Paper 103 establishes that any system admitting distinguishable states (C1), real transformation (C2), and determinate persistence verdicts (C3) must be non-transitive under admissible transformation. Restricted transformability is therefore not optional — it is forced by the persistence problem itself. This paper proves that a set of structural categories is not optional under this condition. Each is derived by contradiction: its negation destroys either persistence determinacy, the admissibility of transformation, or the non-triviality of the induced reachability structure. The categories established: partial order on identity classes, asymmetric structural dependence, strict contraction of reachable futures, absence of inverse reachability, and irreversible future-selection. A minimality theorem shows that each is individually necessary: removing any one collapses the persistence structure.

La Profilée (LP) establishes the persistence condition IR = R / (F · M · K) ≤ 1 as the structurally necessary constraint governing identity under real transformation (Paper 103). Subsequent work has established: • the admissibility regime is induced by the persistence problem itself (Paper 122) • no alternative formulation of persistence exists outside trivialisation, indeterminacy, or structural equivalence (Paper 123) • LP defines explicit and exhaustive falsification routes (Paper 124) • the condition is instantiated across structurally independent domains (Paper 118) • LP variables are functional roles admitting operationalisation without collapsing structural abstraction (Paper 119) This paper introduces the Verification Layer: a unified structure demonstrating that LP is not only formally derived and empirically recurrent, but externally verifiable under independent reconstruction and prospectively testable through ex-ante prediction. The result is not an additional argument. It is the closure of the validation space.

Papers 103, 122, and 123 establish that the persistence problem induces its admissibility regime (C1–C3), the unique admissible persistence structure is IR = R/(F·M·K) ≤ 1, and no alternative formulation of persistence exists outside trivialization, indeterminacy, or structural equivalence. This paper addresses a different question: what would be required to falsify La Profilée? The result is precise: any successful falsification must target one of a small set of structural points. Each point imposes a strong constraint — either the persistence problem itself collapses, or a contradiction must be demonstrated within a formally derived necessity, or a counterexample must violate a cross-domain invariant. The paper defines the falsification pressure of LP: the minimal conditions any refutation must satisfy.

Paper 122 establishes that the admissibility conditions of the persistence problem (C1-C3) are not chosen but structurally induced by the possibility of forming a persistence verdict at all. This paper addresses the final remaining question: can persistence be formulated coherently under a different admissibility regime? The result is negative. All alternative formulations of persistence fall into one of three classes: (1) Trivialization — persistence is guaranteed and the problem disappears; (2) Indeterminacy — persistence cannot be decided; (3) Equivalence — the formulation reduces to the LP structure. No fourth class exists. Therefore, the LP admissibility regime is not one possible formulation of persistence. It is the only structurally coherent formulation of the problem.

Structural forcing results operate within an admissibility regime. It is commonly assumed that such regimes are given or chosen, and therefore cannot be validated against reality from within the method that uses them. This paper addresses a prior question: are the admissibility conditions of the persistence problem optional, or are they themselves structurally forced? This paper shows that C1-C3 are not modeling assumptions but are induced by the possibility of forming a persistence verdict at all. The admissibility regime of La Profilée (LP) is not externally given. It is the minimal structure under which the persistence problem exists. LP does not derive a law within a chosen regime. It identifies the unique structure under which the regime itself becomes definable.

La Profilée (LP) establishes the persistence condition IR = R/(F·M·K) ≤ 1 as the unique structure governing persistence under real transformation (Paper 103). Paper 117 further shows that this structure follows from the minimal conditions required for persistence to be a meaningful concept. Paper 118 establishes that this condition is recurrently instantiated across multiple independent domains. This paper clarifies the epistemic status of these results. It distinguishes structural necessity from ontological claim and establishes a precise boundary: structural derivations determine what must hold for coherent description, while empirical observations determine where such structures are instantiated. Neither step alone nor in combination establishes that reality is identical with the derived structure. The result is a clarification, not a weakening: LP is established as a structurally forced and empirically recurrent constraint on persistence, while the ontological status of that structure remains outside the scope of rational derivation.

