r"""v955 -- PRIME.PORT.TAU.SYMBOLIC.01 (round 224, EXECUTED at the finite-identity level) + PRIME.PORT.LAX2.CONDITIONED.01 (round 225, ADJUDICATED: LAX1_H_EXACT) + PRIME.PORT.HIROTA.SIGN.01 (round 226, DECIDED: HIROTA_TODA_EXACT + WALL_EQUIVALENT): THE FINITE INTEGRABLE DICTIONARY OF THE WALL -- the wall determinant IS the exact IIKS Fredholm tau function of the discrete 2x2 problem, the h-direction carries an exact PREDICTIVE degree-1 Lax dynamics, and the bilinear Toda/Hirota structure is the exact Hankel dictionary of the SIGNED DEFECT MEASURE mu - nu whose quasi-definiteness IS the wall.  ONE module from three probes (18/18 + 15/15 + 17/17 first-pass gates, zero fails; discovery probes tau_symbolic_probe.py, lax_conditioned_probe.py, hirota_sign_probe.py, rounds 224-226, notes DL/DLI/DLII, 2026-08-23, re-run identically at promotion, embedded BYTE-EXACT and executed verbatim; the v881-promoted port_integrable_kernel_probe.py embedded as read-only library).  (1) THE TAU IDENTIFICATION (round 224, verdict TAU_IIKS_EXACT): on all five heavy rungs (kz 9/12/13/26/40, h = 151..591, ports 13..54) -- (a) Sylvester as a FULL characteristic identity det(I - s Q_state) = det(I - s E_node) on the whole s-grid (log-space <= 1e-9); (b) the s-family of the wall carries the s-DRESSED port: det(I - sE) = det(I - sR) det(I - s D_P(s)) with D_P(s) = P + sX(I - sR)^{-1}X^T EXACT (Schur algebra), while the fixed-kernel family det(I - s D_P) is a DIFFERENT family (alias gap 0.06..0.20 at s = 0.5, named and blocked) that meets the wall exactly at s = 1; (c) the contract's declared death spot dissolves: E_ii equals the confluent limit of the SAME generator formula (classical CD confluence, dev <= 3.2e-13 on every rung) -- the kernel is CONSTRUCTED, never completed from displacement (CASE 1, no divisor needed); (d) the dressed resolvent is integrable AGAIN (IIKS dressing identity <= 7.9e-13) and the G31 surprise: the sealed Schur transport Fhat = F_p + X(I - R)^{-1}F_b reproduces the D_P displacement EXACTLY (<= 1.5e-13) -- the dressed port generators are source-explicit in closed form, D_P is itself a fully explicit IIKS kernel; (e) the Fredholm variational identity d log det(I - sK(t)) = -s Tr[(I - sK)^{-1} dK] holds in TWO independent times (scaling s AND a sealed weight deformation; FD-vs-trace <= 1.4e-9) with mixed-partial closedness (<= 4.3e-6, FD-limited) -- FREDHOLM_IIKS_EXACT with the JMU form carried on a true two-parameter family; (f) the relative tau transfer log tau_{h+1} - log tau_h = log det[I - (I - K_up)^{-1} DeltaK] (zero-padded union embedding, no division by tiny determinants) holds EXACT in log space over collapses of -8.88/+2.11/-212.84/-195.50 log units (devs <= 3.4e-12) across all dimension changes (184 <-> 151 <-> 168 <-> 364 <-> 591 nodes).  CONTROLS INVERTED PER CONTRACT: Epstein and scramble SATISFY the algebra (3.1e-15/3.5e-13) and differ in the VALUE sign tau(1) = -1 -- the IIKS structure is operator geometry, the arithmetic sits in the value; no leg consumes I - K >= 0, wall positivity or certified signs (CIRCULAR_TAU guard green); all four must-fail mutations fire.  (2) THE LAX DEGREE ADJUDICATION (round 225, split verdict LAX1_H_EXACT + RELATIVE_RANK2_EXACT / NO-FIXED-DEGREE(s) / RELATIVE_NO_COMMON_CARRIER(across)): the h-step is EXACTLY rank one (E_{h+1} = E_h + F F^T, dev <= 2.9e-16) and the dressed relative kernel has displacement rank EXACTLY 2 with explicit generators (<= 7.5e-13, sigma3/sigma1 <= 2.8e-14); the degree-1 source-chain connection F_{h+1} = ((Y - al_h)F_h - be_{h-1}G_h)/be_h predicts the next generator pair on the SEALED blind rungs (kz 26/40) to 3.4e-16 and the next tau step via the Christoffel scalar log(1 - F^T(I - E_h)^{-1}F) to 3.2e-11 -- the next RHP, tau_{h+1} and its sign are NEVER consumed; zero curvature holds identically for the closing time pair on MAIN, EPSTEIN and SCRAMBLE (transfer-coefficient t-drift EXACTLY 0.0; FD <= 2.6e-10) -- the algebra is world-blind, the arithmetic only moves the value; the small dynamics alone (Sherman-Morrison + Christoffel scalar, the big determinant never re-solved) transports the last 30 h-steps over -26.62/-38.38 log units to 7.3e-12/8.1e-9, sign-tracked on scramble; mpmath wards at dps 80/120 (4.3e-79/3.5e-119).  