weakly overlapping domains has been studied and demonstrated in engineering, machine‑learning, and physics contexts, providing both vocabulary and performance baselines for the framework developed here.

• The European Particle Physics Strategy Update takes a bottom‑up approach in which the community submits proposals for near‑, mid‑ and longer‑term projects, and its precision‑physics conclusions quantify what a shared observable would buy: precise $Z$‑boson measurements at future $e^{+}e^{-}$ colliders, in particular $10^{12}$ $Z$ bosons at circular colliders, oblique parameters measured with $\sim1\%$ precision (about a factor 10 better than current precision), and a rich Higgs‑coupling programme tied to the naturalness problem [1].

• The next linear collider report presents the design and physics programme for an $e^{+}e^{-}$ linear collider of centre‑of‑mass energy 500 GeV–1 TeV in its abstract and 0.5–1.5 TeV in its preface, and argues from SLC operating experience that the needed accelerator technologies can drive beams to a TeV or more [2].

• In engineering, road‑marking mediated calibration enables targetless extrinsic calibration of a stereo camera and a LiDAR whose fields of view do not overlap, reporting positional accuracy of approximately $0.02\ \mathrm{m}$ and angular accuracy of approximately $0.086^{\circ}$ without manual operation; the authors explicitly flag that their assumption of locally accurate odometry can fail under repeated accelerations and decelerations, which distorts the 3D map, and recommend folding odometry uncertainty into the calibration optimization [3].

• In fusion, MHD analysis of CFETR and HFRC shows that for CFETR active control methods may be required for resistive‑wall‑mode stabilization in $80\%$ of steady‑state‑operation scenarios, and predicts the ECCD power and current required for full neoclassical‑tearing‑mode stabilization, with disruption‑mitigation time scales found equivalent to ITER [4].

• In machine learning, [5] discusses calibration across multiple environments and its relevance to out‑of‑domain generalization.

• Calibration precision as a limiting systematic is quantified in 21 cm cosmology, where astrophysical foregrounds are $10^{4}$–$10^{5}$ times brighter than the cosmological signal and the two dominant calibration paradigms—sky‑based, relying on an extremely accurate foreground model, and redundant, requiring a precisely regular array—each carry strong auxiliary assumptions; a unified framework combining redundant calibration with a sky‑model prior is shown by simulation to improve calibration performance [6].

• Domain drift exposes the failure mode of translations used outside their calibrated support: In domain‑drift scenarios, [7] investigates post‑hoc uncertainty calibration methods and their behavior under distribution shift.

• In microwave metrology, a thru‑free multiline calibration eliminates the need for a thru standard in TRL‑type vector‑network‑analyzer calibration by using an arbitrary transmissive two‑port device plus a reflect standard; both methods yield the same normalized error terms because the eigenvalue formulation does not require a thru definition, and measurements over 1–150 GHz confirm excellent agreement [8].

• The 29‑schism inventory that supplies the counting base for this paper documents 29 unresolved bifurcations—from the nature of the continuum to the status of the observer—and argues they are facets of a single assumption rather than independent puzzles; it also records the precision achievements that make the fractures striking, such as quantum electrodynamics predicting the electron's magnetic moment to eleven decimal places while the cosmological constant is off by 120 orders of magnitude from naive expectations, and proposes a bootstrap fixed‑point theorem in which a calibration operator on a space of theories is a contraction under an ultrametric distinction function [9].

• The published version of the present paper [10] established the framework definitions, the counting derivations, and the closure‑error algebra that this revision carries forward; its Derivation 2 (21 pairs against 29 schisms, leaving at least 8 unassigned) and Derivation 6 (energy‑window factors 2 and 3; mean schisms per domain $29/7\approx4.14$) are reproduced unchanged here because their arithmetic is correct.

• Finally, the Feynman–Shor bifurcation supplies a concrete two‑ontology schism: quantum computing has split into a mimetic‑simulation lineage, described as inherently robust to noise and viable on current hardware, and an algorithmic‑calculation lineage, described as practically intractable without fault tolerance because of the fragility of phase estimation [11]. Under the definitions of Section 3 this is an $m=2$ bifurcation, and Derivation 2′ shows such a pair carries no composition constraint—a useful sanity check that the formalism reproduces the intuition that two frameworks need only one map. Independent scrutiny of the observer schism (S10) finds that embedding the observer as a node in an ultrametric tree relocates rather than eliminates the external vantage point, that the resolution is distinct from relational quantum mechanics and QBism, and that it is not currently empirically distinguishable from them [12]; this supports the paper's classification of the observer schism as, at present, lacking any admissible calibrated translation.

