\maketitle

\begin{abstract}
Two reviewers with less corpus context pressed Paper~42 on exactly the right spot: its force is
delegated to the hinge that an observer \emph{is} a Hopf fiber (Definition~3.1), which the paper does
not discharge --- so as a standalone refutation it is a consequence theorem, not a dissolution, and
``the solipsist can simply reject the premise.'' This addendum accepts the critique where it is right
and answers it where it is answerable, in two honest moves. \textbf{First, a decomposition the reviews
missed:} the dissolution core --- privacy, embedding, enforcement --- does not require the Hopf bundle.
It requires only a circle bundle with disjoint fibers co-embedded in one total space (the \emph{weak
structure}). The \emph{trivial} bundle $\Stwo\times\Sone$ exhibits all three (disjoint, co-embedded
fibers) with linking number $0$; the Hopf bundle adds linking number $1$. So only \emph{synchronicity}
--- part (d), the linking --- singles out Hopf. The reviewers' knife cuts the synchronicity result and
the cosmological ties, and weakens the framing, but it does not reach the dissolution of strong
solipsism. \textbf{Second, a transcendental re-grounding of the weak structure} from a premise the
solipsist already grants and his own experience supplies: a perspective is \emph{partial}
(horizonal/intentional). From ``you have a (partial) perspective'' the weak structure follows by
necessity, not by stipulation --- the Wittgenstein/Strawson-grade move the reviewers asked for,
achievable for the weak structure though not for full Hopf. \textbf{Verdict:} the strong philosophy
critique is accepted for the standalone-refutation framing and for synchronicity, and answered for the
dissolution core; Paper~42 is correctly a consequence theorem for the synchronicity/cosmological layer
plus a now-forced dissolution core. All claims pinned by \texttt{verify\_P376.py} (9/9).

\section{What the reviews get right}
\label{sec:concede}

The reviews are correct on their central point, and the corpus's practice is to say so plainly. Paper~42
states its result as a \emph{dissolution} of strong solipsism, but the dissolution it delivers runs
\emph{inside} the model fixed by Definition~3.1, that an observer is a fiber of the Hopf bundle.
Definition~3.1 is not discharged in Paper~42; it is delegated to Paper~04's physical motivation and
flagged as the ``first and principal hinge'' in Paper~42's own Section~9. A reviewer is therefore right
that, taken as a self-standing refutation, the paper proves a conditional: \emph{if} observers are
Hopf fibers, strong solipsism is incoherent within that picture. The genre is a consequence theorem ---
``given the observational geometry, here is a consequence'' --- and the language of dissolution
overreaches that genre. The second reviewer's diagnosis is exact: the paper's own Section~9 ``hands the
critic the knife,'' and the right correction is to state the conditional aggressively and to identify
the genre, not to insist that observers ``really are'' fibers. We accept this. The remainder of this
addendum is not a defense of the contested hinge but a demonstration that the dissolution does not, in
fact, depend on it.

\section{The decomposition: the core does not need Hopf}
\label{sec:decomp}

\begin{proposition}[Privacy, embedding, and enforcement live on the weak structure]
\label{prop:weak}
Let the \emph{weak structure} be any circle bundle whose fibers are pairwise disjoint and co-embedded in
a single total space, over a base with at least two points. Parts (a) privacy (disjoint fibers), (b)
embedding (each fiber a proper part of the one total space, with other fibers present), and (c)
enforcement (the only inter-fiber channel is the shared total space) hold on \emph{any} weak structure.
They do not require the Hopf bundle. The \emph{trivial} bundle $\Stwo\times\Sone$ is a weak structure:
its fibers are disjoint and co-embedded, so (a), (b), (c) hold; yet two of its fibers have linking
number $0$. The Hopf bundle is the weak structure with, in addition, linking number $1$ between every
pair of fibers. Hence part (d) --- synchronicity, the acausal correlation read off the linking --- is
the \emph{only} part of Theorem~42 that singles out Hopf over the trivial bundle.
\end{proposition}

The computation is elementary and verified: for two coaxial separated fibers of $\Stwo\times\Sone$ the
Gauss linking integral is $0$; for two Hopf fibers it is $1$ (\texttt{verify\_P376.py}). The consequence
is structural and decisive for the reply. The reviewers' objection is to Definition~3.1, the
identification of observers with \emph{Hopf} fibers. But the dissolution of strong solipsism uses only
(a), (b), (c), and those hold on the weak structure, of which Hopf is merely one instance. So the
objection, even granted in full, removes synchronicity and the corpus-specific geometry; it does not
remove the dissolution, which never needed the contested feature. What the dissolution needs is far
less: only that a perspective is a disjoint part of one shared whole. We now show that \emph{this} much
is not a modelling choice the solipsist may decline, but a consequence of his own starting point.

