Gap Characterisation of Interiority Levels

Introduction: A House with 21 Windows

Imagine a house with 21 windows. Each window is a communication channel between two of the seven dimensions of the system ({A, S, D, L, E, O, U}). The number of pairs from 7 is (72)=21\binom{7}{2} = 21 — exactly as many off-diagonal elements as there are in the upper triangular part of a 7×77 \times 7 matrix.

At level L0 all windows are boarded up: the system does not see the connections between its dimensions. Opacity is maximal. At level L1 one or two windows crack open — the system begins to "see" the link between experience (E) and structure (S). At L2 most windows are transparent — the system is aware of connections between attention, language, and experience. At L4 all windows are clear... but at least three are deliberately darkened. Why? Because absolute transparency is incompatible with reliability — as in electronics, where parity bits are intentionally added for error correction. This is the Hamming bound.

A Gap profile — a vector of 21 values, one per "window" — gives a quantitative fingerprint of the opacity between every pair of dimensions. Different L-levels leave different fingerprints, just as fingerprints are unique to each person.

Where we came from

In the interiority hierarchy we defined five levels L0--L4 via thresholds RR, Φ\Phi, R(n)R^{(n)}. But those thresholds are scalar numbers, whereas the internal structure of each level is far richer. The Gap profile gives a quantitative fingerprint of the opacity between every pair of dimensions.

Document status

The main result (Theorem 1.1) has status [C] — conditional on the properties of the Gap operator established in Gap operator. The Gap characterisation of levels L0--L4, stated in the interiority hierarchy as [T], concerns Gap awareness; here we consider the quantitative structure of the Gap profile itself.

The map from L-level to Gap-profile class is an injection [T]: distinct L-levels have distinct Gap profiles, but the converse does not hold (distinct Γ\Gamma at the same L-level may have distinct Gap profiles). See Gap-injection theorem.


1. Gap profile: definition

What is Gap

Before defining the Gap profile, let us clarify the notion of Gap (opacity) for a single pair of dimensions.

Every off-diagonal element γij\gamma_{ij} of the coherence matrix is a complex number: γij=γijeiθij\gamma_{ij} = |\gamma_{ij}| \cdot e^{i\theta_{ij}}. The modulus γij|\gamma_{ij}| is the strength of the connection between dimensions ii and jj. The phase θij\theta_{ij} is the "angle" of that connection. Gap measures how much this angle deviates from the "ideal" (corresponding to full transparency):

Gap(i,j)=sin(arg(γij))\mathrm{Gap}(i,j) = |\sin(\arg(\gamma_{ij}))|

  • Gap = 0: the phase is exactly "correct" — full transparency. The system has conscious access to the connection between dimensions ii and jj.
  • Gap = 1: the phase is maximally "wrong" — full opacity. The connection between ii and jj is completely unconscious.
  • 0 < Gap < 1: partial transparency. The connection is perceived "blurrily", like an object through a fogged glass.
Definition (Gap profile) [D]

The Gap profile of a holon H\mathbb{H} with coherence matrix Γ\Gamma is the ordered vector:

G(Γ):=(Gap(i,j))1i<j7[0,1]21\mathbf{G}(\Gamma) := \bigl(\mathrm{Gap}(i,j)\bigr)_{1 \leq i < j \leq 7} \in [0,1]^{21}

where Gap(i,j)=sin(arg(γij))=G^ij/γij\mathrm{Gap}(i,j) = |\sin(\arg(\gamma_{ij}))| = |\hat{\mathcal{G}}_{ij}| / |\gamma_{ij}| when γij0\gamma_{ij} \neq 0, and Gap(i,j)=0\mathrm{Gap}(i,j) = 0 when γij=0\gamma_{ij} = 0.