THE NEGATIVES, TYPED NOT HIDDEN: the s-time has NO fixed degree (basis-invariant eps_d plateaus at 0.34..0.60 over d = 0..6 -- CONDITIONING_ONLY; the old 0.244 degree-2 proximity was a regressive shadow) and across rungs there is NO common carrier (node positions disagree at shared uf indices by up to 1.212 -- RELATIVE_NO_COMMON_CARRIER + TAU_TRANSCRIPTION(across)); FIXED_DP_ALIAS guard green (the frozen r224 gaps reproduce within 5 percent).  The word "2" was indeed a hypothesis: the true minimal degree in the closing direction is 1, and the closing direction is h, not s.  (3) THE TODA/HIROTA DICTIONARY (round 226, verdict HIROTA_TODA_EXACT + WALL_EQUIVALENT with explicit SIGNED_TODA X - Y structure): with Q_n(jk) = <p_j, p_k>_nu and Sylvester tau_n = det(I - E_n) = det(I - Q_n) (r224), the matrix I - Q_n IS the Gram of the SIGNED DEFECT MEASURE mutilde = mu - nu in the mu-orthonormal basis, hence tau_{w,n} = D_n(mu - nu)/D_n(mu) (Hankel-determinant QUOTIENT), the Christoffel scalar is r_n = h_n(mu - nu)/h_n(mu) (monic norm-square ratio), and the Hirota coefficient H_n = r_n/r_{n-1} = gammahat_n/gamma_n comes from a scaled SIGNED Stieltjes recursion consuming ONLY node positions and weights of both comb zones -- NO determinant, NO tau, NO next RHP in the coefficient path (worst rel 1.7e-11 at full depth n = 184 to 4.0e-8 at full depth n = 591; dps-60 ward drift 1.4e-9 with exact signs, dps-80 toy 1.0e-79); the exact flag Hirota identity in Schur innovation form (<= 1.3e-13; corollary: the LAST flag is the most dangerous -- no earlier principal minor flips first); the Riccati second half r_{n+1} = 1 - a_n - b_n^2/r_n EXACT (<= 4.3e-12) with the Cauchy-Schwarz route MEASURED AND CLOSED (a_n/r_n up to 2.12 > 1: the current-state induction does NOT close from Cauchy-Schwarz alone); THE SIGN ADJUDICATION (the round's value): gammahat_n > 0 for all n <=> all h_n(mu - nu) > 0 <=> QUASI-DEFINITENESS of the signed defect measure <=> the wall -- WALL_EQUIVALENT, with h_n(mutilde) = ||pi_n||_mu^2 - ||pi_n||_nu^2 an explicit X - Y of two positive norms; MAIN carries ALL 184 r_n > 0 (min +0.3666, the full degree chain of the wall measured positive for the first time), EPSTEIN 55 flips (first n = 25), SCRAMBLE 37 (n = 21), SMOOTH 4 (n = 27); HIROTA_CONE_GO was NOT reached (the reviewer's expected base verdict, now a theorem instead of a suspicion); all four must-fails fire (incl. the TAU_DEFINED trap and INDEX_ALIAS).  THE NEW COORDINATE IS SUBSTANTIVE: "RH wall inside a window" now reads "the signed measure mu - nu behaves like a positive measure through degree n_max" -- a classical moment-problem statement about the von Mangoldt double zone, with r_n the correct local Fermi-edge observable (source-canonical, LAX1-predictable, numerically stable).  CLAIM SPLITTING (note DLI, carried to the ledger by this promotion): the finite set is PRIME.PORT.TAU.FINITE.IIKS.01 [E] (Sylvester characteristic + confluent diagonal + explicit generators + Fredholm/JMU identity + relative tau transport + the degree-1 h-dynamics + the Toda dictionary); the sign question stays honestly open as PRIME.PORT.TAU.NOPOLE.COFINAL.01 [O] (tau_h(1) > 0 cofinally, i.e. no Malgrange divisor up to s = 1); the v883-registered umbrella PRIME.PORT.TAU.01 [O] is EXECUTED at the finite-identity level (the general-h statements are classical theorems -- Sylvester, Schur, CD confluence, IIKS dressing -- instantiated on the actual builders) and stays formally open [O] for the fully symbolic arbitrary-h statement.  The mincut stays base 4 / refined 5 (WALL_EQUIVALENT moves no edge -- expected); no other marker moves.  NOT evidence for or against the Riemann Hypothesis in either direction.  NO RH CLAIM.

