r"""v868 -- E8.DIVISOR210.CANONICITY.01 (+ the moving-12 and chirality audits): the hard canonicity guard for the 210 discovery of v863 -- the Boolean/Walsh/mu layer is MEASURED GENERIC exactly as warned (210/210 quadruples of primes < 30 pass it: layer one carries NO selection content), the deployed scalar-limit Euler constants pin {2,3,5,7} UNIQUELY (Q1: prod(1-1/p) == 8/35 exact in Fractions has 1 match; Q2: prod(1-p^{-1/2}) == the deployed value with exact radical maps has 1 match, non-matches separated by >= 5.2e-3 at 50 digits; the tautological prod p == 210 test excluded from the verdict), the anchor prime 2 is FORCED by the frozen ramification crossref R3 (2 = the unique Z[i]-ramified prime onto the unique sigma-fixed q*=1 class -- the very prime at which V = L/(1+i)L is cut), the mu4 weld grade cuts the gauge C6 -> C3 (|G3| = 3 measured) and the axis freedom 2 -> 1 sets, and after R3 exactly TWO gauge classes remain -- the family-cycle CHIRALITY ((3,5,7) vs (3,7,5)), which the chirality audit then PROVES gauge at the deployed-machine level, ONE module from three probes (36/36 + 12/12 + 15/15 checks, zero fails, verdicts DIVISOR210-GAUGE-FAMILY(2), MOVING12-DIMENSION-ONLY, CHIRALITY-DEGENERATE; discovery probes divisor210_canonicity_probe.py, moving12_soft17_probe.py and chiral_phase_probe.py, 2026-08-08, re-run identically at promotion, embedded BYTE-EXACT and executed verbatim, ~6 s).  PART A, CANONICITY: the full 65536-matrix census gives |Sp(4,2)| = 720 with the Gram-only baseline a simply transitive torsor (720 ordered bases) -- the deployed pins cut 720 -> 6 ordered bases (factor 120): the SEMANTICS, not the lattice shape, carry the selection; the role census over all admissible bases x 24 bijections (48 identifications, 24 weld-compatible) types every layer: the Boolean battery forces NOTHING (48/48), the register forces the anchor BIT (unique sigma-fixed q*=1 class), R3 forces the anchor PRIME = 2 (12/48 survivors), the weighted-sigma criterion is typed NOT-a-filter (three distinct primes can never have equal half-weights; the deployed design applies weights as modular phases), the Z[i]-splitting profile of the family primes (5 splits, 3 and 7 inert) admits NO C3-symmetric 3-cycle -- the family symmetry is REGISTER-SIDE ONLY; both scramble controls fire (sigma'=id, q'=0: NOTHING passes, the gauge explodes to 720; flavor 2: anchor census 10 != 1 -- the family 3-cycle is load-bearing); the 6-vs-7 HONESTY NOTE stands untouched: the clock alphabet {2,3,5,6} and the prime quadruple {2,3,5,7} are DIFFERENT objects (6 = 2*3 = |R+(A3)| sits inside the divisor lattice as the unique weight-2 divisor from two alphabet primes; 7 = 6+1 is prime and not in the alphabet) -- not smoothed over.  PART B, THE MOVING-12 BURIAL (honest): the register split 3 + 12 and the isotypic structure are EXACT (C^15 = triv^7 + om^4 + ombar^4; moved sector = 4 x regular; the divisor census 17 = 12 + 3 + 1 + 1 with both gauge classes giving EQUAL moved sets) and the measured objects reproduce (displacement rank 12 non-growing, n95 = 16, top-17 bulk modes carry 0.957 of the backflow) -- but the space-level identification through the only deployed bridge (the divisor modular frame, conditioning smin/smax = 0.84) gives max principal angles 1.5703/1.5617 rad against the frozen 1e-6 bar (90 deg = 1.5708: ORTHOGONAL; the foreign-frame contrast 0.0004 says the frame does not see the displacement structure at all), nontrivial character share 0.755, effective multiplicities (9.7, 3.1, 0.9, 3.3) != (12, 3, 1, 1): the 17 = 12+3+1+1 arithmetic stands as a COUNT, the identification hypothesis is BURIED at space level unless a different intertwiner is exhibited -- typed, not smoothed.  PART C, CHIRALITY IS PROVEN GAUGE (two exact no-go wards): (1) the register orientation functional vanishes IDENTICALLY -- the Moebius complement d -> 210/d pairs the 4 free orbits with reversed orientation (X1(O)^3 + X1(O')^3 = 0 per pair at 4.1e-15) for EVERY multiplicative weight assignment: the register's multiplicative weight structure carries NO intrinsic scalar orientation, the KMS-orientation criterion is VACUOUS; (2) every sigma-less phase readout is PROVABLY chirality-blind (U0_- == Pi U0_+ Pi^T exact, loaded scalars identical at 5.6e-17) and the sigma-wired machine's QUADRATIC readout is chirality-equal to machine precision (1.8e-15: the symmetric form w2'Vt w2 cannot see the cycle orientation -- transposition kills it; even the asymmetric diagnostic w2'Vt w1 reads |dPhi| = 0.0, report-only) -- the residual Z2 is REAL GAUGE at the deployed-machine level, the canonicity verdict stands and is NOT upgraded; the scrambled-register control fires (multiplicativity violated on 21 pairs, machine readout moves at 8.2e-2).  All three parts are audits of a DEPLOYED discovery (the v863 scalar-limit determinant) -- selection census, burial, and no-go wards; no new physical claim, no marker moves.  NO RH claim.  Python-only per GATE.WOLFRAM.02.

