Holographic Closure Capacity and Transactional Exhaust

Status note, 5 September 2026 — the scalar mass is an explicit, measurable input. Every calculation in this paper stands unchanged, evaluated at m_s = 3.94 × 10⁻²³ eV. What has changed is that value’s standing. From the Theory Edition (First Principles V9.7.2) the framework carries m_s as its one free scale: the theory states how each prediction depends on it, and specifies how it is to be measured — the knee at τ_c = ℏ/(m_sc²) in an activation-timing distribution, never a centroid (V9.7.2 §III.B). That is the same footing as the graviton mass in massive gravity or the coupling in scalar–tensor gravity — a scale the theory fixes the dependence on and hands to experiment. Study 21 established it by auditing every internal route for fixing the mass. Results below are accordingly conditional on the evaluation scale; where this paper calls the mass “derived”, read “evaluated at”, the figure being the historical association-implied value.

A Conjectural Extension of the Selective Transient Field Framework

Z. Paz
Version 1.3 — 22 August 2026

STATUS — CONJECTURE PROGRAM. This paper is an architectural proposal, not a theorem-grade result: it states hypotheses, the theorem chain that would be required to establish them, and the falsifiers that would reject them. Its claim ledger (§11) assigns every statement its status, including the false ones. It sits downstream of the four results named in §1 and modifies none of them. Nothing in it may be cited as established STF physics.

Abstract

The Selective Transient Field (STF) framework proposes that a physical history becomes actual through topological closure of retarded and advanced causal sectors. Its Closure–Capacity Correspondence further proposes that closure is possible only when the available transactional channel capacity is at least as large as the unresolved information that must be stabilized. This paper asks whether that correspondence can be combined with horizon entropy to define a finite universal closure capacity, and whether failure to close can leave a gravitating but transactionally inaccessible residue.

The result is a disciplined conjecture program rather than a completed theory. The Gibbons-Hawking entropy of an asymptotic de Sitter horizon constrains the number of distinguishable gravitational states under its usual assumptions. It does not by itself count transactions, measure a causal channel, or establish that the cosmic ledger fills monotonically. The STF normalization \(4\pi^2\), the integer winding number \(w\), one Shannon bit, and a thermodynamic entropy increment are mathematically different quantities. Converting one into another requires a physical coding theorem that has not yet been supplied.

We therefore formulate the Holographic Closure-Capacity Hypothesis conditionally. A finite transaction bound follows only if each independently distinguishable closure writes a non-reusable physical record to a finite boundary algebra. We then formulate the Transactional Exhaust Hypothesis: a failed or inaccessible closure sector may retain a conserved stress tensor while decoupling from ordinary record-forming interactions. Merely gravitating is not sufficient to reproduce cold dark matter. A viable exhaust sector must derive \(w\simeq0\), negligible sound speed and anisotropic stress, stable clustering, gravitational lensing, and the observed cosmological power spectra. It must also be related explicitly to, or distinguished from, the existing STF ultralight oscillating-scalar dark-matter candidate.

Between the universal bound and the proposed exhaust branch lies a physically important positive-margin regime: living and constructed systems that preserve local records. Organisms, archives, institutions, cities, and computational networks increase storage, transmission, redundancy, and error-correction capacity while reducing unresolved uncertainty through shared rules and models. They do not defeat terminal neutrality or the second law. They use free-energy gradients and export entropy to delay the loss of accessible records. Civilization can therefore be interpreted, conditionally, as a distributed record-preserving architecture that stitches finite local clocks into an intergenerational chronology.

This positive-margin interpretation implies a Maintenance–Temporality Principle. Biological and civilizational record clocks persist only while energy-funded repair and error correction keep pace with degradation. If maintenance has a nonzero free-energy cost and accessible gradients eventually become insufficient, the organized local clock must be finite even though its material constituents remain embedded in universal time. Universal HAPPENS supplies the arena; maintained systems participate in it only conditionally and for finite intervals.

The same structure permits a quantitative resource trajectory. Accessible exergy—not total conserved energy—obeys a balance between initial stocks, external capture, biological use, and irreversible loss. Extinction by energy depletion occurs not necessarily when the stock reaches zero, but when the available maintenance power remains below the repair threshold longer than the system’s reserves can buffer. We derive the general depletion integral, a simple finite-stock bound, and the coupled resource-population equations needed before an extinction time can be calculated.

The paper identifies the exact theorem chain needed to turn the proposal into physics: a closure coding map, an accessibility and reuse law for boundary records, a covariant exhaust action, a conservation and transfer law, and a cosmological perturbation analysis. Until those steps are completed, holographic closure capacity and transactional exhaust remain falsifiable architectural hypotheses, not consequences of topological closure.