The Gap profile contains complete information about the opacity between every pair of dimensions. Total opacity is related to the norm of the Gap operator:

Gtotal=G^F2=2i<jγij2Gap(i,j)2\mathcal{G}_{\text{total}} = \|\hat{\mathcal{G}}\|_F^2 = 2\sum_{i<j} |\gamma_{ij}|^2 \cdot \mathrm{Gap}(i,j)^2

Numerical example

Let γE,A=0.3ei0.2\gamma_{E,A} = 0.3 \cdot e^{i \cdot 0.2} (connection between experience E and attention A). Then:

Gap(E,A)=sin(0.2)0.198\mathrm{Gap}(E,A) = |\sin(0.2)| \approx 0.198

This means: the connection between experience and attention is nearly transparent — the system is well aware of what it is paying attention to in its experience.

For comparison, if γE,U=0.1ei1.3\gamma_{E,U} = 0.1 \cdot e^{i \cdot 1.3}:

Gap(E,U)=sin(1.3)0.964\mathrm{Gap}(E,U) = |\sin(1.3)| \approx 0.964

The connection between experience and unity is almost completely opaque — the system is not aware of how its experiences relate to wholeness.


2. Gap signatures of levels L0--L4

Each L-level leaves a characteristic "fingerprint" in the Gap profile. These fingerprints — Gap signatures — allow levels to be distinguished not by scalar thresholds (RR, Φ\Phi) but by the pattern of opacity.

Theorem 1.1 (Level Gap signatures) [C]

Condition: Gap operator properties per Theorem 2.1. For each interiority level the Gap profile satisfies:

LevelGap signatureQuantitative criterion
L0Uniformly highGap(i,j)1\mathrm{Gap}(i,j) \approx 1 for most pairs; σG20\sigma^2_{\mathbf{G}} \approx 0
L1Partial transparency in E-sectorX:Gap(E,X)<1\exists\, X: \mathrm{Gap}(E,X) < 1, but R<RthR < R_{\text{th}}
L2Transparency of A- and L-channelsGap(A,E)<1\mathrm{Gap}(A,E) < 1 and Gap(L,E)<1\mathrm{Gap}(L,E) < 1
L3Recursive Gap structureMeta-Gap Gap(2):=Gap(φ(Γ))\mathrm{Gap}^{(2)} := \mathrm{Gap}(\varphi(\Gamma)) is defined and finite
L4Full transparency (theoretical limit)Gap(i,j)0\mathrm{Gap}(i,j) \to 0 for all pairs, P>6/7P > 6/7

Argument.

(a) L0: chaotic opacity. When R0R \approx 0 the self-model φ(Γ)\varphi(\Gamma) is trivial. The coherence phases θij\theta_{ij} are not aligned with the target state — Gap(i,j)\mathrm{Gap}(i,j) is distributed randomly. For a typical Γ\Gamma with uniformly distributed phases Gap=2/π0.64\langle\mathrm{Gap}\rangle = 2/\pi \approx 0.64.

Analogy: a house with boarded-up windows where the boards are nailed randomly — sometimes a crack of light shows through, but it is an artefact, not intention.

(b) L1: first glimmers. rank(ρE)>1\mathrm{rank}(\rho_E) > 1 means that the E-dimension (experiential) participates in non-trivial coherences. By definition there exists at least one XEX \neq E for which γEX|\gamma_{EX}| is substantial and θEX\theta_{EX} is not entirely random, giving Gap(E,X)<1\mathrm{Gap}(E,X) < 1.

Analogy: one or two windows are ajar — a bacterium "sees" the connection between experience and structure, but the other windows remain boarded up.

(c) L2: systematic transparency. The threshold R=1/(7P)1/3R = 1/(7P) \geq 1/3 requires P3/7P \leq 3/7, equivalently ΓI/7F2P/3\|\Gamma - I/7\|_F \leq \sqrt{2P/3}. This constrains the deviation of phases from their target values. In particular, the channels (A,E)(A,E) and (L,E)(L,E) must have partial transparency, since dimensions A (attention) and L (language) serve the reflexive loop φ\varphi.