PROVENANCE: discovery probes divisor210_canonicity_probe.py (36/36,
verdict DIVISOR210-GAUGE-FAMILY(2)), moving12_soft17_probe.py
(12/12, verdict MOVING12-DIMENSION-ONLY) and chiral_phase_probe.py
(15/15, verdict CHIRALITY-DEGENERATE, spec v2 with the two
structural no-go wards), 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.  The moving-12
probe imports pole_port_kappa_probe.py (gated in v864) and
softport_cauchy_probe.py (gated in v864) READ-ONLY; the chirality
probe imports krein_normalform_probe.py (v861),
redheffer_colligation_probe.py (v863), divisor_weyl_port_probe.py
and weyl_readout_repair_probe.py (v865) READ-ONLY -- none re-gated
here.

FIREWALL: no zeros, no prime-table oracles beyond sympy factorint on
the 16 register labels (AST firewalls inside the probes); the
blind-protocol decider rules of the chirality probe frozen before
evaluation; scramble controls MUST-FIRE and do.  NO RH claim.

the hard canonicity guard for the 210 discovery.

EXPLORATION ONLY (experiments/): no ledger row, no paper edit, no .md,
nothing outside experiments/.  NO RH claim.  Frozen (spec + sha256)
before running.  Exact integer/Fraction arithmetic; sympy only for one
rational determinant, factorint cross-checks and the 50-digit

THE FINDING TO GUARD (redheffer_colligation_probe, read-only): the
16-label Gaussian register F_2^4 was identified with the divisor
lattice of 210 = 2*3*5*7 (bits = primes), with Walsh-Hadamard carrying
the lattice Moebius mu as signs, and the two scalar-limit Euler
constants det_A = prod_p (1 - 1/p) = 8/35 (both-half-weighted vacuum
closure) and det_B = prod_p (1 - p^{-1/2}) (unweighted vacuum column).

THE GENERICITY DANGER (predeclared): EVERY squarefree N = p1 p2 p3 p4
gives a Boolean 16-lattice ~ F_2^4 with mu(d) = (-1)^omega(d) a Walsh
character -- the first layer is generic and the census MUST measure it
as generic.  The specific content, if any, must come from (a) the
SEMANTICALLY FIXED four bits of the deployed register (family 3-cycle
sigma, anchor bit A, mu4 weld grade, code gradings q*/iota) and (b)
the deployed scalar-limit constants.

FROZEN PROTOCOL (2026-08-08, frozen + SHA-hashed before first run):

 S1  REGISTER REGRESSIONS (control 1; v845 NORMALFORM.CFIN.01
     machinery rebuilt read-only): Construction-A Gaussian E8 (C*, 2
     of 30 placements); census 240 = 15 x 16, zero class EMPTY; sigma
     descends with exactly 3 fixed nonzero classes; family/anchor
     basis (F1,F2,F3,A) found with Gram(hbar) = J - I and hbar == the
     bit form on all 256 pairs; sigma in bits = (f1,f2,f3,a) ->
     (f3,f1,f2,a); EXACTLY 16 quadratic refinements, Arf census
     6 + 10, selector (sigma-invariant 4 -> q(A)=1 2 -> q(F_Sigma)=0
     1) picks the unique q* of Arf type 1; iota bijective onto
     C_even(5), beta == hbar, q_wt == q*, 3+2 slot action.  Any fail
     => REGISTER-BROKEN.