1. Scope and dependency firewall

This paper begins downstream of four STF results and does not modify their status:

1. The Clock-Separation Theorem distinguishes the oscillating internal phase from universal temporal ordering.
2. The Universal Clock Carrier selects a boundary-conditioned CMC normal as the preferred nonpropagating carrier candidate.
3. The Universal Embedding Principle constructs a Born- and Bell-compatible quantum embedding but does not derive the Born rule.
4. Topological closure supplies a retarded/advanced winding normalization \(\int\omega_R\wedge\omega_A=4\pi^2\), but does not select one outcome from the histories it normalizes.

Nothing in the present conjecture can repair an open universal-to-local gluing theorem, an open CMC existence theorem, or an absent outcome-selection rule. Closure capacity is a proposed additional layer: it asks how much unresolved information a physical boundary channel can stabilize. Transactional exhaust is further downstream: it asks what dynamical residue, if any, remains when that capacity condition fails.

The separation is essential. Horizon thermodynamics must not be used to turn a quantum compatibility result into a Born-rule derivation, and the existence of a gravitating residue must not be inferred from a metaphor about information loss.

2. The standard holographic input

2.1 De Sitter horizon entropy

For a four-dimensional asymptotic de Sitter spacetime with cosmological constant \(\Lambda>0\), the horizon radius is

\[ r_{\rm dS}=\sqrt{\frac{3}{\Lambda}}, \]

and the horizon area is

\[ A_{\rm dS}=4\pi r_{\rm dS}^2=\frac{12\pi}{\Lambda}. \]

The Gibbons-Hawking entropy is therefore

\[ S_{\rm dS} =\frac{k_Bc^3A_{\rm dS}}{4G\hbar} =\frac{3\pi k_Bc^3}{G\hbar\Lambda}. \]

In units \(k_B=c=\hbar=1\),

\[ S_{\rm dS}=\frac{3\pi}{G\Lambda}. \]

If the entropy counts a finite number of distinguishable states, the associated state-space estimate is

\[ \ln\dim\mathcal H_{\rm dS} \lesssim\frac{S_{\rm dS}}{k_B}. \]

This is the legitimate holographic starting point. It is a bound on distinguishable states or boundary information under the assumptions of the de Sitter entropy interpretation.

2.2 What the entropy bound does not say

The same bound does not immediately determine:

• the number of physical events occurring during cosmic history;
• the number of times a finite memory can be reused;
• the complexity or duration of a history encoded by one boundary state;
• the rate at which closure information can be transmitted;
• the entropy written by one STF transaction; or
• whether the asymptotic universe is exactly de Sitter.

A finite state space can support arbitrarily long sequences unless a separate irreversibility or no-reuse law is imposed. Conversely, a single state may encode correlations among many events. Horizon entropy is therefore not a cumulative event counter.

Status. The horizon entropy formula is standard. Its interpretation as an STF transaction budget is not.

3. Four quantities that must remain distinct

The proposed correspondence involves four objects that are easily conflated.

3.1 Topological normalization

For one completed retarded/advanced torus,

\[ \frac{1}{4\pi^2} \int_{T^2_\gamma}\omega_R\wedge\omega_A=1. \]

The factor \(4\pi^2\) normalizes the cup product. It is dimensionless and does not by itself carry units of entropy, channel capacity, or energy.

3.2 Winding number

The integer

\[ w\in\mathbb Z \]

classifies a homotopy sector. A fixed value \(w=1\) certifies one winding class. A value known in advance carries no Shannon information by itself. Information appears only when a receiver must distinguish among alternative values or histories according to a specified probability distribution.

3.3 Shannon information

For an unresolved set of alternatives with probabilities \(p_i\),

\[ H_{\rm unresolved} =-\sum_i p_i\log_2p_i. \]

Two equiprobable alternatives require one bit to label. This is the rigorous core of the Theorem of the Unknown. It does not show that nature uses a winding number as that label.

3.4 Thermodynamic entropy

A physical memory reset or irreversible record can carry a thermodynamic cost, but the cost depends on the implementation, temperature, accessibility, and logical operation. A topological label does not become a thermodynamic entropy increment merely because both can be counted.

The missing bridge is thus not a numerical conversion factor. It is a physical map among a homotopy class, a code alphabet, an accessible channel, and a boundary record.

4. The Closure–Capacity Correspondence

4.1 The schematic inequality

Let \(H_{\rm unresolved}\) denote the information needed to distinguish the globally admissible completions left unresolved by local data. Let \(C_{\rm closure}\) denote the usable capacity of the physical channel that anchors or certifies closure. The proposed condition is

\[ C_{\rm closure}\ge H_{\rm unresolved}. \]

The corresponding margin is

\[ M_{\rm cl}=C_{\rm closure}-H_{\rm unresolved}. \]

Within the conjecture:

• \(M_{\rm cl}>0\) is a supercritical closure regime;
• \(M_{\rm cl}=0\) is the proposed critical-closure surface; and
• \(M_{\rm cl}<0\) is an unresolved or non-closing regime.

These inequalities become physical only when both sides are defined for the same channel use, bandwidth, time interval, and logarithmic base.

