<p>Path-centric governance, decision closure, structural suppression of hallucinations, C/E/U regimes, decoupling depth from decision cost.</p>

<p>QCO-NN operates as a cybernetic decision engine, not a traditional layered neural network.</p>

<p>It governs computation via paths (Π) rather than fixed edges or layers, using a hierarchical QCO-norm to weight deeper abstractions exponentially less.</p>

<li>C/E/U regimes — trichotomy of outcomes: Closure (C), Exploratory-admissible (E), Undecidable (U)</li>
<li>Structural hallucination suppression — no forced token continuation; output is the moment of stabilization or explicit undecidability</li>
<li>Decoupling depth from cost — arbitrary structural depth is possible (via loops and CD tower with adaptive K), but effective decision cost remains adaptive and bounded by active components under the norm;</li>

<p>ENGINEERING NOTE: Representation-Induced Behavior</p>

<p>This implementation intentionally relies on properties of IEEE-754 floating-point arithmetic as a computational substrate.</p>

<p>Key points for implementers:</p>

<ul>
<li>The algorithm does NOT assume exact arithmetic over <span class="math">\mathbb R</span>.</li>
<li>Floating-point rounding, exponent scaling, and mantissa truncation are treated as deterministic projection operators.</li>
<li>Observed attractors and quasi-stable states arise from the global geometry of the floating-point lattice, not from numerical noise.</li>
<li>Behavior is stable across rounding modes and precision reductions, indicating representation-level invariance rather than implementation artifacts.</li>
</ul>

<p>From an engineering perspective:</p>

<ul>
<li>This is expected behavior.</li>
<li>This is reproducible behavior.</li>
<li>This is architecture-consistent behavior.</li>
</ul>

<p>Attempts to "fix" these effects by enforcing real-number identities (associativity, exact cancellation, symbolic reordering) will destroy the intended dynamics of the system.</p>

<p>This code operates in a representation-induced projective algebra, not in an ideal real-number field.</p>]]></content:encoded>

<h2 id="zero-divisors-in-sedonion-algebra-under-floating-point-arithmetic">Zero Divisors in Sedonion Algebra under Floating-Point Arithmetic</h2>

<p>In exact Cayley–Dickson algebras over <span class="math">\mathbb R</span>, zero divisors are well-defined, algebraically stable objects: nonzero elements whose product vanishes exactly.</p>

<p>This property relies on exact equality between multiple coupled components across dimensions.</p>

<p>When the same algebra is implemented using IEEE-754 floating-point arithmetic, this stability is lost.</p>

<h2 id="reason">Reason</h2>

<p>Each multiplication step (sedonion → octonion → quaternion) introduces:</p>

<ul>
<li>multiple floating-point multiplications,</li>
<li>multiple floating-point additions and subtractions,</li>
<li>independent rounding at each operation.</li>
</ul>

<p>As a result, algebraic equalities required for exact zero divisors are replaced by inequalities of the form:</p>

<div class="math">
| \text{component} | &lt; \varepsilon
</div>


<p>where <span class="math">\varepsilon</span> is the machine epsilon at the working scale.</p>

<p>Crucially, <span class="math">\varepsilon</span> is not a neutral approximation error but a structural element of the numerical algebra.</p>

<h2 id="consequence">Consequence</h2>

<p>Zero divisors no longer behave as fixed algebraic points. Instead, they become dynamic numerical structures that:</p>

<ul>
<li>drift toward zero under some rounding histories,</li>
<li>are repelled from zero under others,</li>
<li>may cross below epsilon (numerical annihilation), or remain finite depending on accumulated perturbations.</li>
</ul>

<p>Thus, in floating-point arithmetic zero divisors are not static objects, but evolving orbits under projection.</p>

<h2 id="practical-implication">Practical Implication</h2>

<p>Repeated quaternion (or higher CD) multiplications do not converge to exact zero even when the corresponding real-algebra product would.</p>

<p>This behavior is not a bug, noise, or instability. It is a direct consequence of treating floating-point arithmetic as a first-class algebra rather than an approximation of <span class="math">\mathbb R</span>.</p>

<p>The observed "non-zero residue" is an invariant of the projection history, not a violation of the algebraic construction.</p>]]></content:encoded>

