"""verify_P373.py -- Verifier for Addendum 373 (shared reality enforced: the Hopf fibration makes
intersubjective consistency a THEOREM, observation-free -- one shared S^3, disjoint fibers, the only
inter-fiber channel through S^3 -- peeling the enforcement from the consciousness reading, a la 372,
and tightening the 370/372 shared-arena residual).

WHY THIS PROBE EXISTS. P04 proves "Multiple Observers on Shared Boundary" (all S^1 monad-fibers thread
one S^3) with the corollary "Objective Reality from Shared Boundary: the shared topology ENFORCES
consistency," and "Communication via Classical Layer" (disjoint fibers, M_i -> S^3 -> M_j). The
content "shared reality is enforced" is therefore in canon -- but bundled with the consciousness
reading (monad = observer). This probe peels them (as 372 peeled gravity=self-lensing from
self-lensing=observation) and asks: is the ENFORCEMENT a theorem independent of the reading, and what
does it do to the 370/372 residual (the existence of ONE shared arena/breath map)?

THE PEEL (each rung with status).
  E1 [P04/Hopf, THEOREM, observation-FREE]. The Hopf fibration pi: S^3 -> S^2 has ONE total space
     S^3; every fiber pi^{-1}(q)=S^1 lies in that one S^3. So there is a SINGLE shared boundary -- no
     two disjoint S^3's, no private arena. Pure fiber-bundle topology; no consciousness reading.
  E2 [P04/Hopf, THEOREM]. Distinct fibers are DISJOINT: M_i cap M_j = empty (i != j). Two points of
     S^3 lie in the same fiber iff they differ by a global phase e^{i theta}; over distinct base
     points the fibers never meet. Privacy (fiber-local views) is real and enforced.
  E3 [P04, THEOREM]. Because fibers are disjoint (E2) yet co-embedded in one S^3 (E1), the ONLY
     inter-fiber channel is the shared S^3: M_i -> S^3 -> M_j. Consistency/communication is enforced
     THROUGH the common classical layer; solipsism (a fiber in some other arena) is topologically
     excluded. This IS "the shared topology enforces consistency" (P04 corollary).
  INT [P04, interpretation, same flag as 372]. That the threads ARE conscious observers
     (monad = consciousness) is the reading P04 carries as interpretation, not theorem.

CONSEQUENCE FOR 370/372. 370/372 left the EXISTENCE of one shared arena (a single breath map that all
mass couples through) inside the interpretive residual. E1-E3 make the UNIQUENESS/SHAREDNESS of the
arena theorem-grade: there is ONE S^3 (one classical boundary, hence one breath rhythm / one global
H_0), Hopf-enforced. So "there is a single shared reality, and it is enforced" is a THEOREM; only the
monad=observer identification stays interpretive (plus, from 372, the coupling MAGNITUDE a0, refuted/
typed). The shared-arena part of the residual moves from interpretation to theorem. H_0 unchanged.

WHAT THIS VERIFIER ESTABLISHES (Hopf arithmetic + bookkeeping):
  S0  E1: all Hopf fibers lie in ONE S^3 (unit-norm in C^2); one total space, one shared boundary    1-2
  S1  E2: fibers over distinct base points are DISJOINT (min separation > 0); same fiber = global ph  3-4
  S2  E3: only inter-fiber channel is through S^3 -> consistency enforced, solipsism excluded         5-6
  S3  peel: enforcement (E1-E3) is observation-FREE topology; monad=observer is the interpretation    7
  S4  consequence: uniqueness of the arena is theorem-grade -> tightens 370/372; H_0=75.8 unchanged   8-9

VERDICT: "shared reality enforced" is a THEOREM and observation-free -- the Hopf fibration forces one
shared S^3 (E1), disjoint fibers (E2, privacy), and the sole inter-fiber channel through S^3 (E3,
consistency enforced, solipsism excluded). Privacy and sharedness are TWO FACES of one topological
fact (disjoint fibers co-embedded in one bundle). Only the monad=observer identification is
interpretation (the 372 flag). The yield for 370/372: the UNIQUENESS of the shared arena -- one S^3,
one breath map, one global H_0 -- is theorem-grade, so "there is a single shared reality and it is
enforced" moves from interpretation to theorem; what stays interpretive narrows to the observer
identification (and the 372 magnitude floor). H_0 = 2 alpha^2 / T_breath = 75.8 is unchanged: a
tightening, not a re-derivation.
