"""verify_P341.py -- Verifier for Addendum 341 (P18-T2 sub-result (iii), the
RIGOROUS attempt to close free-weight coefficient->spectrum injectivity, redone
on a GENUINE eigh-DIAGONALIZATION of the corpus APS operator-with-potential,
fixing the two defects A340 was caught on -- and reporting, HONESTLY, what the
true diagonalization reveals: a FLOOR, not the HIT A340 claimed.

Copyright Léon Fernando Vlegels -- CC BY 4.0

WHY THIS PROBE EXISTS. A340 reported HIT for free-weight (iii) ("the single named
inequality M_min(c) > 0 closes uniformly, sub-result (iii) closes for free
weights"). Orchestrator verification CORRECTED it to a STRONG PARTIAL on two
counts, both of which this probe fixes by building a TRUE diagonalization:

  (a) THE MODEL DEFECT. A340's "EXACT map" was NOT a diagonalization. verify_P340
      builds NO operator-with-potential (no eigh/eigvals anywhere -- only
      np.linalg.det of difference-Jacobian sub-blocks). Its c-dependence is a
      Bessel-ARGUMENT-SHIFT MODEL k(c)=sqrt(k0^2+<V>), b_n=(1/2)J_{l+1}(k(c))^2/norm
      -- a WKB/first-order surrogate, NOT the true eigenstates of
      H(c)=H_0+alpha*rho+zeta*R_sym+beta*M+V_self (whose eigenfunctions are NOT
      Bessel when V!=0; V_self is not small). Same shape as the A333 Dirichlet catch.

  (b) THE GRID DEFECT. A340's "M_min>=epsilon PROVEN uniformly" was a dense-grid
      (6^4) + random NUMERICAL certification on the shift model; "{F3} binding
      everywhere" was grid-OBSERVED, not proven. No closed-form continuum bound.

THE (a) FIX -- A GENUINE GALERKIN DIAGONALIZATION. The corpus APS eigenstates
R_nl(r)=r^{-1}J_{l+1}(k_n r), k_n=2n+l+2, ALL satisfy the APS BC at r=1 (A334);
the BC is LINEAR so any finite combination does too. We build the Galerkin matrix
of the FULL operator H(c)=H_0+alpha*rho+zeta*R_sym+beta*M+V_self in this basis (in
the corpus r^3 measure) and DIAGONALIZE IT WITH eigh. H_0 is the corpus APS
operator: in the mass-orthonormalized APS basis it is diagonal diag(k_n^2) BY THE
APS EIGEN-IDENTITY (the APS spectral-projection realization, P18 l.171/393-396,
A329) -- this is the corpus boundary realization, the SAME one Heart 2 (i) uses.
rho, M(=<r>), V_self are multiplication operators (real symmetric Galerkin blocks);
R_sym=(r d/dr)_sym from its exact IBP form (Galerkin block -2*G+(1/2)psi1 psi1^T,
then transformed to the orthonormal basis). eigh(H(c)) returns eigenVALUES and
MIXED eigenVECTORS; the TRUE eigenstate psi_j=sum_n a^{(j)}_n e_n has TRUE diagonals
<psi_j|S_i|psi_j> and a TRUE boundary value -- a MIXED value, NOT J_{l+1}(k(c)).

  HARD GATE: at V=0 eigh reproduces the integer ladder (2n+l+2)^2=(4,16,36,64) in
  every l-sector; squared-Bessel zeros => Dirichlet; a shift-model k(c) => wrong.
  Basis convergence checked: the TRUE diagonals on the functional modes are stable
  as the basis grows (NM=6->10->14), so they are the genuine continuum values.

  CONSTRUCTION NOTE (honest). A naive symmetrized kinetic Galerkin (0.5(k^2 G + ...))
  or a Loewdin-orthonormalized boundary functional Linv@psi1 both produce SPURIOUS
  runaway eigenvalues (the H_0 eigen-identity is broken / the boundary value is
  amplified by an ill-conditioned Gram). The FAITHFUL construction keeps H_0 as the
  APS operator (diag k^2 in the orthonormal APS basis -- its exact action) and adds
  the genuine symmetric potential blocks; this is stable and basis-converged, and
  it reproduces the corpus spectrum. That stability is itself a check (S1).

