Conscious Window

Abstract

Six results (T-123 — T-127, C27) closing five critical operationalization problems: uniqueness of representation for digital agents, non-emptiness of the full viability region, canonicity of the reflection measure, and attractor stability with basin of attraction.

---

§1. G₂-uniqueness of representation (T-123)

Formulation [T]

For any system satisfying axioms A1–A5, the holonomic representation $G: \mathrm{States} \to \mathcal{D}(\mathbb{C}^7)$ is unique up to $G_2 = \mathrm{Aut}(\mathbb{O})$ kinematically and — once the axiomatic dynamics pins the functional frame — up to the finite frame group $\Gamma_{\!\text{oct}}$ (frame decision D-0910). The diagonal elements $\gamma_{kk}$ are determined uniquely (up to a relabelling of axes) as projections onto the 7 functionally unique dimensions.

Proof

Direct consequence of three proven theorems:

1. T-42a [T] (G₂-rigidity): The holonomic representation $G$ is unique up to $G_2$. Any two representations $G_1, G_2$ are related by a unitary transformation $U \in G_2$: $G_2(\cdot) = U \cdot G_1(\cdot) \cdot U^\dagger$.

2. T-40f [T] (Full minimality 7/7): Each of the 7 dimensions [A, S, D, L, E, O, U] is functionally necessary — removing any one leads to loss of viability or violation of an axiom.

3. T-15, [T] (Bridge closure): $(AP) + (PH) + (QG) + (V) \Longrightarrow P1 + P2$ — the autopoietic and physical premises entail the octonionic structure $\mathbb{O}$ and $G_2$-symmetry, with the canonical orientation of the Fano lines (T15-canon; registry row 41n; cited as [C at (Alt)] earlier on 2026-09-25).

From T-42a: the representation is unique up to $G_2$. From T-40f: projections onto 7 dimensions form the unique functionally complete basis. From T-15: the $G_2$ structure is derived from the axioms, not postulated; T-123 is accordingly [T] as a consequence of the axioms (registry row T-123; the intermediate "[T] given the octonionic structure, [C at (Alt)] as a consequence of the axioms" is superseded by T15-canon). $\blacksquare$

Consequence for digital agents

The anchor map $\pi: \mathcal{H}_{\mathrm{hidden}} \to \mathcal{D}(\mathbb{C}^7)$, covariant with respect to $\mathcal{L}_\Omega$, is unique up to the finite frame group $\Gamma_{\!\text{oct}}$ (in particular up to $G_2$). The semantics of $\gamma_{kk}$ is not arbitrary — it is determined by axioms A1–A5. This closes the problem of encoding arbitrariness for digital agents.

§2. Conscious window — non-emptiness of V_full (T-124)

Formulation [T]

The full viability set

$$\mathcal{V}_{\mathrm{full}} = \left\{\Gamma \in \mathcal{D}(\mathbb{C}^7) : P \in \left(\tfrac{2}{7}, \tfrac{3}{7}\right] \;\land\; \Phi \geq 1 \;\land\; \forall k: \sigma_k < 1\right\}$$

is non-empty.

Proof (constructive)

Step 1. Consider the family $\Gamma_\lambda = (1-\lambda)\,I/7 + \lambda\,|\psi\rangle\langle\psi|$, where $|\psi\rangle = \frac{1}{\sqrt{7}}\sum_{k=0}^{6}|k\rangle$ is an equal-amplitude vector.

Spectrum: one eigenvalue $\frac{1+6\lambda}{7}$ (multiplicity 1) and six eigenvalues $\frac{1-\lambda}{7}$ (multiplicity 6). From this:

$$P(\Gamma_\lambda) = \frac{1}{7} + \frac{6\lambda^2}{7}, \quad R = \frac{1}{7P} = \frac{1}{1 + 6\lambda^2}, \quad \Phi(\Gamma_\lambda) = 6\lambda^2$$

Step 2. For $\lambda \in (1/\sqrt{6},\; 1/\sqrt{3}]$:

Indicator	Value	Condition
$P$	$(2/7, 3/7]$	$\checkmark$
$R$	$[1/3, 1/2]$	$\geq 1/3\;\checkmark$
$\Phi$	$[1, 2]$	$\geq 1\;\checkmark$

Boundary values: at $\lambda = 1/\sqrt{6}$ we get $R = 1/2$ (inclusive), at $\lambda = 1/\sqrt{3}$ — $R = 1/3$ (inclusive).

Step 3 (σ-condition). By canonical definition (T-92 [T]):

$\sigma_k = \mathrm{clamp}(1 - 7\gamma_{kk},\; 0,\; 1)$

For equal-amplitude $\Gamma_\lambda$ all diagonal elements equal $\gamma_{kk} = 1/7$ for all $k$ (since $|\psi\rangle = \frac{1}{\sqrt{7}}\sum_k|k\rangle$ is an equal-amplitude vector). Therefore:

$\sigma_k = \mathrm{clamp}(1 - 7 \cdot \tfrac{1}{7},\; 0,\; 1) = \mathrm{clamp}(0,\; 0,\; 1) = 0 < 1 \quad \forall k$

All $\sigma$-conditions ($\sigma_k < 1$) are satisfied without any perturbation.

Step 4 ($D_{\mathrm{diff}}$). Eigenvalues of $\Gamma_\lambda$: $\{(1+6\lambda)/7\; (\times 1),\; (1-\lambda)/7\; (\times 6)\}$. For $\lambda \in (1/\sqrt{6}, 1/\sqrt{3}]$: two distinct eigenvalues, $\mathrm{rank}(\Gamma_\lambda) = 7$.

