"""verify_P349b.py -- Verifier for Addendum 349b (P18-T2, sub-result (a):
each named component R_i is the only operator in its category).

Copyright Leon Fernando Vlegels -- CC BY 4.0

WHY THIS PROBE EXISTS. P18 sec.4.4 records that a proof of assembly uniqueness
(P18-T2) requires THREE independent sub-results: (a) each R_i's named operator is
the only operator in its category; (b) additive composition is the only admissible
composition; (c) the four coefficients are the only spectrum-matching assignment.
The b-thread 345b-348b worked (c) and reduced it to one named Schur scalar. This
addendum works (a): the component-by-component uniqueness audit. It does NOT prove
full uniqueness; it CLASSIFIES each of the eight components as canonical-by-theorem
(with the theorem named) or named-floor (a posited form), reducing (a) to a small,
explicit set of floors rather than an open search.

THE EIGHT COMPONENTS (P18 eq. for O-hat, sec.3):
  O = D2_B4 + Delta_S3 + Delta_S1 + V_self + lambda*rho + gamma*T_cycle + zeta*R + beta*M
  R1 bulk        D2_B4     R5 density   lambda*rho
  R2 boundary    Delta_S3  R6 family    gamma*T_cycle
  R3 fiber       Delta_S1  R7 renorm    zeta*R
  R4 self-lens   V_self    R8 moment    beta*M

WHAT THIS VERIFIER ESTABLISHES (all numpy/sympy, no fitting):
  S0  the three kinetic spectra are the corpus geometric ones                 1-3
  S1  dilation generator R = r d/dr (+Delta_psi) is unique up to add. const    4-5
  S2  T_cycle is the unique Z3 generator selecting L(3,1) (prop:T-canonical)    6-7
  S3  rho and the moments are FIXED corpus objects -> lambda*rho, beta*M
      are multiplication operators, not free operators                          8-9
  S4  the per-category classification: 5 canonical-by-theorem, 2 fixed-mult,
      1 named floor (V_self form) + the already-named APS-BC floor (A329)       10-13
  S5  PARTIAL verdict: (a) reduces to standard invariant-operator uniqueness
      per category + two named floors; T_cycle already closed in P18           14-15

VERDICT: PARTIAL. Sub-result (a) is not an open search: six of the eight components
are forced by named uniqueness theorems (the two Laplacians by Laplace-Beltrami
uniqueness + A328 scale-fixing; the bulk by the Lichnerowicz identity D^2=-Delta+R/4
built in A329, modulo the APS boundary condition = the already-named Heart-2(i)
floor; T_cycle by P18's own orientation argument prop:T-canonical; the renormalisation
generator by dilation-generator uniqueness, shown here), and two more are
multiplication by FIXED corpus objects (the P03 density rho, the P02 moments mu_n),
hence not free. The single genuinely open form is the self-lensing potential V_self
(R4), the named floor A328 corrected to a saturating exponential. So (a) reduces to
exactly two named floors (V_self form; APS BC) plus standard invariant-operator
theory -- an honest reduction, not a closure (the V_self form remains posited).