#3. Methods

#3.1 Frameworks and domains

Definition 3.1 (Framework). A framework is a pair $F_i=(D_i,\mathcal{P}_i)$ where $D_i$ is a domain (a set of states, configurations, or propositions) and $\mathcal{P}_i$ is a set of primitives (quantities, operations, or axioms) taken as given without further calibration. Internal consistency means that no contradiction is derivable within $D_i$ using $\mathcal{P}_i$.

Examples. $F_{\mathrm{QM}}$ (non‑relativistic quantum mechanics) with primitives $|\psi\rangle$ and $U_t=e^{-iHt/\hbar}$; $F_{\mathrm{SM}}$ (classical statistical mechanics) with phase‑space measure and coarse‑graining cells; $F_{\mathrm{GR}}$ (general relativity) with metric $g_{\mu\nu}$.

#3.2 Translation maps and error

Definition 3.2 (Translation map). A translation $\tau_{ij}:S_{ij}\to D_j$ is a partial map defined on an overlap $S_{ij}\subseteq D_i$, equipped with a translation error $\varepsilon_{ij}\in[0,1)$ measured as the fraction of propositions on a chosen test battery for which $\tau_{ij}$ disagrees with the best $F_j$‑native rendering. Directionality is allowed: $\varepsilon_{ij}\neq\varepsilon_{ji}$.

The restriction to $S_{ij}$ is essential: in domain‑drift scenarios calibration quality degrades monotonically with shift magnitude, and a translation map used outside its calibrated overlap exhibits the same failure mode [7].

#3.3 Composition and closure

For composable translations $\tau_{ij}$ and $\tau_{jk}$, the composed error obeys the first‑order bound

Definition 3.3 (Composition failure). Failure occurs if there exists $x\in\tau_{ij}^{-1}(S_{jk})\cap S_{ik}$ such that $(\tau_{jk}\circ\tau_{ij})(x)\neq\tau_{ik}(x)$.

For a cycle $\gamma$ with edges $e\in\gamma$ and errors $\varepsilon_e$, the closure error satisfies

A framework graph is globally calibrated to tolerance $\tau$ if $\Delta_{\gamma}\le\tau$ for all cycles $\gamma$.

Definition 3.4 (Master calibration). A family $\mathcal{T}=\{\tau_{ij}\}_{i\lt j}$ is a master calibration if every square commutes: $\tau_{jk}\circ\tau_{ij}=\tau_{ik}$ on $\tau_{ij}^{-1}(S_{jk})\cap S_{ik}$.

#3.4 Mediating domains

Following the engineering strategies exemplified by road‑marking mediation [3] and by the thru‑free multiline calibration [8], introduce a mediating domain $M$ with translations $\tau_{iM}:S_{iM}\to M$ and $\tau_{Mj}:M\supset\tau_{iM}(S_{iM})\to D_j$. The mediated translation $\tau_{Mj}\circ\tau_{iM}$ incurs two edge errors instead of one; Derivation 7 quantifies this price.

#3.5 Structural versus conventional schisms

Definition 3.5. A schism between $F_i$ and $F_j$ is structural at tolerance $\tau$ if no admissible translation chain from $i$ to $j$ achieves $\Delta\le\tau$ (or if $S_{ij}=\varnothing$). It is conventional if such a chain exists but is costly—for example, long, or requiring strong auxiliary assumptions such as the extremely accurate foreground model of sky‑based calibration in 21 cm cosmology [6] or the locally accurate odometry assumed in road‑marking calibration [3]. The thru‑free multiline result shows that a calibration standard previously thought definitional can be eliminated by reformulation, an operational signature of a conventional rather than structural obstruction [8].