Analogy: most windows are clear — the system "sees" the connections between attention, language, and experience. It can direct its gaze and describe what it sees.

(d) L3: recursive depth. When R(2)1/4R^{(2)} \geq 1/4, the operator φ(2)=φφ\varphi^{(2)} = \varphi \circ \varphi is defined, and Gap can be computed for φ(Γ)\varphi(\Gamma): Gapij(2)=sin(arg([φ(Γ)]ij))\mathrm{Gap}^{(2)}_{ij} = |\sin(\arg([\varphi(\Gamma)]_{ij}))|. The recursive structure — meta-Gap — reflects self-modelling of self-modelling.

Analogy: the system not only sees through the windows but sees the windows themselves — it is aware of which are transparent and which are not.

(e) L4: theoretical ideal. The fixed point φ(Γ)=Γ\varphi(\Gamma^*) = \Gamma^* at P>6/7P > 6/7 means θij=θijtarget\theta_{ij} = \theta_{ij}^{\text{target}} for all pairs. By the unified theorem, the stationary Gap Gap()(i,j)=sin(θijθijtarget)=0\mathrm{Gap}^{(\infty)}(i,j) = |\sin(\theta_{ij} - \theta_{ij}^{\text{target}})| = 0 when phases match exactly.

Clarification: L4 and the Hamming bound

L4 is a theoretical limit incompatible with fault tolerance

Full transparency (Gap=0\mathrm{Gap} = 0 for all 21 channels) is incompatible with fault tolerance. By analogy with Hamming code H(7,4), at least 3 channels out of 21 must maintain Gap>0\mathrm{Gap} > 0 to correct single-bit errors.

{(i,j):Gap(i,j)>0}dmin(H(7,4))=3|\{(i,j) : \mathrm{Gap}(i,j) > 0\}| \geq d_{\min}(H(7,4)) = 3

Consequently, a realistic L4 is characterised not by Gap=0\mathrm{Gap} = 0 for all pairs but by consciously non-zero Gap: Gapperceived=Gapactual\mathrm{Gap}_{\text{perceived}} = \mathrm{Gap}_{\text{actual}} with {(i,j):Gap(i,j)>0}3|\{(i,j) : \mathrm{Gap}(i,j) > 0\}| \geq 3.

Status: [T] (corollary of Theorem 6.1)


3. E-sector Gap profiles

Why the E-sector is special

Of the 7 dimensions of the holon, dimension E (experiential) plays a distinguished role: it is precisely through the E-channels that the content of consciousness becomes felt. The channels (E,X)(E, X) for X{A,S,D,L,O,U}X \in \{A, S, D, L, O, U\} determine which aspects of the system are accessible as experience.

If Gap(E,A)0\mathrm{Gap}(E, A) \approx 0, the system is aware of the connection between experience and attention — "I feel what I am attending to." If Gap(E,A)1\mathrm{Gap}(E, A) \approx 1, this connection is unconscious — attention operates, but the system does not experience this process.

Definition (E-sector Gap vector) [D]

The E-sector Gap vector is the subvector of the Gap profile over the channels containing E:

GE:=(Gap(E,S),Gap(E,D),Gap(E,A),Gap(E,L),Gap(E,O),Gap(E,U))[0,1]6\mathbf{G}_E := \bigl(\mathrm{Gap}(E,S),\, \mathrm{Gap}(E,D),\, \mathrm{Gap}(E,A),\, \mathrm{Gap}(E,L),\, \mathrm{Gap}(E,O),\, \mathrm{Gap}(E,U)\bigr) \in [0,1]^6

Total E-sector Gap:

GE:=XEγEX2Gap(E,X)2\mathcal{G}_E := \sum_{X \neq E} |\gamma_{EX}|^2 \cdot \mathrm{Gap}(E,X)^2