4.2 Why the data-rate theorem is not yet an STF theorem

In control theory, a data-rate theorem relates stabilization of a specified unstable dynamical system to the capacity of a specified communication channel. The theorem assumes identifiable states, dynamics, messages, channel uses, noise, encoder, decoder, and stabilization criterion.

The STF analogy currently lacks several of these elements:

1. the sender and receiver of the closure record;
2. the physical carrier and its accessible observables;
3. the channel-use interval;
4. the noise and error model;
5. the code mapping histories to records;
6. the dynamical quantity being stabilized; and
7. the covariant observable representing \(C_{\rm closure}\).

The external data-rate theorem can guide the construction, but it cannot be transferred by notation alone.

4.3 The Closure Coding Theorem target

A completed STF theorem would require a map

\[ \mathfrak C: \mathcal H_{\rm admissible} \longrightarrow \mathcal A_{\partial}, \]

from admissible global histories to distinguishable elements of a physical boundary algebra \(\mathcal A_{\partial}\). It would then have to establish:

\[ I(\mathfrak C) \ge H_{\rm unresolved}, \]

with a covariant accessibility rule and a demonstrated relationship to the STF winding sector. Only then would “one winding supplies one bit” be more than a structural conjecture.

Status. The one-bit label theorem is elementary and exact. The physical winding-to-bit exchange is open.

5. Constructed order: life, civilization, and local record persistence

5.1 The positive-margin branch

The Closure–Capacity Correspondence is usually introduced through its failure condition,

\[ C_{\rm closure}<H_{\rm unresolved}. \]

That emphasis leaves out the complementary regime in which a system actively maintains enough capacity to preserve and propagate its records. Over a specified interval \(\Delta t\), define schematically

\[ M_{\rm loc}(\Delta t) =C_{\rm record}(\Delta t) -H_{\rm unresolved}(\Delta t). \]

Here \(C_{\rm record}\) is the usable storage, communication, replication, and error-correction capacity available to a local record network, while \(H_{\rm unresolved}\) is the information required to distinguish the continuations or reconstruct the records relevant to that network. Both terms must be measured over the same interval, with the same units and accessibility conditions.

The proposed positive-margin regime is

\[ M_{\rm loc}>0. \]

In that regime, a system can continue to form, repair, and transmit readable records despite noise and degradation. This is an interpretive application of the closure-capacity structure, not yet a calculation: neither term has been derived as a covariant STF observable for organisms or cities.

5.2 How constructed systems change both sides of the margin

Human construction does more than concentrate channel capacity. It also compresses uncertainty.

Physical infrastructure primarily raises \(C_{\rm record}\). Shared rules, models, and institutions also lower \(H_{\rm unresolved}\) by reducing the number of continuations that actors must treat as equally admissible. A legal system, software protocol, or architectural standard is therefore not merely a stored object. It is an uncertainty-reduction mechanism.

This supplies a precise version of the analogy between a physically anarchic substrate and constructed society. “Anarchic” cannot mean that the substrate lacks law or structure: physical law already constrains it. It means that the substrate contains no central purposive authority assigning human norms. Institutions add a local normative and informational order within, rather than outside, the geometric order.

Civilization is an extreme example, not a new fundamental category. Organisms, ecosystems, immune systems, genetic inheritance, and technological networks are all nonequilibrium structures that preserve distinctions against noise for a finite duration. The conjecture should therefore apply, if at all, to a general class of record-forming and error-correcting systems rather than uniquely to humanity.

5.3 The thermodynamic price of preservation

A city, organism, or server farm is not a permanently low-entropy exception to the second law. It is an open, nonequilibrium system that maintains organization by consuming free energy and exporting entropy. For a system plus its environment,

\[ \dot S_{\rm total} =\dot S_{\rm system}+\dot S_{\rm environment} \ge0. \]

The system may maintain or increase local organization only while the environment receives sufficient heat and degraded free energy. Record preservation therefore has a material cost: maintenance, cooling, correction, copying, and replacement.

This reverses the simplest “rebellion against the universe” picture. Human construction does resist the local loss of readable distinctions, but it pays for that resistance through the same entropy production that drives the wider thermodynamic arrow. A server farm keeps records accessible by dissipating energy. A city remains organized through a continuous metabolism of energy, materials, repair, and replacement.

The resulting relationship is not contradiction but friction:

Constructed order spends the universe’s available free-energy gradients to keep selected portions of its history readable for longer.

5.4 Civilization as an intergenerational record clock

An individual biological record clock is finite. Its cessation does not halt the physical evolution of the underlying matter, but it ends that organism’s integrated production and interpretation of records. Externalized records can nevertheless enter the internal clocks of later systems:

\[ \tau_1 \longrightarrow R_{12} \longrightarrow\tau_2 \longrightarrow R_{23} \longrightarrow\tau_3 \longrightarrow\cdots . \]

The connecting records \(R_{ij}\) may be biological inheritance, language, texts, software, institutions, buildings, or technical practices. They prevent each new local clock from beginning without a past.

