r"""v959 -- PRIME.PORT.RHP.COUPLEDTAU.TERMINAL.01 (rounds 256-259, ADJUDICATED at the finite-identity level): THE COUPLED-TAU / TERMINAL-BUDGET DICTIONARY OF THE WALL -- the positive-prefix firewall and the exact 2x2 causal census, the coupled two-term tau recursion of the indivisible full-source object D = tau^aug/tau (with its bilinear Hirota-type corollary derived and gated in-module), the blind coefficient-field predictor that passes the frozen micro-falsifier on both sides, and the exact Schur budget telescope with its one-inequality terminal reduction.  ONE module from four probes (21/21 + 26/26 + 27/27 + 19/19 first-pass gates, zero fails; discovery probes baseborder_factorial_probe.py, coupledtau_probe.py, budget_anatomy_probe.py, parametrix_pass_probe.py, rounds 256/257/258/259, notes DLXXXVII/DLXXXVIII/DLXXXIX/DXC, 2026-08-24, re-run identically at promotion, embedded BYTE-EXACT and executed verbatim), plus the module-own exact section S0 (sympy-symbolic + exact rationals).  (S0) THE MODULE-OWN EXACT THEOREMS (fine types Identity/Formal): (S0.1) the coupled recursion tau_{n+1} = a_n tau_n, tau^aug_{n+1} = a_n tau^aug_n + b_n tau_n with a_n = c_n^2 h_n and b_n = -(c_n F_n)^2 implies the Riccati drain D_{n+1} = D_n - F_n^2/h_n for D = tau^aug/tau, symbolically and on a frozen exact-rational chain; b_n is a manifest negative square, source-sign-pure in every world.  (S0.2) THE BILINEAR TAU FORM (the canonical integrable corollary, derived algebraically from the recursion and gated): tau^aug_n tau_{n+1} - tau^aug_{n+1} tau_n = (c_n F_n)^2 tau_n^2 -- the Wronskian-type bilinear identity whose right side is a manifest square: the fiber increment is a positive tau cross-ratio, (tau^aug_n tau_{n+1} - tau^aug_{n+1} tau_n)/(tau_n tau_{n+1}) = F_n^2/h_n * (a_n tau_n / tau_{n+1}) collapses to the drain (symbolic + exact rationals, every step of the frozen chain).  (S0.3) THE TERMINAL REDUCTION + CONSEQUENCE GATE: with the r243 budget definition B = S_{N-2} + 5/7 (by construction), D_N = B - S_{N-1} = 5/7 - rho_{N-1}, hence margin D_N > 0 iff q_N = rho_{N-1}/(5/7) < 1 -- the ENTIRE fiber positivity is one terminal inequality (symbolic identity + exact rationals in both truth values).  (S0.4) THE CORNER-RAY / t* NORMAL FORM: B(t) = S_{N-2} + t*(5/7) makes the terminal pivot affine in t with slope exactly 5/7 and machine root t* = q_N -- the budget question IS a t*-coordinate in the r238 normal form (symbolic).  (S0.5) THE POSITIVE-PREFIX FIREWALL THEOREM (exact rationals): for a signed rational measure the prefix moment kernel H_p is positive definite iff the whole h-prefix h_0..h_{p-1} is positive (exact Sylvester chain, det H_p = prod h_i identity), the maximal positive prefix p_max is well-defined, a positive control measure types POSITIVE_PREFIX (p_max = N) while a frozen signed measure types INDEFINITE_CONTINUATION with an explicit negative border readout past p_max -- the r256 reviewer PSD core statement as exact algebra, with the must-fail firing.  (1) THE POSITIVE-PREFIX FIREWALL + THE 2x2 CAUSAL CENSUS (round 256, verdict EFFECTS_MIXED_COUPLEDTAU + INVERSION_IS_BASE_CONTAMINATION(f_neg=0.9311) + EPST: CONTROL_FIBER_IS_BASE_CONTAMINATION + SMOOTH_NULL_ANCHOR_OK + LEGS_BD_SKIPPED): the firewall type table -- MAIN pmax = 184 = N with ZERO negative modes (the ONLY positive-prefix world), SCRAMBLE pmax = 21 (37 negative modes), EPSTEIN 25 (55), SMOOTH 27 (4), all controls INDEFINITE_CONTINUATION; every prefix kernel numerically PSD (worst -lambda_min rel 5.7e-16) -- the reviewer PSD core theorem holds machine-level; the raw 2x2 census reproduces the r254 priors exactly (worst rel 4.9e-5; T_MM +4.334, T_MS +9.976, T_SM -0.928, T_SS -4.494; identity wards exactly 0) BUT the causal reading of the raw numbers WAS CONTAMINATED: Delta_base/Delta_int at full degree are bookkeeping over an indefinite kernel; on the causally clean surface (shared positive prefix n* = 21, both kernels PSD) the DOUBLE INVERSION -- Db* = -1.5e-6 (the base rotation is NULL on the clean prefix), Dbo* = -0.1759 (the border carries 81 percent of the prefix gap), Gap* = -0.216 with the raw border effect at the WRONG SIGN (-5.64 vs +8.83): the sealed LOAD_BEARING rule honestly does NOT fire, residual verdict COUPLEDTAU; legs B-D skipped by the sealed conditional (the exchange formula itself gated unconditionally exact, 1.2e-15); TWO CONTAMINATION DOWNGRADES ON RECORD: the r254 headline 'SCRAMBLE spectrally compact (K80 = 2)' is BASE CONTAMINATION (the exact h-sign mode split T_pos +3292.6 + T_neg -3297.1 = -4.494, net carried by the h < 0 mode space at 734x excess; the two carrying eigendirections sit at f_neg 0.93 in the h < 0 mode space) and the r253/r254 EPSTEIN fiber anomaly lives ENTIRELY in the indefinite continuation degrees k >= 25 (on the shared prefix the EPSTEIN border is fiber-IDENTICAL to MAIN, Dbo* = 1.3e-16) -- neither finding may be cited as a border/fiber discriminator any more; the alias must-fail is the core exhibit (T_SM negativity is 100 percent kernel property, lambda_min(G_SCR) = -2.9e6).  (2) THE COUPLED-TAU RECURSION (round 257, verdict COUPLED_RECURSION_EXACT + COCYCLE_LAW_FOUND + NO_EARLY_SEPARATION(0.84 dec) + MICROFALSIFIER_PASSED(blind, coefficient field) + NOPOLE_TREND(APPROACHING) + AUG_RAW_CROSSES_ONE + AUG_UNIT_CROSSES_ONE): the pair closes under the exact two-term recursion above (seeds tau_1 = h_0, tau^aug_1 = h_0 B - F_0^2; signed-log propagation vs direct bordered slogdets on all degrees/worlds at 1.2e-9 MAIN; anchor D_N = 5/7 - rho_{N-1} rel 4.8e-11; mp wards dps 220 THROUGH the SCRAMBLE flip); coefficient typology machine-gated: a_n reads the h-chain (its sign IS the world pivot sign), b_n is a negative square -- THE BASE ALONE CARRIES THE SIGN, THE BORDER ONLY NONNEGATIVE MAGNITUDE; the cocycle law breaks exactly at the control base flips 21/25/27 (the r256 firewall reproduced gradewise INSIDE the coupled dynamics); the ONE-LINE FORM of the whole problem: on MAIN (all h_n > 0) the drain is monotone through the entire free window (min rho 8.9e-10 at n = 180; head/bulk/tail shares 0.446/0.531/0.023) -- fiber positivity IS the budget inequality Sum(F_n^2/h_n) < B and wall positivity supplies the increment signs: base and fiber are coupled in ONE scalar law; THE FROZEN MICRO-FALSIFIER of PRIME.FREEMOMENT.POSITIVEPREFIX.01 is PASSED BLIND for the first time, at the coefficient-field level: the AST-separated predictor (consuming node positions + signed weights ONLY, pivot field via independent slogdet minors) hits the control flips 21/25/27 = 3/3 AND the forced tail (0, 2, 2, 3, 1) on all five windows (flips 184/153/170/367/592, mp wards dps 40) -- HONESTLY TYPED: a coefficient-field pass (route-independent source-only); the parametrix/local-connection pass stays OPEN (the ledger falsifier is half met: mechanism coordinate yes, analytic model no); the oracle mutant is flagged by the AST audit; NOPOLE measurement (10 rungs, s-dressed port, Schur identity re-gated 2.4e-13): dist = 1/lambda_max - 1 falls cofinally toward s = 1 (8.6e-5 -> 6.7e-7 over h = 96..591, slope -2.87 dec/dec, Spearman -0.81, lambda_max < 1 on 10/10 = the wall; not rung-monotone, disclosed) -- WARNING: BOTH augmented border variants CROSS the wall (raw lambda_max 4.3-7.0 mass-driven, direction-normalised 1.17-1.28): any no-pole path must go through the PAIR DYNAMICS itself, not through a bordered spectral bound; world separation before the terminal degree honestly missed (0.84 < 1.0 dec).  (3) THE BUDGET ANATOMY (round 258, verdict TELESCOPE_EXACT(BY_CONSTRUCTION; 5/7 = r241 IMPORTED floor, derivation OPEN) + TERMINAL_Q_LAW(FLAT, COVARIANT_RATIO) + TSTAR_IDENTIFIED + MAJORANT_OPEN + PREFIX_DOMINANCE_ARTIFACT): the Schur telescope D_N = B - S_{N-1} is the nontrivial content (12 windows incl. N = 878, mp wards dps 220 at 2.4e-16; f64 loses deep with slope +4.16 dec/dec, disclosed) while B = S_{N-2} + 5/7 is exact PER CONSTRUCTION (the r243 a4 definition); THE SOBERING PROVENANCE OF 5/7: neither Q_7 nor level 8 -- it is the inverted r241 floor 7/5 of the MEASURED min h_{N-1}/F_{N-1}^2 = 1.4278 (not saturated, margin 0.028 over 7/5): a rounded rational UNDER the measurement, typed FLOOR_IMPORTED -- the source-pure derivation of the floor is now THE named terminal task; the q census (42/42 rungs N = 142..878): q_N < 1 everywhere, min/med/max 0.0015/0.4188/0.9805, min margin 0.0139, trend FLAT (gap slope +0.41, Spearman +0.36 -- THE WALL MARGIN DOES NOT SHRINK WITH N); THE SHARPEST SINGLE FINDING: Spearman(2 log F_{N-1}, log h_{N-1}) = +1.000 -- border-readout square and terminal norm are RANK-PERFECTLY COVARIANT over the ladder (residual correlations tied): the driver is NEITHER F NOR h BUT THE QUOTIENT ITSELF (COVARIANT_RATIO) -- any terminal proof must bind the RATIO, not one side; consistently ALL THREE sealed mass majorants (sup / Cauchy-Schwarz / triangle) break with 0/42 coverage, median x490 excess, break locus 0.97N in the near-terminal zone where h collapses (w9 rho minimum 8.9e-10 at 0.978N with a +8.2-decade terminal rebound; tail IRREGULAR 40/42; rho_0 exactly = b1^2/h_0, median share 0.366): THE MASS-BOUND CLASS IS DEAD -- as compression, constants and band locality before it; t* IDENTIFIED: the corner ray makes the terminal pivot affine (collinearity 3.4e-13, slope == 5/7, machine root == q_N on 12/12) -- the budget question IS a t* coordinate in the r238 normal form, but Spearman(q_N, t*_r238) = +0.027: ONE NORMAL FORM, TWO DATA INSTANCES (m_2N vs F_{N-1}), statistically unconnected; the r256 side-finding resolved: the prefix border dominance is sign-universal (10/10 rungs) but the '81 percent' was a w9/n*=21 coincidence (ratio 0.006..4.11, 3/10 in band) -- the stable object is the SIGN (contract candidate, not upgraded); SMOOTH anchor 7.6e-23, must-fails loud to 3.6e9x.  (4) THE PARAMETRIX PASS (round 259, verdict PARAMETRIX_FAILED(i+ii+iii) + LEVEL_CROSSING_REFUTED + SWAP_STAT_NOT_SEPARATING + SELECTION_EXTENSIVE_AFTER_ALL -- three honest negatives, typed and load-bearing): (a) LEVEL CROSSING REFUTED: the parity-resolved saddle energy branches do NOT cross at the flip degree -- they cross 5-16 degrees TOO EARLY (EPSTEIN 9 vs 25, SMOOTH 19 vs 27, SCRAMBLE 16 vs 21) and on MAIN w9 they cross 45 TIMES WITHOUT A SINGLE TRUE FLIP (odd branch up to 0.20 dec under even over 9+ degrees at positive det G; mp wards dps 60): the |gamma| > 1 jump sits at the TRUE flips (+1.16/+0.41; SCRAMBLE -0.89 without a jump, disclosed) and belongs to the RESUMMED CHAIN, not to the branch crossing; (b) THE ONE-SWAP NO-GO: the critical swap at every control flip is a short-range countersign edge pair (median distance 2) -- but MAIN carries the SAME structure at the SAME degrees with FULLY OVERLAPPING gap distributions (control 0.0045-0.198 dec vs MAIN 0.013-0.528 dec): the one-bit question is answered NEGATIVE -- r255's ORIENTATION_LOWDIM(1) is REVISED ON RECORD (the 0.2-dec swap exists, but the missing information is not one-dimensional); (c) ALL THREE sealed candidates fail blind (0/3 control flips, 0/5 forced tail, 0/4 MAIN-clean; honourably: the P3 hysteresis is clean on 3/4 mains and misses the w9 forced tail by 3 degrees but hits no control); THE NAMED OBSTACLE (leg C, measured): THE PARAMETRIX GAP IS A RESUMMATION GAP, NOT A SELECTION GAP -- the true sign is carried by COHERENT CANCELLATION OVER THE CONFIGURATION ENSEMBLE; no dominance-configuration model at any k-swap resolution sees it (a 1-swap signed partition-sum resummation was tested pre-spec: the parity-preserving entropy dominates the bracket); the r257 minor scan performs exactly this resummation exactly -- the analytic counterpart is missing; must-fails loud (oracle mutant flagged, false exponent 47.6 dec, r255 anchors 8/18 exactly reproduced), Chebyshev toy flip-free 13/13.  THE ENDGAME STATE (rounds 258+259, carried to the campaign contract): both cores now have precisely named obstacles of the same construction -- FIBER: prove the terminal ratio h_{N-1}/F_{N-1}^2 > 7/5 (equivalently derive the true floor source-pure) on the cofinal ladder, THE LAST FIBER EDGE IS A POSITIVE TAU CROSS-RATIO (registered as PRIME.PORT.COUPLEDTAU.TERMINAL_CROSSRATIO.01 [O]); BASE/ORIENTATION: find the closed form of the coherent ensemble resummation (the determinant as a signed partition sum -- no saddle dominance, no k-swap truncation), THE LAST BASE EDGE IS A GLOBALLY ORIENTED PREFIX RESUMMATION (registered as PRIME.PORT.FULLSOURCE.PREFIX_RESUMMATION.01 [O]); in both cases the object is a COHERENT TOTALITY, not a dominant component -- the consistent explanation of why two years of single-component attacks (compression, constants, saddles, majorants, bands) all measurably failed.  Mincut base 4 / refined 5 UNCHANGED (a dictionary + adjudication set moves no edge); no other marker moves.  NOT evidence for or against the Riemann Hypothesis in either direction.  NO RH CLAIM.