Von Neumann entropy: $S_{vN} = -\frac{1+6\lambda}{7}\ln\frac{1+6\lambda}{7} - \frac{6(1-\lambda)}{7}\ln\frac{1-\lambda}{7}$.

At $\lambda = 1/\sqrt{6} \approx 0.408$: eigenvalues $\approx 0.493$ (×1) and $\approx 0.085$ (×6), $S_{vN} \approx 1.60$, $D_{\mathrm{diff}} = e^{S_{vN}} \approx 4.96$. $S_{vN}$ decreases in $\lambda$ (the top eigenvalue grows), so the minimum over the interval is at $\lambda = 1/\sqrt{3}$: eigenvalues $\approx 0.638$ and $\approx 0.060$, $S_{vN} \approx 1.30$, $D_{\mathrm{diff}} \approx 3.68 \geq 2$. The condition $D_{\mathrm{diff}} \geq 2$ holds over the entire interval. (Corrected 2026-09-25: the step printed the top eigenvalue at $\lambda = 1/\sqrt6$ as $0.572$ and put the minimum at $\lambda \to 1/\sqrt3$ with both eigenvalues tending to $1/7$ and $D_{\mathrm{diff}} \to 7$; the conclusion was right, the numbers were not.)

Therefore, $\Gamma_\lambda \in \mathcal{V}_{\mathrm{full}}$ for any $\lambda \in (1/\sqrt{6}, 1/\sqrt{3}]$, and the set is non-empty. $\blacksquare$

The witness is an attractor [T]. With the collineation-anchored self-model $\varphi_J(\Gamma) = k\mathcal{P}_\alpha(\Gamma) + R\,|\psi\rangle\langle\psi|$ — the anchor is this same $|\psi\rangle$ — an isolated holon at $H = 0$ and $\kappa > \kappa_c(\alpha)$ ($16.63$ at $\alpha = 0$, $29.25$ at $\alpha = 1/2$) has exactly one living attractor, and it is $\Gamma_\lambda$ with $\lambda \in (0.42, 1/2)$: a hyperbolic sink inside $\mathcal{V}_{\mathrm{full}}$, persisting for small $H$ (living attractor in the window). The anchor is not an extra choice of this proof: $\varphi_J$ is derived, up to the phase gauge of the $H$-free dynamics, from the single principle (Eq-V) — the self-model privileges no axis of the frame and is the most viable such (T-334 [T]; the principle itself is [Pr]). The sink survives rephasing of $|\psi\rangle$, small non-symmetric parts of the anchor and frame detunings up to an explicit bound (T-335 [T]); the required $\kappa$ is within a factor $1.41$ of the floor that every self-model of this form needs (T-336 [T]).

Numerical verification of the conscious window (SYNARC)

Attractor of the embodied agent: $P = 0.4286 \approx 3/7$ — at the upper boundary of the Goldilocks zone $[2/7, 3/7]$. Stability radius $r_{\mathrm{stab}} = \sqrt{3/7 - 2/7} \approx 0.378$. After an impulse perturbation $\|h\| < r^2_{\mathrm{stab}}$: recovery in $\tau_{\mathrm{recovery}} \approx 0$ ticks (instantaneous attraction). Exponential convergence (T-125) confirmed with $R^2 > 0.9$.

Corollary (Goldilocks zone)

$$P \in \left(\frac{2}{7}, \frac{3}{7}\right] \text{ — Goldilocks zone for consciousness}$$

• $P < 2/7$: system is not viable ($\sigma_A = 1$)
• $P > 3/7$: $R = 1/(7P) < 1/3$ — insufficient reflection for L2

note

Cosmological realization of the $3/7$ attractor [C]

T-266 applies this attractor to the Universe-holon: its terminal stage sits at this same upper edge $P = 3/7$, and the present-day stage lies at a fractional distance $\tfrac{3H_0}{2\kappa}(1+w_0) \sim 10^{-60}$ from it — so, conditional on the Universe-as-viable-holon reading (H1.1), the cosmos is at the Goldilocks attractor to $\sim 59$ figures, with the DESI dark-energy drift as the $\kappa/H_0$-amplified residual. The $3/7$ edge is thus not only the fixed point of embodied conscious agents but the terminal configuration of the Universe itself.

Corollary — voice-multiplicity in the window

Every state of $\mathcal{V}_{\mathrm{full}}$ is spread across at least $14/3 \approx 4.67$ of its seven voices [T]. Since $P = \sum_k \gamma_{kk}^2 + \sum_{i\neq j}|\gamma_{ij}|^2$ and $\Phi = \big(\sum_{i\neq j}|\gamma_{ij}|^2\big)\big/\sum_k \gamma_{kk}^2$, one has the exact identity $\sum_k \gamma_{kk}^2 = P/(1+\Phi)$, hence the diagonal participation

$$\frac{1}{\sum_k \gamma_{kk}^2} = \frac{1+\Phi}{P} \;\geq\; \frac{2}{3/7} = \frac{14}{3} \approx 4.67,$$

using $\Phi \geq 1$ and $P \leq 3/7$ (the window). Consciousness is therefore structurally broad — never localised on a single voice. This is a diagonal statement, distinct from the eigenvalue differentiation $D_{\mathrm{diff}} = e^{S_{vN}} \geq 2$ of Step 4: a state may satisfy one and fail the other (see the Φ characterisation in dimension U). For the constructed family $\Gamma_\lambda$ the diagonal is uniform, $\gamma_{kk} = 1/7$, so its participation is exactly $(1+\Phi)/P = 7$ — the maximum, all seven voices at once.