r"""port_integrable_kernel_probe -- PRIME.PORT.INTEGRABLE.01
(EXPLORATION ONLY, experiments/; round 39 task 3 of the 2026-08-09
external review: the integrable-kernel form of the Krein form and
the displacement structure of the DRESSED port operator,
2026-08-09).

THE FORMS (frozen): with J = Q X Q^T (Gauss diagonalization),
u = Q^T e_{h-1}, v = Q^T r (round-38 generators):
  (i)  INTEGRABLE KERNEL: Delta-hat_{ij} = b_h (u_i v_j - v_i
       u_j)/(x_i - x_j) for i != j -- the full-rank Cauchy/
       integrable-kernel class (numerator and denominator each
       antisymmetric; the review's corrected reading of the
       rank-2 displacement);
  (ii) PORT BLOCK EXACT: the UNdressed port block P =
       sqrt(nu) K_CD sqrt(nu) restricted to port nodes has EXACT
       displacement rank <= 2 wrt Y = diag(y_port) (the CD
       formula: (y_m - y_m') P_mm' collapses to two generators);
  (iii) DRESSED DISPLACEMENT (the open question): does [Y, D_P]
       with D_P = P + X (I-R)^{-1} X^T stay low-rank?  The
       dressing is a product of kernels -- no exact collapse is
       known; MEASURE the singular-value profile and type it.

FROZEN PROTOCOL (2026-08-09; heavy rungs kz {9, 12, 13, 26, 40};
controls kz 9):

 I1  INTEGRABLE FORM: off-diagonal identity rel error (Frobenius,
     off-diag part) <= 1e-8 on all heavy rungs.

 I2  PORT-BLOCK RANK 2: sigma_3/sigma_1 of [Y, P] <= 1e-10 on all
     heavy rungs (EXACT low displacement, CD-forced).

 I3  DRESSED PROFILE (typed): effective rank of [Y, D_P] at the
     1e-6 sigma_1 threshold per rung; typed DRESSED-LOW iff the
     effective rank is <= 6 on ALL heavy rungs (the dressing
     preserves near-integrability), else DRESSED-HIGH (the
     dressing genuinely thickens the displacement -- honest
     either way; the sigma profile printed).

 C   CONTROLS (kz 9, must fire): edge crossed on both (min gap <
     0); the algebraic identities I1/I2 PERSIST (algebra, not
     arithmetic -- re-typed).

KILLS: K1 identity I1 breaks -> INTEGRABLE-BROKEN; K2 the exact
port-block rank-2 breaks -> CDRANK-BROKEN; K3 controls do not
fire -> CONTROL-DEAD.

VERDICT (frozen enum): INTEGRABLE-CONFIRMED (+ typed I3
sublabel) / INTEGRABLE-BROKEN / CDRANK-BROKEN / CONTROL-DEAD.

NO RH claim.  Firewall: no zeros, no prime-table oracles (AST
scan); v563 READ-ONLY; RNG only in the declared scramble control;
writes nothing but stdout.  No marker moves.

Sources (read-only): v563_paper2_readouts; round-38 chain
(cd_pick_scalarization / port_schur_reduction, declared inputs).

r"""tau_symbolic_probe -- PRIME.PORT.TAU.SYMBOLIC.01 (round 224):
is the wall determinant the tau function of the discrete 2x2 IIKS
problem for arbitrary finite h -- or was a rank-two displacement
structure mistaken for a tau function?

EXPLORATION ONLY (2026-08-23).  experiments/ level: NO promotion, NO
ledger row, NO marker moved, NO gate closed or narrowed, NO RH CLAIM
in either direction.  This round executes the v883-registered
symbolic contract (PRIME.PORT.TAU.01 [O]) at the finite-identity
level demanded by the reviewer's contract.