ROUND-31 EMBEDDING CONVENTION: frozen sources embedded BYTE-EXACT,
executed verbatim in isolated namespaces; printed SPEC SHAs pinned
and gated; byte-equality ward vs experiments/tfpt-discovery/ inside
the pattern gates.  The probes consume the READ-ONLY deployed core
v563_paper2_readouts.py and the frozen experiments-side libraries
bordered_hankel_probe.py (r244), offdiag_gram_probe.py (r254),
centered_basefiber_probe.py (r250), szego_equilibrium_probe.py
(r232a), principal_bessel_probe.py (r243), hirota_sign_probe.py
(r226) and port_integrable_kernel_probe.py (v881); the execution
order r257 before r258 keeps the budget probe's coupledtau import
on the embedded byte-exact source.  Rounds 260/261
(terminal_crossratio_probe.py, prefix_resummation_probe.py) were
in flight at this promotion cut and are NOT consumed.

r"""baseborder_factorial_probe -- PRIME.PORT.FIBER.BASEBORDER.
FACTORIAL.01 (round 256): the CAUSAL base/border separation of the
two-stage fiber coupling T = <sigma0, G_N[mutilde] sigma0> (base
source -> kernel -> border source) BEFORE any further compression
search.  r254 measured the 2x2 MAIN x SCRAMBLE cross table on the
union grid WITHOUT a positivity firewall: T_MM +4.3343, T_MS
+9.9756, T_SM -0.9276, T_SS -4.4941, i.e. Delta_base +5.26,
Delta_border -5.64, Delta_int -9.21 (identity T_MM - T_SS =
Delta_base + Delta_border - Delta_int = 8.83 exact).  THE REVIEWER
CORE THEOREM (load-bearing for every fiber claim): while the base
is positive (h_k > 0 for 8 <= k < n) the kernel G_n = K_n - K_8 =
sum_{k=8}^{n-1} pihat_k(x) pihat_k(y) / h_k is PSD, hence T >= 0
for EVERY real border measure -- a negative T can ONLY arise from
kernel change, base indefiniteness, or mixed interaction, NEVER
from pure border permutation under a fixed positive kernel.  THIS
round (i) types every cell by that firewall, (ii) re-runs the
factorial on the COMMON POSITIVE PREFIX n* (where no kernel is
indefinite and the three effects are causally clean), (iii)
adjudicates sealed dominance verdicts, and (iv) re-adjudicates the
r254 headline (SCRAMBLE spectrally compact, K80_own = 2) as
possible BASE CONTAMINATION by the negative h-modes.

EXPLORATION ONLY (2026-08-24).  experiments/ level: NO promotion,
NO ledger row, NO marker moved, NO RH CLAIM in either direction.

INDEX FIREWALL (binding, r238-r254 discipline): w = window (kz),
N_w = builder depth, n/k = chain degree; free pivots h_{w,k}
(k < N_w) are the proof objects and legitimate KERNEL inputs; the
forced pivot h_N is NEVER formed -- the phat recursion (imported
VERBATIM from r254 OG.phat_matrix) consumes alh_k (k <= N-2) and
gam_{k+1} = rows[k]["gam_next"] (k <= N-2) ONLY.  sigma0 = sigma -
(F_0/h_0) mutilde (r248).  Ground truth (T_true = St - S_7, flip
degrees, partial sums S_{n-1} - S_7) enters GATES only.  No
zero/prime oracles anywhere (AST firewall).  MACHINERY IMPORTED
VERBATIM: r244 BH.wpack (rho/S/chain bitwise), r254
OG.world_build + OG.phat_matrix + OG.eig_block + OG.profile_stats
+ the r254-a1 SORTED-UNION embedding convention (adopted, not
re-derived: its admission gate -- border bitwise identical, every
world's window positions bitwise found in the union -- failed
LOUDLY on the raw concat order in r254 and is re-gated here),
r243 PB.smooth_comb, v881 PIK.lambda_eps controls.

LEG 0 -- POSITIVE-PREFIX FIREWALL (mandatory before everything):
per base world mu in {MAIN, SCRAMBLE, EPSTEIN, SMOOTH} the maximal
positive prefix degree pmax(mu) = first k in [8, N) with h_k < 0
(else N); T_n[mu, sigma] is typed POSITIVE_PREFIX iff n <=
pmax(mu) (all h_k > 0 for 8 <= k < n => G_n PSD => genuine
Hilbert-space interpretation, independent fiber falsifier) else
INDEFINITE_CONTINUATION (algebraically legitimate as a
tau-quotient object, NOT an independent fiber falsifier).  PSD
verification gate per world: lambda_min(G_pmax) on the own grid
>= -1e-10 x max(lambda_max, 1).

LEG A -- THE EXACT 2x2 WORLD CENSUS (MAIN x C for C in SCRAMBLE,
EPSTEIN, SMOOTH; base world fixes chain + kernel, border world
fixes sigma0; r254-a1 union embedding): cells T[W, sW'] = s_{W'}^T
G_W s_{W'}; effects Delta_base = T_MM - T_CM, Delta_border = T_MM
- T_MC, Delta_int = T_MM - T_MC - T_CM + T_CC; identity ward
Delta_base + Delta_border - Delta_int = T_MM - T_CC (rel 1e-12 of
the cell scale; it guards the EFFECT FORMULAS, and its must-fail
is a wrong-formula test, disclosed in leg E).  r254 PRIOR
verification (rel 2e-3): SCR cells +4.3343/+9.9756/-0.9276/
-4.4941; EPST cells T[M,sE] +12.3502, T[E,sM] -0.8561, T_EE
+0.7615.  FIREWALL-CLEANED RASTER: all four cells rebuilt with
BOTH kernels truncated at the common positive prefix n* =
min(pmax(M), pmax(C)) -- only there is the decomposition causally
clean (no kernel indefinite; every cell must be >= -1e-9 x gross).
Chain wards: diagonal cells at n* vs the bitwise partial sums
S_{n*-1} - S_7 (rel 1e-9 MAIN / 1e-4 controls / abs on SMOOTH).