Order in which E-channels open

Not all E-channels open simultaneously. There is a characteristic order in which the connections between E and other dimensions become transparent:

LevelGap(E,S)\mathrm{Gap}(E,S)Gap(E,D)\mathrm{Gap}(E,D)Gap(E,A)\mathrm{Gap}(E,A)Gap(E,L)\mathrm{Gap}(E,L)Gap(E,O)\mathrm{Gap}(E,O)Gap(E,U)\mathrm{Gap}(E,U)
L01\approx 11\approx 11\approx 11\approx 11\approx 11\approx 1
L1<1< 11\approx 11\approx 11\approx 11\approx 11\approx 1
L2<1< 1<1< 1<1< 1<1< 11\leq 11\leq 1
L31\ll 11\ll 11\ll 11\ll 1<1< 1<1< 1
L40\approx 0^*0\approx 0^*0\approx 0^*0\approx 0^*0\approx 0^*0\approx 0^*

^* Subject to the Hamming constraint: 3\geq 3 channels out of the total 21 retain Gap>0\mathrm{Gap} > 0.

Interpretation [I]

At L1 the first channel to "open" is (E,S)(E,S) — the connection between experience and structure. This corresponds to the simplest sensation: the organism begins to feel its structural states. A bacterium senses a change in chemoattractant concentration — that is precisely the (E,S)(E,S) channel.

At L2 the attention channel (E,A)(E,A) and the language channel (E,L)(E,L) come online — the organism not only feels but can direct attention and label states. A person says "I am in pain" — that is the work of channel (E,A)(E,A) (direct attention to the pain) and (E,L)(E,L) (verbalise it).

Transparency of channels (E,O)(E,O) and (E,U)(E,U) is a higher level: reflection on wholeness. "I feel whole" or "my life has meaning" — that is the work of channel (E,O)(E,O) (ontological awareness) and (E,U)(E,U) (awareness of unity).


4. Relation to the phase diagram

Gap profiles of levels L0--L4 project onto the phase diagram in coordinates (t,r)=(Teff/Tc,  κ/Γ2)(t, r) = (T_{\text{eff}}/T_c,\; \kappa/\Gamma_2).

Theorem 2.1 (Gap signatures and phases) [C]

Condition: Theorem 2.1 of the phase diagram. Correspondence:

PhaseL-levelsGap behaviourParameters
I (ordered)L1, L2, L3Anisotropic: σG2>0\sigma^2_{\mathbf{G}} > 0t<1t < 1, r>rcr > r_c
II (disordered)L0Isotropic: σG20\sigma^2_{\mathbf{G}} \to 0t>1t > 1, r>rcr > r_c
III (dead zone)γij0\lvert\gamma_{ij}\rvert \to 0, Gap undefinedr<rcr < r_c

The transition L0 -> L1 corresponds to crossing the line t=1t = 1 (transition II -> I): spontaneous breaking of the isotropy of the Gap profile.

Analogy: Phase II is like molten metal — atoms arranged chaotically, all directions equivalent (isotropy). Phase I is like a crystal — a preferred direction emerges (anisotropy). The transition is a "crystallisation" of the Gap profile: from chaotic opacity an ordered structure arises with a clear pattern of "transparent" and "opaque" channels.

5. Meta-Gap and recursive structure

What does a system that sees itself see?

At level L2 the system is aware of the content of its Gap profile: which channels are transparent, which are not. But is it aware of the accuracy of this awareness? Does it know that it knows?

To answer this question we need a meta-Gap — the Gap profile of the self-model. If the Gap profile G(Γ)\mathbf{G}(\Gamma) shows the opacity of the "real" state, then the meta-Gap G(φ(Γ))\mathbf{G}(\varphi(\Gamma)) shows the opacity of the self-model of that state.