Civilization thereby constructs a synthetic chronological lift across finite lives. Archives, calendars, laws, and inherited structures retain part of the historical count that an isolated individual clock would lose. This resembles the mathematical logic of clock unwrapping, but it is not the universal clock \(T_U\) and does not replace the boundary-selected CMC carrier. It is a local, fallible, socially maintained chronology embedded within universal ordering.

The chain is also neither exact nor unbroken. Records decay, are mistranslated, are destroyed, or become inaccessible. Civilizational continuity is achieved through replication and correction, not through a single immortal internal clock.

5.5 Terminal-neutrality firewall

The terminal condition

\[ E_f\propto I_{\rm records} \]

— shorthand for the factorized form \(E_f = E_{\rm cosmic}\otimes I_R\) of the quantum embedding’s Terminal Record-Neutrality Lemma (Topological Closure and the Two-Clock Quantum Embedding, §5.2), acting as the identity on the record factor — means that the future macroboundary is effectively indifferent among finite local record outcomes. It does not prove that the records are dynamically deleted, that boundary memory is reclaimed, or that only topological winding survives.

The quantity human construction most directly preserves is therefore not an ontological microstate against a deleting universe, but the accessibility of a record to later systems. Schematically, a preservation network attempts to keep

\[ I_{\rm accessible} (R_{\rm past}:R_{\rm future}) >0 \]

for as long as possible, where \(I_{\rm accessible}\) denotes the operationally recoverable mutual information between an earlier record and a later reader. Heat death may drive this accessible information toward zero through thermalization and scrambling without implying fundamental information destruction.

Humanity therefore does not violate terminal neutrality. It constructs temporary artificial boundaries—archives, institutions, redundancy networks, and material structures—that delay the loss of selected record distinctions. The ambition may be permanent remembrance; the physical achievement is an extension of record half-life.

5.6 Interpretive proposition

Constructed-Order Proposition — conditional. If local storage, communication, and error-correction resources admit a closure-capacity description, then living and constructed systems can be modeled as finite positive-margin regimes. They preserve selected record accessibility by raising usable capacity, reducing unresolved uncertainty, and dissipating free energy into their environment.

This proposition does not assign numerical values to \(C\) or \(H\), identify human construction with universal closure, or establish that civilization is a fundamental physical phase. Its value is architectural: it supplies the active branch between universal capacity and the proposed negative-margin exhaust regime.

Status. Thermodynamic dissipation and the role of redundancy in record preservation are standard. Their identification with the STF closure margin is a testable interpretive conjecture requiring an operational local channel.

5.7 Maintenance–Temporality and the universal playground

The constructed-order proposition has a deeper temporal implication. Biological organization is not a stored condition that persists once assembled. It is a continuously renewed process. Membranes, gradients, molecular configurations, error-corrected information, and integrated records remain functional only through ongoing metabolism, repair, replacement, and waste export.

Define a schematic biological maintenance margin

\[ M_B(t) =C_{\rm repair}(t) -H_{\rm degradation}(t), \]

where \(C_{\rm repair}\) is the usable capacity for detecting damage, correcting errors, replacing components, and maintaining record integration, and \(H_{\rm degradation}\) is the unresolved burden generated by thermal noise, mutation, chemical damage, component failure, and environmental disturbance.

Continued integrated organization requires

\[ M_B(t)\ge0. \]

This inequality is not a claim that biology literally runs a Shannon decoder at every level. It states the operational target for a future local capacity model: correction and renewal must keep pace with the distinctions being lost.

Energy dependence of repair

Repair capacity is neither intrinsic nor permanent. It depends on accessible free-energy power, temperature, efficiency, and physical architecture:

\[ C_{\rm repair} =C_{\rm repair} [P_{\rm free},T,\eta,\mathcal A_B]. \]

For the logically irreversible portion of error correction, Landauer’s bound gives the schematic upper rate

\[ C_{\rm repair}^{\rm irr} \lesssim \frac{P_{\rm free}} {k_BT\ln2} \quad\text{bits per unit time}. \]

This does not reduce all biological repair to bit erasure. It makes one limited point exact: irreversible information processing has a nonzero energetic cost, so a finite power supply cannot support an unlimited correction rate.

If accessible power tends toward zero while the degradation burden remains positive, then eventually

\[ C_{\rm repair}<H_{\rm degradation}, \qquad M_B<0. \]

The system can then no longer preserve the integrated boundary and record process constituting that biological clock.