OBJECTS (v881 lane, verbatim builders): the Carleson node Gram
E_ij = sqrt(v_i v_j) K_h(y_i, y_j) with the CD kernel of the
mu-side chain; port split (lowest tau-decile nodes) E = [[P, X],
[X^T, R]]; the dressed port D_P = P + X(I - R)^{-1} X^T; the node
diagonal Y.  SOURCE GENERATORS (CD form, explicit): F_i = sqrt(v_i)
p_h(y_i), G_i = sqrt(v_i) p_{h-1}(y_i), so that EXACTLY
    (y_i - y_j) E_ij = b_h (F_i G_j - G_i F_j).

LEG A -- DETERMINANT PROVENANCE WITHOUT ALIAS:
  (A1) Sylvester as a FULL characteristic identity:
       det(I - s Q_state) == det(I - s E_node) for the whole
       s-family (slogdet at a sealed s-grid; Q_state = A*A,
       E = AA* with A = V^{1/2} P_h -- the r223 objects).
  (A2) THE s-FAMILY OF THE WALL NEEDS THE s-DRESSED PORT (this
       round's sharpening, exact Schur algebra):
       det(I - sE) == det(I - sR) det(I - s D_P(s)),
           D_P(s) := P + s X (I - sR)^{-1} X^T,
       and the FIXED-kernel family tau(s) = det(I - s D_P) is a
       DIFFERENT family that meets the wall exactly at s = 1
       (both gated; the naive insertion of the fixed D_P into an
       s-flow would be an alias -- named and blocked).
  KILL DETERMINANT_PROVENANCE_FAIL if either identity breaks.

LEG B -- DIAGONAL COMPLETION (the contract's declared death spot,
dissolved honestly): the kernel is CONSTRUCTED, never completed
from displacement; and the diagonal of E is EXACTLY the confluent
limit of the SAME generator formula (classical CD confluence):
    E_ii = v_i sum_{k<h} P_k(y_i)^2
         = v_i b_h (p_h'(y_i) p_{h-1}(y_i) - p_{h-1}'(y_i)
                    p_h(y_i))
(derivative chain by the differentiated three-term recursion;
gated to 1e-10 on every rung).  CASE 1 (confluent completion)
holds for E; for D_P the diagonal is EXPLICIT BY SCHUR ALGEBRA
(typed).  The elementary diagonal-divisor factorisation
det(I - sK) = prod(1 - s a_i) det[I - s(I - sA)^{-1} K_off] is
gated as exact algebra (available if ever needed; sign of the
divisor recorded).

LEG C -- THE DISCRETE RHP, BUILT: dressed generators
F(s) = (I - sE)^{-1} F, G(s) = (I - sE^T)^{-1} G; the resolvent
Rres = sE(I - sE)^{-1} must be INTEGRABLE AGAIN:
    (y_i - y_j) Rres_ij == s b_h (F_i(s) G_j(s) - G_i(s) F_j(s))
(the IIKS dressing identity; gated at sealed s on every rung and
on the worlds).  Existence <=> invertibility is carried by the
determinant (algebra); PORT INHERITANCE: the sealed transported
generators Fhat = F_p + X(I - R)^{-1} F_b, Ghat likewise, must
reproduce [Y_p, D_P] (the Schur displacement inheritance) --
measured, both transport conventions disclosed.

LEG D -- FREDHOLM VS JMU: the variational identity
    d log det(I - sK(t)) = -s Tr[(I - sK(t))^{-1} dK/dt]
gated by central finite differences in TWO independent times (the
scaling s and a sealed weight deformation t: v -> v(1 + t w) with
frozen profile w), plus CLOSEDNESS: the mixed partials
d2/ds dt log tau agree from both orders (FD cross ward).  Type
FREDHOLM_IIKS_EXACT on success; JMU_FORM_EXACT only with the
two-time closedness carried.

LEG E -- THE RELATIVE TAU TRANSFER (the handover object): for
adjacent full rungs with the ZERO-PADDED embedding K_up of K_h on
the union index set,
    log tau_{h+1} - log tau_h ==
        log det[I - (I - K_up)^{-1} (K_{h+1} - K_up)]
EXACT in log space (slogdet; no division by tiny determinants),
all dimension changes handled by the padding (I - K_up is block-
identity on new indices).  Gated on consecutive heavy pairs.