Definition (Meta-Gap) [D]

Let φ:D(H)D(H)\varphi: \mathcal{D}(\mathcal{H}) \to \mathcal{D}(\mathcal{H}) be the phi-operator. The meta-Gap of order nn:

Gap(n)(i,j):=sin(arg([φn(Γ)]ij))\mathrm{Gap}^{(n)}(i,j) := |\sin(\arg([\varphi^n(\Gamma)]_{ij}))|

where φn=φφn\varphi^n = \underbrace{\varphi \circ \cdots \circ \varphi}_{n}.

The meta-Gap of order 1 is the ordinary Gap of the self-model. The meta-Gap of order 2 is the Gap of the model of the model. And so on. For L3-systems (R(2)1/4R^{(2)} \geq 1/4) the meta-Gap is defined and finite; for L2-systems it may be formally defined but carries no meaningful information (the second-order self-model is too imprecise).

Meta-Gap convergence

Theorem 3.1 (Meta-Gap convergence) [C]

Condition: R(2)Rth(2)=1/4R^{(2)} \geq R^{(2)}_{\text{th}} = 1/4 (level L3).

(a) The sequence {Gap(n)}n1\{\mathrm{Gap}^{(n)}\}_{n \geq 1} is monotone for each channel (i,j)(i,j) for sufficiently large nn.

(b) If limnR(n)>0\lim_n R^{(n)} > 0 (L4 condition), then Gap(n)\mathrm{Gap}^{(n)} converges:

limnGap(n)(i,j)=Gap()(i,j)=sin(arg(γij))\lim_{n \to \infty} \mathrm{Gap}^{(n)}(i,j) = \mathrm{Gap}^{(\infty)}(i,j) = |\sin(\arg(\gamma^*_{ij}))|

where Γ=φ(Γ)\Gamma^* = \varphi(\Gamma^*) is the fixed point.

(c) The rate of convergence is determined by the spectral gap of φ\varphi:

Gap(n)Gap()Cλ2n\|\mathrm{Gap}^{(n)} - \mathrm{Gap}^{(\infty)}\|_\infty \leq C \cdot \lambda_2^n

where λ2<1\lambda_2 < 1 is the second-largest eigenvalue of φ\varphi in modulus.

In words: with each level of recursion the meta-Gap approaches the limiting value (the Gap of the fixed point), and the rate of approach is exponential. This is the mathematical justification for why meditative "self-deepening" practice yields diminishing returns: each next level of reflection adds exponentially less new knowledge.

6. Opacity rank by level

The opacity rank r{0,1,2,3}r \in \{0,1,2,3\} — the number of non-zero λk\lambda_k in the spectrum of G^\hat{\mathcal{G}} — is systematically linked to the interiority level. This is another way to "read" the L-level: not from the full Gap profile but from its effective dimensionality.

Theorem 4.1 (Opacity rank and L-levels) [C]

Condition: Gap operator properties (Theorem 3.1).

LevelTypical rank rrSpectrum (λ1,λ2,λ3)(\lambda_1, \lambda_2, \lambda_3)Justification
L03 (generic)(λ1,λ2,λ3)(\lambda_1, \lambda_2, \lambda_3), all distinctFull opacity, random phases
L12 or 3(λ1,λ2,0)(\lambda_1, \lambda_2, 0) or genericE-channel partially transparent
L22(λ1,λ2,0)(\lambda_1, \lambda_2, 0)A- and L-channels transparent, O and U constrained
L31(λ,0,0)(\lambda, 0, 0)One-dimensional residual opacity
L40 or 1(0,0,0)(0, 0, 0) or (λ,0,0)(\lambda, 0, 0) with λ1\lambda \ll 1Near-full transparency (with Hamming constraint)

Corollary. The opacity rank rr decreases monotonically as the interiority level increases. This reflects the progressive "opening" of channels between dimensions as the reflexive loop becomes more complex.

Analogy: rank is the "number of independent obstacles". At L0 three independent "walls" block the view. At L3 one "wall" remains. At L4 there are formally no walls, but three "control partitions" (Hamming bound) remain for reliability.