What is and is not inevitable

The second law alone does not derive a particular lifespan for every organism. An imagined system with unlimited free energy, perfect repair, and permanently stable surroundings is not ruled out merely by saying that entropy increases. The stronger result is conditional:

\[ \boxed{ \begin{gathered} H_{\rm degradation}>0,\\ P_{\rm maintenance}>0,\\ P_{\rm free}\ \text{eventually insufficient} \end{gathered} \Longrightarrow \text{finite integrated record persistence}.} \]

Under asymptotic heat-death conditions, usable free-energy gradients vanish. Any local record system requiring nonzero continuous maintenance must therefore lose the capacity to preserve its organization indefinitely. STF does not thereby calculate the timing or biological mechanism of individual death. It locates mortality within a more general distinction: universal ordering can continue after a bounded system loses the capacity to generate its integrated local clock.

The material constituents do not leave universal HAPPENS. They continue to be carried by universal time while no longer sustaining that organism’s local HAPPENS:

\[ \text{integrated biological record clock} \longrightarrow \text{disaggregated matter embedded in }T_U. \]

The universal playground

This gives precise form to the universal-playground analogy.

• Universal HAPPENS is the playground: the globally ordered geometric arena.
• The boundary-selected CMC carrier orders the arena independently of any particular participant.
• Matter remains in the playground whether or not it generates an internal record clock.
• A biological system becomes an active local participant by maintaining a boundary, correcting errors, and producing integrated records.
• Free energy pays for the duration of that participation.
• Death ends the integrated local game, not the playground.
• Externalized records and structures can be inherited by later participants, but they too require maintenance, copying, and interpretation.

The universe supplies the arena, not permanent membership. In compact form:

Universal time is supplied geometrically; lived time is sustained energetically.

Lifetime as a renewal chain

A biological lifetime should therefore not be represented as one static loop. It is a renewal chain of locally maintained processes,

\[ \gamma_{\rm life} =\gamma_1\#\gamma_2\#\cdots\#\gamma_n, \]

spliced by metabolic continuity and record transfer. Each interval inherits enough physical and informational organization from the preceding interval to continue the bounded system. Conception establishes the developing biological process; death is the point beyond which that integrated renewal chain no longer reproduces itself.

Humanity partially externalizes this renewal through intergenerational records, but civilization is also maintenance-dependent. Buildings require repair, software requires compatible interpreters, laws require institutions, archives require copying, and language requires speakers. Civilization is a relay among finite local clocks, not an immortal observer.

Maintenance–Temporality Proposition — conditional. A bounded system whose internal record clock depends upon active repair remains locally integrated only while its maintenance capacity equals or exceeds its degradation burden. If maintenance requires nonzero free-energy flux and accessible free energy eventually becomes insufficient, the system’s integrated local clock is necessarily finite, although its material constituents remain embedded in universal ordering.

Status. The dependence of nonequilibrium biological organization on energy flux and repair is standard. Its expression as an STF closure margin, and the identification of integrated record failure with loss of local HAPPENS, are conditional framework propositions requiring an operational biological model.

5.8 Exergy-limited persistence and the extinction horizon

The energy available to a biological system must be distinguished from the total energy of the surrounding universe. Total energy is not simply “used up.” What biological work depletes is accessible exergy: the portion of an energy distribution capable of driving organized processes before it is degraded into equilibrium heat.

Let

\[ X(t)=\text{accessible exergy stock at time }t. \]

Write the total biological and constructed use rate as

\[ P_{\rm use} =P_{\rm maintenance} +P_{\rm growth} +P_{\rm replication} +P_{\rm infrastructure}. \]

If \(J_{\rm in}(t)\) is newly captured exergy and \(L_X(t)\) represents irreversible loss or resources becoming inaccessible, then

\[ \dot X(t) =J_{\rm in}(t)-P_{\rm use}(t)-L_X(t). \]

The resulting depletion trajectory is

\[ X(t) =X_0 -\int_0^t \left[P_{\rm use}(s)+L_X(s)-J_{\rm in}(s)\right]ds. \]

This equation expresses the two factors required by the proposal: the initial available resource endowment \(X_0\) and the actual use trajectory of the biological or civilizational system. External capture and loss must be included because a living system is not normally a closed fuel tank.

The threshold is power, not merely remaining stock

Survival can fail while \(X(t)>0\) if the remaining stock cannot be converted into usable power quickly enough. Couple the exergy balance to the maintenance margin

\[ M_B(t) =C_{\rm repair}[P_{\rm free}(t),T,\eta,\mathcal A_B] -H_{\rm degradation}(t). \]

Let \(\tau_{\rm buffer}\) be the duration for which stored reserves, dormancy, redundancy, or population structure can tolerate a negative maintenance margin. Define the exergy-driven extinction horizon by

\[ t_{\rm ext} =\inf\left\{ t: M_B(s)<0 \text{ for all } s\in[t,t+\tau_{\rm buffer}] \right\}. \]

This definition does not equate a transient shortage with extinction. It requires repair failure to persist beyond the system’s buffering and recovery capacity.

Equivalently, if \(X_{\rm critical}(t)\) is the stock required to sustain the critical power and accessibility conditions, then the trajectory satisfies

\[ \int_0^{t_{\rm ext}} \left[P_{\rm use}(t)+L_X(t)-J_{\rm in}(t)\right]dt =X_0-X_{\rm critical}(t_{\rm ext}) \]

when the crossing is monotonic and the threshold is reached continuously.