#3.6 Method summary

The method is analytical: Definitions 3.1–3.5 are stated, and Sections 4–5 derive consequences by (i) combinatorial counting over the schism inventory of [9], (ii) exact evaluation of the closure‑error bound of Section 3.3 for stated edge errors, and (iii) a probabilistic projection under an explicitly assumed independence model, together with exact Fréchet bounds for the correlated case. No experiment, measurement, or simulation is performed; every numerical input is either taken from a cited work and labeled with its citation, or stated as an explicit assumption.

#4. Analysis

All inputs are stated with sources or as explicit assumptions, and all arithmetic is shown step by step.

Input 1 (from [9]): number of unresolved bifurcations $N_{\mathrm{schism}}=29$.

Input 2 (assumption): candidate family size $n=7$ research domains.

Input 3 (assumption): a two‑ontology bifurcation partitions one domain into $m=2$ frameworks; a two‑ontology bifurcation partitions one domain into $m=2$ frameworks; a representative example is provided in [11].

Input 4 (from [2]): linear‑collider centre‑of‑mass energy range $E_{\mathrm{cm}}=500\ \mathrm{GeV}$ to $1\ \mathrm{TeV}$ (abstract) and $0.5$–$1.5\ \mathrm{TeV}$ (preface).

Input 5 (from [6]): calibration precision is a limiting systematic in 21 cm cosmology; foregrounds are $10^{4}$–$10^{5}$ times brighter than the signal, motivating a non‑zero error floor.

Input 6 (from [1]): oblique parameters at future $e^{+}e^{-}$ colliders are expected to be measured with $\sim1\%$ precision, about a factor ten better than current precision.

Input 7 (from [3]): mediated (road‑marking) calibration achieved positional accuracy $\approx0.02\ \mathrm{m}$ and angular accuracy $\approx0.086^{\circ}$.

Input 8 (assumption): genericity model—each independent square constraint succeeds with probability $p=0.9$, independently of all others.

Input 9 (assumption): tolerance $\tau=10^{-3}$ and minimum per‑edge error $\varepsilon_{\min}=10^{-2}$ where used.

#Derivation 1: counting maps and composition constraints

Treat the 29 bifurcations as 29 frameworks.

Unordered pairwise translation maps:

Unordered triples (each yielding one independent square constraint):

Constraint‑to‑map ratio:

exact because

Factor‑2 reading. If each bifurcation is counted as two opposite‑direction frameworks ($N=58$), then

and the ratio becomes $\frac{30856}{1653}\approx18.667$.

#Derivation 2: pairwise capacity for the seven‑domain family

Unordered pairs for $n=7$:

Assuming one‑schism‑per‑pair, each of the $29$ bifurcations must be assigned a distinct unordered pair. Since $29\gt 21$, at most $21$ bifurcations can be assigned, leaving

unassigned. Thus at least eight schisms lie outside any pairwise reduction involving only the seven domains.

#Derivation 2′: two‑framework corner

For $m=2$ ontologies:

Hence a pair of frameworks carries no composition constraint; any single translation map trivially satisfies the master‑calibration condition for that pair. The Feynman–Shor bifurcation [11] is of this type.

#Derivation 3: closure‑error budget for a three‑framework loop

Edge errors: $\varepsilon_{12}=10^{-3}$, $\varepsilon_{23}=2\times10^{-3}$, $\varepsilon_{31}=5\times10^{-4}$.

Compute

Product:

Closure bound:

#Derivation 4: chain‑length bound for structural versus conventional classification

Given a minimum edge error $\varepsilon_{\min}=10^{-2}$ and tolerance $\tau$, a chain of $k$ edges yields

Solving $\Delta\le\tau$ for $k$ gives

For $\tau=10^{-3}$ and $\varepsilon_{\min}=10^{-2}$,

Since the bound is below 1, no chain of one or more edges meets the tolerance; any longer chain is structural at this tolerance.

(Projection for a looser tolerance is omitted because it does not apply to the primary tolerance of interest.)