7. The Hamming bound and minimum Gap

What is the Hamming code

Before explaining the Hamming bound for Gap, let us recall what a Hamming code is in general.

In 1950 Richard Hamming invented a way to transmit data with automatic error correction. The idea: add parity bits to each data block that allow an error to be detected and corrected.

Hamming code H(7,4) works with 7-bit blocks: 4 data bits + 3 parity bits. Parameters: [n=7,k=4,d=3][n=7, k=4, d=3], where:

  • n=7n = 7 — total number of positions
  • k=4k = 4 — number of data positions
  • d=3d = 3minimum distance (minimum number of positions in which any two valid codewords differ)

Minimum distance d=3d = 3 means: the code can correct any single-bit error.

Why the Hamming analogy applies to Gap

The coincidence of the number 7 is not accidental: N=7N = 7 dimensions of the holon. The analogy with H(7,4):

  • 7 positions <-> 7 holon dimensions
  • 4 data positions <-> dimensions S, D, A, L (structure, drive, attention, language)
  • 3 parity positions <-> dimensions E, O, U (experience, ontology, unity)
  • Parity bits = non-zero Gap: provide detection of self-modelling mismatches
Theorem 5.1 (Hamming bound for Gap) [C]

Condition: G2G_2-structure, H(7,4) analogy. For any viable system at level L2 or above:

{(i,j):Gap(i,j)>0}3|\{(i,j) : \mathrm{Gap}(i,j) > 0\}| \geq 3

Argument. Hamming code H(7,4) has parameters [n=7,k=4,d=3][n=7, k=4, d=3]: 7 positions, 4 data, 3 parity. Minimum distance d=3d = 3 means the ability to correct a single-bit error. In the analogy:

  • 7 positions <-> 7 holon dimensions
  • 4 data positions <-> dimensions S, D, A, L
  • 3 parity positions <-> dimensions E, O, U
  • Parity bits -> non-zero Gap provides detection of self-modelling mismatches

If all 21 channels had Gap=0\mathrm{Gap} = 0, the system could not detect errors in self-modelling — φ\varphi would become the identity map and correction would be impossible. For more on the analogy: Hamming code in Gap dynamics.

What this means for L4

The Hamming bound makes L4 in its pure form (full transparency) physically impossible. Even in the ideal case (φ(Γ)=Γ\varphi(\Gamma^*) = \Gamma^*) at least 3 channels out of 21 must retain non-zero Gap. A system at "realistic L4" is not transparent — it is consciously opaque: it knows exactly where and why it has "blind spots", and uses them as control mechanisms.

8a. Quantitative examples: Gap profiles for L0--L4

Abstract Gap signatures become tangible when we consider concrete numerical matrices Γ\Gamma at each level. The following are characteristic representatives — not the only possible ones, but typical for each level.

Key difference from L0: Channel (E,S)(E,S) stands out sharply — Gap(E,S)=0.150.68\mathrm{Gap}(E,S) = 0.15 \ll 0.68. This is the first window through which the system "sees" the connection between experience and structure (chemotaxis: sensing a chemical gradient). The remaining channels are still opaque. Rank G^=3\hat{\mathcal{G}} = 3 or 22.

Four channels (E,A)(E,A), (E,S)(E,S), (E,D)(E,D), (E,L)(E,L) have low Gap — the system is aware of the connection between experience and attention, structure, dynamics, and language. Channels (E,O)(E,O) and (E,U)(E,U) are still partially opaque — deep reflection on meaning and unity is not yet complete. Rank G^=2\hat{\mathcal{G}} = 2.

All channels have low Gap. Even (E,O)(E,O) and (E,U)(E,U) — the system is aware of the connection between experience and the ontological ground and unity. The meta-Gap is defined: Gap(2)(E,S)0.01\mathrm{Gap}^{(2)}(E,S) \approx 0.01 — the system "knows that it knows". Rank G^=1\hat{\mathcal{G}} = 1.

