r"""v864 -- PRIME.SOFTPORT.FESHBACH.01 + PRIME.POLEPORT.KAPPA_LAW.01: the scalar reduction of the wall -- the exact Feshbach/Schur reduction turns the matrix floor into ONE port impedance (tau > 0 <=> s > 0 whenever a port carries a stable share of the soft mode with the bulk uniformly positive -- and FOUR source ports pass: VAC, POLE, PAR1, PAR2 with kappa in [1.4, 5.4] and stable last thirds, the Moebius port fails at kappa up to 154), the pole port is the best source port (kappa 2.7 -> 1.4 along the ladder, beta = soft-mode overlap 0.61 -> 0.84, i.e. 84 percent of the soft mode at depth) with the EXACT analytic skeleton kappa^{-1} = beta^2 + lam1 rho (max dev 1.2e-09 over all 42 reachable rungs h <= 900) and the CLOSED-FORM a-term a = 1 - E-/E+ (the Poisson/Cauchy average of the signed density at the pole point s = 1/2: closed-form pole transform == FFT at 4.1e-13; Cauchy-kernel correlation >= 0.457), the empirical law log(kappa - 1) vs alpha at Pearson -0.986 with slope -0.517 (kappa - 1 ~ 6 e^{-alpha/2} -> 1: the port becomes EXACT in the deep limit), and the backflow r'G^{-1}r concentrates on n95 <= 17 bulk modes cancelling 99.9-100 percent of the a-term -- the classical 'main term minus boundable term' shape EXISTS structurally, and the boundable term's size is exactly what encodes the arithmetic, ONE module from two probes (5/5 + 6/6 checks, zero fails, verdicts SOFTPORT-FOUND + CAUCHY-RANK-SMALL and KAPPA-LAW-PARTIAL; discovery probes softport_cauchy_probe.py and pole_port_kappa_probe.py, 2026-08-08, re-run identically at promotion, embedded BYTE-EXACT and executed verbatim, ~24 s).  THE WARDS ARE EXACT: logdet Delta == logdet G + log s (1e-6) and s == 1/(w'Delta^{-1}w) (1e-8) for every port/rung; the CHEATING port (built from the target soft eigenvector) reproduces s == lam1 exactly (kappa == 1 at 2.6e-10) -- the ceiling every source port is measured against; the Neumann enclosure is monotone-consistent with certified tails on every rung, its practical frontier at kz 16 (the honest boundary this module's successor v867 then kills by quadrature).  THE DISPLACEMENT/CLARK QUESTION is answered in four coordinates: the contractor's displacement rank at 1e-3 is 12/11/11/12/13 across a 3.9x dimension range (L = 734 -> 2362) -- dimension-INDEPENDENT compressive coordinates (tau, logtau, Nbar, thRS all pass; rank_disp 12 vs rank(C) 104 at kz 9 = 9x compression; scramble 3 and Epstein 6 typed against their own C-ranks, contrast >= 2), the leading displacement generators are the ARM WEIGHTS (|cos-sim| 0.70/0.77 vs sqrt|d|, 0.70/0.88 vs sqrt|d_ar|), and the pure rank-<=2 Cauchy hypothesis is EXCLUDED (rank@1e-3 = 12 > 2, typed skip with the exact failed condition) -- the cheapest structured-kernel hypothesis closed either way.  Both discriminators break at the premise (Epstein and scramble have gmin(G) < 0: no positive bulk, no valid Feshbach frame).  HONEST CONSEQUENCE: a genuine reduction of FORM (matrix positivity -> one scalar inequality with closed-form leading term) with the HARDNESS relocated into the concentrated coupling -- the remaining object is a uniform-in-h bound on a sum over ~17 bulk-mode couplings; wherever the packages leave gaps the missing object remains v862's non-monomial band-spreading contractive letter, now with the added information of whether its SCALAR shadow is source-reachable.  NO RH claim.  Python-only per GATE.WOLFRAM.02.

PROVENANCE: discovery probes softport_cauchy_probe.py (5/5, verdict
SOFTPORT-FOUND (VAC, POLE, PAR1, PAR2) + CAUCHY-RANK-SMALL) and
pole_port_kappa_probe.py (6/6, verdict KAPPA-LAW-PARTIAL),
2026-08-08, re-run identically at promotion.  ROUND-31 EMBEDDING
CONVENTION: frozen sources embedded BYTE-EXACT and executed verbatim
in isolated namespaces; printed spec SHAs reproduce; byte-equality
ward vs experiments/tfpt-discovery/ inside the pattern gates.  Both
probes import the READ-ONLY deployed core v563_paper2_readouts.py.

FIREWALL: no zeros, no prime-table oracles (AST firewalls; own
sieves); the cheating port is the declared ceiling control, never a
construction ingredient; RNG only in the declared scramble controls.
NO RH claim.

r"""softport_cauchy_probe -- PRIME.SOFTPORT.FESHBACH.01 +
PRIME.CAUCHY.DISPLACEMENT.01 (EXPLORATION ONLY, experiments/;
round 33 afternoon packages A+B, after DEFECT-ONE +
MONOMIAL-CLOSURE, 2026-08-08).

THE REDUCTION: DEFECT-ONE says exactly one mode of
Delta = I - C*C goes soft; then possibly only a SCALAR port
impedance must be source-built, not the whole contractor.