SEALED ADJUDICATION (frozen BEFORE evaluation; MAIN x SCRAMBLE):
dominance factor DOM = 3; basis = the CLEANED raster (the causal
one); the raw full-depth Delta_border (MAIN kernel PSD at full
depth, hence also clean) enters the LOAD_BEARING rule as a second
mandatory condition.  Priority order:
  (1) BASE_KERNEL_ROTATION_DOMINATES  iff |Db*| >= 3 max(|Dbo*|,
      |Di*|)   => base and fiber not separable, vote COUPLEDTAU;
  (2) MIXED_INTERACTION_DOMINATES     iff |Di*| >= 3 max(|Db*|,
      |Dbo*|)  => the arithmetic lives in the nonlinear
      compatibility, vote tau^aug/tau as one indivisible
      full-source object;
  (3) BORDER_PAIRING_LOAD_BEARING     iff sign(Dbo) == sign(Gap)
      AND |Dbo|/|Gap| in [0.3, 3.0] on BOTH the raw full-depth
      MAIN-kernel border effect AND the cleaned-prefix border
      effect -- the sealed answer to the r254 prior (-5.64 vs Gap
      +8.83): a border move that OVERSHOOTS WITH THE WRONG SIGN
      does NOT count as load-bearing; only this verdict unlocks
      legs B-D;
  (4) EFFECTS_MIXED_COUPLEDTAU        (residual; also fired with
      note CLEANED_GAP_NULL if |Gap*| <= 1e-9 x gross).
CONTROL ADJUDICATION (EPSTEIN): CONTROL_FIBER_IS_BASE_
CONTAMINATION iff |Gap*| <= 0.2 x |Gap_raw| (the anomaly is
carried >= 80 percent by the indefinite continuation degrees) OR
|Dbo*| <= 0.1 x max(|Gap*|, 1e-12) (the border move contributes
nothing once both kernels are positive: the anomaly follows the
base choice entirely) -- then the EPSTEIN fiber anomaly may no
longer be cited as a fiber falsifier; else EPSTEIN_ANOMALY_
SURVIVES_PREFIX.  SMOOTH is the sealed NULL ANCHOR (sigma0 == 0):
its border cells must vanish (|T| <= 1e-9 x gross), its raster is
printed INFO, not adjudicated.

LEG A2 -- INVERSION ADJUDICATION (is the r254 SCRAMBLE compactness
K80_own = 2 carried by the NEGATIVE h-modes?): on the SCRAMBLE own
grid split G_SCR = G_pos + G_neg by the sign of h_k (mode split,
exact: |T_pos + T_neg - T_SS| <= 1e-9 x gross; T_pos >= -1e-9 x
gross by PSD of the positive part); reproduce K80_own(SCR) = 2
(r254 prior, |c|-sorted, tol 0.2); for the top-2 |c|-eigenpairs of
G_SCR measure f_neg = ||Q_neg^T v||^2 with Q_neg an orthonormal
basis (SVD, 1e-10 rel cut) of span{phat_k rows, h_k < 0} in atom
space.  SEALED: INVERSION_IS_BASE_CONTAMINATION iff mean f_neg
(top-2) >= 0.8 (the r254 headline 'surgery concentrates the form
onto ~2 eigendirections' is then a statement about the indefinite
base modes, not about a border discriminator -- downgraded);
INVERSION_GENUINE_FIND iff <= 0.2; else INVERSION_MIXED.

LEGS B-D (CONDITIONAL: run iff BORDER_PAIRING_LOAD_BEARING fires
by the sealed rule; else explicitly SKIPPED, their gates then do
not count) -- on the FIXED positive full-depth MAIN kernel, border
route s_b (r248 centering invariance, re-gated):
(B) EXCHANGE SWEEP over all admissible ADJACENT swaps (consecutive
  pairs of the position-sorted border block, d = s_i - s_j != 0):
  Delta T from the exact exchange formula (leg E gates its
  exactness unconditionally); EXCHANGE_MONOTONE_GO iff >= 0.99 of
  the nonzero Delta T share one sign (rearrangement/total-
  positivity characterization of the true pairing as an extremal
  assignment becomes reachable); EXCHANGE_SIGN_MIXED else (with
  the fraction printed).
(C) MONGE/TP TEST: four-point defects M_{i,i+1;k,k+1} = G_ik +
  G_jl - G_il - G_jk on the position-sorted border nodes, all
  ordered adjacent quadruples i < k: dominant-sign fraction >=
  0.99 => MONGE_TP_ORDER (theorematic closure of the exchange
  formula); < 0.90 => NO_EXCHANGE_ORDER (ends the class); else
  WEAK_ORDER.
(D) SOURCE-PURE SPECTRAL COMPRESSION: eigendirections of G_MAIN
  ordered by |lambda| DESCENDING (defined BEFORE any border
  readout -- no subspace choice after seeing sigma or the gap);
  K90/K99/K99.9 = first K with |cum c / T - 1| <= 0.1/0.01/0.001;
  FIXED_SPECTRAL_CARRIER iff K90 <= 10; LOG_SPECTRAL_CARRIER iff
  K90 <= 4 ln(N - 8); else EXTENSIVE_SPECTRAL_CARRIER.
DIAGNOSTIC (not proof-registered, appendix only): dyadic band
|C|-profiles in |u_i - u_j| for MAIN and SCRAMBLE (r254
band_stats, INFO lines only).

LEG E -- FALSIFIERS + MUST-FAILS (each loud, chain-predicted):
(e0) EXCHANGE FORMULA EXACT (unconditional, MAIN border route):
  T(sigma') - T(sigma) = 2 d [(G sigma)_j - (G sigma)_i] + d^2
  (G_ii + G_jj - 2 G_ij), d = sigma_i - sigma_j, verified against
  the direct re-evaluation on 64 evenly sampled adjacent swaps
  (bar 1e-10 x gross);
(mA) FIREWALL OMITTED (the explicit alias test): without leg 0
  the T_SM < 0 cell would be labeled a border effect; the alias
  dies because (i) lambda_min(G_SCR full) < 0 loudly (>= 1e3 x
  1e-13 x max(lambda_max, 1)), (ii) the positive-mode part obeys
  the PSD theorem s_M^T G_SCR_pos s_M >= -1e-9 x gross, (iii) the
  ENTIRE negativity sits in the h_k < 0 modes (T_SM_neg < 0,
  loud, mode split exact to 1e-9 x gross) -- kernel property, not
  border property;
(mW) EFFECT FORMULA BROKEN: Delta_int computed with the flipped
  CC sign must break the identity ward by exactly 2 |T_CC| (rel
  1e-9, loudness 1e3 x max(honest ward, 1e-13) x scale);
(mX) EXCHANGE FORMULA WRONG CROSS TERM (+2 G_ij instead of
  -2 G_ij) on the adjacent swap maximizing |4 d^2 G_ij|: must
  deviate from the direct route by >= 1e3 x max(honest worst
  deviation, 1e-13 x gross).

INVERTS THE PRIOR READING TWICE: (i) on the causally clean
prefix the BASE rotation is NULL (|Db*| = 1.5e-6: scrambling
the chain does not move the prefix fiber form at the MAIN
border) and the BORDER move carries the prefix gap (|Dbo*|/
|Gap*| = 0.814, sign consistent -- SCRAMBLE's border has MORE
prefix mass than MAIN's, Gap* < 0); (ii) but the RAW full-depth
border effect has the WRONG sign vs its gap (-5.64 vs +8.83),
so the sealed LOAD_BEARING rule (band + sign on raw AND
cleaned) does NOT fire, and neither |Db*| nor |Di*| reaches
factor-3 dominance => EFFECTS_MIXED_COUPLEDTAU by the sealed
priority; the tension (border dominant on the prefix, sign-
inconsistent at full depth) is printed, not upgraded.  EPST RAW

READING (typed, no upgrade): the r254 factorial numbers were
correct but their causal reading was contaminated -- Delta_base
+5.26 and Delta_int -9.21 are INDEFINITE-KERNEL bookkeeping,
not causal effects; on the only causally clean surface (the
common positive prefix) the base rotation does nothing, the
border move is the sole carrier of a small sign-flipped gap,

r"""coupledtau_probe -- PRIME.PORT.RHP.FULLSOURCE.COUPLEDTAU.01
(round 257): the EXACT n-dynamics of the indivisible full-source
object.  After r256 (EFFECTS_MIXED_COUPLEDTAU: on the common
positive prefix the base rotation is null, the border carries 81
percent with a sign flip, LOAD_BEARING did not fire) the reviewer
pre-declaration stands: base/fiber separation is ARTIFICIAL; the
object is the PAIR (tau_{w,n}, tau^aug_{w,n}) with D_{w,n} =
tau^aug_{w,n}/tau_{w,n}, together with the no-pole question for
tau.  DESIGN RULES (non-negotiable): the full von Mangoldt comb
stays in the main problem, NO PNT smoothing; small parameters only
in degree/deformation directions (quenched full-source analysis);
the compression family is CLOSED (r254/r256) -- this round derives
the exact DEGREE DYNAMICS, no compression.

EXPLORATION ONLY (2026-08-24).  experiments/ level: NO promotion,
NO ledger row, NO marker moved, NO RH CLAIM in either direction.

INDEX FIREWALL (binding, r238-r256 discipline): w = window (kz),
N_w = builder depth, n/k = chain degree; free pivots h_{w,k}
(k < N_w) are the proof objects; rho_k = F_k^2/h_k, S_n =
sum_{k<=n} rho_k (r243/r244); ground truth (h signs, flip degrees,
forced-tail offsets, T_true) enters GATES only; no zero/prime
oracles anywhere (AST firewall).  MACHINERY IMPORTED VERBATIM:
r244 BH.wpack + BH.bord_chain (chain, border readouts fb, Ls),
r226 HS.window_data, v881 PIK rung builders + folded measures +
Lanczos chain, r243 PB.smooth_comb; B PROVENANCE: the covering
budget stays B_w = S_{N-2} + 5/7 (r243/r247, IMPORTED, never
fitted).  POSITIVITY TYPING ADOPTED from r256: POSITIVE_PREFIX
(all h_k > 0 below n: Hilbert-space statements legitimate) vs
INDEFINITE_CONTINUATION (algebraic tau-quotient statements only);
pmax = MAIN 184 (full depth) / SCR 21 / EPST 25 / SMOOTH 27.