 S2  THE DEPLOYED GAUGE (computed exactly, bit model):
     (a) |Sp(4,2)| = 720 by full 65536-matrix census;
     (b) G1 = {g in Sp : g sigma = sigma g, q* o g = q*};
     (c) G2 = Aut(C_fin) = {g in G1 : exists pi in S5 with
         iota o g = pi o iota} -- REGRESSION: |G2| = 6, cyclic
         (CFIN.UNIQUE.01, Aut(C_fin) ~ C6); fail => GAUGE-BROKEN;
     (d) G3 = {g in G2 : wt(g v) = wt(v) for all v} -- the subgroup
         preserving the mu4 weld grade i^{wt} (deployed coordinates);
         MEASURED (expected C3 = <sigma>; the weld grade is extra
         structure beyond C_fin -- typed either way);
     (e) THE ANCHOR FORCING, register side: the number of sigma-fixed
         nonzero classes with q* = 1 (bar: exactly 1 = A);
     (f) THE AXIS FREEDOM: census of all ordered admissible bases
         (X1,X2,X3,A') -- pins: A' sigma-fixed nonzero with q*=1;
         sigma X1 = X2, sigma X2 = X3 (free 3-orbit); {X1,X2,X3,A'}
         independent with A' outside span(X1,X2,X3); Gram(hbar) =
         J - I; q*(X1+X2+X3) = 0.  Count ordered bases, unordered
         axis sets, G2-transitivity, and the weld-compatible subset
         (Hamming weight in basis coordinates == deployed weight for
         all 16 classes).  All counts MEASURED.

 S3  THE FINDING REBUILT (control 2, deployed quadruple {2,3,5,7}):
     Walsh signs 4*WH[1111, v] == mu(d(v)) = (-1)^{wt v} on all 16
     labels (exact Fractions, mu cross-checked against factorint);
     the lattice zeta matrix Z has inverse M[S,T] = [S<=T]
     (-1)^{|T \ S|} (exact integer product Z M == I); det variant A:
     det(Z + u e_1^T) with u[b] = 1/b (b > 1) == 8/35 by direct
     16 x 16 rational determinant AND by the matrix-determinant lemma
     1 + sum_{b>1} mu(b)/b; det variant B: 1 + sum_{b>1} mu(b)
     b^{-1/2} == prod_p (1 - p^{-1/2}) by EXACT radical-expansion
     maps {squarefree radicand: coefficient} (linear independence of
     distinct squarefree radicals over Q, Besicovitch, cited not
     re-proved); two foreign witnesses ({3,5,7,11}, {2,3,5,11}) give
     different det_A values (exact).  Any fail => FINDING-BROKEN.

 S4  THE QUADRUPLE CENSUS (predeclared field: ALL C(10,4) = 210
     quadruples of distinct primes < 30, i.e. 4-subsets of
     {2,3,5,7,11,13,17,19,23,29}; the count 210 = 2*3*5*7 is a
     pleasing COINCIDENCE, typed as such, not evidence):
     (B)  Boolean layer: mu(d) == (-1)^{omega(d)} == the full-parity
          Walsh character for every quadruple -- the genericity
          measurement (predeclared expectation: 210/210 pass; this
          layer carries NO selection content);
     (Q1) Euler test: prod_p (1 - 1/p) == 8/35, exact Fraction --
          count matches;
     (Q2) half-weight test: prod_p (1 - p^{-1/2}) == the deployed
          value, compared as EXACT radical-expansion maps -- count
          matches; plus the 50-digit separation diagnostic (minimum
          |difference| over non-matching quadruples, bar 1e-40);
     (T)  prod_p == 210: tautological (the modulus was DEFINED from
          the primes) -- typed, excluded from the verdict.