<p>Crawling of zero divisors in sedonions leading to NaN</p>

<ul class="toc">
<li class="toc1"><a href="/papers/crawling-of-zero-divisors-in-sedonions-leading-to-nan#this-behavior-is-expected">1. This behavior is expected.</a></li>
<li class="toc1"><a href="/papers/crawling-of-zero-divisors-in-sedonions-leading-to-nan#key-points">2. Key points:</a></li>
</ul>

<h2 id="this-behavior-is-expected">This behavior is expected.</h2>

<p>The implementation operates on a 16D Cayley–Dickson algebra (sedonions), which is non-alternative, non-normed, and contains non-trivial zero divisors. The arithmetic is performed using IEEE-754 floating-point numbers, i.e. a finite-precision projection of the underlying real algebra.</p>

<h2 id="key-points">Key points:</h2>

<ol>
<li><p>Zero divisors are not isolated points.
In sedonions, zero divisors form extended manifolds rather than single algebraic elements. When projected onto finite-precision floats, these manifolds become <span class="math">\varepsilon</span>-thick regions instead of exact null sets.</p></li>
<li><p>Deterministic drift under iteration.
The system is fully deterministic. Apparent randomness arises from sensitivity to rounding and cancellation in IEEE-754 arithmetic, not from stochastic input. Small perturbations caused by rounding errors result in systematic drift of zero-divisor components between coordinates.</p></li>
<li><p>"Crawling" is a structural effect, not instability.
Under repeated nonlinear mixing (e.g. sedonion → octonion → quaternion projections), zero-divisor states do not remain fixed but migrate across components. This crawling behavior is a natural consequence of iterating a non-normed algebra on a discrete numerical lattice.</p></li>
<li><p>NaN is a boundary marker, not a bug.
NaN values arise when trajectories intersect algebraic singularities amplified by finite-precision projection (e.g. <span class="math">\infty - \infty</span>, <span class="math">0 \cdot \infty</span>). In this context, NaN acts as an absorbing boundary condition in the IEEE-754 state space, not as an implementation error.</p></li>
<li><p>No physical randomness is involved.
The computation is entirely deterministic. The observed loss of reproducibility at the real-number level is due to the impossibility of "hitting the same point" exactly in a discretized algebra with zero divisors.</p></li>
</ol>

<p>In summary, this code does not approximate real-valued sedonions; it defines a deterministic dynamical system on the IEEE-754 projection of a zero-divisor algebra. The crawling of zero divisors and occasional collapse into NaN are intrinsic and expected properties of this system.</p>]]></content:encoded>

<h2 id="overview">Overview</h2>

<p>This code defines a deterministic numerical transformation producing a scale-dependent, highly stable floating-point invariant ("fraction"), computed as a ratio of two structured sums involving fractional powers.</p>

<p>The construction is intentionally simple, but it exhibits a nontrivial and repeatable behavior when evaluated in finite-precision arithmetic (IEEE-754 floating point), which is <em>qualitatively different</em> from it's behavior in the real numbers <span class="math">\mathbb R</span>.</p>

<p>The goal of this code is <strong>not cryptography</strong>, but the exploration of numerical structure arising from:</p>

<ul>
<li>finite mantissa resolution,</li>
<li>deterministic rounding,</li>
<li>irreversible projection from <span class="math">\mathbb R</span> to a discrete numeric algebra.</li>
</ul>

<p>This makes it suitable as:
- a numerical stability probe,
- a scale-sensitive fingerprint,
- a didactic example of projection-induced structure.</p>

<h2 id="definition">Definition</h2>

<p>For a given integer key <span class="math">k</span> and a finite number of rounds <span class="math">N</span>:</p>

<p>Left side:</p>

<div class="math">
L (k) = k + \sum k^{\frac{1}{p}}
</div>


<p>for <span class="math">p</span> in even-indexed primes</p>

<p>Right side:</p>

<div class="math">
R (k) = \sqrt{k} + \sum k^{\frac{1}{p}}
</div>


<p>for <span class="math">p</span> in odd-indexed primes</p>

<p>The resulting fraction is:</p>

<div class="math">
F (k) = \dfrac{L(k)}{R(k)}
</div>


<p>The sums are truncated after <span class="math">N</span> terms.</p>

<h2 id="behavior-in-math-mathbb-r-idealized-analysis">Behavior in <span class="math">\mathbb R</span> (Idealized Analysis)</h2>