CONTROLS, INVERTED PER THE CONTRACT: Epstein and scramble must
SATISFY every algebraic identity (the IIKS structure is operator
geometry; the arithmetic sits in the VALUE tau(1)) -- gated.
MUST-FAIL mutations (each must break loudly): (m1) mutate one
generator row; (m2) mutate one diagonal entry (confluence breaks);
(m3) rank-one truncation (drop the G-term); (m4) node collision
guard (duplicate node -> Cauchy denominator guard fires).

SEALED VERDICTS: TAU_IIKS_EXACT / TAU_IIKS_WITH_EXPLICIT_DIVISOR /
DIAGONAL_SIGN_OPEN / DISPLACEMENT_ONLY / TAU_ALIAS_ONLY /
CIRCULAR_TAU.  No leg consumes I - K >= 0, wall positivity or
certified-rung signs (CIRCULAR_TAU guard: the identities are gated
on indefinite controls too).

RECORD TABLES (frozen from calib_ts_pass1.log, 18/18 FIRST PASS at
the pre-freeze SHA 407bc4933bf5b9b6):
CAL_VERDICT = TAU_IIKS_EXACT (finite-identity level).  Key numbers
(all five heavy rungs kz 9/12/13/26/40, h = 151..591, ports
13..54): Sylvester + s-dressed Schur family exact on the whole
s-grid; fixed-vs-dressed alias gap 0.06..0.20 at s = 0.5 (blocked);
confluent diagonal <= 3.2e-13; IIKS dressing identity <= 7.9e-13;
G31 SURPRISE: the sealed Schur transport Fhat = F_p + X(I-R)^{-1}
F_b reproduces the D_P displacement EXACTLY (devs <= 1.5e-13) --
the dressed port generators are source-explicit in closed form;
variational identity (s, t) <= 1.4e-9, mixed-partial closedness <=
4.3e-6 (FD-limited); relative transfer exact over collapses of
-8.88, +2.11, -212.84, -195.50 log units (devs <= 3.4e-12, no
tiny-determinant division); Epstein/scramble SATISFY the algebra
(3.1e-15 / 3.5e-13) with sign tau(1) = -1 (value differs, algebra
holds -- the inverted control of the contract); all four must-fail
mutations fire.  The general-h statements are classical theorems
(Sylvester, Schur, CD confluence, IIKS dressing) instantiated on
the actual builders; the v883 [O] promotion decision stays with
the lane.  AMENDMENTS: NONE after freeze.

WHAT IS BUILT AND GATED: S0 G01 firewall + G02 predefinition; S1
leg A G10-G12; S2 leg B G20-G21; S3 leg C G30-G31; S4 leg D
G40-G41; S5 leg E G50; S6 controls G60-G61 + pricing G70-G71 +
G80 verdict + G99 runtime.  DETERMINISM: no randomness (scramble
seed frozen); run2 identical modulo wall-clock tokens.

NO RH CLAIM IN EITHER DIRECTION.  NOT evidence for or against RH.

r"""lax_conditioned_probe -- PRIME.PORT.LAX2.CONDITIONED.01
(round 225): does the exact IIKS/JMU family of round 224 possess a
source-canonical connection of FIXED FINITE DEGREE that predicts
the relative tau transport -- without consuming the next
determinant or the next RHP?  The word "2" is a hypothesis; this
round adjudicates the minimal degree and the minimal rank at the
same time.

EXPLORATION ONLY (2026-08-23).  experiments/ level: NO promotion,
NO ledger row, NO marker moved, NO RH CLAIM in either direction.

LEG A -- FREEZE THE CORRECT FAMILY (r224 leg-A sharpening carried
as a live must-fail): tau_h(s) = det(I - sE_h) = det(I - sR_h)
det(I - s D_P(s)) with D_P(s) = P + sX(I - sR)^{-1}X^T; the FIXED
kernel s D_P(1) must HIT at s = 1 (<= 1e-9) and must MISS at
s = 0.5 by exactly the frozen r224 gaps (5 percent tolerance):
kz 9/12/13/26/40 -> 6.00e-2/1.95e-1/1.70e-1/1.71e-1/1.89e-1.
KILL FIXED_DP_ALIAS on confusion.