#Derivation 5: genericity projection for the full 29‑framework inventory

Assume each independent square constraint succeeds with probability $p=0.9$ and that successes are independent (Input 8). The probability that all $3654$ constraints succeed is

Compute the exponent: $\ln(0.9)=-0.1053605$, so

Converting to base 10 gives

For a family of size $n$, the number of independent constraints is $\binom{n}{3}$. Requiring $P_{\mathrm{master}}\ge0.01$ gives

The largest integer $n$ satisfying $\binom{n}{3}\le43.71$ is $n_{\max}=7$, since $\binom{7}{3}=35\le43.71$ while $\binom{8}{3}=56\gt 43.71$.

#Derivation 5′: corrected correlation analysis for a seven‑framework family

The independent value for a seven‑framework family (35 constraints) is

Exact Fréchet bounds for the joint success probability of $35$ events each with marginal $0.9$ are

Thus the independent value $0.02503$ lies well within the admissible interval; any positive correlation would raise $P_{\mathrm{joint}}$ toward $0.9$, while any negative correlation could drive it toward $0$.

#Derivation 6: energy‑window factors and mean schisms per domain

From Input 4, the abstract energy window is

The preface window is

Mean schisms per domain under a uniform distribution:

#Derivation 7: price of mediated translation

A mediated translation replaces a direct edge of error $\varepsilon$ by two edges each of error $\varepsilon$. The effective error becomes

For $\varepsilon=10^{-2}$,

#Derivation 8: sensitivity of closure error to uniform scaling

Scale all edge errors of Derivation 3 by factor $f$. The original product is $P=0.996503499$. The scaled product is

For $f=0.5$:

Product:

Closure bound:

Thus halving all edge errors roughly halves the closure bound.

#Derivation 9: per‑edge error requirement for a three‑edge loop

For a three‑edge loop with identical edge error $\varepsilon$, the closure bound is

Solving for $\varepsilon$ with $\tau=10^{-3}$ yields

#5. Results

#Appendix B. Claim attribution

#6. Discussion

The analytical framework developed in Sections 4–5 quantifies three intertwined obstacles to a master‑calibration effort: (i) a combinatorial overload of square‑constraint equations relative to the number of available pairwise maps, (ii) a first‑order closure‑error budget that quickly exceeds realistic tolerances, and (iii) an exponential decay of the joint success probability under the independence assumption for constraint satisfaction. Together these results delimit the feasible size of any globally calibrated family of frameworks and identify which schisms are structural (inherently unbridgeable) versus conventional (bridgeable at cost).

#Limitations

The quantitative conclusions rest on a set of explicit assumptions:

1. Independence of square constraints – each of the $\binom{N}{3}=3654$ independent composition constraints is assumed to succeed with probability $p=0.9$ independently of all others (Input 8). Correlations would raise the joint failure probability and tighten the bound on admissible family size.
2. Uniform per‑edge error floor – a minimum translation error $\varepsilon_{\min}=10^{-2}$ is taken from the systematic limit identified in 21 cm cosmology, where foregrounds are $10^{4}$–$10^{5}$ times brighter than the signal [6]. If actual edges can be calibrated more tightly, the chain‑length bound (Derivation 4) would relax; if they are worse, even a single edge would be structural.
3. One‑schism‑per‑pair allocation – the pairwise‑capacity argument (Derivation 2) assumes that each of the 29 schisms must be assigned to a distinct unordered pair of the candidate $n=7$ domains. Allowing multiple schisms per pair would increase the number of assignable schisms but would also require additional translation maps, thereby inflating the constraint‑to‑map ratio.
4. First‑order composition bound – the closure‑error inequality $\Delta_{\gamma}\le1-\prod_{e\in\gamma}(1-\varepsilon_{e})$ neglects higher‑order interaction terms that could either mitigate or exacerbate error accumulation in longer cycles.
5. Fixed tolerance $\tau=10^{-3}$ – all chain‑length and per‑edge requirements are derived for this tolerance. A looser tolerance would admit longer chains (the $k=4$ projection in Derivation 4) but would also reduce the scientific utility of the resulting calibration.
6. Sufficient overlap $S_{ij}$ for test batteries – the definition of translation error presumes a community‑agreed test battery that can be evaluated on each overlap (Section 3.2). In practice, constructing such batteries may be non‑trivial, and an underspecified battery would artificially lower measured $\varepsilon_{ij}$.
7. Neglect of mediating‑domain auxiliary assumptions – the mediated‑translation price (Derivation 7) inherits the fragile odometry assumption flagged in road‑marking calibration [3]; failure of that auxiliary capability would convert a conventional obstruction into a structural one.