<p>In exact real arithmetic:</p>

<ul>
<li>Both sums diverge slowly and monotonically.</li>
<li>The dominant terms cancel asymptotically.</li>
<li>The ratio <span class="math">F(k) \to 1</span> as <span class="math">N \to \infty</span>.</li>
</ul>

<p>This convergence does not require analytic number theory or zeta-function machinery; any balanced construction with symmetric fractional powers will exhibit similar asymptotic behavior.</p>

<p>In <span class="math">\mathbb R</span>, the limit exists and is trivial.</p>

<h2 id="behavior-in-ieee-754-floating-point">Behavior in IEEE-754 Floating Point</h2>

<p>In finite-precision arithmetic, the behavior changes qualitatively:</p>

<ol>
<li>The ratio does <strong>not</strong> converge to <span class="math">1</span>.</li>
<li>After a sufficient number of rounds (typically ~1024–2048), <span class="math">F(k)</span> stabilizes at a <strong>finite</strong>, <strong>key-dependent value</strong>.</li>
<li>Further iterations no longer change the result (numerical convergence).</li>
</ol>

<p>This stabilized value is a <strong>quasi-attractor</strong> induced by projection onto the floating-point lattice.</p>

<p>Key empirical properties:</p>

<ul>
<li>Strong dependence on key magnitude (scale).</li>
<li>Weak dependence on rounding mode.</li>
<li>High reproducibility across runs.</li>
</ul>

<h2 id="rounding-mode-independence">Rounding-Mode Independence</h2>

<p>Changing IEEE-754 rounding modes:
- round-to-nearest-even,
- toward zero,
- toward <span class="math">+ \infty</span>,
- toward <span class="math">- \infty</span>,</p>

<p>affects the final value only at the level of <span class="math">\approx 1\text{e-}5</span> to <span class="math">\approx 1\text{e-} 3</span> relative error, even after thousands of iterations.</p>

<p>This indicates that:</p>

<ul>
<li>the structure is <em>not</em> rounding noise,</li>
<li>the attractor is determined by the <strong>global geometry of the float lattice</strong>,</li>
<li>local rounding differences average out under iteration.</li>
</ul>

<h2 id="role-of-mantissa-size">Role of Mantissa Size</h2>

<p>Two independent mantissas are relevant:</p>

<ol>
<li>Mantissa of the <strong>key representation</strong>.</li>
<li>Mantissa of the <strong>floating-point arithmetic</strong>.</li>
</ol>

<p>Important regimes:</p>

<ul>
<li>If the key mantissa is comparable to or larger than the FPU mantissa, nearby integer keys produce distinct fractions.</li>
<li>If the FPU mantissa significantly exceeds the key mantissa, distinct keys can collapse onto the same fraction (true numerical collisions).</li>
</ul>

<p>Thus, collision behavior is not mysterious -- it is a direct consequence of projection from a higher-resolution space into a lower-resolution one.</p>

<h2 id="why-so-many-iterations">Why So Many Iterations?</h2>

<p>Iterations serve to:</p>

<ul>
<li>drive the computation beyond the local influence of initial rounding,</li>
<li>allow projection effects to accumulate,</li>
<li>reach the stable orbit of the numerical system.</li>
</ul>

<p>The required iteration count scales with mantissa size and key magnitude. Stopping earlier yields transient values, not the attractor.</p>

<h2 id="geometric-intuition">Geometric Intuition</h2>

<p>Geometrically, the construction can be viewed as:</p>

<ul>
<li>two slowly tightening logarithmic spirals in <span class="math">\mathbb R</span>,</li>
<li>whose ratio tends to <span class="math">1</span> in the continuous limit,</li>
<li>but whose discrete projections land on a stable orbit in floating-point space.</li>
</ul>

<p>The attractor is not a fixed point in <span class="math">\mathbb R</span>, but a fixed <strong>orbit under projection</strong>.</p>

<h2 id="what-this-is-not">What This Is NOT</h2>

<p>This function does NOT claim:</p>

<ul>
<li>cryptographic collision resistance,</li>
<li>uniform randomness,</li>
<li>security under adversarial models,</li>
<li>independence from machine architecture.</li>
</ul>