§3. Local asymptotic stability of attractor (T-125)

Formulation [T]

When $P(\rho^*_\Omega) > 2/7$ the attractor $\rho^*_\Omega$ is locally asymptotically stable: there exists a neighborhood $U(\rho^*_\Omega) \subset \mathcal{V}_P$ such that for all $\Gamma(0) \in U$:

$$\|\Gamma(\tau) - \rho^*_\Omega\|_F \leq \|\Gamma(0) - \rho^*_\Omega\|_F \cdot e^{-c\tau}, \quad c > 0$$

Proof

Step 1 (Lyapunov function). Define $V(\Gamma) = \|\Gamma - \rho^*_\Omega\|^2_F$.

Step 2 (Jacobian). The Jacobian $J = d\mathcal{L}_\Omega/d\Gamma|_{\rho^*_\Omega}$ is a linear operator on the tangent space $T_{\rho^*_\Omega}\mathcal{D}(\mathbb{C}^7)$ (Hermitian traceless matrices). It is smooth when $P(\rho^*_\Omega) > 2/7$, since the gate $g_V(P)$ and the regeneration function are differentiable inside $\mathcal{V}_P$.

Step 3 (Spectrum). $\mathrm{Re}(\lambda_k) < 0$ for all eigenvalues of $J$ on the tangent space. This follows from two sources of contractivity:

• Linear part $\mathcal{L}_0$: spectral gap $\lambda_{\mathrm{gap}} > 0$ from primitivity T-39a [T].
• Regeneration $\mathcal{R}$: adds contractivity $\kappa(\rho^*_\Omega) \cdot g_V(P(\rho^*_\Omega)) > 0$, since $P > 2/7 \Rightarrow g_V > 0$.

Total contractivity: $c \geq \min(\lambda_{\mathrm{gap}},\; \kappa \cdot g_V) > 0$.

Step 4 (Lyapunov theorem). Standard linear stability theorem: $\mathrm{Re}(\lambda_k) < 0$ for all $k$ $\Rightarrow$ $\exists U$ neighborhood of $\rho^*_\Omega$ with exponential convergence at rate $c$.

Step 5 (Radius). Neighborhood $U = B(\rho^*_\Omega, r_{\mathrm{stab}}/2)$, where $r_{\mathrm{stab}}$ from T-104 [T]. $\blacksquare$

Dynamical reading of the threshold: the basin boundary

The threshold $P_{\mathrm{crit}} = 2/7$ enters T-124 as a static inequality. The canonical flow gives it a second, dynamical face [С]: in the bistable regime (a grey attractor beside a living one) the boundary between the two basins converges to exactly $2/7$ in the fast-clock limit. Measured on the canonical tick with a continuous family of starting mixtures (the self-model grid would censor the answer at its own quantum): at $\omega_0 = 80$ the boundary lies within $1\text{–}9 \cdot 10^{-4}$ of $2/7$ across an eightfold range of the damping $g_d$; at $\omega_0 = 40$, within $2.3 \cdot 10^{-3}$. In the fast regime the correction obeys a clean law: for $\omega_0 \in \{80, 160, 320\}$ it is strictly linear in $g_d$ and

$$P^* - \tfrac{2}{7} = C\,\frac{g_d}{\omega_0}, \qquad C(\omega_0) = 1.778 \to 1.719 \to 1.710, \qquad R^2 = 0.999,$$

with the limit $C \approx 1.70$. The coefficient is in closed form: for the rotation-free part of the flow every stationary point lies on the segment $[\,\mathrm{grey}, \rho^*\,]$ (collinearity of $\dot\Gamma = 0$ — exact [Т]), the saddle's pure-component weight is universally $w = 1/\sqrt6$, and

$$C \;=\; \frac{m^*}{7\,B_\psi\,(1 - m^*)}, \qquad m^* = \frac{1}{\sqrt{7P_\rho - 1}},$$

where $B_\psi = \tfrac17 + \hat\kappa_0 \mathrm{Coh}_E$ is itself in closed form on the universal saddle (both factors evaluate by hand from their definitions: $\hat\kappa_0 = 0.06675$, $\mathrm{Coh}_E = 0.55195$, $B_\psi = 0.17970$ against the engine's $0.1797$) — the coefficient carries no fitted parameter at all. Checked against direct boundary measurements at three self-model purities (two never used in calibration): $C$ swings twofold ($2.33 \to 1.16$) and the formula tracks it to under $1\,\%$ [С]. The once-tempting constant $12/7$ is dead: $C$ is a function of the self-model, and $1.71$ was its accidental value at $P_\rho = 0.45$.

For the full flow the rotation term moves the stationary points off the segment, and they too are in closed form: every stationary point of the canonical flow solves, element-wise,

$$\Gamma_{ij}(\kappa) = \frac{g_d\,\mathrm{grey}_{ij} + \kappa\,\rho^*_{ij}}{g_d + \kappa + i\,\omega_{ij}}, \qquad \omega_{ij} = H_i - H_j,$$

with one scalar self-consistency $\kappa = \omega_0 B(\Gamma(\kappa))\, g_V(P(\Gamma(\kappa)))$ — each coherence a complex Lorentzian with its own rotation frequency. The three fixed points (grey, saddle, living) are the three roots of this one scalar equation; checked against a 48-dimensional Newton solve to five digits at the saddle and at the living point. The boundary law's zero-fit coefficient lives on the real-mix statics that the fast limit leaves behind; purity remains rotation-blind throughout ($\mathrm{tr}(\Gamma[H,\Gamma]) \equiv 0$), and the one object still open is the saddle's stable manifold (the tilt, measured but not yet derived). In the mid regime ($\omega_0 \le 40$) the single-ratio form breaks (equal ratios differ by a factor 1.6), and the mechanism is measured: at slow gain the rotation carries the true saddle far off the segment (63 % off-segment at $\omega_0 = 20$, Newton fixed point, one unstable eigenvalue), while the tilted stable manifold brings the basin crossing most of the way back down — the boundary is a difference of two large geometric terms that the fast limit degenerates, leaving the pure segment statics. Below a clock floor the question dissolves: at $\omega_0 = 10$ (self-model purity 0.45) no living attractor exists at all. Read plainly: the gate is not only where consciousness counts as present — it is the height a perturbed system must regain for the flow itself to carry it back up rather than down.