LEG B -- THE RELATIVE OPERATOR, MINIMAL RANK ADJUDICATED IN TWO
TRANSPORT TYPES (the round's structural decision):
  (B-within) WITHIN-RUNG h-step (same window, same measure): the
     increment is EXACTLY rank one, E_{h+1} = E_h + F_h F_h^T
     (machine zero), so Delta K is rank 1 and the dressed relative
     kernel Krel = (I - E_h)^{-1} F F^T has displacement
     [Y, Krel] of EXACT RANK 2 with the explicit generator pair
     left = M^{-1}(b(G^T M^{-1}F) F - b(F^T M^{-1}F) G + YF),
     right = F  and  left2 = M^{-1}F, right2 = YF (verified
     <= 1e-10): RELATIVE_RANK2_EXACT holds for the h-transport.
  (B-across) ACROSS-RUNG (kz -> kz'): MEASURED STRUCTURE FACT: at
     shared uf indices the node POSITIONS DISAGREE between windows
     (max |Delta y| ~ 3.6e-1, median ~ 1e-1) -- there is NO common
     node operator Y on the uf-matched union, hence NO common-
     carrier IIKS displacement for the across-rung Delta K.  The
     disjoint-union 4-generator form exists but is BLOCK-TRIVIAL
     (2+2, zero coupling; the tau ratio degenerates to the plain
     quotient).  Typed RELATIVE_NO_COMMON_CARRIER(across) -- the
     honest reason the old degree-2 regression could only ever
     shadow (its 0.244 was a fit across non-matching carriers).

LEG C -- CANONICAL CONDITIONING, BASIS-INVARIANT PROJECTION ERROR
(not cosmetic whitening): Krylov spaces K_d = span{Fcal, Y Fcal,
..., Y^d Fcal} with the TRUE node-measure metric G = B^* V B,
whitened by the unique positive root G^{-1/2} (eigen-cutoff
1e-13 relative, effective dimension reported).  eps_d =
||(I - Pi_d) xdot||_V / ||xdot||_V, scanned d = 0..6, separately
for (1) the s-time xdot = d/ds F(s) = (I - sE)^{-2} E F at
s = 0.6 against the DRESSED pair (F(s), G(s)); (2) the sealed
r224 index-cosine weight time; (3) a position-linear weight time
v -> v(1 + t y) (closes at degree 1 EXACTLY, disclosed); (4) the
within-rung h-transport (closes at degree 1 EXACTLY: the three-
term recursion IS the connection).  HARD GATE: an exact degree
needs eps_d <= 1e-10 on ALL development and blind rungs; an
eps_2 = O(1e-1) that merely looks nicer after whitening is
CONDITIONING_ONLY and is typed as such.

LEG D -- THE CONNECTION MUST PREDICT, NOT TRANSCRIBE: on the BLIND
rungs (kz 26, 40; development kz 9/12/13) the degree-1 connection
    F_{h+1} = ((Y - al_h) F_h - be_{h-1} G_h)/be_h,
whose coefficients consume ONLY the source Lanczos chain (nodes
and weights), must predict the next generator pair to <= 1e-10;
and the tau step must follow from the CURRENT solution alone:
    log tau_{h+1} - log tau_h = log(1 - F^T (I - E_h)^{-1} F)
(matrix determinant lemma; <= 1e-8).  FORBIDDEN and not consumed:
the next RHP, tau_{h+1}, its sign, any holdout fit.

LEG E -- ZERO CURVATURE: for the two exactly-closing times (the
h-step with transfer coefficients from the source chain, and the
position-linear weight time with A_t = Y/2) the curvature vanishes
IDENTICALLY: the transfer polynomial L_h(Y) commutes with Y/2 and
its coefficients are t-independent (the nu-side deformation never
touches the mu-side chain); gated numerically (FD in t vs Y/2
action on the transported pair) on MAIN, EPSTEIN and SCRAMBLE --
the algebra must be world-blind, the arithmetic only moves the
value.  The s-time has NO fixed-degree connection (leg C measures
it), so the ideal (s, t) curvature is unreachable -- typed, not
hidden.

LEG F -- TAU FROM THE CONNECTION (anti-transcription): the last 30
h-steps of the wall are transported by the SMALL DYNAMICS alone
(state = current resolvent; Sherman-Morrison update + Christoffel
scalar per step; the big determinant is never re-solved) and must
reproduce the slogdet telescope <= 1e-8 on a development AND a
blind rung AND (sign-tracked) on scramble.  ACROSS-RUNG: the
-212.84 / -195.50 log-unit jumps have NO common carrier (leg B),
so their transport still consumes the full union resolvent: typed
TAU_TRANSCRIPTION(across) -- named, not claimed.

HIGH-PRECISION WARD: an mpmath dps = 80 and dps = 120 toy instance
(m = 12 nodes, deterministic toy comb, full chain) re-verifies the
rank-1 step, the Christoffel scalar, the determinant lemma and the
rank-2 relative displacement far below the f64 floor.

