HELLMANN-FEYNMAN MONOTONICITY argument REDONE on the CORPUS APS operator -- the
second of A334's two pre-registered fan-out probes, A335 (the second-preimage
scan) the sibling running in parallel).

Copyright Léon Fernando Vlegels -- CC BY 4.0

WHY THIS PROBE EXISTS. A332 ran the structural Hellmann-Feynman monotonicity
argument for sub-result (iii)'s free-weight coefficient injectivity. By
Hellmann-Feynman d lambda_n / d c_i = <psi_n|S_i|psi_n>, the diagonal matrix
element of sector S_i in the eigenbasis; a sector contributes MONOTONICALLY to
every eigenvalue iff its diagonal has a FIXED SIGN. A332 proved three of four
sectors sign-definite -- alpha*rho (rho>=0 multiplication, diagonal 116..181>0),
beta*M (M positive, diagonal in [0,1]>=0), gamma*Re(omega^k) (a rigid nonzero
shift, monotone per Z_3 character block) -- hence strictly monotone, hence
injective in (alpha,gamma,beta). The fourth, zeta*R with R=r d/dr, A332 found
NEAR-CONSTANT (<psi|R|psi> mean -2.000, relative spread 1.7e-4, cosine with the
uniform vector 1.00000): a near-uniform shift, the soft sector, the lone
obstruction. A333 then claimed zeta is an EXACT rigid shift (-2 for all modes),
upgrading A332's lone soft sector to the cleanest and completing four-sector
monotonicity.

But A332 and A333 built their radial operator on r=linspace(dr,1-dr,N-1) -- a
DIRICHLET wall at r=1 (psi(1)=0 by construction), NOT the corpus APS boundary
condition A329 established (P18 l.393-396), whose no-potential spectrum is the
integer ladder (2n+l+2)^2 (P18 l.171). A334 built the corpus APS operator
(R_nl=r^{-1}J_{l+1}(k r), k=2n+l+2, eigenstates that do NOT vanish at r=1,
psi_nl(1)=J_{l+1}(2n+l+2)!=0) and showed the zeta diagonal there is NOT the
near-uniform -2 of the Dirichlet model: under APS <psi_n|R_sym|psi_n> ranges
-1.98..+0.24, STATE-DEPENDENT and even SIGN-FLIPPING (l=2,n=0 gives +0.24). So
A332's monotonicity must be redone on the corpus APS operator -- which is the
job of THIS probe.

WHAT THIS PROBE DOES. It recomputes, on the corpus APS eigenstates (the A334
Bessel construction, with the hard gate that the no-potential spectrum is the
integer ladder (2n+l+2)^2, NOT squared-Bessel zeros), the Hellmann-Feynman
diagonal <psi_n|S_i|psi_n> for every sector, and re-checks sign-definiteness:

  S0  Bessel implementation cross-checked against known zeros            1-2
  S1  the corpus APS operator: spectrum=(2n+l+2)^2, psi(1)!=0 (gate)     3-4
  S2  alpha (rho-mult): <psi|rho|psi>>0 on APS states => MONOTONE        5-6
  S3  beta (M positive), gamma (Re(omega^k) rigid): MONOTONE on APS      7-8
  S4  zeta (R=r d/dr): the APS diagonal SIGN-FLIPS => NON-monotone       9-11
      + the alpha-zeta collinearity DROP (0.9986 Dirichlet -> ~0.66 APS) 12-13
  S5  what survives: 3 sectors monotone, zeta open; joint w/ A335       14-17

THE DECISIVE FINDING (the honest one). The three shape sectors STAY sign-definite
on the corpus APS eigenstates -- rho>=0 and M positive are STATE-INDEPENDENT
facts, and the Re(omega^k) shift is rigid, so their per-axis monotonicity transfers
to APS untouched. But the zeta diagonal <psi_n|R_sym|psi_n>=-2+(1/2)|psi(1)|^2/
<psi|psi> is NOT sign-definite on the corpus operator: it ranges from -1.98 to
+0.24 across modes and CHANGES SIGN of d lambda_n / d zeta (most modes lower,
the l=2 n=0 mode RAISES). So some eigenvalues rise and others fall as zeta
increases -- per-axis monotonicity in zeta FAILS under the corpus boundary
condition. A333's "four-sector monotonicity complete" is a DIRICHLET ARTIFACT;
it does NOT transfer.

WHAT SURVIVES. Per-axis injectivity for (alpha,gamma,beta) by structural
monotonicity, transferred to APS. zeta injectivity is NOT provable by
monotonicity -- the diagonal is sign-indefinite -- so the analytic global proof
at the zeta sector is genuinely OPEN under the corpus boundary condition (NOT
closed as A333 claimed). The honest joint picture WITH A335 (the sibling): A335
found in-box global injectivity SURVIVES on the corpus APS operator with a LARGER
moat (the state-dependent zeta diagonal STIFFENS the landscape, breaking the
alpha-zeta degeneracy that made the Dirichlet valley flat). So (alpha,gamma,beta)
are analytically injective + zeta injectivity rests on A335's in-box numerics; the
analytic global proof at the zeta sector stays OPEN under the corpus BC.

VERDICT: PARTIAL + REFUTATION. Three-sector monotonicity TRANSFERS to APS; zeta
monotonicity FAILS (the APS zeta diagonal is sign-indefinite, sign-flipping at
l=2 n=0); A333's four-sector-monotonicity HIT is overturned on the corpus
operator; the analytic zeta-injectivity gap is REAL under the corpus BC, closed
only numerically and in-box by A335; the corpus tie zeta=alpha^{5/4} remains the
clean closure for the corpus-posed family. Honesty over closure -- we report the
failure of zeta-monotonicity, not a forced transfer.