La Profilée (LP) establishes that any system undergoing real transformation persists if and only if transformation pressure does not exceed integration capacity: IR = R/(F·M·K) <= 1 (Paper 103). That result is formal. This paper addresses a separate question: whether this structurally derived condition is instantiated across real systems. Across thermodynamics, biological systems, engineered structures, information systems, and socio-technical organisations, a consistent pattern is observed: systems maintain identity only within capacity limits and undergo structural breakdown when these limits are exceeded. No examined domain exhibits sustained persistence under conditions analytically identified as IR > 1. The result is not a statistical claim but a structural regularity: across independent domains, persistence is consistently observed within capacity bounds and breakdown is consistently preceded by their violation. LP is therefore not only structurally unavoidable in formal analysis, but empirically recurrent across domains where persistence has been examined.

La Profilee (LP) derives the persistence condition IR = R/(F·M·K) <= 1 from three conditions: distinguishability (M1), real transformation (M2), and determinability of persistence (M3). This paper establishes what follows from the minimality of these conditions. M1-M3 are not empirical assumptions about this world. They are the minimal conditions under which the question "does this system remain the same system?" can have a determinate answer. No subset of them is sufficient. None can be replaced by something weaker. Together they are the minimal sufficient set for the persistence question to be well-posed. Wherever persistence is a meaningful concept, M1-M3 hold. Wherever M1-M3 hold, IR <= 1 is forced. LP therefore does not operate within a chosen descriptive regime. It operates at the level of conditions for persistence to be thinkable at all.

The Origin: a new watch architecture Marc Maibom designed a new architecture for a watch — purely as a design process, without theoretical intent. The aim was a silhouette with its own identity, not traceable to the established archetypes of the watch industry. No model, no hypothesis. Only the search for a form. Only later did it become visible: the new watch architecture resembled a watchmaker seen from above at the bench. Stable frame. Open centre. The body holds, the hands act. The analogy was not the intention — it was a confirmation. The Transformation Posture Give a child a drawing pen for the first time. They open their arms. The hands move into the space in front of the body. No one has to teach them. The same form everywhere. Keyboard. Steering wheel. Paintbrush. Greeting. Embrace. The body forms the frame — the arms open the space in front of it. What happens there differs each time. The structure is always the same. In an embrace, two people simultaneously open that space toward each other. Both remain themselves. Both are connected. At a concert the same thing on a larger scale. The band toward the front of the stage. The audience toward the band. Energy, attention, affection — in both directions. Nobody merges. Nobody disappears. The frame holds. What flows, flows. This posture has no name. Until now. La Profílée carries this structure as form. Not as illustration — as object. Stable frame. Open centre. Coupling between them. The first scale-invariant metadesign A second property became visible when working further with the form: the same frame could accommodate many different modules. An analogue watch. A digital one. A smartwatch. A shelf. A building. One form, endless expressions. This is not a modular system in the conventional sense. It is a metadesign — an architecture that does not describe one product but the condition under which any number of products can arise. Identity and function are separated. The frame carries what endures. The module carries what changes. The coupling defines how both work together without one destroying the other. Sustainability and circularity are not goals of this architecture — they are its consequence. Obsolescence is not a material problem. It is an architectural one.

This paper derives decision principles from the structural framework of La Profílée. Decision is not treated as optimization under uncertainty, but as action under constrained future possibility and persistence conditions. The central result is a derivation of exactly four minimal structurally forced decision regimes from two binary, independent structural questions. The derivation parallels the Q1–Q3 exhaustivity argument of Paper 111: the two decision questions Q_D1 and Q_D2 are jointly exhaustive and pairwise independent, yielding a 2×2 partition of the decision space into four irreducible regimes. Each regime carries a specific admissibility constraint on action, derived from the persistence condition IR ≤ 1 and the integration trajectory T_I. The result establishes decision as navigation under structural constraint — not maximization of expected outcomes.

Within the La Profílée (LP) framework, temporal order is not assumed as a primitive. It is the structural ordering induced by restricted transformability under persistence conditions. Building on the formal derivations of Papers 111 and 112, this paper establishes that temporal order, direction, and informational asymmetry arise from the same underlying structural constraint. This paper is a position statement, not a new derivation. The formal results are in Papers 111 and 112. This paper states their structural consequence directly. Scope. This paper establishes structural necessity within the LP admissibility class — what follows from the persistence conditions M1-M3. Whether those conditions are identical with reality's final constitution is a question this paper does not address. The results hold within the structural framework of LP.