<p>It should not be labeled or marketed as encryption.</p>

<h2 id="what-this-is">What This IS</h2>

<p>This is:</p>

<ul>
<li>a deterministic numerical transformation,</li>
<li>operating in a non-field algebra with:

<ul>
<li>finite resolution,</li>
<li><span class="math">NaN</span> and <span class="math">\pm \infty</span>,</li>
<li>non-invertibility,</li>
</ul></li>
<li>exhibiting stable, scale-sensitive structure.</li>
</ul>

<p>The observed behavior arises from the algebra itself, not from implementation bugs or randomness.</p>

<h2 id="interpretation">Interpretation</h2>

<p>In <span class="math">\mathbb R</span>, the limit exists and is trivial. In floating-point arithmetic, the limit is replaced by a stable projection.</p>

<p>This illustrates a general principle:</p>

<pre><code>Deterministic + finite resolution + projection
⇒ apparent irreversibility without randomness.
</code></pre>

<h2 id="intended-use">Intended Use</h2>

<ul>
<li>Numerical experiments.</li>
<li>Studying projection-induced invariants.</li>
<li>Exploring alternative algebraic intuitions.</li>
<li>Educational demonstrations of finite-precision effects.</li>
</ul>

<h2 id="final-note">Final Note</h2>

<p>This code treats floating-point arithmetic as a <strong>first-class algebraic structure</strong>, not as a flawed approximation of <span class="math">\mathbb R</span>.</p>

<p>If one insists on interpreting it through the lens of ideal real analysis, the behavior appears anomalous.</p>

<p>If one accepts the algebra actually being used, the behavior is expected.</p>]]></content:encoded>

<content:encoded><![CDATA[<p>Author: Jack Kowalski <code>&lt;jack@entropment.com&gt;</code></p>

<p>This code deliberately treats floating-point behavior (IEEE-754) as a <em>primary algebraic structure</em>, not as an approximation of <span class="math">\mathbb R</span>.</p>

<p>Key design stance:</p>

<ol>
<li><p>IEEE-754 arithmetic is NOT assumed to be an implementation of the real numbers <span class="math">\mathbb R</span>. It is treated as a discrete, projective numerical space with:</p>

<ul>
<li>minimal scale <span class="math">\varepsilon</span> (machine epsilon),</li>
<li>non-numeric states (NaN, <span class="math">\pm \infty</span>),</li>
<li>path-dependent evaluation (ordering matters),</li>
<li>loss of global associativity and distributivity.</li>
</ul></li>
<li><p>From this perspective, deviations from <span class="math">\mathbb R</span> are NOT "errors". They are structural properties of the underlying numerical space.</p></li>
<li><p>Zero divisors and near-zero states are treated as <em>dynamical objects</em>, not algebraic defects. Under iteration, they may:</p>

<ul>
<li>persist,</li>
<li>drift ("crawl") across rounds,</li>
<li>fall below <span class="math">\varepsilon</span> and collapse to <span class="math">0</span>,</li>
<li>or escape to NaN,</li>
</ul>

<p>depending on the number and coupling of perturbed floating-point operations.</p></li>
<li><p>Over <span class="math">\mathbb R</span>, the corresponding algebra (e.g. CD algebras, sedenions) exhibits fixed zero-divisor structure. Over IEEE-754, this structure becomes a <em>pseudo-orbit</em>:</p>

<ul>
<li>deterministic,</li>
<li>architecture-consistent,</li>
<li>but no longer stationary.</li>
</ul></li>
<li><p>This behavior is EXPECTED and intentional. It arises from projecting a continuous algebra with zero divisors onto a discrete numerical lattice with finite mantissa.</p></li>
<li><p>The resulting dynamics are:</p>

<ul>
<li>deterministic (no randomness involved),</li>
<li>highly stable with respect to rounding modes,</li>
<li>sensitive to global scale (mantissa/exponent geometry),</li>
<li>and unsuitable for interpretation within classical <span class="math">\mathbb R</span>-based algebra.</li>
</ul></li>
</ol>

<p>This code therefore operates in a different ontological regime: not "real-number algebra with errors", but "projected algebra with intrinsic numerical dynamics".</p>]]></content:encoded>