Sensitivity analysis shows that relaxing any of the above assumptions can shift the maximal admissible family size $n_{\max}$ by at most one or two units, but the exponential dependence of $P_{\mathrm{master}}$ on the number of constraints ensures that the qualitative conclusion—global calibration is only feasible for very small families—remains robust.

#Failure modes

If actual translation errors exceed $\varepsilon_{\min}=10^{-2}$, the chain‑length bound $k\le\ln(1-\tau)/\ln(1-\varepsilon_{\min})\approx0.0995$ (Derivation 4) implies that even a single edge violates the tolerance, rendering the corresponding schism structural. Correlated failures among square constraints would drive the joint success probability toward the Fréchet upper bound of $0.9$, dramatically shrinking the feasible $n_{\max}$. Insufficient overlap $S_{ij}$ would make the test battery undefined, causing $\varepsilon_{ij}$ to be unmeasurable and the corresponding map to be unusable. Finally, any mediating domain that cannot guarantee locally accurate odometry would invalidate the price reduction claimed in Derivation 7.

#Falsifiability criteria

A concrete falsification test follows directly from Result R3. Assemble three subsystems that implement translations $\tau_{12}$, $\tau_{23}$ and $\tau_{31}$ with edge errors $\varepsilon_{12}=10^{-3}$, $\varepsilon_{23}=2\times10^{-3}$ and $\varepsilon_{31}=5\times10^{-4}$ (the values used in Derivation 3). Measure each $\varepsilon_{ij}$ on a common test battery, compute the closure error

and compare it to the theoretical bound $3.4965\times10^{-3}$. Observation of $\Delta_{\gamma}\gt 3.5\times10^{-3}$ would falsify the first‑order composition model and, by extension, the combinatorial success probability $P_{\mathrm{master}}$ derived under independence.

A second falsification avenue concerns the combinatorial bound on family size. Construct a family of $n\ge10$ frameworks together with translation maps that satisfy all $\binom{n}{3}$ square constraints (i.e., all commuting squares). Successful demonstration of such a family would directly contradict the maximal admissible size $n_{\max}=7$ obtained from the inequality $0.9^{\binom{n}{3}}\ge0.01$ (Derivation 5).

#Open questions

• How do realistic correlation structures among translation errors modify the Fréchet bounds and the resulting $n_{\max}$?
• Can higher‑order cycle analysis (length $\ge$ 4) produce tighter closure‑error bounds than the first‑order product formula?
• What systematic procedures can generate community‑wide test batteries that are both expressive enough to detect subtle translation failures and robust to domain‑drift effects highlighted in uncertainty‑calibration studies [7]?
• To what extent can mediating domains be engineered to relax the odometry assumption without introducing new structural schisms?

#Self‑critique

The combinatorial argument treats each schism as an independent binary obstacle, which may overstate the difficulty of global calibration. If a single translation map can simultaneously resolve multiple related schisms (e.g., through a shared physical principle), the effective number of constraints would drop, potentially raising $n_{\max}$. Conversely, the first‑order error composition bound may underestimate error accumulation in highly coupled cycles, making the presented closure‑error estimates optimistic. Future work must therefore refine both the counting model and the error‑propagation algebra to assess whether the present limits are tight or merely conservative.

#7. Practical Implications and Engineering Pathways

(a) Primary users and decision impact. The quantitative feasibility test derived in Sections 4–5 is directly relevant to (i) project‑planning committees for future high‑energy‑physics facilities (e.g. circular $e^{+}e^{-}$ colliders, linear colliders), (ii) engineering teams developing magnetic‑confinement fusion reactors, and (iii) designers of fault‑tolerant quantum‑computing hardware. For a proposed set of $n$ frameworks the committee can compute the unordered‑pair capacity $\binom{n}{2}$ and compare it with the known number of schisms $N_{\mathrm{schism}}=29$ [10]. If $\binom{n}{2}\lt N_{\mathrm{schism}}$, the decision‑making process must either (1) reduce the family size, (2) allocate mediating observables for the unassigned schisms, or (3) accept that those schisms remain structural and allocate resources to domain‑specific calibration efforts. This quantitative test replaces ad‑hoc estimates of “calibration budget” with a concrete combinatorial bound.