This paper derives information as a structural consequence of restricted transformability under persistence conditions. It does not define information as uncertainty over outcomes. Instead, it shows that for any system admitting determinable states, admissible transformations, and persistence constraints, the reachable state space contracts along the induced structural order. This contraction defines structural information as the reduction of future possibility: Σ(C) := −ln(|Reach(C)| / |S|) Three results are established. First, structural information is monotone increasing along the structural time order (Reachability Contraction Theorem). Second, structural information is coupled to persistence load near the boundary IR → 1: as the system approaches collapse, future possibility shrinks and structural information accumulates. Third, structural information is categorically distinct from Shannon entropy: it measures the contraction of the possibility space itself, not uncertainty over outcomes within a fixed space. The result establishes information as a derived property of the same underlying condition that generates time and directionality in Paper 111: restricted transformability under persistence.

This paper derives time as a structural consequence of restricted transformability under persistence conditions. It does not assume time as a primitive parameter. Instead, it shows that determinable existence under real transformation induces a reachability structure whose condensation yields a directed acyclic graph, establishing a partial order. From this partial order structure, three irreducible temporal components are derived and shown to be exhaustive within the persistence problem. (T1) Order time, arising from reachability depth in the condensation DAG. (T2) Load time, arising from proximity to the persistence boundary IR = 1. (T3) Integration time, arising from structural reconstruction dynamics along DAG paths. T_struct(C) = (T_O(C), T_L(C), T_I(C)) = (DAG depth, 1/D_c(C), ∇_O I(C)) The exhaustivity of these three components is established by a functional analog of the Q1–Q3 exhaustion argument in Paper 103 (PAT Lemma 4): any temporal function on C must answer at least one of three questions about the system's position, stress, or trajectory, and these questions are pairwise non-merging and jointly exhaustive within the persistence problem. Scalar time emerges as a regime-dependent projection of this field. The result establishes time, directionality, and structural information as derived properties of the same underlying constraint: restricted transformability under persistence.

La Profílée establishes IR = R/(F·M·K) ≤ 1 as the unique admissible persistence law. This paper proves that Flourishing — the regime dR/dt < d(FMK)/dt with IR < 1 — is the only growth regime compatible with persistent identity. All other growth forms either drive IR → 1 (structural exhaustion) or IR > 1 (collapse). This paper additionally identifies a non-obvious structural prediction: the Pre-Collapse Signature. Systems approaching IR = 1 from below exhibit a specific oscillatory pattern — alternating phases of growth and contraction — before structural collapse. This signature is structural, not contingent: it follows from the absence of reserve at IR near 1 and the fact that growth-induced R increases cannot be absorbed. The Pre-Collapse Signature is observable independently of the cause of collapse and provides a structural early-warning indicator.

This paper proves that the admissible parameter region Θₚ is exactly the intersection of the structural constraints derived in Papers 106–108: Θₚ = C_M ∩ C_KF ∩ C_KR. Fine-Tuning is the parameter-space projection of this intersection. This paper additionally identifies a non-obvious structural prediction: the Constraint Coupling Prediction. Because the same physical constant can simultaneously affect multiple LP structural variables (α affects both K and F; G affects both K and R), the boundaries of the individual constraint regions are not independent in parameter space. There exist iso-persistence curves — paths through parameter space along which compensatory variations keep θ ∈ Θₚ. This structural coupling between constraint dimensions is a prediction of the intersection structure of Θₚ that has no equivalent in standard Fine-Tuning accounts, which treat each constant's range as independently determined.

The Fine-Tuning of G is standardly framed as a condition for star formation and long-lived structure. This paper derives a structurally prior result: G constrains both K(θ) (global integration) and R(θ) (transformation pressure), and their joint condition IR = R/(F·M·K) ≤ 1 must be satisfied. LP adds a non-obvious prediction: the Structural Fragility Zone — the region of parameter space where IR < 1 is satisfied but IR is near 1. Systems in this zone are persistence-admissible but lack structural reserve. They exhibit specific observable signatures (high perturbation sensitivity, inability to sustain growth, collapse under small shocks) that are absent in the collapse regime and distinct from the flourishing regime. Standard physics identifies a binary: structure forms or it does not. LP identifies three distinct structural regimes.