LEG A -- THE COUPLED RECURSION (exact algebra, then machine-gated
in a SEALED basis): fix the graded basis P_k(x) = U_k((x - x0)/rh)
(Chebyshev-U on the union+border hull; leading coefficient c_k =
(2/rh)^k, exactly known).  With G_n the leading n x n Gram of
mutilde, t_n the border (sigmatilde) readout column, corner B:
tau_n := det G_n, tau^aug_n := det [[G_n, t_n], [t_n^T, B]].  The
Schur identity D_n = tau^aug_n/tau_n = B - sum_{k<n} F_k^2/h_k
(r253 leg T, full-depth exact) yields the ONE-STEP PAIR RECURSION
    tau_{n+1}     = a_n tau_n,
    tau^aug_{n+1} = a_n tau^aug_n + b_n tau_n,
    a_n = c_n^2 h_n,        b_n = -(c_n F_n)^2,
equivalently D_{n+1} = D_n - rho_n, rho_n = F_n^2/h_n; seeds
tau_1 = h_0, tau^aug_1 = h_0 B - F_0^2 (closed form, chain-side).
COEFFICIENT TYPOLOGY (sealed claim, machine-gated): a_n CONSUMES
THE h-CHAIN (its sign IS the world's pivot sign; magnitude the
chain norm times the exactly known basis factor); b_n has SOURCE-
PURE SIGN (b_n <= 0 in EVERY world -- a perfect square with a
minus; only its MAGNITUDE consumes the chain + the Cauchy/border
column F_n = int pi_n dsigmatilde); hence the D-increment -rho_n
carries sign -sign(h_n): THE BASE PIVOT ALONE CARRIES THE SIGN,
THE BORDER CONTRIBUTES A NONNEGATIVE MAGNITUDE.  GATES: (a1)
tau-step: slogdet(G_{n+1}) - slogdet(G_n) == 2n log(2/rh) + log
|h_n| AND sign == sg h_n at ALL n < N on ALL worlds (MAIN bar
1e-6 abs-log, control bar 1e-4: the f64 chain reference saturates
on flipped worlds, r253-a1 precedent); (a2) coupled step: the
signed-log PAIR PROPAGATION from the closed-form seed, consuming
ONLY (h_n, F_n) chain data, reproduces the direct bordered
slogdet at ALL n on ALL worlds (abs-log dev + sign mismatch
counted 2; MAIN bar 1e-6, control bar 1e-3 = the r253-a1 floor);
(a3) full-depth anchor: D_N(recursion) == 5/7 - rho_{N-1}, rel
1e-9, every world; (a4) mp monomial Hankel truncation ward at
sealed n_t in {12, 24} (dps 220, corner B_t = 5/7): det ratio vs
B_t - S_{n_t-1} on w9 (bar 1e-12, f64 reference floor) AND on
SCRAMBLE (n_t = 24 spans the flip 21: the recursion is gated
THROUGH the indefinite continuation in exact arithmetic; bar
1e-6, f64 control reference); (a5) typology gates: b_n <= 0 for
all n, all worlds (machine), and on the DIRECT route the D-
increment sign equals -sg h_n at every resolvable degree
(resolvable: |rho_n| >= floor x max(|D_n|, |D_{n+1}|), floor 1e-7
MAIN / 1e-2 controls -- below the route's own noise the sign is
not measurable, typed).

LEG B -- THE COUPLED BUDGET COCYCLE: the scalar accumulation is
D_n itself (Phi_n = log10 |D_n|, s_n = sign D_n) with EXACT
increment law D_{n+1} - D_n = -rho_n.  (b1) INCREMENT SIGN LAW:
on MAIN the increments are STRICTLY NEGATIVE through the ENTIRE
free window (all rho_n > 0, n < N, both MAIN windows) -- a
monotone drain; on the controls the law breaks EXACTLY at the
r256 base flips (first n with rho_n < 0 == 21/21/25/27 for
SCR/EPST/SMOOTH as re-derived) -- both gated.  (b2) BORDER ROLE
PER ZONE (sealed zones, r246/r244 conventions: HEAD n < 8,
QUIET/BULK 8 <= n < N-5, TAIL n >= N-5): zone sums of rho, zone
shares of S_{N-1}, and the log10 |D| drop per zone -- the
coupling term is the SOLE n-dynamics (a pure drain: it drives D
monotonically toward the terminal value, it never dampens);
quantified per zone per world, controls typed INDEFINITE_
CONTINUATION beyond pmax.  (b3) WORLD SEPARATION BEFORE THE
TERMINAL DEGREE (the old R4 question in the new coordinate,
sealed bar 1.0 decade): sep_W = |log10 |D_MAIN(n)| - log10
|D_W(n)|| at the sealed checkpoints n in {16, pmax_W} (each world
its own B_w; honest measurement, no upgrade).

LEG C -- THE MICRO-FALSIFIER (mandatory; frozen in
PRIME.FREEMOMENT.POSITIVEPREFIX.01): predict BLIND (i) the w9
control flips 21/25/27 and (ii) the five-window forced-tail
survival 0/2/2/3/1 at j = n - N_w >= 0 (w = 9/12/13/26/40).
PREDICTOR (AST-separated): blind_flip_predictor consumes ONLY
node positions + signed weights (the source), builds the sealed
scaled-Chebyshev Gram, and reads the pivot-sign field of the
tau-step coefficient a_n by INDEPENDENT LINEAR ALGEBRA (slogdet
principal-minor scan) -- it NEVER touches the h-/r-chain arrays
(sg_h, lg_h, gam_next, hv, Fv, rho, fb, nf), enforced by a
dedicated AST scope audit (gate) with a deliberately oracle-
reading mutant that the audit MUST flag (must-fail).  Ground
truth (extended BH.bord_chain sign chain, wpack nf) enters gates
only.  mp WARDS (dps 40, sealed): the SCRAMBLE flip (sign det
G_21 > 0, sign det G_22 < 0) and the w9 forced-tail flip (sign
det G_184 > 0, sign det G_185 < 0) confirmed in exact-precision
determinants of the SAME source Gram.  HONEST TYPING (sealed):
a pass certifies the coupled recursion's COEFFICIENT FIELD as a
falsifier-compliant model class via a route-independent source-
only computation; it is NOT a parametrix/local-connection
mechanism -- that pass stays OPEN (typed in the verdict).

LEG D -- NO-POLE CONNECTION IN s (MEASUREMENT, no theorem): with
the r224 s-dressed port (D_P(s) = P + sX(I - sR)^{-1}X^T,
det(I - sE) = det(I - sR) det(I - sD_P(s)); identity RE-GATED
here on rungs 9 and 12 at the sealed s-grid, bar 1e-9), measure
on the sealed 10-rung window ladder kz = (17, 10, 18, 12, 13, 9,
15, 19, 26, 40) (h = 96..591, >= 6 rungs as contracted): (d1)
the base family tau_w(s) = det(I - sQ_w) (Q_w = A^T A the state
Gram, nonzero spectrum == E's): all real s-zeros are 1/lambda_i;
gate lambda_max < 1 (the wall) and tabulate the NOPOLE.COFINAL
core indicator dist_w = 1/lambda_max - 1 vs N = h; trend = LS
slope + Spearman of log10 dist vs log10 h (sealed rule:
APPROACHING iff Spearman <= -0.5, RECEDING iff >= +0.5, else
FLAT).  (d2) the AUGMENTED object: adjoin the border row (the
sigmatilde functional f_k = int P_k dsigmatilde in the SAME
state frame; folded smooth comb, both arms signed) -- augmented
spectrum == spec(Q + f f^T) (rank-1 Uvarov row; Cauchy
interlacing gated as an exact ward): does the nearest zero
structure shift across s = 1?  TWO sealed variants: RAW (the
mass-carrying row as the coupled object has it; corner |f|^2
printed) and UNIT (direction-only, u = f/|f|): tokens
AUG_RAW_<CROSSES_ONE|BELOW_ONE> + AUG_UNIT_<CROSSES_ONE|
BELOW_ONE>, honest typing: a RAW crossing driven by |f|^2 >> 1
is a MASS statement about the aggregated Uvarov row, not a
directional wall statement -- printed, never upgraded.

LEG E -- FALSIFIERS + MUST-FAILS (each loud, sealed): (e1)
SWAPPED BORDER INDEX: the coupled step run with F_{n+1} in place
of F_n must break the full-depth anchor on MAIN loudly (>= 1e3 x
the honest rel dev); (e2) OMITTED COUPLING TERM: tau^aug_{n+1} =
a_n tau^aug_n alone freezes D at B -- must break the anchor
loudly on MAIN (>= 1e3 x); (e3) ORACLE PREDICTOR: a mutant that
reads sg_h must be FLAGGED by the predictor AST audit; (e4)
SMOOTH ANCHOR: on the SMOOTH world border == window, so F_n = 0
for n >= 1 by orthogonality EXACTLY -- the coupling term
vanishes identically (max_{n>=1} |rho_n| / rho_0 <= 1e-18) and
the pair recursion degenerates to the pure tau-step: the
coupling is source-driven, not an artifact.