LAX4_RELATIVE_EXACT / LAXd_EXACT(d<=6) / CONDITIONING_ONLY /

and the across/s-direction typing separately.

t-lin and h-step close at degree 1 with eps <= 2e-14, index-cosine
time decays only to ~2e-2 at d = 6 (an index profile is not a
position polynomial); blind next-generator prediction 3.4e-16, tau
step 3.2e-11; zero curvature world-blind (t-drift of the transfer
coefficients EXACTLY 0.0 on MAIN/EPSTEIN/SCRAMBLE); 30-step

r"""hirota_sign_probe -- PRIME.PORT.HIROTA.SIGN.01 (round 226):
does the exact within-window degree dynamics of round 225 preserve
its own positive region -- and does the Hirota quantity possess a
SOURCE-PURE sign, or is its positivity the wall itself?

EXPLORATION ONLY (2026-08-23).  experiments/ level: NO promotion,
NO ledger row, NO marker moved, NO RH CLAIM in either direction.

INDEX FIREWALL (leg 0, binding for every symbol in this probe):
  w = outer window (kz rung), n = Jacobi/CD degree INSIDE the
  window, k = flag (leading principal size in node space), s =
  Fredholm coupling, t = position-linear weight time.  Mixing n
  and w must fail loudly (INDEX_ALIAS must-fail below); after
  RELATIVE_NO_COMMON_CARRIER (r225) the two directions are proven
  distinct.

ANTI-ALIAS DISCIPLINE (binding): TAU VALUES MAY VERIFY THE
FORMULA; TAU VALUES MAY NOT DEFINE ITS COEFFICIENTS.  Every
load-bearing coefficient below is generated from source data
(node positions and weights of BOTH comb zones) with NO
determinant evaluated anywhere in its construction.

THE ROUND'S THEOREM (leg D, discovered at pre-calibration and
frozen here): with Q_n(jk) = <p_j, p_k>_nu (state Gram of the
mu-orthonormal chain) and Sylvester tau_n = det(I - E_n) =
det(I - Q_n) (r224), the matrix I - Q_n is EXACTLY the Gram of
the SIGNED DEFECT MEASURE mutilde = mu - nu in the mu-orthonormal
basis, hence
    tau_{w,n} = D_n(mu - nu) / D_n(mu)
(ratio of Hankel determinants) and the Christoffel step scalar is
    r_n = tau_{n+1}/tau_n = h_n(mu - nu) / h_n(mu),
the ratio of MONIC orthogonal-polynomial norm-squares.  The
Hirota quantity is then the exact Toda dictionary
    H_n = r_n / r_{n-1} = gammahat_n / gamma_n,
        gammahat_n = h_n(mutilde)/h_{n-1}(mutilde),
        gamma_n    = h_n(mu)/h_{n-1}(mu) = be_{n-1}^2,
where gammahat is produced INDEPENDENTLY by a scaled signed
Stieltjes recursion on values over both node grids (source-pure;
no tau, no next RHP, no determinant).  Pre-test: rel 2.3e-15 at
n = 1 and 2.0e-12 at n = 183 (full window depth, f64).

LEG A -- RANK-ONE TAU CONTINUATION ON FLAGS: M_{n+1,k} = M_{n,k}
- s f_{n,k} f_{n,k}^T with f_{n,k} = P_k F_n; gated
tau_{n+1,k} = tau_{n,k} (1 - s f^T M^{-1} f) for k in a nested
flag set including full k (load-bearing) at s = 0.7 and s = 1;
plus the rank-one downdate ward: at full k, r_n > 0 <=> A_{n+1}
strictly positive definite (eigenvalue interlacing check) -- a
positive determinant cannot hide two negative eigenvalues.

LEG B -- THE EXACT FLAG HIROTA IDENTITY (Schur innovation form):
    tau_{n+1,k} tau_{n,k-1} - tau_{n,k} tau_{n+1,k-1}
        = -s tau_{n,k-1}^2 delta_{n,k}^2,
    delta_{n,k} = f_k - b^T B11^{-1} f_{1:k-1}   (the source-
canonical innovation of the new boundary component), gated on all
windows; corollary under current flag positivity:
tau_{n+1,k}/tau_{n,k} <= tau_{n+1,k-1}/tau_{n,k-1} -- THE LAST
FLAG IS THE MOST DANGEROUS (no earlier principal minor flips
first), gated on MAIN.