The Fine-Tuning of α is standardly framed as a condition for atomic and molecular stability. This paper derives a structurally prior result: α constrains both K(θ) and F(θ) simultaneously, and these constraints are not independent — they co-degrade. The non-obvious structural prediction is the K–F Co-Degradation Prediction: there is no regime in which K fails while F holds, or vice versa, for electromagnetic interaction. K and F degrade together as α moves away from the admissible interval, at a rate determined by their structural coupling. Standard physics treats atomic stability and molecular integration as distinct phenomena. LP derives them as jointly constrained manifestations of the same structural condition.

The Fine-Tuning of the strong nuclear force is standardly framed as a condition for nuclear stability. This paper derives a structurally prior result: the strong force constrains M(θ), the transformation-processing capacity, via the depth of achievable composite hierarchy. The admissible range of the strong force is not merely "nuclei exist" — it is "the full composite ladder from nucleons to atoms to molecules is sustainable." LP adds a non-obvious prediction: the M-Hierarchy Depth Prediction — the composite depth achievable in a universe is a monotone function of proximity to the M-admissible range. Universes near the boundary of M-admissibility achieve shallower composite hierarchies. This is distinct from the standard binary "stable nuclei yes/no."

This paper provides the first explicit bridge between the structural persistence law of La Profílée and a standard cosmological fine-tuning result. Building on Paper 104, it shows that in ΛCDM cosmology the cosmological constant Λ functions as a Level-1 parameter that constrains K, the cross-scale integration condition. The standard upper bound on Λ is a persistence bound. This paper additionally develops a quantitative toy model for the K-Erosion Hierarchy — the structurally determined order in which cosmological scales lose K-admissibility as Λ increases. The model derives K_eff(ℓ, Λ) from linear structure formation theory and shows that Λ_K(ℓ) ∝ ℓ^(−2.22): larger scales lose K-admissibility at smaller Λ values. This is a falsifiable, scale-specific prediction absent from standard Fine-Tuning accounts.

This paper states, proves, and closes the Persistence Admissibility Theorem (PAT) and establishes the structural unavoidability of La Profílée. It supersedes Papers 81 v1/v2 and incorporates Paper 82 (Admissibility Necessity), closing all previously open precision points. Part I (Sections 1–5) establishes PAT: within the full admissibility class C defined by Conditions 1–7, the unique global persistence condition is R ≤ F·M·K. Three precision improvements over PAT v2: (1) Sub-Lemma 2.1 formally derives countable order-density from Condition 4 rather than assuming it; (2) Lemma 4 closes the exhaustivity of the triadic architecture through Q1–Q3 functional exhaustion and B1–B4 systematic exclusion of fourth roles; (3) the C₀→C₁ transition is established internally rather than deferred to Paper 82. Part II (Sections 6–9) establishes the Unavoidability of the Persistence Structure: F, M, K are not variables chosen to model persistence — they are the logical invariants of any possible persistence verdict. Any theory forming persistence verdicts satisfying Conditions 1–3 already contains F, M, K in the structure of its judgments. The admissibility class C is not assumed — it is induced. LP is not derived from persistence theories. Persistence theories are constrained projections of LP.

The Fine-Tuning problem asks why the fundamental physical constants of the universe are so precisely calibrated that any significant deviation would preclude the formation of complex structure. Standard responses invoke anthropic selection, multiverse hypotheses, or design. This paper derives a structurally prior resolution. Paper 103 proves that IR = R / (F·M·K) ≤ 1 is the unique admissible form of any global persistence condition. Any universe exhibiting persistent structure necessarily satisfies the persistence condition IR = R / (F·M·K) ≤ 1. The observed universe exhibits stable, law-governed structure across cosmological time. Therefore the observed universe falls within the scope of the persistence condition, because it exhibits the admissibility features under which the condition is unavoidably instantiated. Fine-Tuning is not merely a coincidence. It is the parameter-space form of the persistence condition at cosmological scale: the restriction that any universe must satisfy to constitute persistent structure at all. A key structural clarification: The variables of the persistence condition are not physical objects. They are the irreducible structural conditions that must be satisfied for persistence to be possible at all. Physical constants do not correspond to the variables of the persistence condition. They determine whether the minimal structural conditions required for persistence can be satisfied at all. This two-level distinction is the central methodological contribution of the paper and blocks the standard objection that the variables of the persistence condition are being naively identified with physical constants. Critically, Θₚ is a proper and non-trivial subset of the kinematically consistent parameter space Θ (established by the logical independence of F, M, K): parameter configurations outside Θₚ are structurally excluded as systems, not merely unobserved.