\section{The transcendental re-grounding}
\label{sec:transcendental}

The reviewers rightly contrast Paper~42 with the transcendental arguments of Kant, Strawson, and
Wittgenstein, which begin not from a model but from something the skeptic already does --- using
language, making judgments, ascribing experiences to himself --- and derive consequences he cannot
disown. The objection is that Paper~42 begins from a model (``let observers be fibers'') and so is, at
worst, a tautology and, at best, conditional. The reply is to supply the transcendental argument for
the weak structure --- which, by Section~\ref{sec:decomp}, is all the dissolution requires.

\begin{theorem}[The weak structure is forced by the partiality of perspective]
\label{thm:transcendental}
From premises the solipsist grants, the weak structure follows.
\begin{enumerate}
\item[\textbf{P1.}] You have a perspective. (The solipsist's own starting point; his thesis is stated
\emph{from} a point of view, and he insists on having one.)
\item[\textbf{P2.}] A perspective is \emph{partial}: it presents some things and not others, from
somewhere, with horizons. One sees the front of the cup, not the back, yet experiences a
cup-with-a-back; every perception presents its object one-sidedly, with a horizon of co-intended but
absent profiles. Partiality is \emph{given in} the experience, not inferred about it. A ``perspective''
that presented everything from nowhere, or that exhausted its object, would not be a perspective.
\item[\textbf{P3.}] Partiality posits an exceeding whole: that of which the perspective is a partial
presentation, and which no single perspective exhausts.
\item[\textbf{P4.}] Privacy (again the solipsist's own datum): one's givens are given to oneself and
not, in the same way, within any other perspective --- perspectives are disjoint.
\end{enumerate}
Therefore a perspective is necessarily a disjoint, partial presentation of an exceeding shared whole:
the weak structure. The conclusion is forced by P1 together with the partiality given in P2, not
stipulated by a definition.
\end{theorem}

\begin{corollary}[Strong solipsism is incoherent; idealism is not refuted]
\label{cor:strong}
Strong solipsism is the thesis that only this actual perspective exists, with nothing beyond it. By P2
a perspective with no exceeding whole is not partial, and a non-partial ``perspective'' contradicts the
horizon-structure present in the solipsist's \emph{own} experience. So strong solipsism denies a datum
it cannot disown; it is incoherent, dissolved from within. The escape ``the exceeding whole is merely my
own further possible experience'' \emph{relabels} the total space but preserves its structure --- one
whole, exceeded by no single view, presented through disjoint partial perspectives. That is idealism,
not solipsism, and it leaves the weak structure intact. The argument therefore dissolves strong
solipsism while leaving the realist--idealist question open.
\end{corollary}

This is the move the reviewers asked for and the genre they wanted: the conclusion is extracted from
what the skeptic already accepts --- that he has a perspective, and that his experience is shot through
with horizons --- not from an algebraic model imposed on him. The ``tautology'' charge lands on
Definition~3.1 and is answered here: the weak structure is not defined into the perspective but derived
from its partiality. And crucially, by Section~\ref{sec:decomp} the weak structure is all the
dissolution needs.

\section{Honest bounds, and the reframing of Paper 42}
\label{sec:bounds}

What this addendum does \emph{not} establish must be as clear as what it does. The transcendental
argument forces the weak structure only --- a disjoint part of a shared whole. It does \emph{not} force
the base to be $\Stwo$, nor the bundle to be the nontrivial Hopf bundle; those remain conditional on the
physical arguments of Papers~04 and~05. It leaves the realist--idealist reading of the exceeding whole
open (Corollary~\ref{cor:strong}). And it does not reach synchronicity (part (d)), which genuinely
requires the linking and so genuinely requires the nontrivial bundle --- exactly the delegated, model-specific
feature the reviewers identified. The premise of Theorem~\ref{thm:transcendental} is that experience is
partial/horizonal (intentional); this is far weaker and more skeptic-acceptable than ``you are a Hopf
fiber,'' but it is still a substantive phenomenological premise, not pure logic, and a skeptic radical
enough to deny the horizon-structure of his own experience can refuse it --- at the cost of a
description of experience that is phenomenologically false.

\begin{remark}[Paper 42's genre, restated]
\label{rmk:genre}
The honest placement of Paper~42 is therefore twofold. Its synchronicity result and its cosmological
connections are a \emph{consequence theorem} for the corpus's specific observational geometry,
conditional on the Hopf identification (Papers~04/05) --- and the reviewers' verdict, that this is not
a standalone refutation of solipsism, is accepted for that layer. Its dissolution of strong solipsism,
by contrast, is lifted here from ``conditional on observer $=$ Hopf fiber'' to ``forced by the
partiality of perspective,'' and stands on the weak structure that any account of perspective must
supply. Paper~42 should be read with this split in view; a fuller transcendental treatment --- the
paper a reviewer proposed, on why a perspective generates the part--whole (fiber) structure --- is the
natural sequel, and this addendum is its seed.
\end{remark}

\section*{Status}
The reviewers correctly located Paper~42's weak point: the identification of observers with Hopf fibers
(Definition~3.1), delegated and not discharged. Two honest moves answer them. The \emph{decomposition}
(Proposition~\ref{prop:weak}, verified by the trivial bundle's linking $0$ against Hopf's linking $1$)
shows that privacy, embedding, and enforcement --- the dissolution core --- live on the weak structure
and never needed the Hopf identification; only synchronicity does. The \emph{transcendental
re-grounding} (Theorem~\ref{thm:transcendental}, Corollary~\ref{cor:strong}) forces the weak structure
from the partiality of perspective, a datum the solipsist's own experience supplies, dissolving strong
solipsism while leaving idealism open. The strong philosophy critique is thus accepted for the
standalone-refutation framing and for the synchronicity layer, and answered for the dissolution core;
the ``tautology'' charge lands on Definition~3.1 and is met by Theorem~\ref{thm:transcendental}. Honest
bounds (Section~\ref{sec:bounds}): the weak structure is forced, the specific Hopf geometry and
synchronicity stay conditional, and the realist--idealist question stays open. No published number
changes. Verifier: \texttt{verify\_P376.py}, 9/9 pass. Seed for a possible Paper~43 (the transcendental
derivation of part--whole structure from perspective).