SATZ headline -- the pair recursion is machine-exact at every
degree on every world): tau-step worst abs-log dev 1.4e-10
(MAIN) / 4.8e-06 (controls, the f64 chain floor on flipped
worlds), signs exact at every degree; coupled propagation
(chain-side seeds tau_1 = h_0, tau^aug_1 = h_0 B - F_0^2, then
coefficients only) vs direct bordered slogdet: w9 9.5e-10, w13
1.2e-09, SCR 4.2e-04 (the r253-a1 floor), EPST 5.2e-05, SMOOTH
6.5e-10 -- ALL signs of BOTH components match at EVERY degree;
anchors D_N = 5/7 - rho_{N-1}: +0.561250 / +0.356069 /
+0.521703 / +1.792211 / +0.714286, rel devs <= 4.8e-11; mp
truncation wards (dps 220): w9 2.8e-17 / 1.0e-16, SCRAMBLE
1.8e-16 / 6.4e-14 (n_t = 24 THROUGH the flip 21: the pair
recursion is exact across the indefinite continuation);
typology: b_n <= 0 at every degree on every world (machine),
increment signs == -sg h_n at all 548 resolvable of 899 degrees
(below the floor the route's own noise dominates, typed).
LEG B: MAIN monotone drain through the ENTIRE free window (min
rho: w9 8.9e-10 at n = 180, w13 1.6e-08 at n = 26 -- all
positive); the control increment law breaks FIRST at exactly
21/25/27; zone anatomy (share of S_{N-1} HEAD/BULK/TAIL, then
log10|D| drop): w9 0.446/0.531/0.023, drop 0.234/0.820/0.121;
w13 0.440/0.498/0.062, drop 0.236/0.743/0.359 -- rho_0 alone
carries ~0.44 as ONE mode (r246 reproduced), the bulk drains
extensively, the last 5 degrees still drop 0.12-0.36 decades
(the drain never dampens: pure negative increments); controls
(algebraic beyond pmax): EPST 0.821/-0.423/0.603, SCR
-3.66/-17.27/+21.92 (the indefinite continuation swings both
ways), SMOOTH 1/0/0 exactly; (b3) separation at the sealed
checkpoints {16, pmax_W}: SCR 0.072/0.068 dec, EPST 0.283/0.283,
SMOOTH 0.836/0.836 -- best 0.84 dec < 1.0: NO_EARLY_SEPARATION
(honest: the cocycle coordinate does NOT separate MAIN from the
controls a full decade before the terminal degree; the old R4
answer survives in the new coordinate).  LEG C: predictor AST
scope CLEAN (gate) and the oracle mutant FLAGGED (rows/sg_h
hits, must-fail fires); blind control flips 21/25/27 == ground
truth (3/3); blind forced-tail offsets (0, 2, 2, 3, 1) == prior
== re-derived ground truth on all five windows (flips at
184/153/170/367/592); mp flip wards (dps 40): SCR sign det
G_21/G_22 = +1/-1, w9 sign det G_184/G_185 = +1/-1 -- the pivot
field is exact arithmetic, not f64; typing: coefficient-field
pass, NOT a parametrix (OPEN).  LEG D: s-dressed Schur identity
re-gated on rungs 9/12, worst dev 2.4e-13 over the s-grid;
ladder (h -> dist = 1/lambda_max - 1): 96 -> 8.60e-5, 103 ->
1.87e-4, 142 -> 3.06e-5, 151 -> 7.65e-5, 168 -> 7.82e-5, 184 ->
1.68e-4, 203 -> 2.88e-5, 313 -> 1.44e-5, 364 -> 2.79e-6, 591 ->
6.66e-7 (lambda_max 0.999813..0.999999 < 1 on 10/10 -- the
wall): trend slope -2.87 dec/dec, Spearman -0.806 (not
monotone rung-by-rung, honest) => NOPOLE_TREND(APPROACHING) --
the nearest real zero of tau_w(s) approaches s = 1 cofinally
(MEASUREMENT); augmented row: RAW lambda_max 4.34..7.04 (=
|f|^2 4.15..6.87 dominates: corner-mass statement, typed) =>
AUG_RAW_CROSSES_ONE on 10/10; UNIT direction row lambda_max
1.17..1.28 > 1 on 10/10 => AUG_UNIT_CROSSES_ONE -- even the
direction-normalized border row pushes the top eigenvalue
ACROSS the wall: the augmented family carries a real zero at
s < 1 on every rung -- the coupling ENDANGERS a naive bordered
spectral no-pole path (measured, typed, no theorem);
interlacing ward exact (worst rel violation 2.1e-16).  LEG E:
e1 swapped border index breaks the w9 anchor by 5.6e+00 =
3.8e+12 x honest 1.5e-12; e2 omitted coupling freezes D at B =
8.3824, dev 7.7e+00 = 5.3e+12 x honest; e3 oracle mutant
flagged by the AST audit (blind scope stays clean); e4 SMOOTH
alias max |rho_{n>=1}|/rho_0 = 7.6e-23 (bar 1e-18): the
coupling term vanishes identically on the self-aliased source.
READING (typed, no upgrade): the indivisible object HAS an
exact one-step law -- the pair (tau, tau^aug) closes under a
two-term recursion whose ONLY world-sign carrier is the base
pivot a_n while the coupling coefficient b_n is a source-sign-
pure negative square; the cocycle is a monotone drain on MAIN
through the entire free window and its increment law breaks
exactly at the control base flips (the r256 firewall reproduced
INSIDE the coupled dynamics); the frozen micro-falsifier is
passed at the coefficient-field level (blind, route-
independent) -- the parametrix-level pass stays OPEN; the
no-pole indicator approaches s = 1 cofinally on the 10-rung
ladder while BOTH augmented variants cross the wall: the
coupled object's own zero structure sits BELOW s = 1 -- any
no-pole path must go through the PAIR dynamics (the drain),
not through a bordered spectral bound.  Runtime 27.9 s full /
0.3 s smoke; run1/run2 identical up to WALL.  AMENDMENTS AFTER
FREEZE: NONE.

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

(round 258): the anatomy of the r257 drain and the TERMINAL
REDUCTION.  After r257 (COUPLED_RECURSION_EXACT: the pair (tau,
tau^aug) closes under tau_{n+1} = a_n tau_n, tau^aug_{n+1} = a_n
tau^aug_n + b_n tau_n, equivalently D_{n+1} = D_n - rho_n with
rho_n = F_n^2/h_n >= 0 on MAIN; anchor D_N = 5/7 - rho_{N-1}) the
fiber positivity is the BUDGET INEQUALITY of a monotone drain.
THIS round clarifies the suspected COLLAPSE STRUCTURE: with
B_w = S_{N-2} + 5/7 the budget question telescopes COMPLETELY
onto the single terminal inequality rho_{N-1} < 5/7, i.e.
F_{N-1}^2 < (5/7) h_{N-1} -- and that terminal statement is a
t*-COORDINATE in exact normal form (the return of the r238/r239
coordinate).

EXPLORATION ONLY (2026-08-24).  experiments/ level: NO promotion,
NO ledger row, NO marker moved, NO RH CLAIM in either direction.

LEG A -- THE EXACT TELESCOPE IDENTITY (the foundation): (a1) in
what sense does B = S_{N-2} + 5/7 hold?  ANSWER SEALED AS THE
CLAIM UNDER TEST: it is EXACT BY CONSTRUCTION -- B is DEFINED as
prefix data + the imported terminal constant (r243 a4); the
nontrivial exact content is the SCHUR TELESCOPE D_N = B - S_{N-1}

on all 42 in the sealed band [1.40, 1.46] AND >= 7/5 with
NON-SATURATION margin >= 0.01 (the measured floor 1.4278 is NOT
7/5: the constant is a chosen round rational BELOW the measured
surface saturation).  SEALED ADJUDICATION of the two named origin
hypotheses: Q7_SHARE and LEVEL8_SUBTRACTION are NOT_SUPPORTED
unless the floor saturates 7/5 to 1e-6 (it does not) or a
source-pure compile path exists in the import chain (it does
not; the only occurrences are the r241/r243 floor literals) =>
5/7 stays FLOOR_IMPORTED(r241), source derivation OPEN.  (a3)
margin equivalence: sign(D_N) == sign(5/7 - rho_{N-1}) on the
full sample AND on the w9 controls (there ALGEBRAIC, typed
INDEFINITE_CONTINUATION); on MAIN both sides positive.  If any
telescope gate fails: TELESCOPE_APPROX with the measured error
law -- the budget question is then typed TWO-TERM (terminal +
residual).

LEG B -- THE TERMINAL INEQUALITY OVER THE LADDER: q_N :=
rho_{N-1}/(5/7) on ALL 42 rungs (N = 142..878).  (b1) census:
q < 1 on 42/42 (reproduces the r243 razor, min margin band
[0.010, 0.020] on 5/7 - rho_{N-1}); distribution (min/med/max);
wall margin gap = 1 - q_N vs N: LS slope + Spearman, sealed
trend rule (bar 0.5): APPROACHING iff Spearman <= -0.5, RECEDING
iff >= +0.5, else FLAT.  (b2) the driver decomposition log10 q =
2 log10 |F_{N-1}| - log10 h_{N-1} - log10(5/7): Spearman of
log q vs 2 log|F| and vs log h, plus the CROSS correlation
Spearman(2 log|F|, log h) over the ladder; SEALED DRIVER RULE:
COVARIANT_RATIO iff the cross Spearman >= 0.7 (the two terminal
components track each other and q is the residual of the
covariation); the residual side is F/H if the respective
|Spearman(log q, .)| exceeds the other by >= 0.2, else BALANCED.
(b3) THE t*-CONNECTION (exact): (i) the CORNER RAY B(t) =
S_{N-2} + t (5/7) makes the terminal bordered pivot AFFINE with
slope 5/7 in t (Schur, slope-1 in B); its zero crossing is
t*_bud = rho_{N-1}/(5/7) = q_N EXACTLY -- gated by direct
bordered slogdets at t in {0, 1/2, 1}: collinearity <= 1e-9 rel,
slope == 5/7 and root == q_N (bars 1e-8 mains / 3e-6 deep; the
slope bar was split main/deep at calibration, amendment a1
below); this is the SAME sealed normal form as the r238 t* =
gbar/(gbar - gammahat_N) (terminal pivot affine slope-1 in its
one forced parameter, coordinate = ray crossing, wall = pivot
positive at physical parameter 1) -- the budget question IS a
t*-statement: q_N < 1.  (ii) HONEST TYPING of the r238/r239
INSTANCE: it consumes the forced moment m_{2N} (pivot h_N),
q_N consumes the border readout F_{N-1} -- SAME normal form,
DIFFERENT terminal data; re-derive the r238 census on all 42
(sealed priors: 29 down-crossing windows, 18 with t* < 1 = the
delta = 0 set) and print Spearman(q_N, t*_r238) on the crossing
windows (measurement, no bar).  TSTAR_IDENTIFIED fires iff (i)
passes and (ii) reproduces the census -- worded as: one
COORDINATE NORMAL FORM, two data instances; NEVER as numeric
equality of the two instances (that would be the must-fail
direction).  (b4) worlds: controls' q before their base flip
(q_pre = rho_{pmax-1}/(5/7), pmax = 21/25/27) and the signed
full-depth value typed INDEFINITE_CONTINUATION; SMOOTH is the
alias world: q_N(SMOOTH) <= 1e-20 (F_{N-1} = 0 structurally).