The finite-stock bound

For the simplest closed-stock model,

\[ J_{\rm in}=0, \qquad L_X\ge0, \qquad P_{\rm maintenance}\ge P_{\min}>0, \]

and with no resource substitution or reduction of the minimum maintenance power, the persistence time obeys

\[ t_{\rm ext} \le \frac{X_0-X_{\rm critical}}{P_{\min}}. \]

This is a conditional upper bound, not a universal lifespan formula. It fails if the organism or civilization can drive its required power arbitrarily close to zero, capture new exergy, access previously unavailable stocks, or transform its maintenance architecture.

Population and adaptation

For a biological population or civilization, use rate and maintenance demand depend on population size. A minimal coupled system is

\[ \dot X =J_{\rm in}(X,t) -N(t)p(X,t) -L_X(X,t), \]

\[ \dot N =N(t)\,[b(X,t)-d(X,t)], \]

where \(p\) is per-capita exergy use, and \(b\) and \(d\) are resource-dependent birth and death rates. Extinction occurs when \(N(t)\) falls below a viable reproductive or functional threshold, not automatically when \(X=0\).

This model must allow feedbacks:

• lower population can reduce total use;
• scarcity can change fertility and mortality;
• efficiency can reduce \(p\);
• new technology can change \(J_{\rm in}\) or resource accessibility;
• migration can couple the system to a new stock;
• dormancy can enlarge \(\tau_{\rm buffer}\); and
• infrastructure can increase capture while also adding maintenance demand.

Dividing an initial resource estimate by the present use rate ignores these feedbacks. It gives a constant-rate depletion time, not a robust extinction forecast.

Exergy-Limited Persistence Proposition — conditional. A biological or civilizational system requiring a strictly positive minimum maintenance power cannot persist indefinitely from a finite accessible exergy stock without replenishment. Its exergy-driven extinction horizon is determined by the accumulated difference between exergy use plus irreversible loss and exergy capture, together with the duration for which its repair margin can remain negative without irreversible loss of viability.

This result does not claim that every extinction is energy-driven. Predation, disease, impact, conflict, reproductive failure, or ecological collapse may dominate first. It identifies one calculable limiting mechanism and the variables needed to estimate it.

Status. The exergy balance is standard resource accounting. The finite-stock bound follows under its stated assumptions. Its coupling to STF local HAPPENS and closure capacity remains conditional, while any numerical extinction date requires a specified resource, population, technology, and adaptation model.

6. The Holographic Closure-Capacity Hypothesis

Suppose the following additional premises hold:

1. the terminal boundary algebra has a finite effective state capacity bounded by \(S_{\rm dS}\);
2. every independently distinguishable closure writes a physical boundary record;
3. each record consumes a non-reusable entropy increment \(\Delta S_{\rm closure}>0\);
4. the records cannot be reversibly compressed below that increment; and
5. the same boundary degrees of freedom cannot be reused without erasing a closure distinction required by the final history.

Then a cumulative count would satisfy the conditional bound

\[ N_{\rm closure} \le \frac{S_{\rm dS}}{\Delta S_{\rm closure}}. \]

This implication is valid given the premises. The premises are precisely what remain unproved. In particular, no current STF calculation supplies \(\Delta S_{\rm closure}\), and no theorem says that the global history is stored as a list of separately paid records rather than as one correlated boundary state.

The phrase “the cosmic ledger fills” should therefore be treated as a model, not a consequence of holography. A more conservative possibility is that the boundary algebra bounds simultaneous distinguishability while transactions reuse degrees of freedom or are encoded relationally. These alternatives must be decided by the future closure-coding construction.

Holographic Closure-Capacity Hypothesis. If completed STF transactions are represented by irreducible, non-reusable records in a finite terminal boundary algebra, then the horizon entropy bounds the number of mutually distinguishable closure records.

Status. Conditional proposition. Applicability to the universe is open.

7. Transactional exhaust

7.1 Definition of the hypothesis

Assume a sector requests closure with

\[ C_{\rm closure}<H_{\rm unresolved}. \]

The capacity conjecture labels the history unresolved, but it does not say what happens dynamically. The Transactional Exhaust Hypothesis adds a new premise: the non-closing sector loses access to ordinary record-forming interactions while retaining a covariantly conserved gravitational source.

Symbolically, let \(X\) denote the proposed residue. A consistent effective description requires

\[ S_X=\int d^4x\sqrt{-g}\,\mathcal L_X, \qquad T^{(X)}_{\mu\nu} =-\frac{2}{\sqrt{-g}} \frac{\delta S_X}{\delta g^{\mu\nu}}, \]

and, in the absence of a specified exchange with other sectors,

\[ \nabla_\mu T_{(X)}^{\mu\nu}=0. \]

No such action or transfer law follows merely from the inequality \(C<H\).

