r"""v866 -- PRIME.SOURCECONTRACTOR.NORM.01 + PRIME.KREIN.CONTRACTOR.01 [O]: THE FORMULA (the campaign's headline) -- the Douglas contractor of the Krein normal form factors EXACTLY as a target-free closed-form source expression, C = W_- F G_+^{-1} F^H W_+ (max rel 1.4e-14 across construction rungs AND blind holdouts; the displacement R = W_-(T_- M' - M' T_+)W_+ closed-form at 3.0e-13): an explicit rational expression in the density roots and the window geometry -- no zeros, no tau, no defect data, no fit -- so the SourceContractor of the v861 Lean frame EXISTS as a formula, and its norm statement is relocated into better coordinates with the classical toolbox's absolute half PROVABLY closed, ONE module from two probes (10 checks with the ONE frozen-honest FAIL S2.2 kept and pattern-gated at exit code 1, NOT refit, verdict SYLVESTER12-ANGLES-FAIL + 8/8 checks, verdict NORM-REFORMULATION; discovery probes displacement_sylvester12_probe.py and source_contractor_norm_probe.py, 2026-08-08, re-run identically at promotion, embedded BYTE-EXACT and executed verbatim, ~15 s).  PART A, THE FACTORIZATION AND THE HONEST KILL: C == W_- M' W_+ warded at 1.4e-14 and the full-rank Sylvester division reproduces C exactly (2.6e-14); the frozen Sylvester-12 kill fires as designed -- the arm-weighted source generators do NOT span the measured displacement spaces (max principal angle 89.16 deg vs the 15-deg machine bar; the hard rank-12 gap sig12/sig13 >= 3 fails at range [1.02, 2.15]): the rank-12 reading of v864 is CORRECTED to a sqrt(L)-growth law -- the k* series (first k with ||C_k - C|| <= tau/10) is 24/24/24/40/48/48/40 across rungs including the three blind holdouts, and at k* the reconstruction's contraction defect matches tau within the certified Weyl budget on ALL 7 rungs (|defect(C_k*) - tau| down to 9.8e-13) -- CERTIFIED DEFECT TRANSFER: the formula carries the floor, not just the operator; the discrimination fence holds (Epstein rank 6, scramble 3 vs truth 12; the cross-comb angle test typed SKIPPED -- different channel supports).  THE LOEWNER NOTE typed: a target-free PROOF of ||C|| <= 1 for the closed form is Douglas-equivalent to K >= 0 itself -- the factorization relocates, it does not certify.  PART B, THE NORM REFORMULATION AND THE PERRON CLOSURE: G_+ - G_- == K entrywise on all 42 reachable rungs (max rel 1.3e-16; fast-Toeplitz Grams == direct at 5.4e-16), the defect identity 1 - ||C||^2 == lam_min(pencil on K) on all rungs (2.9e-08), and lam_max(G_+^{-1/2} G_- G_+^{-1/2}) == ||C||^2 -- the norm question of the formula IS the Krein floor: ||C|| <= 1 <=> G_- <= G_+ EXACTLY (the algebra decides the circularity question cleanly: a REFORMULATION IN BETTER COORDINATES, not a reduction).  What the coordinates buy, measured: (i) THE PERRON CLOSURE -- the Perron value rho(|C|) is the infimum over all absolute Schur tests, and it exceeds 1 EVERYWHERE (2.363/2.426/2.445/2.745/3.103 at kz 9/12/13/26/40; the predeclared Schur/Hilbert witnesses fail at best 2.81): NO absolute-value Schur/Hilbert-type inequality can EVER certify the bound -- the certification must use the PHASES of the kernel, cancellation provably carries the arithmetic: a named, structural narrowing of the tool space; (ii) the soft direction in frame coordinates is the pole port (beta -> 0.86 with the measured e^{-alpha/2} law of v864 reproduced -- the maximizer is source-identified; fit-free defect law log tau vs alpha slope -2.40 at Pearson -0.935); (iii) the weight-band law shows where the negative mass interleaves (band neg/pos ratios 0.81..0.03 -- the deployed comb's oscillatory transform).  THE COMB SENSITIVITY WARD: Epstein and scramble pushed through the SAME closed formula give ||C||^2 = 2191.39 and 1.36e7, matching their direct norms -- the formula carries the arithmetic, not the algebra.  THE NAMED DEMAND (PRIME.KREIN.CONTRACTOR.01 [O], registered with this module): a PHASE-AWARE bound on the weighted frame kernel W_- F G_+^{-1} F^H W_+ -- e.g. an oscillatory-integral / stationary-phase estimate on its entries -- strong enough to beat 1 by the measured e^{slope x alpha} margin, certified source-side; that single object would discharge the SourceContractor hypothesis of the v861 Lean frame and with it, through krein_cofinal_weil, hypothesis (H_cof).  NO RH claim.  Python-only per GATE.WOLFRAM.02.