 S5  THE ROLE CENSUS (for the Q1-and-Q2-surviving quadruple(s)):
     IDENTIFICATIONS = { linear isos phi : V -> divisor group, phi =
     (ordered admissible basis from S2f) x (bijection axes ->
     primes) }, deduplicated as label maps (cyclic re-rooting of a
     basis gives the same phi).  Register gauge acts by phi -> phi o
     g; PRIMARY gauge = G3 on the weld-compatible identifications
     (the finding-to-guard uses the weld grade in design (b));
     SECONDARY reading = G2 on all identifications (measured; the
     final class count must agree or the discrepancy is typed).
     Frozen battery per identification:
     (i)   grading: wt_deployed(v) == omega(phi(v)) for all 16 AND
           mu(phi(v)) == (-1)^{wt v} -- measured (pin for the weld-
           compatible set, fails for weld-incompatible bases: typed);
     (ii)  sigma transport: phi o sigma o phi^{-1} == the
           multiplicative extension of the 3-cycle (p_{X1} p_{X2}
           p_{X3}) fixing p_{A} on all 16 divisors -- measured
           (predeclared expectation: passes for ALL bijections; the
           Boolean lattice is S4-symmetric, so (ii) alone forces NO
           anchor prime -- the honest genericity of layer two);
     (iiw) weighted sigma: the transported 3-cycle preserves the
           half-weights w(d) = d^{-1/2} iff the three family primes
           are EQUAL -- measured (expected 0 pass); TYPED, NOT a
           filter: the deployed design (b) applies the weights as
           modular phases on which sigma acts covariantly, not
           invariantly;
     (iii) R3, THE ONLY FROZEN ROLE FILTER: phi(A) == 2.  Rationale
           (frozen): the register V = L/(1+i)L is the quotient at the
           RAMIFIED prime of Z[i] ((1+i)^2 = 2i, N(1+i) = 2); 2 is
           the unique ramified prime, the anchor A is the unique
           sigma-fixed q*=1 class -- uniqueness matched to
           uniqueness.  Quadruples without 2 admit no R3 assignment
           (84 = C(9,3) of 210 contain 2 -- context, measured);
     (iv)  Z[i]-splitting profile (measured, typed, NOT a filter):
           for R3 survivors the family primes are {3,5,7} =
           (inert, split, inert) (p mod 4 = 3,1,3); no prime 3-cycle
           preserves the splitting type -- the family symmetry is
           register-side only; honesty note #2;
     (v)   compiler crossrefs (measured, typed, NOT filters):
           {2,3,5} == {|Z_2|, N_fam, g_car} exact; the clock alphabet
           {2,3,5,6} vs the quadruple {2,3,5,7}: overlap {2,3,5},
           MISMATCH 6 != 7 typed, not smoothed (6 = |R+(A3)| = 2*3 is
           itself the unique weight-2 divisor of 210 built from two
           alphabet primes; candidate exact readings of 7 measured:
           7 == |R+(A3)| + 1 == 2^{N_fam} - 1 == 15 - 8 = the
           adjoint-side class count of the v845 S7 census; NO
           selection among them); the pointwise reading family bits
           -> {2,3,5} = {|Z_2|, N_fam, g_car} is GAUGE-INCONSISTENT
           (the family bits are gauge-symmetric, the three constants
           are semantically distinct) -- typed.

 S6  VERDICT (frozen precedence):
     REGISTER-BROKEN / GAUGE-BROKEN / FINDING-BROKEN as above;
     else let nQ = #quadruples passing Q1 AND Q2:
       nQ != 1                       -> DIVISOR210-GENERIC (typed,
                                        with the Euler results);
       nQ == 1: let k = #primary-gauge classes of identifications
       passing the frozen filter R3:
         k == 1                      -> DIVISOR210-CANONICAL;
         2 <= k <= 8                 -> DIVISOR210-GAUGE-FAMILY(k)
                                        (the residual freedom typed
                                        from the measured orbits);
         k == 0 or k > 8             -> DIVISOR210-GENERIC.
     CONTROL-DEAD if any control fails to fire.