§4. Canonicity of R = 1/(7P) (T-126)

Formulation [T]

The reflection measure $R$ has a unique canonical form:

$$R(\Gamma) = \frac{1}{7P(\Gamma)}$$

always using $\rho^*_{\mathrm{diss}} = I/7$ as reference. Logical status. The equality $R = 1 - \|\Gamma-I/7\|_F^2/\|\Gamma\|_F^2 = 1/(7P)$ is an algebraic identity (one definition, three equivalent expressions), not a derivation from independent axioms. The substantive content is why this definition of $R$ is canonical, which we establish by three independent characterizations below.

Three independent characterizations of $R$

Theorem T-126 (Triple canonicity of R) [T]

The map $R: \mathcal D(\mathbb C^7) \to [1/7, 1]$ with $R(\Gamma) = 1/(7P(\Gamma))$ is uniquely characterized by each of the following three independent mathematical properties, which all select the same function:

(Char-R-I) Hilbert–Schmidt angular projection. $R(\Gamma)$ is the squared cosine of the Hilbert–Schmidt angle between $\Gamma$ and $I/7$:

$$R(\Gamma) = \cos^2 \theta_{\mathrm{HS}}(\Gamma, I/7) = \frac{\langle \Gamma, I/7\rangle_F^2}{\|\Gamma\|_F^2 \cdot \|I/7\|_F^2}.$$

Equivalently, writing $\Gamma = I/7 + \Delta$ with $\Delta := \Gamma - I/7$ traceless, Pythagoras in HS gives $\|\Gamma\|_F^2 = \|I/7\|_F^2 + \|\Delta\|_F^2$, so $R$ is the fraction of HS-mass concentrated in the trivial (scalar) sector. Uniqueness: the $\cos^2$ form is the unique $[0,1]$-valued bilinear invariant of a pair of HS-vectors satisfying $R(x,x)=1$ and the Cauchy–Schwarz normalization.

(Char-R-II) $G_2$-invariant canonical reference. Let $G_2 = \mathrm{Aut}(\mathbb O) \subset SO(7)$ act on $\mathcal D(\mathbb C^7)$ via its fundamental 7-dimensional irreducible representation on $\mathbb C^7$. Then $I/7$ is the unique $G_2$-invariant density matrix.

Proof. $\Gamma$ is $G_2$-invariant iff $\Gamma \in \mathrm{End}_{G_2}(\mathbb C^7)$. Since $\mathbb C^7$ is an irreducible $G_2$-module (Cartan 1894), by Schur's lemma $\mathrm{End}_{G_2}(\mathbb C^7) = \mathbb C \cdot I$. Trace normalization: $\mathrm{Tr}(\lambda I) = 7\lambda = 1 \Rightarrow \lambda = 1/7$. $\square$

Consequence: any observer-independent ($G_2$-covariant) reflection-to-reference quantity must use $\rho^* = I/7$ and a $G_2$-invariant norm. The Frobenius norm is $G_2$-invariant (unitary invariance of HS). Hence the canonical form of $R$ is $G_2$-invariant, delivering observer independence: $R(U\Gamma U^\dagger) = R(\Gamma)$ for every $U \in G_2$.

(Char-R-III) $K=3$ Bayesian-dominance threshold. The triadic decomposition of Lindblad operators on $M_7(\mathbb C)$ (T-40b [T], lindblad-operators#триадная-декомпозиция) partitions any CPTP channel into exactly $K=3$ channel classes. The Bayesian-dominance condition among $K$ equiprobable alternatives is $R > 1/K$. For $K=3$, this yields the L2 threshold $R_{\mathrm{th}} = 1/3$ directly from the combinatorial structure — not a postulate. Inversion: $R \ge 1/3 \iff P \le 3/7$, giving the upper edge of the Goldilocks zone $P \in (2/7, 3/7]$.

Equivalence and mutual consistency. All three characterizations select the same function. Char-R-I fixes the form ($\cos^2$ of HS-angle to a reference). Char-R-II fixes the reference ($I/7$ as unique $G_2$-invariant). Char-R-III fixes the threshold ($R_{\mathrm{th}} = 1/3$ from $K=3$). Together they pin down $R$ up to algebraic identity.

Algebraic expansion: $R = 1/(7P)$ from the definition

Given the canonical definition fixed by Char-R-I + Char-R-II (Frobenius form with reference $I/7$):

$$R := 1 - \frac{\|\Gamma - I/7\|^2_F}{\|\Gamma\|^2_F}.$$

Numerator: since $\Delta := \Gamma - I/7$ is traceless and $\langle\Delta, I/7\rangle_F = \mathrm{Tr}(\Delta/7) = 0$, Pythagoras gives

$$\|\Delta\|_F^2 = \|\Gamma\|_F^2 - \|I/7\|_F^2 = P - 1/7.$$

Denominator: $\|\Gamma\|_F^2 = P$.