LEG C -- THE RICCATI SECOND HALF: with R_n = A_n^{-1}, a_n =
F_{n+1}^T R_n F_{n+1}, b_n = F_{n+1}^T R_n F_n, EXACTLY
    r_{n+1} = 1 - a_n - b_n^2 / r_n,
    r_n r_{n+1} = det [[r_n, b_n], [b_n, 1 - a_n]] =: det G_n,
gated; the normalized coordinate zeta_n = b_n / sqrt(r_n (1-a_n))
is measured (|zeta| < 1 profile on MAIN); the Cauchy-Schwarz
budget b_n^2 <= a_n (1 - r_n) gives r_{n+1} >= 1 - a_n / r_n,
positive iff a_n < r_n -- MEASURED: the ratio a_n / r_n decides
whether a current-state induction closes without a further source
relation.

LEG E -- SIGN-SOURCE ADJUDICATION (the round's value): the
source-pure Hirota coefficient gammahat_n is a DIFFERENCE
    h_n(mutilde) = ||pi_n||_mu^2 - ||pi_n||_nu^2
of two positive norms of similar order (gated as X - Y with both
sides computed); its positivity for all n <=> all r_n > 0 <=> the
wall <=> THE SIGNED MEASURE mu - nu IS POSITIVE-DEFINITE THROUGH
DEGREE n (quasi-definiteness of the defect measure -- the wall in
moment-problem coordinates).  No source-pure positive
representation of G_n was found; the Cauchy-Schwarz route needs
a_n < r_n which fails on the real ladder (measured).  VERDICT
TYPE: HIROTA_TODA_EXACT + WALL_EQUIVALENT (with the explicit
SIGNED_TODA X - Y structure); the reviewer's base verdict, now
carried by a theorem instead of a suspicion.

LEG F -- WORLDS AND MUST-FAILS: the algebra (legs A-D) must hold
on MAIN, EPSTEIN, SCRAMBLE and SMOOTH (fine positive quadrature
comb); the SIGN must separate: MAIN all r_n > 0 through the full
window; the controls flip (first flip index and flip count
reported).  MUST-FAILS (each loud): (m1) wrong Jacobi coefficient
(gamma index shifted); (m2) swapped recursion index in the
dictionary; (m3) INDEX_ALIAS: window w gammahat against window
w' tau chain; (m4) TAU_DEFINED trap: mutating one source weight
changes gammahat and breaks the dictionary (the coefficient is
moment-defined, not tau-defined).

HIGH-PRECISION WARD: mpmath dps = 60 full-depth signed recursion
on w = 9 re-derives the f64 gammahat chain (drift reported); toy
instance (m = 12) at dps = 80 verifies the dictionary with exact
determinants on both sides.

SEALED VERDICTS: HIROTA_CONE_GO / TODA_SIGN_SOURCE /
HIROTA_EXACT_WALL_EQUIVALENT / SIGNED_TODA / WINDOW_LOCAL_ONLY /
TAU_DEFINED / INDEX_ALIAS.

RECORD TABLES (frozen from calib_hs_pass1.log; two marginal-bar
amendments before freeze, disclosed: world bar 1e-4 because the
flip worlds run the signed recursion through near-degenerate
h-zeros, and DICT_BAR 1e-7 because the deepest window w = 40
accumulates ~4e-8 float error over 591 recursion + Sherman-
Morrison steps -- both covered by the dps-60/80 wards):
CAL_VERDICT = HIROTA_TODA_EXACT + WALL_EQUIVALENT (SIGNED_TODA
X - Y structure explicit).  Key numbers: flag continuation and PD
ward green on all five windows (deep-window lam_min down to
6.7e-7 tracks r_n > 0 exactly); flag Hirota <= 1.3e-13 with
monotone quotients everywhere; Riccati exact <= 4.3e-12, |zeta|
<= 0.65 inside windows, a_n/r_n max 2.115 (> 1: the Cauchy-
Schwarz induction does NOT close -- measured on all windows);
dictionary r_n = h_n(mu-nu)/h_n(mu) worst 1.7e-11 (w = 9, full
depth 184) to 4.0e-8 (w = 40, full depth 591), Hirota quotient
form one order better; worlds: MAIN all 184 r_n > 0 (min 0.3666),
EPSTEIN 55 flips (first n = 25, min -63.3), SCRAMBLE 37 flips
(first n = 21, min -147.6), SMOOTH 4 flips (first n = 27, min
-2.28) -- algebra world-blind, sign separates; h_0 = 3.699 -
0.226 (X - Y explicit); all four must-fails fire; dps-60
full-depth recursion drift 1.4e-9 with exact signs, dps-80 toy
ward 1.0e-79.  AMENDMENTS: NONE after freeze.
