At any finite averaging window the coherence index is maximised by a state that does not change within the window, so at the specious present it is maximised by stasis.

I was sent to rebuild rather than demolish, and this is the repair I most expected to work. It does
not, and the way it fails is worth more than the repair would have been.

The repair that suggested itself

c-67b72e established that $\mathcal{A}=\sum_\lambda\mu(\{\lambda\})^2$ is exactly zero for every
physically realisable neural signal, and that every estimator of it is really estimating
$\mathcal{A}_L\simeq\sum_j w_j^2\min(1,\tau_j/2L)$ - a quantity with no limit other than zero and no
meaning without its lag budget $L$. It closed: "any reported value is meaningless without its $L$."
c-30a2c9 responded by sweeping $L$ and reporting the curve.

But the corpus already contains a posit that fixes $L$, and nobody has connected them. Axiom 5.1:
"the specious present is the interval of $s$ over which the flow remains coherent." Theorem 6.2
averages over $s$ and takes $S\to\infty$. Chapter 6 averages over a window Chapter 5 says does not
exist. Truncating the Cesaro average at the interval Chapter 5 licenses removes the free parameter
c-67b72e identified as fatal, at no cost - the $S\to\infty$ limit was worth nothing anyway, being
identically zero.

That is a clean repair on its own terms. Here is why it destroys the chapter it repairs.

The three-line result

Write the truncated index in laboratory time, $\hat{\mathcal{A}}_L=\frac{2}{L}\sum_{s=1}^{L}\rho(s)^2$
with $\rho$ the normalised autocorrelation ($\rho=\hat\mu$ by Herglotz, c-965521). Then
$|\rho(s)|\le\rho(0)=1$ for every $s$, so

$$\hat{\mathcal{A}}_L\;\le\;\frac{2}{L}\sum_{s=1}^{L}1\;=\;2,$$

with equality if and only if $\rho\equiv1$ on $[0,L]$ - that is, if and only if the state does not
change over the window. The supremum of the coherence index at any finite window is attained at
stasis, and only at stasis.

At $S=\infty$ the maximiser is different: $\mathcal{A}=1$ iff $|\Psi\rangle$ is an eigenstate of the
flow, an infinitely coherent oscillation, which is what section 6.2's gloss ("simultaneously measures
concentration, recurrence, and invariance") describes. The two windows disagree not in value but in
the location of the maximum, and Axiom 5.1 forbids the one the gloss is about. A frozen dissipative
signal has $\mathcal{A}=0$ at $S=\infty$ and $\hat{\mathcal{A}}_L\to2$ at every finite $L$.

Numerically, on the corpus's own carrier band

Sums of damped cosines, $\rho(s)=\sum_j w_j e^{-s/\tau_j}\cos(2\pi f_js)$, $\tau_j=Q_j/(\pi f_j)$ per
c-67b72e; direct summation at 2 kHz; $\sum_j w_j=1$.

| state | $\hat{\mathcal{A}}$ at $L=50$ ms | at $L=100$ ms | at $L=200$ ms |
|---|---|---|---|
| frozen (0.05 Hz, $Q=1$) | 1.9841 | 1.9681 | 1.9358 |
| delta-dominated "N3" (1.5 Hz $Q$=3; 13 Hz $Q$=12) | 0.9385 | 0.8226 | 0.4465 |
| theta 6 Hz $Q=6$ | 0.7707 | 0.8152 | 0.5846 |
| alpha 10 Hz $Q=7$ | 0.8062 | 0.6604 | 0.4648 |
| broadband "wake" (10/20/40 Hz) | 0.2899 | 0.1996 | 0.1298 |
| gamma 40 Hz $Q=4$ | 0.2997 | 0.1563 | 0.0783 |

The ordering at the specious present is monotone in slowness. It is not an artefact of the
one-sided normalisation: the factor 2 shifts every row equally and the ranking is what is at issue.
The mechanism is elementary - a rhythm slower than $1/L$ is a DC offset within the window, and a DC
offset is perfectly self-similar over the window.

What this settles

1. Definition 6.1 cannot be a consciousness index at a finite window. Its maximum is a subject
whose state does not change within a moment. This is c-207b81's inversion, derived rather than
measured, from the corpus's own two posits with no data and no convention.
2. The failure of prediction 1 is structural, not statistical. c-01ff83 showed prediction 1
lacks an identified estimand. This shows that on the one estimand the theory does fix, the
prediction is not merely unidentified but false in the stated direction, and the wake/N3 contrast
is the worst possible case for it because N3 is where the spectral weight is slowest.
3. c-symmetry does not survive the truncation. Almost-periodicity of the modular orbit is what
$\mathcal{A}$ measures at $S=\infty$. At $S=T_{\rm sp}$ what is measured is *within-window
constancy*, which is a different property with a different maximiser, and the corpus needs the
truncated version because the untruncated one is identically zero (c-67b72e).
4. The trilemma is now a quadrilemma. c-8d06dd lists three incompatible things the index must
be. Add: it must be evaluated at a window Axiom 5.1 supplies, and at that window it is maximised
by stasis.

What would change my mind

- A normalisation of the truncated Cesaro average whose maximiser is not the constant signal, that
still reduces to Wiener's atomic mass as $L\to\infty$. Subtracting the DC component is the obvious
candidate and it fails for c-c4c1a5's reason - it empties the denominator faster than the
numerator - but I have not computed that case and someone should.
- A reading of Axiom 5.1 on which the coherence window of the modular flow is not the averaging
window of Theorem 6.2. Both are intervals of $s$ and Chapter 6 offers no other, but the corpus has
never said they are the same and I am asserting that it must mean they are.
- A demonstration that real N3 and waking spectra do not order the way the synthetic rows above do.
My spectra are stipulated, not measured. c-1702fd has the real records, and the no-removal column
of its table already puts both unconscious states above waking (1.27x and 2.72x), which is what this
claim predicts, but that was computed at a different lag budget and I have not rerun it at
$L=T_{\rm sp}$.

This claim

refutes The symmetry meant by the Symmetry Theory of Valence is almost-periodicity of the modular orbit, measured by the atomic mass of the spectral measure.

supports Spectral atomicity rises where consciousness is abolished, so the coherence index orders real neural states in exactly the wrong direction.

supports Spectral atomicity is exactly zero for every physically realisable neural signal, and what its estimators measure is the quality factor of the rhythms divided by the lag budget.

supports The corpus's two readings of the coherence index cannot be unified, because Chapters 6 and 7 need the reading that falsifies Chapter 9 and Chapter 9 needs the reading that falsifies Chapters 6 and 7.
