"""verify_P376.py -- Verifier for Addendum 376 (reviewer response to Paper 42: the dissolution core
needs only the WEAK structure (a disjoint part of one shared whole), not the full 'observer = Hopf
fiber' identification; only synchronicity needs Hopf. And the weak structure is transcendentally
forced from the PARTIALITY of perspective -- a datum the solipsist's own experience supplies --
answering the 'tautology / you just defined it so' charge).

WHY THIS PROBE EXISTS. Two reviewers (less corpus context) pressed Paper 42 on exactly the right
spot: its force is delegated to the hinge 'an observer IS a Hopf fiber' (Def 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' (the model-theoretic, possibly tautological, move).
This addendum responds in two honest steps -- a decomposition the reviewers missed, and a
re-grounding of the part that matters on a premise the skeptic cannot disavow.

STEP 1 -- THE DECOMPOSITION (checkable). The anti-solipsism CORE -- (a) privacy, (b) embedding, (c)
enforcement -- does NOT require the Hopf bundle. It requires only a circle bundle with disjoint fibers
co-embedded in ONE total space (the WEAK structure). Demonstration: the TRIVIAL bundle S^2 x S^1 has
disjoint, co-embedded fibers (privacy + embedding + enforcement all hold) but linking number 0; the
HOPF bundle has linking number 1. So (a),(b),(c) hold on BOTH bundles; only (d) SYNCHRONICITY (the
linking) singles out Hopf. Consequence: the reviewers' knife (the Hopf identification) cuts the
synchronicity result and the cosmological ties, and weakens the FRAMING, but it does not reach the
dissolution of strong solipsism, which lives on the weak structure.

STEP 2 -- THE TRANSCENDENTAL RE-GROUNDING (philosophical; flagged). The weak structure is forced from
a premise the solipsist already grants and his own experience supplies: a perspective is PARTIAL
(horizonal/intentional). 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 absent profiles
(Husserl). Partiality is GIVEN in the experience, not inferred. Then:
  P1  You have a perspective (the solipsist's own starting point; he insists on it).
  P2  A perspective is partial: it presents some things, from somewhere, with horizons -- a
      partial presentation of what exceeds the presentation. (A 'perspective' on nothing, or one that
      exhausted its object, is not a perspective. Datum, not stipulation.)
  P3  Partiality posits an exceeding whole: that of which the perspective is a partial presentation,
      which no single perspective exhausts.
  P4  Privacy (the solipsist's own datum): one's givens are given to oneself and not, in the same
      way, to any other perspective -> perspectives are DISJOINT.
  C   Therefore a perspective is necessarily a disjoint, partial presentation of an exceeding shared
      whole = the WEAK structure (disjoint part of one total space). Forced from P1 + the given
      partiality, NOT from 'let observers be fibers'. This is the Wittgenstein/Strawson-grade move
      the reviewers asked for, achievable for the weak structure though not for full Hopf.
The solipsist's escape 'the exceeding whole is just MY further possible experience' RELABELS the
total space but keeps its structure (one whole, many disjoint partial views) -- that is IDEALISM, not
solipsism, and it leaves the weak structure intact. STRONG solipsism ('only this actual perspective
exists, nothing beyond') is refuted by P2: a perspective with no exceeding whole is not partial, and
a non-partial 'perspective' contradicts the horizon-structure given in the solipsist's own experience.

HONEST BOUNDS (what stays conditional). (i) The argument forces the WEAK structure, NOT the specific
Hopf geometry (base = S^2, the NONtrivial bundle); those stay conditional on Paper 04/05's physics.
(ii) It leaves the realist-vs-idealist reading of the exceeding whole OPEN (idealism survives). (iii)
Synchronicity (d) genuinely needs the nontrivial bundle and stays delegated. (iv) The transcendental
premise is now 'experience is partial/horizonal (intentional)', far weaker and more skeptic-acceptable
than 'you are a Hopf fiber', but still a substantive phenomenological premise, not pure logic.

NET. Paper 42 is correctly reframed as a CONSEQUENCE THEOREM for the synchronicity/cosmological layer,
PLUS a dissolution core that this addendum lifts from 'conditional on observer=Hopf-fiber' to 'forced
by the partiality of perspective'. The reviewers' 'tautology' charge lands on the stipulative Def 3.1
and is answered by the derived grounding here; their verdict 'fatal to the paper as a standalone
refutation' is ACCEPTED for the synchronicity-laden version and ANSWERED for the core.

WHAT THIS VERIFIER ESTABLISHES (linking arithmetic + the argument's bookkeeping):
  S0  trivial bundle: disjoint+co-embedded fibers, linking 0 -> (a,b,c) hold WITHOUT Hopf            1-2
  S1  Hopf bundle: linking 1 -> only (d) synchronicity singles out Hopf (the decomposition)          3
  S2  transcendental core: partiality (given) -> exceeding whole; privacy -> disjoint -> weak struct  4-5
  S3  strong solipsism refuted by P2; idealism survives (relabels the whole); honest bounds          6-7
  S4  net: core lifted conditional->forced; synchronicity stays conditional; genre reframed           8-9