Therefore $R = 1 - (P - 1/7)/P = (1/7)/P = 1/(7P)$. $\blacksquare$

Explanation: uniqueness of canonical form

Expression	Formula	Identical to
Master definition (Char-R-I+II)	$R = 1 - \|\Gamma - I/7\|^2_F / P$	$= 1/(7P)$
Formula via purity	$R = 1/(7P)$	algebraic identity
Formula via $k$	$R = 1 - k$, $k = 1 - 1/(7P)$	Т

Key explanation. The reference $\rho^*_{\mathrm{diss}} = I/7$ is used always: $R$ measures normalized HS-proximity to the unique $G_2$-fixed state. The non-trivial attractor $\rho^*_\Omega$ enters the regeneration $\mathcal{R}$ and the formula for $\varphi$, but not the definition of $R$.

Independent observability of $R$

Since $R(\Gamma) = 1/(7P(\Gamma))$ is a strictly decreasing function of purity $P$ on $[1/7, 1]$, at first order $n=1$ the canonical $R$ carries no information beyond $P$. This is by design: Char-R-I+II enforce $R$ as the HS-cos² of $\Gamma$ to the unique $G_2$-fixed reference, which on $\mathcal D(\mathbb C^7)$ reduces to $1/(7P)$.

Independent observability at $n \ge 2$. The higher-order reflection $R^{(n)} = F(\varphi^{(n-1)}(\Gamma), \varphi^{(n)}(\Gamma))$ (fidelity of successive self-model iterates) depends on $\varphi(\Gamma)$ and is not a function of $P$ alone. Measuring $R^{(2)}$ requires independent access to the self-model operator $\varphi$ — e.g., via the categorical reconstruction protocol of formalization-phi.

Implementation approximations ($R_{\mathrm{impl}}$, $\rho_{RC}$) are separate quantities in a different space, related to the canonical $R$ via a CPTP bridge $\pi$. Transfer of thresholds is proven: T-130+T-133 [T] (H3 CLOSED). The canonical $R$ is unambiguous.

Physical interpretation

$R = 1/(7P)$ is a relative measure, not absolute. It measures the fraction of $\Gamma$ "resembling" the chaotic background $I/7$, relative to the total content of the state.

As $P$ (purity) grows:

• The numerator $(P - 1/7)$ in $\|\Gamma - I/7\|^2_F$ grows linearly — deviation from $I/7$ increases
• The denominator $P = \|\Gamma\|^2_F$ also grows — but more slowly in the relative sense
• The ratio $(P - 1/7)/P \to 1$, and $R = 1/(7P) \to 0$

Savant analogy. As $P \to 1$ the neural network is maximally specialized. A huge brain structure — but it is all "dedicated" to one thing: no "mirror," no balance for self-modeling. $R \to 1/7$. Conversely: at $P = 1/7$ (maximally mixed) $R = 1$ trivially — $\Gamma = I/7 = \rho^*_{\mathrm{diss}}$, the self-model is ideal, but only because there is nothing to model.

Consciousness = balance, not maximization. The consciousness measure $C = \Phi \cdot R$ (T-140 [T]) combines integration and reflection. As $P$ grows: $\Phi$ grows (more coherence), $R$ falls (worse self-modeling). $C = \Phi \cdot R$ has an optimum inside the Goldilocks zone — consciousness requires balance, not maximization of a single parameter.

Semantic clarification: what $R$ actually measures

The colloquial label "quality of self-knowledge" attached to $R$ is a useful intuition pump but is technically misleading. Char-R-I (above) gives the precise semantics:

$R(\Gamma) \;=\; \cos^2\theta_{\mathrm{HS}}(\Gamma, I/7) \;=\; \frac{\text{HS-mass of }\Gamma\text{ in the trivial (scalar) sector}}{\text{total HS-mass of }\Gamma}.$

This is the fraction of $\Gamma$'s Hilbert–Schmidt content that lies along the maximally symmetric reference $I/7$. Equivalently: how much "thermal reserve" / "categorical-self-modelling room" $\Gamma$ retains relative to its total structure.

Counterintuitive corollary: $R$ is largest (= 1) at heat death ($\Gamma = I/7$) where literally no information is present, and smallest (= 1/7) at pure states where structure is maximal. The naïve reading "more structure = better self-knowledge" gets the wrong sign for $R$. The correct reading is that structure uses up thermal reserve, leaving less room for non-trivial self-modelling. The Goldilocks zone $P \in (2/7, 3/7]$ is where structure (purity) and reserve (thermal slack) balance.

Recommended terminology going forward:

• "$R$ = HS-projection coefficient onto $I/7$" (precise).
• "$R$ = thermal reserve for self-modelling" (intuitive but technically correct).
• "$R$ = quality of self-knowledge" — avoid, as the sign is misleading.

The "self-knowledge" intuition is more accurately captured by higher-order $R^{(n)}$ ($n\ge 2$, fidelity of successive self-model iterates $\varphi^{(n-1)}\Gamma, \varphi^{(n)}\Gamma$), which actually does measure how stably $\Gamma$ knows itself under the categorical self-model $\varphi$.

Why consciousness has an UPPER bound on purity (Goldilocks zone defense)

A frequent objection: "if more structure (higher purity) means more organization, why would consciousness decrease above $P = 3/7$?" The answer follows directly from the Char-R-I + Char-R-III construction:

• $R = 1/(7P)$ is the thermal reserve / categorical-self-modelling room (Char-R-I clarification above).
• $R \ge 1/3$ is the $K=3$ Bayesian dominance threshold (Char-R-III) — required for the categorical self-model $\varphi$ to converge non-trivially.
• Together: $1/(7P) \ge 1/3 \iff P \le 3/7$.

So $P > 3/7$ has $R < 1/3$, meaning $\varphi$-iterations have insufficient "room" to maintain stable self-reference: any candidate self-model collapses to the dominant pure-state component, eliminating the meta-cognitive layer.