 S7  CONTROLS (must fire):
     C1 register regressions = S1 (above);
     C2 Walsh-mu sign identity + both det closed forms = S3 (above);
     C3 SCRAMBLED REGISTER (anti-vacuity ward): drop the structure
        (sigma' = id, q' = 0): the anchor census 1 -> 0, the
        admissible-basis census 6 -> 0 (NOTHING passes -- the census
        discriminates), the gauge explodes to full Sp(4,2) = 720;
        flavor 2 (sigma' = id, q' = q*): anchor census -> 10 (not
        unique); Gram-only baseline: ordered bases with Gram J - I
        alone = 720 (simply transitive Sp-torsor) vs 6 with the
        deployed pins -- the semantics cut 720 -> 6.  Fire rule: all
        three measured collapses occur.

DELIVERABLES: the gauge-group computation, the census table
(aggregates + all matching rows), the 6-vs-7 honesty note, the
verdict with what forces what, controls, honest consequence.

WHAT FORCES WHAT (measured):

   (prod(1-p^{-1/2}), exact radical maps) has %d match(es) in the
   predeclared 210-quadruple field.  The Boolean/Walsh/mu layer is
   MEASURED GENERIC (210/210), exactly as warned: every squarefree
   quadruple gives that layer for free.
 * ROLE level: the Boolean battery ((i),(ii)) passes for every
   bijection -- it forces NOTHING.  The register forces the anchor
   BIT (unique sigma-fixed q*=1 class, measured 1); the frozen
   ramification crossref R3 (2 = the unique ramified prime of Z[i],
   the very prime at which V = L/(1+i)L is cut) forces the anchor
   PRIME = 2.  After R3, %d gauge class(es) remain: the residual
   freedom is the family-cycle CHIRALITY (which cyclic order of
   {3,5,7} sits on F1 -> F2 -> F3); no register structure orders the
   cycle beyond cyclically, and no {3,5,7} arithmetic structure is
   C3-symmetric (splitting profile inert/split/inert, measured).
 * The mu4 weld grade is EXTRA structure beyond C_fin: it cuts the
   gauge C6 -> C3 (|G3| = %d) and the axis freedom %d -> %d sets;
   both gauge readings give the same final class count.

HONEST CONSEQUENCE: the 210 identification is NOT generic at the
constants level (the Euler dets select {2,3,5,7} uniquely in the
predeclared field) and NOT canonical at the role level without the
ramification crossref; with R3 frozen it is canonical up to the
family-cycle chirality.  The 6-vs-7 mismatch with the clock alphabet
{2,3,5,6} stands and is typed, not resolved.  Exploration only; no
ledger/paper/website claim; NO RH claim.

r"""moving12_soft17_probe -- E8.MOVING12.SOFT17.01: the hypothesis
17 = 12 + 3 + 1 + 1, audited at SPACE level (projectors, principal
angles, characters), not by number-matching.

EXPLORATION ONLY (experiments/): no ledger row, no paper edit, no
.md, nothing outside experiments/.  NO RH claim.  Frozen (spec +
sha256) before running.

BACKGROUND (read-only): the family 3-cycle sigma splits the 15
nonzero register labels as 3 fixed classes + 4 free 3-orbits =
3 + 12 (exact, v845/finite_compiler); the softport analysis
measured a dimension-independent displacement structure of rank
~12 in the tau coordinate (softport_cauchy_probe, run-1 ranks
12/11/11/12/13 over a 3.9x dimension range) and the pole-port
backflow concentrates on n95 <= 17 coupled bulk modes
(pole_port_kappa_probe).  THE HYPOTHESIS: 12 displacement
generators = the 12 sigma-moved label channels; 3 fixed classes =
the static bulk; + 1 vacuum slot; + 1 pole port.

THE GENERICITY DANGER (pre-typed): 12 = 12 and 17 = 12 + 3 + 1 + 1
as NUMBERS is numerology; the audit must compare SPACES.  The
frozen bridge (the only deployed register -> grid map available):
the DIVISOR MODULAR FRAME -- label S with divisor d(S) (the
divisor-210 register, canonicity probe read-only; the moved/fixed
divisor SETS are chirality-independent, verified) maps to the bin
profile phi_d(j) = d^{-i tau_j / 2} (the KMS/modular frequency of
the deployed half-weight d^{-1/2}, redheffer design (b) phases);
the 17-frame = {vacuum d=1} + {3 fixed divisors 2, 105, 210} +
{12 moved divisors} + {pole profile P_j, closed form}.  If the
angles do NOT close, the honest verdict is the burial, typed.