7.2 Why gravitational persistence is nontrivial

Saying that a failed transaction “continues to curve spacetime” assumes that its stress-energy survives the failure. A genuine theory must explain:

• which variables persist;
• why their energy is positive and conserved;
• whether the failed sector exchanges energy with the active sector;
• how it couples to the universal CMC carrier;
• whether it is local, nonlocal, or boundary-supported; and
• whether it introduces ghosts, gradient instabilities, or acausal modes.

The distinction between participation in universal geometry and participation in local record formation may motivate weak nongravitational coupling. It does not calculate the stress tensor.

7.3 Cold-dark-matter requirements

To reproduce the background kinematics of pressureless matter, the residue must approximately satisfy

\[ p_X\simeq0, \qquad w_X=\frac{p_X}{\rho_X}\simeq0, \qquad \rho_X\propto a^{-3}. \]

To reproduce perturbative cold dark matter, it must additionally have

\[ c_{s,X}^2\simeq0, \qquad \pi_X\simeq0, \]

over the cosmologically relevant scales, where \(c_s^2\) is the effective sound speed and \(\pi_X\) the anisotropic stress. It must generate the observed growth of structure, lensing potentials, matter power spectrum, halo abundances, and cosmic microwave background effects.

“Non-interacting and gravitational” is therefore only a qualitative resemblance to dark matter, not a derivation of it.

8. Relation to the existing STF scalar dark-matter sector

The STF framework already contains an ultralight oscillating scalar with

\[ m_s\simeq3.94\times10^{-23}\ {\rm eV}/c^2, \qquad \langle w_\phi\rangle\simeq0, \]

as a dark-matter candidate. Transactional exhaust cannot be added without deciding among three mutually distinct possibilities:

1. Identity: the oscillating scalar is the exhaust sector, and closure failure must be shown to produce its mass, phase-space distribution, and stress tensor.
2. Conversion: active STF configurations transfer energy into an exhaust component according to a covariant source term \(Q^\nu\), with \(\nabla_\mu T_\phi^{\mu\nu}=-Q^\nu\) and \(\nabla_\mu T_X^{\mu\nu}=Q^\nu\).
3. Independence: the exhaust is a second dark component with its own abundance and observational constraints.

Without this choice, the framework risks double-counting the dark matter density. Identity is the most economical option but also the most demanding: the closure mechanism would have to recover the known oscillatory scalar dynamics rather than merely relabel it.

The ultralight mass also means that the scalar is not automatically identical to ideal cold dark matter on every scale. Its gradient or wave pressure must be included when comparing the hypothesis with structure formation. The exhaust proposal cannot erase those existing obligations.

Caveat on option 3 and the Lyman-α closure (carried from the V1.0 review, August 2026). The B10 calculation has closed the scalar’s all-dark-matter reading at \(m_s\): the Lyman-α bound excludes \(f=1\) by a factor of about 508 (see the Dark Matter paper, §VI.B). Option 3 must not be invoked to evade that closure. A subdominant scalar fraction \(f<1\) was always available by matching a smaller amplitude — no exhaust conjecture is required to obtain it — and what the exhaust would then supply, the remaining dark density, has no derived abundance, equation of state, or sound speed. A partition adopted because it evades a bound is not a partition derived, and would trip this paper’s own falsifier 6 (double counting without a derived partition). The connection is recorded here so that it is available if a partition is ever derived, and unusable as a shortcut in the meantime.

Status. No identity or conversion theorem presently exists.

9. Cosmological limits and prohibited shortcuts

The holographic and exhaust conjectures do not currently derive:

• an asymptotic de Sitter phase;
• a present-day equation of state \(w_0=-1\);
• inflation or its perturbation spectrum;
• a time-dependent dark-energy equation of state;
• a solution of the Hubble-constant tension; or
• the observed dark-matter abundance.

Using the de Sitter entropy formula assumes a de Sitter horizon for the purpose of the bound; it cannot then be cited as an independent derivation that the universe must approach de Sitter. Likewise, a boundary capacity metaphor does not determine a Friedmann equation.

Any cosmological claim requires a closed covariant action, background field equations, perturbation equations, stability conditions, initial data, and a likelihood comparison with cosmological observations.

10. Falsifiers and failure conditions

The conjecture program would fail or require major revision under any of the following results:

1. No closure code: the STF winding sectors cannot be mapped to accessible boundary records while preserving covariance and the established no-signaling conditions.
2. Reusable encoding: closure records can be reversibly encoded or reused without consuming an irreducible entropy increment. Then \(S_{\rm dS}/\Delta S_{\rm closure}\) is not a transaction count.
3. No conserved residue: every covariant completion of \(C<H\) transfers or removes the associated stress-energy rather than leaving a gravitational source.
4. Wrong equation of state: the derived residue has significant pressure, sound speed, or anisotropic stress on scales where dark matter must cluster.
5. Instability: the exhaust action contains ghosts, gradient instabilities, negative energy, or an inconsistent exchange with the CMC carrier.
6. Double counting: the exhaust and oscillating scalar independently account for the same observed dark density without a derived partition.
7. Cosmological exclusion: the component violates CMB, lensing, structure, halo, or expansion-history constraints.
8. No local capacity representation: storage, communication, uncertainty, and error correction in record-forming systems cannot be expressed in one operationally consistent \(C-H\) model. The constructed-order proposition would then remain a metaphor rather than a physical application.