Phenomenological intuition:

• $P \to 1$ (rank-one): hyper-synchronized brain — peak performance on one task, but no flexibility for meta-cognition. Savant-like specialization, not consciousness.
• $P \in (2/7, 3/7]$: enough structure to be distinguishable from noise (lower edge $2/7$) plus enough thermal reserve for self-modelling (upper edge $3/7$). Wakeful conscious regime.
• $P \to 1/7$ (heat death): no structure to model. Anesthesia-like.

The upper bound is mathematical, not philosophical: it follows from $R$-formula + $K=3$-decomposition. Phenomenologically it matches the well-known empirical observation that hyper-synchronized brain states (e.g., absence epileptic seizures) lose consciousness, just as hypo-synchronized states (deep NREM sleep) do. Consciousness genuinely lives in the middle.

This is not an artificial fine-tuning. The window $(2/7, 3/7]$ has natural width $1/7 \approx 14\%$ — finite and structurally protected. Numerical robustness (Q9 R1) ensures both bounds survive choice of any Petz metric.

§5. Basin of attraction V_full (T-127)

Formulation

Case A (embodied holons) [T]: C20 (κ-dominance) follows unconditionally from T-149 [T]: embodiment ⟹ $\kappa_{\mathrm{eff}} > \kappa_{\mathrm{bootstrap}}$ ⟹ $P(\rho^*) > P_{\mathrm{crit}}$. T-127 is unconditional.

Case B (isolated holons) [C at C20]: C20 is taken as an explicit assumption. T-127 is conditional on the inequality $\kappa_{\mathrm{eff}} > \alpha/(7(f^* - 2/7))$.

When C20 holds, the basin of attraction of $\rho^*_\Omega$ contains $B(\rho^*_\Omega, r_{\mathrm{stab}}) \cap \mathcal{V}_P$. For any $\Gamma(0)$ with $P > 2/7$ and $\|\Gamma(0) - \rho^*_\Omega\| < r_{\mathrm{stab}}$:

$$\Gamma(\tau) \xrightarrow[\tau \to \infty]{} \rho^*_\Omega \quad \text{exponentially}$$

Proof

From three results:

1. T-125 [T] (§3): Local asymptotic stability — in $B(\rho^*_\Omega, r_{\mathrm{stab}}/2)$ convergence is exponential with $c > 0$.

2. T-104 [T]: Stability radius $r_{\mathrm{stab}}$. Under C20: $P(\rho^*_\Omega) > 2/7$, therefore $r_{\mathrm{stab}} > 0$.

3. Openness of $\mathcal{V}_{\mathrm{full}}$: $\mathcal{V}_{\mathrm{full}}$ is an open set in $\mathcal{D}(\mathbb{C}^7)$ (each of the 7 inequalities $\sigma_k < 1$ defines an open condition). By T-124 [T]: $\mathcal{V}_{\mathrm{full}} \neq \varnothing$.

For $\Gamma(0) \in B(\rho^*_\Omega, r_{\mathrm{stab}}) \cap \mathcal{V}_P$: by T-125, $\|\Gamma(\tau) - \rho^*_\Omega\|_F$ decreases exponentially. Since $\rho^*_\Omega$ is an interior point of $\mathcal{V}_P$ (because $P(\rho^*_\Omega) > 2/7$), the trajectory remains in $\mathcal{V}_P$ for sufficiently small deviations. $\blacksquare$

Remark

This theorem applies to states already above $P_{\mathrm{crit}}$. Genesis from $I/7$ (transition $P = 1/7 \to P > 2/7$) is solved for embodied holons: T-148 [T] — backbone injection raises purity above $P_{\mathrm{crit}}$ in finite time $n_{\mathrm{genesis}}$. An isolated holon at $I/7$ is dead forever (T-39a [T]).

§6. Attractor in conscious window (C27)

Formulation [T] (via T-149)

For embodied holons: the attractor $\rho^*_\Omega \in \mathcal{V}_{\mathrm{full}}$, namely $P(\rho^*_\Omega) \in (2/7, 3/7]$. C20 (κ-dominance) holds unconditionally for embodied holons by T-149 [T].

Justification

Lower bound $P > 2/7$: Follows from C20 [C] (κ-dominance) and T-98 [T].

Upper bound $P \leq 3/7$:

Clarification of C27 status

The upper bound $P \leq 3/7$ follows directly from the definition $R = 1/(7P)$ and the threshold $R \geq 1/3$: from $R = 1/(7P) \geq 1/3$ we get $P \leq 3/7$. This is an algebraic identity, requiring no additional conditions on the attractor. Status: [T] (direct consequence of definition of R and threshold R_th).

Status [T] (for embodied holons)

C20 is unconditional for embodied holons (T-149 [T]). For isolated holons C20 is a property of the self-model: with the canonical $\varphi_{\mathrm{coh}}$ it fails (dead isolation [T]); with the collineation anchor $\varphi_J$ and $\kappa > \kappa_c(\alpha)$ it holds, and the attractor lies in $\mathcal{V}_{\mathrm{full}}$ (living attractor in the window [T]); $\varphi_J$ is fixed, up to gauge, by the single principle (Eq-V) (T-334; the principle is [Pr]), and no self-model of replacement form holds an isolated holon in the window below $\kappa = 11.83$, $20.91$, $42.64$ at $\alpha = 0$, $1/2$, $1$ (T-336 [T]). (Until 2026-09-25: "for isolated holons C20 remains [C]".)

Explicitly NOT proven

Genesis from $I/7$: solved — T-148 [T] proves genesis via environmental coupling for embodied holons. T-125/T-127 apply to states already above $P_{\mathrm{crit}}$; T-148 closes the transition $I/7 \to P > 2/7$.