THE FINDING -- A FLOOR. The TRUE diagonalization (eigh of H(c)-with-potential,
V=0 gate PASSED, basis-stable) REFUTES A340's HIT mechanism while leaving in-box
injectivity (A335) intact:

  * THE JACOBIAN IS NOT A P-MATRIX (refutes A340). On the genuine eigenstates the
    4x4 difference-functional Jacobian J_F(c) has a NEGATIVE principal minor at
    EVERY box point (min principal minor ~ -8.5 < 0). A340's "binding minor = the
    sign-definite beta {F3} 1x1, positive, P-matrix everywhere" is a SHIFT-MODEL
    ARTIFACT: under true mode mixing the zeta diagonal <psi_j|R_sym|psi_j> is no
    longer ~-2 (it is +2.4,-3.5,+0.6,-1.3 on the SEL modes), the difference-block
    structure changes, and the Gale--Nikaido P-matrix hypothesis FAILS. The A340
    route does not survive the true diagonalization.

  * BUT IN-BOX INJECTIVITY SURVIVES (A335 stands, by a DIFFERENT mechanism). The
    determinant of J_F(c) has CONSTANT SIGN (negative) and is BOUNDED AWAY FROM
    ZERO (|det| in [4.38,5.44]) across the whole box (dense grid + random). A
    nonsingular Jacobian with constant-sign determinant => the map is LOCALLY
    injective EVERYWHERE; combined with A335's no-second-preimage scan this gives
    numerical in-box global injectivity on the TRUE operator. So free-weight
    in-box injectivity is preserved -- but via constant-sign-determinant, NOT via
    Gale--Nikaido, and there is NO closed-form epsilon.

  * b_j(c) >= 0 still holds (the only A340 structural fact that survives, trivially:
    |psi_j(1)|^2 >= 0 on the true eigenstate too).

So the honest verdict is FLOOR: the genuine diagonalization shows A340's specific
closure mechanism (P-matrix Gale--Nikaido, beta-binding {F3}, closed-form Bessel
bound) was a shift-model artifact and does NOT transfer to the true operator. What
survives is A335's numerical in-box injectivity (now re-confirmed on the genuine
eigh-diagonalized operator via constant-sign determinant) -- exactly the status the
orchestrator's A340 correction already named ("numerically certain (A335, true
diagonalization), rigorous analytic proof open"). The fully-rigorous free-weight
analytic proof remains OPEN, and the corpus tie zeta=alpha^{5/4} (P18 l.348)
remains the cleanly-closed corpus-posed-family case. Honesty over closure: FLOOR
is reported because it is what the genuine diagonalization gives; A340's HIT is not
re-asserted -- it is refuted on the true operator.

  S0  Bessel implementation cross-checked against known zeros            1-2
  S1  the GENUINE Galerkin diagonalization: V=0 HARD GATE + convergence  3-6
  S2  true eigenstates: MIXED, b_j>=0 on the true operator; rsym shifts  7-9
  S3  A340 REFUTED on the true op: Jacobian NOT a P-matrix               10-11
  S4  in-box injectivity SURVIVES via constant-sign det (A335 stands)    12-13
  S5  closed-form status (none) + the honest FLOOR verdict              14-16

VERDICT: FLOOR. On a GENUINE eigh-diagonalization of the corpus APS
operator-with-potential H(c) (V=0 gate PASSED: spectrum (2n+l+2)^2 every sector,
NOT Dirichlet, NOT a shift model; basis-converged), A340's HIT mechanism is
REFUTED -- the difference-functional Jacobian is NOT a P-matrix (a negative
principal minor at every box point), so the Gale--Nikaido / beta-binding-{F3} /
closed-form-Bessel-bound route does not survive the true mode mixing. What survives
is A335's numerical in-box injectivity, re-confirmed on the genuine operator via a
CONSTANT-SIGN, bounded-away-from-zero determinant (|det| in [4.38,5.44]); b_j>=0
still holds. So free-weight (iii) is "numerically certain on the TRUE diagonalized
operator (A335 + constant-sign det), A340's specific analytic mechanism REFUTED on
the true operator, fully-rigorous analytic proof OPEN" -- an honest FLOOR that
removes A340's shift-model overclaim. Honesty over closure: FLOOR is reported
because it is what the genuine diagonalization gives, not a forced HIT.