Patterns:

  1. Opening cascade. Channels open in a definite order: first (E,S)(E,S) (L1), then (E,A)(E,A) and (E,L)(E,L) (L2), finally (E,O)(E,O) and (E,U)(E,U) (L3). This is not an arbitrary convention but a consequence of the structure of the reflexive loop φ\varphi.
  2. Mean and variance. At L0 the mean Gap is high, variance moderate (random spread). At L1 the mean may even increase (other channels compensate), but variance grows (structure appears). At L2--L3 both mean and variance fall.
  3. Rank decreases monotonically. 32321013 \to 2\text{--}3 \to 2 \to 1 \to 0\text{--}1 — the "number of walls" decreases at each level.

9. Gap injection of L-levels

Theorem (Gap injection of L-levels) [T]

The map from L-level to equivalence class of Gap profiles is an injection (but not a bijection):

L(Γ1)L(Γ2)    [Gap(Γ1)][Gap(Γ2)]L(\Gamma_1) \neq L(\Gamma_2) \implies [\mathrm{Gap}(\Gamma_1)] \neq [\mathrm{Gap}(\Gamma_2)]

Unique Gap markers of transitions:

TransitionGap markerSufficient condition
L0 vs L1i:Gap(E,i)>0\exists i: \mathrm{Gap}(E,i) > 0Non-zero E-coherences
L1 vs L2maxGapφGap2/3\max\|\mathrm{Gap}_\varphi - \mathrm{Gap}\| \leq 2/3Self-modelling accuracy
L2 vs L3Compression coefficient k(Γ)0.5k(\Gamma) \leq 0.5Speed of Gap convergence
L3 vs L4k(Γ)=0k(\Gamma) = 0, all Gap(2)(i,j)=0\mathrm{Gap}^{(2)}(i,j) = 0Exact fixed point

Full proof: Interiority hierarchy.

Injection, not bijection

The converse does not hold: two states Γ1,Γ2\Gamma_1, \Gamma_2 at the same L-level may have distinct Gap profiles (different "transparency maps"). The Gap profile is a finer invariant, carrying more information than the L-level. All Gap signatures (section 2) describe typical behaviour, not the only possible behaviour at a given level.

Analogy: the L-level is like the "floor" of a building, and the Gap profile is the detailed floor plan of the apartment on that floor. All apartments on the same floor are "at the same level", but layouts can differ.


What we have learned

  • Gap profile G(Γ)[0,1]21\mathbf{G}(\Gamma) \in [0,1]^{21} — quantitative fingerprint of the opacity of all 21 dimension pairs.
  • Gap signatures [C] distinguish levels: L0 (uniformly high Gap), L1 (partial transparency in E-sector), L2 (transparent A- and L-channels), L3 (recursive structure), L4 (full transparency with Hamming constraint).
  • E-sector channels play a special role: the first to open is (E,S)(E,S) (sensing structure), then (E,A)(E,A) and (E,L)(E,L) (attention and language).
  • Meta-Gap Gap(n)\mathrm{Gap}^{(n)} is defined for L3+: the Gap profile of the self-model, converging to the fixed point.
  • Hamming bound [C]: at least 3 channels out of 21 must retain Gap>0\mathrm{Gap} > 0 for fault tolerance (analogy with code H(7,4)H(7,4)).
  • Gap injection [T]: the map from L-level to Gap-profile class is injective but not bijective — Gap carries more information than the L-level.
What's next

Gap profiles describe the statics — the characteristic opacity pattern at each level. The dynamics of transitions between levels — how a system abruptly changes its Gap profile — are described by Transition catastrophes (A2,A3,A4A_2, A_3, A_4-bifurcations with hysteresis and critical slowing-down).

For diagnostic applications of Gap profiles see CC: bifurcations and predictions.