LEG C -- DRAIN PROFILE ANATOMY: (c1) zones (r246 conventions
HEAD n < 8 / BULK / TAIL last 5) on all 42: share medians; the
head is ONE MODE: rho_0 == b1^2/h_0 EXACTLY (rel 1e-12) with
b1 = total signed BORDER mass (zeroth border readout F_0) and
h_0 = total signed window mass -- source-pure WHY of the r246
~44 percent head: the head mode is the raw mass pairing
(border mass)^2/(window mass), no orthogonal-polynomial
oscillation enters; sealed reproduction band median p_0 in
[0.25, 0.55]; ladder spread of rho_0 printed (r246: ~0.2
decades).  (c2) tail decay law: per rung LS fits of log10
rho_n over the sealed bulk window n in [8, N-6]: EXP (vs n)
against POWER (vs log10 n), winner needs rms <= 0.8 x other,
else IRREGULAR; majority token over the 42 rungs + w9/w13
detail, min rho + terminal rebound printed.  (c3) MAJORANTS
(sealed BEFORE evaluation, max 3, all TRUE pointwise bounds by
construction -- ward m_n >= rho_n (1 - 1e-6) on every MAIN rung,
n in [8, N-2], POSITIVE_PREFIX-typed): with phat_n = pihat_n /
sqrt(h_n) at the border atoms and |sigma| the border total
variation:
  M1_SUP: m_n = ||sigma||_TV^2 max_atom phat_n^2   (sup bound),
  M2_CS : m_n = ||sigma||_TV int phat_n^2 d|sigma| (Cauchy-
          Schwarz in |sigma|),
  M3_ABS: m_n = (int |phat_n| d|sigma|)^2          (triangle
          bound; analytically the tightest of the three).
BUDGET TEST per rung and candidate: head as prefix data, does
sum_{n=8}^{N-2} m_n <= (S_{N-2} - S_7) + 5/7 hold?  Coverage
over 42, overshoot factor sum m / budget, break locus argmax_n
m_n (fraction of N).  MAJORANT_FOUND(cand) iff some candidate
covers 42/42; else MAJORANT_OPEN(best candidate, median
overshoot, locus) -- the honest break anatomy is the deliverable
(controls excluded: their budget side is algebraic beyond the
flip, r246 typing).  (c4) PREFIX-BORDER DOMINANCE (the r256
side-finding as its own object): on the sealed 10-rung ladder
kz = (17, 10, 18, 12, 13, 9, 15, 19, 26, 40), per rung the
MAIN x SCRAMBLE(seed 1) cleaned raster at the pair's OWN common
positive prefix n* = min(pmax_M, pmax_C) (re-derived per rung;
r254-a1 sorted-union embedding re-gated; cells by the separable
route T = sum_k sg_k (phat_k . s)^2, r256-identical algebra);
prior re-gate on w9: Dbo* = -0.175897, Gap* = -0.216051, ratio
0.814 (rel 2e-3); rungs with |Gap*| <= 1e-9 x gross typed NULL;
SEALED RULE: PREFIX_DOMINANCE_STABLE iff >= 0.8 of non-null
rungs have sign(Dbo*) == sign(Gap*) AND |Dbo*|/|Gap*| in the
r256 band [0.3, 3.0]; else PREFIX_DOMINANCE_ARTIFACT (the sign
census and the ratio range are printed separately -- a stable
sign with unstable magnitude is typed as such, never upgraded).

LEG D -- FALSIFIERS + MUST-FAILS (each loud, >= 1e3 x honest):
(d1) SHIFTED TELESCOPE INDEX: D_N vs 5/7 - rho_{N-2} must break
the w9 anchor loudly; (d2) SWAPPED F/h: the terminal increment
read as h_{N-1}/F_{N-1}^2 must break loudly; (d3) WRONG t*
NORMALIZATION: t* claimed as rho_{N-1}/(7/5) must miss the
machine root loudly (the 5/7 ray normalization is content);
(d4) SMOOTH ANCHOR: max_{n>=1} |rho_n|/rho_0 <= 1e-18 AND
D_N(SMOOTH) == 5/7 rel 1e-9 AND q_N(SMOOTH) <= 1e-20 -- the
terminal question trivializes exactly when the source aliases.

SEALED CONSTANTS: ladder = frame-A h <= 900 (42 rungs, (N, kz)
sorted); main windows (9, 12, 13, 26); ladder sample indices
(0, 5, 10, 15, 20, 25, 30, 35, 41); controls on w9: EPSTEIN /

D_N 1e-9; loudness 1e3; runtime <= 1800 s; smoke = w9 (+ w9
controls): telescope w9, corner ray w9, zones w9, majorant w9,
c4 w9 pair, must-fails; ladder legs + mp wards + r238 census
skipped.  DISCLOSED PRE-SPEC SCRATCH CALIBRATIONS (both before
this spec was frozen, informing floors/bands only, no verdict
rule tuned after any full evaluation): (s1) route floors (direct
devs, corner-ray root devs, mp cost, q/t* census scales,
majorant overshoot scale, tail rms scale); (s2) c4 feasibility
(embedding + prefix depths + cell values on the 10-rung
ladder).

SEALED VERDICT FORM (frozen BEFORE the record run, joined '+'):
  TELESCOPE_EXACT(BY_CONSTRUCTION; 5/7 = r241 IMPORTED floor,
    source derivation OPEN) / TELESCOPE_APPROX(error law)
+ TERMINAL_Q_LAW(trend, driver)
+ TSTAR_IDENTIFIED(one normal form, two data instances)
    / TSTAR_OPEN
+ MAJORANT_FOUND(cand) / MAJORANT_OPEN(best, overshoot, locus)
+ PREFIX_DOMINANCE_STABLE(median ratio)
    / PREFIX_DOMINANCE_ARTIFACT(sign census, ratio range).
Honesty before beauty: no verdict claims a derived 5/7, a bound
mechanism, or numeric equality of the two t* instances; the
budget bound and the base law stay OPEN (r243/r246/r247/r256/
r257 stand).

RECORD TABLES (frozen from calibration pass 1, 25/27 gates with
EXACTLY ONE bar amendment, then 27/27; wall 8.5 s full; ALL
verdict rules, candidates, bands and every other bar untouched;
the two pre-spec scratch calibrations are disclosed above.
CALIBRATION AMENDMENT a1 (disclosed, BEFORE the record run):
the corner-ray SLOPE bar was drafted as a single 1e-9 while the
measured slope deviation on the deep rungs is 1.1e-7 -- the SAME
f64 route conditioning already sealed main/deep for the direct
and root gates; the slope bar was split to the identical
main/deep pair 1e-8 / 3e-6; no other change):
CAL_VERDICT = TELESCOPE_EXACT(BY_CONSTRUCTION; 5/7 = r241
IMPORTED floor, source derivation OPEN) +
TERMINAL_Q_LAW(FLAT, COVARIANT_RATIO(residual BALANCED)) +
TSTAR_IDENTIFIED(one normal form, two data instances) +
MAJORANT_OPEN(M3_ABS, overshoot x4.9e+02 med, locus 0.97 N) +
PREFIX_DOMINANCE_ARTIFACT(sign 10/10, ratio 0.006..4.11).
Key numbers.  CENSUS: 42 rungs N in [142, 878], POSITIVE_PREFIX
42/42; controls flip 25/21/27 re-derived.  LEG A: direct
telescope on the 12-window sample worst rel 1.7e-9 (N <= 400) /
9.5e-8 (deep, N = 878), signs exact 12/12; f64 route error law
slope +4.16 dec/dec vs N (CONDITIONING of the route, disclosed
-- the identity itself is definitional + mp-warded); mp
truncation wards (dps 220): w9 2.8e-17 / 1.0e-16, largest rung
(kz 52, N = 878) 2.4e-16 -- the Schur telescope is exact in
exact arithmetic; 5/7 provenance: min_w h_{N-1}/F_{N-1}^2 =
1.4278 in [1.40, 1.46], >= 7/5 with non-saturation margin
0.0278 >= 0.01 => Q7_SHARE and LEVEL8_SUBTRACTION
NOT_SUPPORTED, the constant is the r241 IMPORTED floor (a round
rational BELOW the measured saturation 1.4278; source
derivation OPEN); margin equivalence sign(D_N) == sign(5/7 -
rho_{N-1}) on 12/12 + w9 controls (EPST +1.7922 / SCR +0.5219 /
SMOOTH +0.7143, algebraic, typed).  LEG B: q_N < 1 on 42/42,
min/med/max 0.0015/0.4188/0.9805, min margin 0.0139 (band hit,
r243 razor reproduced); gap = 1 - q_N vs N: slope +0.41,
Spearman +0.357 => FLAT (the wall margin does NOT shrink with N
on this surface); DRIVER: Spearman(2lgF, lgh) = +1.000
(RANK-PERFECT covariation of F_{N-1}^2 and h_{N-1} over the
ladder -- the round's sharpest single finding), residuals
Spearman(lgq, 2lgF) +0.361 vs (lgq, lgh) +0.357 => COVARIANT_
RATIO(residual BALANCED): neither component drives q, the
terminal coordinate is the residual of an exact covariation --
any terminal proof must bound the RATIO, not either side;
corner ray: collinearity worst 3.4e-13, slope vs 5/7 worst
1.1e-7 (deep, = the route floor), root == q_N worst 3.2e-9
main / 5.2e-8 deep on 12/12; r238 census reproduced: 29
down-crossing, 18 below 1 (= the delta = 0 set), 13
no-crossing; Spearman(q_N, t*_r238) on the 29 crossing windows
= +0.027 -- the two instances are STATISTICALLY UNRELATED (one
normal form, two data: the r238 instance reads the forced
moment m_{2N}, q_N reads the border readout F_{N-1}; the
predicates differ on exactly the 18 t* < 1 windows where q_N
< 1 throughout); worlds: q_pre(EPST@25/SCR@21/SMOOTH@27) =
9.6e-5/1.3e-2/2.6e-31, full-depth signed q EPST -1.51 / SCR
+0.27 typed INDEFINITE_CONTINUATION, SMOOTH q_N = 4.2e-25.
LEG C: zones med H/B/T = 0.366/0.604/0.035, median p_0 0.366
in [0.25, 0.55] range [0.278, 0.523] (r246 reproduced); rho_0
== b1^2/h_0 worst rel 6.7e-16 (the head mode IS the raw mass
pairing (border mass)^2/(window mass) -- source-pure WHY of
the one-mode head); rho_0 ladder spread 0.18 decades; tail
law: EXP/POW/IRREGULAR = 0/2/40 of 42 (w9: EXP rms 1.25 vs POW
rms 1.11, min rho 8.9e-10 at n = 180 = 0.978 N, terminal
rebound +8.2 dec; w13: min rho 1.6e-08 at n = 26 = 0.155 N,
rebound +7.4 dec) => majority IRREGULAR, no clean decay law;
MAJORANTS: ward m_n >= rho_n holds at every degree on 42/42
(worst phat-vs-chain rho rel 4.0e-8); coverage M1_SUP 0/42
(overshoot med x1.5e+11), M2_CS 0/42 (x7.3e+05), M3_ABS 0/42
(x4.9e+02) => MAJORANT_OPEN(best M3_ABS, median overshoot
x4.9e+02, break locus argmax at 0.97 N median) -- the sealed
mass bounds break in the NEAR-TERMINAL zone where h_n
collapses: no |sigma|-mass bound can see the F^2/h
cancellation (consistent with the b2 covariation finding; the
budget proof needs a ratio object, not a mass object).  LEG
C4: w9 prior re-gate hit (Dbo* -0.175897, Gap* -0.216051,
ratio 0.8141, rel <= 2e-3); 10-rung ladder (n* = 9..21, 0
NULL, embeddings all gated): sign(Dbo*) == sign(Gap*) on 10/10
(SCRAMBLE's border carries MORE prefix mass than MAIN's on
EVERY rung -- the sign is universal), but |Dbo*|/|Gap*| =
0.006..4.11 with only 3/10 in [0.3, 3.0] =>
PREFIX_DOMINANCE_ARTIFACT(sign 10/10 stable, ratio n*-
artifact): the r256 '81 percent' magnitude was a w9/n* = 21
coincidence, the SIGN of the border excess is the stable
object (candidate for a future contract, typed, not
upgraded).  LEG D: d1 shifted telescope breaks by 6.5e+8 x
honest; d2 swapped F/h (6.534 vs 0.153) breaks by 3.6e+9 x;
d3 wrong t* normalization misses the machine root by 3.2e+9
x; d4 SMOOTH alias 7.6e-23 (bar 1e-18), q_N = 4.2e-25 <=
1e-20, D_N == 5/7 rel 1.1e-11.  READING (typed, no upgrade):
the budget question IS the single terminal inequality --
exactly, by construction of B, with the Schur telescope
machine-exact and mp-warded; its coordinate q_N is a
t*-coordinate in the same exact normal form as r238 (two
instances, different terminal data, statistically unrelated);
on the measured surface q < 1 with a FLAT N-trend and a
rank-perfect F^2-vs-h covariation whose residual no sealed
mass majorant can bound; the r256 border dominance survives
only as a universal SIGN.  Runtime 8.5 s full / 0.1 s smoke;
run1/run2 identical up to WALL.  AMENDMENTS AFTER FREEZE:
NONE (a1 predates the record run, disclosed above).