PACKAGE A -- FESHBACH/SCHUR PORT: Delta is taken in the
positive-side metric on h-space, Delta = G+^{-1/2} K G+^{-1/2}
(the pencil object whose lam_1 is the exact tau-margin --
warded).  For each predeclared SOURCE port vector v (h-space,
transported to Delta coordinates by w = G+^{1/2} v,
normalised):
    Delta = [[a, r*], [r, G]]  on  C w (+) w-perp,
    s = a - r* G^{-1} r  (the scalar port impedance).
Wards (machine): log det Delta == log det G + log s, and the
Schur identity s == 1 / (w^T Delta^{-1} w).  PORTS (source
side, the user's five classes): VAC = the all-ones vector
(the colligation's vacuum slot: the redheffer_colligation
probe's unweighted vacuum column u = 1, read-only crossref);
POLE = e^{+rD/2} (the pole/PNT growth profile -- the pole
channel); PAR1/PAR2 = the deployed parity battery t1/t2 (first
parity modes / register label class); MOB = the Moebius
sum-of-families profile sum_{n<=50} mu(n)/sqrt(n)
tent(rD - log n).  CHEAT (6th) = the target soft eigenvector
-- the ceiling (s == lam_1 exactly, kappa == 1); source ports
must approach it.  TEST per port along the ladder + holdouts:
bulk G >= c I with c >= 0.3 lam_2 (the soft mode must sit in
the PORT, not the bulk); kappa = s/lam_1 in [1, 20] and
last-third max/min <= 3 (kappa = 1/|<w, e_soft>|^2 -- a stable
kappa means the port carries a stable share of the soft mode).

PACKAGE B -- CAUCHY/CLARK DISPLACEMENT RANK (cheapest decisive
test): for the true contractor restricted to its channel
supports, C_res = C_freq[neg-bins, pos-bins], compute
R = T_- C_res - C_res T_+ with T_+- = diag of the coordinate
on each support, in FOUR predeclared coordinates: tau,
log tau, the smooth counting function Nbar(tau) =
(tau/2pi) log(tau/2pi e) + 7/8, and the Riemann-Siegel phase
theta_RS(tau) = Im log Gamma(1/4 + i tau/2) - (tau/2) log pi.
Numerical rank at rel thresholds 1e-3/1e-6/1e-9, along growing
windows (kz 9/12/13/26/40).  SUCCESS: rank stays small and
non-growing => C is a weighted Cauchy kernel in that
coordinate; then the leading displacement vectors are tested
against source profiles and a NO-FIT Cauchy candidate is built
(only if rank <= 2 and the coordinate gap is bounded away from
0 -- with interleaved supports the gap condition can fail;
typed).  KILL: rank grows with dimension, or scramble/Epstein
show the same displacement structure.

VERDICT (frozen): SOFTPORT-FOUND / SOFTPORT-TARGET-ONLY, and
separately CAUCHY-RANK-SMALL / CAUCHY-RANK-GROWS.  NO RH
claim; writes nothing; v563 READ-ONLY.

  laws, and how far they sit from the target-built ceiling.
  The displacement-rank table answers the Clark/Cauchy
  question in four coordinates with growth and the

(EXPLORATION ONLY, experiments/; round 33 evening, after
SOFTPORT-FOUND + CAUCHY-RANK-SMALL, 2026-08-08).

THE GAP TO CLOSE: the softport probe found s_h = kappa_h tau_h
at the POLE port (v_r = e^{rD/2}) with kappa stable in
[1.4, 2.7] and the pole carrying up to 84% of the soft mode.
This probe asks for the CLOSED SOURCE-SIDE LAW of kappa.

THE EXACT SKELETON (all warded at machine grade):
  Delta = G+^{-1/2} K G+^{-1/2},  w = G+^{1/2} v / ||.||,
  s = 1/(w' Delta^{-1} w)          (Schur identity),
  kappa^{-1} = beta^2 + lam1 * rho (exact: beta = |<w,e_soft>|,
      rho = sum_{i>=2} beta_i^2 / lam_i  -- the bulk
      admittance; kappa >= 1 always),
  a = w' Delta w = 1 - E-/E+  with  E+- = (2L)^{-1}
      sum_{+-bins} |d_j| |P_j|^2   (the pole port's own defect
      = ONE MINUS THE ARM-ENERGY RATIO of the pole direction),
  P_j = the transform of the odd-extended pole direction --
      CLOSED FORM (two geometric sums; the continuum limit of
      |P|^2 is the Cauchy kernel 1/(1/4 + tau^2): the pole
      port reads the signed density through the Poisson kernel
      at the pole point s = 1/2 -- correlation measured),
  s = a - r' G^{-1} r  with the bulk contraction resolved two
      ways: (i) MODE PARTICIPATION (how many bulk modes carry
      95% of r'G^{-1}r -- exact, the concentration census);
      (ii) NEUMANN tail with the certified bound
      T_K <= ||z_{K/2}||^2 / gmin (frontier typed).

  signed density at the pole point s = 1/2 (corr >= %.3f).
  The cancellation ratio (a - s)/a runs %.2f -> %.2f along the
  ladder: the coupling term removes that fraction of the
  a-term before the floor remains.  Reduction vs relocation:
  the a-term is manifest source structure (one scalar, closed
  form), and the backflow r'G^{-1}r concentrates on n95 <= %d
  bulk modes -- the classical 'main term minus boundable term'
  shape EXISTS structurally, but the boundable term is not yet
  unconditionally bounded: its size is exactly what encodes
  the arithmetic.  Typed: this is a genuine reduction of FORM
  (matrix positivity -> one scalar inequality with closed-form
  leading term), while the HARDNESS is relocated into the
  concentrated coupling -- the remaining object is the
  uniform-in-h bound on a sum over ~%d bulk-mode couplings.