FROZEN PROTOCOL (2026-08-08, frozen + SHA-hashed before first run):

 S1  REGISTER SIDE (exact, bit model; v845 conventions, the
     Construction-A regressions live in the canonicity probe
     read-only): sigma (f1,f2,f3,a) -> (f3,f1,f2,a); fixed nonzero
     = {A, F_Sigma, F_Sigma + A} (3), moved = 12 in exactly 4 free
     3-orbits; the label projectors on C^15: P_moved (12-dim),
     P_fixed (3-dim), exact; the C3 isotypic dimensions EXACT:
     C^15 = triv^7 + om^4 + ombar^4, moved sector = 4 x regular =
     (4, 4, 4), fixed sector = triv^3; the census divisor maps
     (both gauge classes (3,5,7,2) / (3,7,5,2)) give the SAME
     moved/fixed divisor sets; the identity 17 = 12 + 3 + 1 + 1.

 S2  MEASURED OBJECTS (pole_port/softport machinery imported
     read-only; rungs 9/12/13, displacement-rank series also at
     26/40): REGRESSIONS: lam1(Delta) at anchors == softport refs
     {1.675e-4, 7.647e-5, 7.824e-5} rel 1e-3; kappa_POLE(kz9) in
     [2.6, 2.8]; n95 <= 20 with the kz-9 value reported (the
     measured concentration behind the '17'); displacement
     rank@1e-3 in tau at kz9 in [11, 13] and non-growing over
     {9,12,13,26,40} (max <= min + 3).  Objects kept: U = leading
     left displacement vectors (neg bins), V = right (pos bins),
     the top-17 coupled bulk modes (coupling census ci from the
     exact Feshbach split), each transported to bin space by the
     deployed transform (Delta-coords -> h by G+^{-1/2}, then the
     plain odd-extension transform Fp; frozen choice, typed).

 S3  THE FRAME: the 17 bin profiles as above, each normalized;
     conditioning census (singular values of the 17-frame; the
     frame must be numerically independent, smin >= 1e-3).

 S4  PRINCIPAL ANGLES (the space test; angles via SVD of Qa* Qb):
     (b1) span(U) vs moved-frame restricted to neg bins;
     (b2) span(V) vs moved-frame restricted to pos bins;
     (c)  span(top-17 bulk bin profiles) vs span(17-frame);
     bars for IDENTIFIED (machine-level closure, frozen): max
     angle <= 1e-6 rad on (b1) AND (c).  Angles far from 0 =
     the honest burial, typed with the full tables.  CONTRAST
     controls: the foreign frame (quadruple {2,3,5,11}, frozen
     witness) and the scramble-load generators (seed 1, deployed
     softport convention) -- the truth-vs-control angle gap is
     the information census of the bridge (measured, typed; if
     truth and controls are indistinguishable AND far from 0 the
     bridge carries no displacement information -- typed).

 S5  CHARACTERS: sigma acts on the 12 moved divisors by the
     census 3-cycle (class (3,5,7,2); the character CONTENT is
     chirality-independent); the induced permutation T on the
     moved frame; exact isotypic projectors Pi_j = (1/3) sum_m
     om^{-jm} T^m in coefficient space; for each displacement
     generator, the least-squares coefficients on the moved frame
     split into (triv, om, ombar) energies (frame non-orthogonal:
     fractions normalized over the three isotypic images, typed);
     the moved sector's exact prediction is the regular-rep share
     2/3 nontrivial; bar for IDENTIFIED: aggregate nontrivial
     share in [0.5, 0.85].

 S6  MULTIPLICITIES: each of the top-17 bulk modes least-squares
     decomposed on the 17-frame; per-mode energy fractions on the
     sectors (moved, fixed, vacuum, pole) + the in-frame residual
     (how much of the bulk lies in the frame span at all -- the
     honesty number); effective multiplicities m_sector = sum of
     fractions; bar for IDENTIFIED: rounding gives exactly
     (12, 3, 1, 1) AND the median in-frame residual <= 0.3.

 S7  VERDICT (frozen): AUDIT-BROKEN (any S1/S2 regression fails)
     / MOVING12-IDENTIFIED (S4 angle bars AND S5 character bar
     AND S6 multiplicity bar) / MOVING12-DIMENSION-ONLY (the
     honest burial: same dimensions, different spaces -- the
     angle/multiplicity/character tables typed).