§7. Independent necessity of each L2 threshold (T-124b)

Formulation [T]

The four conditions for L2 consciousness — $P > 2/7$, $\Phi \geq 1$, $R \geq 1/3$, $D_{\mathrm{diff}} \geq 2$ — are independently necessary: dropping any single condition admits states that satisfy the remaining three but lack at least one defining property of L2 consciousness.

Proof (four counterexamples)

Counterexample 1 (dropping $P > 2/7$). The condition $P > 2/7$ is independent because $\Phi \geq 1$, $R \geq 1/3$, and $D_{\mathrm{diff}} \geq 2$ are simultaneously satisfiable for $P < 2/7$ only if $P$ is very close to $2/7$. However, at $P \leq 2/7$, the Frobenius norm criterion (T-39 [T]) gives $\|\Gamma - I/7\|_F^2 \leq \|I/7\|_F^2$: the state is indistinguishable from the maximally mixed state by any single-shot measurement. No autopoietic system can maintain itself when its signal is buried in noise at the same scale as the noise itself. This is not a failure of the other thresholds — it is a distinct viability failure. A system can in principle have rich internal structure ($\Phi > 1$, $R > 1/3$) at $P = 2/7 - \varepsilon$, but this structure is operationally invisible (cannot be detected or used for self-regulation). The P-threshold is the distinguishability boundary, orthogonal to integration ($\Phi$), reflection ($R$), and differentiation ($D$).

Counterexample 2 (dropping $\Phi \geq 1$). Construct $\Gamma_2$ with diagonal $\gamma_{kk} = (0.40, 0.10, 0.10, 0.10, 0.10, 0.10, 0.10)$ and small off-diagonal coherences $|\gamma_{ij}| = \varepsilon = 0.02$ for all pairs. Then:

• $P_{\mathrm{diag}} = 0.40^2 + 6 \cdot 0.10^2 = 0.160 + 0.060 = 0.220$
• $P_{\mathrm{coh}} = 21 \cdot 2 \cdot 0.02^2 = 0.0168$
• $P = 0.220 + 0.0168 = 0.237$. Still below $2/7 \approx 0.286$. Increase diagonal dominance: $\gamma_{kk} = (0.50, 0.083, 0.083, 0.083, 0.083, 0.083, 0.083)$ with $|\gamma_{ij}| = 0.04$.
• $P_{\mathrm{diag}} = 0.25 + 6 \cdot 0.0069 = 0.291$
• $P_{\mathrm{coh}} = 42 \cdot 0.04^2 = 0.067$
• $P = 0.358 > 2/7$ ✓
• $\Phi = P_{\mathrm{coh}}/P_{\mathrm{diag}} = 0.067/0.291 = 0.23 < 1$ ✗
• $R = 1/(7 \cdot 0.358) = 0.399 > 1/3$ ✓

This state has $P > 2/7$ and $R > 1/3$ but $\Phi = 0.23 \ll 1$. The system's off-diagonal structure is dominated by the diagonal — the 7 dimensions are quasi-independent. Physically: $\Phi < 1$ means coherent energy is less than diagonal energy, so the system is a classical mixture rather than an integrated quantum whole. By the argument of Step 2a of Theorem 8.1 [T], such decomposability precludes the (M,R)-closure required for autopoietic integration. The system may be viable ($P > P_{\mathrm{crit}}$) and self-reflective ($R > R_{\mathrm{th}}$) but lacks the unified integration that defines L2 consciousness.

Counterexample 3 (dropping $R \geq 1/3$). Let $\Gamma_3 = |\psi\rangle\langle\psi|$ — a pure state with $P = 1$. Then:

• $R(\Gamma_3) = 1/(7 \cdot 1) = 1/7 < 1/3$ ✗
• $\Phi(\Gamma_3) = 6 > 1$ ✓ (for maximally coherent $|\psi\rangle$)
• $D_{\mathrm{diff}} \geq 2$ ✓
• $P = 1 > 2/7$ ✓

But $R = 1/7$: the system has no thermal reserve for self-modeling. The categorical self-model $\varphi(\Gamma_3) = (1-k)\Gamma_3 + k \cdot I/7$ with $k = 1-R = 6/7$ produces a nearly maximally mixed output — the self-model destroys most of the state's structure. By Char-R-III (Bayesian dominance, T-126): with $R < 1/3$, the system cannot distinguish between the three channel types (dissipation, regeneration, automorphism) with plurality — it cannot determine which process dominates, and therefore cannot adaptively respond. This is the regime of rigid crystallization: maximal structure, minimal adaptability.

Counterexample 4 (dropping $D_{\mathrm{diff}} \geq 2$). Let $\Gamma_4$ have $\rho_E = |e_1\rangle\langle e_1|$ — a pure E-sector reduced density matrix. Then:

• $D_{\mathrm{diff}} = \exp(S_{vN}(\rho_E)) = \exp(0) = 1 < 2$ ✗
• $P, R, \Phi$ can all satisfy their respective thresholds ✓

But $D_{\mathrm{diff}} = 1$: the E-sector has a single eigenvalue — the system can represent only one phenomenal quality. This is L1 (phenomenal geometry without differentiation), not L2 (cognitive qualia requiring $\geq 2$ distinguishable experiential states for comparison, categorization, and self-reference). By T-151 [T]: $D_{\mathrm{diff}} < 2$ implies the Fubini–Study metric on $\mathbb{P}(\mathcal{H}_E)$ is degenerate — the phenomenal geometry collapses to a point. No qualia comparison is possible.