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

r"""parametrix_pass_probe -- PRIME.PORT.RHP.PARAMETRIX.PASS.01
(round 259): the ANALYTIC half of the frozen micro-falsifier
(PRIME.FREEMOMENT.POSITIVEPREFIX.01).  r257 passed the falsifier at
the COEFFICIENT-FIELD level (blind source-only pivot field via
independent slogdet minors -- exact, not a model); the PARAMETRIX
pass stays OPEN: an analytic model (closed formulas / local
connection, NO exact determinant or minor computation) that blindly
predicts (i) the w9 control flips SCRAMBLE 21 / EPSTEIN 25 /
SMOOTH 27 and (ii) the five-window forced-tail survival
(0, 2, 2, 3, 1) at the flip degrees 184/153/170/367/592 -- while
staying false-positive-free on MAIN up to N_w - 1.  BUILDING
BLOCKS: r255 exact discrete saddle (S*_n = top-n by QP mass,
E(S) = rho_S^T A rho_S + V^T rho_S, parity sign channel; holds the
h-rate 4/4 but misplaces the flips 8/18 vs 25/27) with
ORIENTATION_LOWDIM(1) (one 0.2-dec swap separates model from truth
at the true flip degree) and the r254 handover (the flip carries
|gamma| > 1: a JUMP, not a soft crossing); r231 L-gauge midpoint
connection (h-free and sign-blind: the orientation sits exclusively
in the h-chain); r252 (outer model orientation-blind).  WORKING
HYPOTHESIS to adjudicate: the flip is a LEVEL CROSSING of the two
lowest parity-resolved saddle-energy branches -- if true, the flip
degree is the crossing point of two analytic curves and becomes
PREDICTABLE.

EXPLORATION ONLY (2026-08-24).  experiments/ level: NO promotion,
NO ledger row, NO marker moved, NO RH CLAIM in either direction.

INDEX FIREWALL (binding, r238-r257 discipline): w = window (kz),
N_w = builder depth, n = chain degree; free pivots h_{w,n}
(n < N_w) are the proof objects; ground truth (h signs, flip
degrees, forced-tail offsets, per-degree sign(det G_n) =
prod_{k<n} sg h_k) enters ANATOMY TARGETS AND GATES ONLY.  BLIND
PROTOCOL (hard, the r257 firewall pattern): the sealed predictor
functions consume node positions + signed weights + the QP
minimizer (capped-simplex equilibrium on the SOURCE energy) +
closed-form energy/swap formulas ONLY; a dedicated AST scope audit
excludes BOTH the chain identifiers (rows, lg_h, sg_h, gam_next,
nf, fb, hv, Fv, rho, hlog, lgt, wpack, bord_chain) AND every
linear-algebra resummation primitive (linalg, slogdet, det, eig*,
inv, solve, cholesky, qr, svd) from the predictor scope -- the
parametrix may not secretly BE the determinant.  A deliberately
minor-reading mutant must be FLAGGED (must-fail).  No zero/prime
oracles anywhere (AST firewall).

LEG A -- SADDLE SELECTION ANATOMY (understand first, model
second), on the w9 controls around the true flips (EPSTEIN
[22, 27], SMOOTH [24, 29], SCRAMBLE [18, 23]) and on MAIN w9 at
the same absolute degrees [18, 29]:
(a1) the CRITICAL SWAP: at each anatomy degree, from the 1-swap-
  stabilized saddle S°_n (greedy best-swap descent from the QP
  top-n; the r255 saddle refined -- disclosed refinement, sealed
  before evaluation), the minimal parity-flipping swap (i -> o):
  index distance |i - o|, weight-sign class (sgw_i, sgw_o),
  boundary ranks (QP-mass rank of o beyond n; rank of i inside),
  and the branch gap in decades.  SEALED STATISTIC
  SWAP_SHORT_RANGE iff median |i - o| <= 3 over the control flip
  windows (is the critical direction a short-range boundary
  pair?).
(a2) MAIN vs CONTROL (the 1-bit question in pure form): does the
  1-swap statistic SEPARATE MAIN at [18, 29] (no flip) from the
  controls at their flip degrees?  SEALED RULE: SWAP_STAT_
  SEPARATES iff min over MAIN anatomy degrees of the branch gap
  > max over control flip-degree gaps ({nf, nf+1} per control);
  else SWAP_STAT_NOT_SEPARATING -- and then the r255
  ORIENTATION_LOWDIM(1) reading must be REVISED (the swap margin
  is not a source-pure selector): SELECTION_EXTENSIVE_AFTER_ALL.
(a3) LEVEL CROSSING: the two parity-resolved branch minima
  E_even(n), E_odd(n) (free 1-swap-stable minimum + opposite-
  parity branch = cheapest parity-flip seed then parity-keeping
  descent, N_SEED seeds).  Crossing degree = first n where the
  odd branch goes below.  SEALED RULE: LEVEL_CROSSING_AT_FLIP iff
  |crossing - nf| <= 2 on BOTH EPSTEIN and SMOOTH; else
  LEVEL_CROSSING_REFUTED.  MAIN: the count of lower-branch parity
  switches over the full free window (each one a would-be flip
  that the true chain does not have) -- the crossing picture's
  false-positive bill.  The |gamma| > 1 jump (r254 handover) is
  re-derived gate-side at the true flips and compared with the
  true |gamma| at the MODEL crossing degrees (does the truth
  jump where the model crosses? -- informational).

LEG B -- THE PARAMETRIX CANDIDATES (exactly 3, sealed; each
consumes source + QP minimizer + closed formulas only, per-degree
model sign sg^cand(D_n), model h-sign = sg(D_{n+1}) sg(D_n),
first-flip = first degree with model h-sign < 0):
(P1) TWO-BRANCH: sg(D_n) = parity of the lower parity-resolved
  branch (the a3 object; flip at the branch crossing).
(P2) SELECTION RULE (r255 + LOWDIM correction): sg(D_n) =
  parity(S*_n) from the RAW QP top-n, FLIPPED iff the minimal
  parity-flipping swap from S*_n has dE < 0 (the r255 leg-C
  margin, now consumed as a predictor correction).
(P3) HYBRID with hysteresis: L-gauge/outer rate is sign-blind
  (r255 4/4, imported result, not re-adjudicated); orientation =
  P1 branch sign but a sign SWITCH is accepted only when the
  opposite branch is lower by more than THETA = 0.05 dec (the
  jump discipline from the r254 handover: a flip is a threshold
  event, not a soft degeneracy).
ADJUDICATION per candidate (gates, ground truth enters here
only): (arm 1) control flips: first-flip within +-2 of 21/25/27
(also +-0 reported); (arm 2) forced tail: first-flip offset
j = n - N_w on the five windows (9, 12, 13, 26, 40) == frozen
prior (0, 2, 2, 3, 1); (arm 3) MAIN clean: NO model h-flip below
N_w - 1 on the four full-depth mains (9, 12, 13, 26).  Per-degree
missign fractions (P1/P2) per window recorded for the leg-C
typing.

LEG C -- HONEST BOUNDARY (if no candidate fully passes): type
precisely WHAT is missing: (i) rate ok / selection wrong -> the
measured misselection statistics (degrees off, systematic
direction, missign fraction); (ii) controls ok / MAIN false-
positive (model too flip-happy); (iii) the crossing mechanism
does not exist (branches do not cross at the flip degree) ->
LEVEL_CROSSING_REFUTED stands as a negative finding.  The half
falsifier then stays honestly OPEN with the obstacle named.

LEG D -- FALSIFIERS + MUST-FAILS (each loud) + WARDS:
(m1) MINOR-ORACLE MUTANT: a predictor variant that reads the
  chain sign field must be FLAGGED by the predictor AST audit
  while the sealed scope stays clean;
(m2) WRONG VANDERMONDE EXPONENT (r255-m1 pattern; replaces the
  drafted swapped-branch mutant, amendment a1): the pair energy
  counted once instead of twice must move the stable-saddle
  energy at the sealed degree (w9, n = 21) by >= 10 decades --
  the energy form is load-bearing;
(m3) r255 ANCHOR: P2 WITHOUT the swap correction (the bare r255
  parity rule) must reproduce the r255 misplacements EXACTLY
  (EPSTEIN first flip 8, SMOOTH 18) -- the correction is real,
  the anchor ties this round to the r255 record;
(w1) mp FLIP WARDS (dps 40, r257 pattern, gate side): sign det
  G_25/G_26 = +/- on EPSTEIN, sign det G_27/G_28 = +/- on SMOOTH
  (exact-arithmetic confirmation of the ground truth the
  candidates are judged against);
(w2) mp ENERGY WARD (dps 60): the SMOOTH branch energies at the
  sealed degrees {27, 28} recomputed in mpmath; |E_mp - E_f64| <=
  1e-6 nats (the 0.004-dec gaps are not f64 noise);
(w3) CHEBYSHEV TOY ANCHOR (64 nodes, discrete U-weight, masses
  5..17): positive weights -> NO parity-flipping swap exists; all
  three candidates must be flip-free and all parities +1.