Sources (read-only): pole_port_kappa_probe (build_rung,
feshbach_pole, pole_transform_closed), softport_cauchy_probe
(contractor, LAM1_REFS, displacement construction conventions),
divisor210_canonicity_probe results (census classes, cited),
v845 register conventions.  Float64 SVD/eigh; the register side
exact integer.  NO RH claim; report only.

     (f1,f2,f3,a) -> (f3,f1,f2,a); q* = wt(iota)/2 mod 2 (the
     v845 lift identity, cited); unique anchor (sigma-fixed,
     q*=1) = A; admissible bases 6 ordered / 2 axis sets, weld-
     compatible 3 / 1; R3 (anchor -> 2) survivors modulo the
     weld gauge C3 = <sigma> (G3 from the canonicity run, cited)
     = EXACTLY the two classes chi+ = (3,5,7,2), chi- =
     (3,7,5,2).  Any fail => CENSUS-BROKEN.

 S2  READOUT REGRESSIONS (dw/wr read-only): the v1 extremal ref
     s_min(kz9, a, r2) = 8.68463e-01 +- 1e-5; Herglotz Im m > 0
     and passivity |r| < 1 on ZFIX, the spectral grid and the
     phase window; my inline total-phase-variation == the repair
     probe's readouts()["s_C"] to 1e-12 (the readout is the
     deployed one).  Any fail => READOUT-BROKEN.

 S3  THE BLINDNESS WARD (structural, must FIRE): the sigma-LESS
     chirality machines U0_chi(tau) = WH diag(i^wt)
     diag(d_chi^{-i tau/2}) are exactly conjugate under the bit
     transposition Pi = (F2 <-> F3), which fixes the vacuum port
     and the parity readout w2 -- so the loaded scalar transfer
     is IDENTICAL for chi+ and chi- (matrix ward <= 1e-13;
     loaded scalars <= 1e-12 on the whole phase window).  ANY
     phase readout that does not couple the family-cycle letter
     sigma to the weights is PROVABLY chirality-blind; the
     decider below therefore wires sigma in.  (Also typed: the
     fixed-sector divisors 1, 2, 105, 210 are chirality-equal.)

 S4  THE DECIDER (frozen decision rules):
     D1 REGISTER ORIENTATION FUNCTIONAL (exact): for each of the
        4 free 3-orbits O with root v0 = min(O) and x_k =
        log d_chi(sigma^k v0), X1(O) = sum_k x_k om^k with om =
        e^{2 pi i/3}; Phi_reg(chi) = sum_O Im(X1^3).  WARDS:
        antisymmetry Phi_reg(chi+) = -Phi_reg(chi-) (rel 1e-12);
        re-rooting (v0 -> sigma v0) invariance (the C3 gauge).
     D2 KMS-ORIENTATION CRITERION (frozen): the deployed modular
        phases are e^{-i w tau/2} with tau >= 0 on the dual grid
        (redheffer design (b)); the KMS-compatible chirality :=
        the one with Phi_reg(chi) > 0 (positive spectral winding
        of the log-weights along the cycle, om = e^{+2 pi i/3}
        paired with tau >= 0).  TYPED HONESTLY: this pairing of
        two sign conventions is a CONVENTION BRIDGE unless the
        machine leg (D3) independently selects the same
        chirality; D2 alone cannot decide.
     D3 MACHINE LEG (the sigma-wired loaded phase readout): the
        chirality machine U_chi(tau) = WH diag(i^wt) P_sigma
        diag(d_chi^{-i tau/2}) (P_sigma = the deployed family
        cycle on labels; the ONLY difference between chi+ and
        chi- is the weight assignment); port = vacuum slot
        (U[0,0] = 1/4, warded); load = the deployed divisor
        tower (kz 9, variant a, dw read-only), r(i y) on the
        frozen window y in YPH (33 points), coupling tau_j = y_j
        (frozen); f_j = w2' Vt_chi(r_j, tau_j) w2;
        Phi_mach(chi, load) = sum_j arg(f_{j+1}/f_j) (signed
        winding), V(chi, load) = sum_j |arg(f_{j+1}/f_j)| (total
        variation).  Loads: truth, Epstein (kn.lambda_eps),
        scramble (frozen LCG seed 12345, dw convention).
        FROZEN DECISION: the machine SEES the chirality iff
        |Phi_mach(chi+) - Phi_mach(chi-)| >= 1e-3 rad on truth;
        disc_ok(chi) iff V(chi, eps)/V(chi, truth) outside
        [1/1.5, 1.5] AND V(chi, scr)/V(chi, truth) outside
        [1/1.5, 1.5]; the machine DECIDES iff exactly one
        chirality has disc_ok; then winner_mach = that
        chirality.
 S5  SCRAMBLED-REGISTER CONTROL (must fire): LCG-permute the 12
     moved divisor values (seed 12345): the lattice
     multiplicativity d(v XOR w) = d(v) d(w) on disjoint
     supports BREAKS (count > 0 violated pairs), and the machine
     readout moves (rel >= 1e-6) -- the decider consumes the
     register structure, not just 12 numbers.