This paper states, proves, and closes the Persistence Admissibility Theorem (PAT) and establishes the structural unavoidability of La Profilée. It supersedes Papers 81 v1/v2 and incorporates Paper 82 (Admissibility Necessity), closing all previously open precision points. Version 2 incorporates five reviewer-hardening additions to the original P103 argument: (1) explicit proof that F, M, K are not re-labelings but the irreducible logical invariants of any persistence verdict; (2) clarification that the classification into three transformation structures is structural and non-evaluative, not presupposing M3; (3) the functional class exhaustion proof establishing multiplicativity as the only form in the admissible class, not merely the unique representative; (4) the separation of universality from empirical coverage; (5) the residual condition argument establishing that IR ≤ 1 is not a tautology but the result of eliminative closure. Part I (Sections 1–5): PAT — within the full admissibility class C defined by Conditions 1–7, the unique global persistence condition is R ≤ F·M·K. Key improvements over v1: Sub-Lemma 2.1 formally derives countable order-density from Condition 4; Lemma 4 closes the triadic architecture through Q1–Q3 exhaustion and B1–B4 exclusion; the C₀→C₁ transition is established internally; C3 is proved as a structural consequence of C1+C2, not an independent axiom. Part II (Sections 6–9): Unavoidability — F, M, K are logical invariants of any possible persistence verdict, not variables introduced into a model. The admissibility class C is not assumed — it is induced. LP is not derived from persistence theories. Persistence theories are constrained projections of LP.

La Profílée (LP) derives the persistence condition IR = R/(F·M·K) ≤ 1 from three minimal axioms without domain-specific assumptions. This paper establishes formal structural equivalence between LP and three independent physical stability theories: thermodynamics, fluid dynamics, and quantum decoherence. Section 0 proves the Representation Uniqueness Theorem: any stability theory admitting a dimensionless load/capacity ratio, non-substitutable capacity factors, and monotone ordering necessarily reduces to IR ≤ 1 under admissible variable identification φ. This closes the identification question: φ is not chosen for convenience but forced by the admissibility conditions of any well-formed stability theory. Section 1 (Thermodynamics): Lyapunov stability ⇔ IR ≤ 1 under φ_T via Separability Lemma; phase transitions = IR = 1; Onsager coupling = K; Prigogine minimum entropy production = Flourishing. Section 2 (Fluid Dynamics): Re/Re_c = IR under φ_f; laminar-turbulent transition = IR = 1; Representation Theorem (Reynolds as class member). Section 3 (Recovery): F_f → M_f → K_f is the unique admissible relaminarization sequence; all five alternatives are structurally void. Section 4 (Quantum Decoherence): decoherence rate as R, coherence maintenance capacity as IK; quantum-classical transition = IR = 1; Lindblad dynamics under IR ≤ 1 condition. The convergence of three independent physical theories on the same structural condition is non-trivial: thermodynamics is grounded in statistical mechanics, fluid dynamics in continuum mechanics, quantum decoherence in Hilbert space formalism. Their structural equivalence to IR ≤ 1 is not analogical but formal under the admissibility conditions established in Section 0. The significance of the convergence lies not in the multiplicity of examples but in the independence of formal origin: a quadratic entropy-production form, a continuum-force ratio, and a Lindblad decoherence semigroup do not share a native mathematical language. Their reduction to the same persistence order under A1–A5 is therefore structurally non-trivial.

Every system undergoes change. Yet some systems remain the same. This paper addresses the fundamental question: under what conditions does identity persist under real transformation? We show that this question admits a single structural answer. From three minimal assumptions — distinguishability, real transformation, and decidability — a unique structure follows: identity-bearing structure, transformation-processing capacity, and their coupling. These roles combine into a single capacity measure, yielding a necessary and sufficient condition for persistence. This condition is not a modeling choice. It is the only admissible form consistent with the persistence problem itself. This paper derives LP from minimal axioms and establishes the dynamic persistence equation. Parts I–XIII constitute the formally closed core (Level A): derived from M1–M3 alone. Parts XIV–XXIII constitute formally derived extensions (Level B), applying M1–M3 to multi-system environments and higher-order structures. All structural hypotheses are formally closed. LP is precisely falsifiable. Physical stability results in thermodynamics, fluid dynamics, and quantum mechanics are special cases of IR ≤ 1.