Until an action exists, these are requirements rather than numerical predictions. Their purpose is to prevent the conjecture from becoming immune to physics.

12. Forward derivation program

The work should proceed in dependency order.

1. Define the boundary algebra. Specify the observables that distinguish closure records at the terminal macroboundary.
2. Construct the closure code. Map admissible histories and winding data to those observables and calculate the accessible mutual information.
3. Prove or reject non-reuse. Determine whether closure distinctions consume irreducible boundary capacity or can be encoded reversibly and relationally.
4. Operationalize constructed order. Define matched local measures of record capacity, unresolved information, error correction, free-energy cost, degradation burden, and accessible record lifetime for a tractable biological or technological system. Test whether \(M_B=C_{\rm repair}-H_{\rm degradation}\) predicts a measurable loss of integrated record fidelity.
5. Construct an exergy-extinction model. Freeze one biological or civilizational system, specify \(X_0\), \(J_{\rm in}\), \(P_{\rm use}\), \(L_X\), \(X_{\rm critical}\), \(\tau_{\rm buffer}\), and the demographic feedbacks, then propagate uncertainty to \(t_{\rm ext}\).
6. Derive \(\Delta S_{\rm closure}\). Only after the upstream steps can a transaction-count bound be evaluated.
7. Build the exhaust action. Introduce no phenomenological dark component until a covariant residue or transfer law follows from the failed-closure dynamics.
8. Resolve the scalar relation. Prove identity, conversion, or independence relative to the \(m_s\) oscillating scalar.
9. Perform stability and perturbation tests. Derive background and linear cosmological equations before numerical parameter fitting.
10. Confront observations. Test CMB, large-scale structure, lensing, halo, and expansion data with a frozen likelihood pipeline.

A negative result at any upstream step is informative. In particular, failure of the non-reuse premise would reject the finite-ledger picture while leaving the broader Closure-Capacity Correspondence available in a rate-based form.

13. Conclusion

Holography offers STF a finite state-counting scale, not a ready-made cosmic transaction counter. Topological closure offers a normalized winding class, not a Shannon channel or thermodynamic write cost. The data-rate theorem offers a structural model of stabilization, not a proof that the universe implements the corresponding encoder and decoder. The value of the present proposal lies in placing these ingredients in a single dependency graph without identifying them prematurely.

The Holographic Closure-Capacity Hypothesis becomes meaningful if completed transactions occupy distinguishable, non-reusable records in a finite terminal boundary algebra. The Transactional Exhaust Hypothesis becomes physical if failure of that capacity condition produces a covariantly conserved residue with a derived effective action. Only after both steps can the framework ask whether the residue behaves as dark matter.

Between those two limits lies the world of living and constructed order. Organisms and civilizations preserve records by increasing redundancy, communication, storage, and error correction while using languages, institutions, and standards to reduce unresolved uncertainty. They do not escape terminal neutrality or reverse the second law. They spend free-energy gradients and export entropy to keep particular histories accessible across finite local clocks. Civilization is thus neither a permanent exception to the cosmic landscape nor merely passive matter within it. It is a distributed, fallible architecture for extending how long portions of that landscape can remain readable to later observers.

The same dependence makes biological and civilizational clocks intrinsically temporal. Their persistence is continuously purchased through metabolism, repair, copying, and interpretation. When maintenance capacity can no longer match degradation, the integrated local clock ends while its constituents remain carried by universal ordering. The universal-playground analogy states the relationship directly: global geometry supplies the arena; free energy supports finite participation; inherited records allow later players to resume parts of earlier games. Universal time is supplied geometrically, while lived time is sustained energetically.

That finite participation can be represented quantitatively by an exergy trajectory. Initial accessible resources set the stock; capture, use, and loss determine its evolution; repair thresholds and buffering determine when depletion becomes irreversible loss of viability. A constant-rate division is only the first limiting case. A defensible extinction horizon requires the coupled dynamics of resources, population, technology, adaptation, and minimum maintenance power. The framework thereby acquires a calculable route from finite resources to finite biological persistence without confusing exergy depletion with destruction of total energy.

The “cosmic ledger” and “garbage collection” metaphors may guide intuition, but the theory must ultimately replace them with a code, a channel, a boundary algebra, and a stress tensor. Until then, transactional exhaust is a speculative extension of STF—clearly motivated, sharply constrained, and deliberately not presented as a theorem.