 S6  VERDICT (frozen precedence): CENSUS-BROKEN / READOUT-BROKEN
     / WARD-DEAD (S3 or S5 fails to fire) / then:
     - machine decides AND winner_mach == KMS winner (D2) ->
       CHIRALITY-DECIDED (named winner; criterion: machine
       discrimination + KMS orientation agree);
     - machine decides AND winner_mach != KMS winner ->
       CHIRALITY-INCONSISTENT (typed);
     - machine does not decide (both disc_ok, or neither, or
       the machine does not even see the chirality) ->
       CHIRALITY-DEGENERATE (the freedom is real gauge at the
       deployed-machine level; D2 alone is a convention bridge,
       typed, NOT a decision).

Sources (read-only): divisor210_canonicity_probe (census, cited
counts), divisor_weyl_port_probe (towers, closure blocks, v1
refs), weyl_readout_repair_probe (Load, readouts, YPH, ZFIX),
redheffer_colligation_probe (walsh16, hamw),
krein_normalform_probe (lambda_eps), v845 register conventions.
NO RH claim; report only.

ADDENDUM v2 (typed after run 1; run-1 numbers unchanged, no
decision bar moved -- the amendment REPAIRS a mis-calibrated ward
and TYPES two structural findings the run produced):
 (1) MEASURED STRUCTURAL FACT: Phi_reg vanishes IDENTICALLY (both
     chiralities, to 1e-15).  Mechanism, verified exactly: the
     Moebius complement d -> 210/d pairs the four free orbits
     (weight-1 <-> weight-2 at fixed anchor bit) with REVERSED
     cycle orientation, so X1(O')^3 = -X1(O)^3 per pair and the
     orbit sum cancels for EVERY multiplicative weight
     assignment.  The register carries no intrinsic scalar
     orientation of this type; the D2 KMS criterion is therefore
     VACUOUS (winner undefined), typed.  The v1 antisymmetry
     ward divided by |Phi_reg| ~ 1e-15 and failed on float noise
     although antisymmetry holds trivially; v2 wards: absolute
     antisymmetry |Phi+ + Phi-| <= 1e-12, re-rooting invariance
     absolute <= 1e-12, and the NEW exact complement-cancellation
     ward |X1(O)^3 + X1(O')^3| <= 1e-12 per pair.
 (2) MEASURED STRUCTURAL FACT: the sigma-wired QUADRATIC readout
     is also chirality-blind (|dPhi| ~ 1e-15): w2' M w2 =
     w2' M^T w2 sees only the symmetric part of the machine, and
     cycle reversal is exactly transposition up to the
     Pi-conjugation that fixes port and readout (U_-^sigma =
     Pi (sigma^{-1}-machine) Pi^T, and the transposed machine
     has blocks (A^T, C^T, B^T) whose closure scalar under ONE
     readout vector is identical).  v2 adds the ward for this
     equality and a REPORT-ONLY diagnostic: the asymmetric
     two-vector readout w2' Vt w1 (r2 left, r1 right, both
     deployed) -- measured for chirality response and typed, NOT
     verdict-bearing (post-run diagnostic).
 (3) Verdict logic under a vacuous D2: CHIRALITY-DECIDED would
     require the machine leg to decide alone (named as machine-
     only); with D3 measured blind the verdict is
     CHIRALITY-DEGENERATE either way.