La Profilée (LP) is most often read as a theory of collapse: when transformation load exceeds integration capacity, systems fail. This reading is correct but incomplete. The persistence condition IR = R / (F·M·K) ≤ 1 describes two faces of the same structural reality. One face is collapse. The other is growth. This paper makes the positive face explicit. A system operating well below the threshold — IR significantly below 1 — is not merely surviving. It has structural reserve: the capacity to absorb more transformation, take greater risks, and use change as the material of development rather than a threat to identity. The same three structural components that determine collapse — Frame integrity, transformation-processing capacity, and coupling quality — also determine the conditions under which a system can genuinely grow. The paper establishes four positive structural theorems: the Reserve Theorem (structural slack enables growth), the Development Theorem (genuine development requires stable F), the Transformation Advantage Theorem (high F·M·K systems benefit structurally from transformation that destroys low-capacity systems), and the Reconstitution Theorem (recovery follows the same structural logic as growth). Each theorem is illustrated across domains: organizations, persons, and physical systems. Growth is not the opposite of collapse. It is the same structure under different capacity conditions. The result is a complete structural account of the persistence condition as both constraint and enabler. LP does not merely explain why systems fail. It explains what structural conditions make genuine flourishing possible — and why flourishing and collapse are not opposites but expressions of the same underlying law.

Paper 89 established that personal identity is structurally determinate under La Profilée’s (LP) persistence condition IR = R / (F·M·K) ≤ 1, and identified the operationalization of Frame (F) for persons as an open question. This paper closes that question in three steps. First, F, M, K, and R are operationalized for the human person with a concrete indicator set: F as self-referential structural integration, M as transformation-processing capacity, K as coupling coherence between Frame and Module, and R as total transformation load. Each variable is defined with independently observable indicators satisfying the Operational Closure Principle. Second, the operationalization is grounded in empirical developmental psychology. Luyckx et al.’s (2008) dual-cycle model of identity formation and Marcia’s (1966/Kroger & Marcia, 2011) identity status framework provide a well-validated empirical base from which F, M, K, and R can be independently estimated. The adolescent identity crisis — the transition from Moratorium to Identity Achievement — is analyzed as a structural case: IR rises above 1, F remains above F_crit* throughout, and IR returns to ≤ 1 at reintegration. LP’s verdict (same person throughout) is structurally derived and contrasted with Parfit’s framework, which cannot account for the persistence verdict without additional stipulation. Third, structural phenomena — mental illness, development, identity crisis, and death — are shown to be unified configurations of F, M, K, and R rather than independent categories. The result is a complete, empirically grounded structural account of personal persistence. The human person is not an exception to the LP persistence condition. It is its most revealing case.

Derek Parfit’s reductionist account of personal identity holds that persons just are physical and psychological continuity relations, that identity is not what matters, and that certain cases — fission, teletransportation, gradual replacement — admit no determinate identity verdict. This paper argues that Parfit’s position is formally untenable once the structural conditions for any law-governed persistence description are made explicit. La Profilée (LP) establishes that any system admitting a well-defined persistence problem under real transformation must satisfy seven admissibility conditions (C1–C7), and that these conditions entail a unique structural persistence condition: IR = R / (F·M·K) ≤ 1. Three consequences follow. First, the Parfitian indeterminacy thesis — that fission cases have no determinate answer — is shown to be a category error: it confuses the underdetermination of psychological content with the underdetermination of structural identity. Second, the claim that ‘what matters’ is psychological continuity, not identity, conflates two structurally distinct levels. Third, LP’s Frame non-substitutability theorem shows that Parfit’s fission cases have a determinate structural verdict: F cannot be divided without passing below the critical threshold F_crit*, and both post-fission continuants are therefore new systems, not continuations of the original. Parfit was right that psychological continuity is not sufficient for identity. He was wrong about what the correct account is.

Papers 87 and below define the formal core of La Profilée. Structural time — the emergence of temporal direction and structural progression rate from LP’s minimal conditions — was developed in a parallel series of papers from February–April 2026. This document integrates those papers into the LP core by showing where each concept maps to the Core Specification definitions (Paper 87). These works are hereby integrated into the LP series as the structural time layer of the Core Specification (Paper 87, D1–D10). No new theorems are introduced. This is a navigation document.