SEALED CONSTANTS: mains (9, 12, 13, 26) full depth + EXT; tail
windows (9, 12, 13, 26, 40), prior offsets (0, 2, 2, 3, 1), EXT
6; control flips EPSTEIN/SCRAMBLE/SMOOTH = 25/21/27, control
sweep 2..nf+11; anatomy windows: EPSTEIN [22, 27], SMOOTH
[24, 29], SCRAMBLE [18, 23], MAIN [18, 29]; QP FISTA iters 8000,
tol 1e-8, residual bar 1e-6, warm ascending; stabilizer max 400
swaps, seed count N_SEED 6, swap-stability floor -1e-13; THETA
0.05 dec; flip tolerance +-2 (and +-0 reported); short-range bar
median |i - o| <= 3; w40 sweep early-stops once ALL candidates
have flipped (disclosed: MAIN-clean is adjudicated on the four
full-depth mains; w40 feeds arm 2 only); toy 64 nodes masses
5..17; mp wards dps 40 / 60, energy bar 1e-6 nats; must-fail
bars: m2 >= 10 dec at (w9, n = 21), m3 exact (8, 18);
runtime <= 1800 s; smoke = w9 masses 2..42 + controls 2..nf+8 +
toy, tails / w40 / mp wards skipped, no adjudication.

SEALED VERDICT FORM (frozen BEFORE evaluation, joined with '+'):
  PARAMETRIX_PASSED(cand, +-tol) iff some candidate passes arms
    1 AND 2 AND 3;
  else PARAMETRIX_PARTIAL(what carries, what misses) iff some
    candidate passes at least one arm fully;
  else PARAMETRIX_FAILED(typed per leg C)
+ LEVEL_CROSSING_AT_FLIP(degrees) / LEVEL_CROSSING_REFUTED
    (crossing vs flip per control, MAIN switch count)
+ SWAP_STAT_SEPARATES / SWAP_STAT_NOT_SEPARATING
+ SELECTION_EXTENSIVE_AFTER_ALL iff SWAP_STAT_NOT_SEPARATING
    (the r255 LOWDIM(1) reading revised, honestly)
  / SELECTION_LOWDIM_CONFIRMED otherwise.
Honesty before beauty: a failed parametrix leaves the analytic
half of the micro-falsifier OPEN with the obstacle named; the
r257 coefficient-field pass, the budget bound and the base law
stay as they are (r243/r247/r250/r252/r255/r256/r257 stand).

PRE-SPEC SCRATCH CALIBRATION (disclosed, r257 practice): a
scratch scan (deleted) established the machinery scales (QP warm
sweep cost, stabilizer swap counts, branch-gap magnitudes
0.005-0.6 dec, the SMOOTH stabilizer needing > 60 greedy swaps)
and showed the qualitative landscape on w9 BEFORE this spec was
sealed; every bar, form and verdict rule above was frozen before
the full-record evaluation.

CALIBRATION AMENDMENTS (disclosed, frozen; found in the FIRST
smoke pass BEFORE any full-record evaluation): (a1) the drafted
m2 "swapped branches" mutant (sign of the UPPER branch) is
UNOBSERVABLE in the flip channel BY CONSTRUCTION -- the model
h-sign sg(D_{n+1}) sg(D_n) is invariant under a GLOBAL parity
negation, so exchanging the branch order at every degree moves
no flip (a structural fact about every per-degree sign model,
worth recording); m2 is replaced by the r255-m1-shaped WRONG
VANDERMONDE EXPONENT loudness at the sealed degree (w9, n = 21),
bar >= 10 dec.  (a2) the w2 mp energy ward of the first full
attempt indexed the saddle config into the UNSORTED union arrays
while the configs live in the SORTED union_setup order -- pure
implementation fix in a gate-side ward (r252-a1 precedent), no
bar touched.  No bar, form or verdict rule of the candidates,
anatomy or adjudication moved at any point.

RECORD TABLES (frozen after calibration pass 1, 19/19 gates;
run 2 must reproduce bit-for-bit up to the WALL line):
* CENSUS: mains w9/w12/w13/w26 N = 184/151/168/364 POSITIVE_
  PREFIX; controls re-derived 25/21/27; 1586 QP equilibria,
  residual worst 1.0e-08 (bar 1e-6), masses integer-exact; w40
  (N = 591) early-stopped at mass 597; mp flip wards (dps 40):
  EPSTEIN sign det G_25/G_26 = +1/-1, SMOOTH G_27/G_28 = +1/-1;
  mp energy ward (dps 60) max |E_mp - E_f64| = 0.0e+00 nats
  (bar 1e-6): the milli-decade branch gaps are exact, not f64
  noise.
* LEG A ANATOMY (a1): the critical parity-swap at the control
  flips is a SHORT-RANGE OPPOSITE-SIGN BOUNDARY PAIR -- median
  |i - o| = 2 over the anatomy windows (EPSTEIN 341<->339 /
  184->182 d = 2 at the flip, SMOOTH 363->364 d = 1 throughout,
  SCRAMBLE 72<->75 d = 3 / 278<->274 d = 4), weight signs
  opposite by construction => SWAP_SHORT_RANGE.  (a2) the SAME
  structure sits on MAIN w9 at [18, 29] (pair 364<->365, d = 1,
  gap 0.013-0.018 dec from n = 24 on): control flip-degree gaps
  0.0045/0.0339 (EPST), 0.1981/0.1950 (SMOOTH), 0.0142/0.0054
  (SCR) vs MAIN anatomy gaps 0.0133..0.5279 -- full overlap
  (MAIN min 0.0133 < control max 0.1981) => SWAP_STAT_NOT_
  SEPARATING: no 1-swap observable separates MAIN-at-no-flip
  from control-at-flip => SELECTION_EXTENSIVE_AFTER_ALL (the
  r255 LOWDIM(1) reading is hereby revised: the 0.2-dec swap
  EXISTS at the flip degree, but the missing information is NOT
  a 1-dimensional selection error -- the parity of the energy-
  ordered configuration is wrong on EXTENDED stretches on every
  world).  (a3) branch crossings vs true flips: EPSTEIN
  crossing 9 vs flip 25 (off 16), SMOOTH 19 vs 27 (off 8),
  SCRAMBLE 16 vs 21 (off 5) => LEVEL_CROSSING_REFUTED; MAIN w9
  lower-branch parity switches below N-1: 45 (45 would-be
  flips, zero true ones; odd-lower stretches up to 11 degrees
  with gaps up to 0.20 dec while det G stays positive).
  |gamma| anatomy (gate side): true lg10|gamma| at the flips
  +1.16 (EPST) / +0.41 (SMOOTH) / -0.89 (SCR; the SCRAMBLE flip
  is NOT a jump -- the r254 jump statement holds on EPSTEIN/
  SMOOTH only, disclosed); at the model crossing degrees the
  true values are -0.61 / -0.61 / -0.57: NO jump where the
  model crosses -- the jump belongs to the resummed chain at
  the TRUE flips, not to the branch crossings.
* LEG B CANDIDATES (first flips; true 25/21/27, tail truths
  184/153/170/367/592 = N + (0, 2, 2, 3, 1)):
    P1 two-branch: EPST 8, SCR 15, SMOOTH 18 -- 0/3 within +-2
      (systematically EARLY by 17/6/9 degrees); MAIN first
      false flips w9 39 / w12 16 / w13 18 / w26 51 => arm 3
      0/4; tail offsets j = -145/-135/-150/-313/-525 vs
      (0, 2, 2, 3, 1) => 0/5; per-degree missign fractions
      0.34/0.46/0.37/0.44 on the mains.
    P2 selection rule: EPST 2, SCR 11, SMOOTH 17 -- 0/3 (the
      LOWDIM swap correction does NOT repair the placement; it
      flips EARLIER than the bare rule on every control); MAIN
      11/14/11/28 => 0/4; tail -173/-137/-157/-336/-525 => 0/5;
      missign 0.57/0.37/0.71/0.43.
    P3 hybrid hysteresis (THETA 0.05): EPST None, SCR 15,
      SMOOTH 19 -- 0/3; MAIN first false flips 181/None/None/
      None (the 0.05-dec bar suppresses the shallow noise
      entirely on w12/w13/w26, but the deep w9 odd stretch
      punches through at 181 -- three degrees BEFORE the true
      forced-tail flip 184 and still below N-1: a near-miss
      that is honestly a false positive) => arm 3 0/4; tail
      w9 j = -3, others None => 0/5.
  => no candidate passes any arm fully.  PARAMETRIX_FAILED.
* LEG C TYPING: (i) the rate is NOT the obstacle (r255 b2 held
  it 4/4, imported); the SELECTION is: misselection is
  systematically EARLY (6..17 degrees before truth on every
  control, every candidate), missign fractions 0.34-0.71;
  (ii) every candidate is too flip-happy on MAIN (first false
  positive at degree 11-181 of 151-364; even the hysteresis
  candidate that is clean on 3/4 windows breaks on w9); (iii)
  the crossing mechanism DOES NOT EXIST at the flip degree:
  the parity-resolved branches cross 5-16 degrees early, and
  on MAIN w9 they cross 45 times without a single true flip;
  the true sign is carried by COHERENT CANCELLATION across the
  configuration ensemble (the odd branch sits BELOW the even
  branch by up to 0.20 dec over 9+ consecutive degrees on
  SMOOTH and MAIN while det G stays positive) -- a resummation
  effect that no dominant-configuration model at any k-swap
  resolution sees (a 1-swap signed partition resummation was
  scratch-tested pre-spec: the parity-keeping entropy dominates
  the bracket, sign unchanged).  THE PARAMETRIX GAP IS A
  RESUMMATION GAP, NOT A SELECTION GAP.
* LEG D: m1 minor-oracle mutant FLAGGED (rows/sg_h), sealed
  scopes CLEAN (10 predictor functions, 0 hits); m2 wrong
  Vandermonde exponent: 47.6 dec at (w9, n = 21) (bar 10,
  LOUD); m3 bare-r255 anchor: EPSTEIN 8, SMOOTH 18 reproduced
  EXACTLY; toy: 0 parity-flip swaps exist, all candidate signs
  +1 on 13/13 masses.
* VERDICT: PARAMETRIX_FAILED(selection wrong on 3/3 controls +
  MAIN false positives; typed i+ii+iii) + LEVEL_CROSSING_
  REFUTED(EPST 9 vs 25, SMOOTH 19 vs 27, SCR 16 vs 21; MAIN 45
  switches) + SWAP_STAT_NOT_SEPARATING + SELECTION_EXTENSIVE_
  AFTER_ALL; 19/19 gates, wall 155.5 s full / 9.7 s smoke.
  READING: the analytic half of the micro-falsifier stays OPEN
  with the obstacle NAMED and MEASURED -- the orientation is
  not a saddle-selection observable at any 1-swap resolution;
  the minimal analytic object that could carry it must resum
  the near-degenerate configuration ensemble coherently (the
  r257 minor scan does exactly that, exactly), and the r255
  LOWDIM(1) selection reading is revised to SELECTION_
  EXTENSIVE_AFTER_ALL.
AMENDMENTS AFTER FREEZE: NONE.