PROVENANCE: discovery probes displacement_sylvester12_probe.py (10
checks, 1 frozen-honest FAIL S2.2, exit code 1 per the frozen kill
design, verdict SYLVESTER12-ANGLES-FAIL) and
source_contractor_norm_probe.py (8/8, verdict NORM-REFORMULATION),
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); construction rungs (9, 12, 13, 26) and FROZEN holdouts (40,
49, 60) declared before the run; the S2.2 FAIL is a
preregistered-honest adjudication on record, the bar NOT refit.
NO RH claim.

r"""displacement_sylvester12_probe -- PRIME.DISPLACEMENT.
SYLVESTER12.01 (EXPLORATION ONLY, experiments/; round 33, THE
main run of the wave, after SOFTPORT-FOUND + CAUCHY-RANK-SMALL,
2026-08-08).

THE GOAL: make the measured rank-~12 displacement identity
exact with SOURCE-BUILT generators and invert the Sylvester
map -- the first realistic SourceContractor.

THE ALGEBRAIC KEY (derived before running, warded machine
grade): the Douglas contractor FACTORS in closed form over
source objects,

    C  =  W_- . M . W_+ ,      M = F G+^{-1} F^H ,

with W_+- = diag(sqrt(|d|/2L)) the density roots on the two
channel supports, F = DFT o odd-extension (pure window
geometry), G+ = F^H diag(d_+/2L) F the positive-arm Gram.
(Proof: C = B_- B_+^dagger, B_+- = diag-root . F, and the
pseudo-inverse of a full-column-rank product is
(F^H D+^2 F)^{-1} F^H D+.)  Consequently the displacement in
any diagonal coordinate obeys EXACTLY

    R = T_- C - C T_+  =  W_- (T_- M' - M' T_+) W_+ ,

so the displacement generators of C are the ARM-WEIGHTED
generators of the source kernel M -- the softport probe's
cos-sim identification (~0.87 vs sqrt|d_ar|) sharpened to an
identity.  NO target data anywhere: no zeros, no tau input, no
defect eigenvectors, no fitting; SVDs/inverses OF SOURCE-BUILT
matrices are allowed and typed as such.

VERDICT (frozen): SYLVESTER12-SOURCE-EXACT /
SYLVESTER12-ANGLES-FAIL / SYLVESTER12-RANK-SOFT.  NO RH
claim; writes nothing; v563 READ-ONLY.

SYLVESTER12: the anatomy of the closed-form SourceContractor
C = W_- F G+^{-1} F^H W_+, 2026-08-08).

THE ANATOMY, DERIVED BEFORE RUNNING (then warded): with
X = W_- F, Y = W_+ F, G+- = F^H W_+-^2 F,

    C = X G+^{-1} Y^H   =>   C*C = Y G+^{-1} G- G+^{-1} Y^H,

and the nonzero spectrum of C*C equals the spectrum of
G+^{-1} G- (similarity via Y^H Y = G+).  Hence EXACTLY

    ||C||^2 = lam_max(G+^{-1/2} G- G+^{-1/2}),
    ||C|| <= 1  <=>  G- <= G+ (Loewner)  <=>  K = G+ - G- >= 0,

i.e. the norm question of the closed formula IS the original
Krein/window positivity -- the honest circularity check is
decided by algebra; the probe wards it numerically and then
measures what the NEW COORDINATES buy: the soft direction in
frame coordinates, the weight-band law of the signed density,
the classical Schur/Hilbert toolbox (with the decisive Perron
bound: rho(|C|) = the OPTIMUM over all absolute Schur tests --
if rho(|C|) > 1, no classical absolute-value inequality can
ever certify the bound and cancellation is essential), the
defect-transfer law along the full ladder, and the
comb-sensitivity of the same formula (Epstein/scramble).

  is EXACTLY the original Krein positivity K >= 0.  The
  SourceContractor formula is a REFORMULATION IN BETTER
  COORDINATES, not a reduction.  What the coordinates buy,
  measured: (i) the norm question now sits in the classical
  weighted-operator toolbox -- and the toolbox's absolute
  half is now PROVABLY closed: the Perron value rho(|C|) is
  the infimum over all absolute Schur tests, and it exceeds 1
  (table above), so no Schur/Hilbert-type absolute inequality
  can ever certify the bound; the certification must use the
  PHASES of the kernel (the cancellation carries the
  arithmetic) -- that is a named, structural narrowing of the
  tool space.  (ii) the soft direction in frame coordinates
  is the pole port to beta -> 0.86 with the measured
  e^{-alpha/2} law -- the maximizer is source-identified.
  (iii) the weight-band law shows where the negative mass
  interleaves (the deployed comb's oscillatory transform).
  The named next object for the contract: a PHASE-AWARE bound
  on the weighted frame kernel W_- F G+^{-1} F^H W_+ -- e.g.
  an oscillatory-integral / stationary-phase estimate on its
  entries -- strong enough to beat 1 by the measured