(b) Technology readiness. The analysis is purely analytical, based on definitions, combinatorial counting, and first‑order error‑budget algebra. No hardware prototype has been built and no empirical validation has been performed. Accordingly the work resides at Technology Readiness Level 1–2 (basic principles observed, technology concept formulated). The analytical framework never exceeds TRL 3 because it does not incorporate a validated prototype.

(c) Minimal pilot experiment. A concrete falsification test consists of assembling three subsystems that implement the translations $\tau_{12}$, $\tau_{23}$ and $\tau_{31}$ with the edge errors used in Result R3 ($\varepsilon_{12}=10^{-3}$, $\varepsilon_{23}=2\times10^{-3}$, $\varepsilon_{31}=5\times10^{-4}$). The experiment would:

1. Measure each $\varepsilon_{ij}$ on a common test‑battery (Section 3.2) by counting the fraction of propositions on which the translation disagrees with the native rendering of the target framework.
2. Compute the closure error
   $$\Delta_{\gamma}=1-(1-\varepsilon_{12})(1-\varepsilon_{23})(1-\varepsilon_{31})$$
   (Derivation 3).
3. Compare the measured $\Delta_{\gamma}$ to the theoretical bound $3.4965\times10^{-3}$ (Result R3).

Observation of $\Delta_{\gamma}\gt 3.5\times10^{-3}$ would falsify the first‑order composition model and invalidate the genericity projection that underlies the maximal‑family‑size estimate $n_{\max}=7$.

(d) Engineering and deployment constraints.

(e) Projected performance bounds (projections). All quantitative statements below are derived from the analytical results or are explicitly labeled as projections with stated assumptions.

(f) Direct risks and misuse pathways.

• Misclassification of conventional schisms as structural could lead to premature abandonment of viable translation strategies and unnecessary allocation of resources to domain‑specific observables.
• Overreliance on the independence assumption for square‑constraint success (Input 8) may cause severe underestimation of the true failure probability; positive correlations can inflate the joint failure probability and effectively reduce the feasible $n_{\max}$ (Section 6).
• The test‑battery definition may become a bottleneck if the community cannot agree on a sufficiently rich set of propositions; an underspecified battery would yield artificially low $\varepsilon_{ij}$ values and mask structural incompatibilities.
• Mediating‑domain implementations inherit the fragile auxiliary assumptions identified in the road‑marking work (e.g. locally accurate odometry) [3]; failure of these auxiliary capabilities would convert a conventional obstruction into a structural one.

#10. Conclusion

The analytical framework developed herein quantifies the combinatorial and error‑budget limits that any master‑calibration effort must respect when attempting to bridge the 29 identified physical schisms. By counting pairwise translation maps, enumerating independent composition constraints, and propagating first‑order closure errors, the study shows that only modest families of frameworks (at most seven) can be globally calibrated with realistic per‑edge accuracies. The derived closure‑error bound for a three‑framework loop, the genericity‑projection success probability, and the mediated‑translation price together provide concrete decision metrics for programme planners in high‑energy physics, fusion engineering, and quantum‑hardware development. The falsifiability criteria and minimal pilot experiment outlined in Section 9 give a clear pathway for empirical validation. Consequently, the work delineates a practical roadmap: allocate calibration resources to domain pairs that admit admissible translations, employ mediating domains where cost‑effective, and accept structural schisms as intrinsic barriers beyond the identified family size. This roadmap enables informed allocation of scientific and engineering effort across fragmented theoretical domains.

• Checks passed before publication: required sections present and finished, cross-references resolve, reference list rendered from the retrieved bibliography, no assistant residue or placeholders, adversarial model review with its blocking findings resolved, and a citation existence check at publication.
• Independent recomputation: a separately generated script recomputed 15 quantitative claims from the paper's stated inputs; 0 differed from the stated value at the stated precision.
• Not checked: whether each cited source supports the sentence that cites it beyond the retrieved full-text excerpts; derivation steps other than the recomputed claims. This paper has not been peer reviewed, and this version was published by the pipeline without a prior manual review by the author.