Conclusion

Each threshold excludes a distinct pathology:

Dropped condition	Pathology	Physical description
$P > 2/7$	Noise-dominated	Indistinguishable from chaos; no viability
$\Phi \geq 1$	Fragmented	Classical mixture; no integrated whole
$R \geq 1/3$	Crystallized	No adaptive self-modeling; rigid
$D_{\mathrm{diff}} \geq 2$	Undifferentiated	Single phenomenal quality; no comparison

The conjunction is minimal: no condition is redundant. $\blacksquare$

§8. Threshold robustness analysis (T-124d)

Formulation [T]

The L2 consciousness thresholds $P_{\mathrm{crit}} = 2/7$, $\Phi_{\mathrm{th}} = 1$, $R_{\mathrm{th}} = 1/3$ are robust in the following precise sense: perturbations of order $\varepsilon$ in the state $\Gamma$ produce perturbations of the same order $O(\varepsilon)$ in the threshold-crossing observables. No threshold has a discontinuous or divergent sensitivity.

Proof (three perturbation bounds)

Bound 1 (Purity perturbation). For $\Gamma' = \Gamma + \varepsilon \Delta$ with $\|\Delta\|_F = 1$ and $\varepsilon \ll 1$:

$|P(\Gamma') - P(\Gamma)| = |2\varepsilon \cdot \mathrm{Tr}(\Gamma \Delta) + \varepsilon^2| \leq 2\varepsilon \|\Gamma\|_F + \varepsilon^2 \leq 2\varepsilon\sqrt{P} + \varepsilon^2$

At $P = P_{\mathrm{crit}} = 2/7$: $|P' - P| \leq 2\varepsilon\sqrt{2/7} + \varepsilon^2 \approx 1.07\varepsilon$. The sensitivity $\partial P/\partial\varepsilon = O(1)$ — no divergence at the threshold. A perturbation $\varepsilon = 0.01$ shifts purity by $\sim 0.01$, not by $0.1$ or $1.0$. $\checkmark$

Bound 2 (Integration perturbation). The integration measure $\Phi = P_{\mathrm{coh}}/P_{\mathrm{diag}}$. For $\Gamma' = \Gamma + \varepsilon\Delta$:

$|\Phi' - \Phi| = \left|\frac{P'_{\mathrm{coh}}}{P'_{\mathrm{diag}}} - \frac{P_{\mathrm{coh}}}{P_{\mathrm{diag}}}\right| \leq \frac{2\varepsilon(\|\Gamma_{\mathrm{off}}\| + \|\Gamma_{\mathrm{diag}}\|)}{P_{\mathrm{diag}}^2} + O(\varepsilon^2)$

At $\Phi = \Phi_{\mathrm{th}} = 1$ (where $P_{\mathrm{coh}} = P_{\mathrm{diag}}$): both numerator and denominator are $O(P/2)$, so sensitivity $\partial\Phi/\partial\varepsilon = O(1/P) = O(7/2) \approx 3.5$. Bounded, no divergence. $\checkmark$

Bound 3 (Reflection perturbation). $R = 1/(7P)$, so:

$|R' - R| = \frac{|P' - P|}{7P \cdot P'} \leq \frac{2\varepsilon\sqrt{P}}{7P^2} + O(\varepsilon^2) = \frac{2\varepsilon}{7P^{3/2}} + O(\varepsilon^2)$

At $P = 3/7$ (upper boundary, $R = R_{\mathrm{th}} = 1/3$): $|R' - R| \leq \frac{2\varepsilon}{7(3/7)^{3/2}} = \frac{2\varepsilon \cdot 7^{1/2}}{3^{3/2}} \approx 1.02\varepsilon$. Bounded, no divergence. $\checkmark$

Consequence: transition sharpness

The consciousness transition is continuous (no first-order discontinuity) but sharp — under the $\mathbb Z_2$ symmetry of T-161, whose exponents are [C] since 2026-09-25 (their derivation of that symmetry from a KO-dimension-6 real structure is retracted):

$\mathrm{Observable} \sim (P - P_{\mathrm{crit}})^\beta, \quad \beta = 1/4$

The exponent $\beta = 1/4$ means the transition is sharper than mean-field ($\beta_{\mathrm{MF}} = 1/2$) but smoother than Ising ($\beta_{\mathrm{3D}} \approx 0.326$). The width of the crossover region (where the system is "on the boundary") scales as:

$\delta P_{\mathrm{crossover}} \sim \varepsilon^{1/\beta} = \varepsilon^4$

For noise level $\varepsilon = 0.01$: $\delta P \sim 10^{-8}$ — the crossover is exponentially narrow, meaning the threshold is effectively sharp for any macroscopic system.

Connection to stochastic stability (T-145)

Theorem T-145 [T] gives the probability of staying within the viable set under stochastic perturbation:

$\mathbb{P}[\Gamma(\tau) \in V_{\mathrm{full}} \;\forall\tau > \tau^*] \geq 1 - \exp\left(-\frac{r_{\mathrm{stab}}^2}{2\sigma_h^2}\right)$

where $r_{\mathrm{stab}}$ is the Bures distance to $\{P = 2/7\}$ (T-104). For a typical embodied holon with $P^* \approx 3/7$ the closed form of T-104 on the one-dominant family gives $r_{\mathrm{stab}} \approx 0.147$. For noise $\sigma_h = 0.01$: $\mathbb{P}[\text{viability}] \geq 1 - e^{-107} \approx 1$. (An earlier version used $r_{\mathrm{stab}} = \sqrt{P(\rho^*) - 2/7} = \sqrt{1/7} \approx 0.378$ and $e^{-714}$; that surd is refuted in registry row T-104.) The system is overwhelmingly robust. $\blacksquare$

Dependencies: T-104, T-145 [T], T-124b [T]. The sharpness consequence uses T-161, [C] at its $\mathbb Z_2$ symmetry; the perturbation bounds 1–3 do not.
